Method for placing call in voice call continuity and terminal and server thereof
First Claim
1. A method for providing an incoming call directed to a terminal in a voice call continuity (VCC) service, the method comprising:
- storing, in a VCC application server, operator policy information and user preference information, the user preference information including domain selection information specifying a user-preferred domain to be used when transmitting the incoming call to the terminal, the operator policy information including domain selection information specifying a network-preferred domain to be used when transmitting the incoming call to the terminal; and
performing, by the VCC application server, a domain selection for the incoming call based on the user preference information or the operator policy information, depending on precedence information.

Abstract
A method, server and terminal for providing a Voice Call Continuity (VCC) service, are discussed. According to an embodiment, the terminal includes a storage unit to store operator policy information and user preference information, the user preference information including domain selection information specifying a user-preferred domain to be used when originating the outgoing call from the terminal, the operator policy information including domain selection information specifying a network-preferred domain to be used when originating the outgoing call from the terminal; and a controller to perform a domain selection for the outgoing call based on the user preference information or the operator policy information, depending on precedence information.
