Referring to Fig. 2, in one embodiment, a kind of data reconstruction method is provided, with the data reconstruction method application
It is illustrated in base station, includes the following steps S12 to S16:
S12, log-on data managing process；Wherein, data management process is for interaction data between each process of transfer
Process.
It is appreciated that in the system operation of base station, can be started by processor an independent data management into
Journey directly or indirectly interacts between the data management process and each process, as the hinge process of each process, in
Turn the interaction data between each process.
S14 passes through the corresponding target data of data management process backup target process；Target process is in each process
Any process.
Wherein, target data be transmission interaction data in, can be used for the data of recovering process state or transmission, such as
State class supplemental characteristic, files classes data or relation table class data.Interact with itself one of data management process pair is more
A target process interacts data relay simultaneously, can back up to the target data in interaction data.
Specifically, base station in the process of running can by data management process, to the interaction data of target process into
Row transfer and backup target data provide the unified management to each process transmission data.In other words, each target process
The interaction data of transmission is being forwarded corresponding receiving side process by data management process.Data management process is in
It, can in real time or the target data in schedule backup interaction data, in case when process exception, to do data extensive when turning interaction data
It is multiple to use.
S14, according to target data, passes through data management if data management process detection exception occurs to target process
Process carries out data recovery to target process.Wherein, it can be guidance extremely and cause transmission interaction data abnormal interrupt or error
The situations such as recovery, corrupted data or loss after various unusual conditions, such as process self-healing, network interruption.Data recovery can be
State before restoring the interaction data to abnormal moment of target process transmission, the state parameter for being also possible to restore target process arrive
State before the abnormal moment can also be that other can enable target process normal transmission interaction data and holding interaction again
The complete recovery process of data.
Specifically, in inside of base station, can by data management process transfer target process to receive target process different
Normal report or active detecting transmitted to target process data occur it is abnormal (such as in the interaction data of target process transmission
Disconnected, loss error) when, according to the target data of backup, data recovery is carried out to there is abnormal target process, such as will be corresponding
Target data import, or import target data simultaneously, it is synchronous by the interaction data in other processes of target data association
The target process that recovery is transmitted after exception is updated, so that the data transmission state of target process was restored to before the abnormal moment just
Normal state.
In above-mentioned data reconstruction method, by establishing independent data management process, for interaction number between each process
According to transfer, target data in backup interaction data.When data management process detection to target process is abnormal, data
Managing process can use the target data of backup to carry out data recovery to the target process that is abnormal, with restore target into

Fig. 3 and Fig. 4 are please referred to, in one embodiment, above-mentioned data reconstruction method further includes step S13a and S13b:
S13a passes through target process timed backup database file.
It is appreciated that for the data transmitting scene of database in base station, target process (such as database service processes),
In the data procedures for handling database, in addition to completing the load of normal database file, parameter configuration files are imported or export
It, can periodically Backup Data library file outside the operations such as database.The database file of backup is possibly stored to non-volatile deposit
It is spare on reservoir, such as the FLASH memory in base station.For example, target process can periodically detect whether data file goes out
It is now abnormal, such as database file is damaged or other abnormal conditions.If to detection end cycle when, database file is not
There are abnormal conditions, then Backup Data library file, so that exception, such as database file damage, database occurs in target process
Occur the abnormal conditions such as deadlock or self-healing when, data management process can call the database file of backup to target process into
Row data are restored.Wherein Fig. 4 is optional a kind of abnormal restoring flow diagram in the data transmitting scene of database.
S13b, it is standby if the interim table of the corresponding database of database file and/or database permanent relationship table change
The interim table in part changed data library and/or database permanent relationship table.
It is appreciated that the database that database saves can occur for target process interim in transmitting above-mentioned data procedures
When table changes or wide area information server permanent relationship table changes, the database after immediate backup changes is interim
Table or database permanent relationship table.Target process can also change in the interim table of database and database permanent relationship table
When change, the interim table of immediate backup database and database permanent relationship table.For example, target process passes through the interim table of registration database
Call back function, realization change in the interim table of database, then the interim table of database after variation is backuped to accordingly immediately
In the configuration file of volatile ram.Target process passes through the call back function of registration database permanent relationship table, realizes in data
Library permanent relationship table changes, then immediately backups to the database permanent relationship table after variation in corresponding configuration file,
Such as the data base configuration file on FLASH memory.
In this way, S13a and S13b through the above steps, data management process can in target process interactive process,
It backs up in realtime the interim table of database therein, it is so as to when detecting that target process occurs abnormal, the database of backup is interim
Table is supplied to target process, after the Backup Data library file and data library permanent relationship table that import target process, is backed up
The interim table of database complete data and restore.

Database file in process, and the database file of backup is synchronized to target process；
The interim table of the database of backup and database permanent relationship table are synchronized to target by data management process by S164
Process.
Specifically, after the database file that data base administration process detection to target process transmits is by abnormal damage, number
According to managing process by database file original in delete target process, and by the database file of backup be loaded into target into
Journey is completed the synchronous of database file and is restored.However, when the database file in target process is compared to abnormal occur at this time
It carves, can have partial data and not update last state, and the interim table of database and database permanent relationship table are also in loss
State.Therefore, data management process can continue to import the interim table of database of backup to target process and database permanently closes
It is table, normal condition namely last state before the database file of target process to be restored to the abnormal generation moment.This
Afterwards, with target process interaction other processes can by with target process interact complete data it is synchronous, recovery normally
Data transmission and processing.When other processes for interacting with target process occur abnormal, such as self-healing, then its after abnormal restoring
When his process is linked into target process, the data after recovery can be synchronized to other processes above-mentioned by target process, so that should
Other processes are promptly restored to abnormal preceding normal condition.
S162 and S164 through the above steps, can be when target process be abnormal situation, by data management process
Corresponding Backup Data is synchronized, rapidly and reliably realizes that the data of the target process after exception are restored, can additionally pass through
Other processes of target process Fast synchronization further increase the efficiency of data recovery and the stability of base station system, are conducive to reduce
Maintenance cost.
Referring to Fig. 7, in one embodiment, above-mentioned data reconstruction method can also include step S18:
S18 notifies target process Backup Data library file by data management process.

Backup Data library file is in case use.Data management process simultaneously, can lead to target process load Backup Data library file
Know that target process carries out Backup of database files again, backs up spare on the database file to nonvolatile memory.In this way,
S18 through the above steps can ensure to improve target process abnormal restoring there are available Backup Data library file at any time
Reliability, and then improve the system stability of base station.
Referring to Fig. 8, in one embodiment, target data includes state parameter data.It is specific to go back about step S16
May include following process:
If data management process detection exception occurs to target process, pass through data management process for state parameter data
Synchronized update is to target process.Wherein, state parameter data are the state class parameter after target process completion function switch, such as
In LTE base station, state, the connection status of S1 or X2 link etc. that state, the network configuration that each chip configuration is completed are completed are loaded
State parameter data.
Specifically, target process after the function switch for completing certain stage, corresponding state parameter data can be synchronized
Data management process is sent to be backed up.When target process occurs abnormal, data management process then can be by the shape of backup
State supplemental characteristic synchronized update is to there is abnormal target process, so that target process is fast according to the state parameter data received
Normal condition before quick-recovery to abnormal moment.It is appreciated that can similarly understand for other target process.
The detailed process of S16 through the above steps can pass through data management process when target process occurs abnormal

May include following process:
If data management process detection occur to target process it is abnormal, by data management process according to having received recently
File data packet, notice target process restores to send remaining file data packet；By data management process, it is surplus to restore forwarding
Remaining file data packet.
Wherein, the profile data packet that file data packet transmits between different processes, for example, log, performance or its
His configuration file.Specifically, data management process is in transfer file data in a base station in the transmitting scene of non-database data
Bao Shi can recorde the file data packet for receiving target process such as process A, and the file data packet forwarded, such as forward
To the file data packet of process B.When target process occurs abnormal, such as unstable networks or other reasons lead to target process
When transmitting file data packet abnormal interrupt, data management process then can be when transmission conditions be restored, such as setting time Intranet
When network restores, nearest received file data packet is notified that, to target process, target process then can be from the number of files of interruption
According to package location, continue to send remaining file data packet being given to data management process.In turn, data management process can be from nearest
The file data packet forwarded not successfully continues to forward remaining file data packet, is such as forwarded to process B.
In this way, the detailed process of S16 through the above steps, can occur in target process abnormal, lead to file data packet
When failing to complete transmission, synchronizes the transmission state of target process rapidly by data management process, restore normal file data

If data management process detection exception occurs to target process, pass through data management process for state parameter data
With performance data synchronized update to target process.Wherein, process critical function is influenced whether when performance data is loss of data
Using or cause other data transmission with processing problem data.It is appreciated that the memory of data management process may store
Data volume it is relatively limited for nonvolatile memory, therefore, data management process can only save data recovery
Required target data, performance data, file data packet and state parameter data as escribed above etc., the file of remaining transfer is only
It forwards.When target process occurs abnormal, such as there is performance data damage in target process, causes certain functions unavailable
When, data management process can be by the performance data of backup together with state parameter data synchronization updating to target process, so that mesh
Mark process is restored according to the performance data and state parameter data that receive.
The detailed process of S16 through the above steps can occur important performance data damage in target process or lose
When mistake etc. is abnormal, backup and synchronized update by data management process can quickly and reliably be completed to restore, and improve target
The data recovering efficiency and system stability of process.
In one embodiment, above-mentioned data reconstruction method further includes following steps:
