【摘要】：隨著社會(huì)經(jīng)濟(jì)的不斷發(fā)展,移動(dòng)用戶數(shù)量迅速增長,業(yè)務(wù)種類復(fù)雜多樣和靈活多變對未來的電信運(yùn)營支撐系統(tǒng)提出了更高要求,加快企業(yè)內(nèi)部信息流轉(zhuǎn)的速度、加大企業(yè)內(nèi)部信息共享的力度,已經(jīng)成為提升企業(yè)競爭力的有效手段。廣大用戶對網(wǎng)絡(luò)質(zhì)量的要求和業(yè)務(wù)需求越來越高,如何改善網(wǎng)絡(luò)運(yùn)行性能,提高網(wǎng)絡(luò)服務(wù)質(zhì)量,已成為移動(dòng)通信市場企業(yè)掌握主動(dòng)權(quán)和增強(qiáng)核心競爭力的基本前提。空中接口是移動(dòng)網(wǎng)絡(luò)終端設(shè)備與基站之間的無線接口,根據(jù)使用環(huán)境的不同,各種因素的影響較大,存在很多不穩(wěn)定的因素,空中接口協(xié)議以及信令消息相對有線結(jié)構(gòu)更為復(fù)雜。所以,對移動(dòng)網(wǎng)絡(luò)空中接口的監(jiān)測是網(wǎng)絡(luò)監(jiān)測的重點(diǎn),唯有對其實(shí)現(xiàn)動(dòng)態(tài)監(jiān)測,對網(wǎng)絡(luò)故障的分析才會(huì)更準(zhǔn)確。這也是網(wǎng)絡(luò)規(guī)劃、網(wǎng)絡(luò)評(píng)測和網(wǎng)絡(luò)優(yōu)化所關(guān)注的領(lǐng)域。當(dāng)前的GSM網(wǎng)絡(luò)監(jiān)測手段比較成熟的是Abis接口,A接口和PRI接口電纜接口的測量,國內(nèi)對于無線空中接口的監(jiān)測研究較少,并且移動(dòng)通信網(wǎng)絡(luò)屬于高新產(chǎn)業(yè),發(fā)展速度極快。移動(dòng)通信網(wǎng)絡(luò)更新?lián)Q代快,采用傳統(tǒng)硬件設(shè)備路測形式的參數(shù)監(jiān)測,存在硬件不易更換、通用性較差、無法識(shí)別異常參數(shù)等缺點(diǎn)。因此本軟件在Android智能操作系統(tǒng)為平臺(tái)上設(shè)計(jì),通過硬件平臺(tái)采集數(shù)據(jù),智能終端監(jiān)測參數(shù)以及提供對于發(fā)射站的定位功能。通過針對城區(qū)網(wǎng)絡(luò)優(yōu)化特點(diǎn)以及運(yùn)營商所面對的技術(shù)問題,設(shè)計(jì)了對于空中接口參數(shù)監(jiān)測的程序。針對小區(qū)發(fā)射站位置不明確的問題,通過研究單站無源定位技術(shù),針對RSSI定位技術(shù)的缺點(diǎn),提出了一種利用現(xiàn)代手段,通過獲得的GPS坐標(biāo)和RSSI值來定位發(fā)射站的算法。
[Abstract]:With the continuous development of social economy, the number of mobile users is growing rapidly, and the business types are complex, diverse and flexible, which put forward higher requirements for the future telecom operation support system, and accelerate the speed of internal information flow. Increasing the internal sharing of information has become an effective means to enhance the competitiveness of enterprises. The demand of users for network quality and service demand is more and more high. How to improve the network performance and improve the network service quality has become the basic premise for mobile communication market enterprises to master the initiative and enhance the core competitiveness. The air interface is the wireless interface between the mobile network terminal equipment and the base station. According to the different using environment, the influence of various factors is great, and there are many unstable factors. Air interface protocols and signaling messages are more complex than wired structures. Therefore, the monitoring of mobile network air interface is the focus of network monitoring. Only by implementing dynamic monitoring, can the analysis of network faults be more accurate. This is also the area of concern for network planning, network evaluation and network optimization. The current monitoring means of GSM network are the measurement of Abis interface A interface and PRI interface cable interface. There is less research on wireless air interface in China, and mobile communication network belongs to high and new industry, and the development speed is very fast. The mobile communication network is updated quickly, and the traditional hardware device is used to monitor the parameters. The hardware is not easy to change, the generality is poor, and the abnormal parameters can not be identified. Therefore, the software is designed on the platform of Android intelligent operating system. It collects data through hardware platform, monitors the parameters of intelligent terminal and provides the location function for the transmitting station. According to the characteristics of urban network optimization and the technical problems faced by operators, a program for monitoring air interface parameters is designed. In order to solve the problem of unclear location of the transmission station in the cell, a new algorithm is proposed to locate the transmitting station by using the modern means, by using the GPS coordinates and RSSI values obtained by studying the single station passive location technology and the shortcomings of the RSSI positioning technology.
