The aim of the invention is to localise a terminal () when accessing an IP service (), by means of an access network (). To this end, a method for allocating an IP address to the terminal () is carried out, a database () memorises the IP address allocated to the terminal () in association with a terminal or user identifier and an identifier of an access point wherein the terminal accesses the access network (), the access point being associated with localisation information, and the database transmits the localisation information associated with the identifier of the terminal or the user to the service.

Method and system for localising users for services based on SIP or H.323  protocols with dynamic IP address allocation

The method consists in: a user terminal issuing an access request to an access or IP service provider, the request containing user identification and authentication data with the provider and with an access and IP transport network operator, the access request being transmitted via the access network to an authentication server of the access or IP service provider; previously transmitting the access request to an authentication server of the network operator; the authentication server performing a procedure to authenticate the user on the basis of user identification data with the provider; and transmitting a response message to the user terminal, which response message contains the results of the user authentication by the authentication servers.
