摘要： A handover control method in a mobile communication system that performs handover control by switching base stations that communicate with a mobile terminal as the mobile terminal moves. In this handover control method, a mobile control device selects one or more handover base station candidates based on the communication state, and based on the communication capabilities of the handover base station candidates, decides a transmission rate for multicasting communication data, and transmits communication data to each of the handover base station candidates at the decided transmission rate, and a handover base station candidate that is decided as a handover base station sends the saved multicast communication data to the mobile terminal.

摘要： During handover, an origin base station saves data packets for a mobile station, as well as instructs the mobile station to switch communication to a destination base station, and requests a host station to switch the base station that communicates with that mobile station from the origin base station to the destination base station. After that, when in accordance to the switching request it is possible to save data packets, the host station begins to save the data packets for the mobile station in the place of the origin base station, and after communication between the mobile station and the destination base station has become possible, sends the saved data packets to the mobile station via the destination base station.

摘要： The present invention is directed to a handover method, a base station, and a mobile station for a CDMA mobile communication system, to improve the efficiency of inter-frequency handover. Handover is achieved between a mobile station and distributed base stations and the like. The base stations have different traffic channel frequencies. In a normal mode, a signal unit transmitted through a traffic channel consists of four frames. In a compression mode, the base station temporally compresses two normal frames into a single frame period and then transmits the frames twice through the traffic channel. The mobile station switches the reception frequency of a present traffic channel and the reception frequency of a perch channel of the destination base station at intervals of two normal-mode frames at the head of each frame received from the perch channel. The mobile station then restores frames received from the traffic channel in the compression mode to the original frames and processes them. At the same time, the mobile station extracts a system frame number from two frames received from the perch channel.
