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.
• IDLE MODE
• LAYER-2 MAC/RLC/PDCP
• 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
|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
|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
|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|
|EMM common procedures||reallocation procedure, authentication, security mode control procedure, identification, EMM information procedures|
|EMM specific procedures||Attach, detach, tracking area update procedures|
|EMM connection management procedures||service request procedures, paging procedures|
|NAS security||NAS ciphering, integrity protection|
|EPS session management|| Dedicated EPS bearer context activation, context modification, de-activation,UE requested PDN connectivity,
UE requested PDN disconnect, UE requested bearer resource allocation, UE requested resource release
