CSCup86339 - Assert sessmgr_ipv4.c:10235 :

sessmgr_ipv4_process_user_pkt_part2()

Applicable Products: GGSN, P-GW

Feature Changes

Processing of Data Packets in S2b Handoff for Dormant Bearer

Previous Behavior: During S2b handoff, DCCA was trying to send the bufferred data packets to session manager even
for a dormant bearer. Such dormant bearer existed only at ECS and not at session manager, and thereby resulting in
system crash.

New Behavior: With the current implementation, after OCS response is received, it is verified to determine if the
bearer is in dormant state at ECS. If the bearer is found to be in dormant state, then such buffered packets will be
dropped.

CSCuq23706 - Removal of dynamic Rule is not working in UE only mode

Applicable Products: GGSN, P-GW

Feature Changes

Processing of Rule Removal

Previous Behavior: Removal of PCEF rules failed in the UE-only mode.

New Behavior: Rule removal will be accepted in UE-only mode for EPS IP-CAN bearer.

This generic behavior is per the standards and presently customers are using custom based CLIs for GnGp use cases.

Customer Impact: Some functionalities for GnGp handover which were not working previously will work now. For
example, GnGp handover cases having default bearer with charging rules will work seamlessly in both UE-only and
mixed modes.
