Handover control apparatus, mobile station, base station, handover control server, and handover control method

摘要

In handover control, a data collection unit collects measurement data that indicates communication quality of uplink and downlink paths between a mobile station and base stations. A candidate evaluation unit evaluates which base station is optimal for uplink, as well as which base station is optimal for downlink, based on the measurement data. A station selection unit determines which link has priority, either uplink or downlink, according to the class of data services that the mobile station uses in radio communication, and selects as a target base station for handover the base station that has been determined as being optimal for the link having priority.
