Embodiment 1

[0030] Please refer to the attached figure 1 , which is a flow chart of a method for data synchronization between an active HLR and a backup HLR disclosed in an embodiment of the present invention, the method may include:

[0031] Step S101: when the first predetermined time arrives, obtain the main HLR user data in the main HLR; when the second predetermined time arrives, obtain the backup HLR user data in the backup HLR;

[0032] There is a backup mechanism between the main HLR and the backup HLR in the prior art, and the backup mechanism automatically backs up user data every day and generates a daily data backup file. The user data of the main HLR can be stored in the main HLR. Daily data backup files, the backup HLR user data can be the daily data backup files in the backup HLR, specifically, the main HLR and backup HLR daily backup data files can be collected by the standard file transfer protocol FTP mode, the present invention The acquisition of the main HLR user data...

Embodiment 2

[0059] see figure 2 , which is a schematic structural diagram of a device for synchronizing data between a primary home location register HLR and a backup home location register HLR disclosed in an embodiment of the present invention, the device may include: a primary HLR user data acquisition module 201, a backup HLR user data acquisition module 202, standard data conversion module 203, acquisition difference user data module 204, instruction conversion module 205, sending module 206, wherein:

[0060] The main HLR user data acquisition module 201 is used to obtain the main HLR user data in the main HLR when the first predetermined time arrives;

[0061] In the case where at least two main HLRs correspond to one backup HLR, the main HLR user data acquisition module 201 is specifically: when the first predetermined time arrives, serially collect the main user data in each main HLR HLR user data.

[0062] In the case where at least two main HLRs correspond to at least two ba...

Embodiment 3

[0078] see image 3 , which is a schematic structural diagram of a data synchronization system for a primary home location register HLR and a backup home location register HLR disclosed in an embodiment of the present invention, the system may include: a primary HLR user data receiving port 301, a backup HLR user data receiving port 302 , a first flip-flop 303, a second flip-flop 304, a processor 305 and a comparator 306, wherein:

[0079] After the first predetermined time arrives, the first trigger 303 triggers the main HLR user data receiving port 301 to acquire the main HLR user data; after the second predetermined time arrives, the second trigger The device 304 triggers the backup HLR user data receiving port 302 to obtain the backup HLR user data;

[0080] The processor 305 converts the obtained main HLR user data and the backup HLR user data into main HLR user standard data and backup HLR user standard data according to a first predetermined rule; the comparator 306 comp...

Abstract

The embodiment of the invention discloses a method, a device and a system for data synchronism. The method comprises the following steps of: acquiring master home location register (HLR) user data in a master HLR and acquiring backup HLR user data in a backup HLR; converting obtained user data into master HLR user standard data and backup HLR user standard data according to a first preset rule; comparing the master HLR user standard data with the backup HLR user standard data to obtain difference user data; converting the difference user data into an operation instruction for modifying backup HLR difference user data in the backup HLR; and transmitting the operation instruction to the backup HLR for updating the backup HLR difference user data according to the operation instruction by the backup HLR. By the method, the device and the system provided by the embodiment of the invention, a signal fault point cannot be brought in.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a data synchronization method, device and system. Background technique [0002] In the communication network, HLR (Home Location Register, home location register) is at the highest layer of the network, storing information such as user phone number, user status, subscription status, subscription relationship, etc., which are crucial to the provision of mobile services . Once the HLR breaks down (such as unforeseen reasons such as man-made damage, earthquake, and lightning strike), it will directly cause millions or even tens of millions of users to be unable to communicate normally, so two HLRs are used as the main HLR and the backup HLR respectively. When the HLR is normal, the main HLR is used to store and provide user data, and if the main HLR fails, it will switch to the backup HLR, so the data synchronization between the main HLR and the backu...
