PROBLEM TO BE SOLVED: To correctly perform caller number display or the like to a terminal equipment connected to a slave station side by transmitting caller information entered from an exchange to a master station to a slave station in a system for which the master station and the slave station are connected by a radio channel. SOLUTION: Upon receiving CND data between ringing signals from the exchange, a base station tentatively stores them and transmits a PAGE message to the slave station. The slave station 3 receives the PAGE message, transmits first ringing signals to an object telephone set and returns a PAGE RSP message to the base station. The base station which receives the PAGE RSP message uses a communication path established at the timing and transmits the previously stored CND data to the slave station. The slave station which receives the CND data transmits the CND data to the object telephone set, executes the caller number display on the telephone set and then, transmits second ringing signals.
