Mobile communication terminal, the radio station switching method and radio station switching program

摘要

PROBLEM TO BE SOLVED: To efficiently switch connected radio station devices to shorten the period in which communication cannot be performed.;SOLUTION: In the middle of communicating with a first access point of a plurality of access points, radio field strength E1 of a first channel is detected (Step S21). In accordance with the fact that the detected radio field strength E1 of the first channel is lower than a first threshold value (YES at S22), a communication channel is temporarily switched from the first channel to a second channel and radio field strength E2 of the second channel is detected (S23). On the basis of the radio field strength E2 of the second channel, a second access point to be communicated next from the plurality of access points is determined (S32). In accordance with the fact that the radio field strength E1 of the first channel is lower than a second threshold value (YES at S28), a reassociation request for requesting the second access point for connection with handoff is transmitted (S33).;COPYRIGHT: (C)2013,JPO&INPIT
