Abstract

A system and methods for transmitting and receiving text messages, in a messaging dialog with a recipient device, while maintaining the context of the messages without explicit mention of the context in the message is disclosed herein. In an embodiment of the invention, the system utilises a plurality of channels to determine the context of a received text message, based on a record of the channel and the context of a previous message.

Claims

1. A method of transmitting a text message, from a dialog engine to a recipient device, in a messaging dialog, over one of a plurality of unique channels, to preserve the context of the messaging dialog, the method comprising:

generating the text message;

selecting one of the plurality of channels for transmitting the generated text message to the receiving device over the selected channel; and

associating the selected channel and the context of the text message.

2. The method of claim 1, wherein the plurality of channels are logical.

3. The method of claim 1, wherein the selected channel and the context of the text message are associated with each other in a database.

4. The method of claim 1, wherein the text message has no subject field.

5. The method of claim 1, wherein the plurality of channels are each defined by unique originating and destination addresses.

6. The method of claim 1, wherein the step of selecting includes examining the associated channel information to find a channel not previously used.

7. A method of determining the context of a text message in a messaging dialog, the text message received from a transmitting device, through one of a plurality of unique channels by a dialog engine having a record of associated unique channel and context pairings, the method comprising:

receiving the transmitted text message;

identifying the channel through which the received text message was transmitted; and

determining the context of the received text message based on the record of associated unique receiving channel and context pairing.

8. The method of claim 7, further including the step of removing, from the record, the channel and context pairing corresponding to the received message following the step of determining the context of the received text message.

9. The method of claim 7, wherein the channels are logical.

10. The method of claim 7, wherein the channel is identified by the originating and destination addresses.

11. The method of claim 7, wherein the step of determining the context includes referencing a database using the identified channel as an index.

12. A dialog engine, for transmitting and receiving text messages, in a messaging dialog, to and from recipient devices via a messaging center, for receiving information from a data source, and for associating and determining the context of the received text messages, the dialog engine comprising:

a plurality of text messaging channels to the messaging center;

a text message generator, for generating text messages for recipient devices, based on information received from the data source;

a channel selector for selecting a text messaging channel to transmit the generated text message over;

a transmitter for transmitting the generated text message to the recipient device over the selected channel;

a receiver for receiving a text message from the recipient device over one of the plurality of text messaging channels; and

a channel and context database, for recording the association of channel and context information for transmitted messages, and for determining the context of received text messages from the receiving text messaging channel and the recorded context and channel associations.

13. The dialog engine of claim 12, wherein the text messages are short message service messages.

14. The dialog engine of claim 12, wherein the plurality of text messaging channels is provided by logically dividing a single text messaging channel.

15. The dialog engine of claim 12, wherein the plurality of text messaging channels is provided by establishing a plurality of unique physical channels.

16. The dialog engine of claim 15, wherein the plurality of unique physical channels is provided by a plurality of SMS modems.
