8.2.5.4.1 Definition
8.2.5.4.2 Conformance requirement
If the variable INVALID_CONFIGURATION is set to TRUE due to the received TRANSPORT FORMAT COMBINATION CONTROL message the UE shall:
1> if the TRANSPORT FORMAT COMBINATION CONTROL message was received on AM RLC:
2> keep the TFC subset existing before the TRANSPORT FORMAT COMBINATION CONTROL message was received;
2> transmit a TRANSPORT FORMAT COMBINATION CONTROL FAILURE message on the DCCH using AM RLC;
2> set the IE "RRC transaction identifier" in the TRANSPORT FORMAT COMBINATION CONTROL FAILURE message to the value of "RRC transaction identifier" in the entry for the TRANSPORT FORMAT COMBINATION CONTROL message in the table "Accepted transactions" in the variable TRANSACTIONS; and
2> clear that entry;
2> set the IE "failure cause" to "invalid configuration";
2> when the TRANSPORT FORMAT COMBINATION CONTROL FAILURE message has been submitted to lower layers for transmission the procedure ends.
1> if the TRANSPORT FORMAT COMBINATION CONTROL message was received on UM RLC:
2> ignore the TRANSPORT FORMAT COMBINATION CONTROL message.
Reference
3GPP TS 25.331 clause 8.2.5.4, 8.2.5.5
8.2.5.4.3 Test purpose
To confirm that the UE transmits a TRANSPORT FORMAT COMBINATION CONTROL FAILURE message on the DCCH using AM RLC if it receives a TRANSPORT FORMAT COMBINATION CONTROL message including an invalid configuration.
8.2.5.4.4 Method of test
Initial Condition
System Simulator: 1 cell.
UE: DCCH+DTCH_DCH (state 6-9 or state 6-10) as specified in clause 7.4 of TS 34.108, depending on the CN domain(s) supported by the UE.
Test Procedure
The UE is in CELL_DCH state. SS then send a MEASUREMENT CONTROL message to UE. The UE shall perform periodical traffic volume measurement according to this message and then transmit MEASUREMENT REPORT message back to SS. SS transmits a TRANSPORT FORMAT COMBINATION CONTROL message including some IEs set to get an invalid configuration. The UE keeps its current configuration and transmits a TRANSPORT FORMAT COMBINATION CONTROL FAILURE message on the DCCH using AM RLC, setting the value "invalid configuration" to IE "failure cause". UE shall continue its traffic volume measurement and send MEASUREMENT REPORT messages back to SS periodically.
