Research On SDR Network Transformation Strategy Of China Unicom Qinhuangdao Branch

Although has now been into the 4 g era,however,many users are still using 2 g mobi le networks,in the foreseeable future time operator can't completely shut down 2 g mobile networks.As the 2 g equipment ageing,use fixed number of year,gradually achieve the d esign failure rate,power consumption rising,operation maintenance cost increases.Operat ors,meanwhile,it is impossible to put new cost to purchase 2 g device to replace the origi nal old equipment,so without any increase in hardware equipment investment,on the basi s of using the SDR technology of 4 g + 2 g network model,replacing the original old equi pment,2 g is operators achieve saving energy and reducing consumption,to reduce the op erating costs,while increasing the most quick and efficient way to network coverage quali ty goal.Unicom qinhuangdao branch as the province's first introduced the SDR 4 + 2 hybr id networking vendors equipment synchronization network cities,facing the G/L net const ruction,G band frequency multiple projects in parallel,cause local network structure com plexity increases,more new and used equipment replacement and so on a series of practica l network problems.First,the significance of this paper is to analyze and solve step by step the SDR 4 + 2a series of practical problems existing in the network optimization work,ensure that let m ore unicom mobile network users enjoy the best quality service,enjoy the high quality 4 g + 2 g network experience.Secondly,this paper systematically expounds the SDR 4 + 2 hybrid networking back ground reasons of network construction and network structure characteristics,and then the advantages and disadvantages of existing in the network and related key technologies wer e analyzed carefully,and then combined with practical engineering experience system in t his paper,the principle of 2 g / 4 g interoperability.Again,this article induces and summarizes unicom qin branch for the SDR 4 + 2 net work retrofit scheme strategy analysis,and through a lot of skill front road test data analys is and parameter adjustment background,theory combined with the actual proposed a set o f feasible SDR 4 + 2 network transformation strategy and implementation plan.Finally,this article through to the unicom qin points the SDR 4 + 2 network transfor mation strategy analysis,from the perspective of practice,aiming at complex pattern of co existence of unicom network more for dominated by LTE network parameters of planning and puts forward some practical point of view,and China unicom to LTE network constru ction and optimization of the current help.
