【摘要】：本人在三星通信研究院實習(xí)期間參與了基站功率優(yōu)化系統(tǒng)的研發(fā)�；镜陌l(fā)射功率在實際工作時一般會保持在最大值,即信號的覆蓋范圍最大,但實際上某些基站不需要用最大的發(fā)射功率就能保證用戶設(shè)備的正常通信,那么基站功率就存在過剩的問題。本系統(tǒng)的目的是通過調(diào)整多個基站的發(fā)射功率來調(diào)整基站各自的信號覆蓋范圍,以達到信號覆蓋范圍和發(fā)射功率之間的均衡,從而優(yōu)化基站的功耗。本系統(tǒng)分為數(shù)據(jù)庫管理、文件傳輸、功率優(yōu)化和日志管理四個功能模塊。其中功率優(yōu)化模塊的主體是對禁忌搜索算法的實現(xiàn)。為了輔助功率優(yōu)化模塊的工作,本人設(shè)計并實現(xiàn)了數(shù)據(jù)庫管理模塊對數(shù)據(jù)庫進行管理,以及文件傳輸模塊對文件進行網(wǎng)絡(luò)傳輸。為了方便功率優(yōu)化模塊的測試,本人設(shè)計并實現(xiàn)了日志管理模塊來對算法的中間值進行記錄。本人在三星通信研究院系統(tǒng)設(shè)計部實習(xí)期間參與了本系統(tǒng)的需求分析、設(shè)計、開發(fā)、測試、維護和版本迭代等工作。具體工作內(nèi)容如下:(1)對系統(tǒng)需求進行分析。通過和同事們深入分析現(xiàn)有系統(tǒng)的不足,制訂了本系統(tǒng)的需求文檔。(2)參與并設(shè)計了系統(tǒng)的架構(gòu)。由于該系統(tǒng)的實際應(yīng)用環(huán)境和開發(fā)環(huán)境不同。系統(tǒng)架構(gòu)的設(shè)計既要考慮Linux的運行環(huán)境,也要考慮Windows開發(fā)環(huán)境的特點。經(jīng)過商議,決定將系統(tǒng)分模塊進行開發(fā)以方便代碼的移植。(3)負責(zé)并開發(fā)了相關(guān)模塊。包括數(shù)據(jù)庫管理、文件傳輸、功率優(yōu)化和日志管理四個模塊,以及相關(guān)數(shù)據(jù)接口的設(shè)計和相關(guān)算法的實現(xiàn)。(4)對測試用例進行設(shè)計并對系統(tǒng)進行功能測試。設(shè)計測試用例要全面考慮,以保證系統(tǒng)功能的完備性和運行結(jié)果的正確性。(5)負責(zé)系統(tǒng)的維護和版本更新。系統(tǒng)會不斷地加入新的需求,也會出現(xiàn)錯誤。本人負責(zé)系統(tǒng)的維護和升級工作。本系統(tǒng)有效代碼3萬余行,目前已更新內(nèi)部版本23次。本系統(tǒng)已發(fā)布beta公共測試版。在實際應(yīng)用中運行良好,在保證通信質(zhì)量的前提下優(yōu)化了基站的發(fā)射功率,降低了基站的功耗。
[Abstract]:I participated in the research and development of base station power optimization system during my internship at Samsung Communications Research Institute. The transmission power of the base station is generally maintained at the maximum value in practice, that is, the signal coverage is the largest. But in fact, some base stations do not need to use the maximum transmission power to ensure the normal communication of the user equipment. Then there is the problem of excess base station power. The purpose of this system is to adjust the respective signal coverage of the base station by adjusting the transmission power of multiple base stations, so as to achieve a balance between the signal coverage and the transmission power. So as to optimize the power consumption of the base station. The system is divided into database management, file transmission, Power optimization and log management are four functional modules. The main part of power optimization module is the implementation of Tabu search algorithm. In order to assist the work of power optimization module, I design and implement the database management module to manage the database. In order to facilitate the test of power optimization module, the file transfer module carries on the network transmission to the file. I designed and implemented the log management module to record the median value of the algorithm. I participated in the system requirements analysis, design, development and testing during the internship in the system design department of Samsung Communication Research Institute. Maintenance and version iteration. The specific work is as follows: 1) Analysis of system requirements. Through in-depth analysis with colleagues of the shortcomings of the existing system, The requirement document of this system is drawn up and the architecture of the system is designed. Because the practical application environment of the system is different from the development environment, the running environment of Linux should be considered in the design of the system architecture. It is also necessary to consider the characteristics of the Windows development environment. After deliberation, it was decided that the system should be divided into modules to facilitate the transplantation of the code.) the system was responsible for and developed related modules, including four modules: database management, file transfer, power optimization and log management. And the design of the related data interface and the implementation of the related algorithms. 4) the design of the test cases and the functional test of the system. The design of the test cases should be considered comprehensively. To ensure the completeness of the system function and the correctness of the running results.) responsible for the maintenance and update of the system. The system will continue to add new requirements. There will be errors. I am responsible for the maintenance and upgrade of the system. The system has more than 30,000 lines of effective code, has updated the internal version 23 times. This system has released the beta public beta version. In practical applications, the system works well. The transmission power of the base station is optimized and the power consumption of the base station is reduced on the premise of ensuring the communication quality.
