[0252] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0253] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0254] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0255] To facilitate understanding of the solution proposed in this application, the relevant content will be introduced first.

[0256] (1) 5G system control plane

[0257] like Figure 1 As shown, the data sources required for transmission in the control plane of a wireless communication system consist of two parts: one is the Non-Access Stratum (NAS) signaling from the core network, and the other is the Radio Resource Control (RRC) signaling generated by the RAN itself. NAS signaling is transmitted within dedicated NAS-Messages. The bearer for control plane transmission is the Signalalling Radio Bearer (SRB), and the RRC signaling layer sits above the Packet Data Convergence Protocol (PDCP) layer. Figure 2 As shown, for the Centralized Unit (CU) and Distributed Unit (DU) separate architecture, the network-side RRC layer is in the CU.

[0258] Based on the RAN control plane service model, the radio interface requires a corresponding control plane message transmission scheme. However, currently, there is no feasible solution for how to transmit control plane messages between the radio access network side and the terminal.

[0259] To address the aforementioned technical problems, embodiments of this application provide a message transmission method, apparatus, device, and medium. The method and apparatus are based on the same concept. Since the methods and apparatus solve problems in similar ways, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0260] like Figure 3 The diagram shown is one of the flowcharts illustrating a message transmission method provided in an embodiment of this application. The method includes:

[0261] Step 301: The terminal sends a first radio resource control (RRC) message to a first object of the radio access network (RAN) device; wherein the first object includes at least one first functional module, and different first functional modules correspond to different RRC messages; or, the first object includes a second functional module, and the second functional module has a corresponding relationship with the signaling radio bearer (SRB) carrying the first RRC message.

[0262] RAN equipment includes, but is not limited to, base stations and relays. Here, the RAN equipment is modularized; see [link to documentation]. Figure 4 This diagram illustrates the modular radio interface control plane protocol stack for RAN devices. Specifically, it shows how the RAN device implements modularity at its RRC layer.

[0263] It should be noted that step 301 above includes two implementation methods.

[0264] Method 1: The terminal sends a first RRC message to at least one first functional module of the RAN device, and different first functional modules correspond to different RRC messages.

[0265] It should be understood that a RAN device contains one or more functional modules, and different functional modules correspond to different RRC messages. See also Figure 5 This explains that for RRC messages sent from the terminal to the RAN device, the RAN device's PDCP layer forwards the RRC message to all functional modules. These functional modules all parse the RRC message. Since different functional modules correspond to different RRC messages, only the functional module related to the specific RRC message processes it, thereby enabling the transmission of control plane messages between the RAN device's functional modules and the terminal.

[0266] Method 2: The terminal sends a first RRC message to the second functional module of the RAN device. The second functional module has a corresponding relationship with the SRB that carries the first RRC message.

[0267] It should be understood that each functional module's RRC message uses a separate SRB; see [link / reference]. Figure 6This explains that for RRC messages sent from a terminal to the RAN device, the RAN device's PDCP layer determines the corresponding functional module for RRC message transmission based on the SRB (i.e., logical channel) and delivers the RRC message to the corresponding functional module. Since each functional module's RRC message has a corresponding SRB, the RRC message sent from the terminal to the RAN device can be received and processed by the corresponding functional module through the SRB it carries, thereby enabling the transmission of control plane messages between the RAN device's functional modules and the terminal.

[0268] In some embodiments, the functional module includes one or more of the following:

[0269] Wireless bearer management function module; wherein, the wireless bearer management function module is used to manage and control the SRB of the wireless interface.

[0270] Wireless user management function module;

[0271] The wireless data management function module is used to manage and control data transmission and storage on the RAN side.

[0272] Wireless Network Open Function Module; the Wireless Network Open Function Module is used to manage the opening of RAN capabilities to external parties (core network, third parties, etc.).

[0273] Wireless network management function module;

[0274] The wireless resource management module is used to manage and coordinate wireless resources.

[0275] The target technology management module is used to manage target technologies, which are new technologies such as artificial intelligence (AI) technology and synesthetic technology.

[0276] As an optional embodiment, when the first object includes at least one first functional module, the first RRC message includes information for distinguishing the functional module; the information for distinguishing the functional module includes one or more of the following:

[0277] RRC message type;

[0278] Functional module identifier (ID);

[0279] Functional module index value;

[0280] Functional module name.

[0281] It should be understood that, for Method 1, the RRC message contains information used to distinguish functional modules. An example of the RRC message definition format is as follows:

[0282] ASN.1 format 1:

[0283]

[0284] --ASN1STOP

[0285] Among them, FunctionModule represents a functional module, RRC-MessageBody represents the RRC message body; radioBearManagement represents radio bearer management, dataManagement represents data management; aiManagement represents AI management; sensingManagement represents sensing management; capabilityExposure represents network open functions; and spare represents backup.

[0286] In practical applications, RRC format 1 can determine which functional module it is based on the specific value of functionModule.

[0287] ASN.1 format 2:

[0288]

[0289] Among them, FunctionIdentity represents the functional module ID; BIT STRING represents a bit string, which is a string of binary information used to represent the functional module ID.

[0290] In practical applications, RRC format 2 can determine the identifier ID corresponding to a functional module based on the specific value of functionIdentity.

[0291] ASN.1 format 3:

[0292]

[0293]

[0294] Among them, MessageType represents the message type (here referring to the type of RRC message); rrcSetupRequest represents an RRC establishment request; rrcResumeRequest represents an RRC recovery request; rrcReestablishmentRequest represents an RRC reconstruction request; rrcSystemInfoRequest represents an RRC system message request; rrcSetup represents RRC establishment; rrcResume represents RRC recovery; rrcRelease represents RRC release; rrcReestablishment represents RRC reconstruction; rrcSetupComplete represents RRC establishment completed; rrcResumeComplete represents RRC recovery completed; rrcReestablishmentComplete represents RRC reconstruction completed; securityModeCommand represents security mode command; securityModeComplete represents security mode establishment completed; ueCapabilityInformation represents terminal capability information; nasInformationTransfer represents non-access stratum message transmission; measurementReport represents measurement report; aiConfiguration represents AI configuration; aiConfigurationComplete represents AI configuration completed; sensingConfiguration represents sensing configuration; sensingConfigurationComplete represents sensing configuration completed.

[0295] In practical applications, RRC format 3 can determine which functional module it is based on the specific value of messageType.

[0296] Examples of RRC-MessageBody definitions in the above ASN.1 formats are shown below, listing only a few RRC messages:

[0297]

[0298]

[0299] Method 1 is adopted, namely: the terminal sends a first RRC message to at least one first functional module of the RAN device; when each first functional module of the RAN device receives the RRC message, since the first RRC message includes information for distinguishing functional modules, each first functional module parses the first RRC message, and only the first functional module related to the first RRC message processes the first RRC message. In this way, the transmission of control plane messages between the functional modules of the RAN device and the terminal can be realized.

[0300] Optionally, the header of the first RRC message includes the information used to distinguish functional modules. It should be noted that since the header of the RRC message includes information to distinguish functional modules, the RAN device only needs to parse the header of the RRC message, without having to parse the message body, thus improving the message processing efficiency of the RAN device.

[0301] In some embodiments, when the first object includes N first functional modules, the first RRC message includes parameters or functions of M first functional modules, where M and N are both positive integers greater than 1.

[0302] It should be understood that, for Method 1, different functional modules can correspond to different subsets of RRC parameters or RRC management functions, and a single RRC message can contain parameters or functions of multiple functional modules. In this case, the information included in the RRC message to distinguish functional modules can be recorded in list form; that is, the functional module ID, functional module index value, functional module name, etc., included in the RRC message can all be lists. In actual service transmission between the terminal and RAN equipment, using the parameters or functions of multiple functional modules contained in the RRC message can reduce the interaction between functional modules and save resources.

[0303] See Figure 7 The illustrated embodiment 1, using method 1, explains the specific implementation process of the message transmission method of this application from the perspective of inter-device interaction. Embodiment 1 corresponds to the establishment of AI and sensing service transmission between the terminal and the RAN equipment.

[0304] Step 1: The terminal initiates an RRC connection establishment request to the RAN device. The RRC connection establishment request is used to request the establishment of AI connection and sensor connection.

[0305] The RRC message header indicates that the destination functional module of the message is the Radio Bearer Management Module. Specifically, the RRC message format is as follows:

[0306] In RRC format 1, the functionModule value is radioBearManagement;

[0307] In RRC format 2, the functionIdentity value is the ID corresponding to the wireless bearer management module;

[0308] In RRC format 3, messageType is set to rrcSetupRequest.

[0309] In rrc-MessageBody, the value of rrc-MessageBody is RRCSetupRequest.

[0310] Specifically, after the PDCP layer on the RAN side receives the RRC connection establishment request message, it sends the message to all functional modules. Each functional module parses the RRC message and, based on the information contained in the RRC message header, only the radio bearer management module processes the message, while other functional modules discard the message.

[0311] Step 2: The wireless bearer management module sends an RRC connection establishment message to the terminal.

[0312] Step 3: The terminal sends an RRC connection establishment completion message to the RAN device. This message is also processed only by the Radio Bearer Management Module.

[0313] During the interaction in steps 1-3, the RAN device learns that the terminal requests to establish AI connection and sensor connection.

[0314] Step 4: The wireless bearer management module sends a security control command to the terminal to provide security information (encryption key, integrity key).

[0315] Step 5: The terminal sends a security module completion message to the RAN device.

[0316] Note: If the RAN device's security functions belong to other functional modules, steps 4 and 5 occur between those other functional modules and the terminal. It should be noted that the various functional modules of the RAN device can exchange information via service-based interfaces or internal interfaces.

[0317] Step 6: The wireless bearer management module triggers the AI ​​service management module to configure the terminal with AI, and the AI ​​service management module sends the AI ​​configuration information to the terminal.

[0318] Step 7: The terminal sends an AI configuration complete message to the AI ​​business management module.

[0319] Step 8: The wireless bearer management module triggers the sensing service management module to perform sensing configuration on the terminal, and sends the sensing configuration information to the terminal through the sensing service management module.

[0320] Step 9: The terminal sends a sensing configuration completion message to the sensing service management module.

[0321] Example 2 corresponds to the case where the RRC message contains parameters or functions of multiple functional modules.

[0322] The flowchart and steps of Embodiment 2 are the same as those of Embodiment 1. The difference is that in steps 1 and / or 3, the RRC message header indicates that the target functional module of the message includes the Radio Bearer Management Module, the AI ​​Service Management Module, and the Sensory Service Management Module. All three functional modules will process the message. The AI ​​Service Management Module and the Sensory Service Management Module can both be aware of the terminal's request message, which reduces the interaction between functional modules and saves resources.

[0323] In some embodiments, when the first object includes a second functional module, the SRB corresponding to the second functional module is pre-configured, protocol-defined, or network-configured.

[0324] Specifically, when the SRB corresponding to the second functional module is a network configuration, the SRB corresponding to the second functional module is configured by the radio bearer management module.

[0325] It should be understood that the Radio Bearer Management module is responsible for configuring the SRBs corresponding to each functional module. Through the message transmission method of this application, each functional module of the RAN device can achieve independent RRC message transmission.

[0326] Example 3, using method 2, illustrates the specific implementation process of the message transmission method of this application from the perspective of inter-device interaction. The flowchart of this example is the same as that of Example 1.

[0327] Step 1: The terminal initiates an RRC connection establishment request to the RAN device. This RRC connection establishment request message is sent using SRB0, and the reason for the establishment in the request message is AI communication.

[0328] Upon receiving the message, the PDCP layer of the RAN device sends the message to the Radio Bearer Management Module according to SRB0.

[0329] Step 2: The radio bearer management module sends an RRC connection establishment message to the terminal. In this RRC connection establishment message, SRB1 is configured as the control plane radio bearer between the terminal and the AI ​​service management module, and SRB2 is configured as the control plane radio bearer between the terminal and the sensing service management module.

[0330] Step 3: The terminal sends an RRC connection establishment completion message to the RAN device, also using SRB0.

[0331] Step 4: The wireless bearer management module uses SRB0 to send security control commands to the terminal to provide security information (encryption key, integrity key).

[0332] Step 5: The terminal UE uses SRB0 to send a safe mode completion message to the RAN device.

[0333] Note: If the RAN device-side security functions belong to other functional modules, and SRB2 is configured for the security function module in step 2, then steps 4 and 5 will use SRB2 for transmission. The functional modules on the RAN device side can exchange information via service-based interfaces or through internal interfaces.

[0334] Step 6: The AI ​​business management module configures the terminal for AI and sends the AI ​​configuration information to the terminal using SRB1.

[0335] Step 7: The terminal uses SRB1 to send an AI configuration complete message to the AI ​​business management module.

[0336] Step 8: The sensing service management module performs sensing configuration on the terminal and sends the sensing configuration information to the terminal using SRB2.

[0337] Step 9: The terminal uses SRB2 to send a sensing configuration completion message to the sensing service management module.

[0338] As an optional embodiment, step 301 above, in which the terminal sends a first Radio Resource Control (RRC) message to a first object of the Radio Access Network (RAN) device, includes:

[0339] The third functional module of the terminal sends a first RRC message to the first object of the RAN device.

[0340] Here, the terminal side is modularized; see [link / reference]. Figure 8 This is a schematic diagram of the modular wireless interface control plane protocol stack on the terminal side. The third functional module is responsible for service transmission between the terminal and the RAN equipment. Modular design on both the terminal and RAN equipment sides enables a more timely, flexible, and multi-dimensional wireless network.

[0341] Optionally, the third functional module includes one or more of the following:

[0342] Communication function module;

[0343] Artificial intelligence functional module;

[0344] Synesthesia module;

[0345] Target technology functional modules.

[0346] The message transmission method of this application embodiment involves a terminal sending a first RRC message to a first object of a radio access network (RAN) device. The first object includes at least one first functional module, with different first functional modules corresponding to different RRC messages. Since different functional modules correspond to different RRC messages, the first RRC message sent by the terminal to the RAN device can be received and processed by the corresponding functional module, thereby enabling the transmission of control plane messages between the functional modules of the RAN device and the terminal. Alternatively, the first object includes a second functional module, and the second functional module has a corresponding SRB carrying the first RRC message. In this way, since each functional module's RRC message has a corresponding SRB, the first RRC message sent by the terminal to the RAN device can be received and processed by the corresponding functional module through the SRB it carries, thereby also enabling the transmission of control plane messages between the functional modules of the RAN device and the terminal.

[0347] like Figure 9 The diagram shown is a second flowchart illustrating a message transmission method provided in this application. The method includes:

[0348] Step 901: The first object of the radio access network (RAN) device receives a first radio resource control (RRC) message sent by the terminal; wherein the first object includes at least one first functional module, and different functional modules correspond to different RRC messages; or, the first object includes a second functional module, and the second functional module has a corresponding relationship with the signaling radio bearer (SRB) carrying the first RRC message.

[0349] The methods on the RAN equipment side correspond to those on the terminal side. The RAN equipment includes, but is not limited to, base stations and relays. Here, the RAN equipment side is modular.

[0350] It should be noted that step 901 above includes two implementation methods.

[0351] Method 1: At least one first functional module of the RAN device receives the first RRC message sent by the terminal, and different first functional modules correspond to different RRC messages.

[0352] It should be understood that a RAN device contains one or more functional modules, and different functional modules correspond to different RRC messages. See also Figure 5 This explains that for RRC messages sent from the terminal to the RAN device, the RAN device's PDCP layer forwards the RRC message to all functional modules. These functional modules all parse the RRC message. Since different functional modules correspond to different RRC messages, only the functional module related to the specific RRC message processes it, thereby enabling the transmission of control plane messages between the RAN device's functional modules and the terminal.

[0353] Method 2: The second functional module of the RAN device receives the first RRC message sent by the terminal. The second functional module has a corresponding relationship with the SRB that carries the first RRC message.

[0354] It should be understood that each functional module's RRC message uses a separate SRB; see [link / reference]. Figure 6 This explains that for RRC messages sent from a terminal to the RAN device, the RAN device's PDCP layer determines the corresponding functional module for RRC message transmission based on the SRB (i.e., logical channel) and delivers the RRC message to the corresponding functional module. Since each functional module's RRC message has a corresponding SRB, the RRC message sent from the terminal to the RAN device can be received and processed by the corresponding functional module through the SRB it carries, thereby enabling the transmission of control plane messages between the RAN device's functional modules and the terminal.

[0355] In some embodiments, the functional module includes one or more of the following:

[0356] Wireless bearer management function module;

[0357] Wireless user management function module;

[0358] Wireless data management function module;

[0359] Wireless network open function module;

[0360] Wireless network management function module;

[0361] Wireless resource management function module;

[0362] Target technology management function module.

[0363] As an optional embodiment, the method of this application further includes:

[0364] The target functional module of the RAN device processes the first RRC message and generates a second RRC message; wherein, when the first object includes at least one first functional module, the target functional module corresponds to the first RRC message, and the target functional module is one of the at least one first functional module; when the first object includes a second functional module, the target functional module is the second functional module.

[0365] Here, when the first object includes at least one first functional module, the RAN device processes the first RRC message (target functional module) corresponding to the first RRC message to generate a second RRC message. That is, the RAN device's PDCP layer sends the first RRC message to all first functional modules. All these first functional modules parse the first RRC message, and only the functional module corresponding to the first RRC message processes it, thereby enabling the transmission of control plane messages between the RAN device's functional modules and the terminal.

[0366] When the first object includes a second functional module, the second functional module of the RAN device processes the first RRC message and generates a second RRC message. It should be understood that each functional module's RRC message uses a separate SRB. For the first RRC message sent by the terminal to the RAN device, the RAN device's PDCP layer determines the corresponding second functional module based on the SRB (i.e., based on the logical channel) and delivers the RRC message to the corresponding second functional module. This also enables the transmission of control plane messages between the RAN device's functional modules and the terminal.

[0367] Furthermore, when the first object includes at least one first functional module, the method of this application further includes:

[0368] Other functional modules in the RAN device besides the target functional module discard the first RRC message.

[0369] Here, each of the first functional modules of the RAN device parses the first RRC message. Only the target functional module related to the first RRC message processes the first RRC message, while other functional modules discard the first RRC message.

[0370] In some embodiments, where the first object includes at least one first functional module, the first RRC message includes information for distinguishing the functional module; the information for distinguishing the functional module includes one or more of the following:

[0371] RRC message type;

[0372] Functional module identifier;

[0373] Functional module index value;

[0374] Functional module name.

[0375] Optionally, the header of the first RRC message includes the information used to distinguish functional modules.

[0376] In some embodiments, when the first object includes N first functional modules, the first RRC message includes parameters or functions of M first functional modules, where M and N are both positive integers greater than 1.

[0377] It should be understood that, for Method 1, different functional modules can correspond to different subsets of RRC parameters or RRC management functions, and a single RRC message can contain parameters or functions of multiple functional modules. In this case, the information included in the RRC message to distinguish functional modules can be recorded in list form; that is, the functional module ID, functional module index value, functional module name, etc., included in the RRC message can all be lists. In actual service transmission between the terminal and RAN equipment, using the parameters or functions of multiple functional modules contained in the RRC message can reduce the interaction between functional modules and save resources.

[0378] In some embodiments, when the first object includes a second functional module, the SRB corresponding to the second functional module is pre-configured, protocol-defined, or network-configured.

[0379] Specifically, when the SRB corresponding to the second functional module is a network configuration, the SRB corresponding to the second functional module is configured by the radio bearer management module.

[0380] It should be understood that the Radio Bearer Management module is responsible for configuring the SRBs corresponding to each functional module. Through the message transmission method of this application, each functional module of the RAN device can achieve independent RRC message transmission.

[0381] As an optional embodiment, in step 901 above, the first object receiving terminal of the radio access network (RAN) device sends a first radio resource control (RRC) message, including:

[0382] The first object of the RAN device receives the first RRC message sent by the third functional module of the terminal.

[0383] Here, the terminal side is modularized, with the third functional module being the service transmission-related module when the terminal transmits services to the RAN equipment. Modularization on both the terminal and RAN equipment sides enables a more timely, flexible, and multi-dimensional wireless network.

[0384] Optionally, the third functional module includes one or more of the following:

[0385] Communication function module;

[0386] Artificial intelligence functional module;

[0387] Synesthesia module;

[0388] Target technology functional modules.

[0389] It should be understood that if the terminal and the RAN equipment are transmitting AI services, then the third functional module is the AI ​​function module, and it transmits AI service data with the AI ​​module on the RAN equipment side; if the terminal and the RAN equipment are transmitting sensing services, then the third functional module is the sensing function module, and it transmits sensing service data with the sensing function module on the RAN equipment side.

[0390] The message transmission method of this application embodiment involves a first object of a Radio Access Network (RAN) device receiving a first Radio Resource Control (RRC) message sent by a terminal. The first object includes at least one first functional module, with different functional modules corresponding to different RRC messages. Thus, since different functional modules correspond to different RRC messages, the first RRC message sent by the terminal can be processed by the corresponding functional module, thereby enabling the transmission of control plane messages between the RAN device's functional modules and the terminal. Alternatively, the first object may include a second functional module, which corresponds to a Signaling Radio Bearer (SRB) carrying the first RRC message. In this case, since each functional module's RRC message has a corresponding SRB, the SRB corresponding to the first RRC message sent by the terminal can be processed by the corresponding functional module, also enabling the transmission of control plane messages between the RAN device's functional modules and the terminal.

[0391] like Figure 10 The diagram shown is a third flowchart illustrating the message transmission method provided in this application embodiment.

[0392] The method includes:

[0393] Step 1001: The terminal receives a third Radio Resource Control (RRC) message sent by the fourth functional module of the Radio Access Network (RAN) device.

[0394] Figure 3 The embodiment shown in this application corresponds to the scenario where the terminal sends an RRC message and the RAN device receives the RRC message; here Figure 10 The illustrated embodiment corresponds to the scenario where the RAN device sends RRC messages, and the terminal also sends RRC messages. That is, both the terminal and the RAN device can complete message sending and receiving. Furthermore, Figure 3 In the illustrated embodiment, the terminal sends an RRC message, along with... Figure 10 In the illustrated embodiment, the terminals receive RRC messages, which may or may not be related to each other, depending on the service being transmitted. No specific limitation is made here.

[0395] The RAN equipment includes, but is not limited to, base stations and relays. Here, the RAN equipment is modular. For explanations and descriptions related to the method in this embodiment, please refer to... Figure 3 The method shown will not be elaborated here.

[0396] In some embodiments, the functional module includes one or more of the following:

[0397] Wireless bearer management function module;

[0398] Wireless user management function module;

[0399] Wireless data management function module;

[0400] Wireless network open function module;

[0401] Wireless network management function module;

[0402] Wireless resource management function module;

[0403] Target technology management function module.

[0404] As an optional embodiment, the third RRC message includes information for distinguishing functional modules; the information for distinguishing functional modules includes one or more of the following:

[0405] RRC message type;

[0406] Functional module identifier;

[0407] Functional module index value;

[0408] Functional module name.

[0409] It should be noted that the terminal can determine which functional module on the RAN device side sent the third RRC message based on the information contained in the third RRC message used to distinguish functional modules, and further perform service-related processing on the third RRC message.

[0410] Optionally, the header of the third RRC message includes the information used to distinguish the functional modules.

[0411] It should be noted that the message header of the RRC message contains information used to distinguish functional modules. This means that the terminal only needs to parse the message header of the RRC message, without having to parse the message body, which can improve the message processing efficiency of the terminal.

[0412] In some embodiments, the fourth functional module corresponds to the signaling radio bearer (SRB) carrying the third RRC message.

[0413] It should be understood that each functional module uses a separate SRB for its RRC message. The terminal side can determine that the corresponding functional module is the fourth functional module by using the SRB that carries the third RRC message. Furthermore, the third RRC message is processed in a business-related manner.

[0414] Optionally, the SRB corresponding to the fourth functional module is pre-configured, protocol-defined, or network-configured.

[0415] Specifically, when the SRB corresponding to the fourth functional module is a network configuration, the SRB corresponding to the fourth functional module is configured by the radio bearer management module.

[0416] It should be understood that the Radio Bearer Management module is responsible for configuring the SRBs corresponding to each functional module. Through the message transmission method of this application, each functional module of the RAN device can achieve independent RRC message transmission.

[0417] As an optional embodiment, in step 1001 above, the terminal receives a third Radio Resource Control (RRC) message sent by the fourth functional module of the Radio Access Network (RAN) device, including:

[0418] The fifth functional module of the terminal receives the third RRC message sent by the fourth functional module of the RAN device.

[0419] Here, the terminal side is modularized, with the fifth functional module being the service transmission-related module when the terminal transmits services to the RAN equipment. Modularization on both the terminal and RAN equipment sides enables a more timely, flexible, and multi-dimensional wireless network.

[0420] Optionally, the fifth functional module includes one or more of the following:

[0421] Communication function module;

[0422] Artificial intelligence functional module;

[0423] Synesthesia module;

[0424] Target technology functional modules.

[0425] The message transmission method of this application embodiment involves a terminal receiving a third RRC message sent by a fourth functional module of a radio access network (RAN) device. The fourth functional module is one of multiple functional modules in the RAN device, with different functional modules corresponding to different RRC messages. Alternatively, the fourth functional module may correspond to an SRB carrying the third RRC message. This allows the terminal to determine the corresponding functional module and process the RRC message, thereby enabling the transmission of control plane messages between the functional modules of the RAN device and the terminal.

[0426] like Figure 11 The diagram shown is a fourth flowchart illustrating the message transmission method provided in this application embodiment.

[0427] The method includes:

[0428] Step 1101: The fourth functional module of the radio access network (RAN) device sends a third radio resource control (RRC) message to the terminal.

[0429] Figure 11 The method shown on the RAN device side is similar to Figure 10 The method shown corresponds to the terminal side.

[0430] Optionally, the fourth functional module is one of multiple functional modules in the RAN device, with different functional modules corresponding to different RRC messages. Alternatively, the fourth functional module may correspond to an SRB carrying a third RRC message. This allows the terminal to determine the corresponding functional module and process the RRC message, thus enabling the transmission of control plane messages between the functional modules of the RAN device and the terminal.

[0431] In some embodiments, the functional module includes one or more of the following:

[0432] Wireless bearer management function module;

[0433] Wireless user management function module;

[0434] Wireless data management function module;

[0435] Wireless network open function module;

[0436] Wireless network management function module;

[0437] Wireless resource management function module;

[0438] Target technology management function module.

[0439] As an optional embodiment, the third RRC message includes information for distinguishing functional modules; the information for distinguishing functional modules includes one or more of the following:

[0440] RRC message type;

[0441] Functional module identifier;

[0442] Functional module index value;

[0443] Functional module name.

[0444] It should be noted that this allows the terminal to determine which functional module on the RAN device side sent the third RRC message based on the information contained in the third RRC message used to distinguish functional modules, and further perform service-related processing on the third RRC message.

[0445] Optionally, the header of the third RRC message includes the information used to distinguish functional modules.

[0446] It should be noted that the message header of the RRC message contains information used to distinguish functional modules. This allows the terminal to parse only the message header of the RRC message without having to parse the message body, thus improving the terminal's message processing efficiency.

[0447] In some embodiments, the fourth functional module corresponds to the signaling radio bearer (SRB) carrying the third RRC message.

[0448] It should be understood that each functional module uses a separate SRB for its RRC message, which allows the terminal to determine that the corresponding functional module is the fourth functional module by using the SRB that carries the third RRC message. Furthermore, the terminal can perform business-related processing on the third RRC message.

[0449] Optionally, the SRB corresponding to the fourth functional module is pre-configured, protocol-defined, or network-configured.

[0450] Specifically, when the SRB corresponding to the fourth functional module is a network configuration, the SRB corresponding to the fourth functional module is configured by the radio bearer management module.

[0451] It should be understood that the Radio Bearer Management module is responsible for configuring the SRBs corresponding to each functional module. Through the message transmission method of this application, each functional module of the RAN device can achieve independent RRC message transmission.

[0452] As an optional embodiment, in step 1101 above, the fourth functional module of the radio access network (RAN) device sends a third radio resource control (RRC) message to the terminal, including:

[0453] The fourth functional module of the RAN device sends a third RRC message to the fifth functional module of the terminal.

[0454] Here, the terminal side is modularized, with the fifth functional module being the service transmission-related module when the terminal transmits services to the RAN equipment. Modularization on both the terminal and RAN equipment sides enables a more timely, flexible, and multi-dimensional wireless network.

[0455] Optionally, the fifth functional module includes one or more of the following:

[0456] Communication function module;

[0457] Artificial intelligence functional module;

[0458] Synesthesia module;

[0459] Target technology functional modules.
