The system is arranged for implementing the method.

Abstract: An access point sends geographical positioning information from the access point to mobile terminals and to a mobile terminal which receives this information and estimates the position thereof based on said information. Geographical-locating architecture for WiFi 802.11 mobile terminals on ADSL access points generally includes geographical positioning information, i.e., the geographical coordinates of the access point during the registration phase thereof. The access point includes this geographical information in the information posted so that the mobile terminals can be connected to same. The mobile terminals can thus know the geographical location where they are located with an approximation that will depend directly on the number of access points that the mobile terminal can detect.

Abstract: The method comprises: i) obtaining, an authentication registrar (S-CSCF) of a IMS control layer, two sets of IMS credentials for a user: a first set from a user equipment (UE) and a second set from a Home Server Subscriber, or HSS (100); and ii) said authentication registrar (S-CSCF) comparing said first and second sets of IMS credentials, and depending on the result of said comparison granting or denying the access of said user to IMS services. The method further comprises, before and in order to perform said steps i) and ii), obtaining, the user equipment (UE), the first set of IMS credentials from a network element (40) via a HTTP-based mechanism. The system is adapted for implementing the method, and the network element is also adapted for implementing the method and for being included in the system.

Abstract: The invention relates to an access point (20) which sends geographical positioning information from the access point to mobile terminals (10) and to a mobile terminal which receives this information and estimates the position thereof based on said information. Geographical-locating architecture for WiFi 802.11 mobile terminals on ADSL access points generally consists of including geographical positioning information, i.e., the geographical coordinates of the access point during the registration phase thereof. The access point includes this geographical information in the information posted so that the mobile terminals can be connected to same. The mobile terminals can thus know the geographical location where they are located with an approximation that will depend directly on the number of access points that the mobile terminal can detect.
