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.

[0235] The following is an introduction to the relevant technologies involved in this application:

[0236] 1. NRF equipment

[0237] See also Figure 1 , a non-roaming 5G system architecture diagram is given. The architecture involves the control plane network slice selection function (Network Slice Selection Function, NSSF) equipment, network exposure function (Network Exposure Function. NEF) equipment, policy and control function (Policy Control Function, PCF) equipment, unified data management (Unified Data Management, PCF) equipment, application function (Unified Data Management, AF) equipment, NRF equipment, as well as authentication service function (Authentication Server Function, ASF) equipment, access and mobility management function (Authentication Server Function, AMF) equipment, session management function (Session Management Function, SMF) equipment. Of course, the control plane can also involve other core network equipment, etc., which will not be repeated here.

[0238] Access network equipment (such as Radio Access Network (RAN)) and AMF equipment can communicate based on the N2 interface. Terminal equipment or User Equipment (UE) communicates with AMF equipment through access network equipment. User Plane Function (UPF) equipment and SMF equipment can communicate based on the N4 interface, SMF equipment and access network equipment can communicate based on the N3 interface, and SMF equipment and data network (DN) equipment can communicate based on the N6 interface.

[0239] Among them, the NRF device supports the service discovery function, that is, receiving the NF discovery request from the NF instance or the Service Communication Proxy (SCP), and providing the information of the discovered NF instance (discovered) to the NF instance or SCP; maintaining the NF profiles of the available NF instances and their supported services.

[0240] The NF services provided by NRF include but are not limited to the following:

[0241] Network Function Registration (Nnrf_NFManagement_NFRegister): Register the consumer NF in NRF by providing the NF profile of the consumer NF to NRF, and NRF marks the consumer NF as available. For example, the registration may carry the NF type, NF instance identifier (ID), the name of the supported NF service and the Public Land Mobile Network Identifier (PLMN ID), etc.

[0242] Network Function Update (Nnrf_NFManagement_NFUpdate): Provides updated NF profile of NF consumer to NRF. For example, the update can carry NF instance ID. Optionally, if the complete NF profile is replaced, the update should carry the complete NF profile. If part of the NF profile is updated, the update should provide the NF profile elements that need to be updated.

[0243] Network function deregistration or deregistration (Nnrf_NFManagement_NFDeregister): Notify NF consumer that it is unavailable to NRF. For example, the NF instance ID can be carried when deregistering or deregistering.

[0244] 2. Network capability opening

[0245] With the development of artificial intelligence technology, network intelligence has become an inevitable trend in the future development of networks, especially in 6G networks, where artificial intelligence technology will be integrated into the network architecture to achieve endogenous intelligence. Future mobile networks must support ubiquitous applications, especially extreme applications, which require the integration of networks and services. Networks need to be more agile, intelligent, and open, provide more channels and public services, realize mutual perception and coordination between networks and applications, and optimize the experience of users and applications and maximize network value.

[0246] Network capability opening provides an open environment for traditional network opening and new capabilities such as intelligence, computing power, and synaesthesia. Future mobile networks will provide more flexible means of network capability opening, such as local opening, user plane opening, combined or nested opening, and multi-party collaborative opening; capability opening will provide a shared environment for multi-party supply, with appropriate incentive mechanisms, and realize the release and on-demand calling of capabilities by providing a flexible and dynamic registration mechanism; capability opening will provide services with friendly service-oriented interfaces, and benefit from the full protection of the network's inherent intelligence and inherent security.

[0247] 3. RAN Service-Oriented

[0248] In order to meet the requirements of 5G diversified services for network agility, flexibility and scalability, the transformation of networks to virtualization and cloudification is an inevitable trend. Cloud Radio Access Network (Cloud RAN) has also been widely favored by global operators. It includes two core features: universal hardware platform and cloud native technology. 6G wireless network will not only be Cloud RAN, but also service-oriented RAN.

[0249] In order to meet the needs of rapid launch of diversified services, the 5G core network uses service-oriented architecture as the network infrastructure and makes in-depth optimization based on the separation of control plane and user plane. The control plane of the 5G core network is modularly decomposed into different network functions. The decoupled network functions can be expanded, evolved and deployed on demand independently. Each network function has multiple network function services, which can realize on-demand customization of core network functions and flexibly support different business scenarios and needs.

[0250] The next generation of wireless access networks needs to reconstruct wireless networks into service-oriented RANs with finer granularity from the perspective of service capabilities. The definition of service-oriented interfaces between RAN services and core network services will bring new interaction methods to end-to-end network processes, while reducing the impact of cross-domain new functions on existing services; the definition of service-oriented interfaces between RAN services and third-party services will enable more timely and multi-dimensional wireless network capability opening; the integrated orchestration and management of RAN services and core network (CN) services will reduce the complexity of network operation and maintenance management and improve the network's adaptability to new services.

[0251] Taking into account the maturity of the industry, the maturity of the technology and other aspects, the development of service-oriented RAN may include the following five levels: service-oriented control plane interface to achieve direct cross-domain functional access; service-oriented RAN control plane to help optimize the end-to-end process; service-oriented RAN user plane to create the ultimate cross-layer transmission experience; service-oriented RAN upgrade to deeply integrate data technology (DT), operational technology (OT), Internet technology (IT) and communication technology (CT), that is, deeply integrate the new elements of DOICT; stimulate UE service capabilities to achieve end-to-network service capability sharing.

[0252] 4. UPF service

[0253] The 5G core network interacts through a service-based interface (SBI). However, 5G service-based is only for the control plane. For user plane devices (such as UPF), there is no service-based interface for other core network devices to use. User plane network function devices need to be further service-based to provide services to the outside world.

[0254] The UPF service-oriented interface is described as follows: In the 5G core network (5GC), UPF provides services to NEF and AF based on the Nupf service interface. UPF supports the following functions: Notification of service quality (QoS) monitoring information.

[0255] The content of UPF service is shown in Table 1:

[0256] Table 1

[0257]

[0258] The embodiment of the present application provides an information processing method, a core network device, an access network device and a terminal device, which solves the problem that the current core network device cannot meet the enhanced management of network capabilities. Among them, the method and the core network device (or access network device or terminal device) are based on the same application concept. Since the principles of solving the problem by the method and the core network device (or access network device or terminal device) are similar, the implementation of the method and the core network device (or access network device or terminal device) can refer to each other, and the repeated parts will not be repeated.

[0259] like Figure 2 As shown, an embodiment of the present invention provides an information processing method, comprising the following steps:

[0260] Step 21: The first core network device receives network capability related information of the first device.

[0261] Among them, the first device includes at least one of the following: terminal equipment, access network equipment, and second core network equipment.

[0262] That is, the network capability-related information of the first device includes at least one of the following:

[0263] Information related to the network capabilities of the terminal device;

[0264] Information related to the network capabilities of access network equipment;

[0265] Information related to the network capabilities of the second core network device.

[0266] Optionally, the first core network device may be an NRF device.

[0267] For example: the network capability-related information of the terminal device can be provided by the terminal device to the access network device (for example, the access network device can be the service RAN device of the terminal device), and provided by the first access network device to the first core network device. Alternatively, the network capability-related information of the terminal device can be provided by the terminal device to the access network device, and provided by the access network device to the second core network device (for example, the second core network device can be an AMF device or an SMF device or other core network device, etc.), and provided by the second core network device to the first core network device, etc.

[0268] For example, the network capability-related information of the access network device can be provided by the access network device to the first core network device. Alternatively, the network capability-related information of the access network device can be provided by the access network device to the second core network device (for example, the second core network device can be an AMF device or an SMF device or other core network device, etc.), and provided by the second core network device to the first core network device, etc.

[0269] For example: the network capability-related information of the second core network device can be provided by the second core network device to the first core network device. Optionally, the second core network device is a service consumer NF device or UPF device or other core network device, etc., and the service consumer NF device or UPF device can provide its own network capability-related information to the first core network device (such as an NRF device or other core network device, etc.). Or the second core network device is the NRF device of the first distribution node, and the NRF device of the first distribution node can provide its own network capability-related information to the first core network device (such as the NRF device of the centralized node or the NRF device of the second distribution node, etc.).

[0270] Step 22: The first core network device performs network function management according to the network capability related information of the first device.

[0271] Optionally, the network function management includes but is not limited to at least one of the following: network function registration, network function update, network function deregistration, etc.

[0272] For example: when the network capability related information of the first device includes the network capability related information of the terminal device, the first core network device can perform the registration of the terminal device, update the network capability related information of the terminal device, or perform the deregistration of the terminal device. Alternatively, when the network capability related information of the first device includes the network capability related information of the access network device, the first core network device can perform the registration of the access network device, update the network capability related information of the access network device, or perform the deregistration of the access network device. Alternatively, when the network capability related information of the first device includes the network capability related information of the second core network device, the first core network device can perform the registration of the second core network device, update the network capability related information of the second core network device, or perform the deregistration of the second core network device.

[0273] In the above solution, the first core network device receives the network capability related information of the first device, and the first device includes at least one of the following: terminal device, access network device, and second core network device. In this way, the first core network device can implement network function management of at least one of the terminal device, access network device, and second core network device based on the network capability related information of the first device, that is, the network function of the first core network device is enhanced, which can solve the problem that the network capability enhancement management of the core network device cannot be met at present.

[0274] Optionally, the network capability-related information of the first device includes at least one of the following:

[0275] The network capabilities supported by the first device; for example: the network capabilities include but are not limited to at least one of the following: computing power capabilities, AI capabilities, security capabilities, etc., and the embodiments of the present application are not limited to this.

[0277] second indication information, used to indicate whether the network capability supported by the first device is restricted from being called;

[0278] The third indication information is used to indicate that the network capabilities supported by the first device limit the type of device being called.

[0279] Optionally, the network capability related information of the first device may also include: fourth indication information, used to indicate the device type supported for network capability exposure, etc. Of course, the network capability related information of the embodiment of the present application is not limited to including other network capability related information, etc., and the embodiment of the present application is not limited thereto.

[0280] For example, information related to the network capabilities of a terminal device includes at least one of the following:

[0281] Network capabilities supported by the terminal device;

[0282] The first indication information is used to indicate whether the network capabilities supported by the terminal device are open; for example: whether all network capabilities supported by the terminal device are open, or which network capabilities supported by the terminal device are open, etc. The embodiments of the present application are not limited to this.

[0283] The second indication information is used to indicate whether the network capabilities supported by the terminal device are restricted from being called; for example: whether all network capabilities supported by the terminal device are restricted from being called, or which network capabilities supported by the terminal device are restricted from being called, etc. The embodiments of the present application are not limited to this.

[0284] The third indication information is used to indicate that the network capabilities supported by the terminal device limit the type of device being called; for example: the network capabilities supported by the terminal device limit which device type or types of devices (such as other terminal devices, access network devices or core network devices, etc.) can be called, or it can be understood that the network capabilities supported by the terminal device do not allow which device type or types of devices to be called, etc., that is, the network capabilities of the terminal device can be called by all other devices, and can also limit the types of other devices that call its network capabilities, etc. The embodiments of the present application are not limited to this.

[0285] For example, information related to the network capabilities of access network equipment includes at least one of the following:

[0286] Network capabilities supported by access network equipment;

[0287] The indication information is used to indicate whether the network capabilities supported by the access network device are open; for example: whether all network capabilities supported by the access network device are open, or which network capabilities supported by the access network device are open, etc. The embodiments of the present application are not limited to this.

[0288] The second indication information is used to indicate whether the network capabilities supported by the access network device are restricted from being called; for example: whether all network capabilities supported by the first access network device are restricted from being called, or which network capabilities supported by the first access network device are restricted from being called, etc. The embodiments of the present application are not limited to this.

[0289] The third indication information is used to indicate that the network capabilities supported by the access network device limit the type of device being called; for example: the network capabilities supported by the access network device limit which device type or types of devices (such as terminal devices, other access network devices or core network devices, etc.) can be called, or it can be understood that the network capabilities supported by the access network device do not allow which device type or types of devices to be called, etc., that is, the network capabilities of the access network device can be called by all other devices, and can also limit the types of other devices that call its network capabilities, etc. The embodiments of the present application are not limited to this.

[0290] For example, the network capability-related information for the second core network device includes at least one of the following:

[0292] The first indication information is used to indicate whether the network capabilities supported by the second core network device are open; for example: whether all network capabilities supported by the second core network device are open, or which network capabilities supported by the second core network device are open, etc. The embodiments of the present application are not limited to this.

[0293] The second indication information is used to indicate whether the network capabilities supported by the second core network device are restricted from being called; for example: whether all network capabilities supported by the second core network device are restricted from being called, or which network capabilities supported by the second core network device are restricted from being called, etc. The embodiments of the present application are not limited to this.

[0294] The third indication information is used to indicate that the network capabilities supported by the second core network device limit the type of device being called; for example: the network capabilities supported by the second core network device limit which device type or types of devices (such as terminal devices, access network devices or other core network devices, etc.) can be called, or it can be understood that the network capabilities supported by the second core network device do not allow which device type or types of devices to be called, etc., that is, the network capabilities of the second core network device can be called by all other devices, and can also limit the types of other devices that call its network capabilities, etc. The embodiments of the present application are not limited to this.

[0295] Optionally, the first core network device receives information related to network capability of the first device, including:

[0296] The first core network device receives at least one of the following information sent by the access network device: information related to the network capability of the terminal device and information related to the network capability of the access network device;

[0297] and / or,

[0298] The first core network device receives at least one of the following information sent by the second core network device: information related to the network capabilities of the terminal device, information related to the network capabilities of the access network device, and information related to the network capabilities of the second core network device.

[0299] In this embodiment, for the access network device, it can provide the first core network device with information related to its own network capabilities, and can also provide the first core network device with information related to the network capabilities of the corresponding terminal device, etc. For the second core network device, it can provide the first core network device with information related to its own network capabilities, and can also provide the first core network device with information related to the network capabilities of the corresponding access network device, and can also provide the first core network device with information related to the network capabilities of the terminal device, or can also provide the first core network device with information related to the network capabilities of other core network devices (for example, the SMF device can provide the first core network device with information related to the network capabilities of the UPF device, etc.), and the embodiments of the present application are not limited to this.

[0300] Optionally, the terminal device, or the access network device, or the second core network device may register its own network capabilities with the first core network device. For example, the first core network device receives information related to the network capabilities of the first device, including:

[0301] The first core network device receives a registration message; wherein the registration message carries network capability related information of the first device;

[0302] The first core network device performs network function management according to the network capability related information of the first device, including:

[0303] The first core network device stores the network capability-related information of the first device according to the registration message, and determines that the first device is in an available state.

[0304] That is, the first core network device performs registration management on the first device according to the registration message, for example, performing registration management on at least one of the terminal device, access network device, and second core network device included in the first device.

[0305] For example: the first core network device receives a registration message sent by the second core network device, and the registration message carries at least one of the following information: information related to the network capabilities of the terminal device, information related to the network capabilities of the access network device, and information related to the network capabilities of the second core network device. Optionally, the first core network device is a network storage functional device; and / or, the second core network device includes at least one of the following: a service consumer network functional device, a user plane functional device. Or optionally, the first core network device is a network storage functional device of a first distributed node; and / or, the second core network device includes at least one of the following: a network storage functional device of a second distributed node, a network storage functional device of a centralized node.

[0306] The following describes the process of registering the network capability of the second core network device in conjunction with an embodiment:

[0307] Embodiment 1: The service consumer NF device (i.e., the second core network element) registers the network capability with the NRF device (i.e., the first core network device), such as Figure 3 As shown, the following steps are included:

[0308] Step 31: The service consumer NF device sends a registration request message (such as Nnrf_NFManagement_NFRegister) to the NRF device to notify the NRF device of the NF configuration file of the service consumer NF device when the service consumer NF device starts working for the first time.

[0309] Optionally, the NF configuration file includes but is not limited to at least one of the following:

[0310] NF type;

[0311] NF instance ID;

[0312] The name of the NF service supported;

[0313] PLMN ID;

[0314] Information related to the network capabilities of the first device, such as information related to the network capabilities (such as computing power, AI capabilities, security capabilities, etc.) possessed by the service consumer NF device itself, or information related to the network capabilities of the access network device itself transmitted by the access network device through the service consumer NF device, or information related to the network capabilities of the terminal device itself, etc.

[0315] Step 32: The NRF device stores the NF configuration file of the service consumer NF device and marks the service consumer NF device as available.

[0316] Step 33: The NRF device sends a registration response message (such as Nnrf_NFManagement_NFRegister) to the service consumer NF device to notify the service consumer NF device to accept the NF registration.

[0317] Embodiment 2: The UPF device (i.e., the second core network element) registers network capabilities with the NRF device (i.e., the first core network device);

[0318] Specifically, when the UPF device needs to register its own network capabilities with the NRF device, other core network devices (such as SMF devices, etc.) that are known to have the network capabilities of the UPF device can register services with the NRF device instead of the UPF device, such as the SMF device sending the configuration file of the UPF device to the NRF device. For example, the configuration file includes information related to the network capabilities of the UPF device.

[0319] Alternatively, when the UPF device needs to register its own network capabilities with the NRF device, the UPF device can directly register the service to the NRF device as an NF device (such as in a service-oriented scenario). The configuration file during registration includes information related to the network capabilities of the UPF device, etc.

[0320] Embodiment 3: The NRF device of the first distribution node (i.e., the second core network device) registers network capabilities with the NRF device of the second distribution node (i.e., the NRF devices of other branch nodes except the first distribution node, i.e., the first core network device) or the NRF device of the centralized node (i.e., the first core network device);

[0321] Specifically, in a distributed network scenario, the NRF device of a distribution node can register services as an NF device to the NRF devices of other distribution nodes or centralized nodes. For example, the NRF device of a distribution node sends a configuration file to the NRF devices of other distribution nodes or centralized nodes, and the configuration file includes network capability-related information of the NRF device of the distribution node.

[0322] For example, the first core network device receives a registration message sent by an access network device, and the registration message carries at least one of the following information: network capability-related information of the terminal device and network capability-related information of the access network device. Optionally, the first core network device is a network storage function device.

[0323] The following describes the process of registering network capabilities of an access network device in conjunction with an embodiment:

[0324] Embodiment 4: The RAN device registers network capabilities with the NRF device (ie, the first core network device);

[0325] Specifically, if the RAN device needs to register its own network capabilities with the NRF device, other core network devices (such as AMF devices, SMF devices, etc.) that know the network capabilities of the RAN device itself can register services with the NRF device instead of the RAN device, such as sending the configuration file of the RAN device to the NRF device by the AMF device, SMF device, etc. For example, the configuration file includes information related to the network capabilities of the RAN device.

[0326] Alternatively, if the RAN device needs to register its own network capabilities with the NRF device, the RAN can directly register the service with the NRF device as an NF device (such as in a service-oriented scenario). The configuration file during registration includes information related to the network capabilities of the RAN device, etc.

[0327] Embodiment 5: The UE registers network capabilities with the NRF device (ie, the first core network device);

[0328] Specifically, in a user-centric network scenario, the UE's own capabilities are gradually strengthened. For example, when the UE needs to register its own network capabilities with the NRF device, other core network devices (such as AMF devices, SMF devices, etc.) that know the network capabilities of the UE itself can register the service with the NRF device on behalf of the UE, such as sending the UE's configuration file to the NRF device by the AMF device, SMF device, etc. For example, the configuration file includes information related to the UE's network capabilities.

[0329] Alternatively, when the UE needs to register its own network capabilities with the NRF device, it registers for services with the NRF device through the RAN device (such as in a service-oriented scenario), and the configuration file during registration includes information related to the network capabilities of the UE.

[0330] Optionally, the terminal device, or the access network device, or the second core network device may update its own network capabilities to the first core network device. For example, the first core network device receives information related to the network capabilities of the first device, including:

[0331] The first core network device receives an update message; wherein the update message carries network capability related information of the first device;

[0332] The first core network device performs network function management according to the network capability related information of the first device, including:

[0333] The first core network device updates the network capability related information of the first device according to the update message.

[0334] That is, the first core network device performs network capability update management on the first device, such as performing network capability update management on at least one of the terminal device, the first access network device, and the second core network device included in the first device.

[0335] It should be noted that the update message carries information related to the network capabilities of the first device, that is, information related to the network capabilities updated by the first device, including but not limited to at least one of the following: information related to the network capabilities updated by the terminal device, information related to the network capabilities updated by the access network device, information related to the network capabilities updated by the second core network device, etc.

[0336] Optionally, the network capability related information updated by the first device includes but is not limited to at least one of the following:

[0337] The first device updates supported network capabilities;

[0338] The fifth indication information is used to indicate whether the network capability supported by the first device is open; for example, in the case of a newly supported network capability, whether the newly supported network capability supports opening; or whether the existing supported network capability is changed to be open, etc. (for example, a certain network capability is changed from restricted to be called to open, or from open to restricted to be called, etc.);

[0339] Sixth indication information, used to indicate whether the network capability supported by the first device is restricted from being called; for example, in the case of a newly supported network capability, whether the newly supported network capability is restricted from being called; or whether an existing supported network capability is restricted from being called, etc. (for example, a certain network capability is changed from being restricted to being open, or from being open to being restricted to being called, etc.);

[0340] The seventh indication information is used to indicate the type of device that is called when the network capability restriction supported by the first device is updated; for example: in the case of a newly supported network capability, the type of device that is called when the newly supported network capability restriction is added; or, the type of device that is called when the existing supported network capability restriction is changed or adjusted (for example, adding, changing or deleting the type of device that is called for a certain network capability, etc.), and the embodiments of the present application are not limited to this.

[0341] For example: the first core network device receives an update message sent by the second core network device; wherein the update message carries at least one of the following information: information related to the updated network capabilities of the terminal device, information related to the updated network capabilities of the access network device, and information related to the updated network capabilities of the second core network device. Optionally, the first core network device is a network storage functional device; and / or, the second core network device includes at least one of the following: a service consumer network functional device, a user plane functional device. Or optionally, the first core network device is a network storage functional device of a first distributed node; and / or, the second core network device includes at least one of the following: a network storage functional device of a second distributed node, a network storage functional device of a centralized node.

[0342] The following describes the process of updating the network capability of the second core network device in conjunction with the embodiment:

[0343] Embodiment 6: The service consumer NF device (i.e., the second core network element) updates the network capability to the NRF device (i.e., the first core network device); for example, based on the above embodiment 1, after the service consumer NF device has registered the network capability with the NRF device, the network capability needs to be updated, such as Figure 4 As shown, the following steps are included:

[0344] Step 41: The service consumer NF device sends an update request message (such as Nnrf_NFManagement_NFUpdate) to the NRF device to notify the NRF device of the NF configuration file updated by the service consumer NF device.

[0345] Optionally, the updated NF configuration file includes but is not limited to at least one of the following:

[0346] NF instance ID;

[0347] Updated section in the configuration file;

[0348] The updated information related to the network capabilities of the first device, such as the updated information related to the network capabilities (such as computing power capabilities, AI capabilities, security capabilities, etc.) of the service consumer NF device itself, or the updated information related to the network capabilities of the access network device transmitted by the access network device through the service consumer NF device, or the updated information related to the network capabilities of the terminal device, etc.

[0349] Step 42: The NRF device updates the NF configuration file of the service consumer NF device.

[0350] Step 43: The NRF device sends an update response message (such as Nnrf_NFManagement_NFUpdate) to the service consumer NF device to notify the service consumer NF device to confirm the NF update.

[0351] Embodiment 7: The UPF device (ie, the second core network element) updates the network capability to the NRF device (ie, the first core network device);

[0352] Specifically, after the UPF device has registered its own network capabilities with the NRF device, if the UPF device needs to update its own network capabilities to the NRF device, other core network devices (such as SMF devices, etc.) with network capabilities updated by known UPF devices can replace the UPF device to update services to the NRF device, such as the SMF device sending the updated configuration file of the UPF device to the NRF device. For example, the updated configuration file includes information related to the updated network capabilities of the UPF device.

[0353] Alternatively, when the UPF device needs to update its own network capabilities to the NRF device, the UPF device can directly perform service updates to the NRF device as an NF device (such as in a service-oriented scenario). The configuration file during the update includes information related to the updated network capabilities of the UPF device.

[0354] Embodiment 8: The NRF device of the first distribution node (i.e., the second core network device) updates the network capability to the NRF device of the second distribution node (i.e., the NRF device of other branch nodes except the first distribution node, i.e., the first core network device) or the NRF device of the centralized node (i.e., the first core network device);

[0355] Specifically, in a distributed network scenario, after the NRF device of a distributed node has registered network capabilities with an NRF device, if the NRF device of a distributed node needs to update services to NRF devices of other distributed nodes or centralized nodes, the NRF device of the distributed node can send an updated configuration file to the NRF devices of other distributed nodes or centralized nodes. The updated configuration file includes information related to the updated network capabilities of the NRF device of the distributed node, etc.

[0356] For example, the first core network device receives an update message from an access network device, and the update message carries at least one of the following information: information related to updated network capabilities of the terminal device and information related to updated network capabilities of the access network device itself. Optionally, the first core network device is a network storage function device.

[0357] The following describes the process of updating the network capability of the access network device in conjunction with the embodiments:

[0358] Embodiment 9: The RAN device updates the network capability to the NRF device (ie, the first core network device);

[0359] Specifically, after the RAN device has registered its own network capabilities with the NRF device, if the RAN device needs to update its own network capabilities to the NRF device, other core network devices (such as AMF devices, SMF devices, etc.) that know the updated network capabilities of the RAN device itself can replace the RAN device to update the service to the NRF device, such as sending the updated configuration file of the RAN device to the NRF device by the AMF device, SMF device, etc. For example, the updated configuration file includes information related to the updated network capabilities of the RAN device.

[0360] Alternatively, if the RAN device needs to update its own network capabilities to the NRF device, the RAN can also directly perform service updates to the NRF device as an NF device (such as in a service-oriented scenario). The configuration file during the update includes information related to the updated network capabilities of the RAN device.

[0361] Embodiment 10: The UE updates the network capability to the NRF device (ie, the first core network device);

[0362] Specifically, in a user-centric network scenario, the UE's own capabilities are gradually enhanced. For example, after the UE has registered its own network capabilities with the NRF device, when the UE needs to update its own network capabilities to the NRF device, other core network devices (such as AMF devices, SMF devices, etc.) that know the UE's updated network capabilities can replace the UE to update services to the NRF device, such as sending the UE's updated configuration file to the NRF device by the AMF device, SMF device, etc. For example, the updated configuration file includes information related to the UE's updated network capabilities.

[0363] Alternatively, when the UE needs to update its own network capabilities to the NRF device, it can also update the service to the NRF device through the RAN device (such as in a service-oriented scenario), and the configuration file during the update includes information related to the updated network capabilities of the UE, etc.

[0364] Optionally, the terminal device, or the access network device, or the second core network device may register its own network capabilities with the first core network device. For example, after the first core network device receives the network capability related information of the first device, it also includes:

[0365] The first core network device receives a deregistration message; wherein the deregistration message is used to instruct to deregister the first device;

[0366] The first core network device deletes the network capability related information of the first device according to the deregistration message, and determines that the first device is in an unavailable state.

[0367] That is, the first core network device performs deregistration management on the first device according to the deregistration message. For example, deregistration management is performed on at least one of the terminal device, access network device, and second core network device included in the first device.

[0368] It should be noted that deregistration management includes but is not limited to at least one of the following: deregistering the network capabilities supported by the first device; closing the opening of the network capabilities of the first device, closing the calling of the network capabilities of the first device, closing the calling restriction of the network capabilities of the first device, etc., that is, marking the first device as unavailable, etc. The embodiments of the present application are not limited to this.

[0369] For example: the first core network device receives a deregistration message sent by the second core network device, the deregistration message is used to instruct the deregistration of the first device, and the first device includes at least one of the following: a terminal device, an access network device, and the second core network device. Optionally, the first core network device is a network storage function device; and / or, the second core network device includes at least one of the following: a service consumer network function device, a user plane function device. Or optionally, the first core network device is a network storage function device of a first distribution node; and / or, the second core network device includes at least one of the following: a network storage function device of a second distribution node, a network storage function device of a centralized node.

[0370] The following describes the process of deregistering the network capability of the second core network device in conjunction with the embodiment:

[0371] Embodiment 11: The service consumer NF device (i.e., the second core network element) registers the network capability with the NRF device (i.e., the first core network device); for example, based on the above embodiment 1, after the service consumer NF device has registered the network capability with the NRF device, when it needs to register the network capability, Figure 5 As shown, the following steps are included:

[0372] Step 51: The service consumer NF device sends a deregistration request message (such as Nnrf_NFManagement_NFDeregister Request) to the NRF device to notify the NRF device of deregistering the network capability.

[0373] Step 52: The NRF device marks the service consumer NF device as unavailable. The NRF device may delete the NF configuration file of the service consumer NF device according to the NF management policy, including but not limited to: closing the network capability opening of the service consumer NF device, closing the calling of the network capability of the service consumer NF device by other devices, closing the calling restriction of the network capability of the service consumer NF device by other devices, etc.

[0374] Step 53: The NRF device sends a deregistration response message (eg, Nnrf_NFManagemnt_NFDeregister) to the service consumer NF device to notify the service consumer NF device to confirm NF deregistration.

[0375] Embodiment 12: The UPF device (i.e., the second core network element) registers network capabilities with the NRF device (i.e., the first core network device);

[0376] Specifically, after the UPF device has registered its own network capability with the NRF device, if the UPF device needs to register its own network capability with the NRF device, other core network devices (such as SMF devices, etc.) with network capabilities known to be registered by the UPF device can replace the UPF device to register the network capability with the NRF device, such as the SMF device sending a deregistration request message of the UPF device to the NRF device. For example, the deregistration request message includes relevant information about the deregistration network capability of the UPF device.

[0377] Alternatively, when the UPF device needs to register its own network capabilities with the NRF device, the UPF device can directly register the network capabilities with the NRF device as an NF device (for example, in a service-oriented scenario), and carry relevant information about the UPF device registering the network capabilities when registering.

[0378] Embodiment 13: The NRF device of the first distribution node (i.e., the second core network device) registers network capabilities with the NRF device of the second distribution node (i.e., the NRF devices of other branch nodes except the first distribution node, i.e., the first core network device) or the NRF device of the centralized node (i.e., the first core network device);

[0379] Specifically, in a distributed network scenario, after the NRF device of a distributed node has registered network capabilities with an NRF device, if the NRF device of the distributed node needs to de-register network capabilities with NRF devices of other distributed nodes or centralized nodes, the NRF device of the distributed node can send a de-registration request message to the NRF devices of other distributed nodes or centralized nodes, and the de-registration request message includes relevant information on the de-registration of the network capabilities of the NRF device of the distributed node, etc.

[0380] For example, the first core network device receives a deregistration message from an access network device, the deregistration message is used to instruct to deregister the first device, the first device includes a terminal and / or the access network device. Optionally, the first core network device is a network storage function device.

[0381] The following describes the process of deregistering network capabilities of an access network device in conjunction with an embodiment:

[0382] Embodiment 14: The RAN device registers network capabilities with the NRF device (ie, the first core network device);

[0383] Specifically, after the RAN device has registered its own network capability with the NRF device, if the RAN device needs to register its own network capability with the NRF device, other core network devices (such as AMF devices, SMF devices, etc.) that know the network capability of the RAN device to register itself can replace the RAN device to register the network capability with the NRF device, such as the AMF device, SMF device, etc. sending the deregistration request message of the RAN device to the NRF device. For example, the deregistration request message includes relevant information of the RAN device deregistering the network capability.

[0384] Alternatively, if the RAN device needs to register its own network capabilities with the NRF device, the RAN can also directly register the network capabilities with the NRF device as an NF device (such as in a service-oriented scenario), and carry relevant information about the RAN device registering the network capabilities when registering.

[0385] Embodiment 15: The UE registers network capabilities with the NRF device (ie, the first core network device);

[0386] Specifically, in a user-centric network scenario, the UE's own capabilities are gradually strengthened. For example, after the UE has registered its own network capabilities with the NRF device, when the UE needs to register its own network capabilities with the NRF device, other core network devices (such as AMF devices, SMF devices, etc.) that know the UE's own network capabilities to register can replace the UE to register the network capabilities with the NRF device, such as sending the UE deregistration request message to the NRF device by the AMF device, SMF device, etc. For example, the deregistration request message includes relevant information about the UE's deregistration network capabilities.

[0387] Alternatively, when the UE needs to register its own network capabilities with the NRF device, it can also register the network capabilities with the NRF device through the RAN device (such as in a service-oriented scenario), and carry relevant information about the UE's registration of network capabilities when registering.

[0388] Optionally, the first core network device may also support network capability subscription, for example, a terminal device, an access network device or a second core network device may subscribe to the first core network device for network capabilities of other terminal devices, other access network devices or other second core network devices. Specifically, after the first core network device receives the network capability related information of the first device, it also includes:

[0389] The first core network device sends a subscription message to the second device; wherein the subscription message carries information related to the network capability of the first device, or indication information for instructing the first device to deregister.

[0390] It should be noted that the second device is a device different from the first device. For example, the first device includes one of a terminal device, an access network device, and a second core network device. The second device may also include at least one of a terminal device, an access network device, and a second core network device that are different from the first device. For example, taking the example that the second device includes an access network device, the access network device can subscribe to the network capabilities of at least one of the terminal device, other access network devices, and the second access network device. In this way, when the first core network device determines that the first device registers, updates, or deregisters the network capability, and the first device includes the device subscribed by the second device, the first core network device sends a subscription message to the second device. In other words, the second device is a device that subscribes to the network capability-related content of the first device (such as subscribing to the first device's registration, update, deregistration network capability and other related content).

[0391] For example: when the network capability-related information of the first device includes network capability-related information of the terminal device, if other terminal devices or access network devices or second core network devices have subscribed to the network capability of the terminal device, the first core network device can send the network capability-related information of the first device to other terminal devices or access network devices or second core network devices that request subscription.

[0392] For example: when the network capability-related information of the first device includes the network capability-related information of the first access network device, if the terminal device or the second access network device (that is, other access network devices) or the second core network device has subscribed to the network capability of the first access network device, the first core network device can send the network capability-related information of the first device to the terminal device or other access network device or the second core network device that requested the subscription.

[0393] For example: when the network capability-related information of the first device includes network capability-related information of the second core network device, if the terminal device or access network device or other second core network device has subscribed to the network capability of the second core network device, the first core network device can send the network capability-related information of the first device to the terminal device or access network device or other second core network device that requested the subscription.

[0394] Specifically, referring to the above embodiments 1 to 15, when a new NF device is registered, or a registered NF device updates information related to network capabilities, or a registered NF device deregisters, or a new UPF device is registered, or a registered UPF device updates information related to network capabilities, or a registered UPF device deregisters, or a new RAN is registered, or a registered RAN updates information related to network capabilities, or a registered RAN device deregisters, or a new UE is registered, or a registered UE updates information related to network capabilities, or a registered UE deregisters, the NRF device can be triggered to send a subscription message to a subscriber (i.e., a second device) who has subscribed to NF status notifications, UPF status notifications, RAN status notifications, or UE status notifications. The subscription message can inform the second device (such as NF device or UPF device or RAN device or UE, etc.) of the relevant content of registration / update / deregistration, etc. The embodiments of the present application are not limited to this.

[0395] The above scheme of the present application can realize the enhancement of network function management by core network equipment (such as NRF), specifically, by carrying its own network capability information when registering / updating / de-registering with NRF services through NF, RAN, UPF or UE, thereby enhancing NRF management of network elements and management content, being more adaptable to 6G network architecture, and improving service efficiency.

[0404] Optionally, before the access network device sends the network capability related information of the first device to the first core network device, the method further includes:

[0417] It should be noted that the information processing method on the access network device side of the embodiment of the present application and the information processing method on the first core network side are based on the same inventive concept.
