Abstract
A method for a watcher to receive presence information. The method includes the watcher requesting presence information from a presence access layer and then disconnecting from the presence access layer. The method further includes the presence access layer receiving the requested information through a persistent session with a presence server, storing the requested information, and delivering the requested information to the watcher after the watcher reconnects to the presence access layer.
