It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The slice resource allocation method provided by the application can be applied to an application environment shown in fig. 1. Wherein the power device 101 communicates with the base station 102 via a network. The power device 101 may be a terminal device that successfully establishes a signaling connection with a network slice of the base station 102, where the terminal device that successfully establishes a signaling connection with the network slice of the base station 102 may be a terminal device that is successfully registered on an AMF (Action Message Format, abbreviated as AMF) network protocol, and an nsai (Network Slice Selection Assistance Information, abbreviated as nsai) allowed in a user context of the terminal device includes an S-nsai (Single Network Slice Selection Assistance Information, abbreviated as S-nsai) corresponding to the network slice, and a connection state of the terminal device is in a connection state (CM-CONNECTED). The power device may communicate with a base station via an operator network, and the base station 102 may allocate network resources for the network slice corresponding to the power device 101.

In one embodiment, as shown in fig. 2, a slice resource allocation method is provided, and the method is applied to the power equipment in fig. 1 for illustration, and includes the following steps:
step 201, slice configuration information is determined according to operation information of the power equipment, and the slice configuration information is sent to the base station.
The slice configuration information comprises bandwidth allocation information of each network slice in a plurality of network slices corresponding to a plurality of services of the power equipment, wherein the bandwidth allocation information is used for indicating a target resource for bearing emergency services in resources of the network slice corresponding to the bandwidth allocation information.
One power device may run a plurality of services, and after the 5G technology is applied to the power system, one network slice may be allocated to each service running on the power device, or one network slice may be allocated to a plurality of services; the service data generated by each service is transmitted in network communication through the bandwidth resource of the corresponding network slice, alternatively, one service may generate a plurality of different types of service data, for example: the data of the business in normal operation, the alarm data in error and the like can be called as emergency business when the business is abnormal or the business operates in error; however, for different types of service data of a service, different bandwidth resources in the corresponding network slice of the service can be processed; that is, the resources of the network slice may be divided into a target resource carrying service data of the traffic in a normal state and a target resource carrying service data of the traffic in an abnormal state.
Optionally, the power equipment may determine bandwidth allocation information of each network slice corresponding to the power equipment according to current real-time operation information of the power equipment, where the bandwidth allocation information includes a target resource for carrying emergency services in resources of the network slice; alternatively, the real-time operation information of the power device may include a bandwidth demand of each service, and then, a target resource required by each service in an emergency may be determined according to the bandwidth demand of each service; optionally, the bandwidth demand of each service may be multiplied by a preset proportion parameter to obtain a target resource required by each service in an emergency; further, bandwidth allocation information of each network slice may be determined according to target resources required by each service in an emergency; for example: in the case that one network slice carries one service, the target resource required by the service in the emergency can be determined as the target resource for carrying the emergency service in the resources of the network slice; in the case that one network slice carries a plurality of services, the sum of target resources required by the plurality of services in the emergency can be used as the target resource for carrying the emergency service in the resources of the network slice. By the method, the bandwidth allocation information of each network slice corresponding to the power equipment can be determined, namely, the slice configuration information of each network slice corresponding to the power equipment can be obtained.
After the power equipment determines slice configuration information according to the running information of the power equipment, the slice configuration information can be sent to the base station, so that the slice configuration information of the power equipment is stored in the base station which is in signaling connection with the power equipment, and the base station can allocate target resources for each network slice of the power equipment according to the slice configuration information.
