Abstract

L'invention concerne un procédé de gestion d'état de terminal, comprenant les étapes suivantes : lorsqu'un premier terminal est situé dans la plage de couverture d'une station de base et a une association de liaison de dispositif à dispositif avec un second terminal, le premier terminal reçoit des informations de traitement associées à un service transmises par le second terminal et/ou un message de signalisation associé à un service transmis par la station de base ; le premier terminal choisit, sur la base des informations de traitement associées à un service et/ou du message de signalisation associé à un service, de se connecter soit au second terminal, soit à la station de base. L'invention concerne également un dispositif de gestion d'état de terminal. L'utilisation de modes de réalisation de la présente invention prend en charge l'accès d'un terminal à un réseau par l'intermédiaire d'un autre terminal, ce qui permet d'augmenter la flexibilité d'un mode de communication et l'efficacité de traitement de service.
