Abstract

L'invention concerne un procédé d'accès au réseau et un dispositif d'accès. Des exemples de mise en œuvre du procédé comprennent les étapes suivantes : un premier dispositif d'accès reçoit un premier message, d'un dispositif terminal, le premier message contenant des premières informations d'identification et le premier dispositif d'accès ne prenant pas en charge un protocole de couche supérieure ; et si le dispositif terminal est autorisé à accéder au réseau, le premier dispositif d'accès envoie un second message au dispositif terminal, le second message contenant des secondes informations d'identification qui sont identiques aux premières informations d'identification. Le dispositif terminal selon des modes de réalisation de la présente invention permet de ne pas utiliser une interface radio LTE dans le processus d'accès à un réseau. Cela résout le problème selon lequel, comme tous les dispositifs terminaux utilisent l'interface radio LTE pour accéder au réseau, la charge de l'interface radio LTE est excessivement élevée. La présente invention peut ainsi réduire la charge d'interfaces radio LTE et, partant, l'occurrence de collisions entre des canaux d'accès aléatoire dans des réseaux LTE.
