Network support for mobile special alerting

1. A method comprising:

changing an alerting mode of a mobile terminal from an initial alerting mode to a first alerting mode and in response to changing the alerting mode to the first alerting mode communicating a first message via a telecommunications network where the first message comprises an indication of the change from the initial alerting mode to the first alerting mode;

changing the alerting mode from the first alerting mode to a second alerting mode in response to receiving at the mobile terminal a second message communicated via a telecommunications network, where the second message is received after expiration of a first timer interval, and the second message comprises a second timer interval;

the mobile terminal changes back to the first alerting mode after expiration of the second timer interval;

wherein the second alerting mode and the initial alerting mode comprises one of a silent mode, a vibrate mode, a ring mode, and a vibrate and ring mode; and

wherein the first alerting mode comprises one of a silent mode and a vibrate mode.

2. The method of claim 1 , wherein the first alerting mode is a silent mode and the second alerting mode is one of a ring mode, vibrate mode, and ring and vibrate mode.

3. The method of claim 1 , wherein the first alerting mode is a vibrate mode and the second alerting mode is one of a ring mode, and ring and vibrate mode.

4. The method of claim 1 , wherein the mobile terminal is configured to receive a third message that is communicated to the mobile terminal in response to a special alerting code, where the third message is sent while the mobile terminal is in the first alerting mode and in response receiving the third message the mobile terminal changes to the second alerting mode.

5. The method of claim 4 , wherein the special alerting code is entered by a calling terminal.

6. The method of claim 4 , wherein the first timer interval and the second timer interval are stored on the mobile terminal and the mobile terminal changes to the first alerting mode after expiration of the first timer interval and remains in the first alerting mode for a duration of the second timer interval.

7. The method of claim 6 , wherein the mobile terminal reverts to the first alerting mode after expiration of the second timer interval.

8. An apparatus comprising:

a mobile terminal wherein after changing from an initial alerting mode to a first alerting mode, the mobile terminal receives via a telecommunications network a first message after expiration of a first timer interval where the first message comprises a second timer interval;

wherein in response to receiving the first message, the mobile terminal changes from the first alerting mode to a second alerting mode for a duration of the second timer interval;

wherein at expiration of the second timer interval, the mobile terminal reverts to the first alerting mode.

9. The apparatus of claim 8 wherein the first alerting mode is the silent alerting mode and the second alerting mode is one of a ring mode, vibrate mode, and ring and vibrate mode.

10. The apparatus of claim 8 wherein the first alerting mode is a vibrate mode and the second alerting mode is one of a ring mode, and ring and vibrate mode.

11. The apparatus of claim 8 wherein:

the mobile terminal is configured to receive a second message that is communicated to the mobile terminal in response to a special alerting code, where the second message is sent while the mobile terminal is in the first alerting mode and in response receiving the second message the mobile terminal changes to the second alerting mode.

12. The apparatus of claim 11 wherein the special alerting code is communicated by a calling terminal.

13. The apparatus of claim 8 , wherein the first timer interval and the second timer interval are stored on the mobile terminal and the mobile terminal changes to the first alerting mode after expiration of the first timer interval and remains in the first alerting mode for a duration of the second timer interval.

14. The apparatus of claim 13 , wherein the mobile terminal reverts to the first alerting mode after expiration of the second timer interval.

15. A call controller that receives a first message indicating a change from an initial alerting mode to a first alerting mode;

wherein, after expiration of a first timer interval, the call controller communicates a second message comprising a second timer interval, where the second message indicates a change from the first alerting mode to a second alerting mode; and

the second timer interval indicates a timer interval after which a reversion from the second alerting mode to the first alerting mode occurs.

16. The call controller of claim 15 wherein the first alerting mode is a silent mode and the second alerting mode is one of a ring mode, vibrate mode, and ring and vibrate mode.

17. The call controller of claim 15 wherein the first alerting mode, is a vibrate mode and the second alerting mode is one of a ring mode, and ring and vibrate mode.

18. The call controller of claim 15 , wherein the call controller receives a third message, sent in response to a special alerting code, where the third message is received before expiration of the first tinier interval, and in response to receiving the third message the call controller communicates a fourth message indicating a change from the first alerting mode to the second alerting mode.

19. The call controller of claim 18 , wherein the special alerting code is sent by a calling terminal that is communicatively coupled with a communication network, where the special alerting code is provided to the calling terminal while the calling terminal is receiving one of a ringback tone and a voice-mail prompt.

20. The call controller of claim 19 wherein the special alerting code is provided to the calling party by the called party.
