PROBLEM TO BE SOLVED: To transfer the same message contents to plural hand sets without troubling a transmitter by preserving data, which are to be reported to the other hand sets, in a memory and automatically originating a call to the other hand sets at any arbitrary time point when directly performing talking between hand sets without interposing a base unit. SOLUTION: Based on initialize data previously stored in a memory 1, the entire system is initialized according to the command of CPU 10. Next, when the hand set is set in a transceiver (inter-hand set direct speaking) mode, transmission data such as voice mail or message are registered. After that registration is completed, the hand set starts a call termination control sequence to the first hand set on a transmission destination list, which is previously stored in a memory 11, showing the order of transmission destinations for the voice mail or message. When the call origination/termination control sequence is made successful, its time is stamped in the memory 11. Afterwards, the hand set, for which the call origination/termination control sequence is made successful, is excluded from the transmission destination list stored in the memory 11. |
