Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

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 }

}

13.1.1.3.2 Test procedure sequence

Table 13.1.1.3.2-1: Main behaviour

St	Procedure	Message Sequence		TP	Verdict
		U – S	Message
1	SS transmits an RRCConnectionReconfiguration message to establish a data radio bearer. The SS transmits a ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST message activating a new EPS bearer context. The NAS message is included in a RRCConnectionReconfiguration message.	<–	RRCConnectionReconfiguration NAS: ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST	–	–
2	The UE transmits a RRCConnectionReconfigurationComplete message to confirm the establishment of data radio bearer.	–>	RRCConnectionReconfigurationComplete	–	–
3	The UE transmits an ACTIVATE DEDICATE EPS BEARER CONTEXT ACCEPT message.	–>	ULInformationTransfer NAS: ACTIVATE DEDICATE EPS BEARER CONTEXT ACCEPT	–	–

5	The SS transmits one IP packet to the UE on the DRB associated with the default EPS bearer context.	<–	IP packet	–	–
6	Check: Does the UE loop back the IP packet on the DRB associated with the default EPS bearer context?	–>	IP packet	1,2	P

8	Check: Does the UE loop back the IP packet on the DRB associated with the dedicated EPS bearer context?	–>	IP packet	1,2	P
9	SS transmits an RRCConnectionReconfiguration message to release a data radio bearer. The SS transmits a DEACTIVATE EPS BEARER CONTEXT REQUEST including the EPS bearer identity of the dedicated EPS bearer.
