TD-LTE网络优化方案设计

学生：王 明 指导教师：倪 磊

内容摘要：TD-LTE无线网络优化有两个运行阶段：一是工程优化阶段，第二,运营阶段。本文的研究方向是工程优化阶段。工程优化阶段分为阶段的单站优化,优化集群,整个网络优化阶段。每个阶段的任务是不一样的,但我们的目标是一样的,两个阶段的目标都是相同的，两个阶段的目标是让用户得到最大价值,实现最佳组合的网络覆盖、容量和价值。用户通过无线网络优化方法提高产量和节约成本。为了达到要求的KPI指标，我们针对优化工作：覆盖优化，切换优化，干扰优化，RR优化做出分析。经过这些反复的优化流程以确保广大用户能正常使用LTE无线网路。本文将重点介绍上述工程优化三个阶段的优化流程和方法，以与介绍无线网络优化主要优化任务，还有优化过程中经常遇到的问题和解决方法。

Design Of Optimization in The TD-LTE Network

Abstract:

The TD-LTE wireless network optimization, there are two operation

stages: one is the engineering optimization phase, the second,

the operational

phase. In this paper, the research direction is engineering optimization

Phase.

Engineering optimization phase is divided into phases single

station

optimization, optimization of the cluster, the entire network optimization

phase.

Each stage task is different, but our goal is the same, two Goals are the same,

the two stages the goal is to let users get the most value, to achieve the best

combination of network coverage, capacity and value. Users via wireless

network

optimization method to Increase production and save cost. In order to satisfy

the the requirements of KPI, we optimized work: coverage optimization, the

switch

optimization, optimization, RR optimization analysis. After these repeated

optimization process to ensure that users can use normally LTE

wireless

networks.This article focuses Three stages of optimization in

engineering

optimization processes and methods, and introduce the wireless

network

optimization mainly optimization tasks, there are often encountered in the

process of optimization problems and solutions.

Keywords: The TD-LTE Coverage optimization Switch to optimize Interference
