The main storage unit 22 includes a RAM, for example. The auxiliary storage unit 23 includes, for example, a hard disk device (information storage medium). The optical disk drive unit 24 reads programs and data stored on an optical disk (information storage medium). The communication interface 25 is an interface for connecting the game server 20 to the communication network 12.

  Note that the game server 20 may include components for reading a program and data stored in an information storage medium (for example, a memory card) other than the optical disk. Then, the program and data may be supplied to the game server 20 via an information storage medium other than the optical disk. Or you may make it transmit a program and data to the game server 20 via the communication network 12 from the transmission apparatus provided with the information storage medium which memorize | stored the program and data.

  The game server 20 can access the database 14. The database 14 may be constructed in the game server 20 or may be constructed in a server computer different from the game server 20.

  The portable game machine 30 is a portable information processing terminal used by a user to play a game. The portable game machine 30 may be realized by a mobile phone, a portable information terminal, a smartphone, or the like. FIG. 3 shows a hardware configuration of the portable game machine 30. As shown in FIG. 3, the portable game machine 30 includes a control unit 31, a main storage unit 32, an auxiliary storage unit 33, a memory card slot unit 34, a communication interface 35, an operation unit 36, and a GPS (Global Positioning System) reception unit 37. , A display unit 38, and an audio output unit 39. The control unit 31, the main storage unit 32, and the auxiliary storage unit 33 are the same as the control unit 21, the main storage unit 22, and the auxiliary storage unit 23 of the game server 20.

  The memory card slot unit 34 reads programs and data stored in a memory card (information storage medium). The communication interface 35 is an interface for wirelessly connecting the portable game machine 30 to the communication network 12.

For example, the operation unit 36 includes a key, a button, a lever (stick), or a touch panel.

  The GPS receiver 37 receives a signal transmitted from a GPS satellite, and acquires the position (latitude and longitude) of the portable game machine 30 on the earth based on the signal. The display unit 38 is a liquid crystal display panel, for example, and displays a screen according to an instruction from the control unit 31. The audio output unit 39 is a speaker or a headphone terminal, for example, and outputs audio data according to an instruction from the control unit 31.

  The portable game machine 30 may include components for reading a program and data stored in an information storage medium (for example, an optical disc) other than the memory card. And you may make it a program and data supply to the portable game machine 30 via information storage media other than a memory card. Or you may make it transmit a program and data to the portable game machine 30 via the communication network 12 from the transmission apparatus provided with the information storage medium which memorize | stored the program and data.

  The portable game machine 30 can execute various games. In addition, the portable game machine 30 has a data transfer function. This data exchange function is a function in which game data is automatically exchanged between two portable game machines 30 when the two portable game machines 30 approach each other so that they can communicate wirelessly with each other. According to this data transmission / reception function, the user carries the portable game machine 30 with the power turned on, and by passing the portable game machine 30 with another user who also carries the portable game machine 30, his / her game data can be given to other users, The game data of other users can be obtained. That is, the user can easily enjoy the exchange of game data with other users.

  In the following description, it is assumed that game data including game item data acquired by the user in the game is exchanged between the portable game machines 30. Note that user data regarding the user may be included in the game data. For example, the user data is data including at least one of the user's self-introduction data, the user's voice comment data, the user's alternate avatar data, and the user's game play performance data.

  FIG. 4 shows an example of a notification screen for notifying the user that another user's game data has been obtained. By displaying this notification screen on the display unit 38, the user can know that the game data of another user has been obtained. In addition, the user can know information about other users and information about game items obtained from other users. According to such a data exchange function, the user can easily enjoy the exchange of game items with other users.

  Note that the game data to be subjected to the data transfer function may include other data instead of the game item data. For example, the game data may include game character data that the user has trained in the game. Further, for example, still image data, moving image data, or audio data may be included in the game data.

  By the way, in the data transfer function as described above, in areas where the number of users carrying the portable game machine 30 is small, there is less chance of passing with other users. It becomes difficult to be done. As a result, user satisfaction is reduced. In this regard, the game system 10 has a function for supporting a user who is in an area where the number of users carrying the portable game machine 30 is small so that data can be exchanged with other users. It has been. Hereinafter, this support function will be described.

  FIG. 5 is a functional block diagram illustrating an example of functional blocks realized by the game system 10. As shown in FIG. 5, the game system 10 includes a position data acquisition unit 40, a storage unit 41, an acquisition target region determination unit 42, an acquisition unit 43, a provision target region determination unit 44, and a provision unit 45.

  For example, the storage unit 41 is realized by the database 14 or the auxiliary storage unit 23. Note that the storage unit 41 may be realized by the auxiliary storage unit 33 of the portable game machine 30, for example. Alternatively, a part of the data described as being stored in the storage unit 41 may be stored in the database 14 or the auxiliary storage unit 23, and the remaining data may be stored in the auxiliary storage unit 33.

  On the other hand, functional blocks other than the storage unit 41 are realized by the game server 20 or the portable game machine 30. For example, all the functional blocks may be realized by the game server 20. Alternatively, all the functional blocks may be realized by the portable game machine 30. Alternatively, some functional blocks may be realized by the game server 20 and the rest may be realized by the portable game machine 30.

  Below, the case where the memory | storage part 41 is implement | achieved by the database 14 and the auxiliary storage part 23, and function blocks other than the memory | storage part 41 are implement | achieved by the game server 20 is demonstrated.

  First, the storage unit 41 will be described. The storage unit 41 stores various data. Specific examples of data stored in the storage unit 41 will be described later (see FIGS. 6, 8 to 12, 14 to 17, and FIG. 21).

  The position data acquisition unit 40 will be described. The position data acquisition unit 40 acquires position data regarding the position of each of the plurality of portable game machines 30. In the case of this embodiment, the portable game machine 30 transmits the position data (latitude and longitude data) acquired by the GPS receiving unit 37 to the game server 20 every predetermined time. The position data acquisition unit 40 acquires position data transmitted from the portable game machine 30.

  The position data transmitted from the portable game machine 30 to the game server 20 is not limited to the position data acquired by the GPS receiving unit 37. For example, a known technique for acquiring the position of a wireless LAN terminal based on radio waves transmitted from a wireless LAN access point device may be used. That is, based on the radio wave received from the access point device, the portable game machine 30 may acquire its own position data and transmit the acquired position data to the game server 20. Or, for example, the portable game machine 30 determines in which of a plurality of preset areas (for example, a plurality of areas A to Y shown in FIG. 7 to be described later), and Data indicating the area where the is located may be transmitted to the game server 20 as position data.

  Each position data of the plurality of portable game machines 30 is stored in the storage unit 41. FIG. 6 shows an example of a position table stored in the storage unit 41. The location table shown in FIG. 6 includes “terminal ID” and “location data” fields. Identification information (terminal ID) for uniquely identifying the portable game machine 30 is stored in the “terminal ID” field. In addition, the position data acquired by the position data acquisition unit 40 is stored in the “position data” field.

  In the case of this embodiment, the position data acquisition unit 40 acquires position data (latitude and longitude data) transmitted from the portable game machine 30, and stores the position data (latitude and longitude data) in the “position data” field. . The position data acquisition unit 40 determines whether the portable game machine 30 is located in a plurality of preset areas (for example, a plurality of areas A to Y shown in FIG. 7 described later). It may be determined based on the position data (latitude and longitude data) transmitted from the game machine 30 and data indicating the area where the portable game machine 30 is located may be stored in the “position data” field.

  The acquisition target area determination unit 42 and the acquisition unit 43 will be described. The acquisition target area determination unit 42 determines the acquisition target area. The acquisition unit 43 acquires game data from the portable game machine 30 located in the acquisition target area.

  The acquisition target area determination unit 42 determines the area as the acquisition target area based on the number of portable game machines 30 located in the area. For example, the acquisition target area determination unit 42 determines an area where a relatively large number of portable game machines 30 are located as the acquisition target area.

  In the case of this embodiment, a plurality of areas are set in advance in the real space. For example, when game data is exchanged between the portable game machines 30 in a specific area (for example, Japan), the specific area is divided into a plurality of areas. For example, when dividing Japan into a plurality of regions, it may be divided mechanically based on latitude and longitude, or may be divided based on administrative divisions (for example, municipalities).

  In the following, for simplification of explanation, it is assumed that 25 areas A to Y as shown in FIG. 7 are set in the real space. In this case, data indicating the areas A to Y is stored in the storage unit 41. FIG. 8 shows an example of an area table stored in the storage unit 41. The area table shown in FIG. 8 includes “area ID” and “area data” fields. The “area ID” field indicates identification information (area ID) for uniquely identifying each of the areas A to Y. The “region data” field indicates data for specifying a region. For example, data indicating conditions regarding the latitude and longitude of positions included in the region and data regarding the area of the region are stored in the “region data” field.

  Further, in this case, based on the position data (latitude and longitude data) of each portable game machine 30, it is determined which of the 25 areas A to Y each portable game machine 30 is located. For each area A to Y, the number of portable game machines 30 located in the area is counted, and the result is stored in the storage unit 41. FIG. 9 shows an example of the terminal number table. The terminal number table shown in FIG. 9 includes “area ID” and “terminal number” fields. The “area ID” field is the same as the “area ID” field of the area table. The “number of terminals” field indicates the number of portable game machines 30 located in the area.

  The acquisition target area determination unit 42 determines at least one of the plurality of areas A to Y as an acquisition target area. The acquisition target area determination unit 42 determines at least one of the plurality of areas A to Y as an acquisition target area based on the number of portable game machines 30 located in each of the plurality of areas A to Y.

  For example, the acquisition target area determination unit 42 determines the area having the largest number of portable game machines 30 as the acquisition target area. Alternatively, the acquisition target area determination unit 42 may determine an area where the number of the portable game machines 30 is the first to nth (n: integer greater than or equal to 2) as the acquisition target area. Alternatively, the acquisition target area determination unit 42 may determine an area where the number of portable game machines 30 is equal to or greater than the reference number as the acquisition target area.

  Further, for example, the acquisition target area determination unit 42 determines at least one of the plurality of areas A to Y as the acquisition target area based on the density of the portable game machine 30 in each of the plurality of areas A to Y. It may be. The “density of the portable game machine 30 in the area” is a numerical value obtained by dividing the number of portable game machines 30 located in the area by the area of the area.

  For example, the acquisition target area determination unit 42 may determine an area where the density of the portable game machine 30 is the highest as the acquisition target area. Alternatively, the acquisition target area determination unit 42 may determine an area where the density of the portable game machine 30 is the first to nth (n: integer greater than or equal to 2) as the acquisition target area. Alternatively, the acquisition target region determination unit 42 may determine a region where the density of the portable game machine 30 is equal to or higher than a reference value as the acquisition target region.

  The determination result of the acquisition target area determination unit 42 is stored in the storage unit 41. FIG. 10 shows an example of acquisition target area data stored in the storage unit 41. The acquisition target area data is data indicating the acquisition target area determined by the acquisition target area determination unit 42. The acquisition target area data illustrated in FIG. 10 indicates that the area A is determined as the acquisition target area.

  As described above, the acquisition unit 43 acquires game data from the portable game machine 30 located in the acquisition target area. In the case of this embodiment, the portable game machine 30 transmits game data including user's self-introduction data and game item data to the game server 20. And the acquisition part 43 receives the game data transmitted from the portable game machine 30. Note that even if game data (game item data) is transmitted from the portable game machine 30 to the game server 20, the game data does not disappear from the portable game machine 30. Even after the transmission is executed, the game data remains in the portable game machine 30.

  Data acquired by the acquisition unit 43 is stored in the storage unit 41. FIG. 11 shows an example of a game data table stored in the storage unit 41. The game data table shown in FIG. 11 includes “terminal ID”, “game data”, and “provable number of people” fields. The “terminal ID” field indicates from which portable game machine 30 the game data is acquired. In the “game data” field, game data acquired by the acquisition unit 43 is stored. The “providable number” field indicates the number of users who can provide game data. When the value of the “providable number of people” field is “10”, it indicates that the remaining number of users who can obtain game data is ten. The game data table may include a “terminal position” field that indicates the position (latitude and lightness) of the portable game machine 30 together with the “terminal ID” field.

  The provision target area determination unit 44 and the provision unit 45 will be described. The provision target area determination unit 44 determines a provision target area. The providing unit 45 controls the game data based on the game data acquired by the acquiring unit 43 to be provided to the user in the portable game machine 30 located in the providing target area.

  The provision target area determining unit 44 determines the area as the provision target area based on the number of the portable game machines 30 located in the area. For example, the provision target region determining unit 44 determines a region having a relatively small number of portable game machines 30 as the provision target region.

  When 25 areas A to Y as shown in FIG. 7 are set in the real space, the provision target area determination unit 44 is based on the number of portable game machines 30 located in each of the plurality of areas A to Y. Thus, at least one of the plurality of areas A to Y is determined as the provision target area.

  For example, the provision target area determining unit 44 determines the area having the smallest number of portable game machines 30 as the provision target area. Alternatively, the provision target area determining unit 44 may determine the first to nth (n: integer greater than or equal to 2) number of portable game machines 30 as the provision target area. Alternatively, the provision target area determination unit 44 may determine an area where the number of portable game machines 30 is less than the reference number as the provision target area.

  Further, for example, the provision target area determination unit 44 determines at least one of the plurality of areas A to Y as the provision target area based on the density of the portable game machine 30 in each of the plurality of areas A to Y. It may be. For example, the provision target area determination unit 44 may determine the area where the density of the portable game machine 30 is the lowest as the provision target area. Alternatively, the provision target area determination unit 44 may determine an area where the density of the portable game machine 30 is the first to nth (n: integer greater than or equal to 2) as the provision target area. Alternatively, the provision target region determination unit 44 may determine a region where the density of the portable game machine 30 is less than the reference value as the provision target region.

  The determination result of the provision target area determination unit 44 is stored in the storage unit 41. FIG. 12 shows an example of provision target area data stored in the storage unit 41. The provision target area data is data indicating the provision target area determined by the provision target area determination unit 44. The provision target area data illustrated in FIG. 12 indicates that the area Y is determined as the provision target area.

  As described above, the providing unit 45 performs control such that game data based on the game data acquired by the acquiring unit 43 is provided to the user in the portable game machine 30 located in the providing target area.

  The “game data based on the game data acquired by the acquisition unit 43” is, for example, the game data itself acquired by the acquisition unit 43. In the following description, it is assumed that “game data based on the game data acquired by the acquisition unit 43” is the game data itself acquired by the acquisition unit 43. The “game data based on the game data acquired by the acquisition unit 43” may be game data obtained based on the game data acquired by the acquisition unit 43. For example, game data obtained by changing at least a part of the game data acquired by the acquisition unit 43 may be used. Details of this case will be described later.

  In the case of the present embodiment, the providing unit 45 transmits the game data acquired by the acquiring unit 43 to the portable game machine 30 located in the provision target area, so that the game data is transmitted to the user in the portable game machine 30. Control as provided.

  “Providing game data to the user in the portable game machine 30” means, for example, presenting game data to the user by causing the display unit 38 or the audio output unit 39 to output the game data in the portable game machine 30. Including. For example, when game data includes other user's self-introduction data or other user's game item data, presenting the self-introduction data or game item data to the user may indicate that “the game data is stored in Is equivalent to

  Alternatively, “providing game data to the user at the portable game machine 30” includes, for example, allowing the game data to be used in a game played by the user on the portable game machine 30. For example, when game item data of another user is included in the game data, it may be possible for a user to use the game item in a game executed on the portable game machine 30. Corresponds to “providing to the user”.

  In the game system 10 described above, for example, an area where the density of the portable game machine 30 is high is determined as the acquisition target area, and an area where the density of the portable game machine 30 is low is determined as the provision target area. And it controls so that the game data based on the game data acquired from the portable game machine 30 located in an acquisition object area | region will be provided to a user in the portable game machine 30 located in a provision object area | region. As a result, even a user who is in an area where the number of users carrying the portable game machine 30 is small can enjoy exchange of game data with other users.

  By the way, the acquisition target area may be moved with time. Further, the acquisition target area determination unit 42 may determine the movement path of the acquisition target area based on the number of portable game machines 30 located in each of the plurality of areas A to Y. For example, the acquisition target area determination unit 42 may determine the movement path of the acquisition target area so that the acquisition target area moves toward the provision target area.

  FIG. 13 is a diagram for explaining an example of a method for determining a movement route of an acquisition target area. In the method shown in FIG. 13, first, based on the number of portable game machines 30 located in each of the plurality of areas A to Y, any one of the plurality of areas A to Y is the first acquisition target. Select as region. For example, the area with the highest density of the portable game machine 30 (or the area with the largest number of portable game machines 30) is selected as the first acquisition target area. The example illustrated in FIG. 13 illustrates a case where the area A is selected as the first acquisition target area.

  Moreover, based on the number of the portable game machines 30 located in each of the plurality of areas A to Y, any one of the plurality of areas A to Y is selected as the provision target area. For example, the area where the density of the portable game machine 30 is the lowest (or the area where the number of the portable game machines 30 is the smallest) is selected as the provision target area. The example illustrated in FIG. 13 illustrates a case where the area O is selected as the provision target area.

  Furthermore, from a reference position 50 (for example, center position) set in the first acquisition target area (area A), a reference position 51 (for example, center position of area O) set in the provision target area (area O) ) To the line 52). Then, the region through which the line 52 passes is determined as the acquisition target region in the order in which the line 52 passes through. In the example illustrated in FIG. 13, the region B is determined as the second acquisition target region. Similarly, the regions G, H, I, and N are determined as the third to sixth acquisition target regions, respectively. The line 52 connecting the reference position 50 of the first acquisition target region (region A) and the reference position 51 of the provision target region (region O) is not limited to a straight line, and may be a curve, for example.

  When the acquisition target area changes with time, for example, acquisition target area data as shown in FIG. 14 is stored in the storage unit 41. Note that the acquisition target area data illustrated in FIG. 14 indicates the result determined in the example illustrated in FIG. That is, the acquisition target area data illustrated in FIG. 14 indicates that the area A is an acquisition target area in the first period, and the areas B, G, and H are respectively acquired in the second to sixth periods. , I, and N indicate acquisition target areas. In this case, each of the first to sixth periods may be a predetermined time period (for example, 10 minutes). That is, if the area A is set as the acquisition target area in the first period (first 10 minutes), and the area B is set as the acquisition target area in the second period (next 10 minutes). Good.

  In the acquisition target area data, each period may be expressed by date and time. FIG. 15 shows an example of the acquisition target area data in this case.

  If the acquisition target area is moved as described above, game data can be obtained from more portable game machines 30, and as a result, various game data can be obtained. The various game data can be provided to a user in an area where the number of users carrying the portable game machine 30 is small. Further, by moving the acquisition target area toward the provision target area, it is as if the tornado moves to the provision target area while winding up the game data from the portable game machine 30, and the tornado disappears in the provision target area. It is possible to perform such an effect that the game data rolled up so far is scattered. As a result, it is possible to improve the interest related to the exchange of game data.

  Note that the lengths of the periods in the acquisition target region data illustrated in FIGS. 14 and 15 may not be the same. That is, you may make it set the length of a period for every period. FIG. 16 shows an example of the acquisition target area data when the length of the period is set for each period. In the example shown in FIG. 16, the length of the first period is 15 minutes, and the length of the second period is 5 minutes. In this case, the area A is set as the acquisition target area in the first 15 minutes (first period), and the area B is set as the acquisition target area in the next five minutes (second period).

  When the length of each period is set for each period, the length of each period may be determined based on the number of portable game machines 30 in the area set as the acquisition target area in that period. . In this case, the storage unit 41 may store information that associates information about the number of portable game machines 30 with information about the length of the period. FIG. 17 shows an example of the information. In the information shown in FIG. 17, the density of the portable game machine 30 is associated with the length of the period. In the information shown in FIG. 17, “D1” and “D2” indicate predetermined densities. In the information shown in FIG. 17, the length of the period becomes longer as the density of the portable game machine 30 is higher.

  In this way, the length of the period for acquiring the game data can be changed based on the number of portable game machines 30 located in the area, and as a result, the acquisition of the game data is efficiently performed. Can be done automatically. For example, in a region where the density of the portable game machine 30 is high, a period for obtaining game data can be set relatively long, and as a result, game data can be obtained from more portable game machines 30. Become. On the other hand, in the area where the density of the portable game machine 30 is low, it is not expected to obtain game data from many portable game machines 30 even if the period for obtaining the game data is set to be relatively long. In this regard, as described above, in a region where the density of the portable game machine 30 is low, it is possible to set a relatively short period for acquiring game data.

  Next, processing executed in the game system 10 will be described. Here, in particular, for a user in an area where the number of users carrying the portable game machine 30 is small, a function for supporting the exchange of game data with other users is realized. The process will be described.

  In the game system 10, each of the plurality of portable game machines 30 transmits position data indicating its own position together with its own terminal ID to the game server 20 every predetermined time. When the terminal ID and the position data are received by the game server 20, the control unit 21 (position data acquisition unit 40) registers the combination of the terminal ID and the position data in the position table (FIG. 6). When the terminal ID is already registered in the position table, the control unit 21 updates the position data associated with the terminal ID to the newly received position data.

  In the game system 10, for example, a process as shown in FIG. 18 is executed as a process for realizing the support function. The process shown in FIG. 18 is executed by the control unit 21 of the game server 20. The control unit 21 executes the processing shown in FIG. 18 according to the program stored in the auxiliary storage unit 23, so that the control unit 21 acquires the acquisition target region determination unit 42, the acquisition unit 43, the provision target region determination unit 44, and the provision Functions as the unit 45.

  As shown in FIG. 18, first, the control unit 21 determines the number of portable game machines 30 located in each of the plurality of areas A to Y based on the position table (FIG. 6) and the area table (FIG. 8). Calculate (S101). The control unit 21 stores the calculation result in the storage unit 41 as a terminal number table (FIG. 9).

  After the process of step S101 is executed, the control unit 21 (the acquisition target region determination unit 42 and the provision target region determination unit 44) determines the acquisition target region and the provision target region (S102). For example, the control unit 21 determines an area where the density of the portable game machine 30 is the highest among the plurality of areas A to Y as an acquisition target area, and the density of the portable game machine 30 is the density among the plurality of areas A to Y. The lowest area is determined as the provision target area. Alternatively, by the method described with reference to FIG. 13, the control unit 21 determines a plurality of the plurality of regions A to Y as acquisition target regions, and provides one of the plurality of regions A to Y to be provided. You may make it determine as. Note that the density of the portable game machine 30 in each of the plurality of areas A to Y is calculated based on the terminal number table (FIG. 9) and the area table (FIG. 8). The control unit 21 stores the determination result in the storage unit 41 as acquisition target region data (FIGS. 10, 14 to 16) and provision target region data (FIG. 12).

  After the process of step S102 is performed, the control part 21 starts acquisition of game data (S103). FIG. 19 is a diagram for explaining an example of processing executed when acquisition of game data is started.

  As described above, each of the plurality of portable game machines 30 transmits the terminal ID and the position data to the game server 20 every predetermined time (S201). When the terminal ID and the position data are received by the game server 20 after starting the acquisition of the game data, the control unit 21 updates the position table (S202), and the portable game machine 30 is within the acquisition target area. It is determined whether it is located in (S203).

  For example, as shown in FIG. 10, when one area (for example, area A) is determined as the acquisition target area, the control unit 21 determines whether or not the portable game machine 30 is located in the area (area A). Determine whether. Further, for example, as illustrated in FIGS. 14 to 16, when the acquisition target area is determined to change over time, the control unit 21 determines whether or not the portable game machine 30 is located in the acquisition target area at the current time. Determine whether.

  When it is determined that the portable game machine 30 is located within the acquisition target area, the control unit 21 (acquisition unit 43) sends data for requesting the portable game machine 30 to transmit the game data. It transmits to the machine 30 (S204). And when this data is received with the portable game machine 30, the control part 31 transmits game data to the game server 20 with own terminal ID (S205). For example, the control unit 31 acquires user data and game item data from the auxiliary storage unit 33 (or memory card), and transmits game data including these data to the game server 20.

  When game data is received by the game server 20, the control unit 21 (acquisition unit 43) registers the received terminal ID and game data in the game data table (S206). For example, when the received terminal ID is not registered in the game data table, the control unit 21 adds a new record to the game data table, and the “terminal ID” and “game data” fields of the record respectively. The received terminal ID and game data are registered. Further, the control unit 21 registers a predetermined initial value in the “number of people that can be provided” field. On the other hand, when the received terminal ID is already registered in the game data table, the control unit 21 updates the game data associated with the received terminal ID to the newly received game data.

  On the other hand, if it is determined in step S203 that the portable game machine 30 is not located within the acquisition target area, the processes in steps S204 to S206 are not executed. When it is determined in step S203 that the portable game machine 30 is located within the acquisition target area, the control unit 21 determines whether or not the terminal ID of the portable game machine 30 is already registered in the game data table. May be determined. If the terminal ID of the portable game machine 30 is already registered in the game data table, the processes in steps S204 to S206 may not be executed.

  As shown in FIG. 18, after starting acquisition of game data, the control unit 21 monitors whether or not the acquisition period of game data has ended (S104). For example, as shown in FIG. 10, when one area (for example, area A) is determined as the acquisition target area, the control unit 21 has passed a predetermined time (for example, 10 minutes) after starting to acquire game data. Monitor whether or not For example, as illustrated in FIGS. 14 to 16, when the acquisition target region is determined to change with time, the control unit 21 performs the last period (the sixth period in the case of FIGS. 14 to 16). ) Is monitored.

  When it is determined that the game data acquisition period has ended, the control unit 21 starts providing game data (S105). FIG. 20 is a diagram for describing an example of processing executed when provision of game data is started.

  As described above, each of the plurality of portable game machines 30 transmits the terminal ID and the position data to the game server 20 every predetermined time (S301). When the terminal ID and the position data are received by the game server 20 after the provision of the game data is started, the control unit 21 updates the position table (S302), and the portable game machine 30 is within the provision target area. It is determined whether it is located in (S303).

  When it is determined that the portable game machine 30 is located within the provision target area, the control unit 21 acquires probability information for determining whether or not to transmit game data to the portable game machine 30 (S304). ). For example, the control unit 21 acquires probability information based on the distance between the position of the portable game machine 30 and a reference position (for example, the center position) set in the provision target area. For example, the process of step S304 is executed based on the information shown in FIG. FIG. 21 shows information for acquiring probability information, specifically, information obtained by associating distance with probability information. In the information shown in FIG. 21, “L1”, “L2”, and “L3” indicate predetermined distances. In the information shown in FIG. 21, the probability that it is determined that game data is transmitted to the portable game machine 30 increases as the distance between the position of the portable game machine 30 and the reference position of the provision target area becomes shorter. ing. In step S304, the control unit 21 acquires probability information corresponding to the distance between the position of the portable game machine 30 and the reference position of the provision target area based on the information illustrated in FIG.

  After the process of step S304 is executed, the control unit 21 determines whether or not to transmit game data to the portable game machine 30 based on the probability information acquired in step S304 (S305). For example, in the information shown in FIG. 21, as the distance between the position of the portable game machine 30 and the reference position of the provision target area becomes shorter, the probability that the game data is determined to be transmitted to the portable game machine 30 increases. Is set. For this reason, the shorter the distance between the position of the portable game machine 30 and the reference position of the provision target area, the higher the probability that the game data is determined to be transmitted to the portable game machine 30 in step S305.

  When it is determined to transmit game data to the portable game machine 30, the control unit 21 selects at least one of the game data registered in the game data table (FIG. 11). For example, the control unit 21 selects at least one game data in which the number of people that can be provided is not zero. Then, the control unit 21 (providing unit 45) transmits the selected game data to the portable game machine 30 (S306). Further, the control unit 21 decreases the number of people who can provide the game data transmitted to the portable game machine 30 by 1 in the game data table (FIG. 11) (S307).

  On the other hand, the portable game machine 30 that has received the game data stores the game data in the auxiliary storage unit 23 (or memory card), and displays a notification screen (FIG. 4) on the display unit 38 (S308).

  If it is determined in step S303 that the portable game machine 30 is not located within the provision target area, the processes in steps S304 to S308 are not executed. If it is determined in step S305 that game data is not transmitted to the portable game machine 30, the processes in steps S306 to S308 are not executed. That is, in these cases, game data is not transmitted to the portable game machine 30, and as a result, other users' game data is not provided to the user of the portable game machine 30.

  As shown in FIG. 18, after providing the game data is started, the control unit 21 monitors whether or not the game data providing period has ended (S106). For example, the control unit 21 monitors whether or not a predetermined time (for example, 10 minutes) has elapsed since the start of the provision of game data.

  When it is determined that the game data provision period has ended, the control unit 21 ends this process. In this case, the control unit 21 re-executes the processes of steps S101 to S106. That is, new acquisition target areas and provision target areas are determined, and game data is exchanged between the portable game machines 30 located in these areas.

  In the game system 10 described above, the area is determined as the provision target area based on the number of the portable game machines 30 located in the area. For example, an area where the density of the portable game machine 30 is relatively low is determined as the provision target area. And it controls so that the game data acquired from the portable game machine 30 located in an acquisition object area | region may be provided to a user in the portable game machine 30 located in a provision object area | region. According to the game system 10, even in a region where the number of users carrying the portable game machine 30 is small, it is possible to enjoy the exchange of game data with other users. .

  In the game system 10, the area is determined as the acquisition target area based on the number of the portable game machines 30 located in the area. For example, an area where the density of the portable game machine 30 is relatively high is determined as the acquisition target area. According to the game system 10, it is possible to collect a large amount of game data to be provided to a user who is in a provision target area (an area where the number of users carrying the portable game machine 30 is small).

  Further, in the game system 10, the acquisition target area moves with time. In addition, the movement path of the acquisition target area is determined based on the number of portable game machines 30 in each area. Specifically, the movement path of the acquisition target area is determined such that the acquisition target area moves toward the provision target area. According to the game system 10, it is possible to improve the interest related to the game data exchange function.

  The control unit 21 of the game server 20 may transmit data for displaying a screen for guiding the moving route of the acquisition target area to the user to the portable game machine 30. The above screen may be displayed on the display unit 38 of the portable game machine 30. This makes it possible for the user to grasp how the acquisition target area moves, and as a result, it is possible to further improve the interest related to the game data exchange function.

  Further, in the game system 10, for example, the probability that game data is provided to the user of the portable game machine 30 located in the provision target area by executing the processing of steps S <b> 304 and S <b> 305 in FIG. It changes based on the distance between the position of and the reference position of the provision target area. Specifically, the shorter the distance, the higher the probability. According to the game system 10, the ease with which the game data is provided to the user varies depending on the distance between the position of the portable game machine 30 and the reference position of the provision target area. As a result, it is possible to further improve the interest related to the game data exchange function.

  Note that data for displaying a screen for guiding the reference position of the provision target area to the user may be transmitted to the portable game machine 30, and the screen may be displayed on the display unit 38 of the portable game machine 30. . In this way, the reference position of the provision target area may be guided to the user. In this way, it becomes possible for the user to know the reference position of the provision target area, so that the user knows which position in the provision target area is closer to obtaining game data of other users. It becomes possible to make it. As a result, it is possible to further improve the interest related to the game data exchange function.

  The present invention is not limited to the embodiment described above.

  (1) For example, instead of the processes of steps S203 to S205 in FIG. 19, the processes of steps S401 to S403 shown in FIG. 22 may be executed. The processes in steps S401 to S403 are different from the processes in steps S203 to S205 in FIG. 19 in that the portable game machine 30 determines whether or not the portable game machine 30 is located in the acquisition target area. Yes.

  In the process shown in FIG. 22, the control unit 21 of the game server 20 transmits the acquisition target area data (FIGS. 10, 14 to 16) and area data (FIG. 8) to the portable game machine 30 (S401). And when these data are received by the portable game machine 30, the control part 31 determines whether an own position is in an acquisition object area | region (S402). For example, as shown in FIG. 10, when one area (for example, area A) is determined as the acquisition target area, the control unit 31 determines whether or not its own position is included in the area (area A). Determine. Also, for example, as shown in FIGS. 14 to 16, when it is determined that the acquisition target area changes with the passage of time, the control unit 31 determines whether or not its own position is included in the acquisition target area at the present time. judge.

  When it is determined that the position of the portable game machine 30 is within the acquisition target area, the control unit 31 acquires game data from the auxiliary storage unit 33 (or memory card), and stores the game data together with the terminal ID to the game server 20. Transmit (S403). When the terminal ID and the game data are received by the game server 20, the control unit 21 (acquisition unit 43) registers the received terminal ID and game data in the game data table (S206). If it is determined that the position of the portable game machine 30 is not within the acquisition target area, the processes of steps S403 and S206 are not executed.

  (2) For example, instead of the processing of steps S303 to S308 in FIG. 20, the processing of steps S501 to S508 shown in FIG. 23 may be executed. The processes in steps S501 to S508 are different from the processes in steps S303 to S308 in FIG. 20 in that the portable game machine 30 determines whether or not the portable game machine 30 is located in the provision target area. Yes.

  In the process shown in FIG. 23, the control unit 21 of the game server 20 transmits the provision target area data (FIG. 12) and the area data (FIG. 8) to the portable game machine 30 (S501). When these data are received by the portable game machine 30, the control unit 31 determines whether or not its position is within the provision target area (S502). When it determines with the position of the portable game machine 30 being in a provision object area | region, the control part 31 acquires the probability information for determining whether to provide game data to a user (S503). Then, the control unit 31 determines whether or not to provide game data to the user based on the probability information (S504). The processes in steps S503 and S504 are the same as the processes in steps S304 and S305 in FIG. In this case, information similar to the information shown in FIG. 21 is stored in the auxiliary storage unit 33 (or memory card).

  When it is determined to provide the game data to the user, the control unit 31 transmits data for requesting to transmit the game data to the game server 20 (S505). When this data is received by the game server 20, the control unit 21 (providing unit 45) selects at least one of the game data registered in the game data table (FIG. 11) and selects the selected game. Data is transmitted to the portable game machine 30 (S506). Further, the control unit 21 decreases the number of people who can provide the game data transmitted to the portable game machine 30 by 1 in the game data table (FIG. 11) (S507). The processing in these steps 506 and 507 is the same as the processing in steps S306 and S307 in FIG.

  When the game data is received by the portable game machine 30, the control unit 31 stores the game data in the auxiliary storage unit 23 (or memory card) and displays a notification screen (FIG. 4) on the display unit 38 (S508). . The processing in step 508 is the same as the processing in step S308 in FIG.

  If it is determined in step S502 that the portable game machine 30 is not located within the provision target area, the processes in steps S503 to S508 are not executed. If it is determined in step S504 that the game data is not provided to the user, the processes in steps S505 to S508 are not executed. That is, in these cases, the game data of other users is not transmitted to the portable game machine 30, and as a result, the game data of other users is not provided to the user of the portable game machine 30.

  (3) For example, instead of the processes of steps S501 to S508 in FIG. 23, the processes of steps S601 to S609 shown in FIG. 24 may be executed. The processes in steps S601 to S609 are different from the processes in steps S501 to S508 in FIG. 23 in that game data is transmitted from the game server 20 to the portable game machine 30 together with the provision target area data.

  In the process shown in FIG. 24, the control unit 21 (providing unit 45) of the game server 20 transmits the provision target area data (FIG. 12), the area data (FIG. 8), and the game data to the portable game machine 30 (S601). . When these data are received by the portable game machine 30, the control unit 31 stores the received game data in the auxiliary storage unit 23 (or memory card) in a state where provision to the user is restricted (prohibited). (S602).

  After the process of step S602 is executed, the control unit 31 determines whether or not its position is within the provision target area (S603). And when it determines with the position of the portable game machine 30 being in a provision object area | region, the control part 31 acquires the probability information for determining whether to provide game data to a user (S604). Further, the control unit 31 determines whether or not to provide game data to the user based on the probability information (S605). The processes in steps S603 to S605 are the same as the processes in steps S502 to S504 in FIG.

  When it is determined that the game data is to be provided to the user, the control unit 31 releases the provision restriction imposed on the game data (S606), and changes the game data to a state in which provision to the user is not restricted (prohibited). To do. That is, the control part 31 permits provision of game data to the user. Further, the control unit 31 transmits data for notifying the user that the game data has been provided to the game server 20 (S607), and the game data is changed to a state in which the provision to the user is not restricted (prohibited). Based on this, a notification screen (FIG. 4) is displayed on the display unit 38 (S608).

  On the other hand, when the data transmitted in step S607 is received by the game server 20, the control unit 21 decreases the number of people that can transmit the game data provided to the user by 1 (S609). The processing in step S609 is the same as the processing in step 507 in FIG.

  (4) For example, similarly to the acquisition target area, the provision target area may be changed over time. For example, the provision target area may also move along the movement path as time passes. In this case, the provision target area determination unit 44 may determine the movement path of the provision target area based on the number of portable game machines 30 located in each of the plurality of areas A to Y. For example, in FIG. 13, the regions B, G, H, I, and N may be determined as the first to fifth provision target regions, and the region O may be the sixth provision target region. .

  Also, other methods may be adopted as a method for determining the movement route of the provision target area. FIG. 25 is a diagram for explaining another example of the method for determining the movement route of the provision target area. Here, it is assumed that the acquisition target area is the area A.

  In the determination method shown in FIG. 25, first, one of the areas in the vicinity of area A is determined as the first provision target area based on the number of portable game machines 30 located in each of these areas. To do. For example, among the regions B, F, and G adjacent to the region A, the region with the lowest density of the portable game machine 30 is determined as the first provision target region. In the example shown in FIG. 25, the area G is determined as the first provision target area.

  After that, any one of the areas in the vicinity of the i-th provision target area is determined as the i + 1-th provision target area based on the number of portable game machines 30 located in those areas. To do. That is, any one of the areas in the vicinity of the area G is determined as the second provision target area based on the number of portable game machines 30 located in each of the areas. For example, among the areas adjacent to the area G, the area with the lowest density of the portable game machine 30 is determined as the second provision target area. In this case, the area A that is the acquisition target area and the areas B and F that are the candidates for the first provision target area are excluded from the candidates for the second provision target area. That is, among the regions C, H, K, L, and M, the region with the lowest density of the portable game machine 30 is determined as the second provision target region. In the example shown in FIG. 25, the region L is determined as the second provision target region.

  Next, any one of the areas in the vicinity of the area L is determined as the third provision target area based on the number of the portable game machines 30 located in each of the areas. For example, among the areas adjacent to the area L, the area with the lowest density of the portable game machine 30 is determined as the third provision target area. In this case, the area A that is the acquisition target area, the G that is the first provision target area, and the areas B, C, F, H, and K that are candidates for the first and second provision target areas. , M are excluded from candidates for the third provision target area. That is, of the areas P, Q, and R, the area with the lowest density of the portable game machine 30 is determined as the third provision target area. In the example shown in FIG. 25, the region R is determined as the third provision target region.

  Similarly, the fourth and fifth provision target areas are determined. In the example shown in FIG. 25, the areas X and T are determined as the fourth and fifth provision target areas. In this case, the upper limit number (for example, 5) of the provision target area may be determined.

  (5) For example, the acquisition target region determination unit 42 may determine a region having a relatively small number of portable game machines 30 as the acquisition target region. In this way, between a user who is in an area where the number of users carrying the portable game machine 30 is relatively small and a user who is in another area where the number of users carrying the portable game machine 30 is relatively small. In this case, game data may be exchanged.

  (6) For example, game data may be provided to the user of the portable game machine 30 located in the provision target area. That is, steps S304 and S305 in FIG. 20 may be removed. Similarly, steps S503 and S504 in FIG. 23 and steps S604 and S605 in FIG. 24 may be removed.

  (7) For example, the “provable number of people” field of the game data table (FIG. 11) may be removed. In this way, an upper limit number of people who can provide game data may not be provided.

  (8) For example, when two portable game machines 30 approach each other so that they can communicate wirelessly with each other, the function of automatically transferring game data between the portable game machines 30 is not an essential function. Each portable game machine 30 may not have the function. The game data may be exchanged only by the function described as the support function in the embodiment described above.

  (9) For example, as described above, the providing unit 45 allows the user in the portable game machine 30 in which the game data obtained by changing at least a part of the game data acquired by the acquiring unit 43 is located in the provision target area. You may make it control so that it may be provided. For example, when the game item data is included in the game data, the game data including the game item data in which the effect of the game item is improved or reduced is “at least a part of the game data acquired by the acquisition unit 43 is included. This corresponds to “changed game data”.

  In this case, the game data may be changed when the game data is received from the portable game machine 30 located in the acquisition target area (step S205 in FIG. 19 or step S403 in FIG. 22). It may be performed when transmission to the portable game machine 30 located in the provision target area is executed (step S306 in FIG. 20, step S506 in FIG. 23, and step S601 in FIG. 24). Further, the game data may be changed when releasing the provision restriction imposed on the game data by the user (step S606 in FIG. 24).

  (10) For example, when game data (game item data) is transmitted from the portable game machine 30 located within the acquisition target area to the game server 20 (step S205 in FIG. 19 and step S403 in FIG. 22), the game item The data may be invalidated in the portable game machine 30, or the game item data may be deleted from the portable game machine 30. That is, you may make it take a game item from the user of the portable game machine 30.

  (11) For example, the present invention can be applied to a system other than a game system. For example, the present invention can be applied to a case where a data exchange system that exchanges data (for example, user self-introduction data) between smartphones is realized.
