Transmission of RRCConnectionRequest |
Reception of RRCConnectionSetup or RRCConnectionReject message, cell re-selection and upon abortion of connection establishment by upper layers |
Perform the actions |
| T301 |
Transmission of RRCConnectionReestabilshmentRequest |
Reception of RRCConnectionReestablishment or RRCConnectionReestablishmentReject message as well as when the selected cell becomes unsuitable |
Go to RRC_IDLE |
| T303 |
Access barred while performing RRC connection establishment for mobile originating calls |
Upon entering RRC_CONNECTED and upon cell re-selection |
Inform upper layers about barring alleviation as specified |
| T304 |
Reception of RRCConnectionReconfiguration message including the MobilityControl Info or
reception of MobilityFromEUTRACommand message including CellChangeOrder |
Criterion for successful completion of handover to EUTRA or cell change order is met (the criterion is specified in the target RAT in case of inter-RAT) |
In case of cell change order from E-UTRA or intra E-UTRA handover, initiate the RRC connection re-establishment procedure; In case of handover to E-UTRA, perform the actions defined in the specifications applicable for the source RAT. |
| T305 |
Access barred while performing RRC connection establishment for mobile originating signalling |
Upon entering RRC_CONNECTED and upon cell re-selection |
Inform upper layers about barring alleviation as specified |
| T310 |
Upon detecting physical layer problems i.e. upon receiving N310 consecutive out-of-sync indications from lower layers |
Upon receiving N311 consecutive in-sync indications from lower layers, upon triggering the handover procedure and upon initiating the connection re-establishment procedure |
If security is not activated: go to RRC_IDLE else: initiate the connection re-establishment procedure |
| T311 |
Upon initiating the RRC connection re-establishment procedure |
Selection of a suitable E-UTRA cell or a cell using another RAT. |
Enter RRC_IDLE |
| T320 |
Upon receiving t320 or upon cell (re)selection to E-UTRA from another RAT with validity time configured for dedicated priorities (in which case the remaining validity time is applied). |
Upon entering RRC_CONNECTED, when PLMN selection is performed on request by NAS, or upon cell (re)selection to another RAT (in which case the timer is carried on to the other RAT). |
Discard the cell reselection priority information provided by dedicated signalling. |
| T321 |
Upon receiving measConfig including a reportConfig with the purpose set to reportCGI |
Upon acquiring the information needed to set all fields of globalCellId for the requested cell, upon receiving measConfig that includes removal of the reportConfig with the purpose set to reportCGI |
Initiate the measurement reporting procedure, stop performing the related measurements and remove the corresponding measId |
