System and method of triggering and executing active content on a recipient device

1. A system of triggering and executing active content on a recipient device, the system comprising a sender device configured to:

send a trigger message to the recipient device, wherein the trigger message specifies at least one executable file, the executable file comprising active content having multimedia content to be executed by the recipient device, wherein the trigger message comprises a user readable message and is a XMPP (Extensible Messaging and Presence Protocol) message, wherein the executable file is stored on the recipient device or alternatively stored at a further location specified by the trigger message;

determine that the recipient device is not configured to support the trigger message; and

cause the trigger message to be converted to a message supported by the recipient device, wherein the converted message includes an invitation for the recipient device to download the necessary support for the trigger message.

2. A system according to claim 1 , wherein the system comprises a service delivery platform arranged to forward the trigger message from the sender device to the recipient device.

3. A system according to claim 2 , wherein the service delivery platform is configured to check if the recipient device supports the trigger message.

4. A system according to claim 1 , wherein the further location includes an internet store or database from which the executable file may be downloaded.

5. A system according to claim 1 , wherein the executable file is in a compressed file format.

6. A system according to claim 1 , wherein the recipient device is configured to access and execute the at least one executable file.

7. A method of triggering and executing active content on a recipient device, the method comprising the steps of:

configuring, by a sender device, a trigger message, wherein the trigger message specifies at least one executable file, the executable file comprising active content having multimedia content to be executed by the recipient device, wherein the trigger message comprises a user readable message and is a XMPP message, wherein the executable file is stored on the recipient device or alternatively stored at a further location specified by the trigger message;

determining that the recipient device is not configured to support the trigger message and

causing the trigger message to be converted to a message supported by the recipient device, wherein the converted message includes an invitation for the recipient device to download the necessary support for the trigger message.

8. A method according to claim 7 , further comprising the step of checking if the recipient device supports the trigger message.

9. A non-transitory computer readable medium containing software instructions that when executed by a computer cause the computer to:

cause a sender device to configure a trigger message, wherein the trigger message specifies at least one executable file, the executable file comprising active content having multimedia content to be executed by the recipient device, wherein the trigger message comprises a user readable message and is a XMPP message, wherein the executable file is stored on the recipient device or alternatively stored at a further location specified by the trigger message;

determine that the recipient device is not configured to support the trigger message; and

cause the trigger message to be converted to a message supported by the recipient device, wherein the converted message includes an invitation for the recipient device to download the necessary support for the trigger message.

10. The non-transitory computer-readable storage medium of claim 9 , wherein the instructions when executed further cause a service delivery system to forward the trigger message from the sender device to the recipient device.
