Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an information transmission method, apparatus, and storage medium. Background Art

[0002] 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 a UE (User Equipment) and a RAN (Radio Access Network), so that the RAN can identify the corresponding control plane information based on the RRC information elements and RRC messages.

[0003] However, in future 6G (6th Generation Mobile Communication Technology), the RAN may be reconstructed into multiple wireless network functions. For example, wireless access functions, positioning functions, sensing functions, AI (Artificial Intelligence) functions, etc. All the information exchanged between each separated wireless network function and the UE needs to be transmitted through the RAN. If the existing technology is still used to define dedicated RRC information elements or RRC messages for each type of information in the standard protocol to carry the messages, the workload is large, the protocol is cumbersome and redundant, the readability is poor, and there may be coupling between different functional protocols.

[0101] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0102] In the embodiments of the present application, the term "plurality" refers to two or more, and other quantifiers are similar.

[0103] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0104] In the related art, the signaling exchanged between the UE and the network in 5G includes the RRC messages between the UE and the RAN, and the NAS (Non-Access Stratum) messages between the UE and the CN (Core Network). Among them, the transmission of the NAS messages over the air interface is carried on top of the RRC, and multiple messages that can carry NAS information are defined in the RRC messages. In the base station architecture where the gNB-CU (Centralized Unit) and the gNB-DU (Distributed Unit) are separated, the end point of the RRC protocol in the base station is the gNB-CU. In the base station architecture where the gNB-CU-CP (Control Plane) and the gNB-CU-UP (User Plane) are separated, the end point of the RRC protocol in the base station is the gNB-CU-CP.

[0105] Figure 1 is a schematic diagram of the control plane protocol stack in the related art. As Figure 1As shown in the figure, 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 executed by the RLC layer and the MAC layer in the control plane are the same as those in the user plane. The RRC layer protocol terminates at the gNB and mainly provides functions such as broadcasting, paging, RRC connection management, RB (Radio Bearer) control, mobility management, UE measurement reporting and control. The NAS layer terminates at the AMF (Access and Mobility Management Function) and mainly implements functions such as mobility management, paging, and security control of the 5GS (5G System).

[0106] Among them, there is a NAS-MM (Mobility Management) protocol between the UE and the AMF in the CN. There are multiple protocols between the terminal and the core network functions (excluding the AMF) that need to be transmitted through the NAS-MM protocol. These protocols include: session management signaling, short messages, UE policies, and LCS (Location Service). The NAS messages of these protocols are forwarded by the AMF between the UE and the corresponding core network functions. Optionally, the NAS transmissions of SM (Session Management), SMS (Short Messaging Service), UE Policy, and LCS can be as Figure 2 shown in the figure.

[0107] In addition, a set of NFs (Network Functions) are included in the 5G system architecture. An NF is a processing function in the system, which defines the functional behavior and interfaces. An 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 cloud infrastructure. The 5G system architecture is defined as a service-based architecture, that is, a system architecture that realizes system functions by a set of NFs providing services to other authorized NFs to access their services. An NF service is a function exposed by an NF (as an NF service producer) to other authorized NFs (as NF service consumers) through service-based interfaces. An NF service can support one or more NF service operations. An NF can provide different NF services.

[0108] In summary, for the control plane information transmitted between the UE and the RAN in 5G, the RAN can only recognize two types. One is the information generated by the RRC protocol layer itself, and the other is NAS information. The endpoints of the interaction of the two types of information 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 respectively, and distinguish these two types of information according to the RRC information elements and RRC messages.

[0109] However, in future 6G, the RAN may be reconstructed into multiple radio network functions. For example, radio access functions, positioning functions, sensing functions, AI functions, etc. The separated radio network functions can evolve independently, be developed independently, and be deployed independently. And in future 6G, the NFs of the CN may interact directly with the RAN without being forwarded by the AMF. For example, the SMF (Session Management Function) and the LMF (Location Management Function) can interact directly with the RAN. That is, in future 6G, there are more types of NFs (NFs in the RAN and NFs in the CN) interacting with the UE by signaling, and the information exchanged between various NFs and the UE needs to be transmitted through the RAN. If the existing technology is still used to define dedicated RRC information elements or RRC messages for each type of information in the standard protocol to carry the messages, the workload is large, the protocol is cumbersome and redundant, the readability is poor, and there may be coupling between different functional protocols. In addition, the existing technology does not design for the situation where the UE interacts with multiple network functions of the same service / function type simultaneously.

[0110] Therefore, to solve the above problems, the present application proposes an information transmission method, apparatus, and storage medium to support the interaction of multiple NFs with the UE, and when the UE interacts with multiple NFs of the same type simultaneously, the RAN can forward the interaction information to the corresponding NF, the NF can identify the service corresponding to the interaction information, and the UE can deliver the interaction information to the corresponding processing entity within the UE.

[0111] Among them, the method and the apparatus are based on the same inventive concept. Since the principles of the method and the apparatus for solving problems are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be described again.

[0112] The technical solutions provided by the embodiments of the present application can be applied to a variety of systems, especially future communication systems, such as 6G systems. For example, the applicable systems can 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. Both terminal devices and network devices are included in these various systems. The system may also include a core network part, such as EPS (Evolved Packet System), 5GC (5G Core Network), etc.

[0113] The terminal device involved in the embodiments of the present application can be a device that provides voice and / or data connectivity to users, such as a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called a UE. The wireless terminal device can communicate with one or more CNs via the RAN. The wireless terminal device can be a mobile terminal device, such as a mobile phone (or called a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges language and / or data with the radio access network. For example, devices such as PCS (Personal Communication Service) phones, cordless phones, SIP (Session Initiated Protocol) phones, WLL (Wireless Local Loop) stations, PDAs (Personal Digital Assistant), etc. The wireless terminal device can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, a user device, which is not limited in the embodiments of the present application.

[0114] The network device involved in the embodiments of the present application can be a base station, which may include multiple cells that provide services to terminals. Depending on specific application scenarios, the base station can also be referred to as an access point, or it can be a device in the access network that communicates with wireless terminal devices through one or more sectors over the air interface, or other names. The network device can be used to mutually replace the received air frames and IP (Internet Protocol) packets, acting as a router between the wireless terminal device and the rest of the access network; where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application can be a BTS (Base Transceiver Station) in GSM or CDMA, or a NodeB (network device) in WCDMA, or an eNB or e-NodeB (evolutional Node B) in the LTE system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a HeNB (Home evolved Node B), a relay node, a femto, a pico, etc. The embodiments of the present application do not limit this. In some network architectures, the network device can include a CU (Centralized Unit) node and a DU (Distributed Unit) node, and the CU and DU can also be geographically separated.

As an example, the access network device can be any logical functional entity in the RAN, such as a network function, a logical node, a logical unit, etc.

[0119] Optionally, the logical function 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. This application places no restrictions on this.

[0120] As Figure 3 shown, the information transmission method may include the following steps:

[0121] Step 301, receive first information sent by a first terminal device or a first logical function entity.

[0122] The first information is used to indicate initiating a target information interaction, where the target information interaction includes information interaction of a target service 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.

[0123] The first logical function entity is a logical function entity in the network or a second terminal device, and the logical function entity in the network is a logical function entity in the access network or a logical function entity in the core network.

[0124] 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 information interaction between the first terminal device and the second terminal device.

[0125] Optionally, when the first logical function entity is the second terminal device, the first terminal device can perform a target information interaction with a logical function entity in the second terminal device. At this time, the logical function entity that performs the target information interaction with the first terminal device is the logical function entity in the terminal device other than the first terminal device.

[0126] Similarly, the first logical function 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. This embodiment places no restrictions on this.

[0127] For example, the first logical function entity includes one or more of the following: a logical function entity in the access network, a logical function entity in the core network. Or, the first logical function entity includes one or more of the following: a logical function entity of the control plane, a logical function entity of the user plane.

[0128] 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, sensing function, location / location 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, and so on. The UE data includes one or more of the following: data between the UE and the data network, data between the UE and the logical function entity in the network, and data between the UE and another UE.

[0129] Among them, the target service or target function or target service includes at least one of the following: UE data transmission, session management, short message, UE policy, location or location, sensing, AI, services or functions or services of the core network.

[0130] It should be noted that different services / functions / services may belong to the same type of service / function / service. For example, the UE data transmission of slice 1 and the UE data transmission of slice 2 both belong to the service / function / service of the UE data transmission type. For another example, the session management of slice 1 and the session management of slice 2 both belong to the service / function / service of the session management type. For another example, the session management of session 1 and the session management of session 2 both belong to the service or function or service of the session management type. For another example, the sensing with provided capability / service quality 1 and the sensing with provided capability / service quality 2 both belong to the service / function / service of the sensing type. For another example, the sensing of service 1 and the sensing of service 2 both belong to the service / function / service of the sensing type. And so on.

[0131] It should be noted that in this application, the first terminal device can simultaneously perform information interactions for multiple services / functions / services respectively. Optionally, the first terminal device can simultaneously perform information interactions for multiple types of services / functions / services, or the first terminal device can simultaneously perform information interactions for multiple services / functions / services of the same type of service / function / service. For example, the first terminal device can simultaneously perform information interactions for session management and UE policy respectively. For another example, the first terminal device can simultaneously perform information interactions for the session management of slice 1 and the session management of slice 2 respectively. For another example, the first terminal device can simultaneously perform information interactions for the sensing of service 1 and the sensing of service 2 respectively. And so on.

[0132] It should be noted that in this application, there is a corresponding relationship between the target information interaction and the first logical function entity. Optionally, one target information interaction and one first logical function entity can be in one-to-one correspondence, that is, the first terminal device performs information interaction of one target service or target function or target service with one first logical function entity. For example, the information interaction of session management for slice 1 corresponds to SMF1. The information interaction of session management for slice 2 corresponds to SMF2. Optionally, it is also possible that multiple target information interactions correspond to one first logical function entity, that is, the first terminal device performs information interaction of multiple target services or target functions or target services with one first logical function entity. As an example, in the case where one first logical function entity includes multiple target services or target functions or target services, the first terminal device can perform information interaction of multiple target services or target functions or target services with this first logical function entity. For example, the information interaction of session management for session 1 and the information interaction of session management for session 2 correspond to the same SMF. Another example is that the information interaction of perception for service 1 and the information interaction of perception for service 2 correspond to the same perception function.

[0133] In some embodiments, the access network device may receive a first piece of information sent by the first terminal device or the first logical function entity for instructing to initiate a target information interaction (information interaction between the first terminal device and the first logical function entity), so as to inform the access network device that the first terminal device or the first logical function entity is going to initiate a target information interaction.

[0134] It should be noted that in this application, if the first terminal device indicates that information interaction of a target service or target function or target service (target information interaction) is required, that is, the access network device receives the first piece of information sent by the first terminal device. At this time, since the first terminal device does not indicate the first logical function entity for performing the target information interaction with the first terminal device, the access network device can determine the first logical function entity corresponding to the target information interaction.

[0135] As a possible implementation manner, the access network device may determine the first logical function entity for performing the target information interaction with the first terminal device according to the target service or target function or target service, where the first logical function entity supports the target service or target function or target service. Or, it may determine the first logical function entity for performing the target information interaction with the first terminal device according to the target logical function entity type of the target information interaction, where the first logical function entity belongs to the target logical function entity type. Or, it may receive the first logical function entity determined by the second logical function entity for performing the target information interaction with the first terminal device.

[0136] Optionally, the access network device may indicate a target service or a target function or a target service to a logical function entity (the second logical function entity), and the logical function entity may indicate to the access network device a first logical function entity for performing target information interaction with the first terminal device. For example, for a target service or a target function or a target service included in the core network function, the access network device may indicate the target service or the target function or the target service to a logical function entity in the core network (for example, the AMF or the NRF), so that a logical function entity in the core network indicates to the access network device a first logical function entity for performing target information interaction with the first terminal device.

[0137] In the case where the access network device indicates a target service or a target function or a target service, the access network device may indicate one or more of the following: the service / function / service / logical function entity type of the target service or the target function or the target service, and the relevant parameter information of the target service or the target function or the target service. In the case where the access network device indicates the service / function / service type of the target service or the target function or the target service, the first logical function entity includes the service / function / service of the service / function / service type. In the case where the access network device indicates the logical function entity type of the target service or the target function or the target service, the first logical function entity belongs to the logical function entity type.

[0138] It should be noted that in the case where the first terminal device indicates that information interaction for a target service or a target function or a target service (target information interaction) needs to be performed, the first terminal device may indicate one or more of the following: the service / function / service / logical function entity type of the target service or the target function or the target service, and the relevant parameter information of the target service or the target function or the target service. In the case where the first terminal device indicates the service / function / service type of the target service or the target function or the target service, the first logical function entity includes the service / function / service of the service / function / service type. In the case where the first terminal device indicates the logical function entity type of the target service or the target function or the target service, the first logical function entity belongs to the logical function entity type.

[0139] It should be noted that in this application, if the first logical function entity indicates that information interaction for a target service or a target function or a target service (target information interaction) needs to be performed, that is, the access network device receives the first information sent by the first logical function entity, the first logical function entity may indicate to the access network device that the first terminal device is for performing target information interaction with the first logical function entity. Therefore, the access network device may determine that the target information interaction is the information interaction between the first terminal device and the first logical function entity.

[0140] When the first terminal device indicates the need for information interaction (target information interaction) of a target service, target function, or target service, optionally, the first terminal device may also send relevant service information of the information interaction of the target service, target function, or target service to the access network device. The first terminal device may indicate to the access network device to initiate target information interaction and send relevant service information to the access network device in one message or different messages.

[0141] Similarly, when the first logical function entity indicates the need for information interaction (target information interaction) of a target service, target function, or target service, optionally, the first logical function entity may also 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 indicate to the access network device to initiate target information interaction and send relevant service information to the access network device in one message or different messages.

[0142] Step 302, indicate the 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.

[0143] 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.

[0144] It can also be understood that the first indication information is used to indicate the relevant service information of the target information interaction between the first terminal device and the access network device.

[0145] In some embodiments, the access network device may indicate the 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 independently by the access network device, may be determined independently by the first terminal device, or may be jointly determined by the access network device and the first terminal device, and this application does not limit this.

[0146] Optionally, the first indication information may be one of the following: number, identifier, index, radio bearer, logical channel, transport channel, physical channel.

[0147] It should be noted that in this application, there is a corresponding relationship between the target information interaction and the first indication information. Optionally, one target information interaction and one first indication information can be in one-to-one correspondence. For example, the first indication information 1 corresponds to the target information interaction 1. The first indication information 2 corresponds to the target information interaction 2. Optionally, it is also possible that multiple target information interactions correspond to one first indication information. For example, the target information interaction 1 and the target information interaction 2 can both correspond to the first indication information 1.

[0148] Suppose the target information interaction 1 (the information interaction between the first terminal device and the first logical function entity 1) has already corresponded to the first indication information 1. If the target information interaction 2 is the information interaction between the first logical function entity 1 and the first terminal device or other terminal devices or other logical function entities, then since the first logical function entity 1 has already corresponded to the first indication information 1, the target information interaction 2 can either correspond to a different first indication information 2 from the first indication information 1 or correspond to the first indication information 1. This application does not limit this. It can also be understood that the access network determines the first indication information corresponding to the target information interaction according to 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.

[0149] As a possible implementation manner, 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. Or, receive the first indication information corresponding to the target information interaction indicated by the first terminal device (in this case, the first indication information is determined separately by the first terminal device).

[0150] As another possible implementation manner, the first indication information includes a first type indication information and a first instance indication information, so that the access network device can perform at least one of the following:

[0151] Determine the first type indication information in the first indication information corresponding to the target information interaction and indicate the first type indication information corresponding to the target information interaction to the first terminal device; or,

[0152] Determine the 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,

[0153] Determine the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction and indicate the first type indication information and the first instance indication information corresponding to the target information interaction to the first terminal device; or,

[0154] Receive the first type of indication information in the first indication information corresponding to the target information interaction indicated by the first terminal device; or,

[0155] Receive the first instance indication information in the first indication information corresponding to the target information interaction indicated by the first terminal device; or,

[0156] Receive the first type of 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.

[0157] 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 function entity. And, the first indication information may be per UE.

[0158] In summary, the first indication information may have the following two ways:

[0159] Way 1: The first indication information includes an indication information.

[0160] The first indication information 1 corresponds to the information interaction of service / function / service / logical function entity 1, and the first indication information 2 corresponds to the information interaction of service / function / service / logical function entity 2. Service / function / service / logical function entity 1 and service / function / service / logical function entity 2 may be different types of service / function / service / logical function entities, or the same type of service / function / service / logical function entity, and this application does not limit this.

[0161] For example, the first indication information 1 corresponds to the information interaction of session management for slice 1. The first indication information 2 corresponds to the information interaction of session management for slice 2. The first indication information 3 corresponds to the information interaction of sensing for service 1. The first indication information 4 corresponds to the information interaction of sensing for service 2.

[0162] Another example, the first indication information 1 corresponds to the information interaction of logical function entity 1, and logical function entity 1 includes session management for slice 1. The first indication information 2 corresponds to the information interaction of logical function entity 2, and logical function entity 2 includes session management for slice 2. The first indication information 3 corresponds to the information interaction of logical function entity 3, and logical function entity 3 includes sensing for service 1. The first indication information 4 corresponds to the information interaction of logical function entity 4, and logical function entity 4 includes sensing for service 2.

[0163] Note: It is not excluded that multiple first indication information corresponds to one logical function entity.

[0164] Way 2: The first indication information includes the first type of indication information and the first instance indication information.

[0165] Among them, the first type of indication information indicates the type of a service / function / service / logical function entity. The first instance of indication information indicates one or more of the following: the information interaction of one or more services / functions / services in a service / function / service type, and the information interaction of a logical function entity in a logical function entity type.

[0166] The first type of indication information 1 corresponds to the information interaction of the service / function / service / logical function entity type 1, and the first type of indication information 2 corresponds to the information interaction of the service / function / service / logical function entity type 2. The first instance of indication information 1 corresponds to the information interaction of the service / function / service / logical function entity 1 of a given service / function / service / logical function entity type, and the first instance of indication information 2 corresponds to the information interaction of the service / function / service / logical function entity 2 of the same given service / function / service / logical function entity type.

[0167] 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 of indication information 1 and the first instance of indication information 1 (the first instance of indication information 1 under the first type of 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 of indication information 1 and the first instance of indication information 2 (the first instance of indication information 2 under the first type of 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 of indication information 2 and the first instance of indication information 1 (the first instance of indication information 1 under the first type of 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 of indication information 2 and the first instance of indication information 2 (the first instance of indication information 2 under the first type of indication information 2).

[0168] For another example, the first indication information 1 corresponds to the information interaction of the logical function entity 1, and the logical function entity 1 includes the session management of slice 1. 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 logical function entity 1, and the logical function entity 1 includes the session management of slice 2. 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 logical function entity 1, and the logical function entity 1 includes the perception of service 1. 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 logical function entity 1, and the logical function entity 1 includes the perception of service 2. 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).

[0169] Service / function / service type, for example, session management type, short message type, UE policy type, location / location type, perception type, AI type, core network service / function / service type.

[0170] Logical function entity type, for example, session management function type, short message function type, UE policy function type, location / location function type, perception function type, AI function type, core network logical function entity type.

[0171] The correspondence between the first type indication information and the service / function / service / logical function entity type it indicates can be defined in a standard protocol. The first type indication information can be one of the following: number, identifier, index, radio bearer, logical channel, transport channel, physical channel, message name / type, information element.

[0172] The first instance indication information can be one of the following: number, identifier, index, radio bearer, logical channel, transport channel, physical channel.

[0173] Note: It is not excluded that there are multiple first instance indication information corresponding to one logical function entity.

[0174] Optionally, for the above two ways of the first indication information, the access network device may have the following situations when determining the first indication information:

[0175] For Method 1, the access network device needs to allocate / configure the first indication information corresponding to the target information interaction. For Method 2, in one implementation, the access network device allocates / configures the first instance indication information in the first indication information corresponding to the target information interaction. The first type of indication information can be predefined or preconfigured. In another implementation, the access network device allocates / configures the first type of indication information and the second instance indication information in the first indication information corresponding to the target information interaction respectively.

[0176] Optionally, for the above two methods of the first indication information, when the access network device indicates the first indication information to the first terminal device, the following situations may exist:

[0177] For Method 1, the access network device indicates the first indication information corresponding to the target information interaction to the first terminal device. For Method 2, in one implementation, 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. In another implementation, the access network device indicates the first type of indication information and the first instance indication information in the first indication information corresponding to the target information interaction to the first terminal device. In yet another implementation, the access network device indicates the first type of indication information in the first indication information to the first terminal device. In still another implementation, the access network device indicates to the first terminal device to allocate / configure the first type of indication information and the first instance indication information in the first indication information corresponding to the target information interaction.

[0178] Similarly, for the above two methods of the first indication information, the following situations may exist when the first terminal device determines the first indication information:

[0179] For Method 1, the first terminal device needs to allocate / configure the first indication information corresponding to the target information interaction. For Method 2, in one implementation, 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 of indication information can be predefined or preconfigured. In another implementation, the first terminal device allocates / configures the first type of indication information and the second instance indication information in the first indication information corresponding to the target information interaction respectively.

[0180] Optionally, for the above two methods of the first indication information, the following situations may exist when the first terminal device indicates the first indication information to the access network device:

[0181] For Method 1, the first terminal device indicates the first indication information corresponding to the target information interaction to the access network device. For Method 2, in one implementation, 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. In another implementation, 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. In yet another implementation, the first terminal device indicates the first type indication information in the first indication information to the access network device. In still another implementation, the first terminal device indicates 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 to the access network device.

[0182] Optionally, according to the different entities for which the first indication information is allocated / configured, there can be the following different ways to determine the first indication information:

[0183] Method 1: The access network device allocates / configures the first indication information corresponding to the target information interaction

[0184] 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.

[0185] Method 2: The first terminal device allocates / configures the first indication information corresponding to the target information interaction

[0186] 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.

[0187] The first terminal device sends the first indication information corresponding to the target information interaction that is allocated / configured, 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.

[0188] Method 3: The access network device and the first terminal device allocate / configure the first indication information corresponding to the target information interaction

[0189] The access network device allocates / configures the first type indication information in the first indication information corresponding to the target information interaction. The first terminal device allocates / configures the first instance indication information in the first indication information corresponding to the target information interaction. The first terminal device sends the first instance indication information in the first indication information corresponding to the allocated / configured target information interaction to the access network device.

[0190] Alternatively, the access network device allocates / configures the instance indication information in the first indication information corresponding to the target information interaction. The first terminal device allocates / configures the first type indication information in the first indication information corresponding to the target information interaction. The first terminal device sends the first type indication information in the first indication information corresponding to the allocated / configured target information interaction to the access network device.

[0191] It should be noted that in this application, the access network device indicates the first indication information corresponding to the target information interaction to the first terminal device, which can be an explicit indication or an implicit indication. For an explicit indication, for example, the first terminal device indicates to the access network device the need for information interaction (target information interaction) of a target service or a target function or a target service, and the access network device indicates the first indication information corresponding to the target information interaction to the first terminal device. For an implicit indication, for example, 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. The third information belongs to the information interaction (target information interaction) of a target service or a target function or a target service, then the target information interaction corresponds to the first indication information.

[0192] The first terminal device indicates to the access network device to initiate the target information interaction and indicates the first indication information corresponding to the target information interaction to the access network device, which can be indicated to the access network device in one message or different messages. In the case of indicating to the access network device in one message, the message can also include the relevant service information of the target information interaction.

[0193] In the case where the first terminal device indicates the need for information interaction (target information interaction) of a target service or a target function or a target service and sends the relevant service information of the information interaction of the target service or the target function or the target service to the access network device, the access network device sends the relevant service information to the first logical function entity.

[0194] When a first logical function entity indicates the need for information interaction of a target service or a target function or a target service (target information interaction), and sends relevant service information of the information interaction of the target service or the target function or the target service to an access network device, the access network device sends the relevant service information to a first terminal device. The access network device sending the relevant service information to the first terminal device and indicating first indication information corresponding to the target information interaction to the first terminal device may be sent and indicated to the first terminal device in one message or different messages.

[0195] In this application, since a first indication information is assigned to the information interaction of a service / function / service between a UE and a network function, the access network device can associate the first indication information with the network function corresponding to the service / function / service, so as to be able to forward the relevant service information of the information interaction of the service / function / service to the corresponding network function. And the UE can also associate the first indication information with the information interaction of the service / function / service, so as to be able to identify and process the relevant service information of the information interaction of the service / function / service. In addition, since the first indication information can correspond to different network function instances of the same type of network function, the problem that the UE simultaneously interacts with multiple network functions of the same type can be solved.

[0196] For the information transmission method provided in this application, the access network device receives first information sent by a first terminal device or a first logical function entity, where the first information is used to indicate initiating target information interaction, so as to 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, where the first indication information is used to indicate 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 third information of the target information interaction sent by the first logical function entity to the first terminal device. Thus, by allocating indication information for different information interactions, it is avoided to define dedicated RRC information elements or RRC messages in the standard protocol to carry messages for each information interaction, and the protocol design is flexible. At the same time, different first indication information can be allocated to the information interactions of different network function instances of the same type of network function, so the problem that the UE simultaneously interacts with multiple network functions of the same type can be solved.

[0197] To clearly illustrate the previous embodiment, this embodiment provides another information transmission method. Figure 4 It is a schematic flowchart of the information transmission method according to the second embodiment of this application.

[0198] Similarly, the information transmission method of the embodiments of the present application is applied to an access network device. Optionally, the access network device may be any device in the RAN. As an example, the access network device may be any logical function entity in the RAN, for example, a network function, a logical node, a logical unit, etc.

[0199] Optionally, the logical function entity may be implemented as a network element on dedicated hardware, or as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform. This application does not limit this.

[0200] As Figure 4 shown, the information transmission method may include the following steps:

[0201] Step 401, receive the first information sent by the first terminal device or the first logical function entity.

[0202] Step 402, indicate the 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.

[0203] It should be noted that the execution processes of steps 401-402 may refer to the execution processes of steps 301-302 in the above embodiments. The principles are the same and will not be elaborated here.

[0204] Step 403, in the case of receiving the second information indicated by the first indication information sent by the first terminal device, send the second information to the first logical function entity corresponding to the target information interaction, and / or in the case of receiving the third information of the target information interaction 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.

[0205] It should be noted that in this application, the access network device includes a routing function for forwarding the service information related to the target information interaction to the corresponding first terminal device or the 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 the uplink interaction information, the first terminal device generates the service information related to the target information interaction (the second information), determines the first indication information corresponding to the target information interaction, and sends the second information indicated by the first indication information (indicating that the second information corresponds to the first indication information) to the access network device. 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 service information related to the target information interaction (the second information). For the downlink interaction information, the first logical function entity generates the service information related to the information interaction of the target service or the target function or the target service (the third information), 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 (indicating that the third information corresponds to the first indication information) to the first terminal device. The first terminal device receives the third information indicated by the first indication information and determines that the third information corresponds to the target information interaction according to the target information interaction corresponding to the first indication information. The first terminal device processes the service information related to the target information interaction (the third information). Optionally, the first terminal device may deliver the third information to the logical function entity for processing the target information interaction. The logical function entity in the first terminal device for processing the target information interaction processes the third information.

[0206] As a possible implementation manner, when receiving the second information indicated by the first indication information sent by the first terminal device, the access network device may, according to the corresponding relationship between the first indication information and the target information interaction, send the second information to the first logical function entity corresponding to the target information interaction, and / or, when receiving the third information of the target information interaction sent by the first logical function entity, the access network device may, according to the corresponding relationship between the first indication information and the target information interaction, send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction.

[0207] Specifically, when receiving the second information indicated by the first indication information sent by the first terminal device, the access network device may determine the target information interaction corresponding to the first indication information according to the corresponding relationship 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. When receiving the 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 according to the corresponding relationship 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.

[0208] Optionally, before the access network device sends the second information to the first logical function entity corresponding to the target information interaction, the access network device may also determine the first logical function entity corresponding to the target information interaction according to the corresponding relationship between the first indication information and the target information interaction and the corresponding relationship between the target information interaction and the first logical function entity.

[0209] It should be noted that in this application, after determining the first logical function entity corresponding to the target information interaction, when the first terminal device sends the relevant service information (second information) of the information interaction of the target service or target function or target service to the access network device, the access network device may forward the second information to the first logical function entity.

[0210] It should be noted that in this application, if the first logical function entity indicates that information interaction of the target service or 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 function entity, the first logical function entity may indicate to the access network device that the first terminal device is the one for target information interaction with the first logical function entity. Therefore, when receiving the third information of the target information interaction sent by the first logical function 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 function entity may indicate that the target information interaction is with the first terminal device when sending the third information of the target information interaction to the access network device.

[0211] In summary, when the first terminal device indicates that information interaction of the target service or target function or target service (target information interaction) is required and also sends the relevant service information (second information) of the information interaction of the target service or target function or target service to the access network device, after determining the first logical function entity corresponding to the target information interaction, the access network device may forward the second information to the first logical function entity.

[0212] When a first logical function entity indicates the need for information interaction for a target service, or a target function, or a target service (target information interaction), and also sends relevant service information (third information) of the information interaction of the target service, or the target function, or the target service to an access network device, the access network device, after determining first indication information corresponding to the target information interaction, may send the third information indicated by the first indication information to a first terminal device corresponding to the target information interaction (when the first logical function entity indicates to the access network device the need for target information interaction, it will indicate to the access network device that the first terminal device that performs the target information interaction with the first logical function entity).

[0213] For the information transmission method provided in this application, when the access network device receives second information indicated by the first indication information sent by the first terminal device, the access network device may send the second information to a first logical function entity corresponding to the target information interaction, and / or when the access network device receives third information of the 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. Thus, based on the first indication information, the access network device can forward relevant service information of the target information interaction to the corresponding first terminal device or the first logical function entity.

[0214] In this application, the access network device may further determine the correspondence between the first indication information and the first logical function entity. The following combines Figure 5 to illustrate this process.

[0215] Figure 5 is a schematic flowchart of the information transmission method according to the third embodiment of this application.

[0216] Similarly, the information transmission method of the embodiments of this application is applied to an access network device. Optionally, the access network device may be any device in the RAN. As an example, the access network device may be any logical function entity in the RAN, for example, a network function, a logical node, a logical unit, etc.

[0217] Optionally, the logical function entity may be implemented as a network element on dedicated hardware, or as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform. This application does not limit this.

[0218] As Figure 5 shown, the information transmission method may include the following steps:

[0219] Step 501, receive first information sent by the first terminal device or the first logical function entity.

[0220] Step 502: Indicate the 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.

[0221] It should be noted that the execution processes of steps 501 - 502 can refer to the execution processes of steps 301 - 302 in the above embodiments. The principles are the same and will not be elaborated here.

[0222] Step 503: Determine the correspondence between the first indication information and the first logical function entity.

[0223] In some embodiments, the access network device can associate the first indication information corresponding to the target information interaction with the first logical function entity corresponding to the target information interaction. Optionally, it can be directly associated or indirectly associated. This application does not limit this. Indirect association, for example, the first indication information corresponds to the target information interaction, and the target information interaction corresponds to the first logical function entity. Correspondingly, 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 function entity.

[0224] Optionally, the access network device can store / apply the correspondence between the first indication information and the first logical function entity. Or, the access network device can 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 function entity.

[0225] Optionally, one first logical function entity and one first indication information can be in one-to-one correspondence. For example, the first logical function entity 1 corresponds to the first indication information 1. The first logical function entity 2 corresponds to the first indication information 2. Optionally, it is also possible that one first logical function entity corresponds to multiple first indication information. For example, in the case where the information interactions of multiple services / functions / services correspond to one first logical function entity, and the information interaction of one service / function / service corresponds to one first indication information, one first logical function entity corresponds to multiple first indication information. For example, the first logical function entity 1 corresponds to the first indication information 1 and the first indication information 2.

[0226] Step 504: When receiving the second information indicated by the first indication information sent by the first terminal device, send the second information 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 receiving the third information of the target information interaction 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 according to the correspondence between the first indication information and the first logical function entity.

[0227] For uplink interaction information, a first terminal device generates relevant service information (second information) for target information interaction. The first terminal device determines first indication information corresponding to the target information interaction, and sends the second information indicated by the first indication information (indicating that the second information corresponds to the first indication information) to an access network device. After receiving the second information indicated by the first indication information, the access network device determines a first logical function entity corresponding to the first indication information according to the corresponding relationship 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) of the target information interaction. For downlink interaction information, the first logical function entity generates relevant service information (third information) for information interaction of a target service or a target function or a 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 according to the corresponding relationship between the first indication information and the first logical function entity, and sends the third information indicated by the first indication information (indicating that the third information corresponds to the first indication information) to the first terminal device. After receiving the third information indicated by the first indication information, the first terminal device determines that the third information corresponds to the target information interaction according to the target information interaction corresponding to the first indication information. 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 function entity for processing the target information interaction. The logical function entity in the first terminal device for processing the target information interaction processes the third information.

[0228] Among them, the access network device determining the first logical function entity corresponding to the first indication information according to the corresponding relationship between the first indication information and the first logical function entity may be directly determined or indirectly determined. For indirect determination, for example, the access network device determines the target information interaction corresponding to the first indication information according to the corresponding relationship between the first indication information and the target information interaction, and then determines the first logical function entity corresponding to the target information interaction according to the corresponding relationship between the target information interaction and the first logical function entity. The access network device determining the first indication information corresponding to the first logical function entity according to the corresponding relationship between the first indication information and the first logical function entity may be directly determined or indirectly determined. For indirect determination, for example, the access network device determines the target information interaction corresponding to the first logical function entity according to the corresponding relationship between the first logical function entity and the target information interaction, and then determines the first indication information corresponding to the target information interaction according to the corresponding relationship between the target information interaction and the first indication information.

[0229] In the information transmission method provided by this application, the access network device determines the correspondence between the first indication information and the first logical function entity, so that when receiving the second information indicated by the first indication information sent by the first terminal device, the access network device sends the second information 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 receiving the third information of the target information interaction sent by 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 according to the correspondence between the first indication information and the first logical function entity. Thus, based on the correspondence between the first indication information and the first logical function entity, the access network device can forward the relevant service information of the target information interaction to the corresponding first terminal device or the first logical function entity.

[0230] In this application, a second indication information can also be allocated for the target information interaction. The following will describe this process in conjunction with Figure 6 this.

[0231] Figure 6 is a schematic flowchart of the information transmission method provided by the fourth embodiment of this application.

[0232] Similarly, the information transmission method of the embodiments of this application is applied to the 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 function entity in the RAN, such as a network function, a logical node, a logical unit, etc.

[0233] Optionally, the logical function entity can be implemented as a network element on dedicated hardware, or as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform. This application does not limit this.

[0234] As Figure 6 shown, the information transmission method may include the following steps:

[0235] Step 601, receive the first information sent by the first terminal device or the first logical function entity.

[0236] Step 602, indicate the 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.

[0237] It should be noted that the execution processes of steps 601-602 can refer to the execution processes of steps 301-302 in the above embodiments. The principles are the same and will not be elaborated here.

[0238] Step 603: Send the 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.

[0239] 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.

[0240] It can also be understood that the second indication information is used to indicate the relevant service information of the target information interaction between the first logical function entity and the access network device.

[0241] In some embodiments, the access network device may send the 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 independently by the access network device, or may be determined independently by the first logical function entity, or may be jointly determined by the access network device and the first logical function entity. This application does not limit this.

[0242] Optionally, the second indication information may be one of the following: number, identifier, index, radio bearer, logical channel, transport channel, physical channel.

[0243] It should be noted that in this application, there is also a corresponding relationship between the target information interaction and the second indication information. Optionally, one target information interaction and one second indication information may be in one-to-one correspondence. For example, the second indication information 1 corresponds to the target information interaction 1. The second indication information 2 corresponds to the target information interaction 2. Optionally, it is also possible that multiple target information interactions correspond to one second indication information. For example, the target information interaction 1 and the target information interaction 2 may both correspond to the second indication information 1.

[0244] It should be noted that in this application, the access network device sending the second indication information corresponding to the target information interaction to the first logical function entity may be an explicit indication or an implicit indication. For an explicit indication, for example, the first logical function entity indicates to the access network device the need for information interaction of a target service or a target function or a target service (target information interaction), and the access network device indicates the second indication information corresponding to the target information interaction to the first logical function entity. For an implicit indication, 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 of a target service or a target function or a target service (target information interaction), then the target information interaction corresponds to the second indication information.

[0245] In this application, since a second indication information is assigned to the information interaction of a service / function / service between the UE and the network function, the network function can associate the second indication information with the relevant service information of the information interaction of the service / function / service, so as to be able to identify and process the relevant service information of the information interaction of the service / function / service. In addition, since the second indication information can correspond to the information interactions of different services / functions / services of the same network function, the problem of the UE simultaneously performing information interactions of multiple services / functions / services with the same network function can be solved.

[0246] As a possible implementation manner, the second indication information includes an 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, receive 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 separately by the first logical function entity).

[0247] As another possible implementation manner, the second indication information includes a second type indication information and a second instance indication information, so that the access network device can perform at least one of the following:

[0248] Determine the second type indication information in the second indication information corresponding to the target information interaction and indicate the second type indication information corresponding to the target information interaction to the first logical function entity; or,

[0249] Determine the 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,

[0250] Determine the second type indication information and the second instance indication information in the second indication information corresponding to the target information interaction and indicate the second type indication information and the second instance indication information corresponding to the target information interaction to the first logical function entity; or,

[0251] Receive the second type indication information in the second indication information corresponding to the target information interaction indicated by the first logical function entity; or,

[0252] Receive the second instance indication information in the second indication information corresponding to the target information interaction indicated by the first logical function entity; or,

[0253] Receive the second type indication information and the second instance indication information in the second indication information corresponding to the target information interaction indicated by the first logical function entity.

[0254] Optionally, the second indication information may correspond to one or more of the following: information interaction of services / functions / services, information interaction of logical function entities within the UE. Also, the second indication information may be per UE, or per the first logical function entity, or both per UE and per the first logical function entity, and this application does not limit this.

[0255] It should be noted that in this application, the second indication information and the first indication information may be the same or different. When the second indication information is the same as the first indication information, the access network device determining the first indication information is also determining the second indication information.

[0256] The first logical function entity indicating to the access network device to initiate the target information interaction, and indicating to the access network device the second indication information corresponding to the target information interaction, may be indicated to the access network device in one message or different messages. When indicating to the access network device in one message, the message may further include relevant service information of the target information interaction.

[0257] Step 604, when receiving the second information indicated by the first indication information sent by the first terminal device, send the second information to the first logical function entity corresponding to the target information interaction, and / or, when receiving the third information of the target information interaction 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.

[0258] It should be noted that the execution process of this step may refer to the execution process of step 403 in the above embodiment, with the same principle and will not be elaborated here. The execution process of this step may also refer to the execution process of step 504 in the above embodiment. Before this step, the access network device may also execute step 503, with the same principle and will not be elaborated here.

[0259] As a possible implementation, when receiving the second information indicated by the first indication information sent by the 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 the 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.

[0260] For uplink interaction information, a first terminal device generates relevant service information (second information) for target information interaction. The first terminal device determines first indication information corresponding to the target information interaction and sends the second information indicated by the first indication information (indicating that the second information corresponds to the first indication information) to an access network device. After receiving the second information indicated by the first indication information, the access network device sends the second information indicated by a second indication information to a first logical function entity corresponding to the target information interaction. After receiving the second information indicated by the second indication information, the first logical function entity determines the target information interaction corresponding to the second information according to the target information interaction corresponding to the second indication information. The first logical function entity processes the relevant service information (second information) of the target information interaction. For downlink interaction information, the first logical function entity generates relevant service information (third information) for information interaction of a target service or a target function or a target service. The first logical function entity determines second indication information corresponding to the target information interaction and sends the third information indicated by the second indication information (indicating that the third information corresponds to the second indication information) to the access network device. 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 (indicating that the third information corresponds to the first indication information) to the first terminal device. After receiving the third information indicated by the first indication information, the first terminal device determines the target information interaction corresponding to the third information according to the target information interaction corresponding to the first indication information. 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 function entity for processing the target information interaction. The logical function entity in the first terminal device for processing the target information interaction processes the third information.

[0261] As a possible implementation manner, when receiving the second information indicated by the first indication information sent by the first terminal device, the access network device may, according to the corresponding relationship between the first indication information and the target information interaction and the corresponding relationship between the second indication information and the target information interaction, 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 the third information indicated by the second indication information sent by the first logical function entity, the access network device may, according to the corresponding relationship between the first indication information and the target information interaction and the corresponding relationship between the second indication information and the target information interaction, send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction.

[0262] Specifically, when the access network device receives the second information indicated by the first indication information sent by the first terminal device, the access network device may determine the target information interaction corresponding to the first indication information according to the corresponding relationship between the first indication information and the target information interaction, determine the second indication information corresponding to the target information interaction according to the corresponding relationship 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. When the access network device receives the third information indicated by the second indication information sent by the first logical function entity, the access network device may determine the target information interaction corresponding to the second indication information according to the corresponding relationship between the target information interaction and the second indication information, determine the first indication information corresponding to the target information interaction according to the corresponding relationship 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.

[0263] It can also be understood that when the access network device receives the second information indicated by the first indication information sent by the first terminal device, the access network device may determine the target information interaction corresponding to the first indication information according to the corresponding relationship 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 according to the corresponding relationship between the target information interaction and the <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. When the access network device receives the third information indicated by the second indication information sent by the first logical function entity, the access network device may determine the target information interaction corresponding to the <first logical function entity, second indication information> according to the corresponding relationship between the target information interaction and the <first logical function entity, second indication information>, determine the first indication information corresponding to the target information interaction according to the corresponding relationship 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.

[0264] It should be noted that the <X, Y> symbols throughout the text represent the combination of the two. For example, the above <first logical function entity, second indication information> represents the combination of the first logical function entity and the second indication information.

[0265] 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 may also determine the first logical function entity corresponding to the target information interaction according to the corresponding relationship between the first indication information and the target information interaction and the corresponding relationship between the target information interaction and the first logical function entity.

[0266] 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 may further determine the first logical function entity corresponding to the first indication information according to the correspondence between the first indication information and the first logical function entity.

[0267] In the information transmission method provided in this application, the access network device may send the 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. Thus, the network function can associate the second indication information with the relevant service information of the information interaction of the service / function / service, so as to be able to identify and process the relevant service information of the information interaction of the service / function / service. At the same time, different second indication information can be assigned to the information interactions of different services / functions / services of the same network function, so the problem that the UE simultaneously performs information interactions of multiple services / functions / services with the same network function can be solved.

[0268] It should be noted that in this application, the access network device may further 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. The following combines Figure 7 , to illustrate this process.

[0269] Figure 7 is a schematic flowchart of the information transmission method provided in the fifth embodiment of this application.

[0270] Similarly, the information transmission method of the embodiments of this application is applied to the access network device. Optionally, the access network device may be any device in the RAN. As an example, the access network device may be any logical function entity in the RAN, such as a network function, a logical node, a logical unit, etc.

[0271] Optionally, the logical function entity may be implemented as a network element on dedicated hardware, or as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, and this application does not limit this.

[0272] As Figure 7 shown, the information transmission method may include the following steps:

[0273] Step 701, receive the first information sent by the first terminal device or the first logical function entity.

[0274] Step 702, indicate the 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.

[0275] 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.

[0276] It should be noted that the execution processes of steps 701 - 703 can refer to the execution processes of steps 601 - 603 in the above embodiments. The principles are the same and will not be elaborated here.

[0277] Step 704, when the second indication information is different from the first indication information, determine the corresponding relationship between the second indication information and the first indication information.

[0278] In some embodiments, the access network device can determine the corresponding relationship 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 correlates 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 correlated or indirectly correlated, and this application does not limit this. Indirect correlation is, for example, the first indication information corresponds to the target information interaction, and the target information interaction corresponds to the second indication information. Correspondingly, the access network device determines the corresponding relationship between the first indication information and the target information interaction, and the corresponding relationship 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.

[0279] Optionally, the access network device can store / apply the corresponding relationship between the second indication information and the first indication information. Or, the access network device can store / apply the corresponding relationship between the first indication information and the target information interaction, and the corresponding relationship between the target information interaction and the second indication information.

[0280] Optionally, one second indication information and one first indication information can be in one-to-one correspondence. For example, second indication information 1 corresponds to first indication information 1. Second indication information 2 corresponds to first indication information 2. Optionally, it is also possible that one second indication information corresponds to multiple first indication information. For example, in the case where the information interactions of multiple services / functions / services correspond to one second indication information, and the information interaction of one service / function / service corresponds to one first indication information, one second indication information corresponds to multiple first indication information. For example, second indication information 1 corresponds to first indication information 1 and first indication information 2.

[0281] Step 705: When receiving the second information indicated by the first indication information sent by the first terminal device, send the second information to the first logical function entity corresponding to the target information interaction, and / or when receiving the third information of the target information interaction 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.

[0282] It should be noted that the execution process of this step can refer to the execution process of step 604 in the above embodiment, with the same principle and will not be elaborated here.

[0283] As a possible implementation, when receiving the second information indicated by the first indication information sent by the first terminal device, the access network device may, according to the correspondence between the second indication information and the first indication information, 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 the third information indicated by the second indication information sent by the first logical function entity, the access network device may, according to the correspondence between the second indication information and the first indication information, send the third information indicated by the first indication information to the first terminal device corresponding to the target information interaction.

[0284] Specifically, when receiving the second information indicated by the first indication information sent by the first terminal device, the access network device may determine the second indication information corresponding to the first indication information according to 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. When receiving the third information of 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 according to 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.

[0285] Among them, the access network device can determine the second indication information corresponding to the first indication information according to the corresponding relationship between the first indication information and the second indication information directly or indirectly. For indirect determination, for example, the access network device determines the target information interaction corresponding to the first indication information according to the corresponding relationship between the first indication information and the target information interaction, and then determines the second indication information corresponding to the target information interaction according to the corresponding relationship between the target information interaction and the second indication information. The access network device can determine the first indication information corresponding to the second indication information according to the corresponding relationship between the first indication information and the second indication information directly or indirectly. For indirect determination, for example, the access network device determines the target information interaction corresponding to the second indication information according to the corresponding relationship between the second indication information and the target information interaction, and then determines the first indication information corresponding to the target information interaction according to the corresponding relationship between the target information interaction and the first indication information.

[0286] It can also be understood that in the case of receiving the second information indicated by the first indication information sent by the first terminal device, the access network device determines the <first logical function entity, second indication information> corresponding to the first indication information according to the corresponding relationship between the first indication information and the <first logical function entity, second indication information>, and sends the second information indicated by the second indication information to the first logical function entity. In the case of receiving the third information indicated by the second indication information sent by the first logical function entity, the access network device determines the first indication information corresponding to the <first logical function entity, second indication information> according to the corresponding relationship between the first indication information and the <first logical function entity, second indication information>, and sends the third information indicated by the first indication information to the first terminal device.

[0287] For the uplink interaction information, the first terminal device generates the relevant service information (the 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 (indicating that the second information corresponds to the first indication information) to the access network device. 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.

[0288] For downlink interaction information, a first logical function entity generates relevant service information (third information) for information interaction of a target service or a target function or a target service. The first logical function entity determines second indication information corresponding to the third information, and sends the third information and the second indication information (indicating that the third information corresponds to the second indication information) to an access network device. After receiving the third information indicated by the second indication information, the access network device may determine first indication information corresponding to <the first logical function entity, the second indication information>, and send the third information indicated by the first indication information to a first terminal device corresponding to the target information interaction.

[0289] 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 further includes the access network device indicating the second indication information (i.e., the first indication information) corresponding to the target information interaction to the first logical function entity.

[0290] Optionally, for uplink interaction information, the access network device forwards relevant service information (such as second information) of information interaction of a service / function / service or information interaction of a logical function entity in a terminal device to the first logical function entity, and indicates second indication information (i.e., the first indication information) corresponding to the forwarded relevant service information to the first logical function entity. The first logical function entity determines information interaction of a service / function / service corresponding to the relevant service information forwarded by the access network device according to the second indication information.

[0291] Optionally, for downlink interaction information, the first logical function entity determines second indication information (i.e., the first indication information) corresponding to relevant service information (such as third information) of a target information interaction generated by the first logical function entity. The first logical function entity indicates the second indication information corresponding to the relevant service information of the target information interaction generated by the first logical function entity to the access network device.

[0292] For the information transmission method provided in this application, when the second indication information is different from the first indication information, the access network device determines the correspondence between the second indication information and the first indication information, so that when receiving the second information indicated by the first indication information sent by the first terminal device, according to the correspondence between the second indication information and the first indication information, the access network device sends the second information to a first logical function entity corresponding to the target information interaction, and / or when receiving the third information of the target information interaction sent by the first logical function entity, according to the correspondence between the second indication information and the first indication information, the access network device sends the third information indicated by the first indication information to a first terminal device corresponding to the target information interaction. Thus, based on the correspondence between the second indication information and the first indication information, the access network device can forward relevant service information of the target information interaction to the corresponding first terminal device or the first logical function entity.

[0293] It should be noted that the above embodiments describe the implementation process of the information transmission method from the perspective of the access network device. The following will describe a possible implementation manner of an information transmission method from the perspective of the first terminal device, Figure 8 which is a schematic flowchart of the information transmission method provided in the sixth embodiment of the present application. Figure 8 As

[0294] shown, the information transmission method may include the following steps: Figure 8 Step 801: Send a first piece of information to the access network device.

[0295] Among them, the first piece of information is used to indicate the initiation of a target information interaction, and the target information interaction includes the information interaction of a target service or a target function or a target service. The target information interaction is the information interaction between the first terminal device and the first logical function entity.

[0296] In some embodiments, the first terminal device may send a first piece of information for indicating the initiation of a target information interaction to the access network device to inform the access network device that the first terminal device is to initiate a target information interaction.

[0297] It should be noted that for other execution processes of this step, reference may be made to the execution process of step 301 in the above embodiments. The principle is the same and will not be elaborated here.

[0298] Step 802: Indicate to the access network device the first indication information corresponding to the target information interaction, and / or obtain the first indication information corresponding to the target information interaction determined by the access network device.

[0299] Among them, the first indication information is used to indicate the second piece of 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 piece of information of the target information interaction sent by the first logical function entity to the first terminal device.

[0300] In some embodiments, the first terminal device may indicate to the access network device the first indication information corresponding to the target information interaction, 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 independently by the access network device, or may be determined independently by the first terminal device, or may be jointly determined by the access network device and the first terminal device. This application does not limit this.

[0301] It should be noted that for other execution processes of this step, reference may be made to the execution process of step 302 in the above embodiments. The principle is the same and will not be elaborated here.

[0302]

[0303] ​The information transmission method provided in this application is such that a first terminal device sends first information to an access network device. Herein, the first information is used to indicate initiating a target information interaction, thereby indicating, to the access network device, a first indication information corresponding to the target information interaction, and / or obtaining the first indication information corresponding to the target information interaction determined by the access network device. The first indication information is used to indicate second information of the target information interaction sent by the first terminal device to a first logical function entity, and / or the first indication information is used to indicate third information of the target information interaction sent by the first logical function entity to the first terminal device. Thus, by allocating indication information for different information interactions, it is possible to avoid defining dedicated RRC information elements or RRC messages in the standard protocol to carry messages for each information interaction, and the protocol design is flexible. At the same time, different first indication information can be allocated for information interactions of different network function instances of the same network function. Therefore, the problem of a UE simultaneously interacting with multiple network functions of the same type can be solved.

[0304] To clearly illustrate the previous embodiment, this embodiment provides another information transmission method. Figure 9 It is a schematic flowchart of the information transmission method provided in the seventh embodiment of this application.

[0305] Similarly, the information transmission method of the embodiments of this application is applied to a first terminal device.

[0306] As Figure 9 shown, the information transmission method may include the following steps:

[0307] Step 901, send first information to the access network device.

[0308] It should be noted that the execution process of this step can refer to the execution process of step 801 in the above embodiment, with the same principle and will not be elaborated here.

[0309] Step 902, indicate to the access network device a first indication information corresponding to the target information interaction, and / or obtain the first indication information corresponding to the target information interaction determined by the access network device.

[0310] As a possible implementation manner, 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. Or, receive the first indication information corresponding to the target information interaction indicated by the access network device (in this case, the first indication information is determined separately by the access network device).

[0311] As another possible implementation manner, the first indication information includes a first type indication information and a first instance indication information, so that the first terminal device can perform at least one of the following:

[0312] Determine the first type indication information in the first indication information corresponding to the target information interaction, and indicate the first type indication information corresponding to the target information interaction to the access network device; or,

[0313] Determine the 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 access network device; or,

[0314] Determine the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction, and indicate the first type indication information and the first instance indication information corresponding to the target information interaction to the access network device; or,

[0315] Receive the first type indication information in the first indication information corresponding to the target information interaction determined by the access network device; or,

[0316] Receive the first instance indication information in the first indication information corresponding to the target information interaction determined by the access network device; or,

[0317] Receive the first type indication information and the first instance indication information in the first indication information corresponding to the target information interaction determined by the access network device.

[0318] It should be noted that for other execution processes of this step, reference can be made to the execution process of step 302 in the above embodiments. The principle is the same and will not be elaborated here.

[0319] Step 903, 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.

[0320] In some embodiments, after determining the first indication information, the first terminal device may send the 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 function entity corresponding to the target information interaction according to the corresponding relationship between the first indication information and the target information interaction. And / or, it may receive the third information indicated by the first indication information sent by the access network device. At this time, since the third information is indicated by the first indication information, the first terminal device can determine that the third information is sent by the first logical function entity corresponding to the target information interaction according to the corresponding relationship between the first indication information and the target information interaction.

[0321] Optionally, when the first terminal device receives the third information indicated by the first indication information sent by the access network device, it may determine the target information interaction corresponding to the third information according to the first indication information.

[0322] It should be noted that for the other execution processes of this step, reference can be made to the execution process of step 403 in the above-mentioned embodiment. The principle is the same and will not be elaborated here.

[0323] In the information transmission method provided by this application, when the first terminal device sends the first information for indicating the initiation of the target information interaction to the access network device, it can 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, so as to 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. Thus, the first terminal device can correspond the first indication information with the relevant service information of the target information interaction, so as to be able to identify and process the relevant service information of the target information interaction. At the same time, different first indication information can be allocated to the information interactions of different network function instances of the same network function, so the problem that the UE interacts with multiple network functions of the same type simultaneously can be solved.

[0324] In this application, the first terminal device can forward the third information to the third logical function entity in the first terminal device. The following will be combined with Figure 10 , to illustrate this process.

[0325] Figure 10 is a schematic flowchart of the information transmission method provided by the eighth embodiment of this application.

[0326] Similarly, the information transmission method of the embodiment of this application is applied to the first terminal device.

[0327] As Figure 10 shown, the information transmission method may include the following steps:

[0328] Step 1001, send the first information to the access network device.

[0329] Step 1002, 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.

[0330] Step 1003, 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.

[0331] It should be noted that for the execution processes of steps 1001-1003, reference can be made to the execution processes of steps 901-903 in the above-mentioned embodiment. The principle is the same and will not be elaborated here.

[0332] Step 1004: Determine the third logical function entity corresponding to the target information interaction within the first terminal device.

[0333] In this application, the UE also includes logical function entities for information interaction of services / functions / services (which can also be understood as including logical function entities of services / functions / services), and each logical function entity within the UE performs one or more services / functions / services. For example, a logical function entity for session management, a logical function entity for sensing, a logical function entity for location / location function, a logical function entity for AI function, a logical function entity for short message function, a logical function entity for UE policy function, a logical function entity for user plane function, and a logical function entity for access management.

[0334] The relationship between the target information interaction and the third logical function entity within the UE is the same as the above-mentioned "relationship between the target information interaction and the first logical function entity".

[0335] Optionally, the first indication information can correspond to one or more of the following: information interaction of one or more services / functions / services, information interaction of one logical function entity, and can also correspond to information interaction of logical function entities within the UE.

[0336] Step 1005: Determine the correspondence between the first indication information and the third logical function entity.

[0337] In some embodiments, the first terminal device can associate the first indication information corresponding to the target information interaction with the third logical function entity corresponding to the target information interaction. Optionally, it can be directly associated or indirectly associated, and this application does not limit this. Indirect association, for example, the first indication information corresponds to the target information interaction, and the target information interaction corresponds to the third logical function entity. Correspondingly, 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 function entity.

[0338] Optionally, the first terminal device can store / apply the correspondence between the first indication information and the third logical function entity. Or, the first terminal device can 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 function entity.

[0339] Optionally, a third logical function entity and a first indication information may be in one-to-one correspondence. For example, the third logical function entity 1 corresponds to the first indication information 1, and the third logical function entity 2 corresponds to the first indication information 2. Optionally, it is also possible that one third logical function entity corresponds to multiple first indication information. For example, in the case where the information interaction of multiple services / functions / services corresponds to one third logical function entity, and the information interaction of one service / function / service corresponds to one first indication information, one third logical function entity corresponds to multiple first indication information. For example, the third logical function entity 1 corresponds to the first indication information 1 and the first indication information 2.

[0340] Step 1006: Send the third information to the third logical function entity according to the correspondence between the first indication information and the third logical function entity, or send the third information to the third logical function entity corresponding to the target information interaction according to the correspondence between the first indication information and the target information interaction.

[0341] Optionally, when sending the third information to the third logical function entity, since the third information is indicated by the first indication information, the first terminal device can directly send the third information to the third logical function entity according to the correspondence between the first indication information and the third logical function entity when the correspondence between the first indication information and the third logical function entity is determined. Or, when the correspondence between the first indication information and the third logical function entity is not determined, the third information can be sent to the third logical function entity corresponding to the target information interaction according to the correspondence between the first indication information and the target information interaction.

[0342] In summary, in this application, in addition to the routing marking function, the first terminal device also includes the following routing control functions:

[0343] 1. The first terminal device determines the third logical function entity corresponding to the target information interaction within the first terminal device;

[0344] Optionally, the access network device may indicate to the first terminal device that target information interaction needs to be performed, so that the first terminal device determines the third logical function entity corresponding to the target information interaction within the first terminal device. Or, the third logical function entity within the first terminal device indicates to the first terminal device that target information interaction needs to be performed.

[0345] 2. The first terminal device determines the first indication information corresponding to the target information interaction;

[0346] 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.

[0347] Optionally, the first terminal device may also receive the first indication information determined by the access network device and indicated to the first terminal device by the access network device, 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.

[0348] 3. The first terminal device determines the correspondence between the first indication information and the third logical function entity;

[0349] 4. The first terminal device indicates to the access network device the first indication information corresponding to the target information interaction;

[0350] The first terminal device indicates to the access network device the first indication information it has determined, 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.

[0351] This step is optional.

[0352] The first terminal device further includes a routing function:

[0353] 5. The first terminal device receives the third information and the first indication information from the access network device, and the first indication information corresponds to the third information;

[0354] The access network device includes a routing marking function for indicating to the first terminal device the first indication information corresponding to the service / function / service related information. For the downlink interaction information, the first logical function entity generates the relevant service information (third information) for the information interaction of the target service or target function or target service, and sends it to the access network device. After receiving the third information, the access network device can determine the first indication information corresponding to the third information, and send the third information indicated by the first indication information to the first terminal device.

[0355] 6. The first terminal device determines the third logical function entity corresponding to the first indication information according to the correspondence between the first indication information and the third logical function entity, and forwards the third information to the third logical function entity.

[0356] The access network device includes a routing function for delivering service / function / service-related information to the corresponding logical function entity within the first terminal device. After receiving the third information indicated by the first indication information, the first terminal device can determine the third logical function entity within the first terminal device corresponding to the first indication information, and send the third information to the third logical function entity within the first terminal device. The routing function of the first terminal device can determine the third logical function entity within the first terminal device corresponding to the first indication information directly or indirectly. Indirect determination, for example, the first terminal device determines the target service or target function or target service corresponding to the first indication information according to the correspondence between the first indication information and the target information interaction, and then determines the third logical function entity within the first terminal device corresponding to the target service or target function or target service according to the correspondence between the target information interaction and the third logical function entity within the first terminal device.

[0357] In the information transmission method provided in this application, the first terminal device determines the third logical function entity corresponding to the target information interaction within the first terminal device, thereby determining the correspondence between the first indication information and the third logical function entity. Furthermore, according to the correspondence between the first indication information and the third logical function entity, the third information is sent to the third logical function entity, or according to the correspondence between the first indication information and the target information interaction, the third information is sent to the third logical function entity corresponding to the target information interaction. Thus, the first terminal device can send the third information to the third logical function entity corresponding to the target information interaction according to the correspondence between the first indication information and the third logical function entity, or the correspondence between the first indication information and the target information interaction.

[0358] It should be noted that in this application, the first terminal device can also determine the first indication information without sending the first information for indicating the initiation of the target information interaction to the access network device. The following combines Figure 11 , to illustrate this process.

[0359] Figure 11 is a schematic flowchart of the information transmission method provided in the ninth embodiment of this application.

[0360] As Figure 11 shown, the information transmission method may include the following steps:

[0361] Step 1101, indicating to the access network device the first indication information corresponding to the target information interaction, and / or obtaining the first indication information corresponding to the target information interaction determined by the access network device.

[0362] Among them, the target information interaction includes the information interaction of a target service or a target function or a target service, and the target information interaction is the information interaction between the first terminal device and the first logical function entity.

[0363] It should be noted that the explanations of "target information interaction", "first logical function entity", and "target service or target function or target service" in this step can refer to the description of step 301 in the above embodiment, and will not be elaborated here.

[0364] 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.

[0365] In some embodiments, the first terminal device may 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. That is, the first indication information may be determined independently by the access network device, or may be determined independently by the first terminal device, or may be jointly determined by the access network device and the first terminal device. This application does not limit this.

[0366] It should be noted that the other execution processes of this step can refer to the execution process of step 302 in the above embodiment, with the same principle, and will not be elaborated here.

[0367] In the information transmission method provided by this application, the first terminal device sends the first information to the access network device, where the first information is used to indicate the initiation of the target information interaction, so as to 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, where 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. Thus, by allocating the indication information for different information interactions, it is possible to avoid defining dedicated RRC information elements or RRC messages in the standard protocol to carry messages for each information interaction, and the protocol design is flexible. At the same time, different first indication information can be allocated to the information interactions of different network function instances of the same network function, so the problem of the UE simultaneously interacting with multiple network functions of the same type can be solved.

[0368] Optionally, in this application, the first terminal device may also determine the first indication information without sending the first information for instructing to initiate the target information interaction to the access network device, and 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. The following combines Figure 12 , and describes this process.

[0369] Figure 12 is a schematic flowchart of an information transmission method provided in the fourteenth embodiment of this application.

[0370] As Figure 12 shown, the information transmission method may include the following steps:

[0371] Step 1201, 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.

[0372] It should be noted that the execution process of this step may refer to the execution process of step 1101 in the above embodiment, with the same principle, and will not be elaborated here.

[0373] Step 1202, 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.

[0374] It should be noted that the execution process of this step may refer to the execution process of step 903 in the above embodiment, with the same principle, and will not be elaborated here.

[0375] The information transmission method provided in this application, in the case of sending the first information for instructing to initiate the target information interaction to the access network device, by 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, so as to 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. Thus, the first terminal device can correspond the first indication information with the relevant service information of the target information interaction, so as to be able to identify and process the relevant service information of the target information interaction. At the same time, different first indication information can be allocated to the information interactions of different network function instances of the same network function, so the problem that the UE interacts with multiple network functions of the same type simultaneously can be solved.

[0376] The following combines Figure 13 , and describes a possible implementation manner of an information transmission method from the perspective of the first logical function entity. Figure 13It is a schematic flowchart of the information transmission method provided in the eleventh embodiment of the present application.

[0377] As Figure 13 shown, the information transmission method may include the following steps:

[0378] Step 1301, send the first information to the access network device.

[0379] Among them, the first information is used to indicate the initiation of target information interaction, and the target information interaction includes the information interaction of the target service or the target function or the target service. The target information interaction is the information interaction between the first terminal device and the first logical function entity, and the target information interaction corresponds to the first indication information.

[0380] 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 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.

[0381] It should be noted that the explanation of the "first indication information" in this step can refer to the description of step 302 in the above embodiment, and will not be elaborated here.

[0382] In some embodiments, the first logical function entity may send the first information for indicating the initiation of the target information interaction to the access network device to inform the access network device that the first logical function entity is to initiate the target information interaction.

[0383] It should be noted that when the first logical function entity sends the first information for indicating the initiation of the target information interaction to the access network device, it will indicate to the access network device that the first terminal device is the one that performs the target information interaction with the first logical function entity.

[0384] It should be noted that the other execution processes of this step can refer to the execution process of step 301 in the above embodiment, and the principle is the same, and will not be elaborated here.

[0385] In the information transmission method provided by this application, a first logical function entity may send first information to an access network device, where the first information is used to indicate the initiation of a target information interaction. The target information interaction includes the information interaction of a target service, a target function, or a target service. The target information interaction is the information interaction between a first terminal device and the first logical function entity, and the target information interaction corresponds to first indication information. The first indication information is used to indicate 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 third information of the target information interaction sent by the first logical function entity to the first terminal device. Thus, by allocating indication information for different information interactions, it is possible to avoid defining dedicated RRC information elements or RRC messages for each information interaction in the standard protocol to carry messages, and the protocol design is flexible. At the same time, different first indication information can be allocated to the information interactions of different network function instances of the same network function. Therefore, the problem that the UE simultaneously interacts with multiple network functions of the same type can be solved.

[0386] It should be noted that in this application, the first logical function entity may also send third information of the target information interaction to the access network device, and / or receive second information of the target information interaction sent by the access network device to implement the target information interaction with the first terminal device. The following combines Figure 14 to illustrate this process.

[0387] Figure 14 is a schematic flowchart of the information transmission method according to the twelfth embodiment of this application.

[0388] Similarly, the information transmission method of the embodiment of this application is applied to the first logical function entity.

[0389] As Figure 14 shown, the information transmission method may include the following steps:

[0390] Step 1401: Send first information to the access network device.

[0391] It should be noted that the execution process of this step may refer to the execution process of step 1101 in the above embodiment, and the principle is the same, so it will not be elaborated here.

[0392] Step 1402: Send third information of the target information interaction to the access network device, and / or receive second information of the target information interaction sent by the access network device.

[0393] In some embodiments, the first logical function entity may generate relevant service information (third information) for the information interaction of a target service or a target function or a target service, and send the third information of the target information interaction to the access network device, so that the access network device forwards the third information to the first logical function entity. And / or, the first logical function entity may receive the second information of the target information interaction sent by the access network device from the first terminal device.

[0394] It should be noted that for the other execution processes of this step, reference may be made to the execution process of step 403 in the above embodiments. The principle is the same and will not be elaborated here.

Thereby, the first logical function entity realizes target information interaction with the first terminal device.

[0396] In this application, a second indication information may also be allocated for the target information interaction. The following will be combined with Figure 15 , and this process will be described from the perspective of the first logical function entity.

[0400] It should be noted that for the execution process of this step, reference may be made to the execution process of step 1101 in the above embodiments. The principle is the same and will not be elaborated here.

[0401] Step 1502, 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.

[0402] In some embodiments, the first logical function entity may 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. That is, the second indication information may be determined independently by the access network device, or may be determined independently by the first logical function entity, or may be jointly determined by the access network device and the first logical function entity. This application does not limit this.

[0403] It should be noted that for other execution processes of this step, reference can be made to the execution process of step 603 in the foregoing embodiments. The principle is the same and will not be elaborated here.

That is, the second indication information may be determined independently by the access network device, or may be determined independently by the first logical function entity, or may be jointly determined by the access network device and the first logical function entity. This application does not limit this.

[0417] It should be noted that the other execution processes of this step can refer to the execution process of step 603 in the above embodiments. The principles are the same and will not be repeated here.

Thus, the first logical function entity can correspond the second indication information with the relevant service information of the target information interaction, so as to be able to identify and process the relevant service information of the target information interaction. At the same time, different second indication information can be allocated to the information interactions of different services / functions / services of the same network function, so the problem of the UE simultaneously performing information interactions of multiple services / functions / services with the same network function can be solved.

[0430] Regarding Figure 18 the schematic flowchart shown, the following embodiments exist:

[0431] Embodiment 1:

[0432] The UE indicates to the access network that target information interaction needs to be performed.

[0433] 1) The UE indicates to the access network that target information interaction needs to be performed, and the access network determines the target logical function entity for the target information interaction.

The UE determines that the target logical function entity within the UE corresponding to the sensing-related information interaction, such as processing entity 2, corresponds to the first indication information 004. The UE generates the second information for the sensing-related information interaction. The UE determines that the second information corresponds to the first indication information 004 corresponding to the sensing-related information interaction. The UE sends the second information to the access network, indicating that the second information corresponds to 004. The access network determines the target logical function entity SF1 corresponding to the first indication information 004, and forwards the second information corresponding to the first indication information to SF1. The access network also determines the second indication information 01 corresponding to the first indication information 004, and indicates to the target logical function entity SF1 that the second information corresponds to the second indication information 01. The target logical function entity SF1 determines that the sensing-related information interaction corresponding to the second information corresponds to the second indication information 01. The target logical function entity SF1 generates the third information for the target sensing-related information interaction, and sends the third information to the access network. The target logical function entity SF1 determines, according to the second indication information 01 corresponding to the sensing-related information interaction, that the second indication information corresponding to the third information is 01, and indicates to the access network that the third information corresponds to the second indication information 01. The access network determines the first indication information 004 corresponding to <target logical function entity SF1, second indication information 01>, and forwards the third information to the UE, indicating that the third information corresponds to the first indication information 004. The UE determines the target logical function entity within the UE corresponding to the first indication information 004, such as processing entity 2, and delivers the third information to the processing entity 2 within the UE.

[0474] In this embodiment, when the second indication information and the first indication information are the same indication information, it is not necessary for the access network to determine the second indication information corresponding to the target information interaction (in step 3), it is not necessary for the access network to further determine the correspondence between the first indication information and the second indication information (in step 4), it is not necessary for the access network to further determine the second indication information corresponding to the first indication information according to the correspondence between the first indication information and the second indication information (in step 9), and it is not necessary for the access network to determine the first indication information corresponding to <target logical function entity, second indication information> (in step 12).

[0476] The target logical function entity instructs the access network that it is necessary to perform target information interaction with the UE.

[0477] 1) The target logical function entity instructs the access network that it is necessary to perform target information interaction with the UE. For example, logical function entity 1 needs to perform information interaction related to the measurement report of data 1 with the UE. Logical function entity 1 instructs the access network that it is necessary to perform information interaction related to the measurement report of data 1 with the UE. The access network determines that the target logical function entity is logical function entity 1. Optionally, the target logical function entity sends the third information of the target information interaction to the access network. For example, logical function entity 1 sends the third information of the information interaction related to the measurement report of data 1 to the access network.

[0478] 2) The same as 2) in Embodiment 1.

[0479] 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 logical function entity 1.

[0480] 4) The access network instructs the UE that the target information interaction corresponds to the first indication information.

The access network determines the logical function entity 2 corresponding to the first indication information 002, and forwards the second information corresponding to the first indication information to logical function entity 2. Logical function entity 2 generates new third information related to the information interaction related to the measurement reporting of data 2, and sends the new third information to the access network. The access network determines the first indication information 002 corresponding to 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 in 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 in the UE.

[0489] Optionally, logical function entity 1 needs to interact with the UE for target information for the information interaction related to the measurement reporting of data 3.

For example, the second indication information corresponding to the information interaction related to the measurement report of Data 1 allocated by the access network is 01.

[0494] 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 the 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. 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 <logical function entity 1, 01>.

[0499] 11) The target logical function entity generates new third information for target information interaction and sends the new third information to the access network. For example, if logical function entity 1 needs to interact with the UE regarding information related to the measurement report of data 1, logical function entity 1 generates new third information for the information interaction related to the measurement report of 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 according to the second indication information corresponding to the target information interaction, and indicates the second indication information corresponding to the new third information to the access network. For example, logical function entity 1 determines 01 corresponding to the new third information for the information interaction related to the measurement report of data 1 according to 01 corresponding to the information interaction related to the measurement report of data 1, and indicates 01 corresponding to the new third information to the access network.
