NETWORK REGISTRATION METHOD AND DEVICE OF MOBILE TERMINAL DURING STARTUP, AND COMPUTER STORAGE MEDIUM

摘要

Disclosed is a network registration method of a mobile terminal during startup, comprising: when a mobile terminal starts up, searching for networks; when a network frequency band where registration is to be performed is a GSM frequency band, determining whether it is the first time that a base station corresponding to the network frequency band where registration is to be performed has sent a position update registration request for registration; if it is the first time that the base station where registration is to be performed has sent the position update registration request, configuring a preset parameter of the position update registration request according to an incorrect subscriber identity and sending the position update registration request to the base station where registration is to be performed; determining whether first registration rejection information is received within a preset time period; if yes, registering at the base station where registration is to be performed again according to a correct subscriber identity; and if not, re-determining a network frequency band where registration is to be performed according to arrangement orders of signal intensities. Also disclosed are a network registration device of a mobile terminal during startup, a computer storage medium, and a mobile terminal.
