Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable intermittent reception control system in mobile communication which can reduce power consumption during standby. A mobile device of a mobile communication system generally uses a battery as a power source, and it is necessary to reduce the power consumption of the mobile device in order to prolong the usable time of the battery. Therefore, an intermittent reception method has been proposed in which the receiving unit operates intermittently instead of continuously in order to detect reception of a calling signal during standby. There is a demand for more efficient operation of this discontinuous reception method.

[0002]

2. Description of the Related Art A mobile device of a mobile communication system is, for example,
It has the configuration shown in FIG. In the figure, 4
1, 42 are antennas, 43 is a bandpass filter, 4
4, 54, 51 are mixers, 45, 52, 55 are amplifiers,
46 and 56 are demodulation units, 47 is a switching control unit, 48 is a switching circuit, 49 is a control unit, 50 is a modulation unit, 53 is an antenna duplexer, 57 is a synthesizer, and 58 is a handset unit.

This mobile device shows a case where a diversity system is used, in which the antenna 42 is generally a rod antenna and the antenna 41 is a built-in antenna. The antenna 41, the bandpass filter 43 and the mixer 4 are used.
4, a first reception path including an amplifier 45 and a demodulator 46, an antenna 42, a duplexer 53, a mixer 54, and an amplifier 5
5, the second receiving path including the demodulation section 56 is selected by the switching circuit 48, and the demodulation output signal is added to the control section 49. In that case, the switching control unit 47 controls the switching circuit 48 so as to compare the demodulated output signals of the demodulation units 46 and 56 and select the receiving path with the better reception condition.

The handset unit 58 includes a handset unit, a dial key, a display unit, etc. The demodulation output signal during a call selected by the switching circuit 48 is transmitted via the control unit 49 to the handset unit 58. To the receiver (not shown), and the voice of the other party is reproduced. An output signal corresponding to the voice of a transmitter (not shown) of the transmitter / receiver unit 58 is applied to the modulator 50 via the controller 49, and the modulated output signal is supplied to the mixer 51.
At this time, it is mixed with the output signal from the synthesizer 57 to become a modulated signal of the transmission frequency, amplified by the amplifier 52, added to the antenna 42 via the duplexer 53, and transmitted. The output frequency of the synthesizer 57 is controlled by the control unit 49 so that the synthesizer 57 can perform transmission / reception on the assigned channel.

In a mobile communication system, for example, common information, area information, and incoming information are transmitted in their respective time slots, and the mobile device sends area information and incoming information of a predetermined time slot based on the common information. When the reception operation is continuously performed, the first reception path on the antenna 41 side and the second reception path on the antenna 42 side are received.
The power is always consumed in the two receiving paths including the receiving path of 1). Therefore, in order to reduce the power consumption during standby, various methods have been proposed in which power is intermittently supplied from a power source to perform a reception operation. That is, the control unit 49
For example, the switch circuit (not shown) is controlled by the above, and the operating power supplied to the receiving path is supplied only during the receiving operation.

[0006] For example, the mobile station is divided into a plurality of groups, each group is subdivided into hierarchical groups, and incoming information is transmitted from the base station side in correspondence with the group. A discontinuous reception method is known in which a reception operation is carried out at the timing of transmitting the assigned incoming call information (for example, Japanese Patent Laid-Open No. 2-2828).
24).

The base station notifies the mobile unit of the cell size, and the mobile unit switches the intermittent ratio, which is the ratio of the reception operation time to the standby time, according to the cell size. Are known (for example, Japanese Patent Laid-Open No. 4-3
22523). There is also known an intermittent receiving method in which the intermittent ratio is controlled to be small when the received electric field strength is small (see, for example, Japanese Patent Laid-Open No. 4-345330).

[0008]

DISCLOSURE OF THE INVENTION Problems to be solved by the invention: By performing the intermittent reception as described above when the mobile station is in standby, the consumption of the battery of the power source is reduced and the standby time is extended as compared with the case of performing continuous reception. You can When the number of incoming calls is close to zero, such as at night, the power switch is turned off to prevent the battery of the power source from being consumed. In this case, if the power switch is forgotten to be turned off, the battery of the power source will be uselessly consumed because the intermittent reception is performed even in the time zone when there is almost no incoming call such as at night. Also, the next morning, I forget to turn on the power switch, and sometimes I do not notice the call operation. In this case, there is a problem that the call cannot be made with the caller because the incoming call cannot be detected until the user notices. That is, when operating the power switch in order to reduce the consumption of the power source battery, forgetting to turn it off or forgetting to turn it on becomes a problem, and the operability of the mobile device is not always easy. An object of the present invention is to reduce the consumption of the battery of the power source by automatically switching the intermittent ratio between the time zone when an incoming call is expected and the time zone other than that.

[0009]

A variable intermittent reception control method in mobile communication according to the present invention will be described with reference to FIG. 1. The mobile device 1 performs a receiving operation with a radio transmitting / receiving section 2 in an operating state. A reception timing generation unit 3 for generating a reception timing signal for setting, a memory unit 4 for storing a scheduled use time, a clock unit 5, an input unit 6 for inputting a scheduled use time to be stored in the memory unit 4, and each unit. When the time information of the clock unit 5 indicates the scheduled use time stored in the memory unit 4, the control unit 7 controls the reception timing generation unit so that the intermittent reception ratio becomes large. Control 3 Reference numeral 8 is a transmission / reception processing unit including a handset and the like.

Further, it is possible to receive the time notification or the intermittent reception ratio control information via the radio base station and control the reception timing generation unit 3 for performing the intermittent reception.

[0011]

Operation: For example, a time at which an incoming call is expected is input as the scheduled use time from the input unit 6 and stored in the memory unit 4. Further, the time when the incoming call becomes almost zero, such as at night, is input as the non-use scheduled time and stored in the memory unit 4. The control unit 7 compares the time information from the clock unit 5 with the time information stored in the memory unit 4, and when they match, controls the reception timing generation unit 3 to switch the generation cycle of the reception timing signal.
For example, when the time information of the clock unit 5 indicates the scheduled use time stored in the memory unit 4, the control unit 7 controls the reception timing generation unit 3 to shorten the generation cycle of the reception timing signal. As a result, the intermittent ratio becomes large, and incoming information can be detected quickly. When the time information of the clock unit 5 indicates the scheduled non-use time stored in the memory unit 4, the control unit 7 controls the reception timing generation unit 3 to lengthen the generation cycle of the reception timing signal. As a result, the intermittent ratio can be reduced, and the consumption of the battery of the power source can be reduced. In this case, by changing the intermittent ratio stepwise, the intermittent ratio at night or the like can be set to a value close to zero.

Further, instead of using the time information of the clock unit 5,
Time information from the wireless base station can be used. Further, instead of the scheduled use time stored in the memory unit 4, the intermittent reception ratio control information from the wireless base station can be used. In any case, without operating the power switch,
The intermittent ratio can be changed automatically.

FIG. 3 is a diagram for explaining the operation of the embodiment of the present invention, in which (a), (e) and (i) are transmission signals from the base station,
(B), (f), (j) are reception timings, (c),
(G) and (k) show the reception timing of the common information F and the area information B _i, and (d), (h) and (l) show the reception timing of the incoming information P _j . This operation explanatory diagram shows the number of areas i
= 3 (area information B ₁ .about.B _3), shows a case where incoming group number j = 4 for (incoming information P ₁ ~P _4).

In the case of the reception timing shown in FIG. 3B,
It is composed of the reception timing of the common information F and the area information B _{1 in} (c) and the reception timing of the incoming information P ₃ and P _{4 in} (d). The reception timing of the area information B ₁ and the incoming information P ₃ , P ₄ is determined, and the intermittent reception is performed at the reception timing of (b). This case corresponds to the case where the intermittent ratio is large.

In the case of the reception timing shown in FIG. 3 (f),
By receiving and identifying the common information F, the area information B ₁
And the incoming call information P ₃ , P ₄ , and receives the next incoming call information P ₃ ,
The case where the reception of P ₄ , common information F, and area information B ₁ is stopped is shown, and the intermittent ratio is reduced by thinning out the incoming information P ₃ , P ₄ , common information F, and area information B _1. . The intermittent ratio can be further reduced by increasing the number of times of thinning.

In the case of the reception timing shown in FIG. 3 (i),
By receiving and identifying the common information F, the area information B ₁
And the incoming call information P ₃ , P ₄ , and receives the next incoming call information P ₃ ,
The case where the reception of P ₄ and area information B ₁ is stopped is shown.
By thinning out and the area information B ₁ incoming information P _3, P _4, which was to reduce the intermittent ratio is larger than intermittent ratio as compared to the reception timing of (f).

For example, the reception timing shown in (b) of FIG. 3 is set as the intermittent reception timing after the scheduled use time when the incoming call is expected, and the non-use scheduled time is as shown in (f) and (j). , Can be thinned to reduce the intermittent ratio, or the intermittent ratio can be set to zero until the next scheduled use time. It is also possible to switch the intermittent ratio to multiple stages instead of two stages. For example, when approaching the scheduled use time, gradually increase the intermittence ratio, and after the scheduled use time, register the time zone in which it is expected that the frequency of incoming calls will increase, in the same way as the scheduled use time. It is also possible to control so that the intermittent ratio in the band is further increased.

FIG. 4 is an explanatory diagram of time collation according to the embodiment of the present invention, showing a case where the intermittent ratio is switched in multiple stages. The intermittent ratio is registered in the memory unit 34 in a 2-bit configuration, and the designated time is set to 2.
Shown is the case of registration in a 4-hour system. Although the timepiece unit 35 is shown in an analog form, it can be a digital timepiece having various known structures. The collation unit 32 can be realized by the collation determination function of the processor 11 or the sub processor 17, and collates the time information of the clock unit 35 with the designated time information registered in the memory unit 34 to receive the reception timing generation unit 33. It controls the cycle of the reception timing signal from.

The intermittent ratio is, for example, "00" is zero and "1".
"1" is an intermittent ratio as shown in FIG. 3B, "01" is an intermittent ratio in which the number of times of thinning in FIG.
0 "can be set to the intermittent ratio as shown in FIG. 3 (j). Further, the contents registered in the memory unit 34 are the intermittent ratio" 10 "from 7 o'clock and the largest intermittent ratio" 11 "from 10 o'clock. ",
It shows the case where the intermittent ratio is “01” from 12:00, the largest intermittent ratio is “11” from 13:00, and the minimum intermittent ratio is “00” from 20:00. The scheduled use time is 7:00 and the scheduled nonuse time is 2
This corresponds to the case of 0 o'clock.

Under the control of the processor 11 or the sub-processor 17 in FIG. 2, the current time information is compared with the registered scheduled use time or scheduled unused time. As described above, when the time is specified in the memory unit 34 together with the intermittent ratio, when the time information of the clock unit 35 indicates 7:00, it coincides with the registered designated time of 7:00 in the memory unit 34. The ratio “10” is the reception timing generation unit 3
Set to 3.

Therefore, the reception timing signal from the reception timing generation unit 33 is applied to the radio transmission / reception unit 2 of FIG. 1, for example, in a cycle according to the set intermittent ratio "10". In that case, for example, as shown in (j) of FIG. 3, after receiving the common information F, the area information B ₁ , thinning out a predetermined number of times, and receiving the incoming information P ₃ , P ₄ , Intermittent reception can be performed by thinning out the number of times less than the area information B ₁ .

When the time information of the clock unit 35 indicates 10:00, it coincides with the registered designated time of 10:00, so that the intermittent ratio "11" at that time is set in the reception timing generation unit 33. As a result, a reception timing signal for receiving the common information F, the area information B _1, and the incoming information P ₃ , P ₄ from the reception timing generator 33, as shown in FIG. 3B, for example. Is generated, the receiving unit of the wireless transmission / reception unit
The reception operation is performed according to the reception timing signal having the maximum intermittent ratio. In this case, since the incoming call frequency is expected to be high, the intermittent ratio is increased.

Further, when the time information of the clock section 35 indicates 12:00, it coincides with the registered designated time of 12:00, so that the intermittent ratio "01" at that time is set in the reception timing generation section 33. As a result, the reception timing signal is generated from the reception timing generation unit 33, for example, with an intermittent ratio in which the number of thinning-outs in (f) of FIG. 3 is further increased. Also clock section 35
When the time information of 1 indicates 13:00, it coincides with the registration designated time of 13:00, so that the intermittent ratio "11" at that time is set in the reception timing generation unit 33. That is, from 12:00 to 13:00 is the time for lunch break, which is a time zone in which the frequency of incoming calls is expected to be low, so the intermittent ratio is reduced.

Since the time period after 13:00 is expected to be high in the frequency of incoming calls, the case where the intermittent ratio is set to a large value is shown. Next, when the time information of the clock unit 35 indicates 20:00, the registered designated time Since it coincides with 20:00, the intermittent ratio "0" at that time
0 "is set in the reception timing generation unit 33. That is,
At 20:00, the scheduled non-use time is shown, and the intermittent ratio "00" shows the minimum intermittent ratio or the intermittent ratio of zero. Therefore, the intermittent ratio automatically becomes the minimum or zero during the designated time from 20:00 to 7:00, and the consumption of the battery of the power source can be reduced without operating the power switch of the mobile device. Alternatively, it is possible to perform control corresponding to the case where the timer 14 of FIG. 2 is set to a time interval of 11 hours from 20:00.
In that case, since the reception timing signal is not output until 7 o'clock, the intermittent ratio during that period becomes zero.

As described above, when switching the intermittent ratio in multiple stages, it is possible to gradually change the intermittent ratio before and after each designated time. Further, even during a time period in which the intermittent ratio is controlled to be small by the registered designated time, it is possible to perform control so as to return to the normal intermittent ratio by an interrupt from the keyboard input. It is also possible to switch to increase the intermittent ratio by inputting the setting cancellation. For example, even if the intermittent ratio is automatically switched to the minimum or zero at night, the setting is canceled when an incoming call is expected, and the intermittent ratio is set to “10”, for example. Can be set.

Further, a system for periodically reporting time information from the base station on the control channel can be constructed. In that case, the time of the clock unit 20 is received by the control of the processor 11 and the sub-processor 17. It can be corrected by the time information. Further, in the configuration in which the clock unit 20 is not provided in the mobile device, the intermittent ratio can be switched based on the time information from the base station by collating with the designated time registered in the memory unit 34.

Further, by registering the scheduled use time and the like corresponding to the mobile station in the mobile communication system, the mobile station is designated from the base station via the control channel, and the intermittent ratio is registered at the registered scheduled use time. The switching information of can be transmitted. In that case, since the mobile device switches the intermittent ratio based on the intermittent ratio switching information from the base station, without operating the power switch, for example, at night, etc. By setting it to zero, it is possible to reduce the consumption of the battery of the power supply. Further, according to the present invention, it is possible to add means for switching the intermittent ratio according to various conditions of the cell in which the mobile device is located.

[0035]

As described above, according to the present invention, the time zone in which an incoming call is expected is registered in advance, and the incoming call is predicted by checking the registered designated time and the current time information. Increase the intermittent ratio of the time zone to be set, conversely, reduce the intermittent ratio of the time zone such as night when the probability of incoming calls is small or zero, without operating the power switch,
It is possible to automatically reduce the battery consumption of the power supply. Therefore, there is no problem of forgetting to turn off the power switch or forgetting to turn it on, and there is an advantage that the operability of the mobile device is improved.
