Method And Achievement For Rapid And Non-Signaling Multiple Test Based On LTE

The current terminal products support a growing number of communication protocols. Terminal product testing program for LTE is almost a hundred more than that for2G or3G. Increasing for the time of test means the increasing for the cost of test. According to the measured data from multiple vendors, non-signaling test can speed up the time of test for more than50%in3G, which brings the opportunity for the introduction of4G non-signaling test. In the future, mobile phone test mode will shift from signaling to non-signaling, further into a fast sequence of non-signaling multiple test.The main content of this thesis is as follows:Firstly, an overview of the characteristics of the fast sequence non-signaling test, offers the background and importance of the subject. Based on this, providing a proper plan and goal for fast sequence non-signaling test, the contents mainly include the architecture of LTE system simulation platform. I will introduce the advantages of fast sequence non-signaling test and the principle for the switch of the sequence. Then accomplish methods and results for needs. Downlink: Introduction of a single specific sequence LTE downlink signal generated by the configuration list, sending, receiving and detecting the indicators. Uplink: uplink synchronization, receiving the signal from the terminal and collecting data according to different requirements of comprehensive test and measurement items, doing the related calculation. Uplink and downlink can be open at the same time.Now the achievement has been used in commercial test set successfully.
