This thesis starts with a brief introduction about LTE system and Automated Testing, after which, it describes the implementation of test automation for Mobility Management Entity (MME) of 4G LTE core network. The thesis work is focus on testing of MME logical interfaces s1, s6 and s11. There is a test suite that is developed, and is used to remotely control the Tektronix G35 tester to generate network traffic for testing purpose. Besides, the test suite sends Man Machine Language (MML) commands to the MME hardware platform called ATCA, and periodically collects counters’ data, with which the test suite is able to track the performance of the three interfaces of MME. As a conclusion, automated testing for MME is found to be very important. It provides an efficient way to generate a clear picture of the performance of MME, which is helpful when improving the quality of MME.
