Description

Internet of things equipment 5G parameter storage and recovery method and internet of things equipment

Technical Field

The invention relates to a 5G parameter processing technology of Internet of things equipment, in particular to a method for saving and recovering 5G parameters of the Internet of things equipment and the Internet of things equipment.

Background

The internet of things device 5G parameter is stored in a work partition as an NV value, and data stored in the work partition is not easy to lose. However, the high-pass platform has a disadvantage in operating the work partition, and when the data in the work partition fails to be operated, there is no mechanism for restoring to the factory state. NV refers to non-volatile memory, abbreviated NVRAM, which is system hardware used to hold some parameter values used in various modules.

The high-pass platform NV system mainly involves two partitions, a working partition for NV and a storage partition for the initialization values of NV parameters.

The work partition for the current NV is defined by the high-pass platform as modestm 1 or modestm 2, which is equivalent to the modestm 1 partition or modestm 2 partition in work. The 5G parameters are always stored in the modestm 1 partition when leaving the factory, and the router continuously performs read-write interaction with the modestm 1 partition in the running process.

The partition storing the NV parameter initialization value is an FSG partition, and the high-pass platform creates an image file containing the NV parameter initialization value and downloads the image file into the FSG partition.

As shown in FIG. 2, the high-pass platform judges whether the FSG partition copy to the modestm 1 partition is empty according to the judgment, and if the current NV working modestm 1 partition is empty, the NV parameter initialization value in the image file in the FSG partition is updated to the modestm 1 partition.

As shown in fig. 1, after the general 5G device first downloads software in an empty disk, because the modestm 1 partition is empty, the NV parameter initialization value in the FSG partition is written into the modestm 1 partition. Calibration parameters, IEMI, etc. 5G critical parameters were then written to modemst1 partition at the production ring, resulting in a failure to erase modemst1 partition later. Since the modestm 1 partition cannot be erased, the empty state will no longer occur, and the data for the FSG partition will no longer have a chance to be written into the modestm 1 partition. The reason why the modestm 1 partition cannot be erased is that the partition cannot be read and written, but after the data of the partition is erased, calibration parameters written in factory, IEMI and other 5G important parameters are lost. The 5G important parameters are not returned to the factory for maintenance, and no backup is carried out on the equipment of the Internet of things.

The method in the prior art has the natural defect that the FSG partition cannot be used again, and when the modestm 1 partition is abnormal in the use process of the Internet of things equipment, the modestm 1 partition cannot be restored to a factory state.

The original factory-leaving recovery operation of the internet-of-things equipment is only to operate a userdata partition, namely a partition for storing user data. When the userdata partition has a problem, the partition can be erased to restore the device to the factory state. This restore to factory state mechanism is only a partial restore. Only the userdata partition is recovered, not all partitions of the internet of things equipment, and the modestm 1 partition storing the parameters of the internet of things equipment 5G is abnormal, so that the method cannot be recovered.

Detailed Description

According to the method for saving and recovering the 5G parameters of the Internet of things equipment, disclosed by the invention, as shown in FIG. 3, firstly, software downloading and soft system installation are carried out on an empty chip, and when a modestm 1 partition is empty, a working mechanism of a high-pass platform can copy all NV parameter initialization values stored in an FSG partition to a modestm 1 partition.

Then, various factory settings and parameter writes are performed on the modestm 1 partition, for example, sequentially: the method comprises the following operations of single-board number writing, calibration comprehensive test parameter writing, single-board current parameter writing, single-board function writing, complete machine current writing, coupling test parameter writing, complete machine function writing, IMEI writing and the like.

And finally copying the modestm 1 partition after the operation to an FSG partition, and finishing the storage work of the parameters of the Internet of things equipment 5G.

The partition fsg is not operated in the normal use process of the internet of things equipment, and the partition fsg parameters are always in the initial state when the equipment leaves a factory.

When the Internet of things equipment surfs the internet and registers a 5G network, the parameters of the modestm 1 partition are read as required, and the running state can be written into the modestm 1 partition of the equipment, so that data interaction is carried out with the modestm 1 partition continuously in the running process.

Frequent data interaction naturally greatly improves the error probability of the 5G parameter. When the read-write modestm 1 partition is abnormal, the read-write abnormality affects normal operation of the device registration network and the modem, and at this time, the modestm 1 partition needs to be restored to a factory state. In the scheme of the invention, the problem can be solved only by rebooting the abnormal Internet of things equipment for two times by a user, wherein the partition of Modemst1 is cleared for the first time, and the partition of ResetModemst1 is completely cleared for the second time.

As shown in fig. 4, after each boot, the internet of things device checks the read-write function of the modestm 1 partition, and at this time, there are three possibilities, namely, null, normal, and abnormal.

1) When the Modmst 1 partition is abnormal in reading and writing, emptying the Modmst 1 partition;

2) when the Modemst1 partition is empty, copying the FSG partition to the Modemst1 partition for recovery;

3) and when the Modemmt 1 partition reads and writes normally, finishing the subsequent normal starting process.

Because the invention designs a specific step before factory production, all data of the Modemst1 partition is copied to the FSG partition for saving after the 5G parameter and the IMEI are written into the Modemst1 partition. Therefore, the operation of restoring the factory settings can be completely completed by the user without returning to the factory for maintenance. Certainly, restarting the internet of things equipment can be manually completed by manpower or automatically completed by restarting the system.

The Internet of things equipment is subjected to the 5G parameter storage operation and then is subjected to post-factory procedures. When the Modemst1 partition is abnormal in reading and writing, the recovery method is used for resetting the Modemst1 partition.

Various other modifications and changes may be made by those skilled in the art based on the above teachings and concepts, and all such modifications and changes are intended to fall within the scope of the appended claims.
