Study On NSN N+X HLR Redundancy Backup System

With the development of communication market, the market competitionis increasingly fierce, the user’s demand grow with each passing day. Forimproving network quality customer perception, meet many operators,starting from the competition of communication market development andmeet the needs of the user perspective, how to solve the problems of Shanghaimobile Nokia HLR N+1disaster recovery network has become the imminenttask.Firstly, it starts with the NSN HLR hardware structure which ishighlighting the NSN HLR equipment components, interfaces and variousmodes of disaster avoiding systems, which is presenting that NSN old HLR N+1backup network is not good enough at real-time maintenance and has badperformance at user experience, then based on the research of the evolutionfrom NSN N+1to N+X system, focusing on the result of comparison on allthe aspects of old and new recovery system. At the end, used lots of theevidence from live network experience to prove that the new NSN N+Xsystem has the stronger real-time usage, and fixed the problems/shortageswhich were existing in old NSN N+1system. The new NSN N+X system can provide the comprehensive security on all kinds of services for all the telecomclients.In this research, you can also find the useful discussion regarding thefurther performance evaluation, maintenance specifications on NSN newN+X redundancy mechanism which can be also used as the reference andbenchmark for the maintenance and popularization for NSN N+X networkredundancy system.
