The IP Multimedia Subsystem (IMS) is used to enable SMS or voice services within the LTE network. The IP Multimedia Services Identity Module (ISIM) is an application running on a UICC smart card. It contains parameters for identifying and authenticating the user to the IMS. The ISIM coexists with the USIM or the CSIM on a multi-application UICC.
The new SIMfony RS IMS test solution tests the device interaction with the ISIM application. COMPRION SIMfony RS IMS consists of the Rohde & Schwarz LTE network simulator R&S®CMW500, the IMS Simulation R&S®CMW-KF576 and the COMPRION IT³/IT³ Prove! UICC/USIM/CSIM/ISIM Simulator.
With the new IMS ISIM tests COMPRION now adds the required ISIM chapter of the VZW COMPLIANCE TEST PLAN LTE DEVICE-UICC (USIM, ISIM) INTERACTION, VERSION 6.0 (09/2011) to its handset conformance test platform. COMPRION is already offering the respective test case packages LTE USIM/USAT, as well as CDMA2K CSIM/CCAT for LTE Multimode Terminal testing.
