Static Rule and Predef Rules (Activated over Gx)
Previous Behavior: The matched rule/ billing policy for DCCA buffered packets was validated after getting the quota
response. On receiving the quota response, the packet with the matched rule/ billing policy which no longer exist was
not sent for charging, however it was being sent to post processing and then sent out (without charging).

not sent for charging, however it was being sent to post processing and then sent out (without charging).
New Behavior: After receiving the quota response for the buffered packet, if a mapped static rule/ billing policy no
longer exist, it will not be sent for charging or post processing, and will be dropped.
longer exist, it will not be sent for charging or post processing, and will be dropped.
Maximum Number of group-of-ruledefs Increased
A group-of-ruledef is a logical collection of multiple ruledefs that have a similar charging action.
Previous Behavior: In earlier releases, a maximum of 64 group-of-ruledefs can be configured.
New Behavior: With this release, a maximum of 128 group-of-ruledefs can be configured.
Maximum Number of Rule Lines in a Ruledef Increased
A ruledef is a collection of rule-lines configured on the action-priority line of a rulebase.
Previous Behavior: In earlier releases, a maximum of 10 rule-lines can be configured per ruledef.
New Behavior: With this release, a maximum of 32 rule-lines can be configured per charging, routing, and post-
processing ruledef.

Optimization of Host-pool and Port-Range based rule-lines
Host pools are used to specify a complex set of IP addresses that include unique IP addresses, IP addresses with masks,
or IP address ranges, and are used for rule matching.

Previous Behavior: In earlier releases, the implementation of host-pool based rule-lines is slow with significant
performance impact.

Parse OS-Signature with Tethering Detection Disabled
This release enables os-signatures to be collected from TCP SYN even when tethering detection is disabled from the
rulebase. This is useful to collect os-signatures which can be used to build an OS database for the tethering detection
feature.

feature.
Previous Behavior: The os-signature was parsed only when tethering detection is enabled in rulebase.
New Behavior: Even when tethering detection is disabled, os-signature will be parsed if an EDR/UDR with an os-
signature variable is present in a rulebase, or charging-action in the rulebase.
