Control method and device for startup registration network of mobile terminal

Abstract

The invention discloses a control method for a startup registration network of a mobile terminal. The control method for the startup registration network of the mobile terminal comprises the steps of when the mobile terminal starts up, searching the network, sorting the searched network in various frequency bands according to signal strength to perform networking registration; when the network frequency band to be registered is determined, judging whether the network frequency band to be registered is the GSM frequency band; when the network frequency band to be registered is the GSM frequency band, judging whether the network frequency band to be registered is the pseudo base station frequency band; if yes, re-determining the network frequency band to be registered according to a sort order of the signal strength; and if no, initiating position update registration to a base station corresponding to the network frequency band to be registered. The invention also discloses a control device for the startup registration network of the mobile terminal. According to the method and the device provided by the invention, use security of the mobile terminal under the condition of accessing the GSM network for communication during a startup process is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a control method and device for a mobile terminal to start and register with a network. Background technique [0002] As we all know, because the GSM network does not have a two-way authentication mechanism between mobile terminals and base stations like 3G and 4G networks, it is a network that implements a one-way authentication mechanism for mobile terminals. Under this authentication mechanism, the fake base station can allow GSM users to access by imitating the base station, and push information to the user through various methods such as SMS, telephone, and Internet access, which not only interferes with the user, but also affects the user's security and privacy. etc. cause harm, and greatly deplete public spectrum resources; making mobile terminals have security risks in the state of accessing the GSM network for communication.
