Problems solved by technology

It should be noted that the shadow fading of ground objects in the simulation has a different physical meaning from the shadow fading in the link budget. The former is the fluctuation relative to the median path loss on a certain ground object, while the latter is the fluctuation relative to the median path loss , there is no concept of feature classification

Description

technical field [0001] The invention relates to a simulation method in a wireless network, in particular to a network simulation method in a mobile communication system. Background technique [0002] Wireless network planning is instructive for operators' network construction. Good planning can successfully achieve a good balance among network coverage, capacity, quality and network construction cost, assisting operators to adopt the best implementation plan in each stage of network construction, upgrade and expansion, and realize the maximization of their network construction benefits . Network emulation is an important part of the network planning process. Through simulation, we can obtain some important performance parameters of the planned network, such as pilot coverage, best cell, system load, handover area, etc., which have important guidance and reference for actual networking. [0003] In the process of network planning of code division multiple access cellular m...
