Patent number: 10831515Abstract: A user's proficiency level of operation of a user apparatus is determined with higher accuracy. Acquisition unit acquires service contract information of a user using the apparatus. Determination unit determines the user's proficiency level of operation of the user apparatus based on service contract information acquired by acquisition unit. Trigger determination unit determines whether or not there has been an event (called a “trigger”) that triggers display of a hint to the user using the apparatus. If it is determined by trigger determination unit that a trigger has occurred, display control unit displays, on a display means, a hint corresponding to the trigger and the proficiency level determined by determination unit.Type: GrantFiled: April 18, 2017Date of Patent: November 10, 2020Assignee: NIT DOCOMO, INC.Inventors: Nozomi Matsumoto, Motoya Takahashi, Sumin Kwak, Tomoya Okumura, Yuuki Fukuyoshi

Patent number: 10009828Abstract: The present invention is designed so that, when a plurality of inter-terminal discovery signals with varying numbers of information bits are used in a radio communication system in which inter-terminal communication is carried out, user terminals can be discovered based on the inter-terminal discovery signals. According to the inter-terminal communication method of the present invention, a user terminal (#1) determines the signal format of a discovery signal based on the number of information bits of the discovery signal, transmits the discovery signal based on the signal format, and also transmits signal format information to represent this signal format. A user terminal (#2) receives the signal format information from the user terminal (#1), and, based on the signal format represented by the signal format information, detects the discovery signal.Type: GrantFiled: October 16, 2014Date of Patent: June 26, 2018Assignee: NIT DOCOMO, INC.Inventors: Hiroki Harada, Yongbo Zeng, Qun Zhao, Yongsheng Zhang

Patent number: 9946453Abstract: A display device calculates an operation amount of a user's input operation based on a detected indicated position. Display device displays component images on display surface based on the operation amount calculated. If display device determines that the indicated position is no longer detected, display device determines whether the calculated operation amount is smaller than or equal to a threshold. If it is determined that the calculated operation amount exceeds the threshold, display device executes an acquiring operation of a newly arrived email.Type: GrantFiled: April 3, 2013Date of Patent: April 17, 2018Assignee: NIT DOCOMO, INC.Inventors: Naoyuki Nakao, Hitoshi Obata

Patent number: 9882694Abstract: In order to enable notification of radio resources that make up an enhanced downlink control channel, a radio base station that transmits downlink control information for a user terminal using an enhanced downlink control channel frequency-division-multiplexed with a downlink shared data channel is provided. The radio base station includes a configuring section that configures the user terminal with a resource set including a plurality of resource blocks allocated to the enhanced downlink control channel; and a notifying section that notify the user terminal of pattern information of the resource blocks that make up the resource set and information indicating a number (n) of resource blocks that make up the resource set.Type: GrantFiled: October 28, 2013Date of Patent: January 30, 2018Assignee: NIT DOCOMO, INC.Inventors: Kazuaki Takeda, Qin Mu, Liu Liu, Lan Chen

Patent number: 9084182Abstract: When a network is in a state of requiring some sort of access barring, a reference value notified to a mobile device is determined to indicate a value in which an access of a certain mobile device is denied while an access of another mobile device is allowed. When an own device has a special type access class, it is determined that an access is allowed The appropriateness of an access is determined according to designation from the network when the own device has the special type access class, and when the own device does not have the special type access class, it is determined that an access is denied.Type: GrantFiled: December 20, 2011Date of Patent: July 14, 2015Assignee: NIT DOCOMO, INC.Inventors: Mikio Iwamura, Minami Ishii, Mutsumi Ishimoto

Patent number: 7031695Abstract: A portable terminal 10 according to the present invention is provided with a request acquiring means, a verifying means, and an output means. The request acquiring means acquires an access right authentication request from a display application 153 to a telephone directory management application 152 managing telephone directory data stored in a telephone directory database 151, along with application authentication information held by the display application 153. The verifying means determines the validity of the application authentication information in accordance with the access right authentication request. When it is determined that the application authentication information is valid, the output means permits the access right authentication request and outputs the telephone directory data to the display application 153 in accordance with an access request to the telephone directory data.Type: GrantFiled: April 23, 2003Date of Patent: April 18, 2006Assignee: NIT DoCoMo, Inc.Inventors: Hiroshi Aono, Kazuhiko Ishii, Kensaku Mori, Sadayuki Hongo

Patent number: 6697622Abstract: A control method of searching for a neighboring cell of a mobile station communicating with a base station is provided in a direct sequence CDMA mobile communication system which transmits information by carrying out double modulation using a first spreading code group and a second spreading code. The first spreading code group includes spreading codes that have a same repetition period as an information symbol period and are used in common by the base stations, and the second spreading code has a repetition period longer than the information symbol period. The base stations are assigned different second spreading codes.Type: GrantFiled: September 5, 2000Date of Patent: February 24, 2004Assignee: NIT DoCoMo, Inc.Inventors: Yoshihiro Ishikawa, Seizo Onoe, Kazufumi Yunoki, Akihiro Higashi
