In the foregoing operating environment, the present application provides a resource scheduling method of a core network as shown in fig. 2. Fig. 2 is a flowchart of a resource scheduling method of a core network according to an embodiment of the present application. As shown in fig. 2, the method may include the steps of:

step S202, detecting the working states of a plurality of network elements included in the core network, wherein the plurality of network elements are deployed in the container cluster, and different network elements are used for providing different functions of the core network.

The multiple network elements in the above steps may be devices in a core network that provide network services to the outside, and in this application, a 5G core network is taken as an example for description, and the multiple network elements may be AMF, SMF, UPF, and UDM, but not limited thereto, and may also be other network elements of the 5G core network, and the multiple network elements need to be matched with each other to provide complete 5G core network services to users.

The container cluster in the above steps may be a cluster constructed by using a containerization deployment technology, and in this application, a kubernets cluster is taken as an example for description, and a plurality of network elements of a core network may be deployed in the same kubernets cluster, for example, different network elements may be deployed on different nodes, but the present invention is not limited thereto.

The operating status in the above steps may be various statuses during the operation of the network element, including but not limited to: the operating status, e.g. whether the network element is operating normally, and the load status, i.e. the resource utilization, e.g. whether the resource utilization of the network element is sufficient, meets the service requirements. In order to meet the requirement in the practical application of the 5G core network, resource regulation and control in different modes can be performed for different states of different network elements, and the working state here may not be only a certain state, but also cover various states of the network elements.

In an alternative embodiment, in order to implement a unified service status or Resource scheduling mechanism, a 5G controller may be implemented by extension based on a CRD (Custom Resource Definition) mechanism of kubernets, and the working status of each network element may be detected in real time by the 5G controller.

Step S204, based on the adjustment strategy corresponding to the working state, a plurality of network elements are adjusted.

The adjustment policy in the above step may be a resource regulation and control policy issued by the user to the 5G controller through the client, and the policy may include information on how to adjust resources of each network element in different working states. In different application scenarios, different network elements often need to be adjusted in different ways, so that a user can adjust and update the adjustment policy at any time according to actual application needs, and send the adjustment policy to the 5G controller.

In an optional embodiment, after detecting the operating state of each network element, the 5G controller may match the state with an adjustment policy issued by a user, and if an adjustment policy matching the state exists, that is, if the user issues an adjustment policy how to perform adjustment when each network element is in the above state, each network element may be adjusted according to the adjustment policy.

The following describes in detail resource scheduling methods of different network elements in different application scenarios with reference to the system architecture shown in fig. 3. First, as shown in fig. 3, a 5G core network deployed in a containerization manner may be constructed, a CRD mechanism extension based on K8S is used to implement a 5G controller, and by detecting the working state of each network element and issuing a uniform adjustment policy, uniform scheduling of each network element based on the state and the resource usage is implemented, so as to better serve users.

In an optional application scenario of end-to-end availability adjustment, since a plurality of network elements need to cooperate with each other to provide a complete 5G core network service, when the working state of one or more network elements located behind in the whole service flow is abnormal, even unavailable, for example, AMF is available, but SMF, UDM or UPF is unavailable, since the connection between the front AMF and the base station is normal, the user will repeatedly try to activate, and since the backend service is unavailable, AMF can only reply to the user activation failure, which is very easy to generate a signaling storm, and after multiple activation failures, the user will enter a silent state, and even if the backend service is recovered to be normal, the user will not try to reactivate, and can only manually set the terminal to reactivate to provide the service, for the industrial scenario terminal, which will greatly affect the industrial production. In order to avoid the above problems, a user may issue a resource regulation and control policy to the 5G controller, the 5G controller continuously detects the working state of each network element, and once the working state of the network element located at the rear end is detected to be abnormal or even unavailable, the state of the AMF is actively set as unavailable, that is, the ports of the AMF and the base station are closed, so that the base station closes the corresponding cell (the closing of the cell by the base station under the condition of no AMF availability is a standard implementation, which is not specifically limited in the present application), thereby avoiding a signaling storm caused by the repeated attempts of activation by the user, and also avoiding the repeated failure and silence entering; after the 5G controller detects that the backend service is recovered, the AMF state may be set to be available again, that is, the ports of the AMF and the base station are opened, and the normal service is recovered.

In another optional application scenario of end-to-end network adjustment, under the condition of limited resources, when the partial 5G service load is higher and the partial 5G service load is lower, for example, the number of users is larger but the data transmission amount of a single user is smaller, the AMF/SMF load is higher, and even a new user cannot be accessed, but the UPF load is lower, and there is still a margin because the resource allocation is not uniform, so that the resource utilization rate of the whole 5G core network is insufficient, and even the application requirement cannot be met. In order to avoid the above problems, a user may issue a resource regulation and control policy to the 5G controller, the 5G controller continuously detects the load state of each network element, and once the condition that the resource distribution is not uniform is detected, the load of some network elements is higher, and the load of other network elements is lower, the resources may be fully distributed, that is, the resources with low load are reduced, and the resources with high load are expanded, so that the resource utilization rate of the whole 5G core network is balanced, and the service may be normally provided to the user.

By the scheme provided by the embodiment of the application, the working states of a plurality of network elements included in the core network can be detected, and the plurality of network elements are adjusted based on the adjustment strategy corresponding to the working states, so that the purpose of resource regulation and control of the core network is achieved. It is easy to note that, because a plurality of network elements are deployed in the container cluster, and each network element is adjusted through the working state and the adjustment strategy, unified and automatic adjustment of states and resources among a plurality of services in the 5G core network is realized, the technical effect of improving the service reliability of the whole 5G core network is achieved, and the technical problem that the normal use of a user is influenced due to abnormal network element service states included in the 5G core network in the related art is solved.

In the above embodiments of the present application, the above working states may include: an operating state, wherein adjusting the plurality of network elements based on the adjustment policy corresponding to the operating state comprises: and under the condition that the operating state of a first network element in the plurality of network elements is detected to be normal but the operating states of other network elements are detected to be abnormal, adjusting the operating state of the first network element to stop operating, wherein the first network element is connected with a base station connected to the core network.

The above-mentioned operation status may refer to a status of whether each network element service is available, and if the working status of the network element is normal, it indicates that the network element service is available; and if the working state of the network element is abnormal, indicating that the network element service is unavailable. The first network element may be an AMF, but is not limited thereto, and may also be the first network elements providing services in the whole service flow.

In an optional embodiment, for the purpose of adjusting end-to-end availability, the 5G controller may continuously detect the operating states of the network elements, and if it is detected that the operating state of the first network element is normal and the operating states of the other network elements are abnormal, that is, the first network element service is available and the second network element service is unavailable, the operating state of the first network element may be set to be out of operation, that is, set to be unavailable.

In the foregoing embodiment of the present application, adjusting the operation status of the first network element to stop operation includes: and closing the communication port between the first network element and the base station.

In an optional embodiment, in order to set the operation state of the first network element to stop operating, that is, to set the first network element to be unavailable, the communication ports of the first network element and the base station may be closed, so that the base station cannot acquire an available network element and close a corresponding cell, thereby avoiding a signaling storm caused by repeated attempts of activation by a user and a silence entering due to repeated failures.

In the above embodiment of the present application, after the adjusting the operation status of the first network element to stop operating, the method further includes: and after detecting that the operation states of other network elements are recovered to normal, adjusting the operation state of the first network element to normal operation.

In an optional embodiment, after the operating state of the first network element is set to the stop state, that is, the first network element is set to be unavailable, the 5G core network cannot provide services for the user, in order to ensure that the 5G core network can timely provide services for the user, the 5G controller may continue to detect each network element, especially other network elements with abnormal operating states, if it is detected that the operating states of all network elements are normal, that is, the operating states of other network elements in the original operating state are restored to normal, it indicates that the 5G core network can serve the user at this time, the operating state of the first network element may be adjusted to normal operation, so that the user can access the 5G core network through the base station.

In the above embodiment of the present application, adjusting the operation state of the first network element to normal operation includes: and opening a communication port between the first network element and the base station.

In an optional embodiment, the operation state adjustment manners of the first network element are the same, and therefore, the communication port that has been closed may be re-opened, so that the base station may normally communicate with the first network element, the base station re-opens the corresponding cell, and the entire 5G core network is recovered.

In the above embodiments of the present application, the above working states may include: the resource utilization rate, wherein the adjusting the plurality of network elements based on the adjustment strategy corresponding to the working state comprises: and under the condition that the resource utilization rate of a second network element in the plurality of network elements is detected to be greater than a first preset threshold value, the resources of the plurality of network elements are redistributed, so that the resource utilization rate of the second network element is smaller than the preset threshold value.

The first preset threshold may be a resource utilization threshold used for determining that the resource utilization of the second network element is higher, and may be set according to actual needs of different application scenarios.

In an optional embodiment, for the purpose of end-to-end network adjustment, the 5G controller may continuously detect the operating states of the network elements, and once it is detected that the resource allocation is not uniform, the load of the second network element is higher, and the loads of other network elements are lower, so that the resources may be fully allocated to balance the resource utilization rate of the entire 5G core network.

The second preset threshold may be a resource utilization threshold used for determining that the resource utilization of the target network element is low, and may be set according to actual needs of different application scenarios.

In an optional embodiment, if it is detected that the original allocations of the multiple network elements are not uniform, the resources of the entire 5G core network may be reallocated, the target network element with a lower resource utilization rate is subjected to capacity reduction, and the second network element with a higher resource utilization rate is subjected to capacity expansion, that is, the resources allocated to the target network element are reduced, and the redundant resources are reallocated to the second network element.

In the above embodiments of the present application, the above working states may include: an operating state, wherein adjusting the plurality of network elements based on the adjustment policy corresponding to the operating state comprises: determining the number of third network elements and the number of fourth network elements in normal operation state in the plurality of network elements; and under the condition that the number of the third network elements is different from that of the fourth network elements, increasing or reducing the number of the fourth network elements.

The third network element may be a network element that implements a previous service in the service flow of the 5G core network, and the fourth network element may be a network element that implements a subsequent service in the service flow of the 5G core network.

In an alternative embodiment, the core network comprises a plurality of network elements of different types, the same type of network element may be a plurality, in order to realize the end-to-end balance adjustment, a user can issue an adjustment strategy to the 5G controller, detecting the operation state of each type of network element through the 5G controller, determining the number of the network elements with normal operation state, if the number of the network elements implementing the two previous and next services in the service flow is different, the number of the network elements can be adjusted, so that the number of the network elements implementing the two previous and next services is the same, for example, the number of the third network elements may be increased or decreased, the number of the fourth network elements may be increased or decreased, the number of the third network elements and the number of the fourth network elements may be adjusted at the same time, the network elements with a larger number are deleted, and the network elements with a smaller number are newly added. In this embodiment of the present application, in order to ensure that the 5G core network can normally serve, the number of network elements that implement the next service, that is, the number of the fourth network element, may be increased or decreased, that is, the network element of the type of the fourth network element is added or deleted.
