Document Type and Number:

WIPO Patent Application WO/2020/133209

Kind Code:

A1

Abstract:

The disclosure provides a mobility management method, device and a base station. The method comprises the following steps: when an inter-base-station interface is established with a neighboring base station, sending a request message to the neighboring base station, the request message being used for requesting to acquire information of support capability for an unlicensed frequency band of the neighboring base station; determining response information of the neighboring base station for the request message; and performing mobility management on the user equipment in the serving cell according to the response information. Adopting the mobility management method provided by the disclosure, the base station can perform mobility management on the UE in the servicing cell by using a correct mobility management strategy, thereby improving the mobility management accuracy of 5G NR system.
