摘要:
An object of the present invention is to provide a cell phone capable of using base station position information and GPS position information more appropriately. This cell phone 10 is provided with a first position acquirer 12 for acquiring first position information of cell phone 10 calculated using a position of at least one base station under which the cell phone 10 is placed, a second position acquirer 13 for acquiring second position information of cell phone 10, using the global positioning system, an accuracy comparator 14 for making a comparison between respective accuracies of the first position information and the second position information, and a position information using part 15 for selectively using the first position information or the second position information in accordance with the result of the comparison; the position information using part 15 first uses the first position information, irrespective of the result of the comparison made by the accuracy comparator 14, and thereafter uses position information with higher accuracy out of the first position information and the second position information in accordance with the result of the comparison made by the accuracy comparator 14.
摘要:
A positional information service server selects a measuring system most suitable for measuring quality conditions received from a terminal requesting measurement when able to measure position of a designated mobile unit to be measured by a plurality of measuring systems. The positional information service server acquires the positional information of the mobile unit based on the selected measuring system, and transmits it to the terminal designated as the one to be notified.

摘要:
Each time mobile communication terminal 10 moves a distance of 150 kilometers, it computes its approximate position by performing a stand-alone position measurement, and stores the approximate position. When mobile communication terminal 10 needs to precisely measure its location it notifies position measurement assist server 30 of the stored approximate position, to thereby perform a GPS position measurement operation by using satellite capturing data transmitted, accordingly, from position measurement assist server 30.
摘要:
Location information providing unit of gateway server 40 obtains location information on cellular telephone 10, 20 and 30 each produced in different expression format from measuring center 50, converts obtained location information into expression formats which IP server 80A and IP server 80B can deal with via location information converting device 60, and notifies converted location information to IP server 80A and 80B. As a result, IP server 80A and 80B can obtain location information on each cellular telephone 10, 20, and 30 without experiencing any difficulty.
摘要:
A measuring device, with a display mode able to display separately map elements specified by a user selected from a list of map elements existing within the error span of the measured distance of a location by the help of which, the user can determine his/her own location and correct the measured distance of the location.

A Web access providing system that allows a user to access a Web page as if he or she is making a telephone call. When a user terminal B sends out a service request S1 and an originating connection request S12, a connection notification S4 is sent to a user terminal A through local Mobile multimedia switching system (L-MMS 1) and a gateway mobile multimedia switching system (G-MMS 2). When receiving the connection notification 4, the user terminal A performs authentication. The authentication verifies whether the telephone number of the user terminal B is contained in a telephone directory of the user terminal A. After the authentication, the user terminal A outputs a connection communication response S5 to the G-MMS 2. The connection communication response S5 contains the URL of a Web page associated with the user terminal A. The L-MMS 1 receives the URL and outputs a connection request S7. Thus, the user terminal B can access and browse the Web page implemented by a Web server 3.
摘要:
Menu data supplied from an IP server 500 to a mobile station 101 is embedded with a location information substitution data string “NULLAREA” together with a URL of a particular IP server 500. The mobile station 101, upon detection of the location information substitution data string from a menu data selected by the user, determines whether location information can be transmitted to the IP server 500. In the case where the determination is that the transmission is permitted, the mobile station 101 detects its location information and, after substituting the location information for the location information substitution data string, transmits the data to the IP server 500.
摘要:
Research server 4 transmits to moving status search server 3 a request for providing moving status information containing a conditional expression, designating attributes of users to be researched. Moving status search server 3 extracts users having user attribute information (information such as address, occupation or the like, of each user) matching the conditional expression and obtains location information from mobile stations 1 which the users possess. In this way, moving status search server 3 generates moving status information on the basis of location information of users having user attribute information matching the conditional expression, and transmits the generated moving status information to research server 4.
