摘要
为研究TD网络高负荷场景下对网络性能指标的影响,对比分析了在整体网络高负荷持续升高的场景下,对CS业务、普通PS业务、HSDPA业务和并发业务指标的影响,结果表明网络整体负荷大于60%以后,由于上行码资源受限,网络整体性能指标开始恶化,用户感知变差。针对网络高负荷问题主要通过拥塞控制解决,并提出了合理的优化措施,为降低网络高负荷提供了理论依据和指导。
In order to study the impacts on network performance under high load scenarios of TD networks, the impacts on the indicators of CS business, PS business, HSDPA business and concurrent business are analyzed under the increasing network load of overall networks. The results show that the overall performance of networks begins to deteriorate and the user perception becomes bad because of the constraints of the uplink resources when the overall network load is larger than 60%. The high load problems of networks are mainly solved by congestion control and reasonable optimization measures are put forward, which provides the theory foundation and instruction to decrease the network load.
