Abstract

See full text

The present invention aims at realizing a real-time call process by performing a timesaving operation in retrieving personal information in a personal communications system for establishing communications based on a unique personal number assigned to each subscriber. In addition to a unique personal number, each subscriber can be assigned a group number identifying a group to which the subscriber belongs and a local number of the group. For example, if a source subscriber specifies as a destination number the group number+local number of subscriber B, a service control point 11 broadcasts over a network a packet addressed with the group number+local number of subscriber B. Each of the service control points in the network determines whether or not a data base connected to it stores a group number which matches the destination address of the packet. If yes, the packet is received. Then, the associated data base retrieves the personal information associated with the destination address of the received packet, that is, the personal information on subscriber B, and returns to the service control point 11 the packet provided with the personal information on subscriber B. The service control point 11 performs a routing process according to the location information.
