摘要:
随着3G UMTS网络架构的不断完善,用户对于系统吞吐量性能有着更高的要求。在系统中按需规划异构网络(HetNet),能够有效提升系统容量。对于HetNet的性能研究,需要利用仿真平台来模拟宏基站与微基站间的分布,通过在HetNet网络中布撒适量的用户Ue来完成仿真,进而得到对于HetNet系统性能的影响因素,对于网络规划提供仿真依据。HetNet网络的平台搭建主要涉及的是微基站(Pico)的布撒方法,及相应的Ue布撒方式。通过制定合适的仿真用例来考量HetNet系统性能的关联因子。得到HetNet网络提升热点区域吞吐量性能的基本规律。

Abstract:
With the improvement of 3G UMTS system infrastructure , mobile users have a higher requuirement in the system throughput. Building heterogeneous network (HetNet) on the planning in the system, can effectively enhance the system capacity.For the research of HetNet performance , we need to use the simulation platform to simulate the dropping scheme of macro and micro base stations,and distribute a amount of user equipments in HetNet to complete the simulation, then analysis the affecting factors of the HetNet performance. Providing the performance data for network planning program.There mainly relate to the scheme of dropping Pico base station and Ue distributing ways in the building of HetNet platform . We will focus on the related affecting factors of the HetNet system performance by drawing up appropriate simulation useing cases. Then we can conclude the basic law that HetNet will enhance the throughput of hotspot in the network.
