In FIG. 3, reference numeral 31 is a main unit having a position management function, and 321 to 325 are base stations connected to the main unit 31. Of these base stations, the base stations 321 to 321 are shown.
323 is grouped into a first group, and base stations 324 and 325 are grouped into a second group. Reference numeral 33 denotes a slave unit (mobile station) which is connected to the base stations divided into groups by telephone communication.

In the system cordless telephone configured as described above, for example, when the mobile device 33 moves from the second group to the wireless zone of the second group, a wireless channel is set with the base station 323 at that time. Then, the main device 31 is notified of the information including the terminal identification number via the base station 323. The main device 31 notifies all the base stations 321 to 323 in the first group of an incoming call signal for calling the slave unit 33 when the slave unit 33 receives an incoming call, and also in the first group. In all the base stations 321 to 323 of the slave unit 3
By sending an incoming call signal to the mobile phone 3, the mobile phone 33 is notified of the incoming call.

As described above, even in the above-mentioned conventional system cordless telephone, the position of the slave unit can be grasped and the incoming call can be notified to the slave unit.

[0007]

However, in the conventional position management device as described above, since the base stations are divided into groups, the main device determines which base station the slave unit is waiting for. It cannot be identified and is unsuitable for manlocation. In addition, since the wireless channel is set every time the slave unit registers its location, the channel for a call of another slave unit may be temporarily blocked, and there is a problem that wireless usage efficiency decreases. Furthermore, since the main unit must notify the incoming call signal to all the base stations in the group each time there is an incoming call to one child device,
There was a problem that the system traffic would be high.

The present invention is intended to solve the above-mentioned problems, and the location of a system cordless telephone which can improve the radio use efficiency and the system traffic by performing location management of a mobile station (slave unit) on a base station basis. The purpose is to provide a management device.

[0009]

In order to solve the above-mentioned problems, the present invention uses an uplink control channel to move each time a mobile station moves to a radio zone created by any one of the plurality of base stations. A burst signal including a station identification number is transmitted to the movement-destination base station once or a plurality of times, and the movement-destination base station that has received this burst signal notifies the main apparatus of a position registration signal based on the identification number. By doing so, the main device is characterized in that it can identify in which base station the mobile station is located in the radio zone.

With this, the location management of the mobile station can be performed in base station units, and the radio use efficiency and the system traffic can be improved.

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention has a plurality of base stations connected to a main device having a location management function, and a mobile station connected to each of the base stations for communication. A location management device for a system cordless telephone, wherein a burst signal including an identification number of a mobile station is moved by an uplink control channel every time the mobile station moves to a radio zone created by any one of the base stations. The main device notifies the main device of the position registration signal based on the identification number, which is transmitted to the destination base station once or a plurality of times, and the destination base station which has received the burst signal notifies the main device of the mobile station. Is located in the radio zone of the base station.Whenever the mobile station updates the standby radio zone, the uplink control channel contains the mobile station terminal identification number. The base station, which has transmitted the strike signal once or a plurality of times, notifies the main unit of the position registration signal based on the identification number to determine which base station the mobile station is located in the wireless zone. It can be identified by the main device.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. FIG. 1 is a block diagram showing the system configuration of a system cordless telephone in an embodiment of the device of the present invention.

In FIG. 1, reference numeral 11 is a main unit having a position management function, 121 to 125 are base stations connected to the main unit 31, and 13 is a slave unit (mobile station) connected to the base stations 121 to 125 for communication. The slave unit 13 has a function of transmitting a burst signal including a terminal identification number to the base station once or a plurality of times each time it moves to a standby wireless zone of any one base station. Each of the base stations 121 to 125 that has received the
1 has the function of notifying.

Next, the position identifying operation of the system cordless telephone configured as described above will be described with reference to FIG.

In FIG. 1, when the handset 13 moves from the radio zone of the base station 121 to the radio zone of the base station 122, the handset 13 includes its own terminal identification number on the uplink control channel, as shown in FIG. The burst signal is transmitted to the base station 122 once or plural times. The base station 122 receives this burst signal and notifies the main unit 11 of the position registration signal indicating the slave unit. Thereby, the main device 11 identifies that the mobile device 13 has moved to the wireless zone of the base station 122.

In this state, when there is an incoming call to the handset 13, the base station 122 can notify the handset 13 of an incoming call by transmitting an incoming call signal only to the base station 122. .

As described above, according to this embodiment, the main device can recognize which base station the slave is located under, and can easily provide application services such as man location. . Further, the incoming signal only needs to be transmitted to one base station, and the burst signal for location registration transmitted by the handset does not use the wireless channel for communication, thus improving the wireless use efficiency. The system traffic can also be improved.

[0018]

As described above, according to the present invention, each time the mobile station updates the standby radio zone, a burst signal including the terminal identification number of the mobile station is sent by the uplink control channel once or a plurality of times.
