ABSTRACT:
The present invention discloses a system and a method for performing routing using location information of an IP terminal in a mobile IP telephony network. When a call is originated from an IP terminal to another subscriber it is checked whether location information of the IP terminal is required for the call. In case location information is required, the location information is added to the call setup data. Then, a destination address is determined on the basis of the call setup data and the location information. Finally, the call is routed to the determined destination address.
