Abstract
A method for handling CS (Circuit Switching) calls in a VCC (Voice Call Continuity), a VCC application server and an apparatus thereof, wherein first, the VCC application identifies whether a called party number of CS domain calls routed thereto is in an international format, secondly, the VCC application may request to convert the format of the called party number into the international format (referred to as 'routable number') if the called party number is not in the international format, thirdly, a translation entity may convert the called party number into the routable number by adding an international prefix suitable for a current location of the originating terminal based on both the called party number and location information on the originating terminal, and then the calls may continue in an IMS domain or a CS domain by the routable number.
