Abstract: Proposed is a network function for UPF management in a mobile communication system. The network function includes a memory configured to store at least one program therein, a transceiver configured to transmit and receive at least one signal, and a processor configured to execute the at least one program stored in the memory, wherein the processor is configured to register at least one UPF on the basis of a network slice, receive a UPF selection-related query message from an SMF, compute a UPF path on the basis of the query message, and forward, to the SMF, a response including the computed UPF path.

Abstract: The present disclosure is related to a device and method for publishing a certificate. The method includes receiving an RPC message including an publishing method from a client; when the client includes request authority, generating a wrapper for each certificate of a bundle and storing the generated wrapper in a database; when the certificate is not a final certificate, initializing a location and counter of a next certificate to be fetched; transmitting a certificate fetching request from the location; when the certificate is a newly fetched certificate, updating the location of the certificate, incrementing a count variable, generating a certificate wrapper for the certificate, and adding the generated certificate wrapper to the database; and when the certificate is reliable, transmitting an RPC response message to the client.
