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.
