Abstract

In a packet switching data transmission network on the one hand, and in a public telephone network on the other hand, a station (14) is started, the networks being interconnected via a call server (15). The transmission network comprises an administration server (11), a plurality of subnets administered by the administration server and a plurality of stations (14), each linked to a subnet. The administration server stores a respective location information for each subnet. A station emits a lease request (301), destined for the administration server. Then, the station receives from the administration server, in response to the lease request, a lease (302) containing the location information of the subnet of the station. Next, the station emits, destined for the call server, a registration request (304) comprising an identifier of the station as well as the location information. Then, on receipt of this request, the call server stores (305) in a call database a information associating the identifier of the station and the location information.
