3> if a new security key set was received for this CN domain but was not used either for integrity protection
or ciphering during this RRC connection:
4> set the START value for this domain to zero; and
4> store this START value for this domain in the volatile memory of the ME
3> else:
4> if the current "START" value, according to subclause 8.5.9 for this CN domain, is greater than or
equal to the value "THRESHOLD" of the variable START_THRESHOLD:
5> delete the Kc key for this CN domain;
5> delete the ciphering and integrity keys that are stored in the UE for that CN domain;
5> set the "START" values for this CN domain to zero and store it the volatile memory of the ME;
5> inform the deletion of the key to upper layers.
4> else:
5> store the current "START" value for this CN domain in the volatile memory of the ME.
NOTE:
Prior to storing the "START" value, the UE should calculate this "START" value according to subclause
8.5.9.
1> if the UE supports RAN-assisted WLAN interworking:
2> if timer T330 is not configured:
3> clear the variable WLAN_OFFLOAD_INFO;
3> use the information stored in the variable SYSTEM_INFO_WLAN_OFFLOAD_INFO as specified in
[4], and forward it to upper layers.
2> else:
3> if timer T330 is not running:
4> start the timer T330;
4> use the information stored in the variable WLAN_OFFLOAD_INFO as specified in [4], and forward
it to upper layers.
8.5.3 Open loop power control upon establishment of DPCCH
This procedure is used in FDD mode only.
When establishing the first DPCCH in CELL_DCH the UE shall start the UL inner loop power control at a power level
according to:
Where
1> DPCCH_Initial_power = DPCCH_Power_offset – CPICH_RSCP
DPCCH_Power_offset shall have the value of IE "DPCCH Power offset" in IE "Uplink DPCH power control
info"
The value for the CPICH_RSCP shall be measured by the UE.
When establishing the DPCCH in CELL_FACH state or Idle mode the UE shall start the UL inner loop power control
at a power level according to:
Where
1> DPCCH_Initial_power = P preamble + "Power offset Pp-e"
