【摘要】：第二代和第三代移動通信技術已經深入到人們的生活、辦公、娛樂各個方面,作為第四代移動通信技術的LTE基站的質量和可靠性也越來越受到關注,尤其是TD-LTE基站的衰落性能。由于TD-LTE基站具有測試任務多,硬件接口比較多、需求變化快、使用環(huán)境多樣和多測試終端等不確定等特點,測試工程師傳統(tǒng)的手動測試技術和方法已無法適應TD-LTE基站衰落性測試的挑戰(zhàn),不能對TD-LTE基站衰落性測試進行作業(yè)流程的管理,無法滿足基站衰落性測試的需要。上海貝爾公司開發(fā)和提供的測試平臺EASYTEST是一個通用工具,提供了UMTS和LTE集成測試自動化解決方案。EASYTEST測試平臺在TD-LTE基站基本功能測試中得到了廣泛應用,但是對TD-LTE的基站衰落自動化測試還處于探索階段,衰落自動化測試的需求尚未統(tǒng)一。如何建立和完善一個能夠有效自動化的TD-LTE自動化測試系統(tǒng),是TD-LTE基站衰落性測試急需解決的一個問題。本文基于TD-LTE基站衰落原理和EASYTEST技術,設計了一個基于TD-LTE基站衰落自動化測試系統(tǒng)。首先本文對TD-LTE基站衰落自動化測試的需求進行了分析,總結了當前問題,接著通過用例圖、流程圖等方法著重分析了UE自動介入、App server發(fā)數據包、選擇衰落信道模型、獲取海斯UE log、轉換海斯UE log成csv文件、上傳UE log的csv文件到log server、導入數據庫以及重啟基站的功能的業(yè)務流程和需求。接著,詳細闡述了TD-LTE基站衰落自動化測試系統(tǒng)的系統(tǒng)架構;然后對衰落自動化測試系統(tǒng)最主要的三個子系統(tǒng)(下行衰落自動化測試子系統(tǒng)、上行衰落自動化測試子系統(tǒng)、上下行全衰落自動化測試子系統(tǒng))進行了設計和實現(xiàn)。此外,本文詳細描述了啟動衰落模型子系統(tǒng),上行、下行獲取UE的log方式的方式,轉換上行、下行的UE log到csv文件的功能,以及全衰落測試中建立專有承載等關鍵技術的實現(xiàn)方法。結合實際測試任務,本文設計了功能測試、關鍵功能測試、系統(tǒng)整合測試的測試用例,針對系統(tǒng)整合測試中出現(xiàn)的問題,進行了代碼優(yōu)化和調整。從測試結果看,系統(tǒng)的功能和性能能夠滿足當初設計的指標和要求。目前該系統(tǒng)已經應用于上海貝爾公司的TD-LTE基站衰落測試。系統(tǒng)運行結果表明,與傳統(tǒng)的測試工程師手動測試相比,流程自動化程度達到90%以上,壓力測試正確率達到99%以上,測試效率提高近7倍,測試速度加快,解放了測試工程師的精力和時間,同時也為項目管理者提供了更多的時間的便利。
[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.
