This page describes LTE UE signalling conformance tests. LTE UE signalling conformance test specifications are published as mentioned below.

  • User Equipment(UE) conformance specifications; Part 1 PCS(Protocol Conformance Specification): It is defined in 3GPP 36.523-1
  • User Equipment(UE) conformance specifications; Part 2 ICS(Implementation Conformance Statement) : It is defined in 3GPP 36.523-2
  • User Equipment(UE) conformance specifications; Part 3 ATS(Abstract Test Suite) : It is defined in 3GPP 36.523-3

Categories

The test cases are categorized based on different layers used in the LTE protocol stack as well as different functionalities.

  • IDLE MODE
  • LAYER-2 MAC/RLC/PDCP
  • RRC
  • EMM (EPS Mobility Management)
  • ESM (EPS Session Management)
  • Radio bearer

Few of the LTE test cases under these categories are described below.

RRC signalling conformance tests-IDLE
