CA 2622054
To promote efficient transmission of presence update information to a presence service client associated or integrated with a communication client such as an instant messaging (IM) client, a separate computing device may be notified when the communication client becomes dormant. The separate device may buffer presence updates destined for the communication client, each presence update containing information regarding availability of at least one of a set of contacts for intercommunication via said communication client. When the separate device learns that either the communication client has ceased being dormant or that an event has occurred which shall cause the communication client to cease being dormant, the buffered presence updates may be sent to the presence service client. Presence updates within the buffered set may be reconciled to eliminate obsolete information. The result may be a conservation of wireless connection bandwidth or reduction in device power consumption.
