Abstract: Methods for updating presence information between a first user equipment (UE) and a second UE over a communications network are presented including: on an INVITE message delivery failure to the second UE from the first UE, sending a first PUBLISH message on behalf of the second UE to a presence server by a communications server; sending a NOTIFY message to the first UE by the presence server; and setting a current presence status of the second UE to UNAVAILABLE. In some embodiments, methods further include: if an immediately previous presence status of the second UE is set to AVAILABLE, sending a NOTIFY message to all watchers of the second UE to indicate the current presence status of the second UE. In some embodiments, the first PUBLISH message utilizes a user-agent header to indicate that the communications server originated the first PUBLISH message.

Abstract: A method and device for scheduling signaling and data packets during Push-to-talk (PTT) sessions. An exemplary embodiment of the invention includes scheduling data packets and signaling packets during a push-to-talk session by detecting periods of silence in the talk-burst, inserting signaling packets between the data packets in the periods of silence in the talk-burst; and transmitting the signaling data packet along with the data packets. In another aspect of the invention, downlink signaling packets are suspended during the push-to-talk session.
