Abstract

L'invention porte sur un procédé et sur un système d'acquisition de capacité de prise en charge de services téléphoniques sur canaux multi-utilisateurs adaptatifs sur un même créneau (VAMOS) d'un terminal mobile. Un centre de commutation mobile indique, à un sous-système de station de base cible, des informations de capacité de prise en charge de la technologie de services téléphoniques sur canaux multi-utilisateurs adaptatifs sur un même créneau (VAMOS); la capacité du terminal à prendre en charge la technologie VAMOS est acquise par le sous-système de station de base cible conformément aux informations de capacité de prise en charge acquises. Grâce au procédé de l'invention, la capacité du terminal mobile à prendre en charge la technologie de services téléphoniques sur canaux multi-utilisateurs adaptatifs sur un même créneau est acquise par le sous-système de station de base cible, conformément aux informations de capacité de prise en charge rapportées par le terminal mobile, et le sous-système de station de base cible peut distinguer si la technique VAMOS est prise en charge ou non par le terminal mobile, ce qui permet d'utiliser de façon raisonnable la technologie VAMOS. Ainsi la capacité de prise en charge d'utilisateurs téléphoniques par un réseau GSM entier est améliorée sans avoir à augmenter les ressources de fréquence une fois que la technologie VAMOS est utilisée par le réseau GSM.
