Feature Changes

Currently, APN AMBR is included in the Create Session Response even if it is not modified by the PCRF. This feature has been implemented to comply to the 3GPP specifications. With this feature, now APN AMBR will be included on the S5/S8, S4/S11, and S2a/S2b interfaces if the received APN-AMBR has been modified by the PCRF.

Previous Behavior: APN AMBR was included in Create Session Response even if it was not modified by the PCRF.

New Behavior: Now, APN AMBR will be included on the S5/S8, S4/S11, and S2a/S2b interfaces if the received APN-AMBR has been modified by the PCRF. A new CLI command has been added to enable/disable inclusion of the APN-AMBR value in the Create Session Response for the modified value received by the PCRF.


Important

P-GW supports APN-AMBR value upto 4294967 kbps.

Command Changes

egtp

Two new keywords have been added to the egtp command to enable/disable inclusion of APN-AMBR value in Create Session Response for modified value received by PCRF. 


configure  
   context  context_name 
      pgw service  service_name 
         [ default | no ] egtp create-session-rsp apn-ambr-always-include  
         end
Notes:

  • default: APN AMBR is not included in the CS Response if APN AMBR is not received from the PCRF. P-GW supports APN-AMBR value upto 4294967 kbps.

  • no: Does not include APN AMBR in the CS Response. This is the default behavior.

  • create-session-rsp: Provides an option to include APN-AMBR in the Create Session Response

  • apn-ambr-always-include: Always includes APN-AMBR IE in Create Session Response.
