Function Test Of Operation And Maintenance For WCDMA Nodeb

With the rapid evolution of the wireless technology, the service quality and service type provided by mobile telecommunication system has been paid more attention to, its reliability and ease of use has been set higher requirements.High speed, low delay, the good experience business increasingly recognized by users and operators. Operators can provide more services and applications via more efficient and economic method, thus they get better returns and users will enjoy more business. Objective of mobile telecommunication system is supporting higher data rate, low delay, low cost, optimizing the system coverage and capacity. Among them 3G telecommunication system is especially suitable for high density populated area in the city provide large capacity as well as voice and multimedia business.Data Service is the main business of WCDMA wireless network, performance of data upload and download will have a direct impact on the end user experience. NodeB offers flexible configuration, supporting 3 sectors, each sector can support 3 carriers, and NodeB can effectively solve the traffic capacity of the hot spot regions. At present, more than 70 percent data service is indoor business, operator provide good WCDMA indoor coverage.Operation and maintenance functions that provide users with safety data,configuration management,alarm management, performance testing and environmental monitoring, and the quality such as above not only affect the customer's satisfaction, but also is related to operating costs problems,which directly affects operators profits. Therefore, operation and maintenance of quality is good or bad, is the key factor to retain customers and reap greater profits.This thesis includes test requirement analysis, test plan, test scheme design, test case design, and implementation, execution analysis etc.The thesis introduces the topic research background and the development of mobile telecommunications, detailed state the main characteristics of NodeB, test procedure of operation and maintenance verification, detailed explain function scope and content, detailed described test requirement analysis, test scheme design and case design.According to operation and maintenance function test plan, introduces the test environment, test tools,test execution, analyze test results and strengthen the typical test case analysis.
