The method for (i), includes the steps of: (i-1) pre-provisioning of UDM instance discovery information/parameters to the UE/USIM, (i-2) sending the UDM instance discovery related parameters to a core network element, and (i-3) discovering the right UDM instance at the core network element based on the discovery parameters and related routing information either at the UDM consumer/NRF. The method for (ii) includes the steps of: (ii-1) Secured choice of parameter for UDM instance discovery (e.g. UDM instance identifier) to the core network element and (ii-2) the secured UDM instance identifier generation and management at the UDM to prevent attack on UDM instances. Also a method to identify the cleartext IMSI/SUPI is provided for the re-authentication scenario along with the relevant procedures."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method to select the right UDM instance and ensure the UDM instance security","description":"Methods for (i) finding/discovering the right UDM instances and (ii) ensuring the UDM instance security are provided.
