The following describes the embodiments of the present invention by using specific application scenarios as follows:

The application scenario of the present invention is specifically a FOTA upgrade solution. For the application scenario, the terminal uses the smart phone as an example, and the existing Android FOTA upgrade technology is used when the mobile phone is to be upgraded by FOTA. The FOTA differential package is downloaded and then copied to the cache partition of the mobile phone; the mobile phone automatically restarts to the recovery mode, and the FOTA differential packet of the cache partition is processed for FOTA upgrade.

The problem with the existing Android FOTA upgrade technology is that because the cache partition user is invisible, usually the cache partition is relatively small. When the operating system is upgraded, the FOTA differential packet size will definitely be larger than the cache partition. The size of the phone can not be upgraded by a large version of FOTA. If the upgrade package fails, the upgrade will fail. The problem that needs to be solved now is to correctly store the upgrade package to avoid the upgrade failure. It can be seen that it is very important to correctly parse the upgrade package from the storage area. It should be pointed out that the importance of parsing the upgrade package is also that When determining whether someone else is infringing, because of the external storage area such as userdata partition or SD card, both of which are visible partitions, you can read the partition information and FOTA in the built-in or external storage area of the other party's mobile phone. The size of the differential packet is determined by analyzing the updated log information to determine whether the other party's mobile phone has been infringed.

Corresponding to the above problem, the application scenario adopts the embodiment of the present invention. Even when the FOTA differential packet is relatively large, the mobile phone can still store correctly, correctly parse the FOTA differential packet, thereby avoiding the upgrade failure, and can also bring a series of help confirmation rights. effect.

Application scenario 1:

The user data partition of the mobile phone is a partition visible to the user. The partition is generally referred to as user space, and the remaining size indicates the size of the space that the user can use for photographing, downloading songs, and the like. The general mobile phone userdata partition space will be relatively large, it will be the cache partition 5-8 times the size, can be used as the target storage area. The FOTA upgrade steps are as follows:

Step 401: Download a FOTA differential packet to a user data partition by using a FOTA application.

Step 402: After the FOTA differential package is downloaded, the mobile phone automatically restarts into the recovery mode.

Step 403: Mount the userdatata partition in the recovery mode.

Step 404: In the recovery mode, after reading the FOTA differential packet in the userdata partition, perform a FOTA upgrade operation;

Step 405: After the FOTA upgrade operation is completed, delete the FOTA differential packet in the userdata partition in the recovery mode.

In step 406, the mobile phone automatically restarts.

Application scenario 2

The above application scenario only takes the userdata partition as an example, and an external SD card (or sdcard) can of course be used as a target storage area. If the user's userdata partition has insufficient space, if there is any space left by the external sdcard inserted by the user, download the FOTA differential packet to the sdcard. In the recovery mode, mount the sdcard partition and read the FOTA difference in the sdcard partition. Package for FOTA upgrade. As shown in Figure 5, this application scenario 2 includes both the userdata partition and the external SD, which can be used as the target storage area. The FOTA upgrade process is as follows:

Step 501, obtaining a differential packet size of the FOTA server by the FOTA application is A;

Step 502: Obtain a remaining space size of the mobile phone userdata as B;

Step 503, compare the size of A and B, if A < B, then perform step 504; if A > B, then perform step 505;

Step 504, the differential packet download is stored to the userdata partition; afterwards, the process proceeds to step 509;

Step 505: The remaining space size of the external sdcard is C.

Step 506, compare the size of A and C; if A < C, step 507; if A > C, then step 508;

Step 507: Download the differential package to the sdcard.

Step 508: prompt the user to delete unused data, or insert another sdcard with a larger remaining space than A;

Step 509: After downloading and storing the differential packet, the mobile phone restarts into the recovery mode.

Application scenario three:

The userdata partition and external SD card (or sdcard) of this application scenario 3 can be used as the target storage area. If the user's userdata partition has insufficient space, if there is any space left by the external sdcard inserted by the user, download the FOTA differential packet to the sdcard. In the recovery mode, mount the sdcard partition and read the FOTA difference in the sdcard partition. Package for FOTA upgrade. As shown in Figure 6, this application scenario includes both the userdata partition and the external SD, which can be used as the target storage area. The process in the recovery mode includes:

Step 601: loading the userdata partition in the recorey mode;

Step 602, determining whether there is a FOTA differential packet in the userdata partition, and if so, executing step 605; otherwise, executing step 603;

Step 603: There is no FOTA differential packet in the userdata partition, and the sdcard partition is loaded;

Step 604, determining whether the sdcard partition has a FOTA differential packet, and the sdcard partition has a FOTA differential packet, step 605;

Step 605: If there is a FOTA differential packet, pass the correct differential packet file path to perform FOTA upgrade processing;

Step 606: After the mobile phone FOTA is successfully upgraded, the FOTA differential packet corresponding to the FOTA upgrade is automatically deleted.

It should be pointed out here that there is also a specific application scenario, which is to split the large FOTA differential package into small FOTA differential packages, so that multiple upgrades can be achieved by using the Android native FOTA upgrade scheme. Users need to download and upgrade multiple times.

The beneficial effects that can be achieved by the embodiment of the present invention are as follows:

For the case where the upgrade package of the mobile phone firmware is relatively large, such as the case of using the FOTA software version upgrade for the larger FOTA differential package, the user's effective storage space can be utilized for the FOTA upgrade. Moreover, it is also compatible with Android's native FOTA upgrade solution, and can be superimposed with Android's native FOTA upgrade solution, which is better in use. Applying the embodiment of the present invention to the P821A20 mobile phone, the FOTA upgrade of the large version of the Firefox system has been implemented, and the Firefox V1.3 system is upgraded to the V2.0 system.
