Method and apparatus for message callback in a communication system
View Patent ↗The present invention encompasses various embodiments that provide convenient message callback for users in multi-service communication systems (e.g., 100 ). One set of embodiments enables users leaving messages to provide the callback number or address. This allows the calling party to indicate what communication service is preferable for callback. Another set of embodiments enables users retrieving messages to select the communication service they prefer for callback. The message server ( 114 ) provides this functionality by determining the callback number or address of the preferred type from the callback information provided by the original calling party. The present invention also provides for automatic callback once the called communication unit ( 102 ) receives the callback number or address.
1. A method for a communication unit to perform message callback, the method comprising:
receiving, from a message server via a short message service, callback information associated with messaging information for the communication unit; and
initiating callback automatically, without user intervention, using the callback information received.
2. The method of claim 1 further comprising requesting the callback information from the message server.
3. The method of claim 2 further comprising receiving, from the message server, an indication that callback information of at least one type is available.
4. The method of claim 3 wherein the at least one type is at least one type selected from the group consisting of a dispatch identifier, a group dispatch identifier, a private dispatch identifier, a telephone number, a pager number, a fax number, a number spoken in the messaging information, a number provided by a calling party, an email address, and an internet protocol address.
5. The method of claim 3 wherein requesting the callback information comprises indicating which one of the at least one type is requested.
6. The method of claim 5 wherein indicating which one of the at least one type is requested comprises transmitting a DTMF signal.
7. The method of claim 1 , wherein the message server comprises a server selected from the group consisting of a voice mail server, an email sewer, and a fax server.
8. A method for a communication unit to perform message callback, the method comprising:
receiving, from a message server, an indication that callback information is available, wherein the callback information is associated with messaging information for the communication unit on the message server;
indicating, to the message server a type of callback information requested;
receiving, from the message server via a short message service, the callback information requested; and
initiating callback automatically, without user intervention, using the callback information received.
9. A communication unit comprising:
a receiver adapted to receive, from a message server via a short message service, callback information associated with messaging information for the communication unit;
a transmitter; and
a processor, coupled to the receiver and the transmitter, adapted to instruct the transmitter to transmit signaling to automatically, without user intervention, initiate callback using the callback information received.
10. A communication unit comprising:
a receiver adapted to receive, from a message sewer, an indication that callback information is available and adapted to receive, from the message server via a short message service, requested callback information, wherein the callback information is associated with messaging intonation for the communication unit on the message sever;
a transmitter; and
a processor, coupled to the receiver and the transmitter, adapted to instruct the transmitter to transmit signaling to indicate, to the message server, a type of callback information requested and adapted to instruct the transmitter to transmit signaling to automatically, without user intervention, initiate callback using the callback information received.
