September 9, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Suzuki, Toshihiro (Yokohama, JP); Okajima, Ichiro (Yokosuka, JP); Kawakami, Hiroshi (Yokosuka, JP); Jo, Manhee (Yokohama, JP); Ochi, Daisuke (Yokosuka, JP); Nagata, Tomohiro (Tokyo, JP); Kobayashi, Motonari (Yokohama, JP); Oyabu, Yuki (Zushi, JP), filed on March 23, 2010, was published online on August 26, 2014.

The patent's assignee for patent number 8818414 is NTT DoCoMo, Inc. (Tokyo, JP).

News editors obtained the following quote from the background information supplied by the inventors: "A method for collecting location information is specified in the 3GPP, for example, where upon receiving a request from an external server to collect location information of each mobile station, a management server of a carrier operator outputs, in accordance with the request, an instruction to collect the location information of each mobile station to a exchanger (for example, a mobile multimedia switching system (MMS)/a serving/gateway general packet radio service support node (xGSN) and a radio network controller (RNC)) and each node and the controller perform processing to collect the location information. This processing sequence is specified in the 3rd generation partnership project (3GPP) as a mobile terminated-location request (MT-LR) method and is described in Non Patent Literature 1, the 3rd generation partnership project (3GPP) TS23.271, for example."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "Technical Problem

"In a technology described in Non Patent Literature 1, however, a positioning request is made to all specified mobile stations and it is difficult to collect location information of any part of the users. That is, each user needs to be specified to perform processing of a location information request, which causes a lot of trouble to a location information collecting side.

"Therefore, the present invention aims to provide a mobile station, a communication system, and a communication method that are capable of efficiently collecting location information of any user.

"Solution to Problem

"In order to solve the problems described above, a mobile station of the present invention includes: attribute information storage means for storing attribute information; receiving means for receiving a positioning request including attribute information from an external center; determining means for determining, based on the positioning request received by the receiving means and the attribute information stored in the attribute information storage means, whether measurements of the location are necessary or not; positioning means for performing measurements of the location when the determining means determines that measurements of the location are necessary; and notifying means for notifying of location information measured by the positioning means.

"In another aspect, a communication method of the present invention includes: a receiving step of receiving a positioning request including attribute information from an external center; a determining step of determining, based on the positioning request received at the receiving step and attribute information stored in attribute information storage means, whether measurements of the location are necessary or not; a positioning step of performing measurements of the location when it is determined at the determining step that measurements of the location are necessary; and a notifying step of notifying of location information measured at the positioning step.

"According to the invention, the positioning request including attribute information is received from the external center and based on the received positioning request and the attribute information previously stored, it is determined whether measurements of the location are necessary or not. Then, when it is determined that measurements of the location are necessary, measurements of the location are performed and the location information thus measured is notified. Accordingly, it is possible to collect the location information of the mobile station that agrees with an attribute that the management center desires and therefore, it is possible to provide an attentive service and the like based on the location information. For example, when the attribute information is set to the twenties, and an attribute specifying information is set to male, it is possible to grasp a mobile history and the like of the mobile station that agrees with such an attribute. Accordingly, such a mobile history can be used to facilitate store development and the like.

"Furthermore, the mobile station of the present invention may further include positioning area storage means for storing a positioning time period or a positioning area, the positioning means preferably performs measurements of the location on a condition that it is determined by the determining means that the mobile station is being located in the positioning area stored in the positioning area storage means or that a current time is included in the time period stored in the positioning area storage means.

"According to the invention, measurements of the location are performed on the condition that it is determined to be located in the positioning area or included in the time period that are stored and therefore, it is possible to collect location information for more detailed analysis. For example, it is possible to easily grasp the number of people whose attribute information is set to male and being located in a given positioning area.

"Furthermore, in the mobile station of the present invention, the attribute information stored in the attribute information storage means preferably includes user attribute information representing a user attribute.

"According to the invention, the attribute information is the information representing the user attribute and therefore, it is possible to efficiently collect location information focusing on the user attribute. For example, it is possible to collect location information depending on a gender.

"Furthermore, in the mobile station of the present invention, the attribute information stored in the attribute information storage means preferably includes activity state information representing a user activity.

"According to the invention, the attribute information is the activity state information representing the user activity and therefore, it is possible to efficiently collect location information focusing on a state of the user activity. For example, it is possible to collect location information of a user who is moving in high-speed with a car and the like.

"Furthermore, in the mobile station of the present invention, the attribute information stored in the attribute information storage means preferably includes usage state information representing a usage state of a terminal by a user.

"According to the invention, the attribute information is the usage state information representing a usage state of the terminal by the user and therefore, it is possible to efficiently collect location information focusing on the usage state of the terminal by the user. For example, it is possible to collect location information of a user who uses a given application.

"In another aspect, a communication system of the present invention includes the mobile station mentioned above and a location information storage apparatus for storing location information transmitted from the mobile station.

"Thereby, it is possible to grasp the location information in the mobile station, to perform statistical processing etc., on the grasped location information and to provide data obtained by statistical processing outside.

"Advantageous Effects of Invention

"According to the present invention, it is possible to collect location information of the mobile station that agrees with an attribute that the management center desires and provision of an attentive service based on the location information and the like becomes possible. For example, when the attribute information is set to the twenties, and the attribute specifying information is set to male, it is possible to grasp a mobile history and the like of the mobile station that agrees with such an attribute. Accordingly, such a mobile history can be used to facilitate store development and the like."
