Abstract

Divulgués dans les modes de réalisation de la présente demande sont, un procédé, un dispositif, et un système d'affichage d'un identifiant de réseau. Dans le procédé, un terminal mesure, selon une signalisation de reconfiguration RRC envoyée par une station de base 4G, un signal envoyé par une station de base 5G ; si la mesure échoue, le terminal mesure de nouveau le signal envoyé par la station de base 5G. Si le signal envoyé par la station de base 5G est mesuré, le terminal affiche un identifiant de réseau et un indicateur d'intensité de signal d'un réseau 5G tout en affichant un identifiant de réseau et un indicateur d'intensité de signal d'un réseau 4G. Dans les solutions techniques fournies dans les modes de réalisation de la présente demande, un terminal peut afficher un identifiant de réseau correspondant et un indicateur d'intensité de signal en fonction des conditions réelles du réseau, et renvoyer des conditions de réseau réel à un utilisateur, permettant ainsi à l'utilisateur, selon les conditions de réseau réel, d'utiliser un service fourni par le terminal, ce qui permet d'améliorer l'expérience de l'utilisateur.
