METHOD, APPARATUS AND SYSTEM FOR CELL HANDOVER IN COMMUNICATION SYSTEM SUPPORTING CARRIER AGGREGATION

摘要

A method, apparatus and system for cell handover in the communication system supporting Carrier Aggregation (CA). The method includes: after receiving a performance measurement report for one or more neighboring cells from the served terminal, according to the performance measurement report, and basing on the CA mode for one or more candidate BSs corresponding to the one or more neighboring cells, a source Base Station (BS) in a communications system selects an algorithm suitable for the CA mode to calculate the priority levels of the one or more candidate BSs; from the one or more candidate BSs, selecting the BS having the highest priority as a target BS; and selecting one more cells to access from all cells being subject to the target BS in the one or more neighboring cells.

主权项

1. An electronic device at network side, comprising
circuitry, configured to acquire performance measurement report of one or more neighbor cells from a terminal device served by the electronic device; determine a target base station for the terminal device from one or more candidate base stations corresponding to the one or more neighbor cells based on the performance measurement report; and select one or more cells to be accessed by the terminal device from cells of the target base station, wherein the determination of target base station precedes selection of cells to be accessed by the terminal device, and the determination of target base station is based on capability of carrier aggregation of the candidate base stations.
