Abstract

PURPOSE:To reduce power consumption without performing useless communication by stopping communication from the mobile radio equipment to a base station when it is detected that a communication line between the base station and the mobile radio equipment performs unidirectional communication. CONSTITUTION:A unidirectional communication detection circuit 4-1 is formed by a storage circuit 6 for storing plural telephone numbers for one-sided communication and a comparator circuit 7 for comparing the telephone number to be inputted at the time of originating a call with the telephone numbers stored in the storage circuit 6. The telephone number inputted at the time of originating the call from a mobile radio equipment 2 is compared with the telephone numbers stored in the circuit 6 by the comparator circuit 7. When the coincident number exists, the communication line is opened, and the radio equipment 2 stops transmission later by a transmission control circuit 5 and only receives information signals from a base station 1. When it is necessary to receive a control signal from the radio equipment 2, only the control signal is transmitted. Thus, energy consumption is reduced by preventing unwanted communication from being performed, and the service life of a battery is prolonged.

機の電力を無駄に消費する欠点があった。The conventional mobile radio set described above has the following drawbacks and problems. The car telephone system is generally bidirectional simultaneous communication. However, telecommunications carriers also provide one-way communication services such as hourly reports, weather forecasts, and news notification services for the convenience of subscribers. When a subscriber receives such a service, he / she receives only and does not need to send. However, in the conventional mobile radio device used in the car telephone system, in this case as well, the receiver as well as the transmitter continues to operate, and noise information is wastefully transmitted to the base station. Therefore, there is a drawback that the power of the mobile wireless device is wasted.

Then, it becomes possible to detect easily.
In the embodiment for inserting the one-way communication information in this information signal,
The transmission restriction effectively operates even in communication that is not known to be one-way communication. For example, when an individual business operator independently provides an information providing service such as the market price of stocks, the network side cannot know in advance that the communication is one-way communication. Therefore, in this case, as shown in this embodiment, the transmission can be restricted by providing a circuit for detecting the one-way communication from the received information signal, and the power consumption can be reduced.
