Previous Behavior: A call was associated with local policy only when the call was of type emergency or when a
failure was detected in the PCRF connection and local-fallback was configured as failure-handling action. At a time, the
call was associated with either PCRF or local-policy.
failure was detected in the PCRF connection and local-fallback was configured as failure-handling action. At a time, the
call was associated with either PCRF or local-policy.
New Behavior: In this release, the calls can be associated with both PCRF and local-policy simultaneously. If the
PCRF does not support an event-trigger, local-policy will be contacted (qos-change and default-eps-bearer-qos are
supported).
PCRF does not support an event-trigger, local-policy will be contacted (qos-change and default-eps-bearer-qos are
supported).
Local-policy can be used to support dual-mode to provide the load balancing support for PCRF. Local-policy can also
be used for providing the failure-handling support when PCRF is down or any failure is detected.
be used for providing the failure-handling support when PCRF is down or any failure is detected.
Customer Impact: This enhancement helps in reducing the traffic between the P-GW and PCRF and does not
compromise on the use case the operator wants to apply. By sharing the load of PCRF with P-GW, PCRF can handle
more number of new calls and thus improving the overall performance of the network.
