FIELD: processing of anomalies during registration in a communication network.
SUBSTANCE: method includes: initiation, by the terminal device, of the M-th registration request to the autonomous communication network of the fifth generation (5G SA), where M is a positive integer less than 5; if the cumulative number M of failures is not less than the first predetermined number of failures corresponding to the first predetermined cause information, executing, by the terminal device, the first processing policy corresponding to the first predetermined cause information, where this first processing policy comprises: ceasing to initiating a 5G SA registration request communication, and initiating a registration request to a second communication network other than the 5G SA communication network. Therefore, the abnormal registration situation can be quickly terminated and registered with another communication network in the event of an anomaly occurring during registration with the communication network, so as to reduce the time affected by the registration anomaly.
EFFECT: eliminating frequent registration failures due to anomalies in the communication network or poor signal passing during registration in the communication network and improving the quality of user service.
