摘要:
A method of reducing a call set-up time between a pair of H.324-like terminals coupled to one or more telecommunication networks includes providing a first capability identifier in at least one of a non-standard or generic field of a first TCS message, transmitting the first capability identifier from the first H.324-like terminal to the second H.324-like terminal, and receiving, at the first H.324-like terminal, a second capability identifier in at least one of a non-standard or generic field of a second TCS message transmitted from the second H.324-like terminal. The method also includes determining, at the first H.324-like terminal, a mode of operation by utilizing an inference algorithm based upon at least the first capability identifier and the second capability identifier. The method further includes transmitting media from the first H.324-like terminal to the second H.324-like terminal in accordance with the determined mode of operation.
摘要:
A method of initiating a set up process for a call between users with reduced set up times using one or more 3G telecommunication networks. The method includes establishing a bearer channel between a first terminal and a second terminal after a call signaling process and determining, at the first terminal, one or more preferences for a call between the first terminal and the second terminal. The one or more preferences are associated with one or more modes of operation for the call. The method also includes determining a mobile level for operations and interleaving the one or more preferences, the mobile level for operations, and one or more media streams. The method further includes transferring the one or more preferences, the mobile level for operations, and the one or more media streams from the first terminal to the second terminal through a portion of a telecommunication network using the bearer channel.

A method of initiating a set up process for a call between users with reduced set up times using one or more 3G telecommunication networks. The method is provided between at least a pair of H.324-like terminals coupled to the one or more 3G telecommunication networks. The method includes establishing a bearer channel between a first terminal and a second terminal after a call signaling process, transmitting a first FSS message from the first terminal to the second terminal. The first FSS message includes a first preference profile associated with a first mode of operation for the call and a second preference profile associated with a second mode of operation for the call. The method also includes selecting either the first mode of operation or the second mode of operation.

A method of delivering a video ringback media stream to a first terminal includes transmitting a session signaling message from the first terminal to a ringback server, transmitting a session signaling response message from the ringback server to the first terminal, and establishing one or more channels between the ringback server and the first terminal. The method also includes establishing one or more media streams between a content device and the ringback server and processing the one or more media streams in the ringback server to form a video ringback media stream. The method further includes transmitting the video ringback media stream from the ringback server to the first terminal, transmitting a second session signaling message from the ringback server to a second terminal, and transmitting a second session signaling response message associated with answering a call from the second terminal to the ringback server. Transmitting the second session signaling response message is performed after transmitting a session signaling response message.

A method of removing a motion vector from a group of motion vectors used in an encoding process includes providing a list of motion vectors, selecting an initial motion vector from the list of motion vectors, and providing an intermediate motion vector using a motion vector refinement process. The motion vector refinement process uses, in part, the initial motion vector. The method also includes forming a region defined by one or more parameters associated with the initial motion vector and one or more parameters associated with the intermediate motion vector, selecting an additional motion vector from the list of motion vectors, determining that the additional motion vector points into the region, and modifying a state of the additional motion vector.

A multimedia exchange server adapted to communicate multimedia information includes a multimedia gateway adapted to receive a first media from a first network and transmit a second media to a second network. The multimedia exchange server also includes a processor coupled to the multimedia gateway and adapted to provide the second media. The multimedia exchange server further includes a memory coupled to the processor and adapted to store the first media. The first media is stored in the memory for a predetermined period of time, which is greater than a buffering period.

A method of transmitting media to a client by an infrastructure device in a packet-switched network includes receiving a media stream at the infrastructure device. The method also includes determining an adaptation strategy according to at least one of one or more pieces of network information associated with the packet-switched network, one or more pieces of client information associated with the client, or one or more policies. The method further includes adapting the media stream according to the adaptation strategy to produce an output media stream.

A method of establishing a reduced setup time session through a gateway includes receiving a first capability message transmitted from the first terminal to the gateway and receiving a second capability message transmitted from the second terminal to the gateway. The method also includes processing the first capability message and the second capability message to form a third capability message and a fourth capability message. The method further includes transmitting a third capability message from the gateway to the first terminal and transmitting a fourth capability message from the gateway to the second terminal. Moreover, the method includes receiving a first request message transmitted from the second terminal to the gateway and transmitting a second request message from the gateway to the first terminal. Transmitting the second request message is performed independent of receiving the first request message. Additionally, the method includes receiving a first response message transmitted from the second terminal to the gateway and transmitting a second response message from the gateway to the first terminal. Transmitting the second response message is performed in response to receiving the first response message.

A method of providing video ringback services includes receiving, at a VRBT server, a setup message from a terminal originating a call and providing providing a first message from the VRBT server to an MSC. The method also includes establishing a communication session between the terminal originating the call and the VRBT server through the bidirectional bearer, thereafter, providing a video ringback stream from the VRBT server to the terminal originating the call, and receiving a first message from a terminal terminating the call indicating that the terminal terminating the call has answered. The method further includes providing a second message from the VRBT server to the MSC, wherein the second message is interpreted at the MSC as an indication to begin charging for a session and providing a communication path between the terminal originating the call and the terminal terminating the call.
