Patent number: 9237508Abstract: A mobile terminal capable of determining whether a near field communication source is a mobile terminal or not, and capable of appropriately restricting information reading in near field communication. The mobile terminal includes an antenna for near field communication and an RF part. The RF part includes an electromotive force measuring part which measures the electromotive force of a carrier wave received by the antenna, a communication permission/prohibition determining part which, when the measured electromotive force is less than or equal to a predetermined threshold value, determines that the sender of the carrier wave is a mobile terminal and outputs a communication prohibition signal, and an RF controller which acquires the communication prohibition signal and locks the RF part.Type: GrantFiled: February 18, 2013Date of Patent: January 12, 2016Assignee: NTT DOCOMO, INC.Inventors: Kumiko Yamaguchi, Tetsuhiro Tanno, Kunio Yoshikawa, Tomohiro Akiyama, Tetsuhiro Sasagawa

Patent number: 9027160Abstract: A secure element (SE) unit 102 holding service data used by an application is provided in a UIM card 100. Thus, when the user identify module (UIM) card 100 is transferred between portable terminals, service data and accompanying information of the application can be moved together with the UIM card 100 to another portable terminal. In addition, an access management unit 400 included in a portable terminal 200 compares UIM information of a UIM information storage unit 103 with UIM information, held by an authority information holding unit 205, of a UIM card of which use authority is possessed by an application. If they do not agree, access to service data stored in the SE unit 102 is restricted.Type: GrantFiled: July 7, 2010Date of Patent: May 5, 2015Assignee: NTT DOCOMO, Inc.Inventors: Kumiko Yamaguchi, Masaharu Nakatsuchi, Tetsuhiro Tanno, Mao Asai, Ryo Nakajima

Publication number: 20140054376Abstract: A portable terminal that can centrally determine payment priorities for all services in a portable terminal is provided. This portable terminal 10 has a total of two or more secure elements (referred to below as SEs) in either of both of a removable media and the portable terminal. The portable terminal 10 includes a base-band section 14 having a card search section 14a that searches the removable media connected to the portable terminal 10, a priority storing section 14b that stores priorities that centrally control all services in the two or more SEs, an optimum priority generation section 14c that excludes the priorities of the services in the removable media that are not searched for from the stored priorities, rearranges the priories of services that are not excluded from highest to lowest, and generates the rearranged priorities as optimum priorities, and a radio frequency section 12 having an optimum priority storing section 12a that stores the generated optimum priorities.Type: ApplicationFiled: September 25, 2012Publication date: February 27, 2014Applicant: NTT DOCOMO, INC.Inventors: Kumiko Yamaguchi, Kunio Yoshikawa, Tomohiro Akiyama, Tetsuhiro Tanno, Tetsuhiro Sasagawa

Patent number: 8239324Abstract: A mobile terminal capable of causing the user side to grasp whether or not a credit settlement service stops with a simple operation is provided. In the mobile terminal 10, validation and invalidation of a storage area within an IC chip assigned to an issuer application corresponding to one issuer are switched based on switching instruction information received from an issuer terminal 20 managed by one issuer. Then, when the issuer application starts, there is displayed in a lump whether or not the respective issuer applications are available on a display part 16, based on state information indicating whether or not the respective storage areas are validated. Therefore, in the mobile terminal 10, even if plural issuer applications are stored, it is possible to cause the user side to grasp which kind of the credit settlement service stops, with a simple operation of only starting a management application.Type: GrantFiled: March 6, 2008Date of Patent: August 7, 2012Assignee: NTT DoCoMo.
