[0070] like image 3 As shown, the first embodiment of the backup recovery method of the NV parameter of the present invention is proposed, and the method includes the following steps:

[0071] S11. Obtain NV parameter data from the NV storage area, and upload the NV parameter data to the server for backup.

[0072] When the mobile terminal is turned on for the first time or when a backup instruction is received, step S11 is performed to perform a backup operation on the NV parameter data.

[0073] Optionally, the mobile terminal reads the parameter information of each NV item in the NV storage area one by one, and creates an NV item list according to the parameter information of the NV item.

[0074] For example: when the operating system of the mobile terminal is the Android system, the interaction between the application processor (AP) of the mobile terminal and the modem (Modem) is used to extract the NV parameters from the NV storage area of ​​the modem. During specific...

[0092] like Figure 5 As shown, the second embodiment of the backup recovery method of the NV parameter of the present invention is proposed, and the method includes the following steps:

[0093] S21. Obtain NV parameter data from the NV storage area, store the NV parameter data locally and upload it to the server for backup.

[0094] In this step S21, the operation of acquiring NV parameter data from the NV storage area is the same as the operation of step S11 in the first embodiment, and will not be repeated here.

[0095] In this embodiment, double backup is performed on the obtained NV parameter data, that is, it is stored locally for local backup, and uploaded to the server for network backup.

[0096] S22. When the NV parameter is abnormal, analyze the availability of locally backed up NV parameter data. It is judged whether the locally backed up NV parameter data is available, and when the locally backed up NV parameter data is available, perform step S23; when the lo...

Abstract

The invention discloses a backup-recovery device and method of NV parameters. The device comprises a backup module used for obtaining NV parameter data from an NY storage region and uploading NV parameter data to a server for backup, a request module used for sending an NY parameter recovery request to the server when NV parameters go abnormal, and a recovery module used for receiving NV parameter data backed up and sent by the server and writing NV parameter data to the NY storage region. Therefore, backup and recovery of NV parameters are automatically directly conducted on a mobile terminal. With no computer and high-pass software tool required, an operation process is simplified and operation efficiency is improved. At the same time, NV parameter data is backed up in the server and are prevented from being damaged due to failure of the mobile terminal. Reliability of backup is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device and method for backup and recovery of NV parameters. Background technique [0002] NV is the abbreviation of NVRAM, the English name is Nonvolatile Random Access Memory, that is, non-volatile random access memory. Once the data is written into the NV, it will not be lost even if the power is turned off, and the original settings will still be retained the next time it is restarted. Usually NV saves the exclusive file system of basic configuration and radio frequency parameters for mobile phones. When the mobile phone is turned off, the data saved in the NV will not be lost. All Qualcomm platforms use NV to save important parameters of the phone. When the NV parameters of the mobile phone are abnormal, the mobile phone will break down and cannot work normally, and can only return to normal after the NV parameters are repaired. [0003] In order to solve the abo...
