Abstract: A system and method for delivery confirmation of a short message comprising sending the short message to an recipient communication device, determining that an instant message delivery notification (IMDN) is not received, and indicating delivery failure of the short message to the mobile station. In another aspect, if a 202 Accepted message is received, the IM server is subscribed to. Alternatively when a message indicating that an recipient communication device is reachable is received, the service center sends the short message to the communication device. In another alternative, if a recipient absence notification is received the short message is buffered in a service center until the service center receives notification that the recipient communication device is present. Upon receipt of the notification, the service center retransmits the short message, and a successful delivery report is sent when the short message is received by the recipient communication device.

Abstract: A method and apparatus for interworking between push-to-talk over cellular (PoC) systems and instant messaging (IM) systems is provided. An interworking entity that behaves like a PoC client to a PoC server and as an IM client to the IM server is provided. The interworking entity may be implemented as part of the PoC server or the IM server. The interworking entity listens to talk bursts from the PoC server and when it receives a talk burst the interworking entity sends the message to the IM client via the IM server. In an embodiment, the interworking entity listens to talk bursts or audio clips from the IM server and when it receives them, stores them in a temporary storage memory and converts them to a streaming format. The interworking entity then requests the floor from the PoC server, and, once the floor is granted, streams the stored audio clip or talk burst to the PoC server. The PoC server then distributes the clips to the PoC clients.

Abstract: Techniques for archiving data exchanged between a terminal and a wireless communication network during a session are described. Session data may be archived at a network entity in real-time while the session is in progress or may be uploaded to the network entity for archival after the session has terminated. The network entity may archive all data exchanged during the session or only data of the terminal, depending on whether authorization is received from other terminals in the session. The network entity may assign an identifier for the session and may store the identifier and other attributes for the session. During or after the session, the network entity may receive from the terminal a request for all or a portion of the archived data and would then provide the requested data. The network entity may archive a single copy of the session data for all terminals in the session.

Abstract: A communication system facilitates notification of a controller User Equipment (UE) about the changes of session description in a collaborative session by subscribing to a Session Continuity Controller (SCC) Application Server (AS). First, controller UE subscribes to its dialog event package with the SCC AS. Second, SCC AS maintains several dialogs with controller UE, controllee UE(s) and remote UEs within the collaborative session. Third, when there is an updates in the session description of UEs in the collaborative session, SCC AS notifies the controller UE about the change in a SIP NOTIFY request that is constructed by having an XML body with a session description element containing the Session Description Protocol (SDP) of all of the controllee UEs and remote UEs, including media lines and related information such as as the IP addresses of the UEs.
