Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paging mobile telephone system for position registration when moving between a plurality of wireless service areas.

[0002]

2. Description of the Related Art Conventionally, a mobile phone in a mobile phone system performs intermittent reception. In this intermittent reception, individual information from the wireless base station (in the text, described as ID if necessary) is monitored, and when an ID of a different wireless base station is detected, the wireless base station of this ID is accessed, I am registering my location.

By the way, in the mobile telephone system, the service area of one radio base station is approximately 3 km. In addition, the service area when the whip antenna is stored in the mobile phone is about 1 km.

[0004] In addition, in a mobile phone, batteries of different shapes with different capacities are mounted and used. For example, a thin battery has 8 hours of standby reception when charging is completed, and 15 to 15 calls are possible. It has a capacity of 20 minutes.

[0005]

As described above, in the conventional mobile telephone system, when the whip antenna is stored in the mobile telephone, the service area is about 1 km. In the movement of the mobile phone passing through such a narrow service area, since the ID of the wireless base station is detected for each service area, the number of position registrations increases. Therefore, there is a drawback that access transmission for self-location registration occurs frequently and the battery current consumption increases. The present invention is
An object of the present invention is to provide an excellent paging mobile phone capable of receiving a call from a wireless base station by a wireless call receiver, reducing the number of position registrations, and reducing battery current consumption.

[0006]

To achieve this object, the present invention comprises an automobile switching center, a mobile telephone terminal device, a radio call terminal device, a mobile telephone radio base station, and a radio call transmitting station. A paging mobile phone system having a wireless base station facility and a paging mobile phone, the paging mobile phone is a wireless call receiving unit that always operates according to a predetermined process, and a wireless phone that is always in a sleep state during standby. The paging mobile phone includes a transceiver unit, an interface unit that processes operations between the radio call reception unit and the radio telephone transceiver unit, and a power supply battery. The standby reception detecting means for detecting and other predetermined wireless paging channel when reception is impossible are searched to find the best Channel detecting means for detecting the channel, and comparing means for comparing the channel number detected by the best channel detecting means with the stored channel number immediately before switching, and if the result of the comparison indicates that they are different, the radiotelephone transceiver is operated. P channel search means for searching for P channel by means of transmitting, transmitting means for searching for P channel and transmitting on a channel having a good receiving state, and position registering means for transmitting position on the channel having a good receiving state from the transmitting means and performing position registration. It is a thing.

[0007]

Therefore, according to the paging mobile telephone system of the present invention, it is necessary to register the position while the call of the radio base station is received by the radio call receiving unit and the mobile phone moves in a wide area and is located in the radio call service area. However, since the location registration is performed when the user moves out of one wireless calling area and detects a movement to another area, the number of location registrations can be reduced and battery current consumption can be reduced.
