Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] figure 2 The flow chart of the data synchronization method provided by the embodiment of the present invention, such as figure 2 As shown, the specific steps are as follows:

[0038] Step 200: Preset data synchronization period.

[0039] The data synchronization cycle can be adjusted according to the network adjustment. When the network adjustment is frequent, the data synchronization period can be set smaller; when the network adjustment is infrequent, the data synchronization period can be increased.

[0040] Step 201: In each data synchronization cycle, the DNS data processing module sends a download request to the File Transfer Protocol (FTP, File Transfer Protocol) server, which carries the DNS device address, including the correspondence between the community number and the dedicated IP address of the GN port The st...

Abstract

The invention discloses a method and an apparatus of data synchronization. The method includes reading the correspondence between all of the cell numbers and the private IP (Internet Protocol) address of the Gn interface from the DNS (Domain Name System) device, reading the correspondence between all of the cell numbers and the private IP address of the Gn interface from each of the SGSN (Service GPRS Supporting Node) respectively, and for any cell number, updating the private IP address of the Gn interface on the DNS device with the private IP address of the Gn interface read from the SGSN, if the private IP address of the Gn interface corresponding to the cell number read from the DNS device is different from that from the SGSN. According to the method and apparatus of data synchronization, the data synchronization between the DNS device and the SGSN is achieved.

Description

technical field [0001] The invention relates to the technical field of mobility management, in particular to a data synchronization method and device. Background technique [0002] Today, with the rapid development of mobile communications, the use of General Packet Radio Service (GPRS) has shown explosive growth. How to enable users to use continuous and high-quality networks is the main problem to be faced now. [0003] A very important process in GPRS network mobility management is handover, which can ensure that users experience continuous and uninterrupted data domain services. [0004] In the current network, when a mobile terminal (MS, Mobile Station) enters another SGSN from one GPRS Serving GPRS Support Node (SGSN, Serving GPRS Support Node), handover between SGSNs will occur. figure 1 The message flow chart of the existing MS switching between SGSNs is given, such as figure 1 As shown in the figure, assume that the MS performs data domain service experience in Ce...
