本発明は、着呼信号に対する着呼応答信号の送
信制御に関し、特に自動車電話移動局の着呼応答
信号送信方式に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to transmission control of an incoming call response signal in response to an incoming call signal, and more particularly to an incoming call response signal transmission system for a mobile phone mobile station.

の周波数シンセサイザの電源は制御チヤンネルに
いる間はオンにしておかなければならない。(Prior Art) Conventionally, this type of mobile station usually does not have a means to independently control the power supply of the frequency synthesizer in the transmission system.
The power remained on even while waiting for an incoming call signal on the control channel. Furthermore, even if such control means were available, the time between an incoming call signal and its corresponding incoming call response signal would be shorter than the time it takes for the frequency synthesizer to stabilize after turning on the power. If the received signal is determined to be an incoming call signal, even if the transmitting system's frequency synthesizer is turned on, the incoming call response signal cannot be transmitted after the specified time, so the transmitting system's frequency synthesizer must be turned on while on the control channel.

う欠点があつた。(Problem to be Solved by the Invention) Therefore, in the above-mentioned conventional mobile station, even though no signal is transmitted, the power of the frequency synthesizer in the transmission system remains on, resulting in wasted power. It has the disadvantage of being consuming. In addition, frequency synthesizers usually require a high-speed counter/prescaler, and the power consumption during operation is a non-negligible value compared to the power consumption of the entire device, so portable devices that use batteries as a power source cannot The drawback was that the operating time was limited to some extent.

る方式である。(Means for Solving the Problems) The incoming call response signaling system of the present invention uses a timer to control the power supply of the frequency synthesizer in the transmitting system, starts the timer when a frame synchronization signal of the received signal is detected, and sets the timer to After counting the time, turn on the power to the frequency synthesizer in the transmitting system, and if the received signal is not an incoming call signal, turn off the power to the frequency synthesizer in the transmitting system, and if it is an incoming call signal, it will output an incoming call response signal after a certain period of time. This method starts the transmission of the data.

Further, if the signal following the detected frame synchronization signal is an incoming call signal (Page), the control unit 8 keeps the transmitting frequency synthesizer 5 powered on and transmits the control line at a predetermined time from the incoming call signal. 14 to turn on the power amplifying section 7 and start transmitting an incoming call response signal (Respones) to the base station. A timing chart of this operation is shown in FIG. In this figure, the time T s from when the transmitter synthesizer 5 is powered on until the power amplifier 7 is powered on is the time T s from when the transmitter frequency synthesizer 5 is powered on and the frequency is specified, until the frequency is stabilized. The set time T t of the timer 18 is determined so that it is longer than the time until the end. In this way, radio waves with a stable frequency can be transmitted after the predetermined call response time T d .
