METHOD AND DEVICE FOR PROCESSING NETWORK REGISTRATION ANOMALY, STORAGE MEDIUM AND CHIP

This application provides a method for processing a network registration anomaly, an apparatus, a storage medium, and a chip, and relates to the field of communications technologies. In a 5G SA network registration process, if an anomaly occurs in a registration, a terminal device obtains registration failure cause information and a cumulative failure count, to determine whether a condition for ending the registration early is met. If the condition is met, the 5G SA network registration process is ended early, and there is no need to re-attempt for five times according to a protocol, thereby quickly falling back to an LTE network to resume services. Therefore, according to the solution of this application, an abnormal registration can be ended early and another network is registered with if an anomaly occurs in a network registration, to reduce time affected by registration anomaly, thereby solving a problem of frequent registration failures due to a network anomaly or a poor environmental signal in the network registration process, and improving user service experience.
