Abstract

The position of a mobile station is properly monitored and is stored in a home location register. A call which indicates this mobile station as a calling/receiving station is set via any mobile service switching center. When monitoring a communication oriented by this call is necessary, the subscriber number of this mobile station is input by a test work station. Based on this subscriber number, an operation and maintenance center reads position data of the mobile station from the home location register and reports the data to the test work station. Based on the position data, the test work station specifies the mobile service switching center through which the call has been set, and transfer data specifying this mobile service switching center to the operation and maintenance center. The operation and maintenance center extracts the call-oriented voices from this mobile service switching center.

Claims

1. A mobile communications monitor system comprising:

a plurality of exchanges for communicating with an arbitrary mobile station and for relaying the communication with said mobile station;

a monitor device, connected to said plurality of exchanges, for extracting contents of communications relayed by said connected exchanges;

mobile-station specifying data input device for inputting specifying data of a mobile station to be monitored, into said monitor device; and

position data storage device, connected to said monitor device, for storing position data specifying locations of said mobile station, wherein;

when receiving said position data through said mobile-station specifying data input device, said monitor device reads position data of a mobile station, corresponding to said input specifying data, from said position data storage device and transmits said position data to said mobile-station specifying data input device,

upon reception of said position data, said mobile-station specifying data input device automatically specifies an exchange whose service area covers a position indicated by said read position data, and reports said specified exchange to said monitor device, and

when informed of said specified exchange, said monitor device orders said specified exchange to extract a content of the communication with the mobile station corresponding to said mobile-station specifying data from said specified exchange.

2. The mobile communications monitor system according to claim 1, wherein said mobile-station specifying data input device has a table in which a position indicated by said position data is associated with said exchange whose service area covers said position.

3. The mobile communications monitor system according to claim 1, wherein said position data storage device registers positions of individual mobile stations informed through communications with said mobile stations.

4. The mobile communications monitor system according to claim 3, wherein said plurality of exchanges are mutually connected by a higher-rank exchange.

5. The mobile communications monitor system according to claim 3, wherein said plurality of exchanges are connected to said monitor device.

6. A mobile communications monitor system comprising:

a plurality of exchanges for communicating with an arbitrary mobile station and for relaying the communication with said mobile station;

a monitor device connected to said plurality of exchanges for outputting contents of communications relayed by said connected exchanges;

mobile-station specifying data input device for inputting specifying data of a mobile station to be monitored, into said monitor device; and

position data storage device, connected to said exchanges, for storing position data specifying locations of said mobile station, wherein;

when receiving said position data through said mobile-station specifying data input device, said monitor device transmits said input specifying data to any exchange, and

an exchange which receives said mobile-station specifying data reads position data of a mobile station, corresponding to said received specifying data, from said position data storage device, automatically specifies an exchange whose service area covers a position indicated by said read position data, orders said specified exchange to extract a content of a communication from a mobile station corresponding to said specific data from said specified exchange, and relays the extracted content of the communication to the monitor device.

7. The mobile communications monitor system according to claim 6, wherein each of said exchanges has a table in which a position indicated by said position data is associated with said exchange whose service area covers said position.

8. The mobile communications monitor system according to claim 6, wherein said position data storage device registers positions of individual mobile stations informed through communications with said mobile stations.

9. The mobile communications monitor system according to claim 8, wherein said plurality of exchanges are mutually connected by a higher-rank exchange.

10. The mobile communications monitor system according to claim 8, wherein said plurality of exchanges are connected to said monitor device.
