摘要

PPROBLEM TO BE SOLVED: To allow radio equipment Tb for groups to be managed to make a call to radio equipment Ta for a management group without trouble and to perform power saving by suppressing a channel scan time of Ta in a radio communication system 10 in which a management group A is separated from groups B to D to be managed. PSOLUTION: Intermediary radio equipment Tp is made to maintain a waiting state of a data channel fcont for channel scan different from a data channel fa for a management group. Tb makes a call to Ta by a speech communication channel fb for groups to be managed of a self-group. Tb makes a switch from fb to fcont to transmit a channel scan request and the ID of Ta in fcont if Ta does not respond. When fcont receives the channel scan request, fcont transmits a channel scan request with Ta as a destination in fa by switching fcont to fa. Upon receiving the channel scan request in fa, Ta performs channel scan. Tb makes a call to Ta in fb again. PCOPYRIGHT: (C)2009,JPO&INPIT
