BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile radio telephone receiving system, and more particularly to a mobile radio telephone receiving system having a plurality of exchanges in a network.

[0002]

2. Description of the Related Art An example of this type of mobile radio telephone receiving system is disclosed in Japanese Patent Laid-Open No. 5-218951.

This is a technology relating to a private network configured so that even when a mobile radio telephone moves from an exchange whose location is registered to another exchange, outgoing and incoming connections can be made.

According to this technique, when calling a mobile radio telephone from a telephone in the network, the incoming call is always connected to the exchange of the home station and transferred from the home station to the destination exchange to perform the incoming call connection.

[0005]

Therefore, there is a problem that connection delay and useless resources are used by the amount of passing through the home station of the mobile radio telephone.

It is therefore an object of the present invention to provide a mobile radio telephone receiving system capable of calling a mobile radio telephone that has moved without going through a home station.

[0007]

In order to solve the above problems, the present invention provides a mobile radio telephone receiving system having a plurality of exchanges in a network and a plurality of mobile radio telephones registered in the respective exchanges. If the mobile radio telephone moves from a switch that has registered its location to a different exchange, delete means for deleting the location registration of the mobile radio telephone from the source exchange and location registration of the mobile radio telephone to the destination exchange. Registration means, notification means for notifying that all the other exchanges from the destination exchange have registered their mobile radio telephones in their own exchanges, and the location registration information notified by the notifying means for each exchange. And a control means for controlling the incoming call based on the position registration information stored in the storage means.

[0008]

According to the present invention, the destination exchange informs all the other exchanges of the destination of the mobile radio, and the information is stored for each exchange. As a result, even if a mobile radio telephone that has moved through any of the exchanges is called, the exchange can recognize the movement destination, so that the mobile radio telephone that has moved directly via the destination exchange from the exchange can directly transfer to the mobile radio telephone. Incoming connection can be made.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram of an embodiment of a mobile radio telephone receiving system according to the present invention.

FIG. 2 is a diagram showing the contents of the location registration management memory before the location registration update. This figure shows that when a mobile radio telephone (hereinafter referred to as PS) 4 is registered in the MEM 12 of the PBX 1, the MEMs 12 of the PBXs 1 to 3,
22 and 32 show the contents.

In the PBX 1, the extension is "500".
This indicates that the PS4 having the number "0" and the ID number (identification number that each PS individually has) is "0110" is registered in the CS13. The station number is the area where the station number of the destination PBX is stored.
No. 4 is registered in its own PBX 1, so nothing is stored in this area.

On the other hand, in the MEMs 22 and 32 of the PBXs 2 and 3, the PS4 whose extension number is "5000" and whose ID number (the identification number that each PS individually has) is "0110" is the PBX1 whose station number is "10". Information that the location is registered in is written. Further, nothing is stored in the CS number areas of the PBXs 2 and 3. This is because PS4 is not registered in the PBXs 2 and 3.

PS4 of extension "5000" is now PBX
The case of moving from 1 to PBX 3 will be described. FIG.
FIG. 6 is a diagram showing the contents of a location registration management memory after location registration update.

When PS4 of extension "5000" moves from PBX1 to PBX3, PS4 is CS3 in PBX3.
