Abstract

For users with user terminals in a wireless or mobile network, a mechanism is provided for returning a representative location based on the user'"'"'s profile settings and the user'"'"'s current physical location. The representative location is not the user'"'"'s actual physical location, but a conceptual location used for reporting the user'"'"'s physical location in order to activate various functions and capabilities of the user terminal according to where the user is located. By employing representative locations, various necessary information and corresponding relationships between the user'"'"'s actual location, which may continuously change due to the user'"'"'s mobility, and the user preferences containing profile settings allowing the user'"'"'s terminal to operate in a certain manner designated for certain physical locations, are more efficiently handled and managed.
