Title (EN) METHOD AND APPARATUS FOR PROVIDING RELIABLE COMMUNICATIONS OVER AN UNRELIABLE COMMUNICATIONS CHANNEL
(FR) PROCEDE ET APPAREIL CONÇUS POUR DELIVRER DES COMMUNICATIONS FIABLES SUR UN CANAL DE COMMUNICATION NON FIABLE
Abstract:
(EN) A method and apparatus for providing reliable data communications over an unreliable voice dispatch communications channel is provided. A voice dispatch channel is established between an originating mobile station (102) and a target mobile station (104). The voice communications channel uses a Push-to- view reliability protocol that utilizes real time protocol data packets and real time control protocol control messages to provide the reliable data communications. Data is sent from the originating mobile station to the target mobile station using the RTP data packets. When the target mobile station determines that it is missing data or that the data is corrupted, it sends a negative acknowledge to the originating mobile station using RTCP control messages.
(FR) L'invention se rapporte à un procédé et à un appareil conçus pour délivrer des communications de données fiables sur un canal de communication par répartition vocale. Un canal par répartition vocale est établi entre une station mobile d'origine (102) et une station mobile cible (104). Le canal de communication vocale utilise un protocole de fiabilité par prise d'image qui utilise des paquets de données de protocole en temps réel (500) et des messages de contrôle de protocole de contrôle en temps réel (600) pour délivrer les communications de données fiables. Des données sont envoyées depuis la station mobile d'origine jusqu'à la station mobile cible au moyen de paquets de données RTP. Lorsque la station mobile cible détermine qu'il s'agit de données manquantes ou que les données sont altérées, elle envoie un accusé négatif à la station mobile d'origine en utilisant les messages de contrôle RTCP.
