Problems solved by technology

The problem with this method is that the terminal must be divided into a storage area that can only be programmed once or a programmable read-only memory (Programmable Read Only Memory, referred to as PROM) chip must be added separately, and the implementation cost is high, and the judgment of this method focuses on As for the result of the change, it is necessary to further prevent the changed terminal from being used after judging that the program has been illegally changed. There is a lag, and it is impossible to prevent the terminal from being changed by the software in a real sense.
[0007] At present, there is no technical solution that can effectively prevent the terminal from being changed by software

Embodiment Construction

[0026] Functional Overview

[0027] Aiming at the problem that the terminal is easily changed by software in the related art, the present invention aims at the characteristics that the software change needs to go through the data line, the built-in data interface of the mobile terminal and the data line connected to the interface, by implementing the tool software (software for performing update) The one-way / two-way handshake with the mobile terminal software (software to be updated), and the mobile terminal software's verification of the new mobile terminal software (software that needs to be replaced with the mobile terminal software), from the process of illegal modification rather than illegal modification As a result, the possibility of the software of the mobile terminal being illegally updated is eliminated, so that the mobile terminal can be protected in a non-destructive manner to the greatest extent.

Abstract

The invention discloses an updating method and a mobile terminal of mobile terminal software. The method comprises the following steps: the mobile terminal software and / or tool software for updating the mobile terminal software shake hands according to the enciphered hand-shaking data sent by the counterpart; and under the condition of successful hand-shaking, the mobile terminal software or tool software carries out verification for new mobile terminal software according to pre-enciphered characterization identifiers of the mobile terminal software and characterization identifiers of the new mobile terminal software, and determines whether to allow updating according to verification result. Through introducing two authentications of hand-shaking data and characterization identifiers, the method greatly eliminates possibility that the terminal is modified by software, avoids terminal unlock and machine-locking phenomena in relevant technology, overcomes the disadvantages of the prior unlocking and machine-locking technology, ensures terminal safety to the utmost extent, and effectively maintains benefit of an operator.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a mobile terminal software updating method and the mobile terminal. Background technique [0002] At present, the global mobile communication market is developing very rapidly, and the competition among various operators is also very fierce. Especially in the terminal product market, in order to attract users, various operators have launched a series of promotional policies to sell terminals to users at great discounts, and some operators even give terminals to users for free. [0003] However, out of consideration of their own interests, operators usually take a series of restrictive measures. Among them, the more common restriction method is to control the terminal, so that the terminal can only be used under the network of the operator that gives it preferential treatment, or must insert a certain specified card to make the terminal in a usable state. Usually, s...
