Patent ID: 8538412

Claim:
A mobile station capable of communication through a plurality of radio interfaces differing in at least one among radio scheme and frequency band, the mobile station comprising: a determining unit that determines execution of concurrent communication based on a communication state of the mobile station, the concurrent communication concurrently using the radio interfaces for communication; a communicating unit that performs the concurrent communication based on a determination result obtained by the determining unit; and a receiver that receives, from a base station, a determination condition of the concurrent communication, the determination condition having parameters including the communication state, wherein the determining unit determines the execution of the concurrent communication based on the determination condition and the communication state, the determination condition includes judging-aided information correlating the communication state with the number of the radio interfaces, the determining unit determines the number of the radio interfaces used in the concurrent communication based on the judging-aided information and the communication state, and the communicating unit concurrently uses the number of the radio interfaces determined by the determining unit to perform the concurrent communication.
