The system includes a position coordinate receiving section (80) for obtaining positions from a plurality of user terminals, and a nearby user distributing section (94) for selecting, under the condition that the nearby user distributing section (94) obtains a position of a specified user terminal, one or more of the plurality of user terminals corresponding to the position obtained from the specified user terminal and the positions obtained from the plurality of user terminals and providing the specified user terminal with information on the selected one or more of the plurality of user terminals. ## Claims ### Claim 1 A communication system, comprising: a position obtaining unit that obtains positions from a plurality of user terminals, a user terminal selecting unit that selects, under a condition that the user terminal selecting unit obtains a position of a specified user terminal, one or more of the plurality of user terminals corresponding to the position obtained from the specified user terminal and the positions obtained from the plurality of user terminals, and an information providing unit that provides the specified user terminal with information on the selected one or more of the plurality of user terminals. ### Claim 2 (depends on 1) The communication system according to claim 1, further comprising: a storing unit that stores, under a condition that the position obtaining unit obtains a position, identification information of the user terminal from which the position is obtained in association with an area corresponding to the position, into a storage unit, wherein the user terminal selecting unit obtains, under a condition that the user terminal selecting unit obtains a position of the specified user terminal, the identification information of the user terminal in association with the area corresponding to the position, the identification information being stored in the storage unit. ### Claim 3 (depends on 2) The communication system according to claim 2, wherein, under a condition that the identification information has been stored in the storage unit for more than a predetermined period of time, the storage unit deletes the identification information of the user terminal. ### Claim 4 (depends on 2) The communication system according to claim 2, wherein the user terminal selecting unit includes a unit that obtains identification information of the user terminal, the identification information being stored in the storage unit, in association with an area adjacent to the area corresponding to the position obtained from the specified user terminal. ### Claim 5 (depends on 1) The communication system according to claim 1, further comprising a position display unit that displays a position obtained from the selected one or more of the plurality of user terminal. ### Claim 6 (depends on 1) The communication system according to claim 1 comprising the plurality of user terminals, wherein each of the plurality of user terminals comprises: a calculating unit that repeatedly calculates a position of itself, and store the calculated position repeatedly into a position storage unit; and a transmitting unit that transmits a plurality of calculated positions stored in the position storage unit to a server. ### Claim 7 (depends on 1) The communication system according to claim 1, wherein the information providing unit provides the specified user terminal with data for an application program obtained from the selected user terminal. ### Claim 8 A communication method, comprising: obtaining positions from a plurality of user terminals; selecting, under a condition that a position of a specified user terminal is obtained, one or more of the plurality of user terminals corresponding to the position obtained from the specified user terminal and the positions obtained from the plurality of user terminals; and providing the specified user terminal with information on the selected one or more of the plurality of user terminals. ### Claim 9 A program for causing a computer to execute: obtaining positions from a plurality of user terminals; selecting, under a condition that a position of a specified user terminal is obtained, one or more of the plurality of user terminals corresponding to the position obtained from the specified user terminal and the positions obtained from the plurality of user terminals; and providing the specified user terminal with information on the selected one or more of the plurality of user terminals. ### Claim 10 An information storage medium for storing a program for causing a computer to execute: obtaining positions from a plurality of user terminals; selecting, under a condition that a position of a specified user terminal is obtained, one or more of the plurality of user terminals corresponding to the position obtained from the specified user terminal and the positions obtained from the plurality of user terminals; and providing the specified user terminal with information on the selected one or more of the plurality of user terminals.
