PURPOSE:To execute an information service without using a station control channel C-CH dedicated for a radio channel control station MCS or a communication channel group S-CH dedicated for an exchange station AMS by providing a means to identify an information service requesting code and an in-zone zone number included in a call signal from a mobile machine at a radio base station. CONSTITUTION:The radio base stations RZ1-RZ3 receiving the call signals identify the in-zone zone numbers, respectively, and the processing of the call signal is started at the radio base station PZ2 where the signal coincides with the in-zone zone number. The information service requesting code included in the call signal is identified, and a control part CONT establishes a radio channel between the mobile machine MMS-D and a transmitter/receiver VTRX 6 for the call by a call connection control function, and connects a communication channel V-CH6 to an information service line INF-CH2, and also, and outputs service information INF-B out of a service information group held by a service information offering part SINF by controlling it. |
