PURPOSE:To call an opposite party even when the group number of a call station is not known by storing the group number of a station to be called as well by the call station as its own waiting group number only for fixed time after finishing communication, and using its own group number as a call originating group number by the station to be called. CONSTITUTION:For example, a radio station A (call station) calls a radio station E (station to be called) by a group number '55555' and makes a call. Assuming that after the lapse of continuous call enable time for one minute, the call is finished, when the station E to be called desires the restart of the call with the call station A just after finishing this call, only for 10 seconds, for example, after the end of the speech, the radio equipment of the call station A stores the group number '55555' of the station E to be called into a memory as its own waiting group number. Therefore, when the station E to be called uses its own group number '55555' as the call originating group number only for these 10 seconds, the station E to be called can restart the call even when the original group number ('1111') of the call station A is not known. |
