LTE UE Signalling Conformance Tests

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


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

Subgroup Reference/Description
Pure E-UTRAN Environment tests cell re-selection, PLMN selection in only LTE environment
Multimode environment tests UE 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 tests UE in closed group cells

RRC Connected tests

Subgroup Reference/Description
RRC connection management procedures Paging,RRC connection establishment and release procedures
RRC connection reconfiguration bearer setup, Radio resource re-config., radio bearer release, intra LTE cell handover procedures
Measurement configuration control, Measurement config. reporting Intra LTE measurements and Inter RAT measurements
Inter-RAT handover Between E-UTRA, UTRAmGERAN, HRPD, 1xRTT
Other tests Radio link failure,downlink and uplink direct transfer, UE capability transfer

Layer-2 signalling tests

Subgroup Reference/Description
