Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a network information management method, a network information management device, an electronic apparatus, and a computer readable storage medium.

Background

With the rapid development of communication technology, information communication between networks is one of the key points of current attention. The existing 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) network adopts two-stage NRF (NF Repository Function, network storage function) for service management, where the provincial NRF is responsible for service registration and discovery of control plane network elements in the provincial NRF, and the backbone NRF is mainly responsible for forwarding network element discovery query and response messages across provincials. Taking fig. 1 as an example, when a service consumer in province a, such as AMF (ACCESS AND Mobility Management Function ) 110 in province a, needs to provide an initial registration/session establishment service for a user belonging to province B, a UDM (Unified DATA MANAGEMENT, unified data management function) discovery request needs to be initiated to NRF (NF Repository Function, network storage function) 120 in province to query user Subscription data, carrying a user Subscription PERMANENT IDENTITY (Subscription permanent identifier) identifier as a discovery parameter. The NRF 120 of this province finds that the user number segment does not match with the UDM of this province, then forwards the discovery request to the backbone NRF 130, the backbone NRF 130 forwards to the NRF 140 of the B province based on the number segment configuration of different provinces, the NRF 140 of the B province stores the UDM 150 registration information of this province, if including address information, the UDM 150 service configuration information of this province is returned to the backbone NRF 130 through the service discovery response, and then the backbone NRF 130 forwards to vNRF of the a province, finally the AMF of the a province acquires the UDM configuration information of the B province, then caches the discovery result and directly initiates the service request to the UDM of the B province. For UE (User Equipment) or NF (Network Function) in province B, the AMF in province a is vAMF (VISITED AMF, visited access and mobility management Function), the NRF in province a is vNRF (VISITED NRF, visited Network storage Function), the NRF in province B is hNRF (home NRF, home Network storage Function), and the UDM is hUDM (home UDM).

However, the above network information management method is limited to the discovery and request of the cross-network service of the user data network element, and cannot be applied to the application scenario of diversified cross-network cooperative service, and the interaction flow is complex, the timeliness is poor, and it is not possible to efficiently cooperate with each participating network to obtain the service information of the cooperative network more comprehensively, for example, it is not possible to apply to the 6G (6 th Generation Mobile Communication Technology, sixth generation mobile communication technology) network. Therefore, how to effectively manage the network information is a technical problem to be solved in the prior art.

It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

In the present exemplary embodiment, the node configuration information includes the number of the network, mcc+mnc+specific network identifier, network type, central network/distributed network, SCP address, IP or FQDN form (no need of exposing NRF address information because service discovery through NRF is not needed for cross-network service collaboration), location and coverage information, network capability information exposed externally as required, network function including externally exposed NF service list and supporting parameters such as number segment, DNN and user authentication mode, etc., but not including detailed privacy information such as identifier and address of each NF instance, network performance including capacity and load, etc.

The following describes the present exemplary embodiment with reference to fig. 4, and as shown in fig. 4, the network information management method may include the following steps S410 to S430:

In step S410, in response to the central network node receiving the network registration request sent by the first network node, the first node configuration information is added to the central network configuration information, wherein the network registration request at least comprises the first node configuration information of the first network node, and the central network configuration information at least comprises the central node configuration information of the central network node and/or the second node configuration information of the second network node.

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 in network management of the central network node. The network registration request refers to a request sent by the first network node for joining the central network node to perform network management, and the network registration request at least can include first node configuration information of the first network node.

In the present exemplary embodiment, the node configuration information may include a network number or identifier, for example, mcc+mnc+specific number, or a brand new numbering system, a network type, for example, a central network/distributed network, address information of a service agent, for example, an IP address or FQDN, location and coverage information, network capability information exposed to the outside as required, for example, network functions including NF service lists and supporting parameters, such as number segments, DNN, and user authentication modes, etc., but does not include privacy information, such as identification of each NF instance and address, network performance including capacity and load, etc.

The first node configuration information refers to service configuration information related to the first network node, for example, when the first network node is an NF of the distributed network, the first node configuration information may include an identification of the NF of the first network node, a service list of the NF, a type of the NF, an IP (Internet Protocol ) address, a support parameter, or the like, and the support parameter may include a database number segment, or a support parameter providing an AI (ARTIFICIAL INTELLIGENCE ) function or other 6G function.

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

In an exemplary embodiment, the first network node may include a network function NF of the first distributed network and a service proxy of the first distributed network, and the first network node sending the network registration request to the central network node may include the steps of:

After the network function instance of the first distributed network is online, the configuration information of the service agent of the first distributed network can be registered to the service agent of the first distributed network, for example, the information such as NF identification, NF service list, IP address, supported service parameters and the like is registered to the service agent of the first distributed network, and after the service agent of the first distributed network judges that all planned NF are online, the service agent of the first distributed network can generate the configuration information of the first node and initiate a network registration request to a central network node by utilizing the configuration information of the first node.

It should be noted that, in this exemplary embodiment, the configuration information includes explicit configuration information and implicit configuration information, explicit configuration information may be set up from the configuration information of the configuration information to generate the configuration information of the first node, and the configuration information of the first node is sent to the central network node, for example, after the service agent of the first distributed network determines that all planned NFs are online, the service agent may hide the implicit configuration information such as NF instance identifiers and IP addresses, and only extract explicit configuration information such as NF types and supporting parameters, so as to generate the configuration information of the first node.

Step S420, the registration request response information 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, wherein the registration request response information comprises the central network configuration information.

After receiving the network registration request containing the first node configuration information, the central network node may add the first node configuration information to the central network configuration information after the verification is successful. Registration request response information may then be returned to the first network node to inform the first network node of its registration request processing results. The registration request processing result may include central node configuration information of the central network node and/or second node configuration information of the second network node, where the central node configuration information is similar to the second node configuration information, and may include configuration information of the network node, for example, related information of NF, or supported service parameters, and the like, similar to the first node configuration information. After receiving the registration request response information, the first network node may add the central node configuration information and the second node configuration information to the node synchronously, for example, may also maintain a first network configuration information list to manage node configuration information of each network node.

Step S430, in response to the first network node meeting the preset condition, the central network node sends notification information containing the first node configuration information to the second 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.

Finally, the central network node may further send notification information including the first node configuration information to the second network node when the first network node meets a preset condition, so as to add the first node configuration information to the second network configuration information, thereby implementing information synchronization of the network configuration information in each network node. The second network configuration information may be a local network configuration information list configured by the second network node, and the notification information may include first node configuration information of the first network node, and when the second network node receives the notification information, the second network node may extract the first node configuration information from the first node configuration information and store the first node configuration information in the local second network configuration information. In addition, the notification information may also include 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.

In this exemplary embodiment, the first network node meeting the preset condition may include that the state of the first network node meets the preset condition, for example, when the state of the first network node is an on-line state, a normal connection state, or the like, notification information including configuration information of the first node is sent to the second network node.

Based on the above description, in the present exemplary embodiment, in response to a network registration request sent by a first network node being received by a central network node, first node configuration information is added to the central network configuration information, the network registration request includes at least first node configuration information of the first network node, the central network configuration information includes at least central node configuration information of the central network node and/or second node configuration information of a second network node, registration request response information 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, and in response to the first network node meeting a preset condition, notification information including 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 one hand, the present exemplary embodiment proposes a new network information management method, which is different from the prior art in that when network information interaction is performed, information synchronization is required to be implemented between a plurality of network elements or devices through complex and cumbersome interaction operations, and the present exemplary embodiment can implement synchronization of node configuration information of each network node based on a simple and convenient flow, on the other hand, when a first network node meets a preset condition, the present exemplary embodiment can timely synchronize the first node configuration information to second network configuration information, thereby implementing accurate monitoring of the first network node and effective update of node configuration information in each network node.

In an exemplary embodiment, in response to the first network node meeting the preset condition, sending, by the central network node, notification information including the first node configuration information to the second network node may include:

The central network node monitors the first network node and sends notification information containing the first node configuration information to the second network node in response to monitoring that the first network node meets a preset condition.

The central network node monitors the first network node, which may be monitoring a state of the first network node, where the state of the first network node may include that the network of the first network node is normally running on line, has a fault, or is off line, and so on. In order to ensure that network configuration information in each network node can be synchronized in time so as to effectively manage node configuration information of the multiparty network nodes, the present exemplary embodiment may monitor the first network node through the central network node, so that the central network node may send notification information including the first node configuration information to the second network node when monitoring that the first network node meets a preset condition, and execute a corresponding instruction.

Wherein the corresponding instructions may include updating the central network configuration information, for example, modifying first node configuration information of the first network node therein, or deleting first node configuration information of the first network node, and the corresponding instructions may further include sending a notification to the second network node to cause the second network node to update or delete the first node configuration information in the second network configuration information, and so on.

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

and establishing heartbeat communication connection 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.

A heartbeat communication connection is a network communication mechanism that may be used to detect and maintain the active state of a communication link. It is achieved by periodically sending and receiving specific data packets, such as heartbeat packets, which can be set to a small size in order to check whether both parties to the communication are still online and able to receive data. In this exemplary embodiment, when the central network node returns the registration request response information to the first network node, the central network node may simultaneously carry a preset heartbeat cycle, and the first network node and the central network node may 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 may send a heartbeat packet to the first network node according to a preset heartbeat cycle, and after receiving the heartbeat packet sent by the central network node, the first network node may return acknowledgement information to the central network node, which indicates that the heartbeat packet sent by the central network node has been received, and all 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 acknowledgement information to the central network node or the central network node receives response abnormal information sent by the first network node, the communication link can be considered to have a problem. At this point, corresponding measures may be taken, such as re-establishing a connection or informing the network node, to ensure reliable transmission of the data.

step S512, the service agent 520 of the distributed network A stores node configuration information of other network nodes, wherein the node configuration information of the other network nodes comprises central node configuration information of a central network and second node configuration information of the distributed network B;

Step S514, the service agent 520 and the central network service agent 530 of the distributed network a respectively start a heartbeat timing device, so that the central network can monitor the status of the distributed network a through the heartbeat mechanism, for example, the status of the distributed network a such as on-line, off-line or failure;

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 is on line, wherein the notification information may include first node configuration information of the distributed network A, and in the present exemplary embodiment, the notification information may also be sent to other registered distributed networks;

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;

In step S520, the service agent 540 of the distributed network B replies a notification response to the central network service agent 530, which has informed the central network service agent 530 that the configuration information synchronization is completed.

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

Step S610, when the central network service agent 620 detects that the heartbeat request of the service agent 610 of the distributed network a is timed out through the heartbeat communication connection, it is determined that the service agent 610 of the distributed network a may fail, so that the distributed network a cannot be accessed;

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;

Step S630, the central network service agent 620 notifies the service agents of other network nodes, such as the service agent 630 of the distributed network B, of the status information of the distributed network a, such as a downlink message;

In 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.

And in response to detecting abnormal conditions of the heartbeat communication connection, enabling the first network node to delete the added central node configuration information and/or the second node configuration information, and sending a network registration request to the central network node again.

In this exemplary embodiment, when an abnormal condition of the heartbeat communication connection is detected, for example, when the heartbeat communication connection is abnormal due to a central network node, the first network node may be caused 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 periodically initiates a network registration request of the network configuration to the central network node again until the re-registration is successful. In addition, when the first network node deletes the added configuration information of the central node and/or the configuration information of the second node, the central network node and the second network node can delete the configuration information of the first node on the local side correspondingly according to actual needs, so as to realize management synchronization of the configuration information.

Fig. 7 is an interactive flowchart of a network information management method in the case of abnormal heartbeat communication connection in the present exemplary embodiment, where the network information management system may include a service agent 710 of a distributed network a and a central network service agent 720, and may specifically include the following steps:

Step S710, detecting that the service agent 710 of the distributed network a is working properly through the heartbeat communication connection, but that the heartbeat response of the central network service agent 720 is timeout;

Step S720, the service agent 710 of the distributed network a deletes the node configuration information of the synchronized 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;

In step S730, the service agent 710 of the distributed network a initiates again a network registration request for registering network configuration information to the central network service agent 720 according to a preset period until re-registration is successful.

The central network node responds to receiving the configuration information change request sent by the first 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.

In practical applications, the first network node may have some situations, for example, capacity expansion, offline, or load change, where the configuration information of the first node of the first network node may change, so as to ensure accuracy of synchronization of node configuration information in the network configuration information of each network node, when the configuration information of the first node of the first network node changes, a configuration information change request may be sent to the central network node, where the request may include changed node configuration information, or node configuration information that needs to be changed, and the central network node may update the central network configuration information after receiving the configuration information change request. In addition, the central network node may send a configuration information change request to the second network node, so that the second network node updates the second network configuration information according to the configuration information change request.

Fig. 8 shows another interaction flow chart of network information management in the present exemplary embodiment, where the network information management system includes a first network node, a central network node and a second network node, where the first network node is taken as a distributed network a, and may specifically include NF 810 of the distributed network a and service agent 820 of the distributed network a, the central network node includes central network service agent 830, and the second network node is taken as a distributed network B, and may specifically include service agent 840 of the distributed network B for illustration, and may specifically include the following steps:

Step S810, in response to detecting that the NF 810 of the distributed network a is changed, for example, capacity expansion, offline or load change, the change information of the first node configuration information of the distributed network a is synchronized to the service agent 820 of the distributed network a;

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;

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 comprises change information of the configuration information of the first node;

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;

Step S850, the central network service agent 830 replies the service agent 820 of the distributed network a with a response message of successful update;

step S860, transmitting the change information of the first node configuration information 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;

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;

in step S880, the service agent 840 of the distributed network B replies with a notification response to the central network service agent 830.

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:

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;

the network information management method may further include:

the target service network is used for providing corresponding service for the first network node according to the service processing request;

the first network configuration information at least comprises center node configuration information of the center network node and second node configuration information of the second network node.

For convenience in management and application, the first network node may also correspondingly set first network configuration information, for example, a first network configuration information list, so as to effectively manage other node configuration information added synchronously and node configuration information of the first network node, for example, store the received central node configuration information and the second node configuration information into the first network configuration information.

In practical applications, a service processing request may be initiated after the first network node is online to request a network service, where the service processing request may include relevant information for requesting service processing, such as a service discovery parameter, etc.

The present exemplary embodiment may search the node configuration information in the first network configuration information configured by the first network node for performing node configuration information management to determine a target service network for providing network services for the first network node, where the target service network may be a central network node, a second network node, or the like, and the disclosure is not limited in detail.

Specifically, the first network node may send a service processing request to its own service proxy, and when a suitable network node cannot be found according to the service processing request, the first network node may search for node configuration information in the first network configuration information, where the searching may be performed according to a preset priority, and after determining the target service network, the service processing request may be sent to the target service network, so as to implement a responsive network service by analyzing the service processing request by the target service network.

In this exemplary embodiment, the target service network may be a second network node or a central network node, and the second network node is hereinafter illustrated by way of example, fig. 9 shows an interaction flow chart of still another network information management in this exemplary embodiment, where the network information management system includes a first network node and a second network node, where the first network node is a distributed network a, and may specifically 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 may specifically include a service agent 930 of the distributed network B and a producer NF 940 of the distributed network B, and may specifically include the following steps:

Step S902, the distributed network A triggers the service requirement according to the interactive behavior of the accessed user equipment or other NF requests;

step S904, the consumer NF 910 of the distributed network a directly initiates a service processing request to the service proxy 920 of the distributed network a, where the service processing request may include service discovery parameters such as a user identifier, an authentication type, DNN (Data Network Name, a data network name), etc.;

Step S906, when the service agent 920 of the distributed network A can not find a suitable network node to provide service according to the discovery parameter, but can find the node configuration information of the network node capable of providing service in the network configuration information list of the distributed network A, the cooperative network, such as the distributed network B, can be determined according to the priority of each network node, wherein the cooperative network is the target service network, and the priority of each network node can be determined according to the information of capacity, load, position and the like;

Step S908, the service agent 920 of the distributed network a performs specified processing on the service processing request that needs cross-network collaboration, for example, replaces the destination address of the callback URI of the consumer NF 910 of the distributed network a with the service agent address of the present network to implement topology hiding, and adds access tokens of the requester network and the network element, etc.;

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;

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

step S914, the service agent 930 of the distributed network B verifies the validity of the requester distributed network a and the consumer NF 910 of the distributed network a according to the access token;

Step S916, after determining that the verification is passed, the service agent 930 of the distributed network B determines a proper producer NF of the distributed network B according to the discovery parameters;

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;

If it is detected that the service processing request includes a callback URI (Uniform Resource Identifier ), then the consumer NF 910 instance ID (Identity document, unique identification) of the distributed network A needs to be recorded, which instance ID can be carried in the service processing request or discovery parameters for correct routing to the consumer when triggering callback operations;

Step S922, the service agent 930 of the distributed network B replaces the destination address related to the URI of the service producer in the response with the service agent address to implement topology hiding;

Step S924, the service proxy 930 of the distributed network B forwards the response to the service proxy 920 of the distributed network a;

in step S926, the service proxy 920 of the distributed network a finally forwards the service response to the consumer NF 910 of the distributed network a.

It should be noted that, when the service agent processes the request/response of the internal NF, the destination address of the callback URI is replaced with the address of the service agent, so if the subsequent NF in cross-network collaboration has a continuous service requirement, for example, such as secondary authentication or deregistration, the service agent initiates a request to the local service agent with the destination address of the callback URI and the instance ID of the callback NF as discovery parameters. The local service agent can redirect the request to the service agent of the network previously participating in the cooperation directly through the destination address of the callback URI, and the service agent forwards the request to the NF previously participating in the cooperation through the instance ID of the callback NF, so that the callback request is forwarded in a correct route between the two cross-network NFs previously participating in the cooperation.

Based on the above, on the one hand, the present exemplary embodiment designs a network-level configuration information service synchronization mechanism in combination with the future distributed networking scenario, and the service agents of each distributed network may obtain the overall service configuration information of the networks participating in networking through registration, update and notification, so that the cross-network collaboration is not limited to the collaboration of the mobile/session management network element and the user data network element, but can extend to the collaboration of multiple services such as 6G communication, intelligence, calculation, and the like, and improves the flexibility of the cross-network collaboration. The central network can timely detect the abnormality of the working state of the distributed network service agent through a heartbeat mechanism, timely notify the whole network of the downlink state of the distributed network, and improve the networking reliability.

In addition, the present 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 synchronize the whole network service configuration change rapidly through the notification of the central network, and make network selection decisions in high efficiency later, and the central network can monitor the running state of the distributed network according to the heartbeat, thereby improving the reliability of the networking.

On the other hand, in the present exemplary embodiment, the cross-network collaboration does not adopt a mechanism of acquiring the NF service discovery result of the target network and then requesting the service, but directly initiates the NF service request to the target network service proxy by the service proxy of the present network according to the synchronized network configuration information, and the target network service proxy selects an appropriate service producer to answer according to the discovery parameter under the condition that token verification passes, thereby improving efficiency, and the service consumer cannot acquire the detailed configuration information of the collaborative network service producer. Compared with the topology hiding scheme in the D mode of the SCP (Service Communications Proxy, service communication proxy), the embodiment can support cross-network NF collaboration, hide parts of callback URI and the like which possibly indirectly expose the network topology information, and improve privacy. Compared with the topology hiding scheme of SEPP (Security Edge Protection Proxies, secure edge protection proxy), the present exemplary embodiment may also be applied to NF collaboration between a distributed private network and a central public network of the same PLMN, and hide NF address information in a manner of not using FQDN for callback URI address, but hide NF address information by replacing it with the present network service proxy address, thus supporting both FQDN format and IP format address hiding.
