Abstract

Les modes de réalisation de la présente invention concernent un procédé permettant de résoudre une interférence de norme de réseau, un terminal, un dispositif de réseau et un support de stockage, se rapportant au domaine des communications. Le procédé comprend les étapes suivantes : s'il existe une interférence entre des normes de réseau correspondant à au moins deux cartes SIM dans un terminal, le terminal envoie une demande d'ajustement de ressources à un dispositif de réseau correspondant à une carte SIM cible dans les au moins deux cartes SIM, la demande d'ajustement de ressources comprenant des informations auxiliaires de solution d'interférence ; le dispositif de réseau reçoit la demande d'ajustement de ressources envoyée par le terminal, et ajuste, en fonction des informations auxiliaires de solution d'interférence, des ressources temps-fréquence configurées pour la carte SIM cible. Le procédé décrit dans les modes de réalisation de la présente invention est capable de résoudre le problème d'interférence existant entre des normes de réseau, ce qui facilite l'amélioration de la qualité de communication d'un terminal à multiples canaux à cartes multiples.
