A method and apparatus for providing an efficient dormant mode for push-to- talk communication devices (102, 104, 106) in a group communication network (100) provides for determining whether the communication device has been inactive for a predetermined first time period and, if so, causing the communication device to enter a control-hold mode, wherein the communication device maintains its dedicated traffic channel. The method further includes the steps of determining whether the communication device has been in the control-hold mode for a predetermined second time period and, if so, causing the communication device to enter a dormant mode, wherein the communication device releases its dedicated traffic channel. The method and apparatus further provides for causing the communication device to cache its service configuration state before entering the dormant mode.
L'invention porte sur un procédé et un appareil permettant efficacement de mettre en sommeil les dispositifs de télécommunications en alternat (102, 104, 106) d'un groupe de (100) de communication en déterminant si l'un des dispositifs est resté inactivé pendant une première période prédéterminée, et, si c'est le cas, en plaçant le dispositif de communication en mode veille ou il conserve son canal de trafic spécifique. Le procédé consiste ensuite à déterminer si le dispositif de communication est resté en mode veille pendant une deuxième période déterminée, et si c'est le cas, à mettre le dispositif de communication en sommeil, ce qui libère le canal de trafic spécifique. Le procédé et l'appareil permettent en outre de mettre en mémoire l'état de configuration de service du dispositif avant sa mise en sommeil.
