System and method for establishing communications between subscribers based on personal number assigned to each subscriber
First Claim
1. A personal communications method for establishing communications based on a personal identifier indicating a personal ID assigned to each subscriber, the method comprising the steps of:
- assigning to each subscriber said personal identifier and an additional identifier which is a sum of a group identifier indicating a group to which a subscriber belongs and a local identifier indicating a local ID of said subscriber within said group;
storing, in a personal data base, a location information of the subscriber associated with said personal identifier including an area identifier;
storing, in a group data base, a location information of the subscriber associated with the group identifier and the local identifier;
inputting into a group data base one of the personal identifier and the additional identifier which is a sum of the group identifier and the local identifier, of a destination subscriber;
retrieving location information of the destination subscriber using one of the personal identifier from the personal data base and the additional identifier which is a sum of the group identifier and the local identifier, from the group data base; and
establishing communications between a source subscriber and the destination subscriber based on the location information of the destination subscriber.

Abstract
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.

6. A personal communications method for personal communications system comprising a switching unit connected to a network, a personal data base connected to the switching unit, a group data base connected to the switching unit, and a terminal unit accommodated in the switching unit, the method comprising the steps of:
-
(a) assigning to each subscriber a personal identifier indicating a personal ID and an additional identifier which is a sum of a group identifier indicating a group to which a subscriber belongs and a local identifier indicating a local ID of said subscriber within said group; (b) storing a personal information associated with the personal identifier including an area identifier in the personal data base; (c) storing the personal information associated with the additional identifier in the group data base; (d) inputting one of the personal identifier and the additional identifier to the terminal unit by a source subscriber; (e) generating a packet addressed with the inputted personal identifier or the additional identifier; (f) broadcasting said packet over the network; (g) determining whether or not a destination address of said packet matches any group identifier stored in the group data base or any area identifier stored in the personal data base; (h) retrieving the personal information associated with one of the group identifier and the personal identifier which matches said destination address of said packet from one of the group data base and the personal data base, respectively; and (i) returning the personal information to said switching unit accommodating the source subscriber. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A personal communications system for establishing communications based on a personal identifier assigned to each subscriber and indicating a personal ID, the system comprising:
-
a personal data base for storing a personal information as associated with the personal identifier including an area identifier; a group data base for storing the personal information as associated with an additional identifier which is assigned to each subscriber and is a sum of a group identifier and a local identifier, said group identifier indicating a group to which a subscriber belongs, and said local identifier indicating a local ID of the subscriber within the group; a first switching unit, connected to a network, for accommodating a source subscriber; a second switching unit, connected to the network, for managing one of said group data base and said personal data base; a third switching unit, connected to the network, for accommodating a destination subscriber; and a terminal unit accommodated by one of said first, second and third switching unit, wherein; said first switching unit broadcasts over the network a packet addressed with one of the personal identifier and the additional identifier when the source subscriber has entered said one of the personal identifier and the additional identifier; it is determined whether or not a destination address of said packet matches any area identifier of the personal identifier stored in the personal data base or any group identifier stored in the group data base; the personal information, associated with one of the personal identifier and the additional identifier, which matches the destination address of said packet is retrieved from the personal data base or the group data base; and said second switching unit returns the retrieved personal information to said first switching unit. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A personal communications system for assigning a personal identifier indicating a personal ID to each subscriber, and for establishing communications between a source subscriber and a destination subscriber based on the personal identifier, the system comprising:
-
a personal data base for storing a personal information associated with the personal identifier including an area identifier; a group data base for storing the personal information associated with an additional identifier which is a sum of a group identifier and a local identifier, the group identifier indicating a group to which the subscriber belongs, and the local identifier indicates a local ID of the subscriber within the group; a first switching unit, connected to a layered network, for accommodating a source subscriber; a second switching unit, connected to the layered network, for managing one of said group data base and said personal data base; a third switching unit, connected to the layered network, for accommodating a destination subscriber; and a terminal unit accommodated by one of said first, second, and third switching unit, wherein; said first switching unit generates a packet addressed with one of the personal identifier and the additional identifier of the source subscriber when the source subscriber enters said one of the personal identifier and the additional identifier, and sends said packet to a switching unit in a higher order layer; said switching unit in the higher order layer copies said packet and sends a copied packet to switching units in a higher order layer, a lower order layer, and adjacent layers; said third switching unit which receives said packet determines whether or not a destination address of said packet matches any area identifier of the personal identifier stored in the personal database or any group identifier stored in the group data base; and said third switching unit retrieves the personal information associated with the personal identifier or the additional identifier which matches the destination address of said packet to said first switching unit. - View Dependent Claims (21)
