Abstract: An apparatus and method for generating compressed SIP messages from full sized SIP messages and vice versa in order to decrease call set up time in an IP based communication system. During registration of a device, the invention caches the device's static information in the core network in a "Registrar/Location Server." Subsequently, during call set up, the device transmits its dynamic information to the SIP Agent in a compressed SIP message over an air interface. The SIP Agent retrieves the static information (from the Registrar/Location Server) along with the dynamic information in the compressed SIP message to generate a full sized SIP message. The SIP Agent forwards the full sized SIP message to a SIP Proxy, which is then transmitted to the IP system. Likewise, when a full sized SIP message is received from the IP system, the message is forwarded to the SIP Agent to generate a compressed SIP message for ultimate transmission to the device over the air interface.

Abstract: A presence agent (101) receives a message with a request for a status of one or more entities. The presence agent (101) determines the status of the entities, and transmits a message with the status of the entities. Transmitting the message includes initiating a connection to a communication device (107). A watcher (103) monitors the status of the entities, and provides updated information regarding the status to the users. The watcher (103) receives a request for a status of entities, determines the status of the entities, and transmits, in response to receipt of the request, a response indicating the status. A communication device (107) transmits a message having a request for status of entities. The communication device receives, from a connection initiated by a communication network (105), a message with a status of the entities, and processes the status of the entities, in response thereto.
