[0157] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0158] In the embodiments of the present application, the term "at least one" means at least one, the term "plurality" means two or more, and other quantifiers are similar.

[0159] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0160] The embodiments of the present application provide a communication method, an apparatus, and a storage medium to reduce the development complexity of gNB-CU-CP.

[0161] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0162] The technical solution provided in the embodiment of the present application can be applied to a variety of systems, for example, long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, long term evolution advanced (LTE-A) system, evolved packet system (EPS), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) system, 5G new radio (NR) system and its evolved communication system, 5G core network (5GC), 5G system (5GS), 6G system and its evolved communication system, etc. These various systems may include terminals and network devices.

[0163] The 5G system architecture contains a set of network functions (NFs). NF is a processing function in the system, which defines functional behaviors and interfaces. NF can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, such as on a cloud infrastructure. The 5G system architecture is defined as a service-based architecture, that is, a system architecture that implements system functions by providing services to other authorized NFs to access their services through a set of NFs. NF service is a function that NF (as NF service producer) exposes to other authorized NFs (as NF service consumers) through a service-based interface. An NF service can support at least one NF service operation. An NF can provide different NF services.

[0164] The network functions in the embodiments of the present application can be implemented as network elements on dedicated hardware, or as software instances running on dedicated hardware, or as virtualized functions instantiated on a platform, such as on a cloud infrastructure. The network functions used to carry radio access network related functions can also be called radio network functions, base station logical nodes, base station logical function entities or radio access network network elements.

[0165] The network functions and terminals in the embodiments of the present application can also be understood as logical functional entities or logical nodes in the system.

[0166] Network equipment is equipment that implements network functions, and network equipment may include access network equipment and core network equipment. Terminals are equipment that implement terminal functions.

[0167] In the embodiment of the present application, the interaction between two network functions, that is, network function A sends information to network function B or network function B receives information sent by network function A, can be based on a service-based interface of network function A and / or network function B, or based on a point-to-point interface between network function A and network function B.

[0168] In the embodiment of the present application, the terminal sends information to the network side device or similar descriptions, indicating that the intended recipient of the information sent by the terminal is the network device. The terminal can send information directly to the network device, or indirectly to the network device through another device. In the embodiment of the present application, the network side device sends information to the terminal or similar descriptions, indicating that the intended recipient of the information sent by the network device is the terminal. The network device can send information directly to the terminal, or indirectly to the terminal through another device.

[0169] In the embodiment of the present application, the channel may also be replaced by a service or an association.

[0170] In the embodiment of the present application, the terminal identifiers in different information may be the same identifier or different identifiers of the same terminal.

[0171] Combine the following Figure 1 The communication scenario of this application is described. Figure 1 A schematic diagram of the architecture of a communication system provided in an embodiment of the present application.

[0172] like Figure 1 As shown in the figure, the architecture may include terminals, access network equipment, core network equipment and data network (DN) parts. Among them, terminals, access network equipment and core network equipment are the main parts of the architecture. Logically, access network equipment and core network equipment can be divided into two parts: user plane and control plane. The control plane is responsible for the management of mobile networks, and the user plane is responsible for the transmission of service data.

[0173] Core network equipment may also be called core network element or core network functional entity.

[0174] The access network device may be a base station.

[0175] In 5G, a gNB can be composed of a gNB central unit (CU) and at least one gNB-DU. The gNB-CU and gNB-DU are connected through the F1 interface. Figure 2 As shown in the figure, in the architecture where the user plane and control plane of the gNB-CU are separated, a gNB can be composed of a gNB-CU-CP, multiple gNB-CU-UPs and multiple gNB-DUs. The gNB-CU-CP is connected to the gNB-DU through the F1-C interface, and the gNB-CU-UP is connected to the gNB-DU through the F1-U interface. The gNB-CU-UP is connected to the gNB-CU-CP through the E1 interface. Under the control of the same gNB-CU-CP, a gNB-DU can be connected to multiple gNB-CU-UPs, and a gNB-CU-UP can be connected to multiple gNB-DUs.

[0176] The gNB-CU hosts the RRC, service data adaptation protocol (SDAP) and PDCP of the gNB, and supports terminal radio access control, terminal connection control / management, radio bearer control, mobility management, paging and other functions.

[0177] The gNB-DU carries the radio link control (RLC), media access control (MAC) and physical layer of the gNB, and some of its operations are controlled by the gNB-CU.

[0178] The gNB-CU-CP carries the control plane part of RRC and PDCP of gNB-CU, and supports radio resource management related functions, such as terminal radio access control, terminal connection control / management, radio bearer control, mobility management, and paging. The gNB-CU-UP carries the user plane part of PDCP of gNB-CU and SDAP.

[0179] Since the existing RAN carries all control plane functions by the same logical node gNB-CU-CP, the development complexity of gNB-CU-CP is high, resulting in slow base station service launch. In addition, gNB-CU-CP includes radio connection management functions, radio bearer management functions, etc. When any of these functions needs to be updated, the entire gNB-CU-CP needs to be updated, which makes service updates complicated.

[0180] In addition, for future 6G scenarios, there may be differentiated requirements for wireless connection management functions and terminal user plane data transmission management functions. For example, in the interaural fusion scenario, there may be no need to support terminal user plane data transmission, but support for terminal wireless connection management is required. In this case, the network can only deploy gNB-CU-CP that includes both terminal wireless connection management functions and terminal user plane data transmission management functions, resulting in high costs.

[0181] Based on the problems in the prior art, the present application proposes the following technical concept: decoupling the control plane function in the RAN to obtain the first network function and other control plane network functions, and the first network function can realize the function of controlling or managing the transmission of terminal user plane data through the RAN by interacting with other control plane network functions. Since the first network function is separated from other control plane network functions in the RAN, the development complexity of the first network function and other control plane network functions in the RAN is reduced compared with the existing gNB-CU-CP that includes all RAN control plane functions, and the independent development of each network function can further speed up the launch of base station services; in addition, since the first network function is separated from other control plane network functions in the RAN, only the first network function can be updated without affecting other control plane network functions in the RAN, making service updates easy. In addition, the control plane functions in the RAN can be deployed on demand, reducing the cost of network deployment.

[0182] The solution provided in this application is introduced below in conjunction with specific embodiments.

[0183] It should be noted that, in the embodiment of the present application, information of the same sender or receiver can be sent in the same message or in different messages. The request information can also be replaced by indication information, command information or control information.

[0184] Figure 3 A communication method according to an embodiment of the present invention is provided. Figure 1 .like Figure 3 As shown, the method includes:

[0185] S301. A first network function obtains relevant information of a user plane data transmission channel of a terminal.

[0186] The user plane data transmission channel is carried on at least one first channel and / or at least one second channel. That is, the user plane data in a user plane data transmission channel can be transmitted by at least one first channel and / or at least one second channel.

[0187] The at least one first channel may be a channel between the terminal and the RAN for transmitting user plane data of the terminal. That is, the first channel may be a channel between the terminal and a network function in the RAN for transmitting user plane data of the terminal.

[0188] At least one second channel is a channel between the RAN and the core network for transmitting user plane data of the terminal. That is, the second channel can be a channel between a network function in the RAN for transmitting user plane data of the terminal and a network function in the core network for transmitting user plane data of the terminal.

[0189] The user plane data of the terminal may refer to data transmitted through a user plane data transmission channel from the terminal or the terminal as a receiving end.

[0190] The user plane data of the terminal includes at least the following: data between the terminal and the data network, perception data from the terminal or the terminal as a receiving end, and data between the terminal and the network function.

[0191] The first channel can be any one of the following: wireless bearer, data / service wireless bearer, RLC bearer, data / service RLC bearer, RLC channel, data / service RLC channel, logical channel, data / service logical channel, transport channel, data / service transport channel, physical channel, data / service physical channel, or a bearer after reorganization / reconstruction of the above bearers, or a channel after reorganization / reconstruction of the above channels.

[0192] The user plane data transmission channel may be a session (eg, a protocol data unit (PDU) session). A session is an association between a terminal and a data network or between a terminal and a network function in a system for providing a data connection service.

[0193] The number of user plane data transmission channels of the terminal may be one or more.

[0194] In a possible implementation, the first network function may obtain relevant information about the user plane data transmission channel of the terminal by receiving information sent by other network functions; the first network function may also determine relevant information about the user plane data transmission channel of the terminal by itself.

[0195] The other network function may be a network function in the core network for controlling or managing a user plane data transmission channel. The other network function may interact directly or indirectly with the first network function. Indirect interaction refers to forwarding through at least one network function other than the other network function and the first network function.

[0196] Exemplarily, the first network function may determine relevant information of a user plane data transmission channel of the terminal when determining that a second network function used to transmit user plane data of the terminal needs to be changed.

[0197] In one possible implementation, the relevant information of the user plane data transmission channel of the terminal may include at least one of the following: an identifier of the user plane data transmission channel, quality of service (QoS) information of the user plane data transmission channel, address information or identification information of at least one second channel peer, and security parameters of the user plane data transmission channel.

[0198] The second channel peer end may refer to a peer end relative to the RAN, that is, the second channel peer end may be a network function in the core network for transmitting user plane data of the terminal.

[0199] The first network function may be a network function in the RAN for controlling or managing a user plane data transmission channel.

[0200] The control plane function of the RAN may be implemented by multiple network functions, including the first network function.

[0201] The first network function may carry / support / include at least one of the following functions: controlling establishment / modification / release / deletion of the first channel, and controlling establishment / modification / release / deletion of the second channel in the RAN.

[0202] The first network function controls establishment / modification / release / deletion of the second channel in the RAN, which may be understood as the first network function controls establishment / modification / release / deletion of the second channel in at least one second network function.

[0203] It can be understood that the name of the first network function is only an example, and other network functions / services having the same function as the first network function can be included in the scope of the first network function in the embodiment of the present application.

[0204] Exemplarily, the first network function may also be called a wireless user plane transmission management function, a wireless user plane transmission control function, a wireless bearer management function, a wireless bearer control function, a wireless session management function, a wireless session control function, a wireless session resource management function or a wireless session resource control function.

[0205] It should be noted that, in addition to supporting the functions supported by the above-mentioned first network function, RAN also needs to support other functions, such as terminal mobility management, control plane data transmission, paging network functions, and other functions related to user plane data transmission. The functions supported by the above-mentioned first network function are the functions at least supported by the first network function, and it is not excluded that the first network function also carries / supports / includes other RAN functions.

[0206] The first network function and the network function that carries out terminal wireless connection control or management are logically independent network functions.

[0207] S302: The first network function sends first request information to at least one second network function according to relevant information of a user plane data transmission channel of the terminal.

[0208] In other words, the second network function receives the first request information sent by the first network function.

[0209] The first request information may be used to instruct to perform an operation on at least one first channel and / or at least one second channel.

[0210] The operation includes at least one of the following: create, modify, release, delete.

[0211] The first network function may send the same first request information to the at least one second network function, or may send different first request information to the at least one second network function.

[0212] In one possible implementation, the first request information may include at least one of the following: an identifier of the terminal, relevant information of the first channel, relevant information of the second channel, relevant information of part or all of the user-plane data transmission channel, an identifier of the first channel context, an identifier of the second channel context, an identifier of the user-plane data transmission channel context, and an associated identifier.

[0213] The related information of the first channel may include at least one of the following: an identifier of at least one first channel, and a value of a related parameter of at least one first channel.

[0214] The relevant information of the first channel may refer to relevant information for establishing the first channel, or modifying relevant information of the first channel, or releasing relevant information of the first channel, or deleting relevant information of the first channel.

[0215] Among them, establishing the relevant information of the first channel or modifying the relevant information of the first channel may include at least one first channel identifier and at least one first channel related parameter value; releasing the relevant information of the first channel or deleting the relevant information of the first channel may include at least one first channel identifier.

[0216] The relevant parameters of the first channel include at least one of the following: security parameters of the first channel, QoS parameters of the first channel, mapping rules of user plane data of the terminal to the first channel, PDCP configuration, and address information or identification information of the first channel of the network function used for terminal user plane transmission in the RAN.

[0217] The mapping of the user plane data of the terminal to the first channel may be a mapping of the user plane data transmission channel of the terminal to the first channel, or a mapping of the minimum QoS granularity of the user plane data transmission channel of the terminal to the first channel.

[0218] The minimum QoS granularity of the user plane data transmission channel of the terminal is, for example, a QoS flow. A user plane data transmission channel may include QoS flows of different data transmission QoS.

[0219] The relevant information of the second channel may include at least one of the following: an identifier of at least one second channel, and a value of a relevant parameter of at least one second channel.

[0220] The relevant parameters of the second channel may include address information or identification information of the peer end of the second channel.

[0221] The relevant information of the second channel may refer to the relevant information of establishing the second channel, or modifying the relevant information of the second channel, or releasing the relevant information of the second channel, or deleting the relevant information of the second channel.

[0222] In a possible manner, the information related to releasing / deleting the first channel and the information related to releasing / deleting the second channel are the same information.

[0223] The identifier of the first channel context is used to identify the first channel context of the terminal.

[0224] The identifier of the second channel context is used to identify the second channel context.

[0225] The identifier of the user plane data transmission channel context is used to identify the user plane data transmission channel context of the terminal.

[0226] The associated identifier is used to identify the association between the first network function and the second network function, and the association is used to support the first channel and / or the second channel of the terminal, or the association is used to support the user plane data transmission channel of the terminal.

[0227] In a possible implementation manner, after acquiring relevant information of the user plane data transmission channel of the terminal, the first network function can determine relevant information of the first channel and / or relevant information of the second channel according to the relevant information of the user plane data transmission channel of the terminal.

[0228] The second network function may be a network function in the RAN used to transmit user plane data of the terminal.

[0229] The second network function can carry at least one of the following functions: RLC function, MAC function, part or all of the physical layer function, data encryption / decryption, integrity protection / verification, function of mapping user plane data to the first channel, and function of carrying and processing sub-channels related to the first channel.

[0230] In the embodiment of the present application, the functions that can be carried by the second network function are not limited. Exemplarily, the second network function can also be used to transmit control plane data of the terminal.

[0231] In the case of multiple second network functions, different second network functions include different functions, for example, different network functions include different terminal user plane data transmission protocol functions.

[0232] It can be understood that the name of the second network function is only an example, and other network functions / services having the same function as the second network function can be included in the scope of the second network function in the embodiments of the present application.

[0233] S303: Each second network function performs an operation on at least one first channel and / or at least one second channel according to the first request information.

[0234] The operation may include at least one of the following: create, modify, release, delete.

[0235] Performing an operation on at least one first channel includes: performing an operation on at least one first channel-related processing entity and / or sub-channel in the second network function.

[0236] For example, the first channel-related processing entities may include at least one of the following: a PDCP entity, an SDAP entity, an RLC entity, a MAC entity, a physical layer (PHY) entity, or an entity including the processing functions reorganized / reconstructed from the processing functions included in the above entities.

[0237] Exemplarily, the sub-channels related to the first channel may include at least one of the following: an RLC bearer, a data / service RLC bearer, an RLC channel, a data / service RLC channel, a logical channel, a data / service logical channel, a transport channel, a data / service transport channel, a physical channel, a data / service physical channel, or a bearer after reorganization / reconstruction of the above bearers, or a channel after reorganization / reconstruction of the above channels.

[0238] Performing an operation on at least one second channel includes: performing an operation on at least one second channel-related processing entity and / or subchannel in the second network function.

[0239] After receiving the first request information, the second network function applies / releases / deletes the values ​​of the relevant parameters of the first channel by the processing entity and / or sub-channel related to the first channel, or the second network function determines the values ​​of the relevant parameters of the processing entity and / or sub-channel related to the first channel based on the values ​​of the relevant parameters of the first channel.

[0240] After receiving the first request information, the second network function stores / applies / modifies / releases / deletes the values ​​of the relevant parameters of the second channel.

[0241] In a possible implementation manner, after each second network function performs an operation on at least one first channel and / or at least one second channel, it may send first response information to the first network function.

[0242] In other words, the first network function receives first response information sent by at least one second network function.

[0243] The first response information may include at least one of the following items: at least one first channel operation success or failure information, address information or identification information of at least one second network function in its corresponding first channel, address information or identification information of the at least one second network function in its corresponding second channel, at least one second channel operation success or failure information, an identifier of the first channel context, an identifier of the second channel context, an identifier of the user plane data transmission channel context, and an associated identifier.

[0244] The address information or identification information of the same second network function in the corresponding first channel may be the same as or different from the address information or identification information of the same second network function in the corresponding second channel.

[0245] exist Figure 3 In the illustrated embodiment, the first network function in the RAN obtains relevant information of the user plane data transmission channel of the terminal, and sends a first request information to at least one second network function based on the relevant information of the user plane data transmission channel; after receiving the first request information, the second network function performs an operation on at least one first channel and / or at least one second channel based on the first request information. Since the first network function is separated from other network functions in the RAN, the development complexity of the first network function is reduced, and the independent development of each network function can further speed up the launch of base station services; in addition, since the first network function is separated from other control plane network functions in the RAN, only the first network function can be updated without affecting other control plane network functions in the RAN, making service updates easy. In addition, the control plane functions in the RAN can be deployed on demand, reducing the cost of network deployment.

[0364] Based on any of the above embodiments, Fig.11A and Fig. 11B Describes in detail how network functions interact with each other.

[0365] There are two modes of interaction between two network functions: service-based interaction and reference point-based interaction. The two modes of interaction can exist separately or simultaneously.

[0366] For the simultaneous existence scenario, for example, the third network function may send the first information to the first network function via a service-based interface, and the third network function may also send the second information to the first network function via a point-to-point interface.

[0367] For the service-based interaction mode, the first network function allows other authorized network functions to access its services, and the first network function can access the services authorized by other network functions.

[0368] Based on the reference point interaction mode, two network functions can interact through a point-to-point interface between the two network functions.

[0369] The first network function interacts with other network functions using a service-based interface. The schematic diagram of the interaction is as follows: Fig.11A As shown, the first network function provides services to the service consumer (eg, the second network function) through the service-based interface Nx. The embodiment of the present application does not limit the names of the various interfaces, and the names of the various interfaces can be replaced with other names.

[0370] The first network function can interact with other network functions based on the reference point. The schematic diagram of the interaction is as follows: Fig. 11B As shown, there is an Nxy reference point between the first network function and the second network function.

[0371] Service-based interfaces and reference points are two different ways of modeling interactions between architectural entities. A reference point can be replaced by at least one service-based interface that provides equivalent functionality. For example, Fig. 11B The Nxy reference point in may be replaced by an Nx service-based interface providing equivalent functionality, or the Nxy reference point may be replaced by an Nx service-based interface providing equivalent functionality and a service-based interface for a second network function.

[0372] In the service-based architecture, the first network function, the second network function, and the terminal provide the following services respectively:

[0373] The first network function provides at least one of the following services or service operations to other networks: establishing / modifying / releasing / deleting a terminal context, and establishing / modifying / releasing / deleting user plane data transmission resources of a terminal.

[0374] The second network function provides at least one of the following services or service operations: establishing / modifying / releasing / deleting the first channel, and establishing / modifying / releasing / deleting the second channel.

[0375] The terminal provides the following services or service operations: establishing / modifying / releasing / deleting the first channel.

[0376] The first network function, other network functions (such as the second network function and the fourth network function), and the terminal respectively perform the following operations based on the service interface:

[0377] Other network functions may send request information to the first network function through the service-based interface of the first network function; the first network function may send response information to other network functions through its service-based interface.

[0378] The first network function may send request information to the second network function through the service-based interface of the second network function. The first network function may receive response information through the service-based interface of the second network function.

[0379] The first network function may send indication information to the terminal through a service-based interface of the terminal. The first network function may receive response information through a service-based interface of the terminal.

[0380] The point-to-point interface between the first network function and other network functions, and between the first network function and the terminal may perform the following operations:

[0381] The other network functions may send request information to the first network function through a point-to-point interface with the first network function. The first network function may send response information through a point-to-point interface with other network functions.

[0382] The first network function may send request information to the second network function through a point-to-point interface with the second network function, and the first network function may receive response information through a point-to-point interface with the second network function.

[0383] The first network function sends indication information to the terminal through a point-to-point interface with the terminal. The first network function receives response information through a point-to-point interface with the terminal.

[0384] Note: Service-based interfaces and point-to-point interfaces can be used simultaneously in the system to exchange the above different information.

[0385] Based on any of the above embodiments, specific examples are given below to illustrate the communication process of the present application.

[0386] It should be noted that, in the following examples, RAN may include other network functions in addition to the network functions shown; the network functions shown may include other functions in addition to the functions shown.

[0387] Example 1: RAN includes a first network function, a second network function 1 and a fourth network function.

[0388] The channel for transmitting the user plane data of the terminal between the second network function 1 and the terminal is the first channel. The user plane data of the terminal can be directly exchanged between the second network function 1 and the network function used for transmitting the user plane data of the terminal in the core network, and the channel for transmitting the user plane data of the terminal between them is the second channel.

[0389] The interaction between the first network function, the second network function 1 and the fourth network function may be expressed in a reference point manner, such as Fig. 12A As shown; it can also be based on a service-based representation, such as Fig. 12BAs shown; you can also use both methods at the same time, such as Fig. 12C shown.

[0390] The process of controlling or managing the transmission of user plane data of the terminal through the RAN is as follows. The manner in which network functions interact with each other in the following process is not limited, for example, interaction can be performed through a point-to-point interface between network functions, or interaction can be performed through a service-based interface of each network function.

[0391] 1. When the terminal needs to transmit user plane data of the terminal, the terminal first needs to have a wireless connection, that is, the terminal is connected to the RAN. If the terminal does not currently establish a wireless connection, the terminal requests the fourth network function to establish a wireless connection. The terminal and the fourth network function complete the establishment of the wireless connection.

[0392] 2. The fourth network function sends a request message for establishing a terminal context (fourth request message) to the first network function. The fourth network function indicates at least one of the following in the request message: the identifier of the terminal, the identifier or address of the second network function 1, and the associated identifier. The first network function establishes the terminal context and stores / applies the identifier or address of the second network function 1. The first network function sends a response message for establishing a terminal context (fourth response message) to the fourth network function. The response message may indicate at least one of the following: successful establishment of the terminal context or failure to establish the terminal context, and the associated identifier.

[0393] 3. When the first network function receives the second request information, the second request information is used to request the establishment / modification / release / deletion of the user plane data transmission resources of the terminal, and the second request information indicates at least one of the following: the terminal identifier, the user plane data transmission channel related information of the terminal, the user plane data transmission channel context identifier, and the associated identifier. The user plane data transmission channel related information of the terminal includes at least one of the following: the user plane data transmission channel identifier, the QoS information of the user plane data transmission channel, the address information or identification information of the second channel peer, and the user plane data transmission channel security parameters. The user plane data transmission channel of the terminal may be a PDU session. The first network function needs to control the establishment / modification / release / deletion of the first channel, and control the establishment / modification / release / deletion of the second channel in the RAN. The first channel is, for example, a data radio bearer.

[0394] The first network function determines, based on the second request information, the relevant information for establishing / modifying / releasing / deleting the first channel, and / or the relevant information for establishing / modifying / releasing / deleting the second channel. The relevant information for establishing / modifying / releasing / deleting the first channel includes at least one of the following: an identifier of at least one first channel, a value of a relevant parameter of at least one first channel. The value of the relevant parameter of at least one first channel includes a value of a QoS parameter of at least one first channel, a mapping rule of user plane data of the terminal to at least one first channel, and a value of a security parameter of at least one first channel. The relevant information for establishing / modifying / releasing / deleting the second channel may include at least one of the following: an identifier of at least one second channel, a value of a relevant parameter of at least one second channel. The relevant parameters of the second channel include address information or identification information of the opposite end of the second channel. The first network function determines the value of the QoS parameter of at least one first channel and the mapping rule of user plane data of the terminal to at least one first channel based on the QoS information of the user plane data transmission channel. The first network function determines the value of the security parameter of at least one channel based on the security parameter of the user plane data transmission channel.

[0395] 4. The first network function sends a first request message to the second network function 1, where the first request message indicates that an operation is to be performed on at least one first channel and at least one second channel, where the operation includes at least one of the following: establishment, modification, release, and deletion.

[0396] The first request information may include at least one of the following: an identifier of the terminal, relevant information of the first channel, relevant information of the second channel, relevant information of part or all of the user-plane data transmission channel, an identifier of the first channel context, an identifier of the second channel context, an identifier of the user-plane data transmission channel context, and an associated identifier.

[0397] The second network function 1 establishes / modifies / releases / deletes the processing entity and / or subchannel related to the first channel according to the first request information. For example, the second network function 1 establishes / releases / deletes the following processing entity and / or subchannel corresponding to at least one of the first channels: data encryption / decryption, integrity protection / verification processing entity, user plane data to the first channel mapping processing entity, RLC entity, logical channel. After receiving the first request information, the second network function 1 applies / releases / deletes the value of the first channel related parameter to the processing entity and / or subchannel related to the first channel, or determines and applies the processing entity and / or subchannel related parameters related to the first channel according to the value of the first channel related parameter. For example, the relevant parameters of the processing entity for data encryption / decryption, integrity protection / verification are determined and applied according to the value of the security parameter of the first channel. For another example, the relevant parameters of the RLC entity and the logical channel are determined and applied according to the value of the first channel related parameter. For another example, the mapping rule of the user plane data of the terminal to at least one first channel is applied to the processing entity for mapping the user plane data to the first channel.

[0398] After receiving the first request information, the second network function 1 stores / applies / modifies / releases / deletes the address information or identification information of the second channel peer.

[0399] The second network function 1 sends a first response message to the first network function. The first response message may also indicate at least one of the following: at least one first channel establishment / modification success or failure information, address information or identification information of the third network function in its corresponding second channel, at least one second channel establishment / modification success or failure information, an identification of the first channel context, an identification of the second channel context, an identification of the user plane data transmission channel context, and an associated identification.

[0400] 5. The fourth network function may also send a modification terminal context request message (fourth request message) to the first network function. The fourth network function indicates the terminal identifier, the updated or added second network function 1 identifier or address in the request message. The first network function modifies the terminal context and stores / applies the updated or added second network function 1 identifier or address. The first network function sends a modification terminal context response message (fourth response message) to the fourth network function, and the response message may indicate that the terminal context is successfully established or that the terminal context fails to be established.

[0401] 6. When it is no longer necessary to transmit the user plane data of the terminal, the fourth network function sends a release / deletion terminal context request message (fourth request message) to the first network function. The first network function sends a first request message to the second network function 1, and the first request message is used to indicate the release / deletion of the first channel and the release / deletion of the second channel. The second network function 1 releases / deletes the first channel and the second channel related to the terminal. The first network function releases / deletes the terminal context. The first network function sends a release / deletion terminal context response message (fourth response message) to the fourth network function.

[0402] Example 2: RAN includes a first network function, a second network function 1, a second network function 2, and a fourth network function.

[0403] The first network function 1 and the second network function 2 respectively carry different user plane data transmission functions. For example, the first network function 1 carries / supports / includes at least one of the following functions: RLC function, MAC function, part or all of the physical layer functions, and the function of carrying and processing sub-channels related to the first channel. The second network function 2 carries / supports / includes at least one of the following functions: data encryption / decryption, integrity protection / verification, and mapping of user plane data to the first channel. The channel through which the second network function 2 transmits the user plane data of the terminal between the second network function 1 and the terminal is the first channel. The second network function 2 and the network function in the core network used to transmit the user plane data of the terminal can directly exchange the user plane data of the terminal, and the channel between them for transmitting the user plane data of the terminal is the second channel.

[0404] The interaction between the first network function, the second network function 1, the second network function 2 and the fourth network function may be expressed in a reference point manner, such as Fig.13A As shown; it can also be based on a service-based representation, such as Fig. 13B As shown; you can also use two methods at the same time, such as Fig. 13C shown.

[0405] The process of controlling or managing the transmission of user plane data of the terminal through the RAN is as follows. The manner in which network functions interact with each other in the following process is not limited, for example, interaction can be performed through a point-to-point interface between network functions, or interaction can be performed through a service-based interface of each network function.

[0406] 1. Same as step 1 in Example 1.

[0407] 2. Same as step 2 in Example 1. Optionally, the fourth network function further indicates the identifier or address of the second network function 2 in the request information. Optionally, the first network function stores / applies the identifier or address of the second network function 2.
