Description

Background Art

[0002] With the rapid development of communication technology, information communication between networks has become one of the current focuses. The existing 5G (5th Generation Mobile Communication Technology) network uses two levels of NRF (NF Repository Function) for service management. Among them, the provincial NRF is responsible for the service registration and discovery of the control plane network elements within the province, and the backbone NRF is mainly responsible for forwarding the cross-provincial network element discovery query and response messages. Figure 1 For example, when the service consumer in Province A, such as AMF (Access and Mobility Management Function) 110 in Province A, needs to provide initial registration / session establishment services for users belonging to Province B, it needs to initiate a UDM (Unified Data Management) discovery request to the NRF (NF Repository Function) 120 in this province to query the user's contract data, carrying the user's SUPI (Subscription Permanent Identity) identifier as a discovery parameter. If the NRF 120 of this province finds that the user number segment does not match the UDM of this province, it will forward the discovery request to the backbone NRF 130, and the backbone NRF 130 will forward it to the NRF 140 of Province B based on the number segment configuration of different provinces. The NRF 140 of Province B stores the registration information of the UDM 150 of this province, and then returns the service configuration information of the UDM 150 of this province, such as the address and other information, to the backbone NRF 130 through the service discovery response, and then the backbone NRF 130 forwards it to the vNRF of Province A. Finally, after the AMF of Province A obtains the UDM configuration information of Province B, it caches the discovery result and directly initiates a service request to the UDM of Province B. Among them, for the UE (User Equipment) or NF (Network Function) of Province B, the AMF of Province A is vAMF (visited AMF, visited access and mobility management function), the NRF is vNRF (visited NRF, visited network storage function), the NRF of Province B is hNRF (homeNRF, local network storage function), and the UDM is hUDM (home UDM, local unified data management function).

[0003] However, the above network information management method is limited to cross-network service discovery and request of user data network elements, and cannot be applied to the application scenarios of diversified cross-network collaborative services. In addition, the interaction process is complex and the timeliness is poor, and it is impossible to carry out efficient collaboration. Each participating network needs to obtain more comprehensive service information of the collaborative network. For example, it cannot be applied to the 6G (6th Generation Mobile Communication Technology) network. Therefore, how to effectively manage network information is a technical problem that needs to be solved in the existing technology.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0026] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0027] The exemplary embodiment of the present disclosure first provides a network information management method, which is applied to a network information management system, wherein the network service system at least includes a first network node, a central network node, and a second network node. The network node may include a NF (Network Function) of the network node, a service agent, etc. The first network node may refer to a network node to be registered, the second network node may refer to a registered network node, and the central network node refers to a management center for network service configuration information.

[0028] Figure 2The system architecture of a network information management method in this exemplary embodiment is shown, and the system may include a distributed network A 210, that is, a first network node, a distributed network B 220, that is, a second network node, and a central network 230, that is, a central network node. Among them, the distributed network A 210 may include multiple NFs 211 and a service agent 212 of the distributed network A, the distributed network B 220 may include multiple NFs 221 and a service agent 222 of the distributed network B, and the central network 230 may include multiple NFs 231 and a service agent 232 of the central network. The service agent may serve as a registration management center for internal network services to synchronize node configuration information of each participating network. Node configuration information may include: network identification, such as MCC (mobile device network code) + MNC (mobile network code) + specific number, or a completely new numbering system; network type: central network / distributed network; service agent address information, such as IP address or FQDN (Fully qualified domain name); location and coverage information; network capability information exposed to the outside on demand: network functions, including NF service list and supported parameters, such as number segments, DNN (Data Network Name) and user authentication methods, but does not include privacy information such as each NF instance identification and address; network performance, including capacity and load, etc.

[0029] Specifically, the service agent of the central network acts as a network service configuration information management center, which can manage the registration, change and notification of each distributed network service configuration information, and can monitor the status of each distributed network through a heartbeat mechanism. In this exemplary embodiment, the distributed network can generate its own node configuration information of network services as needed, and register and update it to the service agent of the central network through the service agent, and receive the change notification of the node configuration information of other network nodes from the service agent of the central network. The service agent can also serve as an anchor point for cross-network collaboration, responsible for processing and forwarding cross-network service request and response messages, and topologically hide the message content involving internal service privacy to ensure security.

[0030] Figure 3 The system architecture of another network information management method in this exemplary embodiment is shown. In this exemplary embodiment, the service agent can be an enhanced service agent jointly set up by NRF (NF Repository Function) and SCP (Service Communication Proxy) after enhancing the public. Figure 3As shown, the network information system may include a distributed network A 310, i.e., a first network node, a distributed network B 320, i.e., a second network node, and a central network 330, i.e., a central network node. The distributed network A 310 may include multiple NFs 311 and an enhanced service agent 312 of the distributed network A, the enhanced service agent 312 may include an NRF 3121 of the distributed network A and an SCP 3122 of the distributed network A, the distributed network B 320 may include multiple NFs 321 and an enhanced service agent 322 of the distributed network B, the enhanced service agent 322 may include an NRF 3221 of the distributed network B and an SCP 3222 of the distributed network B, the central network 330 may include multiple NFs 331 and an enhanced service agent 332 of the central network, the enhanced service agent 332 may include an NRF 3321 of the central network and an SCP 3322 of the central network.

[0031] In addition to managing the registration and discovery of NFs within the core network, the enhanced NRF can also be responsible for the synchronization of the network configuration information lists of each participating network. Among them, the NRF of the central network can serve as the network configuration information management center, and the NRF of the distributed network needs to register and update the node configuration information of its own network to the central node NRF, and receive update notifications of the node configuration information of other network nodes from the central network NRF; the enhanced SCP is not only responsible for the indirect communication of NFs within the core network in D mode (a communication technology), but also for the forwarding of cross-network service requests and responses and additional processing, such as topology hiding and the generation and verification of security tokens, to ensure the security of cross-network collaboration; SCP can obtain the configuration information of the target network from NRF through subscription or discovery, such as carrying service discovery parameters, to perform cross-network collaborative processing.

[0032] In this exemplary embodiment, the node configuration information includes: network number, MCC+MNC+specific network identifier; network type, central network / distributed network; SCP address, IP or FQDN format (since cross-network service collaboration does not require service discovery through NRF, there is no need to expose NRF address information); location and coverage information; network capability information exposed to the outside on demand: network functions, including the list of NF services exposed to the outside and supported parameters, such as number segments, DNNs, and user authentication methods, but excluding detailed privacy information such as the identifier and address of each NF instance; network performance, including capacity and load, etc.

[0033] The following is combined with Figure 4 This exemplary embodiment is further described as follows. Figure 4 As shown, the network information management method may include the following steps S410-S430:

[0034] Step S410, in response to the central network node receiving a network registration request sent by the first network node, adding the first node configuration information to the central network configuration information; the network registration request includes at least the first node configuration information of the first network node, and the central network configuration information includes at least the central node configuration information of the central network node and / or the second node configuration information of the second network node.

[0035] The first network node may be any node that needs to be registered with the network, and there may be multiple first network nodes, such as network node A1 to be registered, network node A2 to be registered, etc. The second network node may be any node that has performed network registration, and there may be multiple second network nodes, such as registered network node B1, registered network node B2, etc. In this exemplary embodiment, when the first network node is operating normally, for example, after network A is online, a network registration request may be sent to the central network node to join the network management of the central network node. The network registration request refers to a request sent by the first network node to join the central network node for network management, and the network registration request may at least include the first node configuration information of the first network node.

[0036] In this exemplary embodiment, the node configuration information may include a network number or identifier, such as MCC+MNC+specific number, or a completely new numbering system; a network type, such as a central network / distributed network; address information of a service agent, such as an IP address or FQDN; location and coverage information; network capability information exposed to the outside on demand, such as network functions, including a NF service list and supporting parameters, such as number segments, DNNs, and user authentication methods, but excluding privacy information such as the identifier and address of each NF instance, and network performance, including capacity and load, etc.

[0037] The first node configuration information refers to service configuration information related to the first network node. For example, when the first network node is a NF of a distributed network, the first node configuration information may include an identifier of the NF of the first network node, a service list of the NF, a type of NF, an IP (Internet Protocol) address or support parameters, etc. The support parameters may include a database segment, or support parameters for providing AI (Artificial Intelligence) functions or other 6G functions.

[0038] The central network node receives the network registration request sent by the first network node, and adds the first node configuration information to the central network configuration information. The central network configuration information refers to information configured by the central network node side for maintaining and managing the node configuration information of each network node, which can be managed in the form of a list, for example, it can be a network configuration information list maintained by the central network node side. In this exemplary embodiment, the central network configuration information at least includes the central node configuration information of the central network node and / or the second node configuration information of the second network node, that is, the central network node can configure a network configuration information list to manage the configuration information of itself or other registered network nodes through the network configuration information list.

[0039] In an exemplary embodiment, the first network node may include a network function NF of the first distributed network and a service agent of the first distributed network; the first network node sending a network registration request to the central network node may include the following steps:

[0040] After the network function instance of the first distributed network goes online, it can first register its own configuration information to the service agent of the first distributed network, for example, register information such as NF identification, NF service list, IP address, and supported service parameters to the service agent of the first distributed network; after the service agent of the first distributed network determines that all planned NFs are online, it can generate first node configuration information and use the first node configuration information to initiate a network registration request to the central network node.

[0041] It should be noted that the configuration information includes explicit configuration information and implicit configuration information. In this exemplary embodiment, explicit configuration information can be extracted from its own configuration information to generate the first node configuration information and send it to the central network node. For example, after the service agent of the first distributed network determines that all planned NFs are online, it can hide the implicit configuration information such as the NF instance identifier and IP address, and only extract the explicit configuration information such as the NF type and support parameters to generate the first node configuration information.

[0042] Step S420, sending registration request response information to the first network node through the central network node, so that the first network node synchronously adds central node configuration information and / or second node configuration information according to the registration request response information; the registration request response information includes the central network configuration information.

[0043] After receiving the network registration request including the first node configuration information, the central network node can add the first node configuration information to the central network configuration information after successful verification. Then, the registration request response information can be returned to the first network node to notify the first network node of the result of its registration request processing. The registration request processing result may include the central node configuration information of the central network node and / or the second node configuration information of the second network node. The central node configuration information and the second node configuration information, similar to the first node configuration information, may include the configuration information of the network node, such as relevant information of the NF, or supported service parameters, etc. After receiving the registration request response information, the first network node can synchronously add the central node configuration information and the second node configuration information to the node. For example, the node configuration information of each network node can also be managed by maintaining the first network configuration information list.

[0044] Step S430, in response to the first network node meeting the preset condition, sending notification information including the first node configuration information to the second network node through the central network node, so that the second network node adds the first node configuration information to the second network configuration information according to the notification information.

[0045] Finally, when the first network node meets the preset conditions, the central network node can also send a notification message containing the first node configuration information to the second network node, so as to add the first node configuration information to the second network configuration information, and realize the information synchronization of the network configuration information in each network node. Among them, the second network configuration information can be a local network configuration information list configured on the second network node side, and the notification message can include the first node configuration information of the first network node. When the second network node receives the notification message, it can extract the first node configuration information from it and save it in the local second network configuration information. In addition, the notification message can also include the central node configuration information of the central network node, so that the second network node can synchronously update the central node configuration information while saving the first node configuration information.

[0046] In this exemplary embodiment, the first network node satisfies the preset condition, which may include, when the state of the first network node satisfies the preset condition, for example, when the state of the first network node is online, normally connected, etc., sending notification information including the configuration information of the first node to the second network node.

[0047] Based on the above description, in this exemplary embodiment, in response to the central network node receiving a network registration request sent by the first network node, the first node configuration information is added to the central network configuration information; the network registration request at least includes the first node configuration information of the first network node, and the central network configuration information at least includes the central node configuration information of the central network node and / or the second node configuration information of the second network node; a registration request response message is sent to the first network node through the central network node, so that the first network node synchronously adds the central node configuration information and / or the second node configuration information according to the registration request response information; the registration request response information includes the central network configuration information; in response to the first network node satisfying a preset condition, a notification message containing the first node configuration information is sent to the second network node through the central network node, so that the second network node adds the first node configuration information to the second network configuration information according to the notification information. On the one hand, this exemplary embodiment proposes a new network information management method. Different from the prior art, when network information interaction is performed, it is necessary to achieve information synchronization through complex and cumbersome interactive operations between multiple network elements or devices. This exemplary embodiment can achieve synchronization of node configuration information of each network node based on a simple and convenient process; on the other hand, this exemplary embodiment can synchronize the first node configuration information to the second network configuration information in a timely manner when the first network node meets the preset conditions, thereby achieving accurate monitoring of the first network node and effective updating of the node configuration information in each network node.

[0048] In an exemplary embodiment, in response to the first network node satisfying a preset condition, sending notification information including the configuration information of the first node to the second network node through the central network node may include:

[0049] The central network node monitors the first network node, and in response to monitoring that the first network node meets a preset condition, sends notification information including configuration information of the first node to the second network node.

[0050] The central network node monitors the first network node, which may be monitoring the status of the first network node, and the status of the first network node may include the normal operation of the network of the first network node, online, faulty or offline, etc. In order to ensure that the network configuration information in each network node can be synchronized in time, so as to effectively manage the node configuration information of multiple network nodes, this exemplary embodiment may monitor the first network node through the central network node, so that the central network node can send notification information containing the configuration information of the first node to the second network node when monitoring that the first network node meets the preset condition, and execute the corresponding instruction.

[0051] Among them, the corresponding instructions may include updating the central network configuration information, such as modifying the first node configuration information of the first network node, or deleting the first node configuration information of the first network node. The corresponding instructions may also include sending a notification to the second network node so that the second network node updates or deletes the first node configuration information in the second network configuration information, etc.

[0052] In an exemplary embodiment, the central network node monitoring the first network node may include:

[0053] A heartbeat communication connection is established between the central network node and the first network node according to a preset heartbeat cycle interval, so that the central network node monitors the first network node through the heartbeat communication connection.

[0054] This exemplary embodiment can establish a heartbeat communication connection between the central network node and the first network node according to a preset heartbeat period, so that the central network node monitors the first network node through the heartbeat communication connection, for example, monitors the status of the first network node, and the first network node meets the preset condition, which may be the case where the status of the first network node meets the preset condition.

[0055] The heartbeat communication connection is a network communication mechanism that can be used to detect and maintain the active state of the communication link. It is achieved by regularly sending and receiving specific data packets, such as heartbeat packets. The size of the data packet can be set to be small, and its purpose is to check whether the two parties of the communication are still online and can receive data. In this exemplary embodiment, when the central network node returns the registration request response information to the first network node, it can also carry the preset heartbeat period, and the first network node and the central network node can respectively start a heartbeat timer to establish a heartbeat communication connection between the first network node and the central network node. In this exemplary embodiment, the central network node can send a heartbeat packet to the first network node according to the preset heartbeat period. After receiving the heartbeat packet sent by the central network node, the first network node can return confirmation information to the central network node, indicating that the heartbeat packet sent by it has been received and everything is normal. If the first network node does not receive the heartbeat packet sent by the central network node within the preset time period, or the first network node does not return confirmation information to the central network node, or the central network node receives abnormal response information sent by the first network node, it can be considered that there is a problem with the communication link. At this time, appropriate measures can be taken, such as re-establishing the connection or notifying the network nodes, to ensure reliable data transmission.

[0056] Figure 5An interactive flow chart of network information management in this exemplary embodiment is shown. The network information management system includes a first network node, a central network node, and a second network node. The first network node is a distributed network A, which may specifically include a NF 510 of the distributed network A and a service agent 520 of the distributed network A. The central network node includes a central network service agent 530. The second network node is a distributed network B, which may specifically include a service agent 540 of the distributed network B. For example, the following steps may be specifically included:

[0057] Step S502: After the NF 510 instance of the distributed network A goes online, it registers its own configuration information with the service agent 520 of the distributed network A; wherein the own configuration information may include NF identification, NF service list, IP address, and supported service parameters, etc.;

[0058] Step S504: after determining that all planned NFs are online, the service agent 520 of the distributed network A generates the first node configuration information of the distributed network A; wherein the first node configuration information is the explicit configuration information extracted from the configuration information of the NF 510 of the distributed network A itself, that is, when generating the first node configuration information, the service agent 520 of the distributed network A needs to hide the implicit configuration information such as the NF instance identifier and the IP address, and only generates the first node configuration information according to the explicit configuration information such as the NF type and the support parameters, and sends it to the central network service agent 530;

[0059] Step S506, the service agent 520 of the distributed network A initiates a network registration request to the central network service agent 530; the network registration request is used to request network configuration registration, which may include the first node configuration information, and may also implicitly subscribe to changes in network status information of other participants, such as subscribing to changes in status information of the distributed network B and the central network, and the status information may include network online, offline, fault, etc.;

[0060] Step S508, the central network service agent 530 stores the first node configuration information of the distributed network A into the network configuration information list of the central network;

[0061] Step S510, the central network service agent 530 sends a registration request response message to the service agent 520 of the distributed network A, informing the distributed network A that the network configuration registration is successful; the registration request response message may include node configuration information of other network nodes, such as the central node configuration information of the central network and the second node configuration information of the distributed network B;

[0062] Step S512, the service agent 520 of the distributed network A stores the node configuration information of other network nodes; wherein the node configuration information of other network nodes includes the central node configuration information of the central network and the second node configuration information of the distributed network B;

[0063] Step S514, the service agent 520 of the distributed network A and the central network service agent 530 respectively start a heartbeat timing device, so that the central network can monitor the status of the distributed network A through the heartbeat mechanism, such as the status of the distributed network A being online, offline or having a fault;

[0064] Step S516, the central network sends notification information to the service agent 540 of the registered distributed network B through the central network service agent 530 to inform the distributed network B that the distributed network A has come online; wherein the notification information may include the first node configuration information of the distributed network A. In this exemplary embodiment, the notification information may also be sent to other registered distributed networks;

[0065] Step S518, the service agent 540 of the distributed network B adds the first node configuration information of the distributed network A to the network configuration information list of the distributed network B;

[0066] Step S520 , the service agent 540 of the distributed network B replies a notification response to the central network service agent 530 , informing the central network service agent 530 that the configuration information synchronization is completed.

[0067] In an exemplary embodiment, the network information management method may further include:

[0068] In response to detecting an abnormality in the heartbeat communication connection, deleting first node configuration information of the first network node from the central network configuration information;

[0069] An abnormality notification is sent to the second network node, so that the second network node deletes the first node configuration information of the first network node from the second network configuration information.

[0070] Among them, the abnormal situation of the heartbeat communication connection may include an abnormal situation of the first network node, such as the heartbeat request timeout of the first network node, the first network node offline or other faults of the first network node; the abnormal situation may also include an abnormal situation of the central network node, such as the heartbeat response timeout of the central network node or other faults of the central network node.

[0071] In this exemplary embodiment, when an abnormality is detected in the heartbeat communication connection, for example, when the heartbeat communication connection is abnormal due to the first network node, the first node configuration information of the first network node can be deleted from the central network configuration information, for example, the first node configuration information can be deleted from the network configuration information list configured on the central network node side, and an abnormality notification can be sent to the second network node to inform the second network node that an abnormality has occurred in the heartbeat communication connection between the central network node and the first network node, so that the second network node can delete the first node configuration information of the first network node in its network configuration information.

[0072] Figure 6 The interactive flow chart of a network information management method in the case of an abnormal heartbeat communication connection in this exemplary embodiment is shown. The network information management system may include a service agent 610 of a distributed network A, a central network service agent 620, and a service agent 630 of a distributed network B. Specifically, the following steps may be included:

[0073] Step S610, when the central network service agent 620 detects through the heartbeat communication connection that the heartbeat request of the service agent 610 of the distributed network A has timed out, it is determined that the service agent 610 of the distributed network A may have a fault, making the distributed network A inaccessible;

[0074] Step S620, the central network service agent 620 deletes the first node configuration information of the distributed network A in the central network configuration information list;

[0075] Step S630, the central network service agent 620 notifies the status information of the distributed network A, such as the offline message, to the service agents of other network nodes, such as the service agent 630 of the distributed network B;

[0076] Step S640 : the service agent 630 of the distributed network B deletes the first node configuration information of the distributed network A from the network configuration information list of the distributed network B.

[0077] In an exemplary embodiment, the network information management method may further include:

[0078] In response to detecting an abnormality in the heartbeat communication connection, the first network node is instructed to delete the added central node configuration information and / or the second node configuration information, and to send a network registration request to the central network node again.

[0079] In this exemplary embodiment, when an abnormality is detected in the heartbeat communication connection, for example, when the heartbeat communication connection is abnormal due to the central network node, the first network node can be made to delete the added central node configuration information and / or the second node configuration information, and send a network registration request to the central network node again, for example, the first network node is made to periodically initiate a network registration request for network configuration to the central network node again until the re-registration is successful. In addition, when the first network node deletes the added central node configuration information and / or the second node configuration information, the central network node and the second network node can also delete the first node configuration information of the first network node on this side according to actual needs, so as to achieve management synchronization of configuration information.

[0083] Step S730, the service agent 710 of the distributed network A re-initiates a network registration request for registering network configuration information to the central network service agent 720 according to a preset period until the re-registration is successful.

[0084] In an exemplary embodiment, the network information management method may further include:

[0085] In response to receiving a configuration information change request sent by the first network node, the central network node updates the central network configuration information of the central network node according to the configuration information change request, and sends the configuration information change request to the second network node, so that the second network node updates the second network configuration information of the second network node according to the configuration information change request.

[0086] In actual applications, the first network node may encounter some situations, such as capacity expansion, offline, or load changes, etc. In these situations, the first node configuration information of the first network node may change. In order to ensure the accuracy of node configuration information synchronization in the network configuration information of each network node, when the first node configuration information of the first network node changes, a configuration information change request can be sent to the central network node. The request may include the changed node configuration information and the node configuration information that needs to be changed. After receiving the configuration information change request, the central network node can update the central network configuration information. In addition, the central network node can also send the configuration information change request to the second network node to enable the second network node to update the second network configuration information according to the configuration information change request.

[0087] Figure 8 Another interactive flow chart of network information management in this exemplary embodiment is shown. The network information management system includes a first network node, a central network node, and a second network node. The first network node is a distributed network A, which may specifically include a NF 810 of the distributed network A and a service agent 820 of the distributed network A. The central network node includes a central network service agent 830. The second network node is a distributed network B, which may specifically include a service agent 840 of the distributed network B. For example, the following steps may be specifically included:

[0088] Step S810, in response to detecting that a change occurs to the NF 810 of the distributed network A, such as expansion, offline, or load change, the change information of the configuration information of the first node of the distributed network A is synchronized to the service agent 820 of the distributed network A;

[0089] Step S820, the service agent 820 of the distributed network A updates the network configuration information list of the distributed network A according to the change information of the first node configuration information;

[0090] Step S830, the service agent 820 of the distributed network A sends a configuration information change request to the central network service agent 830; wherein the configuration information change request includes the change information of the first node configuration information;

[0091] Step S840, the central network service agent 830 updates the first node configuration information of the distributed node A in the network configuration information list of the central network;

[0092] Step S850, the central network service agent 830 replies a response message of successful update to the service agent 820 of the distributed network A;

[0093] Step S860, sending the change information of the configuration information of the first node of the distributed network A to other network nodes, such as the service agent 840 of the distributed network node B, through the central network service agent 830;

[0094] Step S870, the service agent 840 of the distributed network B updates the stored first node configuration information according to the change information of the first node configuration information;

[0095] Step S880 , the service agent 840 of the distributed network B sends a notification response to the central network service agent 830 .

[0096] In an exemplary embodiment, the first network node synchronously adds the central node configuration information and / or the second node configuration information according to the registration request response information, including:

[0097] The first network node adds the central node configuration information and / or the second node configuration information to the first network configuration information of the first network node according to the registration request response information;

[0098] The above network information management method may further include:

[0099] In response to receiving a service processing request sent by the first network node, determining a target service network according to the first network configuration information; the target service network is used to provide a corresponding service for the first network node according to the service processing request;

[0100] The first network configuration information at least includes central node configuration information of the central network node and second node configuration information of the second network node.

[0101] To facilitate management and application, the first network node can also set the first network configuration information accordingly, such as the first network configuration information list, to effectively manage other node configuration information added synchronously and its own node configuration information, such as saving the received central node configuration information and the second node configuration information to the first network configuration information.

[0102] In actual applications, after going online, the first network node may initiate a service processing request to request a network service, wherein the service processing request may include relevant information for requesting service processing, such as service discovery parameters.

[0103] This exemplary embodiment can search for node configuration information in the first network configuration information configured by the first network node for node configuration information management to determine a target service network for providing network services to the first network node. The target service network can be a central network node or a second network node, etc., and the present disclosure does not make specific limitations on this.

[0104] Specifically, the first network node can first send a service processing request to its own service agent. When a suitable network node cannot be found according to the service processing request, the node configuration information can be searched in the first network configuration information. The search can be performed according to a pre-set priority. After determining the target service network, the service processing request can be sent to the target service network so that the target service network can parse the service processing request and implement a responsive network service.

[0105] In this exemplary embodiment, the target service network may be a second network node or a central network node. The second network node is used as an example below. Fig. 9 The interactive flow chart of another network information management in this exemplary embodiment is shown. The network information management system includes a first network node and a second network node, wherein the first network node is a distributed network A, and specifically may include a consumer NF 910 of the distributed network A and a service agent 920 of the distributed network A, and the second network node is a distributed network B, and specifically may include a service agent 930 of the distributed network B and a producer NF 940 of the distributed network B. Specifically, the following steps may be included:

[0106] Step S902, the distributed network A triggers a service demand according to the interactive behavior of the connected user equipment or the request of other NFs;

[0107] Step S904, the consumer NF 910 of the distributed network A directly initiates a service processing request to the service agent 920 of the distributed network A; wherein the service processing request may include service discovery parameters, such as user identification, authentication type and DNN (Data Network Name), etc.;

[0108] Step S906, when the service agent 920 of the distributed network A cannot find a suitable network node to provide services according to the discovery parameters, but can find the node configuration information of the network node that can provide services in the network configuration information list of the distributed network A, the collaborative network, such as the distributed network B, can be determined according to the priority of each network node; wherein the collaborative network is the target service network, and the priority of each network node can be determined according to information such as capacity, load and location;

[0109] Step S908, the service agent 920 of the distributed network A performs designated processing on the service processing request that requires cross-network collaboration, such as replacing the destination address of the callback URI of the consumer NF 910 of the distributed network A with the service agent address of the network to achieve topology hiding, and adding the access tokens of the requester network and network element, etc.;

[0110] Step S910, the service agent 920 of the distributed network A forwards the service processing request to the service agent 930 of the distributed network B;

[0111] Step S912, the service agent 930 of the distributed network B parses the service processing request and extracts the access token and other discovery parameters;

[0112] Step S914, the service agent 930 of the distributed network B verifies the legitimacy of the requester distributed network A and the consumer NF 910 of the distributed network A according to the access token;

[0113] Step S916, after determining that the verification is passed, the service agent 930 of the distributed network B determines a suitable producer NF of the distributed network B according to the discovery parameters; the specific determination method may be determined according to factors such as capacity and load;

[0114] Step S918, the service agent 930 of the distributed network B forwards the service processing request to the selected producer NF of the distributed network B;

[0115] Step S920, the producer NF 940 of the distributed network B parses the service processing request and replies with a service processing response; if it is detected that the service processing request includes a callback URI (Uniform Resource Identifier), it is necessary to record the instance ID (Identity document) of the consumer NF 910 of the distributed network A, which can be carried in the service processing request or discovery parameters, and is used to correctly route to the consumer when the callback operation is triggered;

[0116] Step S922, the service proxy 930 of the distributed network B replaces the destination address of the service producer URI in the response with the service proxy address to achieve topology hiding;

[0117] Step S924, the service agent 930 of the distributed network B forwards the response to the service agent 920 of the distributed network A;

[0118] Step S926 , the service agent 920 of the distributed network A finally forwards the service response to the consumer NF 910 of the distributed network A.

[0119] It should be noted that, since the service proxy replaces the destination address of the callback URI with its own address when processing the request / response of the internal NF, if the subsequent cross-network collaborative NF has continued business needs, such as secondary authentication or deregistration, it will carry the destination address of the callback URI and the instance ID of the callback NF as discovery parameters to initiate a request to the local service proxy. The local service proxy can directly redirect the request to the service proxy of the network that previously participated in the collaboration through the destination address of the callback URI, and the service proxy will then forward the request to the NF that previously participated in the collaboration through the instance ID of the callback NF, thereby achieving the correct routing forwarding of the callback request between the two cross-network NFs that previously collaborated.

[0120] Based on the above content, on the one hand, this exemplary embodiment designs a network-level configuration information service synchronization mechanism in combination with future distributed networking scenarios. The service agents of each distributed network can obtain comprehensive service configuration information of the remaining networks participating in the networking through registration, update and notification, so that cross-network collaboration is not limited to the collaboration between mobile / session management network elements and user data network elements, but can be expanded to the collaboration of 6G communication, intelligence, computing and other services, thereby improving the flexibility of cross-network collaboration. The central network can detect the abnormality of the working status of the distributed network service agent in a timely manner through the heartbeat mechanism, and promptly notify the entire network of the offline status of the distributed network, thereby improving the reliability of the networking.

[0121] Compared with the existing 5G network that only supports cross-network collaboration between mobile / session management network elements based on number segments and user data network elements, this exemplary embodiment supports cross-network collaboration of multiple types of services, and is more suitable for flexible collaboration of various networks in future 6G distributed networking scenarios; in addition, this exemplary embodiment configures a notification mechanism and a heartbeat mechanism between the central network service agent and the distributed network service agent, so that the distributed network can quickly synchronize the service configuration changes of the entire network through notifications from the central network, and make efficient network selection decisions subsequently, and the central network can monitor the operating status of the distributed network based on the heartbeat to improve the reliability of the networking.

[0122] On the other hand, in this exemplary embodiment, cross-network collaboration does not adopt the mechanism of first obtaining the NF service discovery result of the target network and then requesting the service. Instead, the service agent of this network directly initiates the NF service request to the target network service agent based on the synchronized network configuration information, and the target network service agent selects the appropriate service producer to respond based on the discovery parameters under the condition that the token verification is passed, which improves efficiency, and the service consumer cannot obtain the detailed configuration information of the collaborative network service producer; the interaction between each network is carried out through the service agent, and the cross-network request / response is topologically hidden by the service agent, and the access token is generated / verified, which improves the security of cross-network collaboration. Compared with the topology hiding scheme of SCP (Service Communications Proxy) in D mode, this exemplary embodiment can not only support cross-network NF collaboration, but also hide the callback URI and other parts that may indirectly expose the topology information of this network, thereby improving privacy. Compared with the topology hiding solution of SEPP (Security Edge Protection Proxies), this exemplary embodiment can also be applied to the NF collaboration between the distributed private network of the same PLMN and the central public network, and for the address of the callback URI, the NF address information is not hidden by rewriting the FQDN, but by replacing it with the address of the network service proxy. Therefore, it supports address hiding in both FQDN format and IP format.

Fig.10 The device 1000 may include a first information management module 1010, which is used to add the first node configuration information to the central network configuration information in response to the central network node receiving a network registration request sent by the first network node; the network registration request at least includes the first node configuration information of the first network node, and the central network configuration information at least includes the central node configuration information of the central network node and / or the second node configuration information of the second network node; a second information management module 1020, which is used to send registration request response information to the first network node through the central network node, so that the first network node synchronously adds the central node configuration information and / or the second node configuration information according to the registration request response information; the registration request response information includes the central network configuration information; a third information management module 1030, which is used to send notification information containing the first node configuration information to the second network node through the central network node in response to the first network node meeting a preset condition, so that the second network node adds the first node configuration information to the second network configuration information according to the notification information.
