无线市话网络的优化设计与实现
|
摘要
无线网络优化是对投入运行的小灵通无线网络进行参数采集和数据分析,从中找出影响无线网络质量的因素,通过技术手段或参数调整使得无线网络达到最佳运行状态。无线网络优化在使网络资源获得最佳效益的同时,还可以帮助工作人员了解网络的增长趋势,为系统扩容提供依据。
无线网络规划是无线网络优化的前导阶段,良好的无线网络规划可以大大降低网络优化的工作量。但是,无线网络规划阶段不可能面面俱到,考虑不到的一些问题,如无线电波传播的不确定性(如障碍物的阻碍等)、基础设施(新商业区、街道和城区的重新布局)的变化、话务负荷的变化、话务要求和用户对服务质量的要求的变化等因素,都需要依靠网络优化来解决。另一方面,当网络运营商发现网络中存在诸如覆盖不好、话音质量差、掉话、网络拥塞、切换成功率低或未开通某些新功能等问题时,也需要对无线网络进行优化。通过不断的网络优化工作,可以缩短呼叫建立时问、提高通话语音质量、使得网络拥有较高可用性及可靠性、改善覆盖率、降低掉话率及拥塞率、提高接通率及切换成功率和减少用户投拆,最终使小灵通系统成为运营商和客户满意的系统。
在对网络所进行的五年多的维护和优化改造过程中,本文根据网络优化改造的原则、目的和特点,采取了一定的步骤和措施。
PHS business in China along with the wide spread of major north-south, PHS users is also increasing.
PHS system operators and equipment manufacturers gradually found that our mission has been transferred from system construction to how to use the PHS system to better meet user needs and provide satisfactory service up to the user. Wireless network optimization is put into operation the PHS wireless network parameters acquisition and data analysis to find out the factors that affect the quality of the wireless network, through technical means or parameters to adjust the wireless network to achieve the best operating condition. Wireless network optimization of network resources in the best efficiency can also help staff to understand the trend of growth in the network, provide the basis for system expansion. PHS system, including core and radio network in two parts, in which pros and cons of the wireless network portion of the hungry is the system running the performance quality of a deciding factor. Wireless network planning is the leading wireless network optimization stage, a good wireless network planning can significantly reduce the workload of network optimization. However, wireless network planning stage can not cover everything, can not consider some of the problems, such as radio wave propagation of uncertainty (such as the obstacle of the obstacle), infrastructure (the new business district, street and urban re-layout) changes, changes in traffic load, traffic requirements and user requirements for changes in quality of service and other factors, need to rely on network optimization to solve. On the other hand, when the network operators that exist in the network, such as poor coverage, poor voice quality, dropped calls, network congestion, switch or open some of the low success rate of new features and other issues, they need to optimize the wireless network. Through continuous network optimization, you can reduce call setup time and improve the quality of voice, making the network has high availability and reliability, improve coverage and reduce the call drop rate and the congestion rate and improve the connection rate and success rate and reduce the switching user complaints, eventually becoming the PHS system operators and customer satisfaction system.
Network optimization transformation process in general, including:network access through the corresponding performance statistics; as needed to carry out the purpose of statistical data analysis; combined to make the wireless side of the road network assessment test results; made assessment of the network optimization program; under the implementation of the program repeatedly to resolve the existing network failures and problems; on the optimization of the network cycle again after the end of network assessment, network optimization to do reports on the remaining issues rectification proposals for projects to provide the basis for later.
Needs to be stressed is that the network optimization and reconstruction is a long-term work to be periodic, as long as the network, and only the beginning, without end.
Conducted in the network maintenance and optimization of more than five years of renovation process, we transform the network optimization principles, goals and characteristics, to take certain steps and measures, this is the main content of some of our experience and network maintenance transformation of the network optimization steps and measures, and we hope to do in-depth exchanges.
