Abstract
The present invention is aimed to the provision of a mechanism whereby roaming users can specify whether they prefer to dial numbers belonging to the home network in local format or in international format from the visited network where they are roaming so that the treatment of restrictions based on the type of call, and depending on both user's geographical location and preferences, are correspondingly applied. Therefore, the present invention provides for a new method whereby information about a location of the user, taking into account the access location and user preferences, is sent from a home subscriber server to a serving call session control function entity, both in the home network for the user.
