Abstract

The invention provides a method and a device for reducing paging load in cellular wireless communication, user equipment and a wireless communication system. Numbers of all access and mobility management functions connected with the base station and a list of codes corresponding to the numbers are broadcasted in the system information; the number part of the temporary mobile subscriber identification code in the paging message adopts the corresponding code broadcasted in the system message, and the compression access and the number of the mobility management functions enable the ID of the userequipment in the paging message to be reduced by some bits, so that the paging load is reduced, and meanwhile, the problem of wrong paging is not caused.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device, user equipment and wireless communication system for reducing paging load in cellular wireless communication. Background technique [0002] In current cellular communication, the UE ID used when paging a terminal is S-TMSI, and S-TMSI includes: [0003] [0004] Wherein, MMEC::=BIT STRING(SIZE(8)), therefore, 40 bits are required to identify the terminal identity when paging the terminal. [0005] The current fifth-generation mobile communication NR standard is being formulated. NR introduces a beam scanning mechanism. However, beam scanning is required to send paging. A paging message needs to occupy multiple time slots, which will lead to high paging load. [0006] If the hash value of the UE ID is used for paging, since there may be multiple different UE IDs corresponding to the same hash value, there may be cases of wrongly being c...
