Abstract

La présente invention concerne un procédé de traitement côté service destiné à un service limité à une zone. Le procédé consiste : à recevoir un message d'initiation de service envoyé par un terminal utilisateur de grappe, le message transportant des informations ECGI, une identification d'utilisateur, une identification de groupe et une identification de service ; à déterminer si le terminal utilisateur initie un service à l'intérieur d'une zone limitée ; lorsque le terminal utilisateur appartient à la zone limitée, à établir un contexte de service conformément au type du service ; et à notifier des terminaux utilisateurs, dans le groupe, à l'intérieur de la zone limitée afin de rejoindre le service. L'invention concerne également un procédé de traitement de terminal utilisateur destiné à un service limité à une zone, un serveur utilisateur de grappe et un terminal utilisateur de grappe. Dans la présente invention, au moyen du préréglage d'une zone limitée dans un serveur MCPTT, du rapport par un utilisateur de grappe des informations de position ECGI en temps réel, et du maintien par un GCSE AS des instances d'élément de groupe à l'intérieur et à l'extérieur d'une zone de service, la gestion des services de zone de grappe est achevée, et la demande destinée à des services de zone limitée dans un service MCPTT est satisfaite.
