Feature Description
In the policy-based network, the SPR/LDAP initiates a NAP notification towards PCF to signify a profile change. Upon receiving the notification, the PCF refreshes the subscriber profile by requerying LDAP to receive information about the modified subscriber.
If the NAP endpoint terminates on PCRF, the PCRF forwards the NAP request to PCF when it does not find the session in the local database. In situations where the NAP endpoint terminates on PCF, the PCF requeries LDAP and CHF to refresh the subscriber details.
