Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A system and method in a wireless telecommunication network for placing on hold an ongoing circuit-switched voice call between a first party and a second party, and conducting a packet-switched data session between the second party and a third party. An enhanced Gs interface between a Serving GPRS Support Node (SGSN) in a packet-switched network and a Mobile Switching Center (MSC) in a circuit-switched network enables messages to be passed that enable the second party to place the first party on hold and either accept an incoming data session from the third party or originate a data session to the third party. When the data session is completed, the MSC is notified, and the voice call is resumed between the first party and the second party.
