DL-DCCH : Cell Update Confirm; UL-DCCH : transfportChannelReconfigurationCompelete之后便出现Drop

如题。
请教各位前辈,
在DT过程中,
UE收到 DL-DCCH: cellUpdateConfirm后,
UE回报 UL-DCCH: transportChannelReconfigurationComplete
UE收到 DL-DCCH: measurementControl;NewPSC
UE回报 UL-DCCH: measurementControlFailure
UE再次收到 DL-DCCH: measurementControl;NewPSC
之后
UL-DCCH: measurementReport;EID = e1a;
DL-DCCH: measurementControl
UL-DCCH: measurementReport;EID = e2f
DL-DCCH: measurementControl
UL-DCCH: measurementReport;EID = e2f
DL-DCCH: measurementControl
接着便只收到BCCH-BCH message,就Drop.
