MOBILE TERMINAL MACHINE, METHOD FOR SELECTING WAITING-CHANNEL IN SHARED MOBILE COMMUNICATION SYSTEM, WAITING-CHANNEL SELECTION PROGRAM, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a mobile terminal machine which suppresses the position registration traffic taken with the position transfer of the mobile terminal machines among shared mobile communications systems.;SOLUTION: In a case of performing communication while selecting a waiting channel between first and second mobile communications systems between which parts of the areas 22 to 40 formed by radio waves are overlapped, the frequency band of the mobile communication system, to which the position registration has been made, is stored in a memory part 18 of the mobile terminal machine 10. In selecting the waiting channel, a control part 16 searches the frequency band of the mobile communications system, stored in the memory part 18 in the last position registration, and preferentially selects the waiting channel of the mobile communications system of the detected frequency band.;COPYRIGHT: (C)2006,JPO&NCIPI
