The invention relates to a method and a communications arrangement for operating a communications connection between a communications terminal device (KE1) associated with a first participant and at least one first terminal device (KE2) associated with a second participant. For a process running on a second terminal device (RE1) integrating with a first communications terminal device (KE1) to be operated by the first participant, said process being free of functions for controlling the communications connection, at least one piece of information that is reproducible on a terminal device is extracted from a process-produced output (P1) to the second terminal device (RE1). Further, upon initiation of the communications connection between the communications terminal device (KE1) and the first terminal device (KE2), the reproducible information is transmitted to at one of the least one terminal devices (KE2, RE2) associated with the second participant.

Provide are a method and device for exchanging endpoint information and a telepresence endpoint. The method includes that: multiplexing information is exchanged between telepresence endpoints. By means of the present disclosure, the problem in the related art that there are too many ports and multiplexing transmission is unsmooth due to the fact that a multiplexing transmission mode of a traditional session system is still adopted in a telepresence system based on a conventional protocol architecture is solved, and the effect of exchanging the multiplexing information between the telepresence endpoints and therefore multiplexing can be successfully performed in the telepresence system is further achieved.

A multimedia content provisioning device, system and method. The device includes a network interface to communicatively couple to a communications network, to connect to one or more multimedia devices coupled to the communications network, to exchange media processing capabilities between the one or more multimedia devices after establishing a connection therebetween, to generate a list of broadcast media sources and provide the list to each of the one or more multimedia devices in which media processing capabilities are exchanged, to provide a list of broadcast media content receivable from a broadcast media source selected from the generated list at the one or more media devices, and to stream a broadcast media content to the one or more media devices at which a selection from the list of broadcast media content is made, the content being streamed according to the media processing capabilities received therefrom, and to display a multimedia content control user interface at the one or more media devices in which broadcast media content is being streamed.

A collection of methods, which when combined together provide suitable bandwidth resources for real-time content exchange over a satellite-based network, wherein the network employs a reservation-based access scheme, such as but not limited to DVB-RCS. Furthermore, the methods provide suitable bandwidth wherein transmission conditions deteriorate while real-time content is being exchanged and the already allocated resources can no longer be used.

Disclosed are a method and device for scheduling a protocol stack in a telepresence system. The scheduling method includes: a telepresence endpoint acquiring a first state of an H.323 protocol stack and a second state of a third-party protocol stack, herein, the third-party protocol stack is used for performing interaction and negotiation on new characteristic parameters of the telepresence system, and the new characteristic parameters are different from contents for performing capability negotiation through the H.323 protocol stack in the telepresence system; the telepresence endpoint scheduling the H.323 protocol stack and/or the third-party protocol stack to execute a corresponding internal processing action according to a preset scheduling rule based on the first state and/or second state.

A method of notification by an application server of an inability to deliver a message sent by a first terminal destined for a second terminal. The message is transmitted from the first terminal to the second terminal by way of the application server. The application server is configured to store at least one message with a view to a subsequent retransmission when the recipient is not reachable. The method includes: obtaining a message intended for the second terminal, detecting that the second terminal is not reachable, determining an identifier of the sender of the message obtained and of the identifier of the message obtained, and transmitting a notification message to the sender of the message. The message includes at least the identifier of the message obtained and an indication according to which the message obtained has not been delivered.

A method of operating a network server, such as a mobile application gateway, connect devices on a cellular or carrier network with individual networks, such as enterprise voice and data networks or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network, such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise.

Network resources for a call are allocated. The network resources for the call are reserved based on a reservation. The network resources are reserved before any one network resource is committed. If the call is confirmed, then the network resources are committed.

This invention relates to methods for correlating media streams and signaling sessions of services, for example, in a passive monitoring system of a packet-switched network. Furthermore, the invention also relates to an implementation of these methods in hardware and software, and provides a signaling plane probe, a media plane probe and a correlation unit. Moreover, a passive monitoring system comprising one or more of these hardware devices is provided. To correlate media streams and signaling sessions of services, the invention proposes to independently generate correlation keys in a media plane probe for monitored media streams and correlation keys for signaling sessions that are monitored by a signaling plane probe in a fashion that matching correlation keys are generated for a respective service. By identifying reports on the media streams and reports on the signaling session that contain matching correlation keys respectively, the media streams and the signaling streams are correlated in a correlation unit.

A multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) receiver operable to support region of interest (ROI) signaling with a MTSI sender is disclosed. The MTSI receiver can define a requested region of interest (ROI). The MTSI receiver can map the requested ROI to one or more pan, tilt, zoom and focus (PTZF) commands. The MTSI receiver can encode the one or more PTZF commands for transmission to the MTSI sender via real-time transport protocol (RTP) packets, wherein the one or more PTZF commands represent the requested ROI.
