Abstract

L'invention concerne un procédé d'établissement d'appel, qui est appliqué à un premier terminal. Lorsque le premier terminal a besoin d'établir un appel avec un second terminal dans un canal commun, le premier terminal détermine des informations concernant un canal privé servant à établir l'appel, le canal privé étant un canal libre différent du canal commun ; et l'appel est établi avec le second terminal par l'intermédiaire du canal privé. Un appel établi par un terminal de communication à l'aide du procédé d'établissement d'appel n'est pas affecté par un appel de groupe direct, ni interrompu par l'appel de groupe direct, et par conséquent l'effet de communication est meilleur.
