Abstract
A method of managing an Evolved Packet System (EPS) fallback procedure in a 5GS network. The method comprises making available to the Access Mobility Function (AMF), a configuration parameter per Public Land Mobile Network (PLMN) indicating if early or late PCRF/PCF interaction with the IMS is used. Then, upon receipt by the network of a 5GS network registration request from a UE, the home PLMN of the UE is identified as is the configuration parameter for that PLMN. The identified parameter is then used to determine for the UE whether or not EPS fallback is available to the UE, and an indication of the determination is sent to the UE.
