Design And Implement The Testing Platform Of The TD-LTE Broadband Multimedia Cluster System

With the rapid development of mobile communication technology,the communication system is moving towards the development of business diversification, data bandwidth and system IP.In addition,the present narrow band cluster communication system can not meet the needs of the development of data services. Compared with the traditional narrow band trunking communication technology, TD-LTE technology shows a revolutionary improvement in data transmission and spectral efficiency,so broadband multimedia cluster communication system based on TD-LTE is one of the main developing directions of trunking communication system in the future.The TD-LTE broadband trunking communication system protocol stack test platform is studied in this paper. The main research work includes the development of protocol stack testing, analyzing and performance assessment, for broadband trunking system.The second chapter embarks from the architecture requirements of the LTE broadband multimedia cluster communication system. Here, the testing methods for broadband trunking system protocol stack are studied and the performance test of the protocol stack is further described,based on which the subsequent study is carried out.Based on the second chapter, the functional requirements analysis of the protocol stack is put forward in the third chapter, laying foundation and providing a theoretical support for the subsequent chapters.Also the measurement platform is designed and implemented according to this demand. The Measurement platform mainly consists of two parts: test equipment and device under test. The test equipment is mainly the debugging UI interface and its communication module. And the device under test includes dbgSrv and kernel protocol stack. Different modules use different means of communication to communicate. Functional implementation is realized for the demand proposed in the second chapter based on this module partition, focusing on realizing the function of the demand.In the fourth chapter, a functional verification of the protocol stack debugging platform is implemented. Validation is mainly divided into three aspects: the correctness of debugging platform implementation, of implementation of a protocol stack and of the interaction between the protocol stack and measuring platform. And then through repeated verification, we will improve the function of debugging platform.Finally, the whole research work is summarized and the next step of work is pointed out.
