1. Test Cases

Inter-working Design Verification Testing involved two sets of test cases for 20Watt & 60Watt Sites.

For 20W Site configuration, three sets of Inter-Working Parameters were tested, these Parameter Sets are known as TC1, TC2 & TC3

For 60W Site configuration, two sets of Inter-Working Parameters were tested, known as 60W-TC1 & 60W-TC2.

Note that 60W-TC1 Parameters are the same as 20W-TC1

•RSCP measurement is just after the RRC Connection Release (DL-DCCH).

•This can be use to fine tune b2Threshold2RscpUtra, if eventb2 is activated in the eNodeB ( and supported by UE)

• The device that were use during these tests doesn't support event B2.

•WCDMA coverage (90% of RSCP is better than -85dbm- @ re-direction)

•WCDMA_TPL= 35-4.6 +85=115dB

•LTE_TPL= 17+118=135dB

•Delta TPL = 20dB (WCDMA better)

– UE moves from WCDMA (RRC_Idle –NO PDP context) to LTE coverage area.

-> Tracking Area Reject

› Scenario 3:– UE moves from WCDMA ( Active Mode) to LTE coverage and re-

select to LTE-> Successful

UE states and transitions between states from UTRAN to LTE

› LTE cell reselection for UEs in CELL_FACH is not specified by 3GPP and is thus not supported.


TAU Reject

› According to 3GPP Cell Reselection :– In LTE, as in UTRAN, area registration procedures use NAS

signaling. A UE attempting a cell reselection to E-UTRA sends a TA Update (TAU) message to the eNB of the chosen LTE cell and the eNB forwards the TAU message to a chosen MME in the EPC. If the area update procedure is successful the MME replies with a TAU Accept message.

– It is mandatory for a UE in E-UTRA to have a PDN connection (corresponding to a PDP context) defined and this PDN connectionneeds to be retained also when camping in UTRAN. A UE without a PDP context will not be able to make cell reselection to E-UTRA, since the Tracking area update will be rejected

In this example you can see active bearers. (20).

But TEMS does not decode it again.
