The LDAP sends the response with search results in the LDAP Search success message to the PCF. |

PCF evaluates the policies to determine the newly added or modified policies, and install the rules as required. The PCF responds with a set of pccRules to the original N7_Create request from the SMF with HTTP status 201. |

The NAP sends a SOAP request for Subscriber Profile Change to the PCF. |

In response to the request, PCF sends a Success response along with the requested subscriber information to NAP. |

After PCF initiates a search request to LDAP, the PCF sends a LDAP Search request to LDAP. |
8 |
The LDAP responds with LDAP_Search success message and the search results to the PCF. |

PCF reevaluates the policies to determine the updated or modified policies, and installs or removes the policy rules as required. The PCF initiates an N7 Notify request to the SMF. |

The SMF acknowledges the request with the N7 Notify response message towards the PCF. |
