The present disclosure provides a mobility management method and device, wherein the method includes: receiving an uplink reference signal periodically sent by a user equipment; generating network indication information according to change information of the uplink reference signal; Delivering the network indication information, so that the user equipment performs corresponding operations according to the network indication information and feeds back operation information; and performs mobility management on the user equipment according to the operation information sent by the user equipment. With the mobility management method provided by the present disclosure, the mobility management is performed based on the uplink reference signal, the information exchange process is simple, and the signaling overhead is small, which can effectively shorten the cell change time, improve the mobility management efficiency of the system, and improve the high-speed movement of the user equipment. communication performance.
Description
technical field [0001] The present disclosure relates to the technical field of computer communication, in particular to a mobility management method and device. Background technique [0002] In existing mobile communication systems such as 4G networks, the mobility management of user equipment (UE) is based on the downlink, and the general process is as follows: the network side equipment sends cell measurement signaling carrying measurement rules to the UE; the terminal Detect the downlink data of the access cell or neighboring cells according to the above measurement rules, obtain the measurement results and send them to the network side equipment; when the network side equipment determines that the UE needs to perform cell handover based on the above measurement results, it selects a cell with a better communication performance for the UE. Good target neighborhood. [0003] However, when the user equipment is in a high-speed mobile scene, such as a high-speed train, it ...
