Implementation Of Cell Reselection Test Cases Based On Ttcn-3in Td-Lte Rrm Conformance Test System

As the evolution of TD-SCDMA system, TD-LTE is submitted by China and has been approved as an international standard by3GPP. TD-LTE terminal RRM conformance test system is one of TD-LTE terminal conformance test defined by3GPP. And it should simulate the wireless propagation condition to test the terminal RRM performance.The performance of cell reselection is an important part of RRM performance.Cell reselection is the mobility behavior in idle mode, and terminal should decide to measure and judge to reselect. There are two cell reselection test cases in TD-LTE terminal RRM conformance test system. They are E-UTRAN TDD-TDD cell re-selection intra-frequency case and E-UTRAN TDD-TDD cell re-selection inter-frequency case.A method to implement cell reselection test cases based on TTCN-3is put forward in this paper. Firstly, the author detailed describes the cell reselection test cases defined by3GPP technical specification, including test purpose, test environment and parameters, test procedures. Secondly, the author detailed analyzes the test parameter in each stage and the judgment of the test points. Thirdly, the author implements the test cases based on TTCN-3language. Finally, the author describes the verification of the implemented results and the analysis of the result.
