Research And Implementation Of Time Accuracy Test Cases Based On RRM Conformance Test System

LTE project is an evolution of3G. As one of the fourth generation mobile communication technology,it has two formats: frequency division duplex system FDD-LTE and time division duplex system TDD-LTE. TDD-LTE is China’s leading4G technology which can be more flexible using of spectrum resources asymmetric.3GPP organised LTE as the third generation mobile communication system long term evolution for inter-system radio resource management conformance testing to ensure the quality of the terminal so as to satisfy the requirements of network authentication.LTE system supports two Communication standard: FDD-LTE and TDD-LTE. frequency division duplex LTE system and time division duplex system. the4G technology TDD-LTE model as we all know TD-LTE,has the advantage of more flexible use of asymmetric spectrum resources.Time-based precision test system terminal RRM conformance test system including the transmission time accuracy test case and timing advance adjustment accuracy test case. Terminal transmission time accuracy test is to verify the terminal in the connected state, the uplink transmission radio frame corresponds with the down-link transmission capacity of wireless frames change. Terminal timing advance adjustment accuracy test case is aimed at the connected state, the ability to adjust the timing advance.In the process of implementation, based on the platform of the TD-LTE terminal RRM conformance test system, we research and finish time measurement accuracy of the test cases. With process flow of test cases, parameter configuration of the code, finally using a variety of terminals to prove time accuracy test cases and get the right conclusion.Currently, the test cases have been in the RRM conformance testing instrument with a number of terminal manufacturers completing the GCF certification. RRM conformance testing instrument has been successfully commercialized, will be widely used in the development of the terminal, commissioning, production and certification.
