Application Research On Traffic Balancing Technology In GSM And TD-SCDMA Networks In Harbin

As customers demand more diversified and faster mobile communications services,the traditional call communication system can no longer meet the requirements of users,and the market position of 3G networks becomes even more important.As a result,2 / 3G networks will coexist and assist each other for a period of time,which puts higher demands on the network support and optimization.It requires that 2 / 3G networks be more synergistic and meet the needs of users.In this paper,Harbin as the experimental area,from the perspective of coverage and capacity balance of GSM and TD network traffic balance technology.First of all,we should understand the characteristics of GSM and TD network,including the network structure,technical characteristics and the interoperability flow between GSM and TD networks.We will summarize the key technologies and parameters that affect the balance of GSM and TD network services in coverage,Coverage adjustment and soft coverage adjustment of two measures to optimize the coverage of GSM and TD network balance.The hard coverage mainly adjusts the unreasonable attitude of the GSM and TD network antennas to achieve more reasonable coverage of the two networks,thereby ensuring that the TD network has enough capacity to access users and share more services.Soft coverage is mainly through reasonable parameter adjustment,to ensure that the key performance indicators of the network does not decline at the same time,a reasonable business presence in the current network diversion.In the end,the coverage of GSM and TD network is optimized to achieve the best effect under the double means of hard coverage adjustment and soft coverage adjustment so that the TD network can maximize the traffic of the offload traffic.In terms of capacity,after the coverage equalization operation,the traffic volume of GSM and TD networks changes greatly,and the capacity requirements of different cells of the two networks change.In this case,the cell capacity needs to be adjusted in time to ensure that the network can bear the traffic load Potential business volume to avoid or reduce call loss.Therefore,this paper studies and studies the equipment and related licenses of GSM and TD network equipment vendors currently used in Harbin to master the number of carriers supported by different versions of different hardware models,and finally formulates the relevant hardware or license adjustment The adjustment of the threshold and adjustment process will guide the subsequent capacity adjustment of GSM and TD networks.The adjustment methods and technical process obtained through the previous research are finally applied to the overall network in Harbin and verified.
