Publication number: 20120258765Abstract: A base station outputs annunciation information which corresponds to a plurality of radio cells established by a 3G public base station and an LTE public base station and which is different from annunciation information output from the 3G public base station and the LTE public base station into a target region X and forms a radio cell. A mobile station that enters the radio cell receives the annunciation information of the radio cell and executes a position registration process. An information administration device can thereby find the mobile station based on the position registration process even in the environment where a plurality of radio cells to which different frequencies are assigned are established geographically overlapping with one another.Type: ApplicationFiled: December 9, 2010Publication date: October 11, 2012Applicant: NTT DOCOMO ,INC.Inventors: Takeshi Okamoto, Hiroyuki Hosono, Takeshi Terayama, Takaaki Sato

Patent number: 8275133Abstract: When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover.Type: GrantFiled: March 30, 2006Date of Patent: September 25, 2012Assignee: NTT Docomo, Inc.Inventors: Motoshi Tamura, Mutsumaru Miki, Akiko Okamoto, Kenya Kusunose, Akihiro Uchikoshi, Daisuke Igarashi, Katsuhiko Yamagata, Takaaki Sato, Junichiro Hagiwara, Yasuyuki Watanabe, Takuya Hamajima, Masafumi Hata, Nobutaka Ishikawa, Yoshiyuki Yasuda, Kazufumi Yunoki, Nobuhide Uchiyama

Patent number: 8229429Abstract: In a position registering method, a radio control station (RNC) transmits report information including a first position number, which has been extracted by using a cell identifier as key information, to the cell identified by the cell identifier. A mobile station (UE) transmits a position registration request when the first position number included in the report information is different from a position number stored in the mobile station. The radio control station (RNC) notifies the first position number and the second position number, which have been extracted by using as the key information the cell identifier for identifying the requester of the position registration request, and a user identifier for identifying the mobile station. An exchange (MSC/SGSN) stores the notified user identifier, first position number, and second position number in association with one another.Type: GrantFiled: April 8, 2009Date of Patent: July 24, 2012Assignee: NTT DoCoMo, Inc.Inventors: Masafumi Masuda, Takaaki Sato

Patent number: 7959816Abstract: The wet-processing apparatus includes a wet-step bath in which a wet-step is carried out, and a vibration-type film separator for separating impurities out of a solution used in the wet-step. The wet-processing apparatus further includes a re-supply path through which the solution out of which the impurities were removed by means of the vibration-type film separator is re-supplied to the wet-step bath. Thus, it is possible to reuse a solution and a material of which a pattern is composed. Since the vibration-type film separator is used, it is possible to reduce a frequency of exchanging filters equipped in the vibration-type film separator, and ensure a high rate at which a material of which a pattern is composed is recovered, regardless of a specific gravity of the material.Type: GrantFiled: May 26, 2006Date of Patent: June 14, 2011Assignee: Panasonic CorporationInventor: Takaaki Sato

Patent number: RE43296Abstract: A branch candidate selecting method by a mobile station and a diversity handover control method on a network side in DHO performance are provided which consider a maximum cable branch number and maximum radio branch number of the mobile station, when the mobile station detects the plurality of addition branch candidates and deletion branch candidates. The mobile station inserts a plurality of addition branch candidates and deletion branch candidates, that is, all the DHO candidates into one handover trigger signal, and notifies the network. The addition branch candidates are put into addition information parameters in the handover trigger signal, and the deletion branch candidates are put into deletion information parameters. To simplify processing on the network side, the network side separates the addition branch candidates from the deletion branch candidates, and carries out sequential processing of them independently.Type: GrantFiled: October 1, 2009Date of Patent: April 3, 2012Assignee: NTT DoCoMo, Inc.Inventors: Tomoyuki Ohtani, Motoshi Tamura, Takaaki Sato
