Description
Technical field
The present invention relates to the wireless communication technique field, be specifically related to a kind of NV backup and recovery method based on high-pass platform.
Background technology
NV is the abbreviation of NVRAM, and English name Nonvolatile random access memory is nonvolatile random access memory.It is the exclusive file system that mobile phone is preserved basic configuration and radio frequency parameter, and when mobile phone shutdown, the data that are kept in the NV can not lost.All high-pass platforms all adopt NV to preserve the important parameter of mobile phone, the data such as employing NV preservation parameter are not only convenient and swift, and be convenient to upgrade or revise, because the product of high-pass platform is widely used in market, various instruments for high-pass platform also have a lot, because there is not parameter backup, in case the improper upgrading of user or the special-purpose instrument of employing crack, will cause to the significant data in the mobile phone loss that can't recover, serious even cause mobile phone to use, the present invention is directed to this shortcoming, the mode that adopts hidden partition is kept at the important parameter among the NV in the subregion that the user can't access, in case original NV data change, the data that software will be kept at hidden partition automatically recover, and have guaranteed the security of mobile phone.
Summary of the invention
The purpose of this invention is to provide a kind of NV backup and recovery method based on high-pass platform, to overcome above shortcomings in the at present existing method.
The objective of the invention is to be achieved through the following technical solutions:
A kind of NV backup and recovery method based on high-pass platform is used for data in the NV system of mobile phone are backed up, and said method comprising the steps of:
(1) starting hand-set is installed mobile phone terminal system initial software in mobile phone, this software creates independently NV hidden partition in mobile phone, and the NV hidden partition only is the system partitioning of NV backup, and described NV hidden partition can not be by user and common system program access;
(2) take the NV parameter as benchmark, be every mobile phone debugging calibration to factory, generate the NV parameter configuration corresponding to concrete each production line mobile phone terminal, and with its input handset terminal;
(3) use the DIAG instruction, send the signal that begins to back up;
(4) after NV backup TASK receives the signal of DIAG instruction, all NV data are backuped to the NV hidden partition;
(5) after the backup, in the mobile phone file system, set up the successful mark of backup, finish backup;
Whether (6) utilize the testing mechanism of NV restore task, will lose the NV data in the mobile phone and detect, mobile phone normally uses if do not lose then; If after losing, then begin to carry out mobile phone NV data and recover, data recover to comprise manual reset mode and automatic reset mode;
(7) Backup Data with hidden partition reverts to user data subregion in the cell phone system; And
(8) recover the rear mark that data are successfully recovered that creates, just can normally use mobile phone.
Further, described manual reset mode may further comprise the steps:
1) user triggers the NV parameter recovery tasks of mobile phone terminal by carrying out the DIAG instruction of customization;
2) Backup Data with hidden partition reverts to user data subregion in the cell phone system.
Further, described automatic reset mode may further comprise the steps:
1) the NV restore task detects NV reduction marker bit, determines whether to carry out NV and recovers, if need to recover, then carries out recovery tasks;
2) in rejuvenation, handling procedure will check the NV data in the filtered set, filters collection if exist, and after then filtering, carries out data and recovers, and described filtration collection will be used for adding some NV data item; And
3) Backup Data with hidden partition reverts to user data subregion in the cell phone system.
Beneficial effect of the present invention is: the present invention goes for any high-pass platform, processes simply, and interface is few, safe, be convenient to mobile phone terminal manufacturer follow-up maintenance, avoided simultaneously user's operation error to cause mobile phone parameters to be damaged, and can keep the NV configuration data of latest software update.
Description of drawings
The below is described in further detail the present invention with reference to the accompanying drawings.
Fig. 1 is the process flow diagram of the described a kind of NV data backup based on high-pass platform of the embodiment of the invention;
Fig. 2 is the described a kind of process flow diagram that recovers based on the NV data of high-pass platform of the embodiment of the invention.
Embodiment
As shown in Figure 1, the described a kind of NV data back up method based on high-pass platform of the embodiment of the invention is used for data in the NV system of mobile phone are backed up, and said method comprising the steps of:
(1) starting hand-set is installed mobile phone terminal system initial software in mobile phone, this software creates independently NV hidden partition in mobile phone, and the NV hidden partition only is the system partitioning of NV backup, and described NV hidden partition can not be by user and common system program access;
(2) take the NV parameter as benchmark, be every mobile phone debugging calibration to factory, generate the NV parameter configuration corresponding to concrete each production line mobile phone terminal, and with its input handset terminal;
(3) use the DIAG instruction, send the signal that begins to back up;
(4) after NV backup TASK receives the signal of DIAG instruction, all NV data are backuped to the NV hidden partition; And
(5) after the backup, in the mobile phone file system, set up the successful mark of backup, finish backup.
As shown in Figure 2, the described a kind of NV data reconstruction method based on high-pass platform of the embodiment of the invention is used for data in the NV system of mobile phone are recovered, and is further comprising the steps:
Whether (1) utilize the testing mechanism of NV restore task, will lose the NV data in the mobile phone and detect, mobile phone if do not lose then, if after losing, then begin to carry out mobile phone NV data and recover if normally using;
(2) data recover to comprise manual reset mode and automatic reset mode, and described manual reset mode is further comprising the steps: 1) user triggers the NV parameter recovery tasks of mobile phone terminal by carrying out the DIAG instruction of customization; 2) Backup Data with hidden partition reverts to user data subregion in the cell phone system.Described automatic reset mode is further comprising the steps: 1) the NV restore task detects NV reduction marker bit, determines whether to carry out NV and recovers, if need to recover, then carries out recovery tasks; 2) in rejuvenation, handling procedure will check the NV data in the filtered set, if there is filtered set, after then filtering, carries out data and recovers, and described filtration collection will be used for adding some NV data item; 3) Backup Data with hidden partition reverts to user data subregion in the cell phone system;
