基于业务特征的TDD-LTE端到端QoS参数研究

Study on end-to-end QoS parameters of TDD-LTE about the services of mobile internet

针对移动互联网快速发展对无线接入网的高带宽和业务质量需求,首先进行了常用的移动互联网业务研究分析;其次,依据业务特性、3GPP网络协议规范和本地已部署的TDD-LTE网络结构,提出了端到端QoS设置模型;最后,在商用网络上进行QoS参数部署验证。研究结果表明:在典型高速率业务环境下,TDD-LTE单小区峰值调度用户数增加253.92%;在现网混合业务拥塞环境下,TDD-LTE单小区峰值调度用户数增加81.80%。研究结果具备良好的行业应用性和推广性。

Aiming at the high bandwidth and service quality demand of wireless access network because of rapid development of mobile internet, the common mobile internet services were analyzed. According to the service characteristic, the 3GPP network protocol specification and the local TDD-LTE network structure which had been deployed, an end-to-end QoS setup model was proposed and QoS parameter deployment verification was performed on a commercial network. The experimental results show that in the resource-consuming scene, the peak user amount of single TDD-LTE cell are increasing by 253.92%; in the real bandwidth-congesting scene, the peak user amount are increasing by 81.80%. The results of the study have good application and popularization.
