Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless telephone device such as a mobile telephone.

[0002]

2. Description of the Related Art In recent years, research and development have been actively conducted on wireless telephone devices such as mobile telephones. In addition, the mobile phone is shifting from an analog system to a digital system in recent years. In developing the above mobile phone,
It is important to reduce power consumption. This is a mobile phone
This is because electric power is supplied from the built-in storage battery so that the battery can be used as long as possible with one charge.

Most of the power consumption in the call state is consumed in the power amplifier of the transmission circuit. If the power consumption of this power amplifier is reduced, the transmission output will be reduced, so it is difficult to reduce this. On the other hand, the power consumption in the standby state can be reduced by the intermittent reception of call information. The technology for reducing power consumption by intermittently receiving the call information is described in detail in "Standard for Digital Car Phone System (STD-27B)" issued by the Radio Wave System Development Center. , Briefly explained.

The call information is information that is periodically transmitted by the base station in order to notify the mobile telephone under its own station of a call, and the mobile telephone under its control has call information addressed to itself. It constantly monitors whether or not it exists. Wireless communication between a base station and a mobile phone is performed using time-division-multiplexed uplink and downlink control physical channels and uplink and downlink communication physical channels (the period of these physical channels is called a superframe). ). The downlink control channel includes a broadcast channel, a paging channel, an individual cell channel, and a user packet channel, which are time-division multiplexed. Of these, the call information exists in the paging channel.

Since only the call information in the paging channel is intermittently received, the mobile phone generates a timing signal indicating the timing at which the slot of the paging channel appears on the time axis and synchronizes with the timing signal. ,
The above call information is intermittently received. If the intermittent reception is performed in this way, the reception process can be stopped outside the above timing. Therefore, the power consumption can be reduced by the consumption amount of the suspension outside the period, and the usage time per charge can be extended.

[0006]

However, the above-mentioned portable telephone has a problem in that the receiving process is wasted for a long time and the reduction of power consumption is not thorough. This is because the mobile phone waits for reception even in the daytime even during a time period when the call information reception frequency is extremely low, such as midnight or early morning. It is conceivable to turn off the power during such a time period, but then it becomes impossible to receive an emergency call or the like.

Further, according to the technology for reducing power consumption by stopping the receiving process described in the above-mentioned standard, the period during which the receiving process is stopped cannot be set longer,
There is a problem that further reduction of power consumption cannot be expected. In order to reliably send and receive the paging signal, it is necessary to perform the receiving process at the timing of the paging channel. Regardless of this, if the timing of receiving processing is further shortened, reliable transmission / reception of call information cannot be guaranteed.

In view of the above problems, it is an object of the present invention to provide a radiotelephone device capable of further reducing power consumption while ensuring reliable transmission / reception of call information.

<Circuit Configuration of Reception Section Thinning Circuit 22> How the reception section thinning circuit 22 is configured to perform the above thinning will be described. FIG. 3 is a diagram showing basic timing signals before and after thinning, and FIG.
FIG. 3 is a circuit diagram showing a configuration of a reception interval thinning circuit 22 shown in FIG.

In FIG. 3, it can be seen that m pulses exist before and after thinning, and n pulses following the m pulses exist before thinning but do not exist after thinning. . In order to perform such thinning-out processing, the reception section thinning-out circuit 22 changes from the LOW level to the HI level.
The basic timing signal is through-output while m basic timing signals rise to the GH level, and the output signal is LOW while n basic timing signals fall from the HIGH level to the LOW level.

Therefore, as shown in FIG. 4, the reception interval thinning-out circuit 22 compares the (m + n) counter 31 that counts the number of waves of the basic timing signal with the count number c of the (m + n) counter and the above m. If c <m, a HIGH signal is output, and if c ≧ m, a LOW signal is output, and a (m + n) counter 3 is provided.
The AND gate 33 takes the logical product of the output of 1 and the output of the comparator 32.

A process in which the basic timing signal is thinned out by the reception interval thinning-out circuit 22 configured as described above will be described. When the basic timing signal is generated by the basic timing generation circuit 21, the (m + n) counter 31 changes the pulse of the basic timing signal to m +
n pieces are counted. The count number c of the (m + n) counter 31 is compared with the above-mentioned m by the comparator 32, and while c <m, the HIGH signal is output from the comparator 32.
Is output from.

When the HIGH signal is output in this way,
M pulses of the basic timing signal and the comparator 3
An AND gate 33 calculates the logical product of the HIGH signal output from the output terminal 2 and the calculation result is output as an output signal. Therefore, while c <m, all of the above calculation results are HIGH, so that the basic timing signal is output through from the reception interval thinning circuit 22.

While c ≧ m, the LOW signal is output by the comparator 32. When the LOW signal is output in this way, the logical product of m pulses of the basic timing signal and the LOW signal output from the comparator 32 is A.
It is calculated by the ND gate 33. The result of this calculation is
Since it is output as an output signal, the LOW output signal is output from the reception interval thinning circuit 22 while c ≧ m.

<Processing Control in Intermittent Reception Processing of Call Information> Processing control in intermittent reception processing of call information will be described with reference to the flowchart of FIG. (1) Processing when power is turned on When the wireless telephone device is activated by pressing the power switch, the control unit 6 sends the signal of HIGH in all sections to the basic signal so that the receiving system TDMA processing unit 4 always performs a receiving operation. It is generated by the timing generation circuit 21. Further, the changeover switch 23 is changed to the upper side as shown in FIG. At this time, the reception timing control circuit 5 outputs the basic timing signal generated by the basic timing generation circuit 21 as a through output and supplies the basic timing signal to the reception system TDMA processing unit 4. Reception system TD
The MA processing unit 4 always performs reception processing.

FIG. 6A shows a HIGH output signal of the entire section output by the reception timing control circuit 5, and FIG. 6B shows an output supplied from the reception timing control circuit 5 to the reception system TDMA processing section 4 at this time. The signal is illustrated. The signal input unit 2 inputs the second intermediate frequency signal from the antenna,
The second intermediate frequency signal is demodulated by the demodulator 3 using π / 4 shift 4-phase QPSK. From the time-division multiplexed broadcast channel (BCCH) of the demodulated signal, the synchronization acquisition unit searches for a synchronization word, and the wireless telephone device and the base station are synchronized (step S).
1).

After the above series of processing is performed, the speaker
The key punch sets the thinning start time to 22:30 and the thinning stop time to 7:00. With this setting, the RAM 7 already stores the low-frequency reception time zone including these times. Since it is stored in the RAM 7, the low frequency reception time period is shorter, or
Can be set longer.

(2) The timing of the superframe and the paging channel is calculated from the broadcast channel (BCCH) by the processing control calculator outside the low frequency reception time zone (step S2). When the calculation is performed, the signal generation control unit controls the reception timing control circuit 5, and the reception timing control circuit 5 generates a basic timing signal based on the timing of the superframe and the paging channel (PCH). (Step S3).

FIG. 6C shows a reception timing control circuit 5
3 shows an example of a basic timing signal generated by the. The call information is detected from the paging channel (PCH) in synchronization with the basic timing signal, and the detected call information is output to the control unit 6 (step S8). The identifiers of the calling side and the called side in the call information are detected by the identifier detecting section (step S9), and the judging section determines whether or not the detected called side identifier matches the own identifier (step S10). ). When it is determined that they match with each other, the voice output control unit makes a ringing sound, an off-hook operation (call start operation) is performed, and control is performed so that the voice data in the received signal is output as voice (step S11). (3) Switching from outside the low-frequency reception time zone to within the low-frequency reception time zone The time determination circuit 9 determines whether or not the current time measured by the clock unit 8 is the thinning start time. (Step S4).

When it is determined that the thinning-out start time has come, the time determination circuit 9 outputs an instruction signal to the effect that the basic timing signal is thinned out, and the control unit 6 causes the changeover switch 23 to operate. , Reception section thinning circuit 22
To the side (step S5). The changeover switch 23 is changed over to the lower side as shown in FIG. 2, and the signal generated by the basic timing generation circuit is thinned out by the section thinning circuit 22 and output.

In this way, even if the basic timing signal is thinned out, the base station retransmits, so that the call information is almost certainly received. Retransmission means that the base station repeatedly transmits the same information in consideration of the influence of the atmosphere and obstacles such as buildings. On the other hand, when such switching is performed,
The control unit 6 gives an instruction to the display unit 24 so that it can be seen that the data is thinned and received. When the basic timing signal shown in FIG. 6 (d) is thinned out, the basic timing signal becomes as shown in FIG. 6 (e).

(4) Switching from within the low-frequency reception time zone to outside the low-frequency reception time zone It is determined by the time determination circuit 9 whether or not the current time measured by the clock unit 8 is the thinning-out end time. It is determined (step S6). When it is determined that the thinning-out end time has come, the time determination circuit 9 outputs an instruction signal for turning off the thinning-out of the basic timing signal to the control unit 6, and the control unit 6 switches the changeover switch 23 (step S7). The changeover switch 23 is changed to the upper side shown in FIG. 2, and the signal generated by the basic timing generation circuit is directly output as it is.

On the other hand, when such switching is performed,
The control unit 6 causes the display unit 24 to cancel the display of the thinning-out reception. (5) The decimation cancellation radio wave condition determination circuit 10 in the low frequency reception time zone receives the reception level or the normal decoding ratio, and the radio wave condition determination circuit 10 determines whether the value is below a certain level. Is determined, and if the following is true, a prohibition signal for turning off the thinning of the basic timing signal is output to the control unit 6, and the control unit 6 switches the changeover switch 23 (step S7). The changeover switch 23 is changed to the upper side shown in FIG. 2, and the signal generated by the basic timing generation circuit is directly output as it is.

On the other hand, when such switching is performed,
The control unit 6 causes the display unit 24 to cancel the display of the thinning-out reception. Although the embodiments have been described above with reference to the drawings, the present invention is not limited to the embodiments. That is, {1} shown below
There can be aspects of ~ {5}.

The condition for prohibiting thinning out of the {1} basic timing signal may be changed. Further, it may be set not to cancel the thinning even if the radio wave condition changes. In the present embodiment, the thinning circuit is provided as a method of increasing or decreasing the reception section of intermittent reception.
The configuration may be such that m and n can be set and a signal is generated according to the length.

{2} In the above embodiment, the increase / decrease of the reception section is switched between the two states, the basic state and the thinned state. However, the value of the reception level is divided into multiple stages and the thinning rate is set accordingly. Also, the configuration may be set in multiple stages. {3} In the above embodiment, the thinning rate of the reception section is determined,
Although the values of the numbers m and n are set in the thinning control circuit in advance, the values may be set externally. As a setting method, a method of inputting values of m and n with some input device such as a key or selecting from preset thinning rates can be considered.

{4} In the above embodiment, the adjustment of thinning is performed according to a fixed ratio, but the values of the numbers m and n may be randomly generated each time. This is effective in preventing the call information from being unreceivable when the retransmission cycle from the base station is unknown and the retransmission cycle and the thinning cycle overlap. In the {5} embodiment, the increase / decrease of the reception section is adjusted according to the arrival of the start time or the change of the reception situation. However, a mode for thinning and a mode for not thinning are provided and switched. It may be a usable configuration.

In the discontinuous reception method of a radiotelephone device having an antenna, a signal input step of inputting a signal from the base station received by the antenna, and a demodulation step of demodulating received information from the signal input in the signal input step And a basic timing generating step of generating a basic timing signal for receiving the calling information that the base station periodically transmits from the reception information demodulated by the demodulation step, and a value input from an input device such as a key. And a reception timing control step of controlling the reception timing of the call information based on the basic timing signal, Timing control step, in response to the input value, thinning of the reception section from the basic timing signal
By reducing the number of signals based on the values of the numbers m and n that determine the rate , the intermittent reception section is increased or decreased , and
Instruct the display so that you can see that you are thinning out and receiving
Or the values of the numbers m and n are
Discontinuous reception method characterized in that it is generated in the system.
