Abstract

Selon des modes de réalisation, la présente invention concerne un procédé, un appareil et un système de communication. Le procédé comprend les étapes suivantes : un dispositif terminal génère des premières informations, les premières informations comprenant des informations d'identification d'un premier ARN et des secondes informations, les secondes informations étant utilisées pour déterminer des informations temporelles du dispositif terminal dans le premier ARN ; le dispositif terminal envoie les premières informations à un dispositif réseau. Dans la solution, le dispositif terminal enregistre des informations d'ARN à travers lesquelles passe le dispositif terminal, les informations comprenant des informations capables de représenter la situation de campement du dispositif terminal dans les ARN (c'est-à-dire, les secondes informations). Le dispositif réseau, après réception des informations d'ARN rapportées par le dispositif terminal, peut savoir quel ARN rencontre un problème anormal quant au temps de campement du dispositif terminal, et détermine ainsi si la configuration de taille d'un certain ARN est raisonnable, de telle sorte que le dispositif réseau peut configurer une plage d'ARN appropriée pour le dispositif terminal. Les surdébits du dispositif terminal et du dispositif réseau sont réduits.
