PCRF can send any number of Flow-Information AVPs in CC-Answer (CCA) and Re-Auth-Request (RAR) messages. Currently, the ECS supports processing of eight Flow-Information AVPs and remaining, if any, are ignored. With this enhancement, ECS supports up to 16 Flow-Information AVPs and remaining, if any, are ignored.

This section provides a brief overview of how this feature works.

• P-GW initiates Create Bearer Request/Update Bearer Request with TFTs for all 16 Flow-Information AVPs.

• P-GW initiates multiple Create Bearer Request/Update Bearer Request if TFTs for all 16 Flow-Information AVPs cannot be accommodated in a single message.

• Rule match for dynamic rule to consider up to 16 Flow-Information AVPs for traffic classification.

• If more than 16 Flow-Information AVPs are received, only 16 AVPs are processed and remaining AVPs are ignored.

• P-GW checkpoints all 16 Flow-Information AVPs received from PCRF in CCA and RAR messages to standby chassis if standby chassis is on same release.

• P-GW recovers all 16 Flow-Information AVPs after Session Manager recovery.

• CRR/checkpoint size does not increase if P-GW receives less than 8 Flow-Information AVPs.

• P-GW checkpoints up to 8 Flow-Information AVPs to standby chassis if standby chassis is on older release, and if it receives more than 8 Flow-Information AVPs from PCRF in CCA and RAR messages.

• ICSR upgrade from N-1 to N, and ICSR downgrade from N to N-1 release works as expected.

The output of the following CLI commands has been modified to display 16 Flow-Information AVPs:

• show active-charging sessions full all

• show subscribers pgw-only full all
