Mobile station, network, and handover control method

摘要

In a parameter storage device, an offset value corresponding to a moving state (moving speed) and a serving frequency are stored. A parameter identifier reads from the parameter storage device an offset value corresponding to a serving frequency and a moving state. A measuring unit measures a radio communication quality of an inter-frequency cell. A measurement controller adds the offset value to the radio communication quality, to generate control information. The control information is transmitted via a transmitter to a network.

主权项

1. A mobile station for communicating with a network having a plurality of base stations in each of a plurality of different cells, comprising:
circuitry configured to
identify a moving speed of the mobile station;generate control information required by the network in implementing an inter-frequency handover; andtransmit the control information to the network,wherein the mobile station and the network are communicable with each other by using one of plural frequencies including a predetermined priority frequency that is used by the mobile station to access the plurality of different cells when the mobile station moves between the plurality of different cells, andwherein, when a serving frequency currently being used to communicate with the network is the priority frequency from among the plural frequencies and when the speed exceeds a reference moving speed, the circuitry is configured to change a content of the control information and reduce a number of times per unit time of transmitting the control information to the network.
