Abstract

Methods, devices, and computer readable media for switching communications from a first messaging protocol/service to a second messaging protocol/service by use of messaging information being embedded in a header of a first message of the first messaging protocol/service to enable the recipient to contact the sender over the second messaging protocol/service, is provided.

Claims

1. A method of switching a mode of communication from a first messaging protocol to a second messaging protocol for communications between a first user device and a second user device, the method comprising:

communicating a first message containing messaging information for the second messaging protocol, by the first user device to the second user device using the first messaging protocol; and

using the messaging information, after the communicating of the first message, to switch the mode of communication to the second messaging protocol when at least one of the first user device and the second user device communicates one or more subsequent messages.

2. The method of claim 1, wherein:

said communicating comprises sending the first message from the first user device; and

said switching the mode of communication to the second messaging protocol comprises receiving a second message of the second protocol at the first user device and thereafter communicating using the second messaging protocol.

3. The method of claim 1, wherein:

said communicating comprises receiving the first message at the second user device; and

said switching the mode of communication to the second messaging protocol comprises extracting the messaging information and transmitting a second message using the second messaging protocol at the second user device and thereafter communicating using the second messaging protocol in accordance with the messaging information.

4. A method of claim 1 further comprising before communicating:

determining from predetermined messaging options whether messaging between the first user device and the second user device is permitted to be switched from the first messaging protocol to the second messaging protocol.

5. The method of claim 1, wherein the first messaging protocol comprises a short message service (SMS) protocol, and the second messaging protocol comprises a peer to peer (P2P) messaging protocol.

6. The method of claim 5, wherein the peer to peer messaging protocol is an email protocol.

7. The method of claim 1, wherein the messaging information is in a user data header of the first message.

8. The method of claim 1, wherein the messaging information comprises a personal identification number for use in peer to peer messaging.

9. The method of claim 1, wherein the second messaging protocol is automatically selected by the first user device from a set of one or more possible messaging protocols using at least one of expense and reliability as a selection criteria.

10. The method of claim 1, wherein the communicating and switching takes place automatically and transparent to users of the first and second user devices.

11. The method of claim 1, wherein the messaging information includes information identifying a device identifier (ID) of the first user device according to other messaging protocols for which the second user device is capable of communicating.

12. A user device comprising:

a receiver configured to receive messages;

a transmitter configured to send messages; and

a processor communicatively coupled to the receiver and the transmitter, the processor configured to;

communicate a first message containing messaging information for a second messaging protocol, using the first messaging protocol; and

using the messaging information for the second messaging protocol, after communicating the first message, to switch to the second messaging protocol when the transmitter is sending one or more subsequent messages.

13. A computer readable medium comprising stored instructions for execution at a first user device, the instructions implementing a method of switching a mode of communication from a first messaging protocol to a second messaging protocol for communications between the first user device and a second user device, the method comprising:

communicating a first message containing messaging information for the second messaging protocol, using the first messaging protocol; and

using the messaging information, after communicating the first message, to switch the mode of communication to the second messaging protocol when at least one of the first user device and the second user device communicates one or more subsequent messages.

14. A method of switching a mode of communication from a first messaging protocol to a second messaging protocol, the method comprising:

communicating a first message according to the first messaging protocol, the first message containing messaging information for the second messaging protocol; and

using the messaging information to communicate a subsequent message according to the second messaging protocol.

15. The method of claim 14, wherein the messaging information is used to communicate a subsequent message according to the second messaging protocol in response to the second messaging protocol becoming preferable to the first messaging protocol.
