TSG-T WG1/SIG: User Equipment (UE) protocol conformance specification (Prose description); Part 1: Protocol conformance specification Abstract of document: This specification is the first part of a multi-part specification describing in prose a suite of conformance tests for 3rd Generation User Equipment (UE). The tests are intended to ensure that User Equipment for 3GPP systems conform to the relevant 3GPP Technical Specifications. The other parts of the multi-part specification are TS 34.123-2, which contains a pro-forma for the Implementation Conformance Statement (ICS), and TS 34.123-3, which contains a detailed and executable description of the test cases written in a standard testing language, TTCN. Contentious Issues: Timely completion of this specification depends upon the availability of the core specifications for which it provides conformance tests. Specifications with the largest impact are TS 24.008, TS 24.331, TS 24.321 and TS 24.322.
