[0002]
[Prior art]
FIG. 3 is a block diagram showing a conventional digital mobile phone device. In FIG. 3, reference numeral 1 denotes an antenna for receiving a radio wave from a base station, and 2 denotes a data receiving / processing unit for digitally processing data received via the antenna 1. (IF), comprises a radio unit 3 for converting to a low-frequency signal and demodulating it, and a receiving unit 4 for performing digital signal processing such as TDMA processing on the output of the radio unit 3. Reference numeral 5 denotes an intermittent reception timer that measures an intermittent reception interval during standby, and reference numeral 6 denotes a microprocessor (CPU) that controls the operation of the reception data processing unit 2 based on the output of the intermittent reception timer 5.
[0003]
The operation of the digital cellular phone configured as described above will be described below. When the digital mobile phone starts standby reception, the operation of the reception unit 4 of the data reception / processing unit 2 is stopped by the control of the CPU 6 and the wireless unit 3 is controlled by the CPU 6 in order to reduce power consumption during standby reception. Turn off the power. Further, the intermittent reception interval is set in the intermittent reception timer 5, and after the intermittent reception timer 5 is started, the operation of the CPU 6 itself is stopped and the apparatus enters the standby reception state.
[0004]
When the intermittent reception timer 5 reaches a set time after entering the standby reception state, the intermittent reception timer 5 outputs an interrupt signal, and the CPU 6 is activated by the interrupt. After the activation of the CPU 6, the power of the wireless unit 3 is turned on under the control of the CPU 6, and the operation of the receiving unit 4 is started.
[0005]
The reception data received by the antenna 1 is sequentially converted from a high-frequency signal to an intermediate-frequency signal and a low-frequency signal by the radio unit 3 and then demodulated. The demodulated data is further transmitted to the reception unit 4 and subjected to digital processing such as amplification and TDMA processing. Signal processing is performed. The received data processed by the receiving unit 4 is sent to the CPU 6. The CPU 6 analyzes whether or not the own terminal is called based on the received data. As a result of the analysis, if the own terminal has been called, the process proceeds to a call process. If the own terminal has not been called, the operation of the receiving unit 4 is stopped under the control of the CPU 6 and the The power of the unit 3 is turned off. Further, after setting the standby reception interval in the intermittent reception timer 5 and activating the intermittent reception timer 5, the operation of the CPU 6 itself is stopped, and the operation returns to the standby reception operation again.
[0006]
[Problems to be solved by the invention]
However, in the conventional configuration, since the CPU 6 performs the operation control of the data receiving / processing unit 2, that is, the power control of the radio unit 3, the activation control of the receiving unit 4, and the analysis of the received data, Even when the own terminal is not called, the CPU 6 must be maintained in the operating state, and as a result, there is a problem that the power consumption during standby reception increases.
[0007]
SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and an object of the present invention is to realize a digital mobile phone device capable of reducing power consumption during standby reception.
[0008]
[Means for Solving the Problems]
In order to solve this problem, a digital mobile phone device of the present invention includes a data reception / processing unit that receives data transmitted from a base station and performs digital processing on the data, and a reception data obtained through the data reception / processing unit.

With this configuration, the reception control unit controls the start / stop of the data reception processing / processing unit and the data analysis unit at regular intervals to detect a call from the transmission terminal, thereby enabling standby reception without activating the microprocessor. And power consumption during standby reception can be reduced.
[0010]
Further, the reception control unit, upon receiving the interrupt signal and receiving the call in a state where the data reception / processing unit and the data analysis unit are activated, performs a call process under the control of the microprocessor. When the call is not received, the data receiving / processing unit and the data analyzing unit are stopped.
[0011]
With this configuration, the reception control unit activates the data reception / processing unit and the data analysis unit when the time set by the intermittent reception timer has elapsed in the standby reception state, and receives data and performs necessary digital processing and data analysis. And activates the microprocessor only when the terminal itself is receiving a call to enable transition to call processing.When the terminal is not called, without activating the microprocessor, the data reception / processing is performed. Unit and the data analysis unit are stopped, and standby reception is started again. When the terminal is not receiving a call, standby reception can be performed without activating the microprocessor, and power consumption during standby reception can be performed. Can be reduced.
