Description
Technical Field
The invention belongs to the technical field of 5G communication, and particularly relates to a method and a system for monitoring the health condition of a network element of a 5G core network and the network element.
Background
The mobile communication technology is developed from the first generation to the fifth generation, and the speed is higher and the time delay is lower. In a 5G complex Network, a core Network adopts a Service Based Architecture (SBA), refers to a "micro-Service" concept in the Information Technology (IT) field, and splits a physical entity having a plurality of functions into a plurality of logical Network element functions (NF) having individual functions, and each individual implements ITs own Service Function. The 5G core network element mainly comprises:
(1) AMF (Access and Mobility Management Function) network element functions include: connection management, reachability management, mobility management, access authorization, etc.
(2) The 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.
(3) The network element functions of the UPF (User plane Function) include: session points at which the external PDUs are interconnected with the data network, packet routing and forwarding (e.g., instances that support an uplink classifier to route traffic flows to the data network), and so forth.
(4) PCF (Policy Control Function) network element functions include: supporting a unified policy framework, providing policy rules, accessing subscription information related to policy decisions in a unified data store.
(5) The NEF (Network Exposure Function) Network element functions include: NEF stores/retrieves information as structured data using a standardized interface (nurr) to UDR (unified data repository).
(6) NRF (Network Repository Function) Network element functions include: and maintaining the available network element instances and the network element configuration files supporting the services. The NRF gives a processing result, such as retaining a network element, deleting a network element, issuing an alarm, and the like, by analyzing the heartbeat packet sent by each network element.
(7) UDM (Unified Data Management) network element functions include: generating 3GPP secret key authentication information, user identification processing, network element registration management, legal interception function, subscription management, subscription data management and storage, authentication data and the like.
(8) The network element functions of the AUSF (Authentication Server Function) include: terminal authentication, providing key materials, protecting control information lists, and the like.
(9) NSSF (Network Slice Selection Function) Network element functions include: selecting a network slice to serve the UE, determining a set of AMFs to use for serving the UE, determining a list of candidate AMFs from the configuration, and so on.
The decoupling and integration among the network elements are realized through modularization, and the decoupled network elements can be independently expanded, independently evolved and deployed as required. Thus, many NFs in a 5G core network require unified management and maintenance.
Disclosure of Invention
Although the 3GPP specification R15 specifies that the network repository function NRF is responsible for managing each network element, the 3GPP does not give how the NRF monitors the core network elements, and particularly how the NRF monitors the health status of each network element.
The 5G service architecture transforms a logical network element formed by binding traditional hardware and software to network element virtualization (nfv). The number of the network elements is increased, and the health state of the network elements needs to be regularly monitored so as to timely discover, warn and predict the network element abnormity and ensure the high-speed operation of the 5G network. NRF network elements in the 5G core network take on management functions of network elements in the core network, such as AMF (access and mobility management function), SMF (session management function), NEF (network open function), and the like. And the network elements such as the AMF, the SMF, the NEF and the like report heartbeat information packets to the NRF periodically to show the survival condition of the network element. However, the heartbeat packet includes only information such as a heartbeat number. In addition, the NRF queries the health status information of each network element in a subscription manner, but the NRF cannot necessarily acquire the health status information in time. These make it difficult for NRF to manage many network elements efficiently and reliably.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for monitoring the health of network elements in a 5G core network, which can monitor the health of each network element more efficiently, and can monitor the health of each network element while affecting the performance of the network element as low as possible and reducing the data traffic as low as possible.

Fig. 1 is a block diagram illustrating a monitoring system 1 according to an embodiment of the present invention.
The monitoring system 1 is a system for health monitoring for a 5G core network element. The monitoring system 1 comprises a network repository functional network element NRF11 and at least one other network element different from the network repository functional network element NRF 11. In the embodiment shown in fig. 1, the at least one other network element illustrates an access and mobility management function network element AMF 12, a session management function network element SMF 13, a user plane function network element UPF 14, a network open function network element NEF15, a policy control function network element PCF 16. These network elements are all illustrations, which may be any 5G core network element.
The network repository function network element NRF11 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 NEF15, and the policy control function network element PCF16 are respectively configured to include a network element reporting component 30. The network element monitoring component 20 is communicably connected to the network element reporting component 30 of each network element via the 5G network.
In the following, the access and mobility management function network element AMF 12 is described as an example with respect to at least one other network element, but it should be understood that the following description may also apply to other network elements.
The network element monitoring component 20 is configured to receive the health information periodically sent by the network element reporting component 30 of each network element at heartbeat intervals, and determine whether the network element is abnormal according to the received health information and/or the heartbeat intervals of the network element reporting component 30. In this embodiment, the network element monitoring component 20 receives the health information periodically 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. The health information is information data reflecting the health condition of the network element. In one embodiment, the health information includes more than 1 content item, and the content item includes at least one of CPU temperature, CPU utilization, physical memory utilization, hard disk read-write data traffic, network access traffic, and the like of each network element. In one embodiment, the network element monitoring component 20 determines that an anomaly has occurred in the network element in the event that one or several of the received content items of health information exceed respective prescribed thresholds. In another embodiment, the network element monitoring component 20 determines that an anomaly has occurred in the network element if the received heartbeat interval is not within a specified range.
When the network element monitoring component 20 determines 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 for the access and mobility management function network element AMF 12, and after receiving the component configuration information, the network element reporting component 30 of the access and mobility management function network element AMF 12 configures itself according to the component configuration information to change the content item 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 an embodiment, when it is determined that the access and mobility management function network element AMF 12 is normal, the network repository function network element NRF11 records the network element health information, updates the network element health log, and continues to receive the health information periodically sent at the heartbeat interval by the network element reporting component 30 of each network element.
The network element monitoring component 20 is further configured to receive the health information sent by the network element reporting component 30 after the component configuration information is changed and configured, determine whether the access and mobility management function network element AMF 12 is abnormal according to the received health information and/or the heartbeat interval, report that the access and mobility management function network element AMF 12 is abnormal if the access and mobility management function network element AMF 12 is determined to be abnormal, and continue to receive the health information periodically sent by the network element reporting component 30 of the access and mobility management function network element AMF 12 if the access and mobility management function network element AMF 12 is determined to be normal.
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, 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 item 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.
In one embodiment, when the network repository function network element NRF11 finds that a new network element is accessed to the 5G core network, the element configuration information may be sent by the network element monitoring component 20 to the network element reporting component 30 of the network element. In another embodiment, when the network repository function NRF11 finds that a new network element is accessed to the 5G core network, the network element monitoring component 20 may also not send the 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 send the health information periodically with a default configuration.
In one embodiment, the component configuration information sent by the network element monitoring component 20 for 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 is configured such that a heartbeat interval for reporting health information by the access and mobility management function network element AMF 12 is shortened and/or a content item of health information sent by the access and mobility management function network element AMF 12 is increased. By shortening the heartbeat interval of reporting the health information, the content items and the change trend of the health information of the access and mobility management function network element AMF 12 can be monitored more timely and rapidly. By adding the content items of the health information, the respective health parameters of the access and mobility management function network element AMF 12 can be monitored more comprehensively.
Both the network repository function network element NRF11 and the network element monitoring component 20 may be implemented in hardware, firmware, software, and combinations thereof. In one embodiment, the network repository functional network element NRF11 comprises one or more processors and a memory having stored thereon computer-executable instructions which, when executed by the one or more processors, cause the one or more processors to implement the functions of the network repository functional network element NRF 11.
The access and mobility management function network elements, such as the network element AMF 12, and the network element reporting component 30 may be implemented by hardware, firmware, software, or a combination thereof. In one embodiment, the access and mobility management function network element AMF 12 comprises one or more processors and a memory storing computer executable instructions which, when executed by the one or more processors, cause the one or more processors to implement the functions of the access and mobility management function network element AMF 12.
Figure 2 is a flow diagram illustrating a network element monitoring component according to an embodiment of the present invention.
As shown in fig. 2, in step S202, the network element monitoring component 20 of the network repository function network element NRF11 receives the health information periodically sent by the network element reporting component 30 of the access and mobility management function network element AMF 12 at heartbeat intervals. In one embodiment, the content item of the health information includes at least one of a CPU temperature, a CPU usage rate, a physical memory usage rate, a hard disk read-write data traffic, and a network ingress-egress traffic of the access and mobility management function network element AMF 12.
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. If 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, for the access and mobility management function network element AMF 12, component configuration information of the network element reporting component 30, where the component configuration information is used for the network element reporting component 30 to configure itself according to the received component configuration information so as to change a content item of the reported health information and/or a heartbeat interval of the network element reporting component 30. In one embodiment, the component configuration information sent by the network element monitoring component 20 for the access and mobility management function network element AMF 12 when it is determined that an abnormality occurs in the access and mobility management function network element AMF 12 is configured to shorten a heartbeat interval of the health information reported by the access and mobility management function network element AMF 12 and/or increase a content item of the health information sent by the access and mobility management function network element AMF 12. By shortening the heartbeat interval of reporting the health information, the content items and the change trend of the health information of the access and mobility management function network element AMF 12 can be monitored more timely and rapidly. By adding the content items of the health information, the respective health parameters of the access and mobility management function network element AMF 12 can be monitored more comprehensively.
In one embodiment, in case it is determined that the access and mobility management function network element AMF 12 is normal (i.e. "no" in step S204), the network element monitoring component 20 records the network element health information and updates the network element health log in step S214. Thereafter, the process returns to step S202.
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 being configured by change according to the component configuration information.
Next, in step S210 the element monitoring component 20 determines whether the access and mobility management function element AMF 12 is abnormal or not, based on the health information and/or the heartbeat interval received in step S208. If the access and mobility management function element AMF 12 is determined to be abnormal (yes in step S210), the network repository function element NRF11 reports the occurrence of the abnormality of the access and mobility management function element AMF 12 to the 5G core network management element (step S212), records the health information, and updates the health log (step S214); in case that it is determined that the access and mobility management function network element AMF 12 is normal (no in step S210), returning to step S202, the network element monitoring component 20 continues to receive the health information periodically sent by the network element reporting component 30. Here, the 5G core network management network is a management layer of the entire 5G core network, and can manage and control each network element. In one embodiment, the 5G core network management network element is configured to perform basic maintenance on each network element, so as to meet basic normal maintenance requirements.
Figure 3 is a flow diagram illustrating a network element monitoring component according to another embodiment of the present invention.
In the embodiment shown in fig. 3, step S200 is added before step S202 as compared with fig. 2. The same or similar reference numerals are attached to the same or similar portions as those in fig. 2, and the description thereof is omitted.
When the network element NRF11 of the network storage function finds that a new network element is accessed 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, and performs initial configuration on the network element reporting component 30 of the network element. Thus, the health information can be sent by the uniform configuration item network element monitoring component 20 when the network element newly accesses the 5G network. In another embodiment, when the network repository function NRF11 finds that a new network element is accessed to the 5G core network, the network element monitoring component 20 may also not send the 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 send the health information periodically with the default configuration.
Figure 4 is a flow diagram illustrating a network element reporting component in accordance with one embodiment of the present invention.
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 issued by the network element monitoring component 20 of the network repository function network element NRF11, where the component configuration information is used for the network element reporting component 30 to configure itself according to the received component configuration information so as to change the content item 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 item of the health information includes at least one of CPU temperature, CPU utilization, physical memory utilization, hard disk read-write data traffic, network ingress and egress traffic of the access and mobility management function network element AMF 12
Next, in step S402, the element reporting component 30 generates health information of at least one other element according to the received component configuration information. In one embodiment, the network element reporting component 30 generates the content item in the health information according to the content item in the component configuration information and adds a timestamp to generate new network element health information.
Next, in step S404, the element reporting component 30 periodically sends the health information to the element monitoring component 20 at the heartbeat interval in the component configuration information.
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 the new component configuration information is received (i.e., "yes" in step S406), it configures itself according to the received new component configuration information. In an 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 issued by the network element monitoring component 20 of the network repository function network element NRF 11.
Next, the element reporting component 30 generates new element health information with the new element configuration information in step S408, and sends it to the element monitoring component 20 periodically in the following step S410.
According to the embodiment of the invention, the management function of the network repository functional network element is enhanced and expanded, the heartbeat information and the health information of each network element are combined, and the network element monitoring component and the network element reporting component are respectively arranged in the network repository functional network element and other network elements in the 5G core network, so that the health information of each network element can be monitored more efficiently, and the health condition of each network element is monitored on the premise of influencing the network element performance as low as possible and reducing the data traffic as low as possible.
