For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0235] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0236] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0237] The following is an introduction to the relevant technologies involved in this disclosure:

[0238] 1. NRF equipment

[0239] Refer to Figure 1, which shows the architecture of the non-roaming 5G system. This architecture involves the control plane network slice selection function (NSSF) device, network exposure function (NEF) device, policy and control function (PCF) device, unified data management (PCF) device, application function (AF) device, NRF device, as well as authentication service function (ASF) device, access and mobility management function (AMF) device, session management function (SMF) device. Of course, the control plane can also involve other core network devices, etc., which will not be repeated here.

[0240] 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.

[0241] Among them, the NRF device supports the service discovery function, that is, it receives NF discovery requests from NF instances or Service Communication Proxy (SCP), and provides the information of the discovered NF instances (discovered) to the NF instances or SCP; maintains the NF profiles of available NF instances and their supported services.

[0242] The NF services provided by NRF include but are not limited to the following:

[0243] Network Function Registration (Nnrf_NFManagement_NFRegister): Registers the consumer NF in the NRF by providing the NRF with its NF profile, and the NRF marks the consumer NF as available. For example, the registration may include the NF type, NF instance identifier (ID), the name of the supported NF services, and the Public Land Mobile Network Identifier (PLMN ID).

[0244] Network Function Update (Nnrf_NFManagement_NFUpdate): Provides the NRF with the updated NF configuration file from the NF consumer. For example, the update can include the NF instance ID. In some embodiments, if the entire NF configuration file is replaced, the update should include the entire NF configuration file. If a partial NF configuration file is updated, the update should include the NF configuration file elements that need to be updated.

[0245] Network Function Deregistration or Deregistration (Nnrf_NFManagement_NFDeregister): Notifies the NF consumer that it is unavailable to the NRF. For example, the NF instance ID can be carried during deregistration or deregistration.

[0246] 2. Open Network Capabilities

[0247] With the development of artificial intelligence (AI), network intelligence has become an inevitable trend in future network development. Especially in 6G networks, AI will be integrated into the network architecture, enabling endogenous intelligence. Future mobile networks will need to support ubiquitous applications, especially advanced applications. This requires a seamless integration of network and service. Networks need to be more agile, intelligent, and open, providing more channels and public services. This will enable mutual awareness and collaboration between the network and applications, optimizing the user and application experience and maximizing network value.

[0248] Network capability exposure provides an open environment for both traditional network openness and new capabilities such as intelligence, computing power, and synergy. Future mobile networks will offer more flexible means of exposing network capabilities, such as local openness, user-plane openness, combined or nested openness, and multi-party collaborative openness. Capability exposure will provide a shared environment for multi-party providers, coupled with appropriate incentive mechanisms. By offering a flexible and dynamic registration mechanism, capabilities can be released and invoked on demand. Capability exposure will be delivered through user-friendly service-oriented interfaces, benefiting from the comprehensive protection of the network's inherent intelligence and security.

[0249] 3. RAN Service-Oriented

[0250] To meet the agility, flexibility, and scalability requirements of diverse 5G services, network transformation toward virtualization and cloudification is inevitable. Cloud Radio Access Network (Cloud RAN) has gained widespread favor among global operators due to its two core features: a universal hardware platform and cloud-native technologies. 6G wireless networks will not only focus on Cloud RAN but also on service-oriented RAN.

[0251] To meet the demands for rapid rollout of diverse services, the 5G core network utilizes a service-oriented architecture as its network infrastructure and has undergone in-depth optimization based on the separation of the control and user planes. The 5G core network control plane is modularly decomposed into distinct network functions. These decoupled network functions can be independently scaled, evolved, and deployed on demand. Each network function can provide multiple network function services, enabling on-demand customization of core network functions and flexible support for diverse business scenarios and requirements.

[0252] Next-generation radio access networks (RANs) require restructuring wireless networks into service-oriented RANs (Service-Based RANs) with finer-grained functionality from a service capability perspective. Defining service-based interfaces between RAN and core network services will introduce new interaction methods for end-to-end network processes while minimizing the impact of new cross-domain functionality on existing services. Defining service-based interfaces between RAN and third-party services will enable more timely and multi-dimensional exposure of wireless network capabilities. Integrated orchestration and management of RAN and core network (CN) services will reduce network-wide O&M complexity and enhance the network's adaptability to new services.

[0253] Taking into account multiple aspects such as industry maturity and technological maturity, the development of service-oriented RAN may include the following five levels: service-oriented control plane interfaces to achieve direct cross-domain functional access; service-oriented RAN control plane to facilitate end-to-end process optimization; service-oriented RAN user plane to create the ultimate cross-layer transmission experience; RAN service-oriented 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; and stimulate UE service capabilities to achieve end-to-network service capability sharing.

[0254] 4. UPF service

[0255] The 5G core network interacts via a service-based interface (SBI). However, 5G service-based capabilities are limited to the control plane. User plane devices (such as the UPF) do not yet offer service-based interfaces for use by other core network devices. User plane network function devices require further service-based transformation to provide external services.

[0256] 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.

[0257] The content of UPF service is shown in Table 1:

[0258] Table 1

[0259] The disclosed embodiments provide an information processing method, a core network device, an access network device, and a terminal device, which address the problem that current core network devices cannot meet the requirements for enhanced management of network capabilities. The method and the core network device (or access network device or terminal device) are based on the same patent application concept. Since the principles for solving the problem 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 any repetitions will not be repeated.

[0260] As shown in FIG2 , an embodiment of the present disclosure provides an information processing method, comprising the following steps:

[0261] Step 21: The first core network device receives network capability-related information of the first device.

[0262] Among them, the first device includes at least one of the following: terminal equipment, access network equipment, and second core network equipment.

[0263] That is, the network capability-related information of the first device includes at least one of the following:

[0264] Information related to the network capabilities of the terminal device;

[0265] Information related to the network capabilities of access network equipment;

[0266] Network capability information of the second core network device.

[0267] In some embodiments, the first core network device may be an NRF device.

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

[0270] 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. In some embodiments, 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 an NRF device of a 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 an NRF device of a centralized node or an NRF device of a second distribution node, etc.).

[0271] Step 22: The first core network device performs network function management based on the network capability related information of the first device.

[0272] In some embodiments, 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.

[0273] 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.

[0274] In the above solution, the first core network device receives information related to the network capabilities of the first device, which includes at least one of the following: a terminal device, an access network device, and a second core network device. In this way, the first core network device can manage the network functions of at least one of the terminal device, the access network device, and the second core network device based on the information related to the network capabilities of the first device, thereby enhancing the network functions of the first core network device and resolving the current problem of being unable to meet the enhanced management requirements of the network capabilities of the core network devices. 。

[0275] In some embodiments, the network capability-related information of the first device includes at least one of the following:

[0276] 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 disclosure are not limited thereto.

[0277] first indication information, used to indicate whether the network capability supported by the first device is open;

[0278] Second indication information, used to indicate whether the network capability supported by the first device is restricted from being called;

[0279] The third indication information is used to indicate that the network capability supported by the first device limits the type of device being called.

[0280] In some embodiments, the network capability related information of the first device may also include: fourth indication information for indicating the device type supported for network capability exposure, etc. Of course, the network capability related information of the embodiment of the disclosure is not limited to and may also include other network capability related information, etc., and the embodiment of the disclosure is not limited thereto.

[0281] For example, information related to the network capabilities of a terminal device may include at least one of the following:

[0282] Network capabilities supported by the terminal device;

[0283] 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 disclosure are not limited to this.

[0284] 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 disclosure are not limited to this.

[0285] 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 disclosure are not limited to this.

[0286] For example, information related to the network capabilities of access network equipment includes at least one of the following:

[0287] Network capabilities supported by access network equipment;

[0288] 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 disclosure are not limited to this.

[0289] 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 disclosure are not limited to this.

[0290] 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 disclosure are not limited to this.

[0291] For example, information related to the network capabilities of the second core network device includes at least one of the following:

[0292] Network capabilities supported by the second core network equipment;

[0293] 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 disclosure are not limited to this.

[0294] 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 disclosure are not limited to this.

[0295] 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 disclosure are not limited to this.

[0296] In some embodiments, the first core network device receiving the network capability-related information of the first device includes:

[0297] The first core network device receives at least one of the following information sent by the access network device: network capability-related information of the terminal device and network capability-related information of the access network device;

[0298] and / or,

[0299] The first core network device receives at least one of the following information sent by the second core network device: network capability-related information of the terminal device, network capability-related information of the access network device, and network capability-related information of the second core network device.

[0300] In this embodiment, the access network device may provide the first core network device with information related to its own network capabilities, or may provide the first core network device with information related to the network capabilities of the corresponding terminal device. The second core network device may provide the first core network device with information related to its own network capabilities, or may provide the first core network device with information related to the network capabilities of the corresponding access network device, or may provide the first core network device with information related to the network capabilities of the terminal device, or may provide the first core network device with information related to the network capabilities of other core network devices (for example, an SMF device may provide the first core network device with information related to the network capabilities of a UPF device, etc.), but the embodiments of the present disclosure are not limited thereto.

[0301] In some embodiments, 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:

[0302] The first core network device receives a registration message, wherein the registration message carries network capability related information of the first device;

[0303] The first core network device performs network function management according to the network capability related information of the first device, including:

[0304] 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.

[0305] 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.

[0306] 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. In some embodiments, 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 in some embodiments, 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.

[0307] The following describes the process of registering network capabilities of the second core network device with reference to an embodiment:

[0308] Example 1: A service consumer NF device (i.e., a second core network element) registers network capabilities with an NRF device (i.e., a first core network device), as shown in FIG3 , including the following steps:

[0309] 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 profile of the service consumer NF device when the service consumer NF device starts working for the first time.

[0310] In some embodiments, the NF configuration file includes but is not limited to at least one of the following:

[0311] NF type;

[0312] NF instance ID;

[0313] The name of the supported NF service;

[0314] PLMN ID;

[0315] 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.

[0316] 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.

[0317] 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 that it accepts the NF registration.

[0318] Example 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);

[0319] 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 replace the UPF device to register services with the NRF device. For example, the SMF device sends 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.

[0320] Alternatively, when the UPF device needs to register its own network capabilities with the NRF device, the UPF device 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 UPF device.

[0321] 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);

[0322] Specifically, in a distributed network scenario, the NRF device of a distribution node can register for 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.

[0323] For example, the first core network device receives a registration message sent by an access network device, the registration message carrying 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. In some embodiments, the first core network device is a network storage function device.

[0324] The following describes the process of registering network capabilities of an access network device with reference to an embodiment:

[0325] Embodiment 4: The RAN device registers network capabilities with the NRF device (i.e., the first core network device);

[0326] 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 are aware of the network capabilities of the RAN device can register services with the NRF device on behalf of the RAN device. For example, the AMF device, SMF device, etc. send the configuration file of the RAN device to the NRF device. For example, the configuration file includes information related to the network capabilities of the RAN device.

[0327] 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 (for example, in a service-oriented scenario). The configuration file during registration includes information related to the network capabilities of the RAN device.

[0328] Embodiment 5: The UE registers network capabilities with the NRF device (i.e., the first core network device);

[0329] Specifically, in a user-centric network scenario, the UE's own capabilities are gradually enhanced. 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 are aware of the UE's own network capabilities can replace the UE in registering services with the NRF device. For example, the AMF device, SMF device, etc. send the UE's configuration file to the NRF device. For example, the configuration file includes information related to the UE's network capabilities.

[0330] 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). The configuration file during registration includes information related to the network capabilities of the UE.

[0331] In some embodiments, 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 the network capability-related information of the first device, including:

[0332] The first core network device receives an update message; wherein the update message carries network capability related information of the first device;

[0333] The first core network device performs network function management according to the network capability related information of the first device, including:

[0334] The first core network device updates the network capability related information of the first device according to the update message.

[0335] That is, the first core network device performs network capability update management for the first device, such as performing network capability update management for at least one of the terminal device, the first access network device, and the second core network device included in the first device.

[0336] 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 updated network capabilities of the first device, including but not limited to at least one of the following: information related to the updated network capabilities of the terminal device, information related to the updated network capabilities of the access network device, information related to the updated network capabilities of the second core network device, etc.

[0337] In some embodiments, the network capability related information updated by the first device includes but is not limited to at least one of the following:

[0338] The first device updates supported network capabilities;

[0339] 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 changing whether an existing supported network capability is open, etc. (for example, changing a certain network capability from restricted to open, or from open to restricted);

[0340] Sixth indication information, used to indicate whether the first device updates a supported network capability to be restricted from being invoked; for example, if a newly supported network capability is newly added, whether the newly supported network capability is restricted from being invoked; or, changing whether an existing supported network capability is restricted from being invoked (for example, changing a certain network capability from being restricted to being open, or from being open to being restricted);

[0341] 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 restricted; or, the type of device that is called when the existing supported network capability restriction is adjusted (for example, the type of device that is called when adding, changing or deleting the restriction for a certain network capability, etc.), and the embodiments of the present disclosure are not limited to this.

[0342] 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. In some embodiments, 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 in some embodiments, 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.

[0343] The following describes the process of updating the network capability of the second core network device in conjunction with an embodiment:

[0344] Example 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-mentioned Example 1, after the service consumer NF device has registered the network capability with the NRF device, it is necessary to update the network capability, as shown in Figure 4, including the following steps:

[0345] 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 updated NF configuration file of the service consumer NF device.

[0346] In some embodiments, the updated NF configuration file includes but is not limited to at least one of the following:

[0347] NF instance ID;

[0348] The updated part of the configuration file;

[0349] The updated network capability-related information of the first device, such as the network capability-related information (such as computing power capability, AI capability, security capability, etc.) updated by the service consumer NF device itself, or the network capability-related information updated by the access network device transmitted by the access network device through the service consumer NF device, or the network capability-related information updated by the terminal device, etc.

[0350] Step 42: The NRF device updates the NF configuration file of the service consumer NF device.

[0351] 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.

[0352] Example 7: The UPF device (i.e., the second core network network element) updates the network capability to the NRF device (i.e., the first core network device);

[0353] 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.) that know the network capabilities updated by the UPF device can replace the UPF device to update the service to the NRF device. For example, the SMF device sends the configuration file updated by 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.

[0354] 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.

[0355] 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 the 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);

[0356] Specifically, in a distributed network scenario, after the NRF device of a distribution node has registered network capabilities with an NRF device, if the NRF device of a distribution node needs to update services to NRF devices of other distribution nodes or centralized nodes, the NRF device of the distribution node can send an updated configuration file to the NRF devices of other distribution nodes or centralized nodes. The updated configuration file includes information related to the updated network capabilities of the NRF device of the distribution node, etc.

[0357] For example, the first core network device receives an update message from an access network device, the update message carrying 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. In some embodiments, the first core network device is a network storage device.

[0358] The following describes the process of updating network capabilities of an access network device in conjunction with an embodiment:

[0359] Embodiment 9: The RAN device updates the network capability to the NRF device (ie, the first core network device);

[0360] 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 can replace the RAN device to perform service updates to the NRF device. For example, the AMF device, SMF device, etc. send the updated configuration file of the RAN device to the NRF device. For example, the updated configuration file includes information related to the updated network capabilities of the RAN device.

[0361] 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.

[0362] Embodiment 10: The UE updates the network capability to the NRF device (ie, the first core network device);

[0363] 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 are aware of the UE's updated network capabilities can replace the UE to update services to the NRF device. For example, the AMF device, SMF device, etc. send the UE's updated configuration file to the NRF device. For example, the updated configuration file includes information related to the UE's updated network capabilities.

[0364] 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). The configuration file during the update includes information related to the updated network capabilities of the UE.

[0365] In some embodiments, 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:

[0366] The first core network device receives a deregistration message; wherein the deregistration message is used to instruct deregistration of the first device;

[0367] 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.

[0368] That is, the first core network device performs deregistration management on the first device according to the deregistration message, for example, performing deregistration management on at least one of the terminal device, the access network device, and the second core network device included in the first device.

[0369] 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 disclosure are not limited to this.

[0370] 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. In some embodiments, 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 in some embodiments, 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.

[0371] The following describes the process of deregistering network capabilities of the second core network device in conjunction with an embodiment:

[0372] Example 11: The service consumer NF device (i.e., the second core network element) registers network capabilities with the NRF device (i.e., the first core network device). For example, based on the above-mentioned Example 1, after the service consumer NF device has registered network capabilities with the NRF device, when it needs to register the network capabilities, as shown in FIG5 , the following steps are included:

[0373] 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.

[0374] 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: disabling the network capability exposure of the service consumer NF device, disabling other devices from calling the network capability of the service consumer NF device, and disabling the restriction of the network capability of the service consumer NF device from being called by other devices.

[0375] 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.

[0376] Example 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);

[0377] Specifically, after the UPF device has registered its own network capabilities with the NRF device, if the UPF device needs to register its own network capabilities with the NRF device, other core network devices (such as SMF devices, etc.) with network capabilities known to the UPF device can replace the UPF device to register the network capabilities with the NRF device. For example, the SMF device sends 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 capabilities of the UPF device.

[0378] 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.

[0379] 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);

[0380] Specifically, in a distributed network scenario, after the NRF device of a distribution node has registered network capabilities with an NRF device, if the NRF device of the distribution node needs to register network capabilities with NRF devices of other distribution nodes or centralized nodes, the NRF device of the distribution node can send a deregistration request message to the NRF devices of other distribution nodes or centralized nodes. The deregistration request message includes relevant information on the deregistration of network capabilities of the NRF device of the distribution node, etc.

[0381] For example, the first core network device receives a deregistration message from an access network device, the deregistration message being used to instruct deregistration of the first device, the first device including a terminal and / or the access network device. In some embodiments, the first core network device is a network storage function device.

[0382] The following describes the process of deregistering network capabilities of an access network device in conjunction with an embodiment:

[0383] Embodiment 14: The RAN device registers network capabilities with the NRF device (i.e., the first core network device);

[0384] Specifically, after the RAN device has registered its own network capabilities with the NRF device, 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 the network capabilities with the NRF device on behalf of the RAN device. For example, the AMF device, SMF device, etc. sends a deregistration request message of the RAN device to the NRF device. For example, the deregistration request message includes relevant information about the RAN device's deregistration network capabilities.

[0385] 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 (for example, in a service-oriented scenario), and carry relevant information about the RAN device registering the network capabilities when registering.

[0386] Embodiment 15: The UE registers network capabilities with the NRF device (i.e., the first core network device);

[0387] 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 register its own network capabilities with the NRF device, other core network devices (such as AMF devices, SMF devices, etc.) that are aware of the UE's own network capabilities can replace the UE in registering the network capabilities with the NRF device. For example, the AMF device, SMF device, etc. send the UE deregistration request message to the NRF device. For example, the deregistration request message includes relevant information about the UE's deregistration network capabilities.

[0388] 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.

[0389] In some embodiments, 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 network capabilities of other terminal devices, other access network devices, or other second core network devices from the first core network device. Specifically, after the first core network device receives the network capability related information of the first device, the following steps are further included:

[0390] The first core network device sends a subscription message to the second device; wherein the subscription message carries network capability-related information of the first device, or indication information for instructing the first device to deregister.

[0391] 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 of the second device including 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 registration, update, deregistration network capability and other related content of the first device).

[0392] For example: when the network capability-related information of the first device includes the 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.

[0393] 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 subscribes 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 requests subscription.

[0394] For example: when the network capability-related information of the first device includes the 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 subscription.

[0395] Specifically, referring to the above embodiments 1 to 15, when a new NF device registers, or a registered NF device updates network capability-related information, or a registered NF device deregisters, or a new UPF device registers, or a registered UPF device updates network capability-related information, or a registered UPF device deregisters, or a new RAN registers, or a registered RAN updates network capability-related information, or a registered RAN device deregisters, or a new UE registers, or a registered UE updates network capability-related information, or a registered UE deregisters, the NRF device can be triggered to send a subscription message to the subscriber (i.e., the second device) that has subscribed to the NF status notification, or the UPF status notification, or the RAN status notification, or the UE status notification. The subscription message can inform the second device (such as the NF device or the UPF device or the RAN device or the UE, etc.) of the relevant content of registration / update / deregistration, etc. The embodiments of the present disclosure are not limited to this.

[0396] The above-mentioned scheme disclosed in the present invention can realize the enhancement of network function management of 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.

[0397] As shown in FIG6 , the embodiment of the present disclosure provides an information processing method, comprising the following steps:

[0398] Step 61: The access network device sends network capability related information of the first device to the first core network device or the second core network device.
