Abstract

A system and method for indicating when a message recipient is unavailable to receive messages in an instant messaging network, for example, being engaged in telephone communications on the receiving device, where disruption of service is likely or imminent. When notification of an inbound call is received the communications device transmits via the GPRS connection a packet indicating the impending unavailability of the recipient for messages, prior to disruption of the GPRS data stream to establish a GSM connection.

Claims

1. A method of indicating a user'"'"'s presence status in a messaging network, comprising the steps of:

detecting an impending presence event at a user'"'"'s mobile communications device; and

,

immediately before the occurrence of the presence event, transmitting to at least one status recipient at least one status packet indicating the user'"'"'s presence on the messaging network upon occurrence of the event,

wherein the user'"'"'s mobile communications device is capable of both voice communication for placing and receiving telephone calls and packet data communication, and wherein the presence event comprises a suspension of packet data communication at the user'"'"'s mobile communications device due to the use of said device for a telephone call.

2. The method of claim 1, wherein the step of detecting the impending presence event comprises receiving one of:

an indication that an outgoing telephone call is about to be placed using the user'"'"'s mobile communications device;

or

a notification of an incoming telephone call at the user'"'"'s mobile communications device.

3. The method of claim 2, wherein the user'"'"'s mobile communications device comprises a Class B mobile communications device capable of voice communication when connected to a GSM network and capable of packet data communication when connected to a GPRS network.

4. The method of claim 3, wherein the notification of an incoming telephone call is received over a GSM control channel.

5. The method of claim 1, wherein the at least one status recipient comprises at least one of a presence service on the messaging network, a further mobile communications device, and at least one message sender designated by the user.

6. The method of claim 1, wherein the presence event further comprises loss of signal coverage at the user'"'"'s mobile communications device, and the step of detecting said impending presence event comprises detecting the weakening of a communications carrier signal strength from the messaging network to a predetermined threshold.

7. The method of claim 1, wherein the presence event further comprises entry into signal coverage at the user'"'"'s mobile communications device, and the step of detecting said impending presence event comprises detecting the increase of a communications carrier signal strength from the messaging network above a predetermined threshold.

8. The method of claim 1, wherein the at least one status packet is transmitted over a packet data channel.

9. The method of claim 1, wherein the at least one status packet is transmitted in an SMS message.

10. The method of claim 1, further comprising the steps of generating at least one further status packet indicating the user'"'"'s presence on the messaging network and transmitting the at least one further status packet to the at least one status recipient on a periodic basis.

11. The method of claim 8, wherein the at least one status packet is generated at the user'"'"'s mobile communications device.

12. The method of claim 1, wherein the at least one status packet comprises at least one of a reason and a redirection or forwarding instruction.

13. A computer-readable medium comprising code executable by a mobile communications device for causing the mobile communications device to carry out the method of claim 1.

14. A signal-bearing medium embodying machine-readable instructions executable by a mobile communications device to perform the method of claim 1.

15. A mobile communications device capable of both voice communication for placing and receiving telephone calls and packet data communication in a system for indicating presence status in a messaging network, the system comprising at least one status recipient for receiving status packets indicating the presence of a user of the mobile communications device on the messaging network, the mobile communications device comprising:

a device processor for detecting an impending presence event at the mobile communications device and for generating at least one status packet indicating the presence of the user of the mobile communications device on the messaging network upon occurrence of the event, the presence event comprising a suspension of packet data communication at the mobile communications device due to the use of said device for a telephone call, and

a transmitter for sending the at least one status packet to at least one status recipient immediately before the occurrence of the presence event.

16. The mobile communications device of claim 15, wherein the device processor is configured to detect the impending presence event by detecting an indication that an outgoing telephone call is about to be placed using the mobile communications device, or detecting a notification of an incoming telephone call at the mobile communications device.

17. The mobile communications device of claim 16, wherein the mobile communications device comprises a Class B mobile communications device capable of voice communication when connected to a GSM network and capable of packet data communication when connected to a GPRS network.

18. The mobile communications device of claim 15, wherein the at least one status recipient comprises at least one of a presence service on the messaging network, a further mobile communications device, and at least one message sender designated by the user.

19. The mobile communications device of claim 15, wherein the at least one status packet is transmitted over a packet data channel.

20. The mobile communications device of claim 15, wherein the at least one status packet is transmitted in an SMS message.

21. The mobile communications device of claim 15, wherein the device processor is further configured to generate at least one further status packet indicating the user'"'"'s presence on the messaging network on a periodic basis for transmission by the transmitter to the at least one status recipient.

22. The mobile communications device of claim 15, wherein the at least one status packet comprises at least one of a reason and a redirection or forwarding instruction.
