connection. The PCF and the PDSN maintain an association of the MS‟s IMSI address 1
and MN Session Reference ID with the A10 connection. 2
When establishing a new A10 connection, the PCF shall include the ANID NVSE with 3
the Current Access Network Identifiers (CANID) as specified in [13]. If the PCF received 4
the ANID from the BS, it shall populate it in the PANID field of the ANID NVSE sent in 5
the A11-Registration Request message. 6
If the PCF is able to determine that the setup of the A10 connection is due to a dormant 7
handoff or an inter-PCF hard handoff (e.g., the A9-Setup-A8 message included the 8
Access Network Identifiers (ANID) IE or the Data Ready Indicator field in the A9 9
Indicators IE was set to „0‟), the PCF shall include the Mobility Event Indicator (MEI) 10
CVSE in the A11-Registration Request message. The PCF may provide the PDSN with 11
an indication of PCF enabled features for the A10 connection (e.g. short data indication). 12
In a fast handoff, the (target) PCF shall set the flag bit S to „1‟, include the Anchor P-P 13
Address and set the Lifetime value to T
presetup
in the A11-Registration Request message. 14
In other cases the PCF shall set the Lifetime to T
rp.

2.1.1.2 Successful Refresh Operation 16
All A11-Registration Request messages with a non-zero Lifetime value sent for an 17
existing A10 connection have the effect of requesting a refresh of that A10 connection. 18
When sending an A11-Registration Request message for an already existing A10 19
connection, the PCF shall use the same Key value (refer to the Session Specific 20
Extension in section 4.2.12). 21
If the A9-Setup-A8 message does not contain a handoff indication, then the PCF 22
shall send an A11-Registration Request message to the PDSN upon receiving the 23
A9-Setup-A8 message. 24
In a fast handoff, the (target) PCF shall send an A11-Registration Request message 25
to the PDSN upon receiving the A9-Setup-A8 message. 26
In all other handoff situations, the (target) PCF shall send an A11-Registration 27
Request message to the PDSN to initiate setup of the A10 connection when the 28
(target) BS captures the MS (i.e., upon receiving an A9-AL Connected message from 29
the BS). 30
If the PCF is able to determine that an inter-PCF hard handoff has occurred (e.g., the A9-31
Setup-A8 message included the Access Network Identifiers (ANID) IE or the Data Ready 32
Indicator field in the A9 Indicators IE is set to „0‟), the PCF shall include the MEI CVSE 33
and the ANID NVSE in the A11-Registration Request message. 34
In a fast handoff case the Lifetime value shall be set to T
presetup
; in all other cases the 35
Lifetime value shall be set to T
rp
. 36
If the PCF set the Lifetime value to T
presetup
in the A11-Registration Request message 37
(i.e., in the case of a fast handoff), then the PCF shall not refresh the A10 connection 38
unless it is notified that the MS has successfully accessed the target BS. At that time, the 39
PCF refreshes the A10 connection with the PDSN by sending an A11-Registration 40
Request message with Lifetime value set to T
rp
. 41
If the PCF set the Lifetime value to T
rp
, then the PCF periodically refreshes the A10 42
connection with the PDSN by sending an A11-Registration Request message with a non-43
