101: and the target network functional entity receives the service request sent by the terminal equipment.
In this embodiment, the target network function entity includes one or more network function entities, and the terminal device may be a terminal device as shown in fig. 1, where the service request may include a user ID, an operation type and data required for operating the service request, for example, the operation type may be sending a message, downloading data, deleting data, modifying data, and the like.

In this embodiment, the monitor monitors and determines whether a service request comes from the terminal device in real time, and if it is monitored that the service request comes from the terminal device, the monitor sends a reporting instruction to the terminal device, and the terminal device reports the service request to the routing center after receiving the reporting instruction.
103: and the routing center evaluates the service request according to the preset service priority evaluation strategy to obtain service priority, and distributes a target controller for the service request in the plurality of controllers according to the service priority.
In this embodiment, the preset service priority evaluation policy refers to calculating different service priorities by evaluation according to different service requests.
The mapping relationship between the preset service request and the service priority can be stored in the routing center, and after the routing center receives the service request reported by the terminal device, the corresponding service priority is obtained from the mapping relationship between the preset service request and the service priority according to the service request. The mapping relation between the service request and the service priority can configure the service priority according to the importance degree of the service request, and the higher the importance degree level is, the higher the service priority level is, the target controller is preferentially distributed; conversely, the lower the importance level and the lower the traffic priority, the later the target controller is assigned.
Specifically, the mapping relationship between the service request and the service priority may be implemented by a hash table, for example, by obtaining a service request identifier to obtain a service request hash value, and obtaining a corresponding service priority from a hash table pre-stored in the routing center according to the service request hash value, where the smaller the service request hash value is, the higher the service priority is; conversely, the larger the hash value of the service request is, the lower the service priority is. Other evaluation calculation methods may also be adopted, and the application is not limited thereto.
In addition, the evaluation and judgment of the importance degree of the service request can comprise a plurality of dimensions, each dimension of the service request corresponds to a service priority, one dimension with the highest service priority can be selected as an evaluation standard, a plurality of dimensions can also be selected as evaluation standards, and the service priority is obtained through comprehensive calculation.
The service request is evaluated by the routing center according to a preset service priority evaluation strategy to obtain service priority, and the target controllers are distributed to the service request in the plurality of controllers according to the service priority, so that the controllers are distributed according to the service priority of the service request, the service request with high priority is guaranteed to be distributed preferentially, the service quality of the server is improved, the load balance of each controller is favorably realized, and the controller is prevented from being out of order due to the fact that the processing workload exceeds the load.
In some embodiments, referring to fig. 3, the preset service priority evaluation policy includes a correspondence between a service type and a service priority, and the evaluating, by the routing center, the service request according to the preset service priority evaluation policy to obtain the service priority includes:
201: and the routing center acquires the service type of the service request.
Specifically, the service types may be classified according to specific services.
202: and the routing center determines the service priority of the service request according to the service type and the corresponding relation between the service type and the service priority.
In order to simplify and quickly obtain the service priority, the service priority can be obtained by evaluating the service type to which the service request belongs, similarly, the corresponding service priority can be obtained from the mapping relation between the preset service request and the service priority according to the service type, the mapping relation between the service type and the service priority can configure the service priority according to the importance degree of the service type, the higher the importance degree level is, the higher the service priority is, and conversely, the lower the importance degree level is, the lower the service priority is.
In some embodiments, referring to fig. 4, said allocating a target controller for said service request among said plurality of controllers according to said service priority comprises:
301: determining a controller of the plurality of controllers that currently has load capability.
A controller with load capability refers to a controller that can continue to apply a load, for example, a controller with load capability of 1000, currently loaded with 10, and remaining loadable 990, then the controller is a controller with load capability.
302: and if the controller with the load capacity has an idle state, selecting the controller in the idle state as the target controller.
A controller in an idle state refers to a controller without load, for example, if the controller has a loadable capability of 1000, is currently loaded with 0, and remains loadable with 1000, then the controller is a controller with an idle state.
303: and if no controller in an idle state exists in the controllers with the load capacity, selecting the controller with the highest loadable capacity from the controllers with the load capacity as the target controller.
The controller with the highest loadable capability refers to the controller that can continue to apply the maximum load, for example, the first controller has a loadable capability of 1000, is currently loaded with 10, and remains loadable 990; the second controller loadable capacity is 1000, currently loaded 20, remaining loadable 980; the third controller has a loadability of 1000, is currently loaded with 30, and has a remaining loadability of 970, and the former controller is the controller with the highest loadability.
Selecting the controller in the idle state as the target controller, or selecting the controller with the strongest loadable capability as the target controller, so that the configuration processing capability of the target controller is kept maximized, and the service processing efficiency can be improved; in addition, each controller can be guaranteed to be allocated with service requests, and the number of the service requests allocated to each controller is equivalent, which is beneficial to realizing load balancing.
In some embodiments, referring to fig. 5, said allocating a target controller for the service request among the plurality of controllers according to the service priority further comprises:
401: and if the controller with the load capacity does not exist in the plurality of controllers currently, determining the release priority of the service request currently allocated to the plurality of controllers.
The release priority of the currently processed service request of the plurality of controllers may be determined according to the service priority of the currently processed service request, for example, the lower the service priority of the currently processed service request is, the higher the release priority is; otherwise, the higher the service priority of the currently processed service request is, the lower the release priority is.
In addition, the release priorities of the currently allocated service requests of the plurality of controllers can be obtained by calculation according to the ratio of the residual load capacity to the loadable capacity of the controllers, and the greater the ratio of the residual load capacity to the loadable capacity is, the higher the release priority is; conversely, the smaller the ratio of remaining load capacity to loadable capacity, the lower the release priority. For example, if the ratio of the remaining load capacity to the loadable capacity of the first controller is 0.9 and the remaining load capacity of the second controller is 0.8, the release priority of the first controller is greater than the release priority of the second controller, which can avoid the influence of the release of the controllers on the processing progress of the ongoing service request.
402: determining, among the plurality of controllers, a releasable controller according to the release priority.
Specifically, the controller with the higher release priority is released with priority, and the controller with the lower release priority is released with hysteresis.
403: and the releasable controller is used as the target controller.
The releasable controller is used as the target controller, the allocation of newly-added service requests can be realized without additionally adding a controller, the problem that the controller is overloaded and fails due to the excessive number of the service requests allocated by a single controller is avoided, the influence caused by the sudden increase of the number of the service requests can be minimized by releasing the controller corresponding to the service request with low service priority, and the situation that the service request with higher importance degree cannot be allocated with the controller in time is avoided.

503: and the routing center evaluates the service requests according to the preset service priority evaluation strategy to obtain a plurality of service priorities, and allocates corresponding controllers for the service requests in the controllers according to the service priorities.

602: and determining a plurality of service priorities of the plurality of service requests according to the service types of the plurality of service requests and the corresponding relation between the service types and the service priorities.

701: and sequencing the service priorities and determining a sequencing order.
Specifically, the sorting order may be obtained by sorting the service priorities from high to low or from low to high.
702: and determining the distribution sequence of the controller according to the sequencing sequence.
Specifically, when the sorting order is obtained by sorting the service priorities from high to low, the distribution order is consistent with the sorting order; when the sorting order is obtained by sorting the plurality of service priorities from low to high, the distribution order is opposite to the sorting order.
703: and sequentially distributing the target controllers for processing the plurality of service requests among the plurality of controllers according to the distribution sequence of the controllers.
Controllers in the forward position of the dispensing sequence are assigned preferentially as target controllers and controllers in the rearward position of the dispensing sequence are assigned late as target controllers.

801: and the monitor monitors whether the target network functional entity receives the service request sent by the terminal equipment within a preset time period.
802: and when the target network functional entity does not receive the service request sent by the terminal equipment within the preset time period, the routing center turns off and recovers the target controller distributed for the service request.
It can be understood that when no service request comes from the terminal device, the corresponding target controller is shut down and recovered, so that the resource space can be effectively saved.
In one embodiment, referring to fig. 10, the controller allocation method further includes:
901: and the routing center pre-estimates the service requests of the future target time period in the network service system to obtain a request quantity pre-estimated value.
