Abstract

A message redirection system includes a data protocol detector for detecting an alert message of a particular protocol received by the mobile station, a user interface manager for displaying user-interactive prompts in response to the detected alert message and accepting user input for redirecting the data message to a communications network element, and an encoder for encoding the user input into a modulating signal compatible with a communications channel.

Claims

1. A message redirection system for a mobile station, the system comprising:

a data protocol detector for detecting an alert message of a data protocol received by the mobile station;

a user interface manager for providing user-interactive prompts in response to the detected alert message and accepting user input for redirecting a data message that corresponds to the alert message; and

an encoder for encoding the user input into a modulating signal used as an alert response message corresponding to the redirected data message, said encoder including a control channel that transmits the alert response message to communications network elements, including to communications network elements other than the communication network element from which the original alert message was received.

2. The system according to claim 1 further comprising:

a storage medium for storing the accepted user input to facilitate repetitious transmission of the user input from the mobile station to a base station.

3. The system according to claim 2 wherein the storage medium comprises at least a segment of a phone-number memory arranged to communicate with the user interface manager so as to dynamically and automatically store accepted user input.

4. The system according to claim 1 further comprising:

an audio circuit for accepting audio input at a transducer;

a muting device for muting the audio input at the transducer during a time interval when the user input is transmitted, the muting device coupled to the audio circuit and the user interface manager.

5. The system according to claim 1 further comprising:

an audio circuit having a speaker for providing audio output;

a muting device for muting any sidetone audio associated with the audio output and resulting from a feedback transmission path between the user input and the speaker, the muting device coupled to the audio circuit and the user interface manager.

6. The system according to claim 1 wherein the data protocol detector comprises a detector for detecting short message service data as the alert message of the particular data protocol.

7. The system according to claim 1 wherein the modulating signal is selected from a group of voice-channel compatible signals consisting of a single tone signal, dual tone signal, a dual-tone multiple frequency signal, a sub-audible frequency signal, and an audible frequency signal.

8. The system according to claim 1 wherein the user-interactive prompt comprises a voice message generated by a wireless data server.

9. The system according to claim 1 wherein the user interactive prompt comprises a set of alphanumeric characters that is displayable one a display of the mobile station.

10. The system according to claim 1, wherein the control channel enables the alert response message to be immediately transmitted without initiating a voice-channel setup sequence in advance.

29. The system according to claim 1, wherein said encoder is configured so that upon receipt of the alert message the control channel enables automatic or dynamic availability of a voice channel for subsequent transmission of the alert response message.

11. A message redirection system for a mobile station, the system comprising:

a data protocol detector for detecting an alert message of a first data protocol received by the mobile station;

a user interface manager for providing user-interactive prompts in response to the detected alert message and accepting user input for redirecting a data message that corresponds to the alert message; and

an encoder for encoding the user input into a alert response message having a second data protocol distinct from the first data protocol, said encoder including a control channel that transmits the alert response message to communications network elements, including to communications network elements other than the communication network element from which the original alert message of the first data protocol was received.

12. The system according to claim 11 wherein the first data protocol is consistent with data signaling of a short messaging service and wherein the second data protocol is consistent with data signaling of an access channel of a time-division multiple access system.

13. The system according to claim 11 wherein the first data protocol is consistent with data signaling of a short messaging service and wherein the second data protocol is consistent with data signaling of an access channel of a code-division multiple-access system.

14. The system according to claim 11 wherein the encoder is adapted to transmit the alert message response over an access channel as the control channel, the alert message including a message preamble having a preamble size and a message capsule having a capsule size maximized by a commensurate reduction in the preamble size consistent with reliable synchronization and maintenance of a constant duration for a time slot of the access channel.

15. The system according to claim 11 wherein the control channel comprises an access channel and wherein the alert response message includes a message-type field with an indicator for distinguishing the alert message response from any access message and any response message transmitted over the access channel.

16. The system according to claim 11 wherein the control channel comprises an access channel and wherein the encoder is adapted to transmit an alert message response having a preamble with a preamble size and a message capsule with a capsule size, the preamble size being dynamically determined based upon a signal parameter measurement for a mobile station within a geographic coverage area.

17. The system according to claim 11 wherein the user-interactive prompt comprises a voice message generated by a wireless data server.

18. The system according to claim 11 wherein the user interactive prompt comprises a set of alphanumeric characters that is displayable on a display of the mobile station.

19. The system according to claim 11, wherein the control channel enables the alert response message to be immediately transmitted without initiating a voice-channel setup sequence in advance.

30. The system according to claim 11, wherein said encoder is configured so that upon receipt of the alert message the control channel enables automatic or dynamic availability of a voice channel for subsequent transmission of the alert response message.

20. A method for redirecting a data message for a mobile station, the method comprising:

detecting an alert message of a particular data protocol received by the mobile station;

providing user-interactive prompts derivable predominately at the mobile station in response to the detected alert message and accepting user input for redirecting a data message, corresponding to the alert message, to a communications network element; and

21. The method according to claim 20 wherein the detecting step comprises detecting short message service data as the alert message of the particular data protocol.

22.
