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
Categories
The test cases are categorized based on different layers used in 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
| 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 |
|---|---|
| MAC layer | mapping between logical and transport channels, RACH, DL-SCH and UL-SCH data transfer, MAC re-configuration, DRX operation, transport block size support |
| RLC layer | Acknowledged mode, unacknowledged mode |
| PDCP Layer | maintenance of PDCP sequence numbers for radio bearers, robust header compression testing, PDCP ciphering, PDCP handover, PDCP integrity protection, U-plane latency performance |
EPS tests-EMM,ESM
| Subgroup | Reference/Description |
|---|---|
