Abstract

A client for a text-based messaging application for a dual-mode mobile communication device may initiate an audio conference based on a text-based message. Contents of fields of the text-based message may be extracted and utilized to construct an audio conference request message that is subsequently transmitted to an audio conference gateway. Where the text-based messaging application is an instant messaging (IM) client application, it may be configured to recognize a voice connection as being related to an ongoing Data Mode IM conversation. As a consequence of the recognition, the IM client application may maintain the user interface for facilitating participation in the Voice Mode IM conversation. Updates related to the status of the Voice Mode IM conversation may be received at the dual-mode mobile communication device over the voice connection and reflected in changes to the user interface.

Claims

1. A method of initiating an audio conference at a mobile communications device, said method comprising:

receiving a text-based message over a data network;

extracting contents of at least two fields of said text-based message;

utilizing said contents in constructing an audio conference request message;

transmitting said audio conference request message over said data network to an audio conference gateway, said audio conference gateway being capable of establishing voice channels between said audio conference gateway and devices associated with telephone destination numbers and of bridging said voice channels;

establishing a voice connection with said audio conference gateway subsequent to said transmitting; and

receiving status information from said audio conference gateway in-band over said voice connection;

wherein said extracting contents of at least two fields of said text-based message includes;

determining an identity of an originator associated with said text-based message;

determining an identity of a primary receiver associated with said text-based message; and

determining an identity of a secondary receiver associated with said text-based message;

and wherein said utilizing said contents to construct said audio conference request message includes;

determining, based on said identity of said originator, a telephone destination number (DN) for an originator device, where said audio conference gateway is capable of establishing a voice channel with said originator device;

determining, based on said identity of said primary receiver, a telephone DN for a primary receiver device, where said audio conference gateway is capable of establishing a voice channel with primary receiver device; and

determining, based on said identity of said secondary receiver, a telephone DN for a secondary receiver device, where said audio conference gateway is capable of establishing a voice channel with said secondary receiver device; and

configuring said audio conference request message to initiate an audio conference, said audio conference request message including said telephone DN for said originator device and said telephone DN for said primary receiver device and said telephone DN for said secondary receiver device.

2. The method of claim 1 wherein said text-based message is an e-mail message.

3. The method of claim 1 wherein said extracting contents of at least two fields comprises extracting contents of a “

FROM”

field of said text-based message.

4. The method of claim 2 wherein said extracting contents of at least two fields comprises extracting contents of a “

TO”

field of said text-based message.

5. The method of claim 2 wherein said extracting contents of at least two fields comprises extracting contents of a “

CC”

field of said text-based message.

6. The method of claim 1 wherein said utilizing said contents in constructing said audio conference request message further comprises:

determining, from said contents, an instant messaging group to associate with said instant messaging message;

determining an identity for a first member of said instant messaging group; and

determining an identity for a second member of said instant messaging group.

7. The method of claim 2 wherein said determining, based on said identity of said primary receiver, a telephone DN for a primary receiver device, comprises using said identifier of said primary receiver as a key into a database of contact information.

8. The method of claim 1 wherein said voice channels are established over a public switched telephone network (PSTN).

9. The method of claim 1 wherein said voice connection is a public switched telephone network connection.

10. The method of claim 9 wherein where said receiving said status information comprises receiving Dual Tone Multiple Frequency signaling.
