PROBLEM TO BE SOLVED: To attain the proper originating/incoming operations of plural identifiers with no increase in cost by storing the identifiers of plural telephone numbers, etc., and controlling communication, according to the result of collation that is obtained between a telephone number and an identifier which are related to communication. SOLUTION: When a user of a portable telephone system 1 turns on a power supply of the system 1, an incoming control part 2a starts its operation to start the receiving of a perch channel. A queuing state is set, after the perch channel is received. When an incoming signal is received at a radio part 5, the incoming signal is fetched and then the identifier of the incoming signal is collated with an identifier that is stores in a storage 6. When both identifiers match each other, the incoming processing is carried out. When no match is confirmed between both identifiers, it goes to a queuing state. Thus, it is possible to perform plural incoming operations, by storing plural identifiers in the storage 6, collating a received identifier in a reception mode of the incoming signal with the identifier of the storage 6 at an identifier collation part and performing the incoming control, depending on the result of collation of both identifiers.
