摘要： A system, method and access gateway for minimizing the number of transcodings of a speech signal during a Voice-over-IP (VoIP) conference call in a packet-switched network in which Tandem Free Operation (TFO) is utilized. The system includes a first gateway connecting the first mobile subscriber to the network, a second gateway connecting the second subscriber, and a third gateway connecting the third subscriber. The second gateway sends a message to the first gateway indicating a speech coding mode being utilized between the second gateway and the second subscriber. The third gateway sends a message to the first gateway indicating a speech coding mode being utilized between the third gateway and the third subscriber. When a three-way conference call is initiated, the first gateway encodes the call path to the second subscriber with the speech coding mode being utilized between the second gateway and the second subscriber. The first gateway also encodes the speech signal for the call leg to the third subscriber with the speech coding mode being utilized between the third gateway and the third subscriber.

摘要： Various embodiments are described to provide wireless download services that are more robust than those currently available. Signaling between and among the user equipment (UE) (101) obtaining download service, one or more IMS (IP multimedia subsystem) servers (151), and the download server (161) from which the content is obtained enable an improved level of service. Some improvements that may be realized include guaranteed QoS levels for content downloads, user selection of QoS (in real-time and per content request, possibly), flexible pricing options (e.g., per session, content-based, QoS-based billing), and authentication on a per-content basis.

摘要： A method of delivering data and real-time media from a first mobile terminal to a second mobile terminal when the data is transferred through a packet-switched network, and the real-time media is transferred through a circuit-switched network. The real-time media is passed from the first mobile terminal to the second mobile terminal in a circuit-switched call, and the data is passed in a packet-switched data session. The second mobile terminal associates the circuit-switched call with the data session using binding information, such as an identifier of the first mobile terminal, passed to the second mobile terminal from the first mobile terminal. The real-time media and the data are then presented simultaneously to a user of the second mobile terminal.

摘要： A system and method of providing an integrated wireless telecommunications network including a cellular network portion and a packet-switched network portion. The cellular network portion provides legacy mobile telecommunications functionality to mobile subscribers. The packet-switched network portion is provided for transporting communication traffic, wherein the communication traffic comprises traffic originated from a mobile subscriber, traffic intended for a mobile subscriber, or both. The network also includes a gateway disposed between the cellular network portion and the packet-switched network portion for providing a communication path therebetween. An interworking interface module is provided between the cellular network portion and the packet-switched network portion. The interworking interface module preferably comprises a mobility gateway and an IP client (or proxy), wherein the mobility gateway handles mobility management information and the translation of control signaling information between the cellular network portion and the packet-switched network portion. The IP client handles communication traffic with one or more associated servers disposed in the PSN with respect to, e.g., mobility management, security/authentication, and subscriber services of the mobile subscriber.
