Apparatus, and associated method, for facilitating radio control system operation with an ICS-capable wireless device
View Patent ↗An apparatus, and an associated method, for facilitating communication operations with a wireless device that is ICS or DTM capable. A message generator is provided, configured to generate a network-terminated message, the network-terminated message including a media feature tag that identifies support of ICS. When transmitted to a network node, the message is detected. And, a wireless-device-terminated message that provides for mapping of a SIP URI into a calling name presentation.
1. An apparatus for a wireless device, said apparatus comprising:
a message generator configured to generate a network-terminated message, the network-terminated message including a media feature tag that identifies wireless device support of ICS, IMS Centralized Service, and identifies network support of the necessary functionality to support ICS, the network support indicated in network-sent information sent to the wireless device.
2. The Apparatus of claim 1 wherein the network-terminated message generated by said message generator comprises a Session Initiation Protocol, SIP, message.
3. The apparatus of claim 1 wherein the media feature tag is embodied at an accept contact header part of the network-terminated message.
4. The apparatus of claim 1 wherein the media feature tag that identifies support of ICS identifies the wireless device to be DTM, Dual Transfer Mode, capable.
5. The apparatus of claim 1 wherein the media feature tag comprises a SIP feature tag.
6. The apparatus of claim 1 wherein said message generator is configured to generate the network-terminated message pursuant to a wireless-device registration.
7. The apparatus of claim 1 further comprising an initiator configured to cause initiation of generation of the network-terminated message by said message generator.
8. A method for generation of a network-terminated message, said method comprising:
initiating generation of a network-terminated message, the network-terminated message including a media feature tag that identifies network support of ICS, IMS Centralized Service, and identifies the wireless device to be DTM, Dual Transfer Mode, capable, the network support indicated in network-sent information; and
generating the network-terminated message.
9. The method of claim 8 wherein said initiating comprises initiating generation of a SIP, Session Initiation Protocol, message that includes the media feature tag.
10. The method of claim 8 wherein the media feature tag is embodied at an accept contact data header part of the network-terminated message.
11. The method of claim 8 further comprising:
sending the network-terminated message to a network, detecting delivery of the network-terminated message at the network, and performing terminating access domain selection responsive to values of the media feature tag of the network-terminated message.
12. The method of claim 11 further comprising sending, responsive to the network-terminated message, a SIP, Session Initiation Protocol, message to a circuit-switched network entity.
13. The method of claim 12 wherein the SIP message comprises a SIP INVITE message.
14. An apparatus for a wireless network, said apparatus comprising:
a detector configured to detect delivery at the wireless network of a wireless device generated message, the wireless device generated message including a media feature tag that identifies wireless device support of ICS, and the wireless device to be DTM, dual transfer mode, capable, the wireless device message formed responsive to network-sent information indicating network support of ICS.
15. A method for facilitating an ICS (IMS Centralized Service), said method comprising:
detecting a message at a network node, the message intended for wireless-device termination; and
generating a wireless-device-terminated message that provides for mapping of a SIP URI into a calling name presentation, the wireless-device-terminated message indicating network support of ICS.
16. An apparatus for facilitating an ICS (IMS Centralized Service), said apparatus comprising:
a detector configured to detect a message at a network node, the message intended for wireless-device termination; and
a message generator configured to generate a wireless-device-terminated message that provides for mapping of a SIP URI into a calling name presentation, the wireless-device-terminated message indicating network support of ICS.
