8.1.4a RRC connection release requested by upper layers
25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS
8.1.4a.1 General
The purpose of this procedure is to release the RRC connection and bar the current cell or cells. The procedure is requested by upper layers when they determine that the network has failed an authentication check [5].
8.1.4a.2 Initiation
If the upper layers request the release of the RRC connection, the UE shall:
1> release all its radio resources;
1> enter idle mode;
1> perform other actions when entering idle mode from connected mode as specified in subclause 8.5.2;
1> if the UE was in CELL_DCH state prior to entering idle mode:
2> consider all cells that were in the active set prior to entering idle mode to be barred according to [4]; and
2> consider the barred cells as using the value "allowed" in the IE "Intra-frequency cell re-selection indicator", and the maximum value in the IE "Tbarred".
1> if the UE was in CELL_FACH or CELL_PCH or URA_PCH state prior to entering idle mode:
2> consider the cell on which the UE was camped prior to entering idle mode to be barred according to [4]; and
2> consider the barred cell as using the value "allowed" in the IE "Intra-frequency cell re-selection indicator", and the maximum value in the IE "Tbarred".
