Artiza’s test application has versatile functionalities to evaluate LTE eNB, covering from independent C-plane and U-plane testing to the comprehensive C/U combined testing. The DUT (eNB) is connected to UE and core network, with the Uu interface and the S1/X2 interface respectively. To support the array of functionalities and the parameter settings, the test software includes an easy-to-use configuration tool, Parameter Composer. It allows an intuitive configuration of detail functionalities, and users can check the simulation setting easily. Another powerful feature of our test software is the SDL (Subscription Description Language) Engine, which allows users to create their own test sequences with great flexibility.
UE-SIM Parameter Composer allows users to set parameters for E-UTRAN/Cell/UE/Subscriber/Logical Channel/Sequence, as shown in Figure 1 to 5. Its unique architecture, managing the subscriber table, UE table, and the subscriber table maintained in eNB, enables to simulate a very large number of independent subscribers. Figure 6 shows the overview of the relationship between these tables. Each sequence is configured with its own subscriber table, containing the list of unique subscriber ID. Combination of each sequence and the subscriber ID creates a large group of unique subscribers. From the subscriber groups of all sequences, up to 840 UE connections can be simultaneously simulated by a single cell. The physical characteristics of the UEs are maintained in the UE Table, and each UE can be configured independently for greater flexibility.
