Abstract

La présente invention concerne un procédé et un appareil pour transmettre un message de système, utilisé pour résoudre le problème de l'état de la technique dans lequel la transmission de données de service est influencée par l'augmentation de l'occupation des ressources due à la croissance de contenu de messages de système. Le procédé comprend les étapes suivantes : réception, par un terminal, d'un numéro d'index d'une option de message de système valide actuelle dans un ensemble d'options de message de système, le numéro d'index étant envoyé par un appareil côté réseau; et la détermination, par le terminal, en fonction du numéro d'index et de l'ensemble d'options de message de système, d'une option de message de système correspondant au numéro d'index, et la validation de l'option de message de système déterminée, l'option de message de système indiquant au moins un paramètre de message de système et une valeur du paramètre de message de système. Selon la présente invention, un côté réseau permet à un terminal de valider une option de message de système correspondante simplement par notification au terminal d'un numéro d'index d'une option de message de système valide, réduisant ainsi les surdébits de messages de système d'interface radio, et réduisant les surdébits de ressources d'interface radio.
