The terminal 11 may be, but is not limited to, a mobile phone, a smart car, an unmanned aerial vehicle, an internet of things device, etc. Access network 12 includes base stations or access points, etc. The base station may be a 4G base station, a 5G base station, or an evolved base station after 5G. The application server 15 is used to provide one or more service functions.

The access network request sent by the terminal 11 enters the network slice management function entity 161 through the access network slice subnet management function entity 162, and the network slice management function entity 161 may send an access network instruction to the access network slice subnet management function entity 162 according to the access network request, and carry the network slice subnet management function entity 163 and the core network slice subnet management function entity 164. The network slice subnet management function 162, the bearer network slice subnet management function 163 and the core network slice subnet management function 164 create network slices in the access network 12, the bearer network 13 and the core network 14, respectively.

Three kinds of services can be subdivided into more service types, and the following describes the bandwidth, time delay, moving speed and reliability indexes of various services:

it can be seen that some services have very high latency requirements. For the problem that the end-to-end time delay is difficult to ensure due to the fact that a single network slice transmits data streams with different flow modes, the network slice is selected according to the preset flow mode or the actual flow mode by identifying the actual flow mode of each data stream, so that message sequences in part of the network slices are transmitted according to the preset flow mode, and the time delay caused by mutual interference of the data streams with different flow modes in the network slice is overcome.
