CSCum91142 - PGW rejecting the rule modified by PCRF with QOS_Validation
failure
Applicable Products: P-GW
Feature Changes
Previous Rule Processing
Previous Behavior: P-GW was rejecting rules due to QoS Validation failure, although nothing was incorrect about the
rule installed. The rule was still being retained although the rule was rejected and reported. This caused failures and
session manager crashes.
rule installed. The rule was still being retained although the rule was rejected and reported. This caused failures and
session manager crashes.
New Behavior: P-GW now buffers and processes the rule once it recieves response for the previous rule request.
Customer Impact: Rule rejection will not be seen in case the previous rule operation is pending access side updates.
CSCun25302 - Rule failure handling: simultaneous change of eval prec & rule
content
Applicable Products: P-GW
Feature Changes
Rule Failure Handling
Previous Behavior: In a scenario where two dynamic rules (R1 and R2) were installed on one bearer and when a RAR
containing modifications to both the rules was received, the content for rule R1 was modified causing a change in the
evaluation precedence value of R2. When the modification of R2 (as received in RAR) was processed, PCEF used to
send rule failure report to PCRF. However, the rule R2 was not removed from the bearer.

New Behavior: With this enhancement, in this scenario, the dynamic rule R2 will be removed from the bearer.
