Network slicing (network slicing, NS) is a new concept introduced under the 5G standard. Simply put, it is to divide a physical network into multiple virtual end-to-end networks. Each virtual network is logically independent. Any one Failure of a virtual network will not affect other virtual networks. Existing network slicing technologies are mainly carried out in the following two directions: (1) According to different services and deployment scenarios, the 5G radio access network (radio access network, RAN) architecture can be divided into centralized units (central unit, CU) At the two levels of the distributed unit (DU), the RAN side protocol stack can be flexibly customized and segmented based on the characteristic type of the slice. The RAN network is the bearer of the slice service directly facing users. However, the various RAN-side protocol stack splits introduced under CU/DU separation are mainly aimed at the delay requirements of services, that is, services that require high speed and large number of connections, and various protocol stacks under CU/DU separation The segmentation method cannot achieve better adaptation. (2) Network slicing according to the wireless resource allocation method: frequency and time resources are allocated to each specific slice in a fixed manner, and users can use these static wireless resources to access the slice network; or, the scheduling management service of the network slice is based on The real-time arrival of slice service requests allocates time-frequency resources as needed, and ensures balanced allocation of resources between slices. However, this method basically reserves resources for slices in a baseband core, so when a baseband core This method cannot meet higher business needs when resources are tight and cannot be reserved.

At this time, only the RLC uplink sub-service is processed in the original baseband core, while the RLC downlink sub-service is divided into processing in another baseband core, then at this time, it can not only meet the rate requirement of the total uplink rate of 0.2Gbps in this scenario, but also meet the rate requirement of the total downlink rate requirement value of 1.3Gbps. The embodiment of this application can realize RLC uplink The rates of sub-services and RLC downlink sub-services are not reduced, so as to achieve higher service requirements.

S202. If the total rate demand value is greater than the second preset rate threshold, divide the service of the cell into M sub-services according to the number of RLC service bearer categories, and deploy at least one sub-service for each of the M sub-services A network slice, M is a natural number greater than or equal to three.

S301. If the total connection number demand value is greater than or equal to the first preset connection number threshold and less than or equal to the second preset connection number threshold, divide the service of the cell into MAC uplink sub-service and MAC downlink sub-service, and provide MAC At least one network slice is deployed for the uplink sub-service and the MAC downlink sub-service respectively.

After the base station obtains the total connection number requirement value of the cell, determine the size of the total connection number requirement value, if the total connection number requirement value is greater than or equal to the first preset connection number threshold and less than or equal to the second preset connection number threshold value, then Segmenting the service of the cell into a MAC uplink sub-service and a MAC downlink sub-service, and deploying at least one network slice for the MAC uplink sub-service and the MAC downlink sub-service respectively. Wherein, the first preset connection number threshold and the second preset connection number threshold can be artificially set according to the basic configuration of the base station, for example, the first preset connection number threshold is 5000, and the second preset rate threshold is 20000 number, or other values, which are not limited here; the MAC uplink sub-service may be the number of users using the upload service, and the MAC downlink sub-service may be the number of users using the download service, which is not limited here.

Example 3: The baseband board in a base station includes multiple baseband cores. The capability of each baseband core is: support a total of 10,000 downlink users and 3,000 uplink users, which is the maximum total number of baseband cores. The number of connected users is 13,000, and the first preset threshold of the connection number of the base station is set to 5,000, and the second preset threshold of the number of connections is 20,000. According to the service requirements of the cell covered by the base station, the network scenario of the cell is determined as Large-scale Internet of Things mMTC, and the required value of the total number of connections to obtain the cell is 15,000, of which, the required value of the total number of downlink connections is 13,000, and the required value of the total number of uplink connections is 2,000. At this time, the existing technology can only Reducing the required value of the total number of downlink connections or the required value of the total number of uplink connections cannot meet such business requirements, but in this embodiment of the application, the business of the cell can be divided into MAC uplink sub-services and MAC downlink sub-services, And deploy at least one network slice for the MAC uplink sub-service and the MAC downlink sub-service respectively, that is: keep the MAC uplink sub-service in the original baseband core for processing, and divide the MAC downlink sub-service to another baseband core for processing, At this time, only the MAC uplink sub-service is processed in the original baseband core, and the MAC downlink sub-service is divided into another baseband core for processing. In this case, the total number of uplink connections in this scenario is 2,000. It can meet the connection number requirement of 13,000 total downlink connections, and the embodiment of the present application can realize that the connection numbers of the MAC uplink sub-service and the MAC downlink sub-service are not reduced, thereby realizing higher service requirements.

In this scenario, it can not only meet the demand for the total number of connections of the sub-services of the first UE group in this scenario, which is 13,000, but also meet the requirement of the total number of connections for the sub-services of the second UE group in this scenario. 13,000 and the third UE group require a total connection number of 4,000 connections. Therefore, the embodiment of the present application can realize that the total connection number requirement is not reduced, thereby realizing more service connection number requirements .
