Engineering Reform Of Gr Interface Over IP

With the rapid development of mobile network, the amount of signaling generated by mobile network along with the growing number of users. While the entire mobile network evolution is toward packetized. As a business support network, the transmission bearing technology of SS7 network is constantly advancing with the times. Upgrade traditional SS7 signaling link transmission rate, deployment of IP signaling network, and the implementation of SIGTRAN technology make the SS7 transport bearers from TDM to IP.Gr port as a key interface to PS(packet switched) domain core network plays an important role of the signaling interaction between the SGSN and the HLR. Gr port IP-based signaling links can increase bandwidth and reduce the signaling network transmission costs, simplified protocol type, reducing network complexity level signaling network. Gr Interface uppermost taking the MAP protocol, MAP protocol is still an important agreement in the future of mobile communication, currently many mobile value-added services or mobile Interface query user information through the MAP signaling, business platform server-based IP interfaces, network using IP signaling transmission technology will reduce business development and mobile network integration costs.Although IP-based signaling has been proposed for a long time, but the major operators will now begin the concrete implementation of IP signaling network on the implementation of the transformation of some of the important core network elements.This article will take this Gr interface IP-based engineering of Jiangsu Mobile SGSN, from the SGSN point of view, in-depth explanation of how SIGTRAN technology in particular telecommunications NE, M3 UA and SCTP protocol specific principles. And engineering practice, comparison of the data from the specific IP signaling link and TDM link, analyze Gr interface of the benefits of IP and post need to pay attention and optimization.
