Title
(EN) FAST INTER SYSTEM PUSH TO TALK OPERATION
(FR) FONCTIONNEMENT DE MESSAGERIE VOCALE INSTANTANÉE INTER-SYSTÈME RAPIDE
Abstract
(EN) Method for establishing a press-to-talk (PTT) session between a first terminal (16) serviced by a first communication system (10) and a second terminal (17) serviced by a second communication system (11), in which the first communication system (10) and second communication system are interconnected by a transmission link (12). The method includes receiving a transmission demand message (TX-DEMAND) from the first terminal (16), sending a transmission granted message (TX-GRANTED) to the first terminal (16) and a transmission demand message (TX-DEMAND) to the second communication system (11) if a communication channel is locally available for the press-to-talk session, receiving transmission packets from the first terminal (16) and relaying the transmission packets to the second communication system (11),and if receiving a transmission granted message (TX-GRANTED) from the second communication system (11) in reply to the transmission demand message (TX- DEMAND), continuing relaying transmission packets to the second communication system (11).
(FR) L'invention concerne un procédé d'établissement d'une session de messagerie vocale instantanée (PTT) entre un premier terminal (16) desservi par un premier système de communication (10) et un second terminal (17) desservi par un second système de communication (11), le premier système de communication (10) et le second système de communication étant interconnectés par une liaison de transmission (12). Le procédé comprend la réception d'un message de demande de transmission (TX-DEMAND) du premier terminal (16), l'envoi d'un message d'autorisation de transmission (TX-GRANTED) au premier terminal (16) et d'un message de demande de transmission (TX-DEMAND) au second système de communication (11) si un canal de communication est disponible localement pour la session de messagerie vocale instantanée, la réception de paquets de transmission du premier terminal (16) et le relais des paquets de transmission au second système de communication (11), et en cas de réception d'un message d'autorisation de transmission (TX-GRANTED) du second système de communication (11) en réponse au message de demande de transmission (TX-DEMAND), la poursuite du relais des paquets de transmission au second système de communication (11).
