【摘要】 GSM网络中的无线参数是指与无线设备和无线资源有关的参数。这些参数对网络中小区的覆盖、业务类型,服务质量等具有至关重要的影响,因此合理调整无线参数以达到均衡话务和提高网络质量的目的是GSM网络规划及优化工作的重要组成部分。本文根据网络在实际运行过程中所表现的各类事件,结合不同地形地貌,对BSC级参数、BTS级参数、邻区参数、切换参数和功率控制参数,从全区级和小区级进行了规划设计。BSS系统中包括BSC和BTS,相应的BSS参数也分为BSC参数和BTS参数,分别控制BSC和BTS模块。在GSM系统中,信令主要集中在了MAP接口、A接口、Ater接口,Abis接口和Um接口。个移动通信网络建成并运行以后,运营商需要对网络的各种结构、配置和参数进行调整,以使网络更合理地工作。其中无线参数的规划设计是指对正在运行的系统,根据实际无线信道特性、话务量特性和信令流量承载情况,通过调整网络中局部或全局的无线参数来提高通信质量,改善网络平均的服务性能和提高设备利用率的过程。实际上,无线参数调整的基本原则是充分利用已有的无线资源,通过业务量分担的方式使全网的业务量和信令流量尽可能均匀,以达到提高网络平均服务水平的目标。最后,将规划设计的无线参数应用于实际,并用实际网络数据进行正确性和有效性的验证,通过在网运行的检验达到了预期的效果。更多还原

【Abstract】 GSM wireless network parameter refers to wireless devices and radio resource-related parameters. These parameters play an important role on the network coverage area, service type, service quality and so on, so adjusting the radio parameters to achieve a reasonable balance network traffic and improve the quality of GSM network is an important part of GSM network planning and optimization.Based on the actual operation of network performance in the various events, with different topography, this article plans and designs the BSC-level parameters, BTS-level parameters, neighbor cell parameters, hand over parameters and power control parameters from the district level and district level.BSS system includes BSC and BTS, so BSS parameters are divided into BSC parameters and BTS parameters, which control the BSC and BTS modules respectively. In the GSM system, signaling is mainly distributed in the MAP interfaces, A interfaces, Ater interfaces, Abis interface and the Um interface.When mobile communication network have been built and put into running, the network operators need to adjust the network structure, configuration and parameters to make the network more reasonable to work. The planning and design of radio parameters refers to the process of adjusting the local or global radio parameters to improve the communication quality, improve the average network services performance and improve equipment utilization, which is based on the actual radio channel characteristics, traffic characteristics and signaling traffic load conditions of the running communication network system.In fact, the basic principle of radio parameter adjustment is to fully utilize the existing wireless resources and use the way of traffic balance to make the whole network traffic and signaling traffic as evenly as possible, to increase the average service level of the network.Finally, the planned and designed radio parameters are practiced in the live network to verify the accuracy and validity in the verification test which achieved the desired results.更多还原
