Define the digits that indicate the person number,
The private packet switching network number performs routing and call control between the destination subscriber accommodating switching center of the packet switching network and the corresponding private packet switching center, and the private packet switching center recognizes the private packet switching network subscriber number. The call is set up to the appropriate destination subscriber.

The subscriber number is given, * indicates the private packet switching network connection, XX indicates the private packet switching network number accommodated in the switching center N2, and △△ indicates the subscriber number within the private packet switching network. It is. Let us assume communication between a general subscriber T1 in a packet-switched network and a subscriber S1 in a private packet-switched network. General subscriber T
1 sends the destination subscriber number 31*××△△ to the packet switch N1. The packet switch N1 routes to the destination subscriber station N2. Incoming exchange N
2 detects * from destination subscriber number 31 *××△△, recognizes it as a call to a private packet switching network, and continues ×
Based on the private packet switching network number of x, the corresponding private packet switching network is detected and a call is made. At this time, the subscriber number △△ within the private packet switching network is transmitted to the private packet switching network without any control.

がある。 As explained above, the present invention defines digits indicating a private packet-switched network number and a subscriber number within the private packet-switched network in the subscriber number system used for general subscribers of a packet-switched network. This simplifies the connection with the private packet-switched network subscriber by not recognizing the private packet-switched network subscriber number and performs routing and call control according to the private packet-switched network number. This also has the effect of maintaining flexibility in the network number system.
