Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Packet Core (EPC); User Equipment (UE) conformance specification; Part 3: Test suites
The present document specifies the protocol and signalling conformance testing in TTCN-3 for the 3GPP UE at the UE‑E-UTRAN radio interface.
The following TTCN test specification and design considerations can be found in the present document:
-	the test system architecture;
-	the overall test suite structure;
-	the test models and ASP definitions;
-	the test methods and usage of communication ports definitions;
-	the test configurations;
-	the design principles and assumptions;
-	TTCN styles and conventions;
-	the partial PIXIT proforma;
-	the test suites.
The Abstract Test Suites designed in the document are based on the test cases specified in prose (3GPP TS 36.523‑1 [1]). The applicability of the individual test cases is specified in the test ICS proforma specification (3GPP TS 36.523‑2 [1]).
The present document is valid for TTCN development for LTE, LTE-Advanced and LTE-Advanced Pro (including NB-IoT) UE conformance test according to 3GPP Releases starting from Release 8 up to the Release indicated on the cover page of the present document.
In the remainder of the present document, unless explicitly stated otherwise, the term E-UTRA(N) implicitly refers to the Wideband part of E-UTRA(N) known as WB-E-UTRA(N). The Narrowband part of E-UTRA(N) is always explicitly referred to as NB-IoT.
