MOBILITY MANAGEMENT METHOD, ACCESS NETWORK DEVICE, AND TERMINAL DEVICE

WIPO Patent Application WO/2018/188613

A1

Disclosed in multiple aspects of the present invention are a mobility management method, an access network device, and a terminal device. A base station system comprises a centralized unit and a distributed unit, the centralized unit communicates with the distributed unit, and the distributed unit communicates with the terminal device through an air interface. The method comprises: a centralized unit selects a target cell as a secondary cell according to a measurement report submitted by a terminal device, and sends allocation information of the target cell to the terminal device by means of a distributed unit; the centralized unit receives primary cell change indication information sent by the distributed unit, and reallocates an air interface resource to the target cell according to the primary cell change indication information, and generates reallocation information; and the centralized unit sends the reallocation information to the terminal device by means of the distributed unit. By means of the mobility management method and apparatus and the terminal device, and the handover delay can be reduced.
