摘要
The present invention relates to a method for opening an IMS-based service in a 5G network and a system using the same. The method according to the present invention comprises the steps of receiving a Diameter AAR message from an AF, to select a PCF to process a policy for a data session with the BSF. Transmitting an Nbsf_Management_Discovery request message, receiving an Nbsf_Management_Discovery response message including the selected PCF information from the BSF, converting the Diameter AAR message received from the AF into an Npcf_PolicyAuthorization_Create request message, and transmitting the converted Npcf_PolicyAuthorization_Create request message to the selected PCF step, receiving the Npcf_PolicyAuthorization_Create response message delivered in response to the Npcf_PolicyAuthorization_Create request message from the PCF, converting the Npcf_PolicyAuthorization_Create response message received from the selected PCF into a Diameter AAA message, and delivering the converted Diameter AAA message to the AF includes steps.
