    Description


    [0001] The present invention relates to information processing devices, mobile terminals, communication systems, communication methods, and programs that serve to process information.

    [0002] Some of mobile terminals that have been released in recent years have a near field communication function using a technique such as infrared or Bluetooth besides a radio communication function for speech communication and transmission and reception for electronic mail.

    [0003] For these mobile terminals, a technique that exchanges information between mobile terminals that are approaching to each other using the near field communication function has been developed (for example, refer to JP 2007-142613 A (Patent Literature 1)). For example, a technique that, when users who graduated from the same school are approaching to each other, causes mobile terminals that the users carry respectively to perform the near field communication could be contemplated.

    [0004] In the foregoing technique, a condition of whether one mobile terminal performs the near field communication with another one is unconditionally set up based on user information about the users to which these mobile terminals belong. Thus, a problem will arise in which a condition, that is based on the locations of mobile terminals, cannot be flexibly arranged. For example, if users who graduated from the same metropolitan high school are in the Metropolitan Area, the likelihood is that they will pass by each other. In contrast, if they are in Hokkaido, Japan, it is not likely that they would pass by each other.

    [0005] Document US 2009/012953 A1 (CHU JOHN [US] ET AL) is directed to a solution determining, for a user of a first mobile terminal, points of interest (POIs) and personal contacts (users of other mobile terminals using the same solution) satisfying a condition. The determination is based on the current location of the mobile terminals and the distance to the home location of the user of the first terminal.

    [0006] The scope of the invention is defined by the appended independent claim 1. Further embodiments are defined in the respective dependent claim. Embodiments which do not fall within the scope of the appended set of claims are to be interpreted as background information, useful only for understanding the invention.

    [0007] Next, with reference to the accompanying drawings, embodiments of the present invention will be described.

    [Fig. 1] is a schematic diagram showing a communication system according to an embodiment of the present invention.

    [Fig. 2] is a schematic diagram showing an example of the internal structure of an information processing device shown in Fig. 1.

    [Fig. 3] is a schematic diagram showing an example of information stored in a storage section shown in Fig. 2.

    [Fig. 4] is a schematic diagram showing an example of the internal structure of a mobile terminal shown in Fig. 1.

    [Fig. 5] is a sequence chart describing a communication method according to the embodiment shown in Fig. 1.



    [0008] Fig. 1 is a schematic diagram showing a communication system according to an embodiment of the present invention.

    [0009] The communication system according to this embodiment has information processing device 100, mobile terminals 200-1 to 200-2, and base station 300. Fig. 1 shows that there are two mobile terminals. It should be noted, however, that the number of mobile terminals may be three or more.

    [0010] Information processing device 100 can communicate with mobile terminals 200-1 to 200-2 through base station 300 and notifies mobile terminals 200-1 to 200-2 of the presence of other mobile terminals with which the former can perform the near field communication. The near field communication is a kind of radio communication that can transmit and receive signals in a range from several meters to several ten meters.

    [0011] Fig. 2 is a schematic diagram showing an example of the internal structure of information processing device 100 shown in Fig. 1.

    [0012] As shown in Fig. 2, information processing device 100 shown in Fig 1 has communication section 110, condition decision section 120, storage section 130, and control section 140. Fig. 2 shows only components relating to the present invention of those of information processing device 100 shown in Fig. 1.

    [0013] Communication section 110 acquires current location information that represents the current locations of mobile terminals 200-1 to 200-2 and user identification information that can identify the users who use mobile terminals 200-1 to 200-2. In addition to the user identification information, communication section 110 acquires supplementary user identification information. The supplementary user identification information is acquired using the near field communication function with which mobile terminals 200-1 to 200-2 are provided and which is user identification information that can identify users of other mobile terminals.

    [0014] Condition decision section 120 calculates the distance from a first location associated with the user information of each of the users who use mobile terminals 200-1 to 200-2 to the current location of each of mobile terminals 200-1 to 200-2. The user information and the first location associated therewith are pre-stored in storage section 130. The user information and the first location will be described later in detail. Communication section 110 acquires the current location from each of mobile terminals 200-1 to 200-2.

    [0015] Condition decision section 120 decides a condition based on the calculated distance. Under the condition, information processing device 100 notifies mobile terminals 200-1 to 200-2 of the presence of another mobile terminal with which the former performs the near field communication. At this point, condition decision section 120 decides a condition based on information stored in storage section 130.

    [0016] Storage section 130 individually pre-stores user information of users who use mobile terminals 200-1 to 200-2.

    [0017] Fig. 3 is a schematic diagram showing an example of information stored in storage section 130 shown in Fig. 2.

    [0018] As shown in Fig. 3, storage section 130 shown in Fig 2 correlatively pre-stores user identification information, user information, a first location, a distance range from the first location to the current location, and a condition.

    [0019] The user identification information is information that can identify a mobile terminal that belong to a user and is uniquely assigned to the mobile terminal. The user identification information may be, for example, an electronic mail address or a telephone number as long as information processing device 100 can designate a mobile terminal and set up a decided condition.

    [0020] The user information is information about the users who use mobile terminals 200-1 to 200-2. The user information may be, for example, the birth place of the user, the high school or university from which he or she graduated, the company to which he or she belongs, his or her address as long as any location can be identified.

    [0021] The first location represents a location associated with the user information. The first location may be, for example, an address, a city, or a prefecture and is information that represents a place (location) containing the user information. For example, as shown in Fig. 3, if the user information is "graduated from Metropolitan A High School," "Tokyo Metropolis" in which Metropolitan A High School is located may be first location information. If the user information is "graduated from Saitama Prefectural B High School," "Saitama Prefecture" in which Saitama Prefectural B High School is located may be first location information. It is preferable that the first location information be an area that is as narrow as possible as possible so that the distance to the current location (that will be described later) can be calculated.

    [0022] The distance ranges from the first location to the current location are the ranges that the distance from the pre-stored first location to the current location of each of mobile terminals 200-1 to 200-2 is divided into a plurality of ranges.

    [0023] The condition is the condition so that information processing device 100 notifies mobile terminals 200-1 to 200-2 of the presence of another mobile terminals.

    [0024] For example, user identification information "00000001," user information "graduated from Metropolitan A High School," first location "Tokyo Metropolis," distance range from the first location to the current location "50 km or less," and condition "graduated from Metropolitan A High School" are correlatively pre-stored. Thus, if the user information of the user whose user identification information is "00000001" is "graduated from Metropolitan A High School" and if the current location represented by the current location information acquired from the mobile terminal that belongs to the user is 50 km or less away from first location "Tokyo Metropolis," control section 140 notifies the mobile terminal whether or not there is another mobile terminal that has user information "graduated from Metropolitan A High School."

    [0025] In addition, user identification information "00000001," user information "graduated from Metropolitan A High School," first location "Tokyo Metropolis," distance range from the first location to the current location "51 km to 200 km," and condition "graduated from a high school in Tokyo Metropolis" are correlatively pre-stored. Thus, if the user information of the user whose user identification information is "00000001" is "graduated from Metropolitan A High School" and if the current location represented by the current location information acquired from the mobile terminal that belongs to the user is 51 km to 200 km away from first location "Tokyo Metropolis," control section 140 notifies the mobile terminal whether or not there is another mobile terminal that has user information "graduated from a high school in Tokyo Metropolis."

    [0026] In addition, user identification information "00000001," user information "graduated from Metropolitan A High School," first location "Tokyo Metropolis," distance range from the first location to the current location "201 km to 3000 km," and condition "graduated from a high school in the Metropolitan Area" are correlatively pre-stored. Thus, if the user information of the user whose user identification information is "00000001" is "graduated from Metropolitan A High School" and if the current location represented by the current location information acquired from the mobile terminal that belongs to the user is 201 km to 3000 km away from first location "Tokyo Metropolis," control section 140 notifies the mobile terminal whether or not there is another mobile terminal that has user information "graduated from a high school in the Metropolitan Area."

    [0027] In addition, user identification information "00000001," user information "graduated from Metropolitan A High School," first location "Tokyo Metropolis," distance range from the first location to the current location "3001 km or more," and condition "graduated from a high school in Japan" are correlatively pre-stored. Thus, if the user information of the user whose user identification information is "00000001" is "graduated from Metropolitan A High School" and if the current location represented by the current location information acquired from the mobile terminal that belongs to the user is 3001 km or more away from first location "Tokyo Metropolis," control section 140 notifies the mobile terminal whether or not there is another mobile terminal that has user information "graduated from a high school in Japan."

    [0028] In addition, user identification information "12345678," user information "graduated from Saitama Prefectural B High School," first location "Saitama Prefecture," distance range from the first location to the current location "50 km or less," and condition "graduated from Saitama Prefectural B High School" are correlatively pre-stored. Thus, if the user information of the user whose user identification information is "12345678" is "graduated from Saitama Prefectural B High School" and if the current location represented by the current location information acquired from the mobile terminal that belongs to the user is 50 km or less away from first location "Saitama Prefecture," control section 140 notifies the mobile terminal whether or not there is another mobile terminal that has user information "graduated from Saitama Prefectural B High School."

    [0029] In addition, user identification information "12345678," user information "graduated from Saitama Prefectural B High School," first location "Saitama Prefecture," distance range from the first location to the current location "51 km to 200 km," and condition "graduated from a high school in Saitama Prefecture" are correlatively pre-stored. Thus, if the user information of the user whose user identification information is "12345678" is "graduated from Saitama Prefectural B High School" and if the current location represented by the current location information acquired from the mobile terminal that belongs to the user is 51 km to 200 km away from first location "Saitama Prefecture," control section 140 notifies the mobile terminal whether or not there is another mobile terminal that has user information "graduated from a high school in Saitama Prefecture."

    [0030] In addition, user identification information "12345678," user information "graduated from Saitama Prefectural B High School," first location "Saitama Prefecture," distance range from the first location to the current location "201 km to 3000 km," and condition "graduated from a high school in the Metropolitan Area" are correlatively pre-stored. Thus, if the user information of the user whose user identification information is "12345678" is "graduated from Saitama Prefectural B High School" and if the current location represented by the current location information acquired from the mobile terminal that belongs to the user is 201 km to 3000 km away from first location "Saitama Prefecture," control section 140 notifies the mobile terminal whether or not there is another mobile terminal that has user information "graduated from a high school in the Metropolitan Area."

    [0031] In addition, user identification information "12345678," user information "graduated from Saitama Prefectural B High School," first location "Saitama Prefecture," distance range from the first location to the current location "3001 km or more," and condition "graduated from a high school in Japan" are correlatively pre-stored. Thus, if the user information of the user whose user identification information is "12345678" is "graduated from "Saitama Prefectural B High School" and if the current location represented by the current location information acquired from the mobile terminal that belongs to the user is 3001 km or more away from first location "Saitama Prefecture," control section 140 notifies the mobile terminal whether or not there is another mobile terminal that has user information "graduated from a high school in Japan."

    [0032] Control section 140 searches storage section 130 for user identification information that satisfies the condition decided by condition decision section 120. Thereafter, control section 140 transmits condition information that represents the condition and presence information that denotes whether or not other user identification information that satisfies the condition has been stored in storage section 130 as the result searched therefrom to mobile terminals 200-1 to 200-2 through communication section 110. At this point, control section 140 transmits the condition information and the presence information to a mobile terminal from which the former has acquired the user identification information and the current location information.

    [0033] If control section 140 has retrieved another user identification information that satisfies the condition from storage section 130, control section 140 transmits user information associated with the retrieved other user identification information to mobile terminals 200-1 to 200-2 through the communication section.

    [0034] In addition, control section 140 determines whether or not the supplementary user identification information acquired by communication section 110 satisfies the condition decided by condition decision section 120.

    [0035] Mobile terminals 200-1 to 200-2 are mobile radio communication devices that communicate with information processing device 100 through base station 300.

    [0036] Fig. 4 is a schematic diagram showing an example of the internal structure of mobile terminal 200-1 shown in Fig. 1. The internal structure of mobile terminal 200-2 shown in Fig. 1 is the same as that of mobile terminal 200-1.

    [0037] As shown in Fig. 4, mobile terminal 200-1 shown in Fig. 1 has communication section 210, near field communication section 220, and location information acquisition section 230. Fig. 4 shows only components that relate to the present invention of those of mobile terminal 200-1 shown in Fig. 1.

    [0038] Communication section 210 communicates with information processing device 100 through base station 300. In addition, communication section 210 transmits the current location information that is output from location information acquisition section 230 and the user identification information of the user that uses mobile terminal 200-1 to information processing device 100 through base station 300.

    [0039] Near field communication section 220 performs the near field communication with other mobile terminals based on information transmitted from information processing device 100. The near field communication is a kind of radio communication that is performed in a near distance and that uses Bluetooth or the like.

    [0040] Location information acquisition section 230 acquires location information that represents the current location of mobile terminal 200-1. For example, Location information acquisition section 230 may acquire location information from GPS (Global Positioning System) satellites using the GPS function. Location information acquisition section 230 outputs the acquired location information as current location information to communication section 210.

    [0041] Base station 300 is an ordinary radio base station that is connected to information processing device 100 and performs radio communication with mobile terminals 200-1 to 200-2.

    [0042] Next, a communication method according to this embodiment will be described. In this communication method, processes performed in information processing device 100 and mobile terminal 200-1 shown in Fig. 1 will be exemplified. The processes performed in mobile terminal 200-2 are the same as those performed in mobile terminal 200-1.

    [0043] Fig. 5 is a sequence chart describing the communication method according to the embodiment shown in Fig. 1.

    [0044] At step 1, location information acquisition section 230 of mobile terminal 200-1 acquires location information that represents the current location of mobile terminal 200-1.

    [0045] Thereafter, at step 2, communication section 210 of mobile terminal 200-1 transmits the location information acquired by location information acquisition section 230 as current location information to information processing device 100 through base station 300. At this point, communication section 210 transmits user identification information along with the location information. Thus, communication section 110 can acquire the current location information from mobile terminal 200-1.

    [0046] Communication section 110 of information processing device 100 receives the location information and user identification information from mobile terminal 200-1. Thereafter, at step 3, condition decision section 120 searches storage section 130 for first location associated with the user identification information as a search key.

    [0047] Thereafter, at step 4, condition decision section 120 calculates the distance from the location represented by the retrieved first location to the current location represented by the received current location information.

    [0048] Thereafter, at step 5, condition decision section 120 searches storage section 130 for a condition associated with the user identification information transmitted from mobile terminal 200-1 and the calculated distance and decides the condition as described with reference to Fig. 3.

    [0049] Thereafter, at step 6, control section 140 notifies mobile terminal 200-1 of the decided condition.

    [0050] Thereafter, communication section 210 of mobile terminal 200-1 receives the condition. Thereafter, at step 7, near field communication section 220 performs the near field communication with another mobile terminal based on the condition.

    [0051] After communication section 210 has received the condition, near field communication section 220 performs the near field communication in an ordinary manner.

    [0052] For example, if information processing device 100 has pre-stored the same information about mobile terminals 200-1 to 200-2 and has acquired their current locations, information processing device 100 determines whether or not there is another mobile terminal that satisfies the condition based on the current locations of mobile terminals 200-1 to 200-2. If there is such a mobile terminal, information processing device 100 transmits an ID as identification information of another mobile terminal to mobile terminals 200-1 to 200-2 along with the condition. When mobile terminals 200-1 to 200-2 receive the ID and condition, they start performing the near field communication based on the ID of another mobile terminal.

    [0053] In this example, a mobile terminal or the information processing device may determine whether or not there is another mobile terminal in the range of the near field communication of the former mobile terminal.

    [0054] If a mobile terminal determines whether or not there is another mobile terminal in the range of the near field communication, the former mobile terminal starts performing the near field communication at a predetermined timing and determines whether or not there is another mobile terminal in the area. If the former mobile terminal has determined that there is another mobile terminal, the former mobile terminal generates a sound or displays predetermined information so as to notify the user of the former mobile terminal that there is another mobile terminal in the area.

    [0055] If the information processing device determines whether there are mobile terminals in the range of the near field communication, the information processing device periodically acquires the current location information of the mobile terminals and determines whether or not there are mobile terminals that are close to each other based on the acquired current location information. If the information processing device has determined that there are mobile terminals that are close to each other, the information processing device notifies the mobile terminals that there are mobile terminals that are close to each other. The mobile terminals notify their users that there is another mobile terminal in the foregoing manner.

    [0056] Alternatively, mobile terminals 200-1 to 200-2 may have another function that determines whether or not there is another mobile terminal that is close to the former mobile terminal.

    [0057] For example, mobile terminal 200-1 pre-calculates the distance from its current location to the first location associated with the user information of mobile terminal 200-1 (this distance is denoted by distance a). Likewise, mobile terminal 200-2 pre-calculates the distance from its current location to the first location associated with the user information of mobile terminal 200-2 (this distance is denoted by distance b). Mobile terminal 200-1 determines that there is mobile terminal 200-2 that is close to mobile terminal 200-1 using a communication means (ordinary radio communication or near field communication).

    [0058] Information processing device 100 calculates the distance from the first location of mobile terminal 200-1 to the first location of mobile terminal 200-2 (this distance is denoted by distance L).

    [0059] Whether or not there are mobile terminals that are close to each other may be determined based on distances a, b, and L.

    [0060]  For example, if the relationship of L < a / 5 and (or) L < b / 5 is satisfied, mobile terminal 200-1 notifies its user that there is mobile terminal 200-2 close to mobile terminal 200-1.

    [0061] In other words, assuming that the greater are a and b than L, the higher is the value that the user has, mobile terminal 200-1 notifies him or her that there is another mobile terminal.

    [0062] The determination process may be performed by information processing device 100 or mobile terminals 200-1 to 200-2.

    [0063] Thus, a condition under which the user of a mobile terminal is notified of another mobile terminal with which the former mobile terminal performs the near field communication can be flexibly set up corresponding to the location of the former mobile terminal.

    [0064] The processes performed by the individual components of information processing device 100 may be accomplished by logic circuits that are manufactured to meet specific purposes. Alternatively, a computer program that describes contents of processes (hereinafter referred to as "program") may be recorded on a record medium from which information processing device 100 can read the program. The program recorded on the record medium may be read and executed by information processing device 100. The record medium from which the program can be read by information processing device 100 includes a movable record medium such as a floppy disk (registered trademark), a magneto optical disc, a DVD, or a CD, a memory such as a ROM or a RA M built in information processing device 100, or a HDD. The program recorded on the record medium is read by a CPU (not shown) of information processing device 100. The foregoing processes are performed under the control of the CPU. The CPU operates as a computer that executes the program that is read from the record medium.

    [0065] The present invention has been described with reference to the embodiments. However, it should be understood by those skilled in the art that the structure and details of the present invention may be changed in various manners without departing from the scope of the present invention as defined by the appended independent claim 1.
