Title (EN) MULTIMEDIA AND MULTISERVICE CALLS IN MOBILE NETWORK
(FR) COMMUNICATIONS MULTIMEDIA ET MULTISERVICE DANS UN RESEAU MOBILE
Abstract: front page image
(EN)One common traffic channel is allocated to a multiservice call which requires simultaneous transmission of two or more different information flows apart from one another. This common traffic channel is divided into a transparent and a non-transparent sub-channel. The transmitting end is provided with a multiplexer (73) which multiplexes the different information flows (75, 76) to the common traffic channel. The receiving end is provided with a demultiplexer (74) which demultiplexes the signal received from the common traffic channel back into separate information flows (75, 76). The transparent sub-channel is used for transmitting time-critical information, such as video and audio, which does not allow the use of an error correction protocol based on retransmission, and the non-transparent sub-channel can be used for transmitting less time-critical information, such as data files, which allows the use of error correction based on retransmission.
(FR)Dans cette invention, un canal de trafic commun est attribué à une communication multiservice exigeant une transmission simultanée d'au moins deux flux d'informations différents, distincts l'un de l'autre. Ce canal de trafic commun est divisé en un sous-canal transparent et un sous-canal non transparent. L'extrémité émettrice est pourvue d'un multiplexeur (73) qui multiplexe les différents flux d'informations (75, 76) pour le canal de trafic commun. L'extrémité réceptrice est pourvue d'un démultiplexeur (74) qui démultiplexe le signal reçu du canal de trafic commun, pour obtenir à nouveau des flux d'informations distincts (75, 76). Le sous-canal transparent sert à transmettre des informations temporairement critiques, telles que la vidéo et l'audio, ce qui ne permet pas l'utilisation d'un protocole de correction d'erreurs à base de retransmission. Le sous-canal non transparent peut servir à transmettre des informations temporairement moins critiques, telles que des fichiers de données, ce qui permet l'utilisation d'une correction d'erreurs à base de retransmission.
