Research On QoS Deployment Method For Transmission Network Under The TD-LTE Condition

TD-LTE network construction of China Mobile needs of the explosive growth of network bandwidth and network transmission performance,The QoS deployment of transmission network of 4G network will directly affect customer perception.For different ?sers,how to realize differential service,minimize the congestion rate of LTE transmission network,improve the transmission network bandwidth utilization rate,the key problem of transmission network deployment of QoS is high grade business without blocking when network congestion.The method of necessary routing of QoS deployment can reduce network congestion rate,improve c?stomer perception.This paper mainly studies the QoS deployment model of LTE transmission network based on necessaryrouting conditions for LTE transmission network,according to the network modeland the depiction of business,the mathematical model of algorithm has been given,describes the main design ideas of the necessary routing algorithm based on QoS deployment,has been designed the deployment of the method in accordance with the model,and has been tested on the network of communication in Liaoning of China Mobile,after deployment,the function of QoS has been verificated.First of all,in order to achieve the business of classification management end to end,find the methord between the Algorithm of the bandwidth and traffication of vario?s business,considering the link cost and load balancing,the paper designed deployment algorithm for transmission network of QoS based on necessaryrouting;and then finished overalldesign method of QoS deployment of LTE transmission network,clear the current network situation,All kinds of business deployment of QoS priority,and according to the application scenarios of different business,on the condition of TD-LTE,the specific business respectively the typical application scenarios,network protection method and the planning of QoS deployment has been given.And then,the paper selected local transmission network of Dalian of China Mobile as deployment of QoS,uses the methord of deployment for QoS of transmission network had been designed,the studies has been finished on the deployment for QoS of whole network and the functional test.Finally,through the test to draw the following concl?sions:based on the necessary routing of deployment method for QoS can be applied to the current network,can effectively control the network congestion.when congestion occurs inevitable,the LTE network had been finished the deployment for QoS,can ensure the business fo high level service without blocking.he deployment method for QoS of LTE transmission network under the condition of TD-LTE,is suitable for the application of a variety of business based on current network scenarios.
