In a frequency band transfer using a fast session transfer (FST), a timeout value (link loss timeout: LLT) is set on the basis of a change of the communication status. Then, a transfer setting sequence, which includes a step of transmitting the set timeout value to a radio station on the other end of communication, is executed. Then, a frequency band transfer is executed at a lapse of time of the timeout value from a time when the transfer setting sequence completes. For example, a large timeout value (LLT = T1) is set at the establishment of a connection, and, for example, the LLT is changed (LLT = T2-T4) on the basis of a change of the transmitted data status or communication path status. |
