【摘要】：第二代和第三代移動(dòng)通信技術(shù)已經(jīng)深入到人們的生活、辦公、娛樂各個(gè)方面,作為第四代移動(dòng)通信技術(shù)的LTE基站的質(zhì)量和可靠性也越來越受到關(guān)注,尤其是TD-LTE基站的衰落性能。由于TD-LTE基站具有測(cè)試任務(wù)多,硬件接口比較多、需求變化快、使用環(huán)境多樣和多測(cè)試終端等不確定等特點(diǎn),測(cè)試工程師傳統(tǒng)的手動(dòng)測(cè)試技術(shù)和方法已無法適應(yīng)TD-LTE基站衰落性測(cè)試的挑戰(zhàn),不能對(duì)TD-LTE基站衰落性測(cè)試進(jìn)行作業(yè)流程的管理,無法滿足基站衰落性測(cè)試的需要。上海貝爾公司開發(fā)和提供的測(cè)試平臺(tái)EASYTEST是一個(gè)通用工具,提供了UMTS和LTE集成測(cè)試自動(dòng)化解決方案。EASYTEST測(cè)試平臺(tái)在TD-LTE基站基本功能測(cè)試中得到了廣泛應(yīng)用,但是對(duì)TD-LTE的基站衰落自動(dòng)化測(cè)試還處于探索階段,衰落自動(dòng)化測(cè)試的需求尚未統(tǒng)一。如何建立和完善一個(gè)能夠有效自動(dòng)化的TD-LTE自動(dòng)化測(cè)試系統(tǒng),是TD-LTE基站衰落性測(cè)試急需解決的一個(gè)問題。本文基于TD-LTE基站衰落原理和EASYTEST技術(shù),設(shè)計(jì)了一個(gè)基于TD-LTE基站衰落自動(dòng)化測(cè)試系統(tǒng)。首先本文對(duì)TD-LTE基站衰落自動(dòng)化測(cè)試的需求進(jìn)行了分析,總結(jié)了當(dāng)前問題,接著通過用例圖、流程圖等方法著重分析了UE自動(dòng)介入、App server發(fā)數(shù)據(jù)包、選擇衰落信道模型、獲取海斯UE log、轉(zhuǎn)換海斯UE log成csv文件、上傳UE log的csv文件到log server、導(dǎo)入數(shù)據(jù)庫(kù)以及重啟基站的功能的業(yè)務(wù)流程和需求。接著,詳細(xì)闡述了TD-LTE基站衰落自動(dòng)化測(cè)試系統(tǒng)的系統(tǒng)架構(gòu);然后對(duì)衰落自動(dòng)化測(cè)試系統(tǒng)最主要的三個(gè)子系統(tǒng)(下行衰落自動(dòng)化測(cè)試子系統(tǒng)、上行衰落自動(dòng)化測(cè)試子系統(tǒng)、上下行全衰落自動(dòng)化測(cè)試子系統(tǒng))進(jìn)行了設(shè)計(jì)和實(shí)現(xiàn)。此外,本文詳細(xì)描述了啟動(dòng)衰落模型子系統(tǒng),上行、下行獲取UE的log方式的方式,轉(zhuǎn)換上行、下行的UE log到csv文件的功能,以及全衰落測(cè)試中建立專有承載等關(guān)鍵技術(shù)的實(shí)現(xiàn)方法。結(jié)合實(shí)際測(cè)試任務(wù),本文設(shè)計(jì)了功能測(cè)試、關(guān)鍵功能測(cè)試、系統(tǒng)整合測(cè)試的測(cè)試用例,針對(duì)系統(tǒng)整合測(cè)試中出現(xiàn)的問題,進(jìn)行了代碼優(yōu)化和調(diào)整。從測(cè)試結(jié)果看,系統(tǒng)的功能和性能能夠滿足當(dāng)初設(shè)計(jì)的指標(biāo)和要求。目前該系統(tǒng)已經(jīng)應(yīng)用于上海貝爾公司的TD-LTE基站衰落測(cè)試。系統(tǒng)運(yùn)行結(jié)果表明,與傳統(tǒng)的測(cè)試工程師手動(dòng)測(cè)試相比,流程自動(dòng)化程度達(dá)到90%以上,壓力測(cè)試正確率達(dá)到99%以上,測(cè)試效率提高近7倍,測(cè)試速度加快,解放了測(cè)試工程師的精力和時(shí)間,同時(shí)也為項(xiàng)目管理者提供了更多的時(shí)間的便利。
[Abstract]:The second and third generation mobile communication technology has been deeply into people's life, office, entertainment, as the fourth generation of mobile communication technology, the quality and reliability of the LTE base station has been paid more and more attention, especially the fading performance of the TD-LTE base station. Because the TD-LTE base station has many testing tasks, more hardware interfaces, rapid change of requirements, various environments and many test terminals, etc. The traditional manual testing techniques and methods used by test engineers can not meet the challenge of TD-LTE base station fading test, nor can they manage the operation flow of TD-LTE base station fading test, nor can they meet the needs of base station fading test. EASYTEST, a testing platform developed and provided by Shanghai Bell Company, is a universal tool, which provides UMTS and LTE integrated test automation solution .EASYTEST test platform has been widely used in the basic function testing of TD-LTE base station. But the TD-LTE base station fading automation test is still in the exploration stage, and the requirement of the fading automation test is not unified. How to establish and perfect a TD-LTE automated test system which can be effectively automated is an urgent problem to be solved in TD-LTE base station fading test. Based on the principle of TD-LTE base station fading and EASYTEST technology, an automatic test system based on TD-LTE base station fading is designed in this paper. Firstly, this paper analyzes the requirements of TD-LTE base station fading automation test, summarizes the current problems, and then analyzes the UE automatic interference in the application server sending data packets through the use case diagram, flow chart and other methods, and selects the fading channel model. Get Hayes UE log, convert Hayes UE log into csv file, upload UE log csv file to log server, import database and reboot the business flow and requirement of base station function. Then, the system architecture of the TD-LTE base station fading automation test system is described in detail, and then the three main subsystems (downlink fading automation test subsystem, uplink fading automatic test subsystem) of the fading automation test system are introduced. The whole downlink and downlink automatic test subsystem is designed and implemented. In addition, this paper describes in detail how to start the fading model subsystem, how to obtain UE log from uplink and downlink, and how to convert UE log from uplink and downlink to csv files. And the realization method of the key technology, such as establishing the proprietary load in the whole fading test. Combining with the actual test task, this paper designs the test cases of function test, key function test and system integration test, and optimizes and adjusts the code for the problems in the system integration test. From the test results, the function and performance of the system can meet the original design indicators and requirements. At present, the system has been applied to the TD-LTE base station fading test of Shanghai Bell Company. The system results show that compared with the traditional test engineers, the degree of automation is over 90%, the correct rate of stress testing is over 99%, the efficiency of test is improved nearly 7 times, and the test speed is accelerated. Liberates the test engineer's energy and time, also provides more time convenience for the project manager.
