If usage monitoring is enabled, and based on operator's policies, the PCF checks if the BSF has already existing PCF serving the combination of SUPI, S-NSSAI, DNN. If no such PCF is found the PCF registers itself to the BSF. Else if an existing PCF is found for the above combination, the PCF returns to the SMF the PCF ID of the existing PCF and a redirection indication. When the SMF receives the PCF ID from the PCF for the the DNN and S-NSSAI of the PDU session, the SMF terminates the current SM Policy Control association and reselects a PCF based on the received PCF ID. The SMF then establishes an SM Policy Control association with that PCF. This CR describes the behavior of the PCF after it has been selected by the SMF and before it registers itself in the BSF. A corresponding 23.501 CR (S2-1905329 and its revision(s)) describes the behavior of the SMF as per the description above.","secretary_remarks":"Revision of S2-1905911.
