wherein the service request includes a parameter indicating a client type that one or more candidate target NFs can serve, and wherein the service response includes information of at least one NF instance of a target NF when the target NF matching the service request can be found or includes information of at least one other NF instance not dedicatedly serving the client type when the target NF matching the service request cannot be found.
