PROBLEM TO BE SOLVED: To improve the utilizing efficiency of a radio wave in multi-cast service by providing an automatic selection function (agent function) of information based on optional designation by the user to a called party radio terminal equipment. SOLUTION: A network is made up of an information service center 1, a communication center 2 consisting of a base station 4 and a communication control center 3, a caller radio terminal equipment 5 and a called radio terminal equipment 6. Then the called radio terminal equipment 6 compares and discriminates identification information of a multiple address message sent from the communication center 2 with multiple address identification information stored in a memory in advance, and when discrimination result indicates coincidence, the reception message is stored in the memory and informed to the user. Furthermore, the user enters a reply message in response to a received message and a reply message and a terminal ID of its own station are added to the transmission message and the resulting message is sent to the communication center 2 for the transmission toward the radio terminal 6 making a transmission call. |
