Abstract: A communication system and a method can be configured to facilitate the performance of a conference. The system can include a conference organizer terminal and at least two participants' terminals each assigned to respective conference participants who each log in to start a conference on the communication system. The communication system can be configured to calculate a decision situation at a particular point in time of the ongoing conference by analyzing the views expressed by the conference participants during the conference and send data relating to the decision situation for that point in time to the conference organizer's terminal and/or other conference participant terminals for use in facilitating the conference. IN some embodiments, such data can be used to assist the conference participants' in recognizing when there is a consensus made on at least one decision to be made during the conference.

Abstract: The invention concerns a telecommunication system (10) and a computer-implemented method for transferring media data from a first RTC client (30) over a QoS-sensitive network (N1) using the real-time protocol (RTP) to a second RTC client (40), wherein the quality of service is based on different traffic classes and the media data contain a first media type with a first traffic class (QoS1) and a second media type with a second traffic class (QoS2), comprising the following steps: media data, which contain a first media type with a first traffic class (QoS1) and a second media type with a second traffic class (QoS2), are bundled by the first RTC client (30) into second packets (P2), in each second packet (P2), the traffic class (QoS1, QoS2) for each media type is marked in layer 4 and/or layer 5 of the real-time protocol (RTP), the second packets (P2) are transmitted in the direction of the second RTC client (40), either before or during the transfer to the network (N1), the second packets (P2) are unbundled using the markings in layer 4 and/or layer 5 of the real-time protocol (RTP) and then bundled into first packets (P1), each of which has only one of the traffic classes (QoS1, QoS2), and the first packets (P1) are transmitted over the network (N1) to the second RTC client (40).

Abstract: A telecommunication system and a method for transferring media data from a first client over a QoS-sensitive network to a second client. The system and method can permit media data, which contain a first media type with a first traffic class and a second media type with a second traffic class to be bundled by the first client into second packets. In each second packet, the traffic class for each media type is marked in layer 4 and/or layer 5. The second packets can be transmitted toward the second client. Either before or during the transfer to the network, the second packets can be unbundled using the markings in layer 4 and/or layer 5 and then bundled into first packets, each of which has only one of the traffic classes. At least some of the first packets can then be transmitted over the network to the second client.

Abstract: A telecommunications assembly and a method for traversing an application layer gateway firewall during the establishment of an RTC communication connection between an RTC client and an RTC server using a proprietary RTC signalling protocol, wherein the firewall has no specific knowledge of the proprietary RTC signalling protocol. The RTC client and the RTC server can negotiate during the establishment of the RTC communication connection which of the ports of the firewall are required for the data packets to be exchanged via the RTC communication connection, wherein they use at least one standardised message element as a component of the proprietary RTC signalling protocol, with which information relating to the ports to be used can be found by the firewall.
