  • the MME allocates a temporary identifier of the wireless network to each base station, and each base station performs scrambling processing on the communication data according to the temporary identifier of the wireless network allocated by the MME.
  • the MME reserves a part of the temporary identifier of the wireless network, but does not allocate, but is used for group call communication.
  • these reserved wireless network temporary identifiers are not used for LTE communication scrambling, but are used for scrambling group call data during group call communication.

Abstract

La présente invention concerne un procédé d'établissement d'appel de groupe, appliqué à un appareil de gestion de mobilité. L'appareil de gestion de mobilité sélectionne, parmi tous les identifiants temporaires de réseau radio pouvant être attribués, un nombre défini d'identifiants temporaires de réseau radio pour une communication d'appel de groupe. Le procédé consiste : à recevoir une instruction d'établissement d'appel de groupe, et à analyser l'instruction afin d'obtenir des informations de configuration d'appel de groupe ; conformément aux informations de configuration d'appel de groupe, à réaliser une analyse afin d'obtenir une station de base impliquée dans un appel de groupe ; conformément aux identifiants temporaires de réseau radio sélectionnés, à définir un identifiant temporaire de réseau radio de groupe pour l'appel de groupe ; à envoyer les informations de configuration d'appel de groupe et les informations d'identifiant temporaire de réseau radio de groupe à la station de base impliquée dans l'appel de groupe, de telle sorte que la station de base impliquée dans l'appel de groupe crée l'appel de groupe conformément aux informations de configuration d'appel de groupe, et réalise un brouillage sur les données d'appel de groupe transmises conformément à l'identifiant temporaire de réseau radio de groupe. Concernant un appel de groupe créé à l'aide de la solution technique, un identifiant temporaire de réseau radio de groupe de chaque cellule est identique, et une extrémité d'utilisateur peut réaliser rapidement une analyse de données lors de la réception de données sur un ensemble de cellules.
