Abstract

A method for detecting and transporting dynamic presence information over a wireless and wireline communications network comprises determining client device capabilities relating to user presence information that may be obtained from the client device and determining a presence configuration of the client device. The presence configuration defines information to be provided to a presence agent. The presence configuration also defines one or more action to be performed upon notification of an event occurrence. The method also includes collecting dynamic presence information based at least in part on the client device capabilities and the presence configuration.
