PURPOSE:To eliminate a complicated operation by storing plural vehicle numbers set by a caller, and after a call channel request signal is sent by a press, sending collectively the selection call data of plural vehicle numbers stored instantaneously and automatically in a time series. CONSTITUTION:At a caller, a vehicle number to be called is designated by a key operation beforehand. When plural vehicles are to be called collectively, the key operation is executed in the sequence, and the designation of plural vehicles is executed. Thereafter, when the press for a call channel (s-ch) request is executed, an s-ch request signal is sent, a user code, etc., included in the requesting signal are analyzed by a moving radio center MRC, the identification whether or not a legitimate request is obtained is executed, and at the time of the success, the s-ch is assigned to a caller user. At a calling side to receive the s-ch, after a certain time passes after a carrier rise is '1' automatically, selection call data 2-1-6-2 are collectively sent. These data 2-1 and 2-2, and, 3-1 and 3-2 are respectively the same selection call data and overlapped and sent for improving the channel connection ratio at a radio line. |
