COMPRION SIMfony LTE Already Offering Conformance Test Cases for LTE USAT Terminal Testing Selected by GCF

Paderborn, Germany - COMPRIONs recently launched LTE USAT test bench contains all test cases (TCs) specified by 3GPP TSG CT6 for LTE USAT which have been selected by GCF in the new work item (WI) 137 for USAT interworking with EUTRA/EPC Rel-8.

COMPRION is known for its timely delivery of test benches based on official test standards. The LTE USAT test bench, part of the COMPRION SIMfony LTE solution, was launched before the GCF had selected which of the testcases were to be included in its set of conformance test cases, showing that COMPRION continues to be leader in its field.

The TCs included in the WI-137 and in the COMPRION SIMfony LTE USAT test bench test the enhancements for EUTRA/EPC for the existing USAT proactive commands and
events already defined in previous releases of 3GPP TS 31.124.

USAT testing essential for LTE environment

The correct interworking of LTE terminals with the USIM is a basic part of the E-UTRA/EPC system due to the central role of the USIM as the responsible element for authentication, mobility management and call control handling.

For the TS 31.124 Rel-8 (USAT conformance test specification) new TCs have been defined to cover the enhanced functionalities for the interworking of BIP (bearer independent protocol) and provide local information features with EUTRA/EPC and the newly defined Network Rejection Event.

The correct functioning of the ME with regards to BIP and "provide local information" commands within LTE is essential for network operators to be able to utilize the OTA update of the UICC/USIM in the LTE network.
