Parameter processing method and terminal

Abstract

The embodiment of the invention discloses a parameter processing method and a terminal, which are used for recovering and updating a configuration parameter file of a communication terminal. The method in the embodiment of the invention comprises the following steps that: the terminal establishes a fixed partition; the terminal stores a first configuration parameter file in the fixed partition; the terminal reads a second configuration parameter file, wherein the second configuration parameter file is not stored in the fixed partition; the terminal recovers the second configuration parameter file according to the first configuration parameter file if the second configuration parameter file is damaged; or the terminal updates the second configuration parameter file according to the first configuration parameter file if a second version number in the second configuration parameter file is lower than a first version number of the first configuration parameter file. Through adoption of the parameter processing method disclosed by the invention, the terminal can recover and update the configuration parameter file of the communication module from the fixed partition and receive a configuration parameter file issued by a server to update the configuration parameter file of the fixed partition, so that the terminal can obtain an optimal communication service.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a parameter processing method and a terminal. Background technique [0002] At present, the global mobile communication business has a huge market, and more and more mobile terminal operators are participating in it. As users have more and more demands on mobile communications, the technology of using NV parameters can meet many of these demands, so the technology of NV parameters is becoming more and more important. [0003] In the prior art, the communication terminal configures parameters on the communication module side, such as MEID (MobileEquipmentIdentifier, mobile equipment identification code), ESN (ElectronicSerialNumber, electronic serial number), IMSI (InternationalMobileSubscriberIdentificationNumber, International Mobile Subscriber Identification Number), AKEY ( AuthenticationKey, authentication code) and other parameters are integrated into *.qcn ...

AI Technical Summary

Problems solved by technology

[0004] Since the configuration parameters of the communication side of the communication terminal in the prior art are fixed, and the communication terminal is easy to cause the loss and modification of the parameters during the use of the user, so that when the configuration parameters of the relevant communication module side are lost or After being modified, it will cause a series of problems such as the communication terminal cannot recognize the card, have no service, cannot display signals, cannot start the network, or even cannot make calls and access the Internet, which will affect the normal use of customers, cause customer complaints, return and other problems
