Abstract
A network node includes: a transmission unit configured to register a terminal to a UDR (User Data Repository); a reception unit configured to receive, from the UDR, information for identifying the UDR as a response to registration of the terminal; and a control unit configured to associate the terminal and the information for identifying the UDR with a first time at which the terminal is registered to the UDR to be stored. In a case where an error indication of the UDR is received by the reception unit, the control unit determines whether or not a re-registration of the terminal is needed, based on a time included in the error indication and the first time.
