Abstract
When frequencies are being scanned to seize a control channel immediately after the end of a call, if there arises a call request, the call request is stored, and a calling operation is automatically initiated after a control channel has been seized. When a call request is stored, if a predetermined length of time has elapsed before a control channel is seized, the stored call request is discarded.
