1> set the IE "Received message type" to ASSISTANCE DATA DELIVERY; and
1> set the IE "RRC transaction identifier" to the value of "RRC transaction identifier" in the entry for the
ASSISTANCE DATA DELIVERY message in the table "Rejected transactions" in the variable
TRANSACTIONS; and
1> clear that entry;
1> include the IE "Protocol error information" with contents set to the value of the variable
PROTOCOL_ERROR_INFORMATION.
1> when the RRC STATUS message has been submitted to lower layers for transmission:
2> continue with any ongoing processes and procedures as if the invalid ASSISTANCE DATA DELIVERY
message has not been received.
8.5 General procedures
8.5.1 Selection of initial UE identity
The purpose of the IE "Initial UE identity" is to provide a unique UE identification at the establishment of an RRC
connection. The type of identity shall be selected by the UE according to the following.
If the UE is operating in "GSM-MAP mode", the UE shall choose "UE id type" in the IE "Initial UE identity" with the
following priority:
1. TMSI (GSM-MAP): The TMSI (GSM-MAP) shall be chosen if provided by upper layers. The IE "LAI" in the
IE "Initial UE identity" shall also be present when TMSI (GSM-MAP) is used, for making it unique.
2. P-TMSI (GSM-MAP): The P-TMSI (GSM-MAP) shall be chosen if provided by upper layers and no TMSI
(GSM-MAP) is available. The IE "RAI" in the IE "Initial UE identity" shall in this case also be present when P-
TMSI (GSM-MAP) is used, for making it unique.
3. IMSI (GSM-MAP): The IMSI (GSM-MAP) shall be chosen if provided by upper layers and no TMSI (GSM-
MAP) or P-TMSI is available.
4. IMEI: The IMEI shall be chosen when none of the above three conditions are fulfilled.
When being used, the IEs "TMSI (GSM-MAP)," "P-TMSI (GSM-MAP)", "IMSI (GSM-MAP)", "LAI" and "RAI" shall
be set equal to the values provided by upper layers. The "P-TMSI (GSM-MAP)" and "RAI" may be mapped from a
valid GUTI..
If the UE is operating in "ANSI-41 mode", the UE shall choose "UE id type" in the IE "Initial UE identity" according to
the procedure specified in the 3GPP2 document "3GPP2 C.P0004-A".
8.5.2 Actions when entering idle mode from connected mode
When entering idle mode from connected mode, the UE shall:
1> clear or set variables upon leaving UTRA RRC connected mode as specified in subclause 13.4;
1> stop timer T323 if it is running;
1> clear the variable SYSTEM_INFORMATION_CONTAINER;
1> if the RRC CONNECTION RELEASE message was received and the IE "Redirection info" was present therein:
2> if the IE "Frequency info" is present, attempt to camp on a suitable cell on the indicated UTRA carrier
included in the RRC CONNECTION RELEASE message;
2> if the IE "GSM target cell info" is present, attempt to camp on a suitable cell of the list of cells for the
indicated RAT included in the RRC CONNECTION RELEASE message. If no cells were indicated for that
