    摘要: An improved system and method for communicating Presence Information. According to various embodiments, the sequence of actions undertaken in established Presence procedures are changed, and enhancements are also provided for Watcher information notifications. Upon the initiation of a Presence Service, the Presence Source starts publishing Presence Information about a Presentity using a soft-state approach. Instead of having publication occur first, the Presence Source makes a subscription for the Watcher information first or simply waits until the Presence Server contacts the Presence Source. As a result, publication occurs only when there is a demand therefor.
