Description

Technical Field

[0001] The present invention belongs to the field of 5G communication technology, and in particular, relates to a method, system and network element for monitoring the health status of a 5G core network element. Background Art

[0002] Mobile communication technology has developed from the first generation to the fifth generation, with faster speeds and lower latency. In the complex 5G network, the core network adopts a service-based architecture (SBA), referring to the concept of "microservices" in the field of information technology (IT), splitting the physical entities with multiple functions into multiple logical network functions (NF) with independent functions, and each individual realizes its own service function. The 5G core network network elements mainly include:

[0003] (1) AMF (Access and Mobility Management Function) network element functions include: connection management, reachability management, mobility management, access authorization, etc.

[0004] (2) SMF (Session Management Function) Network element functions include: session management, such as session establishment, modification and release, including channel maintenance between UPF and AN nodes, etc.

[0005] (3) UPF (User plane function) network element functions include: session point for interconnection between external PDU and data network, packet routing and forwarding (for example, supporting uplink classifier to route service flow to data network instance), etc.

[0006] (4) PCF (Policy Control Function) network element functions include: supporting a unified policy framework, providing policy rules, and accessing subscription information related to policy decisions in a unified data repository.

[0007] (5) NEF (Network Exposure Function) network element functions include: NEF uses a standardized interface (Nudr) to UDR (Unified Data Repository) to store / retrieve information as structured data.

[0008] (6) NRF (Network Repository Function) Network element functions include: maintaining available network element instances and network element configuration files for their supported services. NRF analyzes the heartbeat packets sent by each network element and gives processing results, such as retaining the network element, deleting the network element, and issuing an alarm.

[0009] (7) UDM (Unified Data Management) network element functions include: generating 3GPP key authentication information, user identification processing, network element registration management, legal interception function, subscription management, management and storage of contract data, authentication data, etc.

[0010] (8)AUSF (Authentication Server Function) network element functions include: terminal authentication, provision of key materials, protection of control information list, etc.

[0011] (9) NSSF (Network Slice Selection Function) network element functions include: selecting the network slice to serve the UE, determining the AMF set to be used to serve the UE, determining the list of candidate AMFs based on the configuration, etc.

[0012] Through modularization, decoupling and integration between network elements are achieved. The decoupled network elements can be expanded, evolved, and deployed on demand independently. Therefore, the numerous NFs in the 5G core network require unified management and maintenance. Summary of the invention

[0013] Although the 3GPP specification R15 stipulates that the network repository function NRF is responsible for managing each network element, 3GPP does not specify how NRF monitors the core network elements, especially how to monitor the health status of each network element.

[0014] The 5G service-oriented architecture transforms the logical network elements formed by the traditional hardware and software bundling to the network element virtualization NFV (Network Function Virtualization). With the increase in the number of network elements, it is necessary to regularly monitor the health status of network elements in order to timely discover, warn and predict network element anomalies to ensure the high-speed operation of the 5G network. The NRF network element in the 5G core network assumes the management function of network elements such as AMF (access and mobility management function), SMF (session management function), and NEF (network open function) in the core network. Network elements such as AMF, SMF, and NEF regularly report heartbeat information packets to NRF to indicate the survival status of the network element. However, the heartbeat information packet only contains information such as the heartbeat sequence number. In addition, NRF queries the health status information of each network element by subscription, but NRF may not be able to obtain this health status information in time. All these make it difficult for NRF to effectively and reliably manage many network elements.

[0015] The present invention is proposed in view of the above problems, and its purpose is to provide a method for monitoring the health status of 5G core network network elements, so as to monitor the health status of each network element more efficiently, and monitor the health status of each network element under the premise of minimizing the impact on network element performance and reducing data traffic as much as possible.

[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] Figure 1 is a block diagram showing a monitoring system 1 according to an embodiment of the present invention.

[0033] The monitoring system 1 is a system for performing health monitoring on network elements of a 5G core network. The monitoring system 1 includes a network repository function network element NRF 11 and at least one other network element different from the network repository function network element NRF 11. Figure 1 In the illustrated embodiment, at least one other network element exemplifies access and mobility management function network element AMF 12, session management function network element SMF 13, user plane function network element UPF 14, network open function network element NEF 15, and policy control function network element PCF 16. These network elements are all examples and can be any 5G core network element.

[0034] The network repository function network element NRF 11 is configured to include a network element monitoring component 20. The access and mobility management function network element AMF 12, the session management function network element SMF 13, the user plane function network element UPF 14, the network open function network element NEF 15, and the policy control function network element PCF 16 are respectively configured to include a network element reporting component 30. The network element monitoring component 20 is communicatively connected to the network element reporting component 30 of each network element via the 5G network.

[0035] In the following, regarding at least one other network element, the access and mobility management function network element AMF 12 is taken as an example for explanation, but it should be understood that the following explanation can also be applied to other network elements.

[0036] The network element monitoring component 20 is configured to receive health information regularly sent by the network element reporting component 30 of each network element at a heartbeat interval, and determine whether the network element is abnormal according to the received health information and / or the heartbeat interval of the network element reporting component 30. In this embodiment, the network element monitoring component 20 receives health information regularly sent by the network element reporting component 30 of the access and mobility management function network element AMF 12 at a heartbeat interval, and determines whether the network element is abnormal according to the received health information and / or the heartbeat interval of the network element reporting component 30. Health information is information data reflecting the health status of the network element. In one embodiment, the health information includes more than one content item, and the content item includes at least one of the CPU temperature, CPU usage, physical memory usage, hard disk read and write data flow, network in and out flow, etc. of each network element. In one embodiment, the network element monitoring component 20 determines that the network element is abnormal when one or more items of the content items of the received health information exceed the respective specified thresholds. In another embodiment, the network element monitoring component 20 determines that the network element is abnormal when the received heartbeat interval is not within the specified range.

[0037] In the case where it is determined that the access and mobility management function network element AMF 12 is abnormal, the network element monitoring component 20 sends the component configuration information of the network element reporting component 30 to the access and mobility management function network element AMF 12. After receiving the component configuration information, the network element reporting component 30 of the access and mobility management function network element AMF 12 will configure itself according to the component configuration information to change the content items of the health information reported to the network element monitoring component 20 and / or the heartbeat interval of the network element reporting component 30. In one embodiment, in the case where it is determined that the access and mobility management function network element AMF 12 is normal, the network repository function network element NRF 11 records the network element health information, updates the network element health log, and continues to receive the health information regularly sent by the network element reporting component 30 of each network element at a heartbeat interval.

[0038] The network element monitoring component 20 is also configured to receive health information sent by the network element reporting component 30 after the component configuration information is changed, determine whether the access and mobility management function network element AMF 12 is abnormal based on the received health information and / or the heartbeat interval, and report the abnormality of the access and mobility management function network element AMF 12 when it is determined that the access and mobility management function network element AMF 12 is abnormal; and continue to receive health information regularly sent by the network element reporting component 30 of the access and mobility management function network element AMF 12 when it is determined that the access and mobility management function network element AMF 12 is normal.

[0039] The network element reporting component 30 of the access and mobility management function network element AMF 12 periodically sends the health information of the access and mobility management function network element AMF 12 to the network element monitoring component 20 at a heartbeat interval, and receives the component configuration information issued by the network element monitoring component 20, and configures itself according to the received component configuration information to change the content items of the reported health information and / or the heartbeat interval of the network element reporting component 30 of the access and mobility management function network element AMF 12.

[0040] In one embodiment, when the network repository function network element NRF 11 finds that a new network element is connected to the 5G core network, the network element monitoring component 20 may send component configuration information to the network element reporting component 30 of the network element. In another embodiment, when the network repository function network element NRF 11 finds that a new network element is connected to the 5G core network, the network element monitoring component 20 may not send component configuration information to the network element reporting component 30 of the network element, and the network element reporting component 30 of the network element may periodically send health information with a default configuration.

[0041] In one embodiment, when it is determined that the access and mobility management function network element AMF 12 is abnormal, the network element monitoring component 20 is configured for the component configuration information sent by the access and mobility management function network element AMF 12 to shorten the heartbeat interval for reporting health information of the access and mobility management function network element AMF 12 and / or increase the content items of the health information sent by the access and mobility management function network element AMF 12. By shortening the heartbeat interval for reporting health information, the various content items of the health information of the access and mobility management function network element AMF 12 and their changing trends can be monitored more timely and quickly. By increasing the content items of health information, the various health parameters of the access and mobility management function network element AMF 12 can be monitored more comprehensively.

[0042] The network repository function network element NRF 11 and the network element monitoring component 20 can be implemented by hardware, firmware, software and a combination thereof. In one embodiment, the network repository function network element NRF 11 includes one or more processors and a memory, and computer executable instructions are stored on the memory. When the computer executable instructions are executed by the one or more processors, the one or more processors implement the functions of the network repository function network element NRF 11.

[0043] The network elements such as the access and mobility management function network element AMF 12 and the network element reporting component 30 can be implemented by hardware, firmware, software and a combination thereof. In one embodiment, the access and mobility management function network element AMF 12 includes one or more processors and a memory, wherein the memory stores computer executable instructions, which, when executed by one or more processors, enable the one or more processors to implement the functions of the access and mobility management function network element AMF 12.

[0044] Figure 2 is a flow chart illustrating a network element monitoring component according to an embodiment of the present invention.

[0045] like Figure 2 As shown, in step S202, the network element monitoring component 20 of the network repository function network element NRF 11 receives health information regularly sent at heartbeat intervals by the network element reporting component 30 of the access and mobility management function network element AMF 12. In one embodiment, the content items of the health information include at least one of the CPU temperature of the access and mobility management function network element AMF 12, the CPU utilization rate, the physical memory utilization rate, the hard disk read and write data traffic, and the network in and out traffic.

[0046] In step S204, the network element monitoring component 20 determines whether the access and mobility management function network element AMF 12 is abnormal according to the received health information and / or the heartbeat interval of the network element reporting component 30. In the case where it is determined that the access and mobility management function network element AMF 12 is abnormal (i.e., "yes" in step S204), in step S206, the network element monitoring component 20 sends the component configuration information of the network element reporting component 30 to the access and mobility management function network element AMF 12, and the component configuration information is used by the network element reporting component 30 to configure itself according to the received component configuration information to change the content items of the reported health information and / or the heartbeat interval of the network element reporting component 30. In one embodiment, when it is determined that an abnormality has occurred in the access and mobility management function network element AMF 12, the network element monitoring component 20 is configured to send component configuration information for the access and mobility management function network element AMF 12 so as to shorten the heartbeat interval for reporting health information of the access and mobility management function network element AMF 12 and / or increase the content items of the health information sent by the access and mobility management function network element AMF 12. By shortening the heartbeat interval for reporting health information, the content items of the health information of the access and mobility management function network element AMF 12 and their changing trends can be monitored more timely and quickly. By increasing the content items of the health information, the various health parameters of the access and mobility management function network element AMF 12 can be monitored more comprehensively.

[0047] In one embodiment, when it is determined that the access and mobility management function network element AMF 12 is normal (ie, "No" in step S204), in step S214, the network element monitoring component 20 records the network element health information and updates the network element health log, and then returns to step S202.

[0048] After step S206, in step S208, the network element monitoring component 20 receives the health information sent by the network element reporting component 30 after the component configuration information is changed.

[0049] Next, in step S210, the network element monitoring component 20 determines whether the access and mobility management function network element AMF 12 is abnormal according to the health information and / or heartbeat interval received in step S208. In the case where the access and mobility management function network element AMF 12 is judged to be abnormal ("Yes" in step S210), the network repository function network element NRF 11 reports the abnormality of the access and mobility management function network element AMF 12 to the 5G core network network management network element (step S212), and records the health information and updates the health log (step S214); in the case where the access and mobility management function network element AMF 12 is judged to be normal ("No" in step S210), the process returns to step S202, and the network element monitoring component 20 continues to receive the health information regularly sent by the network element reporting component 30. Here, the 5G core network network management network is the management layer of the entire 5G core network, which can manage and control each network element. In one embodiment, the 5G core network network management network element is used to perform basic maintenance on each network element to meet basic and normal maintenance needs.

[0050] Figure 3 is a flow chart showing a network element monitoring component according to another embodiment of the present invention.

[0051] exist Figure 3 In the embodiment shown, Figure 2 Compared with step S202, step S200 is added before step S202. Figure 2 The same or similar parts are denoted by the same or similar reference numerals, and description thereof is omitted.

[0052] When the network repository function network element NRF 11 finds that a new network element is connected to the 5G core network, the network element monitoring component 20 sends component configuration information to the network element reporting component 30 of the network element in step S200 to perform initial configuration of the network element reporting component 30 of the network element. As a result, when a network element is newly connected to the 5G network, the network element monitoring component 20 can send health information with a unified configuration item. In another embodiment, when the network repository function network element NRF 11 finds that a new network element is connected to the 5G core network, the network element monitoring component 20 may not send component configuration information to the network element reporting component 30 of the network element, but the network element reporting component 30 of the network element may send health information regularly with a default configuration.

[0053] Figure 4 is a flow chart showing a network element reporting component according to an embodiment of the present invention.

[0054] In step S400, the network element reporting component 30 of the access and mobility management function network element AMF 12 receives the component configuration information sent by the network element monitoring component 20 of the network repository function network element NRF 11, where the component configuration information is used by the network element reporting component 30 to configure itself according to the received component configuration information to change the content items of the health information reported to the network element monitoring component 20 and / or the heartbeat interval of the network element reporting component 30. In one embodiment, the content items of the health information include at least one of the CPU temperature, CPU usage, physical memory usage, hard disk read and write data traffic, and network inbound and outbound traffic of the access and mobility management function network element AMF 12.

[0055] Next, in step S402, the network element reporting component 30 generates health information of at least one other network element according to the received component configuration information. In one embodiment, the network element reporting component 30 generates content items in the health information according to content items in the component configuration information and adds a timestamp to generate new network element health information.

[0056] Next, in step S404, the network element reporting component 30 periodically sends health information to the network element monitoring component 20 at the heartbeat interval in the component configuration information.

[0057] Next, in step S406, the network element reporting component 30 determines whether new component configuration information sent by the network element monitoring component 20 is received. When the network element reporting component 30 determines that new component configuration information is received (i.e., "yes" in step S406), it configures itself according to the received new component configuration information. In one embodiment, when the network element reporting component 30 determines that no new component configuration information is received (i.e., "no" in step S406), it returns to step S400, and the network element reporting component 30 continues to receive the component configuration information sent by the network element monitoring component 20 of the network repository function network element NRF11.

[0058] Next, in step S408 , the network element reporting component 30 generates new network element health information with the new component configuration information, and sends it to the network element monitoring component 20 regularly in the subsequent step S410 .

[0059] According to an embodiment of the present invention, the management function of the network repository functional network element is enhanced and expanded, and the heartbeat information and health information of each network element are combined. By respectively setting a network element monitoring component and a network element reporting component in the network repository functional network element and other network elements in the 5G core network, the health information of each network element can be monitored more efficiently, and the health status of each network element can be monitored under the premise of minimizing the impact on the network element performance and reducing the data traffic as much as possible.
