System and method for controlling VCC functionality in a network environment including IMS
First Claim
1. A method of controlling voice call continuity (VCC) functionality of a user equipment (UE) device with respect to a call in a network environment including a visited network and an Internet Protocol (IP) multimedia subsystem (IMS) network, comprising:
- detecting a VCC operational mode associated with said UE device; and
generating a message by said UE device towards said network environment having a VCC application server node disposed in said IMS network, said message being generated pursuant to a call originated by said UE device while roaming in said visited network, wherein said message includes a VCC operational mode indicator indicative of said VCC operational mode that is selectable by a user of said UE device.

Abstract
In one embodiment, a scheme is disclosed for controlling voice call continuity (VCC) functionality of a user equipment (UE) device with respect to a call in a network environment including a visited network and an IP multimedia subsystem (IMS) network. The UE device'"'"'s VCC operational mode is provided to be selectably alterable responsive to user input. Upon detecting the VCC operational mode of the UE device, a message is generated by the UE device towards the network environment including a VCC application server node disposed in the IMS network, the message being generated pursuant to a call originated by the UE device while roaming in the visited network, wherein the message includes a VCC operational mode indicator indicative of the UE device'"'"'s VCC operational mode.

12. A wireless user equipment (UE) device operable to originate a call in a network environment including a visited network and an Internet Protocol (IP) multimedia subsystem (IMS) network, comprising:
-
means for selecting a VCC operational mode associated with said UE device; and
means for generating a message towards said network environment having a VCC application server node disposed in said IMS network, said message including a VCC operational mode indicator indicative of said VCC operational mode that is selectable by a user of said UE device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A voice call continuity (VCC) application server node operable in a network environment including a visited network and an Internet Protocol (IP) multimedia subsystem (IMS) network, comprising:
-
means for determining whether a call originated with respect to a user equipment (UE) device is to be anchored in said IMS network based on a message propagated responsive to said call from said UE device, said message including a VCC operational mode indicator indicative of a VCC operational mode associated with said UE device; and
means for generating a routing message to said visited network based on a determination that said VCC operational mode indicator is indicative of a de-selected status with respect to said UE device'"'"'s VCC operational mode. - View Dependent Claims (22, 23, 24, 25, 26, 27)
