Further, on the basis of the above embodiment, the step S1 may include steps S11-S12 not shown in the figure:
and S11, identifying the video service through the downlink flow.
Specifically, in step S11, the downlink traffic may be counted in a PDCP (packet data convergence protocol) layer, and if the number of large packets received in X consecutive downlink periods T exceeds a preset threshold, the large packets are identified as a video service, where X is a positive integer.
For example, the large packet threshold may be 1000 bytes, which is not limited in this embodiment and may be set according to an actual situation; t is a monitoring period, and both T and X can be set according to actual conditions.

after identifying the main stream video service, putting the identified main stream video service to a video service initial access priority layer, if the time of the identified main stream video service in the video service initial access priority layer exceeds the initial access priority scheduling time, moving the identified main stream video service to the video service priority layer until the scheduling priority does not change before the identified main stream video service is finished.

7. Device according to claim 6, characterized in that the identification module is particularly adapted to
Identifying a video service through downlink flow;
after the video service is identified, the uplink packet feature words are matched with the preset feature words of the mainstream video manufacturer, and if the matching is successful, the mainstream video service is successfully identified.
8. The apparatus of claim 6, wherein the video service priority mechanism is:
the scheduling priority of the NGBR service of a common VIP user is greater than the scheduling priority of the video service initial access priority layer, greater than the scheduling priority of the new NGBR service priority layer and greater than the scheduling priority of the video service priority layer;
after identifying the main stream video service, putting the identified main stream video service to a video service initial access priority layer, if the time of the identified main stream video service in the video service initial access priority layer exceeds the initial access priority scheduling time, moving the identified main stream video service to the video service priority layer until the scheduling priority does not change before the identified main stream video service is finished.
9. An electronic device, comprising: a processor, a memory, a bus, and a computer program stored on the memory and executable on a first processor;
the processor and the memory complete mutual communication through the bus;
the processor, when executing the computer program, implements the method of any of claims 1-5.
10. A non-transitory computer-readable storage medium, having stored thereon a computer program which, when executed by a processor, implements the method of any one of claims 1-5.
