平２−２３７２３１号公報に開示されている。2. Description of the Related Art Mobile telephones monitor the status of neighboring base stations and select the most suitable base station for communication. If the radio signal from the base station to the mobile phone is called a downlink signal, this most suitable base station is generally
The base station has the highest reception level of the downlink signal. This conventional example is disclosed in, for example, JP-A-2-126738 and JP-A-2-237231.
【０００３】このような移動電話機における周辺基地局
の状態の監視動作は、実際に通信を行っていない待ち受
け時にも行われており、発信時または着信時に、即座に
対応できるようになっている。Such a monitoring operation of the state of the peripheral base station in the mobile telephone is carried out even in a standby state in which communication is not actually carried out, and it is possible to immediately respond to a call or a call.

信周期の長さを変更し、できるだけ受信時間を減らすこ
とにより、移動電話機の電源使用時間を短くしている。In the standby operation of the conventional mobile telephone, the power supply usage time of the mobile telephone is shortened by intermittently receiving the downlink signal from the base station. For example, Japanese Patent Application Laid-Open No. 2
000-332680 and JP-A-2000-29
In Japanese Patent Publication No. 9885, the length of a reception cycle in standby is changed according to the reception level, and the reception time is reduced as much as possible to shorten the power supply usage time of the mobile phone.

しまう。In such a conventional technique, the state search of the peripheral base stations in the intermittent standby is performed without recognizing the stationary or moving state of the mobile telephone.
Therefore, even when the mobile telephone is in a stationary state, a base station most suitable for communication is selected, and a standby state is waiting for the base station, the state search of neighboring base stations is unnecessarily performed.

A technique for avoiding repeating state transitions is disclosed. However, the official gazette does not specify the purpose of saving the battery while the mobile phone is in the service area.

When it is determined that the mobile station is in a stationary state, the downlink signal reception of the peripheral base station is temporarily stopped or the cycle of the downlink signal reception is extended to reduce the standby reception time and reduce the power consumption. The purpose is to provide the program.

If a mobile station is in a stationary state when a base station that can be a good communication partner is already selected in the area, it is not necessary to search for a base station that can be a communication partner in addition to the base station. In this case, the search time is temporarily stopped or the search cycle is extended to shorten the reception time and save the power required for reception.

辺監視状態（Ｓｔｅｐ７）に辿り着くことになる。Next, the operation of the mobile telephone according to the embodiment of the present invention will be described in detail with reference to FIGS. In FIG. 2, the operation during the intermittent standby will be described. During the intermittent standby (Step 1), the movement of the mobile telephone itself is detected (Step 2). According to the detection result, it is determined whether the vehicle is moving or stationary (Step 3). If the vehicle is moving, the peripheral monitoring is continuously performed (Step 3).
8) If it is stationary, it is judged whether or not to change the peripheral monitoring operation and proceed to the step of deciding the operation (Step).
3). When the mobile station is not moving, the peripheral base stations are monitored again (Step 4), and it is determined whether or not the current standby base station needs to be changed according to the monitoring result (S4).
step 5). If it is not necessary to change the standby base station because the current downlink signal from the standby base station can be received most favorably as compared with the downlink signals from other base stations (S
(Step 5), the surrounding base stations are not monitored or the monitoring cycle is extended (Step 6), and the stationary peripheral monitoring state is set (Step 7). If the downlink signal from another base station can be received better than the downlink signal from the current standby base station, it is judged that the standby base station needs to be changed (Step 5), and the intermittent standby state is continued. As a result, the base station that can best receive the downlink signal is selected (Step 9). In this way, finally, the base station that can best receive the downlink signal is selected, and if the mobile telephone is stationary, in the next cycle, it will reach the stationary peripheral monitoring state (Step 7). .

効果も得ることができる。In this way, the stationary mobile telephone monitors the downlink signals of the peripheral base stations other than the standby state, for example, at a monitoring cycle which is several times as long as the mobile state, or until the mobile telephone becomes the mobile state. To prevent power consumption during the standby time. This operation can be performed without the user's knowledge. Further, it is possible to obtain the effect of reducing unnecessary zone shifts in a place where the reception level is unstable.

The current movement status of the mobile phone is detected (Step 1
1), a judgment is made according to the state detected here (St
If it is determined that it is not moving, it is determined again whether or not the peripheral monitoring while stationary is allowed (Step 13).
In this determination, if it is determined that the current standby base station is the most suitable base station for communication, it is determined that the surrounding base stations are not monitored or the monitoring cycle is extended (Step 14) and the station is stationary. Continue monitoring around (St
ep15). Further, the current moving state of the mobile telephone is detected (Step 11), and if it is moving (Step 1)
2) Stop the peripheral monitoring while stationary and shift to the intermittent standby state (Step 16). Even when the mobile phone is not moving (Step 12), an obstacle such as a parked vehicle appears between the mobile phone and the base station, which deteriorates the current downlink signal reception state of the standby base station and the surrounding area. When it is determined that base station monitoring is necessary (Step 1
3) Then, the operation shifts to the intermittent waiting state (Step 17).

Even when the mobile telephone 27 is in a stationary state and is in a standby state while receiving a downlink signal from the base station 24, the surrounding base stations 25 and 26 can naturally be monitored because they are also in the area, but the mobile telephone 27 is denoted by 27.
