Mobile terminal and network locking method thereof

Abstract

The invention discloses a network locking method of a mobile terminal. The network locking method comprises the following steps of: internally installing an encrypting chip in a mobile terminal, and storing customized information to a user identity module (SIM) card, the encrypting chip and a mobile terminal main chip respectively; and respectively comparing the customized information by the encrypting chip, the mobile terminal main chip and the SIM card after the mobile terminal is started, and blocking communications between the mobile terminal main chip and the SIM card after inconsistence occurs in any comparison. Meanwhile, the invention further discloses a mobile terminal; due to the adoption of the scheme disclosed by the invention, the flexible locking of the network of the mobile terminal can be realized; furthermore, on the conditions that the customized information is operator information or a combination of the operator information and counterpart information in any network, being capable of providing service, of the same operator or the combination of the same operator and the counterpart, the mobile terminal can be operated normally only by the inserting of the SIM card customized by the operator, so that the problem that the inter-modulations of the mobile terminals across the internal networks of the operator must be returned to the manufacturer to lock network again is solved.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a mobile terminal and a network locking method thereof. Background technique [0002] The development and popularization of mobile phones as the most commonly used mobile terminals at present has more and more influence on people's information exchange methods, making mobile phones an indispensable part of people's daily life and work. At present, most mobile phone manufacturers obtain profits by cooperating with operators to customize, and in order to protect their legitimate rights and interests, operators generally require network locks for customized mobile phones, that is, lock certain specific networks, so that Users can only use the services of the operator to protect their own interests. With the development of the internationalized economy, the services provided by many large operators can cover multiple networks. If a certain operator needs to customize a batch of mo...

AI Technical Summary

Problems solved by technology

If a certain operator needs to customize a batch of mobile phones to be sold to different network coverage places, then the mobile phone manufacturer must perform network lock operations on different networks for the mobile phones sold in different places before delivery, which is not only too efficient Low, and the mobile phone after locking the network can only be used under a specific network. If the operator needs to interoperate internally across the network, it must return to the manufacturer to re-lock the network, and the cost is too high
