Revision Details

Release

This Behavior Change was introduced in 21.4.14. With this release, CLI support for P-GW to include AVPs in CCR-U messages is also applicable to 21.11.3

21.11.3

This Behavior Change was introduced in 21.4.14. With this release, CLI support for P-GW to include AVPs in CCR-U messages is also applicable to 21.8.10

21.8.10

For Wi-Fi calls, when P-GW receives the AVPs - UDP-SOURCE-PORT and UE-Local-IP-Address, in the CB Rsp or UB Rsp or DB Rsp message, it sends these AVPs in the CCR-U messages towards the PCRF even if there are no changes in the AVP values.

21.4 .14

First introduced.

Pre 21.2

Feature Changes

For Wi-Fi calls, when P-GW receives the AVPs - UDP-SOURCE-PORT and UE-Local-IP-Address, in the CB Rsp or UB Rsp or DB Rsp message, it sends these AVPs in the CCR-U messages towards the PCRF even if there are no changes in the AVP values.

To support the above functionality, a new keyword - ue-ip-udp-port, is added to the diameter encode-supported-features command in the Policy Control Configuration Mode. By default, this keyword is disabled.

Previous Behavior: For Wi-Fi calls, if P-GW receives the AVPs - UDP-SOURCE-PORT and/or UE-Local-IP-Address in the CB Rsp, UB Rsp or DB Rsp, it checks for a change in the AVP values with the value received earlier. If there are no changes in the AVP values, then the P-GW does not send these AVPs in the CCR-U message towards PCRF. Otherwise, the P-GW only sends the UE-Local-IP-Address IE in the CCR-U message towards PCRF.

New Behavior: For Wi-Fi calls, when the CLI is configured with the keyword ue-ip-udp-port enabled, the P-GW sends the AVPs - UDP-SOURCE-PORT and UE-Local-IP-Address in the CCR-U message towards PCRF.


Note

If P-GW does not receive the above mentioned AVPs in the CB Rsp, UB Rsp or DB Rsp message, it does not send the AVPs in the CCR-U message towards PCRF.

Command Changes

diameter encode-supported-features

In the Policy Control Configuration mode, the diameter encode-supported-features command’s netloc-untrusted-wlan is supported with the ue-ip-udp-port keyword which facilitates the P-GW to include the UDP-SOURCE-PORT and UE-Local-IP-Address AVPs in the CCR-U message sent towards PCRF.

To enable this functionality, use the following configuration:

configure 
   context context_name 
      ims-auth-service service_name 
         policy-control 
            diameter encode-supported-features netloc-untrusted-wlan ue-ip-udp-port 
            no diameter encode-supported-features 
            end

NOTES:

  • The ue-ip-udp-port keyword is displayed only if netloc-untrusted-wlan is configured.

  • ue-ip-udp-port : Sends the UDP-SOURCE-PORT and UE-Local-IP-Address AVPs in CCR-U messages for Wi-Fi calls even though the AVP values remain unchanged.

  • no : Disables this functionality at an IMS-Auth service level.

Performance Indicator Changes

show ims-authorization service all verbose

The output of this command includes the following fields in support of this functionality:
