The existing network slicing technology is mainly performed from the following two directions: (1) according to different services and deployment scenarios, the overall architecture of a 5G Radio Access Network (RAN) can be divided into two levels, namely a Central Unit (CU) and a Distributed Unit (DU), the RAN-side protocol stack can be flexibly customized and segmented based on the characteristic types of the slices, and the RAN network is a bearer for the slice services directly facing users. However, various RAN-side protocol stack partitions introduced under CU/DU separation mainly address the delay requirements of services, i.e., services requiring a large rate and a large number of connections, and various protocol stack partition modes under CU/DU separation cannot be better adapted. (2) Network slicing is carried out according to a wireless resource allocation mode: allocating frequency and time resources to each specific slice in a fixed mode, wherein users can access the slice network by using the static wireless resources; or, the scheduling management service of the network slice allocates time-frequency resources as required according to the real-time arrival condition of the slice service request and ensures the balanced allocation of the resources among the slices, but the method basically reserves the resources for the slices in one baseband core by the base station, so when the situation that the resources are in shortage and can not be reserved occurs in one baseband core, the method can not meet higher service requirements.
