Publication number: 20120054157Abstract: There are provided a database apparatus for maintaining a consistency with another database apparatus having a different database key from a database key of the database apparatus, a database consistency system, and a database consistency method. A data collating unit in HLR collates data stored in a database of HLR and data stored in EIR with respect to “telephone number” and “terminal equipment number”. When it is determined by collating that there is an inconsistency between the data, a data deleting unit deletes such inconsistent data, a data collecting unit collects mobile station information from MS. A database updating unit updates the database by use of the collected mobile station information. A collected data notifying unit notifies the collected mobile station information to EIR.Type: ApplicationFiled: May 14, 2010Publication date: March 1, 2012Applicant: NTT DOCOMO, INC.Inventors: Kenichi Fukasawa, Wataru Sakurai, Shigeru Iwashina, Daisuke Akiyama
