13.1.1.1 Test Purpose (TP)

(1)

with { UE has a default EPS bearer context and dedicated EPS bearer context active and the associated DRBs are established }

ensure that {

when { UE receives downlink data on the radio bearer associated with the default or the dedicated EPS bearer context }

then { UE delivers the downlink data to upper layers }

}

(2)

with { UE has a default EPS bearer context and dedicated EPS bearer context active and the associated DRBs are established }

ensure that {

when { uplink data are submitted for transmission }

then { UE transmits the uplink data on the radio bearer associated with the default EPS bearer context or the dedicated EPS bearer context according to configured TFT}

}

(3)

with { UE has a default EPS bearer context and the dedicated EPS bearer context was deactivated }

ensure that {

when { UE receives downlink data on the radio bearer associated with the default EPS bearer context }

then { UE delivers the downlink data to upper layers }

}

(4)

with { UE has a default EPS bearer context and the dedicated EPS bearer context was deactivated }

ensure that {

when { uplink data are submitted for transmission }

then { UE transmits the uplink data on the radio bearer associated with the default EPS bearer context }
