Description

Method, product, system and medium for reducing paging load in wireless communications
Technical Field
The invention relates to the technical field of wireless communication, in particular to a method, a device, user equipment and a wireless communication system for reducing paging load in cellular wireless communication.
Background
In current cellular communications, the UE ID used when paging the terminal is S-TMSI, which includes:
Figure BDA0001579800940000011
among them, the mobile terminal needs 40BITs for identifying the terminal identity when paging the terminal because the mobile terminal needs BIT training (SIZE (8)).
Currently, in the fifth generation mobile communication NR standard, NR introduces a beam scanning mechanism, however, beam scanning is required for paging transmission, and one paging message transmission needs to occupy multiple time slots, which results in high paging load.
If the hash value of the UE ID is used for paging, since there may exist a plurality of different UE IDs corresponding to the same hash value, there is a case where the UE is erroneously called, and the UE needs to access the network for confirmation after receiving the paging, which causes the standby power consumption of the UE to increase. The prior art documents do not fully consider how to deal with, which is also a problem in the prior art.
Further, the technical problem is particularly apparent and prominent in the current situation where the 5G wireless communication standard is mature and in the communication environment where the 5G NR standard has been introduced.
