Abstract

Multiple aspects of the invention disclose a mobility management method, access network equipment and terminal equipment. A base station system comprises a centralized unit and a distributed unit, thecentralized unit communicates with the distributed unit, the distributed unit communicates with the terminal equipment by virtue of an air interface, and the method comprises the following steps: according to a measurement report reported by the terminal equipment, selecting a target cell as an auxiliary cell by the centralized unit, and sending configuration information of the target cell to theterminal equipment by virtue of the distributed unit; receiving main cell change indication information, sent by the distributed unit, by the centralized unit, and performing air interface resource reallocation on the target cell according to the main cell change indication information and generating reconfiguration information; and sending the reconfiguration information to the terminal equipment by the centralized unit by virtue of the distributed unit. By virtue of the mobility management method and device as well as the terminal equipment, handoff delay can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a mobility management method, access network equipment and terminal equipment. Background technique [0002] With the rapid development of terminal equipment requirements and technologies, the 5th Generation mobile communication technology (5G) system or new radio access technology (New radio, NR) is coming soon, and the 5G system or NR system can provide a longer-term The evolution (Long Term Evolution, LTE) network has a faster transmission rate, and its maximum theoretical transmission rate can reach tens of gigabytes (Gigabyte, Gb for short) per second. [0003] The architecture of the access network in the existing 2 / 3 / 4G network is basically composed of the core network and the access network, and there is basically no interconnection at the service level between the access networks. For example, the Iur interface in 3G is used for signaling betwee...
