Patent ID: 8638782

Claim:
A method for providing an incoming call directed to a terminal in a voice call continuity (VCC) service, the method comprising: receiving, by a VCC application server, first domain selection information from the terminal for storage in the VCC application server and storing, in the VCC application server, the received first domain selection information, wherein the first domain selection information is transmitted from the terminal to the VCC application server; performing, by the VCC application server, a domain selection for the incoming call based on either the first domain selection information or second domain selection information depending on which domain selection information has a relatively higher priority, wherein the first domain selection information is user preferences, the user preferences including domain selection information specifying a user-preferred domain to be used when transmitting the incoming call to the terminal, and wherein the second domain selection information is operator policy, the operator policy including domain selection information specifying a network-preferred domain to be used when transmitting the incoming call to the terminal; and transmitting, by the VCC application server, the incoming call over the selected domain selection, wherein if the first domain selection information has a higher priority than the second domain selection information, the performing step includes: selecting, by the VCC application server, either a circuit-switched (CS) domain or an IP multimedia subsystem (IMS) domain for the incoming call based on the first domain selection information, and wherein if the second domain selection information has a higher priority than the first domain selection information, the performing step includes: selecting, by the VCC application server, either the circuit-switched (CS) domain or the IP multimedia subsystem (IMS) domain for the incoming call based on the second domain selection information.
