Abstract

In one embodiment, a method comprises a mobile node receiving an incoming wireless call; the mobile node determining whether enhanced services are available for the incoming wireless call based on outputting a DTMF tone on a voice channel associated with the incoming wireless call and determining whether a notify message, indicating a server providing the enhanced services has received the DTMF tone, is received on a data channel during the incoming wireless call; and the mobile node selectively initiating the enhanced services for the incoming wireless call with the server in response to determining the enhanced services are available for the incoming wireless call.

Claims

1. A method comprising:

a mobile node receiving an incoming wireless call;

the mobile node determining whether enhanced services are available for the incoming wireless call based on outputting a dual tone multiple frequency (DTMF) tone on a voice channel associated with the incoming wireless call and determining whether a notify message, indicating a server providing the enhanced services has received the DTMF tone, is received on a data channel during the incoming wireless call; and

the mobile node selectively initiating the enhanced services for the incoming wireless call with the server in response to determining the enhanced services are available for the incoming wireless call.

2. The method of claim 1, wherein the selectively initiating includes an enhanced services client circuit within the mobile node executing control over the incoming wireless call based on establishing data communications with the server via the data channel.

3. The method of claim 2, further comprising a user interface telephony circuit executing control over the incoming wireless call in response to a determined absence of the notify message.

4. The method of claim 3, wherein:

the enhanced services client circuit determines the determined absence of the notify message;

the user interface telephony circuit executing control based on the enhanced services client circuit releasing control of the incoming wireless call in response to determining the determined absence of the notify message.

5. The method of claim 3, wherein one of the enhanced services client circuit executes control over the incoming wireless call, or the user interface telephony circuit executing control over the incoming wireless call, based on whether the notify message is detected, prior to the mobile node generating a notification to notify a user of the mobile node of the incoming wireless call.

6. The method of claim 1, wherein the selectively initiating the enhanced services is executed prior to the mobile node generating a notification to notify a user of the mobile node of the incoming wireless call.

7. The method of claim 1, further comprising receiving enhanced services data from the server on the data channel and prior to the incoming wireless call, including storing the enhanced services data in a local memory, the selectively initiating including retrieving the enhanced services data from the local memory in response to a detected association between the incoming wireless call and the enhanced services data.

8. The method of claim 1, wherein the determining includes identifying whether the notify message specifies an acknowledgment digit matching a prescribed DTMF value of the DTMF tone.

9. An apparatus comprising:

a wireless network interface circuit configured for receiving an incoming wireless call; and

a second circuit configured for responding to the incoming wireless call by causing the wireless network interface circuit to output a dual tone multiple frequency (DTMF) tone on a voice channel associated with the incoming wireless call, the second circuit configured for determining whether enhanced services are available for the incoming wireless call based on determining whether a notify message, indicating a server providing the enhanced services has received the DTMF tone, is received on a data channel during the incoming wireless call, the second circuit further configured for selectively initiating the enhanced services for the incoming wireless call with the server in response to determining the enhanced services are available for the incoming wireless call.

10. The apparatus of claim 9, wherein the second circuit is configured for executing control over the incoming wireless call based on establishing data communications with the server via the data channel.

11. The apparatus of claim 10, further comprising a user interface telephony circuit configured for executing control over the incoming wireless call in response to a determined absence of the notify message by the second circuit.

12. The apparatus of claim 11, wherein the user interface telephony circuit is configured for executing control over the incoming wireless call based on the second circuit releasing control of the incoming wireless call in response to the second circuit determining the determined absence of the notify message.

13. The apparatus of claim 11, wherein one of the second circuit or the user interface telephony circuit executes control over the incoming wireless call, based on whether the notify message is detected, prior to the apparatus generating a notification to notify a user of the mobile node of the incoming wireless call.

14. The apparatus of claim 9, wherein the second circuit is configured for initiating the enhanced services prior to the apparatus generating a notification to notify a user of the mobile node of the incoming wireless call.

15. The apparatus of claim 9, further comprising a local memory configured for storing enhanced services data in response to the wireless network interface circuit receiving the enhanced services data from the server on the data channel prior to the incoming wireless call, the second circuit configured for retrieving the enhanced services data from the local memory in response to a detected association between the incoming wireless call and the enhanced services data.

16. The apparatus of claim 9, wherein the second circuit is configured for identifying whether the notify message specifies an acknowledgment digit matching a prescribed DTMF value of the DTMF tone.

17. An apparatus comprising:

a wireless network interface circuit configured for receiving an incoming wireless call; and

means Corresponding to the incoming wireless call by causing the wireless network interface circuit to output a dual tone multiple frequency (DTMF) tone on a voice channel associated with the incoming wireless call, the means for responding configured for determining whether enhanced services are available for the incoming wireless call based on determining whether a notify message, indicating a server providing the enhanced services has received the DTMF tone, is received on a data channel during the incoming wireless call, the means for responding further configured for selectively initiating the enhanced services for the incoming wireless call with the server in response to determining the enhanced services are available for the incoming wireless call.

18. Logic encoded in one or more tangible media for execution and when executed operable to:

receiving an incoming wireless call by a mobile node;

determining by the mobile node whether enhanced services are available for the incoming wireless call based on outputting a dual tone multiple frequency (DTMF) tone on a voice channel associated with the incoming wireless call and determining whether a notify message, indicating a server providing the enhanced services has received the DTMF tone, is received on a data channel during the incoming wireless call; and

selectively initiating, by the mobile node, the enhanced services for the incoming wireless call with the server in response to determining the enhanced services are available for the incoming wireless call.
