【摘要】：伴随着.4G时代的到来,作为我国拥有核心自主知识产权的TD-SCDMA的后续演进技术,TD-LTE的发展备受关注。Ir接口作为分布式基站基带单元与射频拉远部分之间的接口,其标准化对LTE测试仪表器的研发具有很大的影响,进行Ir接口协议一致性测试及明确测试用例对TD-LTE的标准化和产业化发展有着重大的意义。本文基于Ir接口协议,针对Ir接口应用层测试,提出链式组网形式下Ir接口测试系统技术解决方案,实现了支持Ir接口协议升级和链式组网规模扩展,具备硬件设备状态监控、Ir接口应用层交互流程测试及故障定位功能的Ir接口组网测试平台。本文对Ir接口组网测试系统的功能需求进行了深入分析,结合所选用的硬件平台,设计了系统的总体框架。本文在链式组网形式下,采用模块化与层次化相结合的设计思想,将系统的实现分为设备控制模块与上位机组网测试软件两部分进行详细说明,在设计过程中,充分的考虑了对Ir接口协议的兼容及升级支持,实现了Ir接口组网测试系统的可视化管理。本文最后进行了系统测试,包括链路连接测试、心跳检测、交互流程测试及测试记录查询测试。测试结果表明,Ir接口组网测试系统各项测试功能正常完成,达到了预期设计目标。
[Abstract]:With the arrival of the age of .4G, the development of TD-LTE, which has the core independent intellectual property rights in China, has attracted much attention. The development of TD-LTE interface is regarded as the interface between the base-band unit of distributed base station and the remote part of radio frequency. Its standardization has great influence on the research and development of LTE test instrumentation. It is of great significance for the standardization and industrialization development of TD-LTE to carry out the consistency test of ir interface protocol and definite test cases. Based on the ir interface protocol, this paper puts forward a technical solution of the ir interface testing system in the form of chain networking, which supports the upgrading of ir interface protocol and the expansion of the scale of the chain network, aiming at the testing of the application layer of the ir interface. The testing platform of ir interface network with the function of hardware device status monitoring and application layer interaction flow testing and fault location. In this paper, the functional requirements of the ir interface networking test system are deeply analyzed, and the overall framework of the system is designed based on the selected hardware platform. In this paper, in the form of chain networking, the realization of the system is divided into two parts: the equipment control module and the host computer networking test software. The compatibility and upgrade support of ir interface protocol are fully considered, and the visual management of ir interface networking test system is realized. At the end of this paper, the system tests are carried out, including link connection test, heartbeat detection, interactive flow test and test record query test. The test results show that the testing functions of the network testing system with ir interface have been completed normally and the expected design goal has been achieved.
