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:
- performing, by a VCC application server, a domain selection for the incoming call based on either 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, andwherein the second domain selection information is operator policy, the operator policy including domain selection information specifying an operator-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,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, orwherein 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.

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.

9. A method for providing an outgoing call originating from a terminal subscribed to a voice call continuity (VCC) service, the method comprising:
-
performing, by the terminal, a domain selection for the outgoing call originating from the terminal based on first domain selection information or second domain selection information, wherein the first domain selection information is user preferences and the second domain selection information is operator policy; and transmitting, by the terminal, the outgoing call over the selected domain, wherein the performing step includes;
selecting, by the terminal, either a circuit-switched (CS) domain or an IP multimedia subsystem (IMS) domain for the outgoing call based on either the first domain selection information or the second domain selection information depending on which domain selection information has a relatively higher priority,wherein if the first domain selection information has a higher priority than the second domain selection information, the performing step includes;
selecting, by the terminal, either the circuit-switched (CS) domain or the IP multimedia subsystem (IMS) domain for the outgoing call based on the first domain selection information, orwherein if the second domain selection information has a higher priority than the first domain selection information, the performing step includes;
selecting, by the terminal, either the circuit-switched (CS) domain or the IP multimedia subsystem (IMS) domain for the outgoing call based on the second domain selection information. - View Dependent Claims (10, 11, 12, 13)

14. A device for providing service continuity and selecting a domain for an incoming call directed to a terminal in the service, the device comprising:
-
a storage unit to store therein 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 operator-preferred domain to be used when transmitting the incoming call to the terminal; a domain selection function unit to perform a domain selection for the incoming call based on the user preference information or the operator policy information; and a Device Management (DM) unit to transmit the user preference information including the set domain selection information from the device to the terminal for storage in the terminal, wherein the domain selection function unit selects either a circuit-switched (CS) domain or an IP multimedia subsystem (IMS) domain for the incoming call based on the domain selection information of the user preference information, if the user preference information has a higher priority than the operator policy information, or wherein the domain selection function unit selects either the circuit-switched (CS) domain or the IP multimedia subsystem (IMS) domain for the incoming call based on the domain selection information of the operator policy information, if the operator policy information has a higher priority than the user preference information. - View Dependent Claims (15, 16)

17. A terminal for providing service continuity and selecting a domain for an outgoing call originating from the terminal in the service, the terminal comprising:
-
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 operator-preferred domain to be used when originating the outgoing call from the terminal; a controller to perform a domain selection for the outgoing call based on either the user preference information or the operator policy information; and a Device Management (DM) unit to receive the operator policy information for storage in the storage unit, wherein the terminal supports voice call continuity (VCC) that is a home Internet Protocol multimedia subsystem (IMS) application capable of transporting voice calls between a circuit-switched (CS) domain and an IP multimedia subsystem (IMS) domain, wherein the controller selects either the circuit switched (CS) domain or the IP multimedia subsystem (IMS) domain for the outgoing call based on the domain selection information of the operator policy information or the user preference information, and wherein the controller selects either the circuit switched (CS) domain or the IP multimedia subsystem (IMS) domain for the outgoing call based on the domain selection information of the user preference information, if the user preference information has a higher priority than the operator policy information, or wherein the controller selects either the circuit switched (CS) domain or the IP multimedia subsystem (IMS) domain for the outgoing call based on the domain selection information of the operator policy information, if the operator policy information has a higher priority than the user preference information. - View Dependent Claims (18, 19)
