Abstract

A method for providing feature support is provided that includes receiving, by a mobile station, multiple cell calls and coordinating media associated with the cell calls in order to make a feature of the mobile station functional for an end user of the mobile station. The feature is invoked after the mobile station has roamed from an enterprise network to a cellular network and experienced a handoff.

Claims

1. An apparatus for providing feature support, comprising:

a mobile station operable to receive multiple cell calls and to coordinate media in order to make a feature of the mobile station functional for an end user of the mobile station, wherein the feature is invoked after the mobile station has roamed from an enterprise network to a cellular network and experienced a handoff.

2. The apparatus of claim 1, wherein if any of the calls are terminated, the mobile station is made aware of the termination.

3. The apparatus of claim 1, wherein the feature is a selected one of a group of features, the group consisting of:

1) HOLD;

2) resume;

3) retrieve;

4) call-waiting;

5) conferencing;

6) transfer;

7) caller ID;

8) redirect;

9) three-way calling; and

10) barging operations.

4. The apparatus of claim 1, wherein the mobile station is operable to communicate with a mobility application to achieve the handoff, and wherein the mobile station is further operable to communicate a call ID to the mobility application to uniquely distinguish a second call from a first call, which was an original call for the mobile station.

5. The apparatus of claim 1, wherein the mobile station is operable to uniquely identify a first call and a second call by establishing a unique call ID during call set-up of the second call received by the mobile station.

6. The apparatus of claim 5, wherein the unique call ID leverages dual tone multi-frequency (DTMF) codes.

7. The apparatus of claim 5, wherein the unique call ID is executed in-band.

8. The apparatus of claim 1, wherein the mobile station is operable to hand off the calls when it roams from the cellular network and back into the enterprise network.

9. A method for providing feature support, comprising:

receiving, by a mobile station, multiple cell calls; and

coordinating media associated with the cell calls in order to make a feature of the mobile station functional for an end user of the mobile station, wherein the feature is invoked after the mobile station has roamed from an enterprise network to a cellular network and experienced a handoff.

10. The method of claim 9, wherein if any of the calls are terminated, the mobile station is made aware of the termination.

11. The method of claim 9, further comprising:

communicating with a mobility application to achieve the handoff; and

communicating a call ID to the mobility application to uniquely distinguish a second call from a first call, which was an original call for the mobile station.

12. The method of claim 9, further comprising:

uniquely identifying a first call and a second call by establishing a unique call ID during call set-up of the second call received by the mobile station.

13. The method of claim 12, wherein the unique call ID leverages dual tone multi-frequency (DTMF) codes.

14. The method of claim 12, wherein the unique call ID is executed in-band.

15. The method of claim 9, further comprising:

handing off the calls when the mobile station roams from the cellular network and back into the enterprise network.

16. Software for providing feature support, the software being embodied in a computer readable medium and comprising computer code such that when executed is operable to:

receive multiple cell calls; and

coordinate media associated with the cell calls in order to make a feature of a mobile station functional for an end user of the mobile station, wherein the feature is invoked after the mobile station has roamed from an enterprise network to a cellular network and experienced a handoff.

17. The medium of claim 16, wherein if any of the calls are terminated, the mobile station is made aware of the termination.

18. The medium of claim 16, wherein the code is further operable to:

communicate with a mobility application to achieve the handoff; and

communicate a call ID to the mobility application to uniquely distinguish a second call from a first call, which was an original call for the mobile station.

19. The medium of claim 16, wherein the code is further operable to:

uniquely identify a first call and a second call by establishing a unique call ID during call set-up of the second call received by the mobile station.

20. The medium of claim 16, wherein the code is further operable to:

hand off the calls when the mobile station roams from the cellular network and back into the enterprise network.

21. An apparatus for providing feature support, comprising:

a mobile station operable to receive multiple cell calls and to coordinate media in order to make a feature of the mobile station functional for an end user of the mobile station, wherein the feature is invoked when the mobile station is in a cellular network.

22. The apparatus of claim 21, wherein if any of the calls are terminated, the mobile station is made aware of the termination.

23. The apparatus of claim 21, wherein the feature is a selected one of a group of features, the group consisting of:

1) HOLD;

2) resume;

3) retrieve;

4) call-waiting;

5) conferencing;

6) transfer;

7) caller ID;

8) redirect;

9) three-way calling; and

10) barging operations.

24. The apparatus of claim 21, wherein the mobile station is operable to communicate with a mobility application, and wherein the mobile station is further operable to communicate a call ID to the mobility application to uniquely distinguish a second call from a first call, which was an original call for the mobile station.

25. The apparatus of claim 21, wherein the mobile station is operable to uniquely identify a first call and a second call by establishing a unique call ID during call set-up of the second call received by the mobile station.

26. The apparatus of claim 25, wherein the unique call ID leverages dual tone multi-frequency (DTMF) codes.

27. The apparatus of claim 25, wherein the unique call ID is executed in-band.
