The present invention provides a system capable of individually controlling each of receiving devices while making full use of the advantages of broadcasting. Simultaneous transmission is carried out from a broadcasting deviceto a plurality of receiving devicesvia a broadcasting path. Further, the broadcasting devicesends operation control data to the receiving devicethrough a communication path. The receiving devicechanges its operation in accordance with the operation control data when received broadcasting is decoded. In this way, each of the receiver devicescan be controlled individually using the operation control data while making full use of the advantages of broadcasting.

Electronic mail system

A radio pager system includes a radio pager that can receive messages and can specify a specific output mode, including a display, a sound output, a vibration, and a light emission appropriate to a particular type of message. The radio pager can further reduce difficulties in retransmitting and/or replying to messages and save time in the transmission period. The radio pager can receive and implement a radio message that includes control information which can be utilized for generating the specific output mode of the display.

Radio-calling device capable of setting flexibly output mode

In order to detect a base station for a call connect or handover in almost real time while a mobile communication apparatus is moving, the measured base station selecting unit 110 refers to the measured base station table 101 and selects a next base station to be measured. The measuring unit 111 measures the signal quality for the selected base station. The measuring result judging unit 112 compares the measured signal quality with a predetermined threshold and judges whether the measurement of the signal quality of the present base station should be continued or whether a switch to measuring a next base station should be performed. The periphery base station table updating unit 113 rearranges the content of the periphery base station table 102 in descending order of signal quality, based on the information stored in the periphery base station table 102 and on the averages of the signal quality measurements.
