21.20.11

The StarOS 21.15.52 is enhanced with IPv4/IPv6 address encoding change in Flow-Description AVP under Application-Detection-Information AVP for APPLICATION-START event trigger from P-GW.

21.15.52

Feature Changes

Previous Behavior: In CCR-U for APPLICATION-START event trigger from P-GW, Flow-Description AVP under Application-Detection-Information AVP towards PCRF was encoded as:

  • For ipv4 flows a netmask of /0 was used

  • For ipv6 flows prefix length of 0 was used

New Behavior: In the release 21.15.52, in CCR-U for APPLICATION-START event trigger from P-GW, Flow-Description AVP under Application-Detection-Information AVP towards PCRF is encoded as:

  • For ipv4 flows a netmask of /32 is used

  • For ipv6 flows prefix length of 128 is used

Customer Impact: PCRF receives flow description value with 32/128 netmask/prefix. If PCRF rejects the value, ADC over Gx will not work.
