When a certain site initiates a cross-regional service, other related regions are judged through logic on an interface layer, distributed to each regional site through a shared bus, and a site logic lock is set; and for the condition of parallel processing of each area, after a certain area is processed, releasing the corresponding area logic lock, acquiring information corresponding to the area logic lock, only distributing the part of information to each associated area, and finishing data warehousing updating through interface service. By the method, the cross access efficiency of the distributed sites is improved, and the synchronization, consistency and accuracy of the service data are ensured; and meanwhile, a shared bus is introduced, so that cross data synchronization among all regional sites is reduced, the subsequent extension site deployment is facilitated, and when new regional sites need to be deployed, interaction with all other sites can be realized only by butting with the shared bus.
The data synchronization process of the present invention meets the data synchronization requirement of the original distributed sites, and after a shared bus is added in the middle of the distributed sites, the specific implementation process is as shown in fig. 4, and comprises the following steps:

And step 207, correspondingly distributing the packaged associated service data to each target area site through the shared bus.
And step 208, each target area station receives the shared bus notification, acquires the encapsulation entity, and updates the local area station related to the storage of the associated service data.
And step 211, after the source area station completes the logic lock of the associated part of the target area station, notifying the target area station through the shared bus.
And step 212, the target area site reversely acquires information related to the state change of the area site, encapsulates the service object, triggers the shared bus, reversely updates the source area site, and enters step 213 to release the area logic lock of the source area site after finishing the warehousing and updating of the data.
And step 213, releasing the regional logic lock by the source region site, returning the information recording object of the associated part from the locked state (namely, for update normal state) to a normal state, triggering a logic lock release completion message to the shared bus, and after receiving the message by the shared bus, putting the message into a data cache pool as the basis of the next synchronization process to complete the reverse data synchronization process of the distributed site.
The above steps 203 to 213 complete the whole distributed site data synchronization process, and support the whole process of distributed site data synchronization to multiple target area sites.
As described in the above steps, in the distributed site data synchronization process, the interaction between the source site and the target site is realized through the shared bus, so that the cross access between the source site and multiple target sites is reduced, and the real-time synchronization of data can be realized only by the source site interacting with the shared bus back and forth for 2 times; meanwhile, the regional sites use a logic locking technology to logically lock the associated information of the corresponding regional sites according to the state change condition of the regional sites, so that the data are in a temporary static state during interaction, and the data cross coverage during cross access is avoided.

2) query service order landing relates to regional area, such as relating to American BSS, European BSS, middle east non-BSS;
3) judging the related area affected by the operation of the service personnel, such as relating to American BSS and European BSS;
4. acquiring an American BSS service order state and an European BSS service order state through a shared bus;
1) if the state of the American BSS service order is not changed, setting an area logic lock for the American BSS service order, locking the associated service information of the American BSS service order and ensuring that the data is temporarily static;
2) the source area site sub-satellite BSS acquires package related American BSS order associated service information according to the bottom layer configuration service data object;
3) distributing the data object to an American BSS through a shared bus, receiving push information of the shared bus by the American BSS, and updating and warehousing the push information;
4) the American BSS releases the local area logic lock, returns to a normal state and completes data synchronization of the distributed stations;
