METHOD AND TELECOMMUNICATIONS ARRANGEMENT FOR TRANSFERRING MEDIA DATA HAVING DIFFERING MEDIA TYPES VIA A NETWORK SENSITIVE TO QUALITY OF SERVICE

摘要

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 (QoS 1) 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), andthe first packets (P1) are transmitted over the network (N1) to the second RTC client (40).

1. A computer-implemented method for transferring media data from a first real-time communication (“RTC”) client over a quality of service-sensitive (“QoS-sensitive”) network using a real-time protocol (RTP) to a second RTC client, wherein a quality of service is based on different traffic classes and wherein the media data contain a first media type with a first traffic class and a second media type with a second traffic class, comprising the following steps:
bundling media data, which contain the first media type with the first traffic class and the second media type with the second traffic class, by the first RTC client into second packets, marking, in each second packet, the traffic class for each media type in at least one of layer 4 and layer 5 of the real-time protocol, transmitting the second packets in the direction of the second RTC client, either before or during the transfer to the network, unbundling the second packets using the markings in at least one of layer 4 and layer 5 of the real-time protocol and then bundling the second packets into first packets, each of which has only one of the first traffic class and the second traffic class, and transmitting the first packets over the network to the second RTC client.
