In existing system upgrading scheme, the storage order of each partition information is unfixed in partition table, for example, going out
Under factory's facilities, the user data partition information in primary partition table is located at the rearmost position of partition table, when once being risen
After grade, user data partition information may be stored in the initial position of partition table.Since user data partition information is dividing
Position in area's table changes, and user data partition information may also can be modified, and will lead to the number in user data subregion
According to loss.In addition, if the storage address of user data subregion, which changes, may also lead to loss of data, specifically, if with
The initial address of user data subregion changes, and the content in user data subregion is caused to lack or wipe completely.Such as to avoid
Because partition table upgrading leads to user data loss, therefore, to assure that position of the user data partition information in partition table is not modified,
Ensure that the initial address of user data subregion is constant simultaneously.
Fig. 1 is the flow diagram of method for upgrading system provided in an embodiment of the present invention, and this method mainly includes following step
It is rapid:
101: original subscriber's data partition information for being stored in former partition table is obtained, in original subscriber's data partition information
Former initial address and former end address including user data subregion, original subscriber's data partition information are located at the former subregion
The initial position of table.
In former partition table, while many data partition informations are stored with, for example, user data subregion (userdata) is believed
Breath, kernel partition information, system partition information etc..It may include former starting point in original subscriber's data partition information
Location (for example, original subscriber's data subregion starting head number, sector number etc.), former end address are (for example, original subscriber's data subregion terminates
Head number, sector number etc.) and file system flag bit etc..Original subscriber's data partition information mentioned here is located at former aging schedule
Initial position, it can be understood as original subscriber's data partition information will be leaned on than position of other partition informations in partition table
Before, in other words, user data partition information is located at first position in all partition informations.When other partition informations carry out more
When changing or when storage order of other partition informations in partition table is modified, not for original subscriber's data partition information
It is modified, original subscriber's data partition information is stored in the initial position in former partition table.
102: acquisition is stored in new partition table new user data partition information, wraps in the new user data partition information
The new initial address and new end address, the new user data partition information for including the user data subregion are located at described new point
The initial position of area's table.
In practical applications, new partition table mentioned here is the system upgrade obtained by over the air (OTA)
Parsing obtains in data packet.In the upgrading of subsequent progress operating system and partition table, therefore, to assure that new user data point
Area's information is located at the initial position of new partition table.New user data partition information mentioned here is located at the start bit of new aging schedule
It sets, it can be understood as new user data partition information will be forward than position of other partition informations in partition table, in other words,
User data partition information is located at first position in all partition informations.To partition information in former partition table and new partition table
Storage location is as shown in Figure 2.
It should be noted that there is no the limitations of strict sequence for step 101 and step 102, and in other words, Ke Yixian
It executes step 101 and executes step 102 again, step 102 can also be first carried out and execute step 101 again.
103: if the original initial address is identical as the new initial address, and the former end address and the new knot
Beam address is different, then carries out system upgrade according to the new partition table.
After obtaining former partition table and new partition table, initial address and end address are compared.Specifically, first
Compare former initial address and new initial address, if former initial address is identical as new initial address, it is possible to further more former
End address and new end address.
If former initial address is identical as new initial address, also, former end address and new end address are also identical, then are dividing
User data partition information in area's table is not needed there is no any variation in the data and partition table in user data subregion
User data partition information upgraded.For example, generating system upgrade if user data subregion does not need to be upgraded
When data packet, part upgrading can be carried out, user data partition data can not be included in system data upgrade package, is used
User data partition information etc.；So as to simplify updating operation, upgrading efficiency is promoted.
If former initial address is identical as new initial address, former end address is different from new end address, then it represents that partition table
Changed, the size in corresponding partitioned storage space is also changed.It then needs to partition table and operating system simultaneously
Upgraded.
In one or more embodiment of the invention, the acquisition is stored in new partition table new user data subregion
Information can specifically include: being based on aerial downloading mode, obtains system upgrade data packet；Parse the system upgrade data packet

It later, can also include: that the corresponding user of the new partition table is determined based on the new initial address and new end address
The default memory space of data subregion；Compare in the corresponding user data subregion of the former partition table data occupied space with
The size of the default memory space；If the data occupied space is greater than the default memory space, terminate according to
The system upgrade of new partition table.
For example, determining the default of the corresponding user data subregion of new partition table according to new initial address and new end address
Memory space is the space 1G, default memory space mentioned here, it can be understood as set in manufacturing system upgrading data packet
Fixed memory space.The data occupied space stored in the corresponding user data subregion of former partition table is the space 1.2G, it is known that, number
The size of default memory space 1G is significantly greater than according to occupied space 1.2G, if according to the knot of new partition table change user data subregion
Beam address will lead to the loss of user data, and therefore, it is necessary to terminate the upgrading according to new partition table to operating system.Due to pre-
If the size of memory space can no longer meet the existing user data of storage, therefore, can without to former initial address and
The comparison of new initial address.
In one or more embodiment of the invention, if can also include: that the data occupied space is less than or waits
In the default memory space, then whether the former initial address and the new initial address are identical.
For example, presetting memory space is 1.2G, then data occupied space is significantly less than default if data occupied space is 1G
Memory space can continue former initial address compared between new initial address.So as to further determine whether
The upgrading of partition table and system can be carried out based on new partition table.
In one or more embodiment of the invention, it is more described original initial address and the new initial address whether
It is identical, if can also include: that the former initial address is different from the new initial address, terminate according to the new partition table
System upgrade.
If the former initial address in former partition table is different from the new initial address in new partition table, then it represents that partition table and right
The actual storage address for the user data subregion answered all is changed, if continuing the behaviour for executing system upgrade according to new partition table
Make, it will the user data in user data subregion is caused to be deleted.Therefore, if it was found that former initial address and new starting point
Location is different, then no longer needs to the former end address of comparison and new end address, can terminate the operation according to new partition table to system upgrade.
In one or more embodiment of the invention, if can also include: the former initial address and described new
Beginning address is identical, and the former end address is different with the new end address, saves the described of the user data subregion
Former initial address is constant, and the former end address for updating the user data subregion is the new end address.
In practical applications, if by after comparison, it was found that, former initial address is identical as new initial address, former end address with
New end address is different, in order to avoid the data in user data subregion from being wiped free of, saves the current of user data subregion
In the case that initial address (the current initial address and former initial address and new initial address are all identical) is constant, by user data
The end address of subregion is updated to new end address.For example, can be terminated using Resize2fs instruction adjustment user data subregion
Address is the end address in new partition table.
In one or more embodiment of the invention, the new partition table in the system upgrade data packet is parsed
It later, can also include: the partition information for obtaining other data subregions in the new partition table；Believed according to other described subregions
Breath updates initial address and the end address of other data subregions.
In practical applications, if desired operating system is upgraded, it may be necessary to while to multiple data subregions and dividing
Corresponding partition information is upgraded in area's table.Therefore, it is also desirable to obtain other data subregions and corresponding partition information.Here
Other described data subregions can be understood as in system, the data subregion other than user data subregion.If other data
Partition information changes, then needs to carry out the updating operation of each data subregion according further to other data partition informations.
It is described that system upgrade is carried out according to the new partition table in one or more embodiment of the invention, specifically
It may include: the load new partition table；The upgrading partition data in the system upgrade data packet that parsing is obtained, write-in
To other updated described data subregions.
