Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to an information transmission method, device, and storage medium. Background Art

[0004] In 5G (5th Generation Mobile Communication Technology), different RRC (Radio Resource Control) information elements or RRC messages need to be defined in the standard protocol to carry the control plane information transmitted between the UE (User Equipment) and the RAN (Radio Access Network), so that the RAN can identify the corresponding control plane information based on the RRC information elements and RRC messages.

[0005] However, in the future 6G (6th Generation Mobile Communication Technology), RAN may be restructured into multiple wireless network functions, such as wireless access function, positioning function, perception function, AI (Artificial Intelligence) function, etc. The information exchanged between each separate wireless network function and the UE needs to be transmitted through the RAN. If the existing technology is still used to define a dedicated RRC information element or RRC message for each type of information in the standard protocol to carry the message, the workload will be large, the protocol will be cumbersome and complicated, the readability will be poor, and there may be coupling between different functional protocols.

[0059] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0060] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0061] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0062] In related technologies, signaling between UEs and networks in 5G includes RRC messages between the UE and the RAN, and NAS (Non-Access Stratum) messages between the UE and the CN (Core Network). NAS messages are carried over the RRC over the air interface, and RRC messages define multiple messages that can carry NAS information. In a base station architecture with separate gNB-CU (Centralized Unit) and gNB-DU (Distributed Unit), the RRC protocol terminates at the gNB-CU. In a base station architecture with separate gNB-CU-CP (Control Plane) and gNB-CU-UP (User Plane), the RRC protocol terminates at the gNB-CU-CP.

[0063] Figure 1 is a schematic diagram of the control plane protocol stack in the related art. As shown in Figure 1, the control plane protocol stack mainly includes NAS, RRC, PDCP (Packet Data Convergence Protocol), RLC (Radio Link Control), MAC (Medium Access Control), and PHY (Physical Layer). Among them, the PDCP layer provides encryption and integrity protection functions. The functions performed by the control plane in the RLC layer and MAC layer are consistent with those of the user plane. The RRC layer protocol terminates at the gNB and mainly provides broadcast, paging, RRC connection management, RB (Radio Bearer) control, mobility management, UE measurement reporting and control functions. The NAS layer terminates at the AMF (Access and Mobility Management Function) and mainly implements 5GS (5G System) functions such as mobility management, paging, and security control.

[0064] Among them, there is a NAS-MM (Mobility Management) protocol between the UE and the AMF in the CN. There are many protocols between the terminal and the core network function (excluding AMF) that need to be transmitted through the NAS-MM protocol. These protocols include: session management signaling, SMS, UE policy, LCS (Location Service). The NAS messages of these protocols are forwarded between the UE and the corresponding core network function through the AMF. Optionally, the NAS transmission of SM (Session Management), SMS (Short Messaging Service), UE Policy and LCS can be shown in Figure 2.

[0065] In addition, the 5G system architecture includes a set of NFs (Network Functions). NF is a processing function in the system that defines functional behavior and interfaces. NF can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, such as on a cloud infrastructure. The 5G system architecture is defined as a service-based architecture, that is, a system architecture that implements system functions by providing services to other authorized NFs through a set of NFs to access their services. NF service is a function that NF (as NF service producer) exposes to other authorized NFs (as NF service consumers) through a service-based interface. An NF service can support one or more NF service operations. An NF can provide different NF services.

[0066] In summary, in 5G, the RAN can only recognize two types of control plane information transmitted between the UE and the RAN: information generated by the RRC protocol layer itself and NAS information. The endpoints for these two types of information exchange are the base station and the AMF, respectively. The method for distinguishing these two types of information is to define different RRC information elements or RRC messages in the standard protocol to carry these two types of information. These RRC information elements and RRC messages are used to distinguish these two types of information.

[0067] However, in the future 6G, the RAN may be restructured into multiple radio network functions, such as radio access functions, positioning functions, perception functions, and AI functions. These separate radio network functions can evolve, develop, and deploy independently. Furthermore, in the future 6G, CN NFs may interact directly with the RAN, bypassing the AMF. For example, the SMF (Session Management Function) and the LMF (Location Management Function) can interact directly with the RAN. In other words, in the future 6G, more NFs (both in the RAN and in the CN) will interact with the UE in signaling, and the information exchanged between these NFs and the UE will need to be transmitted through the RAN. If, as in existing technologies, dedicated RRC information elements or RRC messages are defined in standard protocols for each type of information, this would be labor-intensive, result in cumbersome and complex protocols, and poor readability. Furthermore, there may be coupling between different functional protocols. Furthermore, existing technologies do not address the situation where a UE simultaneously interacts with multiple network functions of the same service / function type.

[0068] Therefore, in order to solve the above problems, the embodiments of the present disclosure propose an information transmission method, device and storage medium to support the interaction of information between multiple NFs and UEs, and when the UE interacts with multiple NFs of the same type at the same time, the RAN can forward the interactive information to the corresponding NF, the NF can identify the service corresponding to the interactive information, and the UE can deliver the interactive information to the corresponding processing entity within the UE.

[0069] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0070] The technical solutions provided by the embodiments of the present disclosure can be applicable to a variety of systems, especially future communication systems, such as 6G systems. For example, applicable systems may be GSM (Global System for Mobile Communications), CDMA (Code Division Multiple Access) system, WCDMA (Wide-band Code Division Multiple Access) system, GPRS (General Packet Radio Service) system, LTE (Long Term Evolution) system, LTE FDD (Frequency Division Duplex) system, LTE TDD (Time Division Duplex) system, LTE-A (Long Term Evolution Advanced) system, UMTS (Universal Mobile Telecommunication System), WiMAX (Worldwide Interoperability for Microwave Access) system, 5G system, etc. These various systems all include terminal devices and network devices. The system may also include a core network part, such as EPS (Evolved Packet System), 5GC (5G Core Network), etc.

[0071] The terminal devices involved in the embodiments of the present disclosure may refer to devices that provide voice and / or data connectivity to users, handheld devices with wireless connection capabilities, or other processing devices connected to wireless modems. In different systems, the names of terminal devices may also be different. For example, in a 5G system, the terminal device may be called a UE. A wireless terminal device can communicate with one or more CNs via a RAN. A wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with a wireless access network. For example, PCS (Personal Communication Service) phones, cordless phones, SIP (Session Initiated Protocol) phones, WLL (Wireless Local Loop) stations, PDAs (Personal Digital Assistants), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.

[0072] The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or may be named by another name. The network device may be used to interchange received air frames with IP (Internet Protocol) packets, acting as a router between the wireless terminal device and the rest of the access network; the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a BTS (Base Transceiver Station) in GSM or CDMA, a NodeB (network device) in WCDMA, an eNB or e-NodeB (evolutionary Node B) in an LTE system, a 5G base station (gNB) in a 5G network architecture (next generation system), a HeNB (Home evolved Node B), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure. In some network structures, the network device may include a CU (Centralized Unit) node and a DU (Distributed Unit) node, and the CU and DU may also be geographically separated.

[0073] The following describes the information transmission method, device, and storage medium according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0074] It should be noted that in the embodiments of the present disclosure, when the sending and receiving ends of different information are the same, the different information can be sent in the same message or in different messages. Each step in the embodiments of the present disclosure is not mandatory, and other steps may be included between the steps. The steps in the embodiments of the present disclosure are not limited to being executed in sequence, and some steps can be executed in parallel.

[0075] FIG3 is a flow chart of an information transmission method provided by an embodiment of the present disclosure.

[0076] It should be noted that the information transmission method of the embodiments of the present disclosure is applied to an access network device. Optionally, the access network device may be any device in a RAN. As an example, the access network device may be any logical functional entity in the RAN, such as a network function, a logical node, or a logical unit.

[0077] Optionally, the logical functional entity can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, which is not limited in the embodiments of the present disclosure.

[0078] As shown in FIG3 , the information transmission method may include steps: 301 - 302 .

[0079] Step 301: Receive first information sent by a first terminal device or a first logical function entity.

[0080] Among them, the first information is used to indicate the initiation of target information interaction, the target information interaction includes information interaction of target business or target function or target service, and the target information interaction is information interaction between the first terminal device and the first logical function entity.

[0081] The first logical functional entity is a logical functional entity in the network or a second terminal device, and the logical functional entity in the network is a logical functional entity in an access network or a logical functional entity in a core network.

[0082] It should be noted that the second terminal device is a terminal device other than the first terminal device. When the first logical function entity is the second terminal device, the target information interaction is the information interaction between the first terminal device and the second terminal device.

[0083] Optionally, when the first logical functional entity is the second terminal device, the first terminal device can interact with the logical functional entity in the second terminal device for target information. At this time, the logical functional entity that interacts with the first terminal device for target information is the logical functional entity in the terminal device other than the first terminal device.

[0084] Similarly, the first logical functional entity can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, which is not limited in the embodiments of the present disclosure.

[0085] For example, the first logical functional entity includes one or more of the following: a logical functional entity in an access network, a logical functional entity in a core network, or one or more of the following: a logical functional entity in a control plane, a logical functional entity in a user plane.

[0086] For another example, the first logical function entity may be at least one of the following: SMF, AMF, base station, base station centralized unit, base station user plane transmission unit, perception function, location / positioning function, AI function, short message function, UE policy function, user plane function, UE data transmission function in the access network, UE data transmission management / control function in the access network, data management / control function in the access network, radio connection management / control function, etc. UE data includes one or more of the following: data between the UE and the data network, data between the UE and a logical function entity in the network, and data between the UE and another UE.

[0087] The target business or target function or target service includes at least one of the following: UE data transmission, session management, short message, UE policy, location or positioning, perception, AI, core network business or function or service.

[0088] It should be noted that different services / functions / services may belong to the same type of service / function / service. For example, UE data transmission in slice 1 and UE data transmission in slice 2 both belong to services / functions / services of the UE data transmission type. For another example, session management in slice 1 and session management in slice 2 both belong to services / functions / services of the session management type. For another example, session management in session 1 and session management in session 2 both belong to either functions or services of the session management type. For another example, providing perception of capability / quality of service 1 and providing perception of capability / quality of service 2 both belong to services / functions / services of the perception type. For another example, perception of service 1 and perception of service 2 both belong to services / functions / services of the perception type. And so on.

[0089] It should be noted that in the embodiment of the present disclosure, the first terminal device can perform information interaction of multiple businesses / functions / services simultaneously. Optionally, the first terminal device can perform information interaction of multiple types of businesses / functions / services simultaneously, or the first terminal device can perform information interaction of multiple businesses / functions / services of the same type of business / function / service simultaneously. For example, the first terminal device can perform information interaction of session management and information interaction of UE policy simultaneously. For another example, the first terminal device can perform information interaction of session management of slice 1 and information interaction of session management of slice 2 simultaneously. For another example, the first terminal device can perform information interaction of perception of business 1 and information interaction of perception of business 2 simultaneously. And so on.

[0090] It should be noted that, in the embodiments of the present disclosure, there is a corresponding relationship between target information interaction and the first logical function entity. Optionally, a target information interaction can correspond one-to-one with a first logical function entity, that is, the first terminal device performs information interaction on a target business, target function, or target service with a first logical function entity. For example, the information interaction of session management of slice 1 corresponds to SMF1. The information interaction of session management of slice 2 corresponds to SMF2. Optionally, multiple target information interactions may correspond to a first logical function entity, that is, the first terminal device performs information interaction on multiple target businesses, target functions, or target services with a first logical function entity. As an example, when a first logical function entity contains multiple target businesses, target functions, or target services, the first terminal device can perform information interaction on multiple target businesses, target functions, or target services with the first logical function entity. For example, the information interaction of session management of session 1 and the information interaction of session management of session 2 correspond to the same SMF. For another example, the information interaction of perception of service 1 and the information interaction of perception of service 2 correspond to the same perception function.

[0091] In an embodiment of the present disclosure, the access network device can receive first information sent by the first terminal device or the first logical functional entity to indicate the initiation of target information interaction (information interaction between the first terminal device and the first logical functional entity) to inform the access network device that the first terminal device or the first logical functional entity wants to initiate target information interaction.

[0092] It should be noted that, in the embodiment of the present disclosure, if the first terminal device indicates that information interaction (target information interaction) of the target business or target function or target service is required, that is, the access network device receives the first information sent by the first terminal device, at this time, since the first terminal device does not indicate the first logical functional entity for target information interaction with the first terminal device, the access network device can determine the first logical functional entity corresponding to the target information interaction.

[0093] As a possible implementation, the access network device may determine, based on a target service, target function, or target service, a first logical functional entity for target information exchange with the first terminal device, where the first logical functional entity supports the target service, target function, or target service. Alternatively, the access network device may determine, based on a target logical functional entity type for target information exchange, the first logical functional entity for target information exchange with the first terminal device, where the first logical functional entity belongs to the target logical functional entity type. Alternatively, the access network device may receive a determination by a second logical functional entity of the first logical functional entity for target information exchange with the first terminal device.

[0094] Optionally, the access network device may indicate the target business or target function or target service to a logical function entity (second logical function entity), and the logical function entity indicates to the access network device the first logical function entity that performs target information interaction with the first terminal device. For example, for a target business or target function or target service included in a core network function, the access network device may indicate the target business or target function or target service to a logical function entity (e.g., AMF or NRF) in the core network, so that the logical function entity in the core network indicates to the access network device the first logical function entity that performs target information interaction with the first terminal device.

[0095] When the access network device indicates a target service, function, or service, the access network device may indicate one or more of the following: a service / function / service / logical function entity type of the target service, function, or service, and relevant parameter information of the target service, function, or service. When the access network device indicates a service / function / service type of the target service, function, or service, the first logical function entity includes a service / function / service of the service / function / service type. When the access network device indicates a logical function entity type of the target service, function, or service, the first logical function entity belongs to a logical function entity type.

[0096] It should be noted that, when the first terminal device indicates the need for information interaction (target information interaction) of the target business or target function or target service, the first terminal device may indicate one or more of the following: the business / function / service / logical function entity type of the target business or target function or target service, and relevant parameter information of the target business or target function or target service. When the first terminal device indicates the business / function / service type of the target business or target function or target service, the first logical function entity includes the business / function / service of the business / function / service type. When the first terminal device indicates the logical function entity type of the target business or target function or target service, the first logical function entity belongs to the logical function entity type.

[0097] It should be noted that in the embodiment of the present disclosure, if the first logical function entity indicates that information interaction (target information interaction) of the target business or target function or target service is required, that is, the access network device receives the first information sent by the first logical function entity, the first logical function entity can indicate to the access network device that it is the first terminal device that performs the target information interaction with the first logical function entity. Therefore, the access network device can determine that the target information interaction is the information interaction between the first terminal device and the first logical function entity.

[0098] When the first terminal device indicates that information interaction of a target business, target function, or target service is required (target information interaction), the first terminal device may optionally further send relevant service information of the information interaction of the target business, target function, or target service to the access network device. The first terminal device may instruct the access network device to initiate the target information interaction and send relevant service information to the access network device in one message or in different messages.

[0099] Similarly, when the first logical function entity indicates that information interaction of a target service, target function, or target service (target information interaction) is required, the first logical function entity may optionally further send relevant service information of the information interaction of the target service, target function, or target service to the access network device. The first logical function entity may instruct the access network device to initiate the target information interaction and send the relevant service information to the access network device in one message or in different messages.

[0100] Step 302: Indicate first indication information corresponding to the target information interaction to the first terminal device, and / or obtain first indication information corresponding to the target information interaction determined by the first terminal device.

[0101] The first indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the first logical function entity, and / or the first indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device.

[0102] It can also be understood that the first indication information is used to indicate relevant business information of the target information interaction between the first terminal device and the access network device.

[0103] In the embodiments of the present disclosure, the access network device may indicate first indication information corresponding to the target information interaction to the first terminal device, and / or obtain the first indication information corresponding to the target information interaction determined by the first terminal device. That is, the first indication information may be determined solely by the access network device, solely by the first terminal device, or jointly by the access network device and the first terminal device, and this is not limited in the embodiments of the present disclosure.

[0104] Optionally, the first indication information may be one of the following: number, identifier, index, radio bearer, logical channel, transport channel, physical channel.

[0105] It should be noted that in the embodiments of the present disclosure, a corresponding relationship exists between target information interactions and first indication information. Optionally, a target information interaction may correspond one-to-one with a first indication information. For example, first indication information 1 corresponds to target information interaction 1. First indication information 2 corresponds to target information interaction 2. Alternatively, multiple target information interactions may correspond to one first indication information. For example, target information interaction 1 and target information interaction 2 may both correspond to first indication information 1.

[0106] Assuming that target information interaction 1 (information interaction between the first terminal device and the first logical function entity 1) already corresponds to first indication information 1, if target information interaction 2 is information interaction between the first logical function entity 1 and the first terminal device or other terminal device or other logical function entity, then since the first logical function entity 1 already corresponds to first indication information 1, target information interaction 2 can correspond to first indication information 2 different from first indication information 1 or to first indication information 1, and this is not limited in the embodiments of the present disclosure. It can also be understood that the access network determines the first indication information corresponding to the target information interaction based on the first indication information corresponding to the first logical function entity. The first indication information corresponding to the target information interaction can be the first indication information corresponding to the first logical function entity.

[0107] As a possible implementation, the first indication information includes an indication information, so that the access network device can determine the first indication information corresponding to the target information interaction and indicate the first indication information corresponding to the target information interaction to the first terminal device. Alternatively, the first indication information corresponding to the target information interaction indicated by the first terminal device is received (in this case, the first indication information is determined separately by the first terminal device).

[0108] As another possible implementation, the first indication information includes first type indication information and first instance indication information, so that the access network device may perform at least one of the following operations:

[0109] Determine first type indication information in first indication information corresponding to target information interaction, and indicate the first type indication information corresponding to target information interaction to the first terminal device; or,

[0110] Determine first instance indication information in the first indication information corresponding to the target information interaction, and indicate the first instance indication information corresponding to the target information interaction to the first terminal device; or,

[0111] Determine first type indication information and first instance indication information in first indication information corresponding to target information interaction, and indicate the first type indication information and first instance indication information corresponding to the target information interaction to the first terminal device; or,

[0112] Receive first type indication information in first indication information corresponding to target information interaction indicated by the first terminal device; or,

[0113] Receive first instance indication information in first indication information corresponding to target information interaction indicated by the first terminal device; or,

[0114] Receive the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction indicated by the first terminal device.

[0115] Optionally, the first indication information may correspond to one or more of the following: information interaction of one or more services / functions / services, information interaction of a logical functional entity, and the first indication information may be per UE.

[0116] In summary, the first indication information can be provided in the following two ways:

[0117] Method 1: The first indication information includes one indication information.

[0118] The first indication information 1 corresponds to information interaction with business / function / service / logical function entity 1, and the first indication information 2 corresponds to information interaction with business / function / service / logical function entity 2. Business / function / service / logical function entity 1 and business / function / service / logical function entity 2 may be business / function / service / logical function entities of different types, or may be business / function / service / logical function entities of the same type, which is not limited in the embodiments of the present disclosure.

[0119] For example, first indication information 1 corresponds to information interaction of session management of slice 1. First indication information 2 corresponds to information interaction of session management of slice 2. First indication information 3 corresponds to information interaction of perception of service 1. First indication information 4 corresponds to information interaction of perception of service 2.

[0120] For another example, first indication information 1 corresponds to information interaction with logical function entity 1, which includes session management for slice 1. First indication information 2 corresponds to information interaction with logical function entity 2, which includes session management for slice 2. First indication information 3 corresponds to information interaction with logical function entity 3, which includes awareness of service 1. First indication information 4 corresponds to information interaction with logical function entity 4, which includes awareness of service 2.

[0121] Note: It is not excluded that multiple first indication information corresponds to one logical functional entity.

[0122] Mode 2: The first indication information includes first type indication information and first instance indication information.

[0123] The first type indication information indicates the type of a business / function / service / logical function entity. The first instance indication information indicates one or more of the following: information interaction of one or more businesses / functions / services in a business / function / service type, and information interaction of a logical function entity in a logical function entity type.

[0124] The first type indication information 1 corresponds to information interaction of business / function / service / logical function entity type 1, and the first type indication information 2 corresponds to information interaction of business / function / service / logical function entity type 2. The first instance indication information 1 corresponds to information interaction of business / function / service / logical function entity 1 of a given business / function / service / logical function entity type, and the first instance indication information 2 corresponds to information interaction of business / function / service / logical function entity 2 of the same given business / function / service / logical function entity type.

[0125] For example, the first indication information 1 corresponds to the information interaction of the session management of slice 1, and the first indication information 1 is a combination of the first type indication information 1 and the first instance indication information 1 (the first instance indication information 1 under the first type indication information 1). The first indication information 2 corresponds to the information interaction of the session management of slice 2, and the first indication information 2 is a combination of the first type indication information 1 and the first instance indication information 2 (the first instance indication information 2 under the first type indication information 1). The first indication information 3 corresponds to the information interaction of the perception of service 1, and the first indication information 3 is a combination of the first type indication information 2 and the first instance indication information 1 (the first instance indication information 1 under the first type indication information 2). The first indication information 4 corresponds to the information interaction of the perception of service 2, and the first indication information 4 is a combination of the first type indication information 2 and the first instance indication information 2 (the first instance indication information 2 under the first type indication information 2).

[0126] For another example, first indication information 1 corresponds to information interaction with logical function entity 1. Logical function entity 1 includes session management for slice 1. First indication information 1 is a combination of first-type indication information 1 and first instance indication information 1 (first instance indication information 1 under first-type indication information 1). First indication information 2 corresponds to information interaction with logical function entity 1. Logical function entity 1 includes session management for slice 2. First indication information 2 is a combination of first-type indication information 1 and first instance indication information 2 (first instance indication information 2 under first-type indication information 1). First indication information 3 corresponds to information interaction with logical function entity 1. Logical function entity 1 includes awareness of service 1. First indication information 3 is a combination of first-type indication information 2 and first instance indication information 1 (first instance indication information 1 under first-type indication information 2). First indication information 4 corresponds to information interaction with logical function entity 1. Logical function entity 1 includes awareness of service 2. First indication information 4 is a combination of first-type indication information 2 and first instance indication information 2 (first instance indication information 2 under first-type indication information 2).

[0127] Business / function / service type, for example, session management type, short message type, UE policy type, location / positioning type, perception type, AI type, core network business / function / service type.

[0128] Logical function entity type, for example, session management function type, short message function type, UE policy function type, location / positioning function type, perception function type, AI function type, core network logical function entity type.

[0129] The correspondence between the first-type indication information and the business / function / service / logical function entity type it indicates may be defined in a standard protocol. The first-type indication information may be one of the following: number, identifier, index, radio bearer, logical channel, transport channel, physical channel, message name / type, and information element.

[0130] The first instance indication information may be one of the following: number, identifier, index, radio bearer, logical channel, transport channel, and physical channel.

[0131] Note: It is not excluded that multiple first instance indication information corresponds to one logical functional entity.

[0132] Optionally, for the above two methods of the first indication information, the access network device may have the following situations when determining the first indication information:

[0133] For method 1, the access network device needs to allocate / configure the first indication information corresponding to the target information interaction. For method 2, one implementation is for the access network device to allocate / configure the first instance indication information in the first indication information corresponding to the target information interaction. The first type indication information can be predefined or preconfigured. Another implementation is for the access network device to separately allocate / configure the first type indication information and the second instance indication information in the first indication information corresponding to the target information interaction.

[0134] Optionally, for the above two methods of the first indication information, the access network device may indicate the first indication information to the first terminal device in the following situations:

[0135] For method one, the access network device indicates the first indication information corresponding to the target information interaction to the first terminal device. For method two, one implementation method is that the access network device indicates the first instance indication information in the first indication information corresponding to the target information interaction to the first terminal device. Another implementation method is that the access network device indicates the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction to the first terminal device. Yet another implementation method is that the access network device indicates the first type indication information in the first indication information to the first terminal device. Yet another implementation method is that the access network device instructs the first terminal device to allocate / configure the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction.

[0136] Similarly, for the above two methods of the first indication information, the first terminal device may have the following situations when determining the first indication information:

[0137] For method one, the first terminal device needs to allocate / configure the first indication information corresponding to the target information interaction. For method two, one implementation method is that the first terminal device allocates / configures the first instance indication information in the first indication information corresponding to the target information interaction. The first type indication information can be predefined or preconfigured. Another implementation method is that the first terminal device allocates / configures the first type indication information and the second instance indication information in the first indication information corresponding to the target information interaction, respectively.

[0138] Optionally, for the above two methods of the first indication information, the first terminal device may indicate the first indication information to the access network device in the following situations:

[0139] For method one, the first terminal device indicates the first indication information corresponding to the target information interaction to the access network device. For method two, one implementation method is that the first terminal device indicates the first instance indication information in the first indication information corresponding to the target information interaction to the access network device. Another implementation method is that the first terminal device indicates the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction to the access network device. Yet another implementation method is that the first terminal device indicates the first type indication information in the first indication information to the access network device. Yet another implementation method is that the first terminal device indicates to the access network device the allocation / configuration of the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction.

[0140] Optionally, depending on the entity that allocates / configures the first indication information, the first indication information may be determined in the following different ways:

[0141] Method 1: First indication information corresponding to the interaction of access network device allocation / configuration target information

[0142] The access network device allocates / configures the first indication information corresponding to the target information interaction, or the first instance indication information in the first indication information corresponding to the target information interaction, or the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction.

[0143] Method 2: The first terminal device allocates / configures the first indication information corresponding to the target information interaction

[0144] The first terminal device allocates / configures the first indication information corresponding to the target information interaction, or the first instance indication information in the first indication information corresponding to the target information interaction, or the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction.

[0145] The first terminal device sends the first indication information corresponding to the allocated / configured target information interaction, or the first instance indication information in the first indication information corresponding to the target information interaction, or the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction to the access network device.

[0146] Method 3: The access network device and the first terminal device allocate / configure the first indication information corresponding to the target information interaction

[0147] The first type of indication information in the first indication information corresponding to the interaction of the target information allocated / configured by the access network device, the first instance indication information in the first indication information corresponding to the interaction of the target information allocated / configured by the first terminal device, the first terminal device sends the first instance indication information in the first indication information corresponding to the interaction of the target information allocated / configured to the access network device.

[0148] Alternatively, the access network device allocates / configures the instance indication information in the first indication information corresponding to the target information interaction, and the first terminal device allocates / configures the first type indication information in the first indication information corresponding to the target information interaction, and the first terminal device sends the first type indication information in the first indication information corresponding to the target information interaction allocated / configured to the access network device.

[0149] It should be noted that, in the embodiment of the present disclosure, the first indication information corresponding to the target information interaction indicated by the access network device to the first terminal device may be indicated explicitly or implicitly. For example, the explicit indication is that the first terminal device indicates to the access network device that information interaction (target information interaction) of the target business or target function or target service is required, and the access network device indicates the first indication information corresponding to the target information interaction to the first terminal device. For example, the implicit indication is that the access network device sends the third information from the first logical function entity to the first terminal device, and indicates that the third information corresponds to the first indication information, and the third information belongs to the information interaction (target information interaction) of the target business or target function or target service, then the target information interaction corresponds to the first indication information.

[0150] The first terminal device instructs the access network device to initiate target information interaction, and indicates to the access network device first indication information corresponding to the target information interaction, and can indicate to the access network device in a single message or in separate messages. When indicating to the access network device in a single message, the message can also include relevant service information of the target information interaction.

[0151] When the first terminal device indicates the need for information interaction of the target business or target function or target service (target information interaction), and sends the relevant business information of the information interaction of the target business or target function or target service to the access network device, the access network device sends the relevant business information to the first logical function entity.

[0152] When the first logical function entity indicates that information interaction of a target service, target function, or target service (target information interaction) is required, and sends service information related to the information interaction of the target service, target function, or target service to the access network device, the access network device sends the related service information to the first terminal device. The access network device may send the related service information to the first terminal device and indicate the first indication information corresponding to the target information interaction to the first terminal device in one message or in different messages.

[0153] In the embodiment of the present disclosure, since a business / function / service information interaction between the UE and the network function is assigned a first indication message, the access network device can match the first indication message with the network function corresponding to the business / function / service, thereby being able to forward the relevant business information of the information interaction of the business / function / service to the corresponding network function. And the UE can also match the first indication message with the information interaction of the business / function / service, thereby being able to identify and process the relevant business information of the information interaction of the business / function / service. In addition, since the first indication message can correspond to different network function instances of the same network function, the problem of the UE interacting with multiple network functions of the same type at the same time can be solved.

[0154] The information transmission method provided by the embodiment of the present disclosure is that the access network device receives the first information sent by the first terminal device or the first logical function entity, wherein the first information is used to indicate the initiation of the target information interaction, thereby indicating the first indication information corresponding to the target information interaction to the first terminal device, and / or obtaining the first indication information corresponding to the target information interaction determined by the first terminal device, wherein the first indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the first logical function entity, and / or the first indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device. Therefore, by allocating the indication information of different information interactions, it is possible to avoid defining a special RRC information element or RRC message for each information interaction in the standard protocol to carry the message, and the protocol design is flexible. At the same time, different first indication information can be allocated to the information interaction of different network function instances of the same network function, thereby solving the problem of the UE interacting with multiple network functions of the same type at the same time.

[0155] In order to clearly illustrate the previous embodiment, the embodiment of the present disclosure provides another information transmission method. FIG4 is a flow chart of another information transmission method provided by the embodiment of the present disclosure.

[0156] Similarly, the information transmission method of the embodiments of the present disclosure is applied to an access network device. Optionally, the access network device can be any device in the RAN. As an example, the access network device can be any logical functional entity in the RAN, such as a network function, a logical node, or a logical unit.

[0157] Similarly, the logical functional entity can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, which is not limited in the embodiments of the present disclosure.

[0158] As shown in FIG4 , the information transmission method may include steps: 401 - 403 .

[0159] Step 401: Receive first information sent by a first terminal device or a first logical function entity.

[0160] Step 402: Indicate first indication information corresponding to the target information interaction to the first terminal device, and / or obtain first indication information corresponding to the target information interaction determined by the first terminal device.

[0161] It should be noted that the execution process of steps 401-402 can refer to the execution process of steps 301-302 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0162] Step 403: When the second information indicated by the first indication information is received from the first terminal device, the second information is sent to the first logical function entity corresponding to the target information interaction, and / or when the third information of the target information interaction is received from the first logical function entity, the third information indicated by the first indication information is sent to the first terminal device corresponding to the target information interaction.

[0163] It should be noted that, in the embodiment of the present disclosure, the access network device includes a routing function for forwarding relevant business information of the target information interaction to the corresponding first terminal device or first logical function entity. The first terminal device includes a routing marking function for indicating the first indication information corresponding to the target information interaction to the access network device. For uplink interaction information, the first terminal device generates relevant business information (second information) of the target information interaction, the first terminal device determines the first indication information corresponding to the target information interaction, and sends the second information indicated by the first indication information to the access network device (indicating that the second information corresponds to the first indication information). After receiving the second information indicated by the first indication information, the access network device sends the second information to the first logical function entity corresponding to the target information interaction. The first logical function entity processes the relevant business information (second information) of the target information interaction. For downlink interaction information, the first logical function entity generates relevant business information (third information) of the information interaction of the target business or target function or target service, and sends the third information to the access network device. After receiving the third information, the access network device sends the third information indicated by the first indication information to the first terminal device (indicating that the third information corresponds to the first indication information). The first terminal device receives the third information indicated by the first indication information and determines, based on the target information interaction corresponding to the first indication information, that the third information corresponds to the target information interaction. The first terminal device processes the relevant service information (third information) of the target information interaction. Optionally, the first terminal device may deliver the third information to a logical functional entity for processing the target information interaction. The logical functional entity for processing the target information interaction within the first terminal device processes the third information.

[0164] As a possible implementation method, when receiving second information indicated by first indication information sent by a first terminal device, the access network device may send the second information to the first logical function entity corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction, and / or, when receiving third information of target information interaction sent by the first logical function entity, the access network device may send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction.

[0165] Specifically, upon receiving second information indicated by first indication information sent by a first terminal device, the access network device may determine the target information interaction corresponding to the first indication information based on the correspondence between the first indication information and the target information interaction, and send the second information to the first logical function entity corresponding to the target information interaction. Upon receiving third information of the target information interaction sent by the first logical function entity, the access network device may determine the first indication information corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction, and send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction.

[0166] Optionally, before the access network device sends the second information to the first logical functional entity corresponding to the target information interaction, the access network device can also determine the first logical functional entity corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction and the correspondence between the target information interaction and the first logical functional entity.

[0167] It should be noted that in the embodiment of the present disclosure, after determining the first logical functional entity corresponding to the target information interaction, the access network device can forward the second information to the first logical functional entity when the first terminal device sends the relevant business information (second information) of the information interaction of the target business or target function or target service to the access network device.

[0168] It should be noted that in the embodiments of the present disclosure, if the first logical functional entity indicates that information interaction with a target business, target function, or target service (target information interaction) is required, that is, the access network device receives the first information sent by the first logical functional entity, the first logical functional entity may indicate to the access network device that the first terminal device is to perform the target information interaction with the first logical functional entity. Therefore, upon receiving the third information for target information interaction sent by the first logical functional entity, the access network device may directly send the third information indicated by the first indication information to the first terminal device. Optionally, the first logical functional entity may indicate that the target information interaction is to be performed with the first terminal device when sending the third information for target information interaction to the access network device.

[0169] In summary, when the first terminal device indicates the need for information interaction of the target business or target function or target service (target information interaction), and also sends the relevant business information (second information) of the information interaction of the target business or target function or target service to the access network device, the access network device can forward the second information to the first logical function entity after determining the first logical function entity corresponding to the target information interaction.

[0170] When the first logical function entity indicates the need for information interaction of the target business or target function or target service (target information interaction), and also sends relevant business information (third information) of the information interaction of the target business or target function or target service to the access network device, the access network device can send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction (when the first logical function entity indicates to the access network device that target information interaction is required, it will indicate to the access network device that the first terminal device is performing target information interaction with the first logical function entity) after determining the first indication information corresponding to the target information interaction.

[0171] In the information transmission method provided by the embodiments of the present disclosure, an access network device may, upon receiving second information indicated by first indication information sent by a first terminal device, send the second information to a first logical functional entity corresponding to a target information interaction, and / or, upon receiving third information of a target information interaction sent by the first logical functional entity, send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction. Thus, the access network device can forward service information related to the target information interaction to the corresponding first terminal device or first logical functional entity based on the first indication information.

[0172] In the present disclosure, the access network device may also determine the correspondence between the first indication information and the first logical function entity. This process is described below in conjunction with FIG. 5 .

[0173] FIG5 is a flow chart of another information transmission method provided by an embodiment of the present disclosure.

[0174] Similarly, the information transmission method of the embodiments of the present disclosure is applied to an access network device. Optionally, the access network device can be any device in the RAN. As an example, the access network device can be any logical functional entity in the RAN, such as a network function, a logical node, or a logical unit.

[0175] Similarly, the logical functional entity can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, which is not limited in the embodiments of the present disclosure.

[0176] As shown in FIG5 , the information transmission method may include steps: 501 - 504 .

[0177] Step 501: Receive first information sent by a first terminal device or a first logical function entity.

[0178] Step 502: Indicate first indication information corresponding to the target information interaction to the first terminal device, and / or obtain first indication information corresponding to the target information interaction determined by the first terminal device.

[0179] It should be noted that the execution process of steps 501-502 can refer to the execution process of steps 301-302 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0180] Step 503: Determine the correspondence between the first indication information and the first logical function entity.

[0181] In an embodiment of the present disclosure, the access network device may associate the first indication information corresponding to the target information interaction with the first logical functional entity corresponding to the target information interaction. Optionally, this association may be direct or indirect, and is not limited in this embodiment. For example, an indirect association may involve the first indication information corresponding to the target information interaction, and the target information interaction corresponding to the first logical functional entity. Accordingly, the access network device determines the correspondence between the first indication information and the target information interaction, and the correspondence between the target information interaction and the first logical functional entity.

[0182] Optionally, the access network device may store / apply the correspondence between the first indication information and the first logical functional entity. Alternatively, the access network device may store / apply the correspondence between the first indication information and the target information interaction, and the correspondence between the target information interaction and the first logical functional entity.

[0183] Optionally, a first logical function entity may correspond to a piece of first indication information on a one-to-one basis. For example, first logical function entity 1 corresponds to first indication information 1. First logical function entity 2 corresponds to first indication information 2. Optionally, a first logical function entity may correspond to multiple pieces of first indication information. For example, if multiple business / function / service information interactions correspond to one first logical function entity, and one business / function / service information interaction corresponds to one piece of first indication information, then a first logical function entity may correspond to multiple pieces of first indication information. For example, first logical function entity 1 corresponds to first indication information 1 and first indication information 2.

[0184] Step 504: When second information indicated by the first indication information is received from the first terminal device, the second information is sent to the first logical function entity corresponding to the target information interaction according to the correspondence between the first indication information and the first logical function entity, and / or, when third information of the target information interaction is received from the first logical function entity, the third information indicated by the first indication information is sent to the first terminal device corresponding to the target information interaction according to the correspondence between the first indication information and the first logical function entity.

[0185] For uplink interaction information, the first terminal device generates relevant service information (second information) for the target information interaction, determines first indication information corresponding to the target information interaction, and sends second information indicated by the first indication information to the access network device (indicating that the second information corresponds to the first indication information). After receiving the second information indicated by the first indication information, the access network device determines the first logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the first logical function entity, and sends the second information to the first logical function entity. The first logical function entity processes the relevant service information (second information) for the target information interaction. For downlink interaction information, the first logical function entity generates relevant service information (third information) for the information interaction of the target service, target function, or target service, and sends the third information to the access network device. After receiving the third information, the access network device determines the first indication information corresponding to the first logical function entity based on the correspondence between the first indication information and the first logical function entity, and sends the third information indicated by the first indication information to the first terminal device (indicating that the third information corresponds to the first indication information). The first terminal device receives the third information indicated by the first indication information and, based on the target information interaction corresponding to the first indication information, determines that the third information corresponds to the target information interaction. The first terminal device processes the relevant service information (third information) of the target information interaction. Optionally, the first terminal device may deliver the third information to a logical functional entity for processing the target information interaction. The logical functional entity for processing the target information interaction within the first terminal device processes the third information.

[0186] Among them, the access network device determines the first logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the first logical function entity, which can be determined directly or indirectly. Indirect determination is for example, the access network device determines the target information interaction corresponding to the first indication information based on the correspondence between the first indication information and the target information interaction, and then determines the first logical function entity corresponding to the target information interaction based on the correspondence between the target information interaction and the first logical function entity. The access network device determines the first indication information corresponding to the first logical function entity based on the correspondence between the first indication information and the first logical function entity, which can be determined directly or indirectly. Indirect determination is for example, the access network device determines the target information interaction corresponding to the first logical function entity based on the correspondence between the first logical function entity and the target information interaction, and then determines the first indication information corresponding to the target information interaction based on the correspondence between the target information interaction and the first indication information.

[0187] In the information transmission method provided by the embodiments of the present disclosure, an access network device determines a correspondence between first indication information and a first logical functional entity. Thus, upon receiving second information indicated by the first indication information from a first terminal device, the access network device transmits the second information to the first logical functional entity corresponding to the target information interaction based on the correspondence between the first indication information and the first logical functional entity. Furthermore, upon receiving third information of the target information interaction from the first logical functional entity, the access network device transmits the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction based on the correspondence between the first indication information and the first logical functional entity. Thus, based on the correspondence between the first indication information and the first logical functional entity, the access network device can forward service information related to the target information interaction to the corresponding first terminal device or first logical functional entity.

[0188] In the present disclosure, a second indication information may also be allocated for target information interaction. This process is described below with reference to FIG. 6 .

[0189] FIG6 is a flow chart of another information transmission method provided by an embodiment of the present disclosure.

[0190] Similarly, the information transmission method of the embodiments of the present disclosure is applied to an access network device. Optionally, the access network device can be any device in the RAN. As an example, the access network device can be any logical functional entity in the RAN, such as a network function, a logical node, or a logical unit.

[0191] Similarly, the logical functional entity can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, which is not limited in the embodiments of the present disclosure.

[0192] As shown in FIG6 , the information transmission method may include steps: 601 - 604 .

[0193] Step 601: Receive first information sent by a first terminal device or a first logical function entity.

[0194] Step 602: Indicate first indication information corresponding to the target information interaction to the first terminal device, and / or obtain first indication information corresponding to the target information interaction determined by the first terminal device.

[0195] It should be noted that the execution process of steps 601-602 can refer to the execution process of steps 301-302 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0196] Step 603: Send second indication information corresponding to the target information interaction to the first logical function entity, and / or obtain second indication information corresponding to the target information interaction determined by the first logical function entity.

[0197] The second indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the first logical function entity, and / or the second indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device.

[0198] It can also be understood that the second indication information is used to indicate relevant service information of target information interaction between the first logical function entity and the access network device.

[0199] In the embodiments of the present disclosure, the access network device may send second indication information corresponding to the target information interaction to the first logical function entity, and / or obtain the second indication information corresponding to the target information interaction determined by the first logical function entity. That is, the second indication information may be determined solely by the access network device, solely by the first logical function entity, or jointly by the access network device and the first logical function entity, and this is not limited in the embodiments of the present disclosure.

[0200] Optionally, the second indication information may be one of the following: number, identifier, index, radio bearer, logical channel, transport channel, physical channel.

[0201] It should be noted that in the embodiments of the present disclosure, a corresponding relationship also exists between target information interactions and second indication information. Optionally, a target information interaction may correspond one-to-one with one second indication information. For example, second indication information 1 corresponds to target information interaction 1. Second indication information 2 corresponds to target information interaction 2. Alternatively, multiple target information interactions may correspond to one second indication information. For example, target information interaction 1 and target information interaction 2 may both correspond to second indication information 1.

[0202] It should be noted that, in the embodiment of the present disclosure, the access network device sends the second indication information corresponding to the target information interaction to the first logical function entity, which can be an explicit indication or an implicit indication. For example, the first logical function entity indicates to the access network device that information interaction (target information interaction) of the target business or target function or target service is required, and the access network device indicates the second indication information corresponding to the target information interaction to the first logical function entity. For example, the access network device sends the second information from the first terminal device to the first logical function entity, and indicates that the second information corresponds to the second indication information, and the second information belongs to the information interaction (target information interaction) of the target business or target function or target service, then the target information interaction corresponds to the second indication information.

[0203] In the disclosed embodiments, since a business / function / service information exchange between a UE and a network function is assigned a second indication message, the network function can associate the second indication message with the business information related to the business / function / service information exchange, so as to identify and process the business information related to the business / function / service information exchange. In addition, since the second indication message can correspond to the information exchange of different businesses / functions / services of the same network function, the problem of the UE simultaneously interacting with the same network function for multiple businesses / functions / services can be solved.

[0204] As a possible implementation, the second indication information includes one indication information, so that the access network device can determine the second indication information corresponding to the target information interaction and indicate the second indication information corresponding to the target information interaction to the first logical function entity. Alternatively, the access network device receives the second indication information corresponding to the target information interaction indicated by the first logical function entity (in this case, the second indication information is determined independently by the first logical function entity).

[0205] As another possible implementation, the second indication information includes second type indication information and second instance indication information, so that the access network device may perform at least one of the following operations:

[0206] determining second type indication information in the second indication information corresponding to the target information interaction, and indicating the second type indication information corresponding to the target information interaction to the first logical function entity; or,

[0207] Determine second instance indication information in the second indication information corresponding to the target information interaction, and indicate the second instance indication information corresponding to the target information interaction to the first logical function entity; or,

[0208] determining the second type indication information and the second instance indication information in the second indication information corresponding to the target information interaction, and indicating the second type indication information and the second instance indication information corresponding to the target information interaction to the first logical function entity; or,

[0209] receiving second type indication information in second indication information corresponding to target information interaction indicated by the first logical function entity; or,

[0210] receiving second instance indication information in second indication information corresponding to the target information interaction indicated by the first logical function entity; or,

[0211] Receive second type indication information and second instance indication information in second indication information corresponding to the target information interaction indicated by the first logical function entity.

[0212] Optionally, the second indication information may correspond to one or more of the following: information interaction of a business / function / service, and information interaction of a logical functional entity within the UE. Furthermore, the second indication information may be per UE, per first logical functional entity, or both per UE and per first logical functional entity, which is not limited in the embodiments of the present disclosure.

[0213] It should be noted that, in the embodiment of the present disclosure, the second indication information may be the same as or different from the first indication information. When the second indication information is the same as the first indication information, the access network device determines the second indication information when it determines the first indication information.

[0214] The first logical function entity instructs the access network device to initiate target information interaction, and instructs the access network device to provide second indication information corresponding to the target information interaction, and can provide the indications to the access network device in a single message or in separate messages. When the indications are provided to the access network device in a single message, the message can also include relevant service information of the target information interaction.

[0215] Step 604: When the second information indicated by the first indication information is received from the first terminal device, the second information is sent to the first logical function entity corresponding to the target information interaction, and / or when the third information of the target information interaction is received from the first logical function entity, the third information indicated by the first indication information is sent to the first terminal device corresponding to the target information interaction.

[0216] It should be noted that the execution process of this step can refer to the execution process of step 403 in the above embodiment, the principle is the same, and it will not be repeated here. The execution process of this step can also refer to the execution process of step 504 in the above embodiment. Before this step, the access network device can also perform step 503, the principle is the same, and it will not be repeated here.

[0217] As a possible implementation method, when receiving second information indicated by first indication information sent by a first terminal device, the access network device may send the second information indicated by the second indication information to the first logical function entity corresponding to the target information interaction, and / or, when receiving third information indicated by the second indication information sent by the first logical function entity, send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction.

[0218] For uplink interaction information, the first terminal device generates relevant service information (second information) for the target information interaction, determines the first indication information corresponding to the target information interaction, and sends the second information indicated by the first indication information to the access network device (indicating that the second information corresponds to the first indication information). After receiving the second information indicated by the first indication information, the access network device sends the second information indicated by the second indication information to the first logical function entity corresponding to the target information interaction. The first logical function entity receives the second information indicated by the second indication information and, based on the target information interaction corresponding to the second indication information, determines the target information interaction corresponding to the second information. The first logical function entity processes the relevant service information (second information) for the target information interaction. For downlink interaction information, the first logical function entity generates relevant service information (third information) for the information interaction of the target service, target function, or target service, determines the second indication information corresponding to the target information interaction, and sends the third information indicated by the second indication information to the access network device (indicating that the third information corresponds to the second indication information). After receiving the third information indicated by the second indication information, the access network device sends the third information indicated by the first indication information to the first terminal device (indicating that the third information corresponds to the first indication information). The first terminal device receives the third information indicated by the first indication information and determines, based on the target information interaction corresponding to the first indication information, that the third information corresponds to the target information interaction. The first terminal device processes the relevant service information (third information) of the target information interaction. Optionally, the first terminal device may deliver the third information to a logical functional entity for processing the target information interaction. The logical functional entity for processing the target information interaction within the first terminal device processes the third information.

[0219] As a possible implementation method, when receiving second information indicated by first indication information sent by a first terminal device, the access network device may send the second information indicated by the second indication information to the first logical function entity corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction, and the correspondence between the second indication information and the target information interaction, and / or, when receiving third information indicated by the second indication information sent by the first logical function entity, the access network device may send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction, and the correspondence between the second indication information and the target information interaction.

[0220] Specifically, upon receiving second information indicated by first indication information sent by a first terminal device, the access network device may determine the target information interaction corresponding to the first indication information based on the correspondence between the first indication information and the target information interaction, determine the second indication information corresponding to the target information interaction based on the correspondence between the target information interaction and the second indication information, and send the second information indicated by the second indication information to the first logical function entity corresponding to the target information interaction. Upon receiving third information indicated by second indication information sent by a first logical function entity, the access network device may determine the target information interaction corresponding to the second indication information based on the correspondence between the target information interaction and the second indication information, determine the first indication information corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction, and send the third information indicated by the first indication information to the first terminal device.

[0221] It can also be understood that, upon receiving second information indicated by first indication information sent by a first terminal device, the access network device can determine the target information interaction corresponding to the first indication information based on the correspondence between the first indication information and the target information interaction, determine the <first logical function entity, second indication information> corresponding to the target information interaction based on the correspondence between the target information interaction and <first logical function entity, second indication information>, and send the second information indicated by the second indication information to the first logical function entity corresponding to the target information interaction. Upon receiving third information indicated by second indication information sent by a first logical function entity, the access network device can determine the target information interaction corresponding to <first logical function entity, second indication information> based on the correspondence between the target information interaction and <first logical function entity, second indication information>, determine the first indication information corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction, and send the third information indicated by the first indication information to the first terminal device.

[0222] It should be noted that the full text<X,Y> The symbol represents a combination of the two. For example, the above <first logical functional entity, second indication information> represents a combination of the first logical functional entity and the second indication information.

[0223] Optionally, before the access network device sends the second information indicated by the second indication information to the first logical functional entity corresponding to the target information interaction, the access network device can also determine the first logical functional entity corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction and the correspondence between the target information interaction and the first logical functional entity.

[0224] Optionally, before the access network device sends the second information indicated by the second indication information to the first logical function entity corresponding to the target information interaction, the access network device can also determine the first logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the first logical function entity.

[0225] In the information transmission method provided by the embodiments of the present disclosure, the access network device can send second indication information corresponding to the target information interaction to the first logical function entity, and / or obtain the second indication information corresponding to the target information interaction determined by the first logical function entity. As a result, the network function can associate the second indication information with the relevant business information of the information interaction of the business / function / service, so as to be able to identify and process the relevant business information of the information interaction of the business / function / service. At the same time, different second indication information can be allocated to the information interaction of different businesses / functions / services of the same network function, thereby solving the problem of the UE performing information interaction of multiple businesses / functions / services with the same network function at the same time.

[0226] It should be noted that, in the present disclosure, the access network device may also determine the correspondence between the second indication information and the first indication information when the second indication information is different from the first indication information. This process is described below with reference to FIG7 .

[0227] FIG7 is a flow chart of another information transmission method provided by an embodiment of the present disclosure.

[0228] Similarly, the information transmission method of the embodiments of the present disclosure is applied to an access network device. Optionally, the access network device can be any device in the RAN. As an example, the access network device can be any logical functional entity in the RAN, such as a network function, a logical node, or a logical unit.

[0229] Similarly, the logical functional entity can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, which is not limited in the embodiments of the present disclosure.

[0230] As shown in FIG. 7 , the information transmission method may include steps 701 - 705 .

[0231] Step 701: Receive first information sent by a first terminal device or a first logical function entity.

[0232] Step 702: Indicate first indication information corresponding to the target information interaction to the first terminal device, and / or obtain first indication information corresponding to the target information interaction determined by the first terminal device.

[0233] Step 703: Send second indication information corresponding to the target information interaction to the first logical function entity, and / or obtain second indication information corresponding to the target information interaction determined by the first logical function entity.

[0234] It should be noted that the execution process of steps 701-703 can refer to the execution process of steps 601-603 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0235] Step 704: When the second indication information is different from the first indication information, determine the correspondence between the second indication information and the first indication information.

[0236] In an embodiment of the present disclosure, the access network device can determine the correspondence between the second indication information and the first indication information when the second indication information is different from the first indication information. It can also be understood that the access network device matches the first indication information corresponding to the target information interaction with the second indication information corresponding to the target information interaction. Optionally, it can be directly corresponding or indirectly corresponding, and there is no limitation on this in the embodiment of the present disclosure. For example, the indirect correspondence is that the first indication information corresponds to the target information interaction, and the target information interaction corresponds to the second indication information. Accordingly, the access network device determines the correspondence between the first indication information and the target information interaction, and the correspondence between the target information interaction and the second indication information. In one way, the second indication information can be the first instance indication information in the first indication information.

[0237] Optionally, the access network device may store / apply the correspondence between the second indication information and the first indication information. Alternatively, the access network device may store / apply the correspondence between the first indication information and the target information interaction, and the correspondence between the target information interaction and the second indication information.

[0238] Optionally, a second indication message may correspond one-to-one with a first indication message. For example, second indication message 1 corresponds to first indication message 1. Second indication message 2 corresponds to first indication message 2. Optionally, a second indication message may correspond to multiple first indication messages. For example, if multiple business / function / service information interactions correspond to one second indication message, and one business / function / service information interaction corresponds to one first indication message, then one second indication message may correspond to multiple first indication messages. For example, second indication message 1 corresponds to first indication message 1 and first indication message 2.

[0239] Step 705: When the second information indicated by the first indication information is received from the first terminal device, the second information is sent to the first logical function entity corresponding to the target information interaction, and / or when the third information of the target information interaction is received from the first logical function entity, the third information indicated by the first indication information is sent to the first terminal device corresponding to the target information interaction.

[0240] It should be noted that the execution process of this step can refer to the execution process of step 604 in the above embodiment. The principles are the same and will not be repeated here.

[0241] As a possible implementation method, when receiving second information indicated by first indication information sent by a first terminal device, the access network device may send the second information indicated by the second indication information to the first logical function entity corresponding to the target information interaction based on the correspondence between the second indication information and the first indication information, and / or, when receiving third information indicated by the second indication information sent by the first logical function entity, the access network device may send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction based on the correspondence between the second indication information and the first indication information.

[0242] Specifically, upon receiving second information indicated by first indication information sent by a first terminal device, the access network device may determine the second indication information corresponding to the first indication information based on the correspondence between the first indication information and the second indication information, and send the second information indicated by the second indication information to the first logical function entity corresponding to the target information interaction. Upon receiving third information indicated by the second indication information sent by the first logical function entity, the access network device may determine the first indication information corresponding to the second indication information based on the correspondence between the second indication information and the first indication information, and send the third information indicated by the first indication information to the first terminal device.

[0243] Among them, the access network device determines that the second indication information corresponding to the first indication information based on the correspondence between the first indication information and the second indication information can be determined directly or indirectly. For example, indirect determination, the access network device determines the target information interaction corresponding to the first indication information based on the correspondence between the first indication information and the target information interaction, and then determines the second indication information corresponding to the target information interaction based on the correspondence between the target information interaction and the second indication information. The access network device determines that the first indication information corresponding to the second indication information based on the correspondence between the first indication information and the second indication information can be determined directly or indirectly. For example, indirect determination, the access network device determines the target information interaction corresponding to the second indication information based on the correspondence between the second indication information and the target information interaction, and then determines the first indication information corresponding to the target information interaction based on the correspondence between the target information interaction and the first indication information.

[0244] It can also be understood that, upon receiving second information indicated by the first indication information sent by the first terminal device, the access network device determines, based on the correspondence between the first indication information and the <first logical function entity, second indication information>, the <first logical function entity, second indication information> corresponding to the first indication information, and sends the second information indicated by the second indication information to the first logical function entity. Upon receiving third information indicated by the second indication information sent by the first logical function entity, the access network device determines, based on the correspondence between the first indication information and the <first logical function entity, second indication information>, the <first logical function entity, second indication information> corresponding to the <first logical function entity, second indication information>, and sends the third information indicated by the first indication information to the first terminal device.

[0245] For uplink interaction information, the first terminal device generates relevant service information (second information) for the target information interaction, determines first indication information corresponding to the target information interaction, and sends second information indicated by the first indication information to the access network device (indicating that the second information corresponds to the first indication information). After receiving the second information indicated by the first indication information, the access network device can determine the first logical function entity corresponding to the target information interaction and the second indication information corresponding to the target information interaction, and send the second information indicated by the second indication information to the first logical function entity.

[0246] For downlink interaction information, the first logical functional entity generates relevant service information (third information) for information interaction of a target service, target function, or target service. The first logical functional entity determines second indication information corresponding to the third information, and sends the third information and second indication information to the access network device (indicating that the third information corresponds to the second indication information). After receiving the third information indicated by the second indication information, the access network device may determine the first indication information corresponding to <first logical functional entity, second indication information>, and send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction.

[0247] If the second indication information is the same as the first indication information, that is, the same indication information, the routing control function of the access network device also includes the access network device indicating to the first logical function entity the second indication information (that is, the first indication information) corresponding to the target information interaction.

[0248] Optionally, for uplink interaction information, the access network device forwards relevant business information (e.g., second information) of business / function / service information interaction or information interaction of a logical functional entity within the terminal device to the first logical functional entity, and indicates to the first logical functional entity that the forwarded relevant business information corresponds to second indication information (i.e., first indication information). The first logical functional entity determines, based on the second indication information, the business / function / service information interaction corresponding to the relevant business information forwarded by the access network device.

[0249] Optionally, for downlink interaction information, the first logical function entity determines second indication information (i.e., first indication information) corresponding to the relevant service information (e.g., third information) of the target information interaction generated by the first logical function entity. The first logical function entity indicates to the access network device that the relevant service information of the target information interaction generated by the first logical function entity corresponds to the second indication information.

[0250] In the information transmission method provided by the embodiments of the present disclosure, an access network device determines the correspondence between the second indication information and the first indication information when the second indication information is different from the first indication information. Thus, upon receiving second information indicated by the first indication information from a first terminal device, the access network device sends the second information to the first logical function entity corresponding to the target information interaction based on the correspondence between the second indication information and the first indication information. Furthermore, upon receiving third information of the target information interaction from the first logical function entity, the access network device sends the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction based on the correspondence between the second indication information and the first indication information. Thus, based on the correspondence between the second indication information and the first indication information, the access network device can forward the relevant service information of the target information interaction to the corresponding first terminal device or first logical function entity.

[0251] It should be noted that the above embodiment describes the implementation process of the information transmission method from the perspective of the access network device. Below, in combination with Figure 8, a possible implementation method of the information transmission method is described from the perspective of the first terminal device. Figure 8 is a flow chart of another information transmission method provided by the embodiment of the present disclosure.

[0252] As shown in FIG8 , the information transmission method may include steps: 801 - 802 .

[0253] Step 801: Send first information to an access network device.

[0254] Among them, the first information is used to indicate the initiation of target information interaction, the target information interaction includes information interaction of target business or target function or target service, and the target information interaction is information interaction between the first terminal device and the first logical function entity.

[0255] In an embodiment of the present disclosure, the first terminal device may send first information for initiating target information interaction to the access network device, so as to inform the access network device that the first terminal device is to initiate target information interaction.

[0256] It should be noted that the rest of the execution process of this step can refer to the execution process of step 301 in the above embodiment. The principles are the same and will not be repeated here.

[0257] Step 802: Indicate first indication information corresponding to target information interaction to the access network device, and / or obtain first indication information corresponding to the target information interaction determined by the access network device.

[0258] Among them, the first indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the access network device, and / or the first indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device.

[0259] In the embodiments of the present disclosure, the first terminal device may indicate first indication information corresponding to the target information interaction to the access network device, and / or obtain the first indication information corresponding to the target information interaction determined by the access network device. That is, the first indication information may be determined solely by the access network device, solely by the first terminal device, or jointly by the access network device and the first terminal device, and this is not limited in the embodiments of the present disclosure.

[0260] It should be noted that the rest of the execution process of this step can refer to the execution process of step 302 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0261] The information transmission method provided by the embodiment of the present disclosure is that the first terminal device sends a first message to the access network device, wherein the first message is used to indicate the initiation of target information interaction, thereby indicating the first indication information corresponding to the target information interaction to the access network device, and / or obtaining the first indication information corresponding to the target information interaction determined by the access network device, wherein the first indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the first logical function entity, and / or the first indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device. Therefore, by allocating indication information for different information interactions, it is possible to avoid defining a special RRC information element or RRC message for each information interaction in the standard protocol to carry the message, and the protocol design is flexible. At the same time, different first indication information can be allocated to the information interaction of different network function instances of the same network function, thereby solving the problem of the UE interacting with multiple network functions of the same type at the same time.

[0262] In order to clearly illustrate the previous embodiment, the embodiment of the present disclosure provides another information transmission method. FIG9 is a flow chart of another information transmission method provided by the embodiment of the present disclosure.

[0263] Similarly, the information transmission method of the embodiment of the present disclosure is applied to the first terminal device.

[0264] As shown in FIG9 , the information transmission method may include steps: 901 - 903 .

[0265] Step 901: Send first information to an access network device.

[0266] It should be noted that the execution process of this step can refer to the execution process of step 801 in the above embodiment. The principles are the same and will not be repeated here.

[0267] Step 902: Indicate first indication information corresponding to target information interaction to the access network device, and / or obtain first indication information corresponding to the target information interaction determined by the access network device.

[0268] As a possible implementation, the first indication information includes an indication information, so that the first terminal device can determine the first indication information corresponding to the target information interaction and indicate the first indication information corresponding to the target information interaction to the access network device. Alternatively, the first indication information corresponding to the target information interaction indicated by the access network device is received (in this case, the first indication information is determined separately by the access network device).

[0269] As another possible implementation, the first indication information includes first type indication information and first instance indication information, so that the first terminal device can perform at least one of the following operations:

[0270] determining first type indication information in first indication information corresponding to target information interaction, and indicating the first type indication information corresponding to target information interaction to the access network device; or,

[0271] determining first instance indication information in the first indication information corresponding to the target information interaction, and indicating the first instance indication information corresponding to the target information interaction to the access network device; or,

[0272] determining first type indication information and first instance indication information in first indication information corresponding to target information interaction, and indicating the first type indication information and first instance indication information corresponding to the target information interaction to the access network device; or,

[0273] receiving first type indication information in first indication information corresponding to target information interaction determined by the access network device; or,

[0274] receiving first instance indication information in first indication information corresponding to target information interaction determined by the access network device; or,

[0275] Receive first type indication information and first instance indication information in first indication information corresponding to target information interaction determined by the access network device.

[0276] It should be noted that the rest of the execution process of this step can refer to the execution process of step 302 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0277] Step 903: Send second information indicated by the first indication information to the access network device, and / or receive third information indicated by the first indication information sent by the access network device.

[0278] In an embodiment of the present disclosure, after determining the first indication information, the first terminal device may send second information indicated by the first indication information to the access network device, so that the access network device forwards the second information to the first logical functional entity corresponding to the target information interaction based on the correspondence between the first indication information and the target information interaction. Furthermore, the first terminal device may receive third information indicated by the first indication information from the access network device. In this case, since the third information is indicated by the first indication information, the first terminal device may determine, based on the correspondence between the first indication information and the target information interaction, that the third information was sent by the first logical functional entity corresponding to the target information interaction.

[0279] Optionally, when the first terminal device receives third information indicated by first indication information sent by the access network device, it can determine the target information interaction corresponding to the third information based on the first indication information.

[0280] It should be noted that the rest of the execution process of this step can refer to the execution process of step 403 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0281] In the information transmission method provided by the embodiment of the present disclosure, the first terminal device can send the first information for indicating the initiation of target information interaction to the access network device, and / or obtain the first indication information corresponding to the target information interaction determined by the access network device, thereby sending the second information indicated by the first indication information to the access network device, and / or receiving the third information indicated by the first indication information sent by the access network device. Thus, the first terminal device can match the first indication information with the relevant business information of the target information interaction, so as to be able to identify and process the relevant business information of the target information interaction. At the same time, different first indication information can be assigned to the information interaction of different network function instances of the same network function, thereby solving the problem of the UE interacting with multiple network functions of the same type at the same time.

[0282] In the present disclosure, the first terminal device may forward the third information to a third logical function entity within the first terminal device. This process is described below in conjunction with FIG. 10 .

[0283] FIG10 is a flow chart of another information transmission method provided by an embodiment of the present disclosure.

[0284] Similarly, the information transmission method of the embodiment of the present disclosure is applied to the first terminal device.

[0285] As shown in FIG. 10 , the information transmission method may include steps 1001 - 1006 .

[0286] Step 1001: Send first information to an access network device.

[0287] Step 1002: Indicate first indication information corresponding to target information interaction to the access network device, and / or obtain first indication information corresponding to the target information interaction determined by the access network device.

[0288] Step 1003: Send second information indicated by the first indication information to the access network device, and / or receive third information indicated by the first indication information sent by the access network device.

[0289] It should be noted that the execution process of steps 1001-1003 can refer to the execution process of steps 901-903 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0290] Step 1004: Determine a third logical functional entity corresponding to target information interaction within the first terminal device.

[0291] In the embodiment of the present disclosure, the UE also includes a logical functional entity that performs information exchange of services / functions / services (which can also be understood as a logical functional entity that includes services / functions / services), and each logical functional entity in the UE performs one or more services / functions / services. For example, a logical functional entity for session management, a logical functional entity for perception, a logical functional entity for location / positioning functions, a logical functional entity for AI functions, a logical functional entity for short message functions, a logical functional entity for UE policy functions, a logical functional entity for user plane functions, and a logical functional entity for access management.

[0292] The relationship between the target information interaction and the third logical functional entity in the UE is specifically the same as the above-mentioned “relationship between the target information interaction and the first logical functional entity”.

[0293] Optionally, the first indication information may correspond to one or more of the following: information interaction of one or more businesses / functions / services, information interaction of a logical functional entity, and information interaction of a logical functional entity within the UE.

[0294] Step 1005: Determine the correspondence between the first indication information and the third logical function entity.

[0295] In an embodiment of the present disclosure, a first terminal device may associate first indication information corresponding to a target information interaction with a third logical functional entity corresponding to the target information interaction. Optionally, this association may be direct or indirect, and is not limited in this embodiment. For example, an indirect association may involve the first indication information corresponding to the target information interaction, and the target information interaction corresponding to the third logical functional entity. Accordingly, the first terminal device determines the correspondence between the first indication information and the target information interaction, and the correspondence between the target information interaction and the third logical functional entity.

[0296] Optionally, the first terminal device may store / apply the correspondence between the first indication information and the third logical functional entity. Alternatively, the first terminal device may store / apply the correspondence between the first indication information and the target information interaction, and the correspondence between the target information interaction and the third logical functional entity.

[0297] Optionally, a third logical functional entity may correspond one-to-one with one piece of first indication information. For example, third logical functional entity 1 corresponds to first indication information 1. Third logical functional entity 2 corresponds to first indication information 2. Optionally, a third logical functional entity may correspond to multiple pieces of first indication information. For example, if multiple business / function / service information interactions correspond to one third logical functional entity, and one business / function / service information interaction corresponds to one piece of first indication information, then one third logical functional entity may correspond to multiple pieces of first indication information. For example, third logical functional entity 1 corresponds to first indication information 1 and first indication information 2.

[0298] Step 1006: Send the third information to the third logical functional entity according to the correspondence between the first indication information and the third logical functional entity, or send the third information to the third logical functional entity corresponding to the target information interaction according to the correspondence between the first indication information and the target information interaction.

[0299] Optionally, when sending the third information to the third logical functional entity, since the third information is indicated by the first indication information, the first terminal device may, after determining the correspondence between the first indication information and the third logical functional entity, directly send the third information to the third logical functional entity based on the correspondence between the first indication information and the third logical functional entity. Alternatively, after determining the correspondence between the first indication information and the third logical functional entity, the first terminal device may, based on the correspondence between the first indication information and the target information interaction, send the third information to the third logical functional entity corresponding to the target information interaction.

[0300] In summary, in the embodiments of the present disclosure, the first terminal device includes not only the routing marking function but also the following routing control functions:

[0301] 1. The first terminal device determines a third logical function entity corresponding to target information interaction within the first terminal device;

[0302] Optionally, the access network device may indicate to the first terminal device that target information interaction is required, so that the first terminal device determines a third logical functional entity within the first terminal device corresponding to the target information interaction. Alternatively, the third logical functional entity within the first terminal device indicates to the first terminal device that target information interaction is required.

[0303] 2. The first terminal device determines first indication information corresponding to the target information interaction;

[0304] Optionally, the first terminal device may determine the first indication information, or the first type indication information in the first indication information, or the first instance indication information in the first indication information, or the first type indication information and the first instance indication information in the first indication information.

[0305] Optionally, the first terminal device may also receive first indication information determined by the access network device indicated by the access network device to the first terminal device, or first type indication information in the first indication information, or first instance indication information in the first indication information, or first type indication information and first instance indication information in the first indication information.

[0306] 3. The first terminal device determines the correspondence between the first indication information and the third logical function entity;

[0307] 4. The first terminal device instructs the access network device to perform first instruction information corresponding to target information interaction;

[0308] The first terminal device indicates to the access network device the first indication information determined by it, or the first type indication information in the first indication information, or the first instance indication information in the first indication information, or the first type indication information and the first instance indication information in the first indication information.

[0309] This step is optional.

[0310] The first terminal device also includes routing functions:

[0311] 5. The first terminal device receives the third information and the first indication information from the access network device, where the first indication information corresponds to the third information;

[0312] The access network device includes a routing marking function for indicating first indication information corresponding to the service / function / service-related information to the first terminal device. For downlink interaction information, the first logical function entity generates service information (third information) related to the information interaction of the target service, target function, or target service, and sends it to the access network device. Upon receiving the third information, the access network device may determine that the third information corresponds to the first indication information and send the third information indicated by the first indication information to the first terminal device.

[0313] 6. The first terminal device determines the third logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the third logical function entity, and forwards the third information to the third logical function entity.

[0314] The access network device includes a routing function for delivering business / function / service related information to the logical functional entity in the corresponding first terminal device. After the first terminal device receives the third information indicated by the first indication information, it can determine the third logical functional entity in the first terminal device corresponding to the first indication information, and send the third information to the third logical functional entity in the first terminal device. The routing function of the first terminal device can determine the third logical functional entity in the first terminal device corresponding to the first indication information directly or indirectly. For example, indirect determination is that the first terminal device determines the target business or target function or target service corresponding to the first indication information based on the correspondence between the first indication information and the target information interaction, and then determines the third logical functional entity in the first terminal device corresponding to the target business or target function or target service based on the correspondence between the target information interaction and the third logical functional entity in the first terminal device.

[0315] In the information transmission method provided by the embodiments of the present disclosure, a first terminal device determines a correspondence between first indication information and the third logical functional entity by determining the third logical functional entity corresponding to target information interaction within the first terminal device. The device then sends third information to the third logical functional entity based on the correspondence between the first indication information and the third logical functional entity, or sends the third information to the third logical functional entity corresponding to the target information interaction based on the correspondence between the first indication information and the third logical functional entity. Thus, the first terminal device can send the third information to the third logical functional entity corresponding to the target information interaction based on the correspondence between the first indication information and the third logical functional entity, or the correspondence between the first indication information and the target information interaction.

[0316] It should be noted that, in the present disclosure, the first terminal device may also determine the first indication information without sending the first information for instructing to initiate target information interaction to the access network device. This process is described below with reference to FIG11 .

[0317] FIG11 is a flow chart of another information transmission method provided by an embodiment of the present disclosure.

[0318] As shown in FIG11 , the information transmission method may include step: 1101 .

[0319] Step 1101: indicate first indication information corresponding to target information interaction to an access network device, and / or obtain first indication information corresponding to target information interaction determined by the access network device.

[0320] The target information interaction includes information interaction of a target business or a target function or a target service, and the target information interaction is information interaction between the first terminal device and the first logical function entity.

[0321] It should be noted that the explanation of "target information interaction", "first logical functional entity", "target business or target function or target service" in this step can be found in the description of step 301 in the above embodiment and will not be repeated here.

[0322] Among them, the first indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the access network device, and / or the first indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device.

[0323] In the embodiments of the present disclosure, the first terminal device may indicate first indication information corresponding to the target information interaction to the access network device, and / or obtain the first indication information corresponding to the target information interaction determined by the access network device. That is, the first indication information may be determined solely by the access network device, solely by the first terminal device, or jointly by the access network device and the first terminal device, and this is not limited in the embodiments of the present disclosure.

[0324] It should be noted that the rest of the execution process of this step can refer to the execution process of step 302 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0325] The information transmission method provided by the embodiment of the present disclosure is that the first terminal device sends a first message to the access network device, wherein the first message is used to indicate the initiation of target information interaction, thereby indicating the first indication information corresponding to the target information interaction to the access network device, and / or obtaining the first indication information corresponding to the target information interaction determined by the access network device, wherein the first indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the first logical function entity, and / or the first indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device. Therefore, by allocating indication information for different information interactions, it is possible to avoid defining a special RRC information element or RRC message for each information interaction in the standard protocol to carry the message, and the protocol design is flexible. At the same time, different first indication information can be allocated to the information interaction of different network function instances of the same network function, thereby solving the problem of the UE interacting with multiple network functions of the same type at the same time.

[0326] Optionally, in the present disclosure, the first terminal device may also determine the first indication information, send the second information indicated by the first indication information to the access network device, and / or receive the third information indicated by the first indication information sent by the access network device without sending the first information for initiating target information interaction to the access network device. This process is described below with reference to Figure 12.

[0327] FIG12 is a flow chart of another information transmission method provided in an embodiment of the present disclosure.

[0328] As shown in FIG12 , the information transmission method may include steps: 1201 - 1202 .

[0329] Step 1201: indicate first indication information corresponding to target information interaction to an access network device, and / or obtain first indication information corresponding to target information interaction determined by the access network device.

[0331] Step 1202: Send second information indicated by first indication information to the access network device, and / or receive third information indicated by the first indication information sent by the access network device.

[0332] It should be noted that the execution process of this step can refer to the execution process of step 903 in the above embodiment. The principles are the same and will not be repeated here.

[0333] The information transmission method provided by the embodiment of the present disclosure can, when sending the first information for indicating the initiation of target information interaction to the access network device, indicate the first indication information corresponding to the target information interaction to the access network device, and / or obtain the first indication information corresponding to the target information interaction determined by the access network device, thereby sending the second information indicated by the first indication information to the access network device, and / or receiving the third information indicated by the first indication information sent by the access network device. Thus, the first terminal device can match the first indication information with the relevant business information of the target information interaction, so as to be able to identify and process the relevant business information of the target information interaction. At the same time, different first indication information can be assigned to the information interaction of different network function instances of the same network function, thereby solving the problem of the UE interacting with multiple network functions of the same type at the same time.

[0334] The following describes a possible implementation of an information transmission method from the perspective of a first logical functional entity in conjunction with FIG13 . FIG13 is a flow chart of another information transmission method provided by an embodiment of the present disclosure.

[0335] As shown in FIG13 , the information transmission method may include step: 1301 .

[0340] In an embodiment of the present disclosure, the first logical function entity may send first information for instructing to initiate target information interaction to the access network device, so as to inform the access network device that the first logical function entity is to initiate target information interaction.

[0341] It should be noted that when the first logical function entity sends the first information for initiating target information interaction to the access network device, it will indicate to the access network device that the first terminal device is performing target information interaction with the first logical function entity.

[0342] It should be noted that the rest of the execution process of this step can refer to the execution process of step 301 in the above embodiment. The principles are the same and will not be repeated here.

[0343] In the information transmission method provided by the embodiment of the present disclosure, the first logical function entity can send first information to the access network device, wherein the first information is used to indicate the initiation of target information interaction, the target information interaction includes information interaction of target business or target function or target service, the target information interaction is the information interaction between the first terminal device and the first logical function entity, the target information interaction corresponds to the first indication information, wherein the first indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the first logical function entity, and / or the first indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device. Therefore, by allocating indication information for different information interactions, it is possible to avoid defining a special RRC information element or RRC message for each information interaction in the standard protocol to carry the message, and the protocol design is flexible. At the same time, different first indication information can be allocated to the information interaction of different network function instances of the same network function, thereby solving the problem of the UE interacting with multiple network functions of the same type at the same time.

[0344] It should be noted that, in the present disclosure, the first logical function entity may further send third information for target information interaction to the access network device and / or receive second information for target information interaction sent by the access network device to implement target information interaction with the first terminal device. This process is described below with reference to FIG14 .

Furthermore, the first logical functional entity may receive the second information of the target information interaction sent by the access network device from the first terminal device.

[0352] It should be noted that the rest of the execution process of this step can refer to the execution process of step 403 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0353] In the information transmission method provided by the embodiments of the present disclosure, after sending first information to an access network device, a first logical function entity may send third information for target information interaction to the access network device and / or receive second information for target information interaction sent by the access network device. This enables target information interaction between the first logical function entity and the first terminal device.

[0354] In the present disclosure, a second indication information may also be allocated for target information interaction. This process will be described below from the perspective of the first logical functional entity in conjunction with FIG. 15 .

[0355] FIG15 is a flow chart of another information transmission method provided in an embodiment of the present disclosure.

[0359] Step 1502: Indicate second indication information corresponding to the target information interaction to the access network device, and / or obtain second indication information corresponding to the target information interaction determined by the access network device.

[0360] In the embodiments of the present disclosure, the first logical functional entity may indicate second indication information corresponding to the target information interaction to the access network device, and / or obtain the second indication information corresponding to the target information interaction determined by the access network device. That is, the second indication information may be determined solely by the access network device, solely by the first logical functional entity, or jointly by the access network device and the first logical functional entity, and this is not limited in the embodiments of the present disclosure.

[0361] It should be noted that the rest of the execution process of this step can refer to the execution process of step 603 in the above embodiment, and the principles are the same, so they will not be repeated here.

And / or, the first logical function entity may receive the second information indicated by the second indication information sent by the access network device.

[0364] Optionally, when receiving the second information indicated by the second indication information sent by the access network device, the first logical function entity may determine, based on the first indication information, that the second information corresponds to the target information interaction.

[0365] It should be noted that the other execution processes of this step can refer to the execution process of step 604 in the above embodiment. The principles are the same and will not be repeated here.

[0366] In the information transmission method provided by the embodiment of the present disclosure, the first logical function entity can, when sending first information for indicating the initiation of target information interaction to the access network device, indicate second indication information corresponding to the target information interaction to the access network device, and / or obtain the second indication information corresponding to the target information interaction determined by the access network device, thereby sending third information indicated by the second indication information to the access network device, and / or receiving the second information indicated by the second indication information sent by the access network device. Thus, the first logical function entity can match the second indication information with the relevant business information of the target information interaction so as to be able to identify and process the relevant business information of the target information interaction. At the same time, different second indication information can be allocated to the information interaction of different businesses / functions / services of the same network function, thereby solving the problem of the UE performing information interaction of multiple businesses / functions / services with the same network function at the same time.

[0367] It should be noted that, in the present disclosure, the first logical function entity may also determine the second indication information without sending the first information for instructing to initiate target information interaction to the access network device. This process is described below with reference to FIG16 .

[0370] Step 1601: Indicate second indication information corresponding to target information interaction to the access network device, and / or obtain second indication information corresponding to the target information interaction determined by the access network device.

[0371] The target information interaction includes information interaction of a target business or a target function or a target service, and the target information interaction is information interaction between the first terminal device and the first logical function entity.

[0372] It should be noted that the explanation of "target information interaction", "first logical functional entity", "target business or target function or target service" in this step can be found in the description of step 301 in the above embodiment and will not be repeated here.

That is, the second indication information may be determined solely by the access network device, solely by the first logical functional entity, or jointly by the access network device and the first logical functional entity, and this is not limited in the embodiments of the present disclosure.

[0375] It should be noted that the rest of the execution process of this step can refer to the execution process of step 603 in the above embodiment, and the principles are the same, so they will not be repeated here.

[0376] In the information transmission method provided by the embodiment of the present disclosure, the first logical function entity can indicate the second indication information corresponding to the target information interaction to the access network device, and / or obtain the second indication information corresponding to the target information interaction determined by the access network device, wherein the target information interaction includes the information interaction of the target business or target function or target service, and the target information interaction is the information interaction between the first terminal device and the first logical function entity, wherein the second indication information is used to indicate the second information of the target information interaction sent by the first terminal device to the first logical function entity, and / or the second indication information is used to indicate the third information of the target information interaction sent by the first logical function entity to the first terminal device. In this way, different second indication information can be allocated to the information interaction of different businesses / functions / services of the same network function, thereby solving the problem of the UE performing information interaction of multiple businesses / functions / services with the same network function at the same time.

[0377] Optionally, in the present disclosure, the first logical function entity may determine second indication information, send third information indicated by the second indication information to the access network device, and / or receive second information indicated by the second indication information sent by the access network device, without sending first information indicating initiation of target information interaction to the access network device. This process is described below with reference to FIG17 .

[0378] FIG17 is a flow chart of another information transmission method provided in an embodiment of the present disclosure.

[0379] As shown in FIG. 17 , the information transmission method may include steps: 1701 - 1702 .

[0380] Step 1701: Indicate second indication information corresponding to target information interaction to the access network device, and / or obtain second indication information corresponding to the target information interaction determined by the access network device.

[0381] It should be noted that the execution process of this step can refer to the execution process of step 1601 in the above embodiment. The principles are the same and will not be repeated here.

Thus, the first logical function entity can match the second indication information with the relevant business information of the target information interaction so as to be able to identify and process the relevant business information of the target information interaction. At the same time, different second indication information can be allocated to the information interaction of different businesses / functions / services of the same network function, thereby solving the problem of the UE performing information interaction of multiple businesses / functions / services with the same network function at the same time.

[0385] In order to clearly illustrate the above embodiment, an example is now given for illustration.

[0386] FIG18 is a flow chart of an information transmission method in a scenario provided by an embodiment of the present disclosure.

[0387] It should be noted that the "access network" in Figure 18 refers to the access network equipment in various embodiments of the present disclosure. The actions of the access network equipment can be performed by one or more logical functional entities in the access network. The "UE" in Figure 18 refers to the first terminal device in various embodiments of the present disclosure. The "target logical functional entity" in Figure 18 refers to the first logical functional entity in various embodiments of the present disclosure.

[0388] With respect to the flowchart shown in FIG18 , there are the following embodiments:

[0389] Example 1:

[0390] The UE indicates to the access network that target information exchange is required.

[0391] 1) The UE indicates to the access network that it needs to exchange target information, and the access network determines the target logical function entity for this exchange. For example, the target information exchange required by the UE is the exchange of session management-related information for session 1. The UE indicates to the access network that it needs to exchange session-related information, and the access network determines the target logical function entity to be, for example, SMF1.

[0392] 2) The access network determines the first indication information corresponding to the target information interaction, including: the access network allocates the first indication information corresponding to the target information interaction. For example, the access network allocates the first indication information corresponding to the session management related information interaction of session 1 as 001.

[0393] 3) The access network determines the correspondence between the first indication information and the target logical function entity. For example, the access network determines that 001 corresponds to SMF1.

[0394] 4) The access network indicates to the UE that the target information interaction corresponds to the first indication information. For example, the access network indicates to the UE that the session management related information interaction of session 1 corresponds to the first indication information 001.

[0395] 5) The UE determines that the target information interaction corresponds to the first indication information. For example, the UE determines that the session management related information interaction of session 1 corresponds to 001.

[0396] 6) The UE determines that the target logical function entity within the UE corresponding to the target information interaction corresponds to the first indication information. For example, the UE determines that the target logical function entity within the UE corresponding to the session management related information interaction of session 1 is, for example, 001 corresponding to processing entity 1.

[0397] 7) The UE generates second information for target information interaction. The UE determines that the second information corresponds to the first indication information corresponding to the target information interaction. The UE sends second information to the access network, indicating that the second information corresponds to the first indication information. For example, the UE needs to interact with session management-related information for session 1. The UE generates second information for interaction with session management-related information for session 1. Based on the number 001 corresponding to the session management-related information interaction for session 1, the UE determines that the second information corresponds to 001. The UE sends the second information to the access network, indicating that the second information corresponds to 001.

[0398] 8) The access network determines the target logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the target logical function entity, and forwards the second information corresponding to the first indication information to the target logical function entity. For example, the access network determines that 001 corresponds to SMF1 and forwards the second information corresponding to 001 to SMF1.

[0399] 9) The target logical function entity generates third information for target information exchange and sends the third information to the access network. For example, if SMF1 needs to exchange session management related information for session 1 with UE, SMF1 generates third information for session management related information exchange and sends it to the access network.

[0400] 10) The access network determines the first indication information corresponding to the target logical function entity, and forwards the third information to the UE, indicating that the third information corresponds to the first indication information. For example, the access network determines that SMF1 corresponds to 001, and forwards the third information to the UE, indicating that the third information corresponds to 001.

[0401] 11) The UE determines the target logical function entity within the UE corresponding to the first indication information, and delivers the third information to the target logical function entity within the UE. For example, the UE determines that 001 corresponds to processing entity 1 within the UE, and delivers the third information to processing entity 1 within the UE.

[0402] Optionally, the UE may also need to perform session management-related information interaction, with the target information interaction being session 2. The UE indicates to the access network that it needs to perform session management-related information interaction, and the access network determines the target logical function entity, for example, SMF2. The access network assigns first indication information 002 corresponding to the session management-related information interaction for session 2. The access network determines that the first indication information 002 corresponds to the target logical function entity, SMF2. The access network indicates to the UE that the session management-related information interaction for session 2 corresponds to the first indication information 002. The UE determines that the session management-related information interaction for session 2 corresponds to the first indication information 002. The UE determines that the target logical function entity within the UE, for example, processing entity 1, corresponds to the first indication information 002. The UE generates second information for the session management-related information interaction for session 2. The UE determines that the second information corresponds to the first indication information 002 corresponding to the session management-related information interaction for session 2. The UE sends second information to the access network, indicating that the second information corresponds to the first indication information 002. The access network determines the target logical function entity SMF2 corresponding to the first indication information 002 and forwards the second information corresponding to the first indication information 002 to the target logical function entity SMF2. The target logical function entity SMF2 generates third information for the exchange of session management-related information for session 2 and sends the third information to the access network. The access network determines the first indication information 002 corresponding to the target logical function entity SMF2 and forwards the third information to the UE, indicating that the third information corresponds to the first indication information 002. The UE determines that the first indication information 002 corresponds to processing entity 1 within the UE and delivers the third information to processing entity 1 within the UE.

[0403] Optionally, the UE may also need to perform target information interaction, namely, perception-related information interaction. The UE indicates to the access network that it needs to perform perception-related information interaction, and the access network determines the target logical function entity, for example, SF1. The access network assigns first indication information corresponding to the perception-related information interaction as 004. The access network determines that the first indication information 004 corresponds to the target logical function entity SF1. The access network instructs the UE to perform perception-related information interaction, corresponding to the first indication information 004. The UE determines that the perception-related information interaction corresponds to the first indication information 004. The UE determines that the target logical function entity within the UE, for example, processing entity 2, corresponds to the first indication information 004. The UE generates second information for the perception-related information interaction. The UE determines that the second information corresponds to the first indication information 004 for the perception-related information interaction. The UE sends second information to the access network, indicating that the second information corresponds to the first indication information 004. The access network determines that the target logical function entity SF1 corresponds to the first indication information 004 and forwards the second information corresponding to the first indication information 004 to SF1. The target logical function entity SF1 generates eighth information corresponding to the perception-related information interaction and sends the eighth information to the access network. The access network determines the first indication information 004 corresponding to the target logical function entity SF1, and forwards the eighth information to the UE, indicating that the eighth information corresponds to the first indication information 004. The UE determines the processing entity 2 within the UE corresponding to the first indication information 004, and delivers the eighth information to the processing entity 2 within the UE.

[0404] Example 2:

[0405] Multiple business / function / service-related information interactions correspond to one first indication message. For example, the session management-related information interactions of session 1 and session 3 both correspond to logical function entity SMF1. The session management-related information interactions of session 1 and session 3 both correspond to first indication information 001.

[0406] 1) The UE indicates to the access network that it needs to exchange target information, and the access network determines a target logical function entity for the target information exchange; the target information exchange required by the UE is, for example, the exchange of session management-related information for session 3. The UE indicates to the access network that it needs to exchange session-related information, and the access network determines the target logical function entity to be, for example, SMF1.

[0407] 2) The access network determines the first indication information corresponding to the target information interaction, including: the access network determines that the first indication information corresponding to the target information interaction is the first indication information corresponding to the target logical function entity. For example, the first indication information corresponding to the target logical function entity SMF1 is 001, and the access network determines that the first indication information corresponding to the target information interaction is 001.

[0408] 3) Same as 4) in Example 1.

[0409] 4) The UE determines that the target information interaction corresponds to the first indication information. For example, the UE determines that the session management related information interaction of session 3 corresponds to 001.

[0410] 5) The UE determines that the target logical function entity within the UE corresponding to the target information interaction corresponds to the first indication information. For example, the UE determines that the target logical function entity within the UE corresponding to the session management related information interaction of session 3 is, for example, 001 corresponding to processing entity 1.

[0411] 6) The UE generates second information for target information exchange. The UE determines that the second information corresponds to the first indication information corresponding to the target information exchange. The UE sends second information to the access network, indicating the first indication information corresponding to the second information. For example, the UE needs to exchange information related to session management for session 3. The UE generates second information related to session management for session 3. Based on the number 001 corresponding to session management for session 3, the UE determines that the second information corresponds to 001. The UE sends the second information to the access network, indicating that the second information corresponds to 001.

[0412] 7) The access network determines the target logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the target logical function entity, and forwards the second information corresponding to the first indication information to the target logical function entity. For example, the access network determines that 001 corresponds to SMF1 and forwards the third information corresponding to 001 to SMF1.

[0413] 8) The target logical function entity generates the third information for target information exchange and sends the third information to the access network. For example, SMF1 needs to exchange session management related information for session 3 with UE. SMF1 generates the third information related to session management of session 3 and sends it to the access network.

[0414] 9) The access network determines the first indication information corresponding to the target logical function entity, and forwards the third information to the UE, indicating that the third information corresponds to the first indication information. For example, the access network determines 001 corresponding to SMF1, and forwards the second information to the UE, indicating that the second information corresponds to 001.

[0415] 10) The UE determines the target logical functional entity within the UE corresponding to the first indication information, and delivers the third information to the target logical functional entity within the UE. For example, the UE determines that the target logical functional entity within the UE corresponding to 001 is, for example, processing entity 1, and delivers the third information to processing entity 1 within the UE.

[0416] The second embodiment can be combined with the first embodiment.

[0417] Example 3:

[0418] The logical function entity obtains second indication information.

[0419] 1)-2) are the same as 1)-2) in Example 1.

[0420] 3) The access network determines the second indication information corresponding to the target information interaction. For example, the access network assigns the second indication information corresponding to the session management related information interaction of session 1 to be 01.

[0421] 4) The access network determines the correspondence between the first indication information and the target logical function entity. For example, the access network determines that 001 corresponds to SMF1. The access network also determines the correspondence between the first indication information and the second indication information. For example, the access network determines that 001 corresponds to 01. It can also be understood that the access network determines the correspondence between the first indication information and <target logical function entity, second indication information>. For example, the access network determines that 001 corresponds to<SMF1,01> correspond.

[0422] 5)-8) are the same as 4)-7) in Example 1.

[0423] 9) The access network determines the target logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the target logical function entity, and forwards the second information corresponding to the first indication information to the target logical function entity. For example, the access network determines that 001 corresponds to SMF1 and forwards the second information corresponding to 001 to SMF1. The access network also determines the second indication information corresponding to the first indication information based on the correspondence between the first indication information and the second indication information, and indicates to the target logical function entity that the second information corresponds to the second indication information. For example, the access network determines that 001 corresponds to the second indication information 01 and indicates to SMF1 that the second information corresponds to 01.

[0424] It can also be understood that the access network determines the <target logical function entity, second indication information> corresponding to the first indication information based on the correspondence between the first indication information and the <target logical function entity, second indication information>, and forwards the second information to the target logical function entity, indicating that the second information corresponds to the second indication information. For example, the access network determines that 001 corresponds to<SMF1,01> , forward the second information to SMF1, indicating that the second information corresponds to 01.

[0425] 10) The target logical function entity determines that the target information interaction corresponding to the second information corresponds to the second indication information. For example, SMF1 determines that the session management related information interaction of session 1 corresponding to the second information corresponds to 01.

[0426] 11) The target logical function entity generates third information for target information exchange. The target logical function entity determines that the third information corresponds to the second indication information corresponding to the target information exchange. The target logical function entity sends the third information to the access network, indicating that the third information corresponds to the second indication information. For example, SMF1 needs to exchange session management-related information for session 1 with the UE. SMF1 generates third information for session management-related information exchange for session 1. Based on the value 01 corresponding to the session management-related information exchange for session 1, SMF1 determines that the third information corresponds to 01. SMF1 sends the third information to the access network, indicating that the third information corresponds to 01.

[0427] 12) The access network determines the first indication information corresponding to the <target logical function entity, the second indication information>, and forwards the third information to the UE, indicating that the third information corresponds to the first indication information.<SMF1,01> Corresponding to 001, forwarding the third information to the UE, indicating that the third information corresponds to 001.

Optionally, the access network sends the UE third information related to the target information interaction. For example, the access network sends the UE third information related to the measurement report-related information interaction of data 1. The access network may also indicate to the UE the type of target service, target function, or target service corresponding to the target information interaction.

[0439] 5) The UE determines the target logical functional entity within the UE corresponding to the target information interaction. The UE may determine the target logical functional entity within the UE corresponding to the target information interaction that matches the type of the target service or target function or target service corresponding to the target information interaction. For example, the UE determines that the measurement report related information interaction of data 1 corresponds to the processing entity 1 within the UE. Optionally, the UE delivers the third information of the target information interaction to the target logical functional entity within the UE. For example, the UE delivers the third information of the measurement report related information interaction of data 1 to the processing entity 1 within the UE. The UE determines that the target logical functional entity within the UE corresponds to the first indication information. For example, the UE determines that the processing entity 1 within the UE corresponds to 001.

[0440] 6) The UE determines that the target information interaction corresponds to the first indication information. The UE may determine that the target information interaction corresponding to the third information corresponds to the first indication information. For example, the UE determines that the measurement report related information interaction of data 1 corresponds to 001.

[0441] 7) The UE generates second information for target information exchange. The UE determines that the second information corresponds to the first indication information corresponding to the target information exchange. The UE sends second information to the access network, indicating that the second information corresponds to the first indication information. For example, the UE needs to exchange measurement report-related information for data 1. The UE generates second information for measurement report-related information exchange for data 1. Based on the value 001 corresponding to the measurement report-related information exchange for data 1, the UE determines that the second information corresponds to 001. The UE sends second information to the access network, indicating that the second information corresponds to 001.

[0442] 8) The access network determines the target logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the target logical function entity, and forwards the second information corresponding to the first indication information to the target logical function entity. For example, the access network determines that 001 corresponds to logical function entity 1 and forwards the second information corresponding to 001 to logical function entity 1.

[0443] 9) The target logical function entity generates new third information for target information exchange and sends the new third information to the access network. For example, logical function entity 1 needs to exchange measurement report related information of data 1 with the UE. Logical function entity 1 generates new third information for measurement report related information exchange of data 1 and sends it to the access network.

[0444] 10) The access network determines the first indication information corresponding to the target logical function entity, and forwards new third information to the UE, indicating that the new third information corresponds to the first indication information. For example, the access network determines 001 corresponding to logical function entity 1, and forwards new third information to the UE, indicating that the new third information corresponds to 001.

[0445] 11) The UE determines the target logical function entity within the UE corresponding to the first indication information, and delivers the new third information to the target logical function entity within the UE. For example, the UE determines the processing entity 1 within the UE corresponding to 001, and delivers the new third information to the processing entity 1 within the UE.

[0446] Optionally, another target logical function entity, namely, logical function entity 2, may need to exchange target information with the UE for measurement reporting of data 2. Logical function entity 2 indicates to the access network that it needs to exchange measurement reporting-related information for data 2 with the UE. The access network determines that the target logical function entity is logical function entity 2. Logical function entity 2 sends third information for the exchange of measurement reporting-related information for data 2 to the access network. The access network assigns first indication information corresponding to the exchange of measurement reporting-related information for data 2 as 002. The access network determines that first indication information 002 corresponds to logical function entity 2. The access network indicates to the UE that the exchange of measurement reporting-related information for data 2 corresponds to first indication information 002. The access network sends third information for the exchange of measurement reporting-related information for data 2 to the UE. The UE determines that the target logical function entity within the UE for the exchange of measurement reporting-related information for data 2 is, for example, processing entity 1. The UE determines that processing entity 1 within the UE corresponds to first indication information 002. The UE determines that the exchange of measurement reporting-related information for data 2 corresponds to first indication information 002. The UE generates second information for the exchange of measurement reporting-related information for data 2. The UE determines that the second information corresponds to the first indication information 002 corresponding to the exchange of measurement reporting related information for data 2. The UE sends the second information to the access network, indicating that the second information corresponds to the first indication information 002. The access network determines that the logical function entity 2 corresponds to the first indication information 002 and forwards the second information corresponding to the first indication information to the logical function entity 2. The logical function entity 2 generates new third information for the exchange of measurement reporting related information for data 2 and sends the new third information to the access network. The access network determines that the first indication information 002 corresponds to the logical function entity 2 and forwards the new third information to the UE, indicating that the new third information corresponds to the first indication information 002. The UE determines that the target logical function entity within the UE corresponding to the first indication information 002 is, for example, processing entity 1, and delivers the new third information to processing entity 1 within the UE.

[0447] Optionally, logical function entity 1 needs to exchange target information with the UE, specifically measurement reporting-related information for data 3. Logical function entity 1 sends third information for the measurement reporting-related information exchange for data 3 to the access network. The access network determines the first indication information 001 corresponding to logical function entity 1 and forwards third information to the UE, indicating that the third information corresponds to the first indication information 001. The UE determines the target logical function entity within the UE corresponding to the first indication information and delivers the third information to the target logical function entity within the UE. For example, the UE determines the processing entity 1 within the UE corresponding to 001 and delivers the third information to the processing entity 1 within the UE.

[0451] 3) The access network determines the second indication information corresponding to the target information interaction. For example, the second indication information corresponding to the measurement report related information interaction of the access network allocation data 1 is 01.

[0452] 4) The access network determines the correspondence between the first indication information and the target logical function entity. For example, the access network determines that 001 corresponds to logical function entity 1. The access network also determines the correspondence between the first indication information and the second indication information. For example, the access network determines that 001 corresponds to 01. This can also be understood as the access network determining the correspondence between the first indication information and <target logical function entity, second indication information>. For example, the access network determines that 001 corresponds to <logical function entity 1, 01>.

[0454] 9) The access network determines the target logical function entity corresponding to the first indication information based on the correspondence between the first indication information and the target logical function entity, and forwards the second information corresponding to the first indication information to the target logical function entity. For example, the access network determines that 001 corresponds to logical function entity 1 and forwards the second information corresponding to 001 to logical function entity 1. The access network also determines the second indication information corresponding to the first indication information based on the correspondence between the first indication information and the second indication information, and indicates to the target logical function entity that the second information corresponds to the second indication information. For example, the access network determines that 001 corresponds to the second indication information 01 and indicates to logical function entity 1 that the first information corresponds to 01.

[0455] It can also be understood that the access network determines the <target logical function entity, second indication information> corresponding to the first indication information based on the correspondence between the first indication information and the <target logical function entity, second indication information>, forwards the second information to the target logical function entity, and indicates that the second information corresponds to the second indication information. For example, the access network determines that 001 corresponds to <logical function entity 1, 01>, forwards the first information to logical function entity 1, and indicates that the first information corresponds to 01.

[0456] 10) The target logical function entity determines that the target information interaction corresponding to the first information corresponds to the second indication information. For example, the logical function entity 1 determines that the measurement report related information interaction of the data 1 corresponding to the first information corresponds to 01.

[0457] 11) The target logical function entity generates new third information for target information exchange and sends the new third information to the access network. For example, logical function entity 1 needs to exchange measurement report-related information for data 1 with the UE. Logical function entity 1 generates new third information for measurement report-related information exchange for data 1 and sends it to the access network. The target logical function entity determines the second indication information corresponding to the new third information based on the second indication information corresponding to the target information exchange, and indicates to the access network that the new third information corresponds to the second indication information. For example, logical function entity 1 determines that the new third information for measurement report-related information exchange for data 1 corresponds to 01 based on the measurement report-related information exchange for data 1, and indicates to the access network that the new third information corresponds to 01.

[0458] 12) The access network determines the first indication information corresponding to <target logical function entity, second indication information>, and forwards new third information to the UE, indicating that the new third information corresponds to the first indication information. For example, the access network determines 001 corresponding to <logical function entity 1, 01>, and forwards new third information to the UE, indicating that the new third information corresponds to 001.

Logical function entity 2 indicates to the access network that measurement report-related information for data 2 needs to be exchanged with the UE. The access network determines that the target logical function entity is logical function entity 2. Logical function entity 2 sends third information regarding measurement report-related information for data 2 to the access network. The access network assigns first indication information corresponding to the exchange of measurement report-related information for data 2 as 002. The access network assigns second indication information corresponding to the exchange of measurement report-related information for data 2 as 01. The access network determines that the first indication information 002 corresponds to logical function entity 2. The access network also determines that the first indication information 002 corresponds to the second indication information 01. The access network indicates to the UE that the exchange of measurement report-related information for data 2 corresponds to the first indication information 002. The access network sends third information regarding the exchange of measurement report-related information for data 2 to the UE.

The UE determines that the target logical function entity within the UE corresponding to the first indication information 004 is, for example, the processing entity 2, and delivers the new third information to the processing entity 2 within the UE.

[0463] In the embodiment of the present disclosure, when the second indication information and the first indication information are the same indication information, the access network is not required to determine the second indication information corresponding to the target information interaction (step 3), the access network is not required to further determine the correspondence between the first indication information and the second indication information (step 4), the access network is not required to further determine the second indication information corresponding to the first indication information based on the correspondence between the first indication information and the second indication information (step 9), and the access network is not required to determine the first indication information corresponding to <target logical function entity, second indication information> (step 12).

[0471] 2) The access network determines first indication information corresponding to the target information interaction; optionally, the access network determines second indication information corresponding to the target information interaction.

[0472] 3) The access network determines the correspondence between the first indication information and the target logical function entity; optionally, the access network determines the correspondence between the first indication information and the second indication information.

[0473] 4) The access network indicates to the UE the first indication information corresponding to the target information interaction;

[0474] 5) The fifth logical function entity indicates to the sixth logical function entity the correspondence between the first indication information and the target logical function entity. The fifth logical function entity may also indicate to the sixth logical function entity the address or identifier of the target logical function entity. Optionally, the fifth logical function entity indicates to the sixth logical function entity the correspondence between the first indication information and the second indication information.

[0475] The following is performed by the sixth logical function entity:

[0477] 7) The access network determines the target logical function entity corresponding to the first indication information according to the correspondence between the first indication information and the target logical function entity, and forwards the second information to the target logical function entity.

[0478] Among them, 4) can also be executed by the sixth logical function entity.

[0484] Similarly, the connection in Figure 20 is a logical connection and does not limit the connection between the two entities to a direct connection. The number of first logical functional entities in Figure 20 is for example only. The embodiments of the present disclosure do not limit the number of first logical functional entities, and the number of first logical functional entities can be one or more.

[0485] Optionally, FIG. 19 or FIG. 20 may be combined with the above-mentioned embodiments 1 / 2 / 3 / 4 / 5, or may be combined with the embodiments described in FIG. 3 to FIG. 17 .

[0486] In summary, by allocating / configuring the indication information (first indication information) for the interaction of different business / function / service related information, it is avoided to define a special information element or RRC message carrying information for each information interaction in the standard protocol, and the protocol design is flexible.

[0487] Specifically, a business / function / service-related information exchange between the UE and the network function is assigned a first indication message. The access network matches the first indication message with the network function corresponding to the business / function / service so that the business / function / service-related information can be forwarded to the corresponding network function. The UE matches the first indication message with the business / function / service-related information exchange so as to identify and process the business / function / service-related information. Since the first indication message can correspond to different network function instances of the same network function, the problem of the UE simultaneously exchanging information with multiple network functions of the same type can be solved.

[0488] Each interaction of service / function / service-related information between the UE and the network function is assigned a first indication message. The access network associates the first indication message with the network function corresponding to the service / function / service so that the service / function / service-related information can be forwarded to the corresponding network function.
