Abstract

Un grupo de llamados es conducido en un sistema de comunicaciones inalámbrico, que incluye una pluralidad de unidades de transceptor distribuídas, porejemplo, cabezas de radio en un sistema inalámbrico privado, cada una de las cuales es operativapar a comunicar con terminales en una pluralidad de canales decomunicacion, se transmite un mensaje de origen de grupo de llamados a partir de una terminal de origen, con preferencia, en respuesta a una entrada delusuario en la terminal, de origenc, con mayor preferencia, en respuesta al accionamiento de un dispositivo de presionar para hablar (PTT) en la terminal deorigen. El mensaje de origen de grupo de llamados transmitido es recibido en una unidad de transceptor, en respuesta, unmensaje de de signacion de canal detráfico de grupo de llamados dirigido a un grupo de terminales es transmitido a partir de la unidad de transceptor; el mensaje de designacion de canal detráfico de grupo de llamados transmitido designa un canal detráfico comun. A continuacion se producen las comunicaciones entre las terminales del grupo determinales, con preferencia en modo semi-duplex, en el canal de tráfico comun designado.
