8.6.2 UTRAN mobility information elements

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

8.6.2.1 URA identity

The UE shall:

1> if the IE "URA identity" is included in a received message:

2> if the IE "RRC State Indicator" is included and set to "URA_PCH":

3> store this URA identity in the variable URA_IDENTITY;

3> after sending a possible message to UTRAN and entering URA_PCH state as specified elsewhere, read system information block type 2 in the selected cell;

3> if the stored URA identity in the variable URA_IDENTITY is not included in the list of URA identities in System Information Block type 2 in the selected cell, the list of URA identities in system information block type 2 is empty or if the system information block type 2 can not be found, a confirmation error of URA identity list has occurred:

4> if no URA update procedure is ongoing:

5> initiate a URA update procedure after entering URA_PCH state; see subclause 8.3.1.2.

4> if a URA update procedure is ongoing:

5> take actions as specified in subclause 8.3.1.10.

1> if the IE "URA identity" is not included in a received message:

2> if the IE "RRC State Indicator" is included and set to " URA_PCH":

3> after sending a possible message to UTRAN and entering URA_PCH state as specified elsewhere, read System Information Block type 2 in the selected cell;

3> if System Information Block type 2 in the selected cell contains a single URA identity:

4> store this URA identity in the variable URA_IDENTITY.

3> if System Information Block type 2 of the selected cell contains more than one URA identity, the list of URA identities in system information block type 2 is empty or if the system information block type 2 can not be found, a confirmation error of URA identity list has occurred:

4> if no URA update procedure is ongoing:

5> initiate a URA update procedure after entering URA_PCH state, see subclause 8.3.1.2.

4> if a URA update procedure is ongoing:

5> take actions as specified in subclause 8.3.1.10.

8.6.2.2 Mapping info

For FDD, 3.84 Mcps TDD and 7.68 Mcps TDD, if the IE "Mapping info" is received, the UE shall in this version of the specification:

1> ignore the contents of this IE.

For 1.28 Mcps TDD, if the IE "Mapping info" is received, the UE shall:

1> if the IE "Map parameter 1" is included, interpret the IE "Map parameter 1" as IE "UpPCH Position Info":

2> store and use the UpPCH position indicated by the IE "UpPCH Positon Info". The calculation of the uplink access position is described in [33].

1> if the IE "Map parameter 1" is not included:

2> use the UpPTS as the default UpPCH position.

1> ignore other contents of the IE "Mapping info".

8.6.2.3 RNC support for change of UE capability

The UE shall:

1> if the IE "RNC support for change of UE capability" is included in a received message:

2> set the variable RNC_CAPABILITY_CHANGE_SUPPORT to the value of the IE "RNC support for change of UE capability".

8.6.2.4 CSG PSC Split Information

The UE shall:

1> if the IE "CSG PSC Split Information" is included in a received message:

2> consider the CSG PSC split information received on this cell to be valid for:

3> the UARFCN of the carrier on which it was received;

3> any cell not referenced in SIB18, or when SIB18 is not broadcast, while the cell the UE is camped on has a PLMN which is the same as the PLMN of the cell where the CSG PSC split information was received;

3> any cell referenced in SIB18 that has the same PLMN as the PLMN of the cell in which the CSG PSC split information was received;

3> while UE is not in Any Cell Selection state [4];

3> 24 hours from the time it was received.

NOTE 1: If the IE "CSG PSC Split Information" is received in both SIB3 and SIB11bis in the same cell then UE behaviour is unspecified.

NOTE 2: The PLMN of a cell in the above paragraph is the PLMN in IE ‘PLMN identity’ of that cell.

NOTE 3: The 6 hour validity restriction (section 8.1.1.6) does not apply to this field.

8.6.2.5 E-UTRA detection

If the IE "E-UTRA detection" is included in a received message and set to TRUE and the UE is in CELL_PCH, URA_PCH state or idle mode, the UE may detect the presence of a E-UTRA cell on a frequency with a priority lower than the current UTRA cell and report the information to the NAS.
