Abstract

Selon des modes de réalisation, la présente demande s'applique au domaine technique des communications, et concerne un procédé d'enregistrement IMS, un dispositif terminal et un support de stockage. Le dispositif terminal reçoit un message de rejet de session PDU dans un réseau 5G. Le message de rejet de session PDU est utilisé pour indiquer que l'enregistrement IMS par le dispositif terminal dans le réseau 5G est rejeté, et comprend une valeur de cause de rejet. Lorsque le dispositif terminal se replie sur un réseau 4G, et qu'il est déterminé qu'aucune information d'indication de relance n'est acquise et que la valeur de cause de rejet est une valeur de cause prédéfinie, l'IMS est enregistré dans le réseau 4G. Étant donné que le dispositif terminal peut immédiatement lancer l'enregistrement IMS après s'être replié sur réseau 4G, la vitesse d'enregistrement IMS est améliorée.
