Title:
SERVING CELL HANDOVER METHOD AND APPARATUS, AND SERVING CELL DETERMINATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/262480
Kind Code:
A1
Abstract:
Disclosed in the present application is a serving cell handover method. Specifically, a network device divides each cell into a plurality of rasters, acquires flow information corresponding to each raster, determines, according to the flow information corresponding to the rasters and a plurality of cells corresponding to the rasters, recommended accessed cells corresponding to the rasters, and sends the recommended accessed cells corresponding to the rasters to wireless access apparatuses corresponding to the cells. During practical application, a user equipment sends reference signal received power of a plurality of uplink beams to a first wireless access apparatus of a first cell; the first wireless access apparatus determines a target raster of the user equipment in beam space according to the reference signal received power of the plurality of uplink beams, and determines the recommended accessed cell corresponding to the target raster; and when the recommended accessed cell is a second cell, the first wireless access apparatus sends a handover instruction to the user equipment, so as to instruct the user equipment to access the second cell. It can be seen that when the recommended accessed cell is determined, flow information of the cell is taken into consideration to avoid the load of the determined recommended accessed cell being relatively high, thereby improving the usage experience of users.
