ABSTRACT:
A network node provides presence updates to mobile users. The node reduces the amount of network traffic by eliminating the need for explicit messaging used to inform a user of presence updates. Additionally, the node reduces network traffic by consolidating presence updates, and sending the user only changed portions of the presence information.
