The Research And Accomplishment Of HLR Redundancy Technology

As mobile core network gradually expand the scale, the number of mobile users growing。THE Traffic of Shanghai Mobile Company Ltd's core-network rapid growth. At the same time,the network security has put forward higher requirements of stability. HLR as a mobile core network of key equipment, although has redundancy system, but disaster response rate, economic disaster, reliability and so on can not meet the business development. For the majority of mobile users to provide more security and stability network services, it's important to improve Shanghai Mobile HLR redundancy system.This topic first introduced the background, on the development of mobile networks, and has proposed the establishment of an effective core redundancy network.Second, research the theory of disaster communications network and mobile communication technology system, analysis basic mentality and clue of the HLR redundancy from reliability theory and technical implementation, and found the technology application by comparing identified HLR N + X redundancy.Then, from the detailed analysis the key technology of several aspects of the HLR N + X redundancy,and propose Ericsson, Nokia HLR N + X redundancy programmes, to improve the Shanghai Mobile HLR redundancy system equipment.Finally, the subject of a summary and look HLR redundancy technology will further the development direction.
