LTE UE Signalling Conformance Tests

lte ue testing conformance testing signalling protocol stack

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

SubgroupReference/Description
Pure E-UTRAN Environment testscell re-selection, PLMN selection in only LTE environment
Multimode environment testsUE in inter-RAT selection, cell selection and re-selection under multi-RAT environment housing all the RATs ETRAN, UTRAN and GERAN
closed subscriber group cells testsUE in closed group cells

RRC Connected tests
