  Embodiments according to the present invention will be described below in detail with reference to the drawings. In the first embodiment, a case where the game device of the present invention is applied to a mobile phone will be described. [First Embodiment] FIG. 1 is a diagram showing a network configuration of a mobile communication system according to the present invention. The mobile communication system 1 is connected to, for example, the public line network 2 and connected to the mobile phone dedicated network 3 including the relay switching center 7, the mobile switching centers 8a and 8b, and the center 9, and the corresponding mobile switching centers 8a and 8b. The base stations 4a to 4f having jurisdiction over the respective radio areas 5a to 5f and the mobile phone 6 are configured.

  In the cellular phone dedicated network 3, in order to smoothly connect a call to the cellular phone 6, the wireless area 5 a to 5 f where the cellular phone 6 is currently located is registered in the center 9.

  The outline of the operation of the cellular phone dedicated network 3 regarding this location registration is as follows. Each base station 4a-4f periodically wirelessly transmits a control signal including a unique base station ID code (identification information) in the radio areas 5a-5f having jurisdiction. The mobile phone 6 receives the control signal when not talking, that is, when waiting. Then, the base station ID code is detected from the received control signal and compared with the previously received base station ID code. If the two do not match, it is determined that the wireless area in the area has changed, and a location registration request is transmitted to the corresponding base station. In response to this, the mobile phone dedicated network 3 updates the location registration information of the corresponding mobile phone 6 registered in the center 9.

  In the present invention, the game content executed on the mobile phone 6 is controlled using a base station ID code included in a control signal periodically transmitted by radio from the base stations 4a to 4f.

  FIG. 2 is a block diagram showing a circuit configuration of the mobile phone 6 of FIG. This mobile phone 6 is compatible with a CDMA (Code Division Multiple Access) system.

A display driving circuit 73 and a display 74.

  The signal received by the antenna 61 is amplified and frequency-converted by the RF unit 62, and becomes a baseband signal by the carrier modulation / demodulation unit 63. Then, the spread modulation / demodulation unit 64 performs a correlation operation with the spread code, and necessary reception data is extracted. Digital audio data included in the received data is expanded by the speech codec unit 65 and output via the audio conversion circuit 66 and the speaker 67.

  On the other hand, the analog audio signal input from the microphone 68 is converted into digital audio data by the audio conversion circuit 66 and compressed by the speech codec unit 65. The compressed digital voice data and other transmission data are multiplexed and spread by the spread modulation / demodulation unit 64 and carrier modulated by the carrier modulation / demodulation unit 63. Then, after the RF unit 62 performs processing such as frequency conversion and amplification, the signal is transmitted from the antenna 61.

CPU (Central
Processing Unit 69 is a ROM (Read
In accordance with a program stored in the (Only Memory) 70, an ID code storage process (see FIG. 7) and a game process (see FIG. 8) described later are executed. The ROM 70 stores programs and data for controlling communication functions and game functions realized by the mobile phone 6. A RAM (Random access Memory) 71 temporarily stores programs and data.

  The key input unit 72 is an input device having a plurality of operation keys. The display drive circuit 73 includes a drive circuit for controlling the display 74, a display buffer, a CG (Character Generator), and the like. The display 74 is composed of an LCD (Liquid Crystal Display) and displays images and character data.

  FIG. 3 is a diagram showing a memory configuration of the RAM 71 in FIG. The RAM 71 has, for example, an ID code storage area 71a, a game data storage area 71b, and a work area 71c.

  The ID code storage area 71 a stores the base station ID code 80 extracted from the received control signal as the current position information of the mobile phone 6. The game data storage area 71b stores a game program and data read from the ROM 70, such as a character control table 81, an item control table 82, and a scenario control table 83, which will be described later. The work area 71c stores programs and data for realizing the communication function read from the ROM 70.

  FIG. 4 is a diagram showing a data structure of the character control table 81 stored in the RAM 71. The character control table 81 stores data necessary for determining an enemy character to battle when the player character operated by the user during the game battles with an enemy character (Enemy Character).

  The character control table 81 has, for example, a “base station ID code” column 81a and an “enemy character” column 81b. The “base station ID code” column 81a stores group information of base station ID codes. In this base station ID code group information, information on base station ID codes divided into a plurality of groups according to the following criteria is stored. For example, the group is classified according to the value of a part of the base station ID code, such as the value of the lower 3 bits of the base station ID code being “001”. In addition, the calculation is performed using the value of the base station ID code, and the group is divided according to the value of the solution. The “enemy character” column 81b stores the types of enemy characters.

  When determining an enemy character to fight against, the character control table 81 first identifies the group to which the base station ID code 80 stored in the ID code storage area 71a belongs. Then, an enemy character to be battled is determined from one or more enemy characters associated with this group.

  FIG. 5 is a diagram showing a data structure of the item control table 82 stored in the RAM 71. The item control table 82 stores data necessary for determining an item to be displayed when a new item is displayed during the game.

  The item control table 82 includes, for example, a “base station ID code” column 82a and an “item” column 82b. The “base station ID code” column 82a stores group information of base station ID codes. In this base station ID code group information, information on base station ID codes divided into a plurality of groups according to the following criteria is stored. For example, the group is classified according to the value of a part of the base station ID code, such as the value of the lower 3 bits of the base station ID code being “001”. In addition, the calculation is performed using the value of the base station ID code, and the group is divided according to the value of the solution. The “item” column 82b stores the type of item.

  When determining an item to be newly displayed, first, in the item control table 82, a group to which the base station ID code 80 stored in the ID code storage area 71a belongs is specified. Then, an item to be displayed is determined from one or more items associated with this group.

  FIG. 6 is a diagram showing the data structure of the scenario control table 83 stored in the RAM 71. The scenario control table 83 stores data necessary for determining a branch destination scenario when the game scenario progress is branched during the game.

  The scenario control table 83 includes, for example, a “scenario branch point” field 83a, a “base station ID code” field 83b, and a “branch destination scenario” field 83c. The “scenario branch point” column 83a stores branch point information for branching the game scenario progress. The “base station ID code” column 83b stores group information of base station ID codes. In this base station ID code group information, information on base station ID codes divided into a plurality of groups according to the following criteria is stored. For example, the group is classified according to the value of a part of the base station ID code, such as the value of the lower 3 bits of the base station ID code being “001”. In addition, the calculation is performed using the value of the base station ID code, and the group is divided according to the value of the solution. The “branch destination scenario” field 83c stores the branch destination scenario ID (Identification) information.

  When determining a branch destination scenario, in the scenario control table 83, first, the branch point of the scenario is determined, and the group to which the base station ID code 80 stored in the ID code storage area 71a belongs is specified. Then, the scenario associated with this group is determined as the branch destination scenario.

  The group classification of the base station ID code stored in the “base station ID code” column 81a, 82a, 83b of each control table 81, 82, 83 may be as shown below. For example, group information of a base station ID code composed of at least one base station ID code is stored.

  Next, the operation of the mobile phone 6 in the first embodiment will be specifically described. Among the controls performed by the mobile phone 6, there is one in which a circuit other than the CPU 69 performs control in cooperation with the CPU 69. For convenience of explanation, the control related to the CPU 69 will be described below assuming that the CPU 69 directly controls the control. In addition, programs and data necessary for realizing the communication function and the game function are sequentially transferred from the ROM 70 to the RAM 71 in accordance with the progress of processing according to instructions from the CPU 69. However, in the following description, in order to facilitate understanding of the invention, detailed description regarding reading of data from the ROM 70 and transfer to the RAM 71 is omitted.

  FIG. 7 is a flowchart illustrating an example of ID code storage processing. The ID code storage process is periodically executed based on the interrupt request when the mobile phone 6 is not in a call, that is, when waiting. When the process is started, first, a control signal that is periodically transmitted from a base station that has jurisdiction over the wireless area in which the mobile phone 6 is located is received (step S101). Next, it is determined whether or not control signals have been received from a plurality of base stations (step S102). A case where control signals are received from a plurality of base stations is a case where the mobile phone 6 is located at a location where the wireless areas overlap each other.

  If the control signal is received only from any one of the base stations, the base station ID code is detected from the received control signal (step S103). When control signals are received from a plurality of base stations, the reception level of each control signal is measured (step S104), and the control signal having the highest reception level is specified. Then, the base station ID code is detected from the specified control signal (step S105).

  Next, the CPU 69 compares the base station ID code 80 previously received and stored in the ID code storage area 71a with the base station ID code detected in step S103 or step S105 (step S106). Then, it is determined whether or not the comparison results are inconsistent (step S107). Only when they do not match, the base station ID code detected this time is stored in the ID code storage area 71a as new current position information of the mobile phone 6 (step S108). By executing this ID code storage process, the base station ID code, which is the current position information of the mobile phone 6, is stored in the ID code storage area 71a.

  FIG. 8 is a flowchart illustrating an example of the game process. The game processing is a case where the mobile phone 6 is in a standby state, and the user operates the key input unit 72 and a game start request is made based on an operation signal input from the key input unit 72. If executed. The CPU 69 starts the game according to the game program and performs control related to the progress of the game (step S201). For example, in response to an operation input from the user, the player character displayed on the display 74 is moved or the display image is switched.

  Next, in the middle of the control relating to the progress of the game, it is determined whether or not processing to be executed using the base station ID code has occurred (step S202). The process executed using the base station ID code includes, for example, an encounter process for determining an enemy character to fight against, an item generation process for generating a new item, a scenario branch process for controlling a scenario branch, and the like. .

  In the case of the encounter process, for example, it is determined whether or not this process has occurred as follows. That is, in the course of the game, when the player character is moving on the game map, a process of generating a battle with the enemy character based on a predetermined probability value is executed. When a battle with an enemy character occurs by this process, it is determined that the execution of the encounter process has occurred.

  In the case of item generation processing, for example, it is determined whether or not this processing has occurred as follows. That is, in the course of the game, the item generation process is executed when the player character wins a battle with an enemy character or when an operation instruction to open a treasure box (item box) placed on the game field is given. It is determined that it has occurred.

  In the case of scenario branch processing, for example, it is determined whether or not this processing has occurred as follows. That is, it is determined that the scenario branch process has been executed when the game has progressed to a branch point that branches a preset scenario progress in the course of the game. In addition, when the various parameter values indicating the fighting power of the subject character associated with the subject character satisfy a specific condition, such as when the scenario branch process is performed It is determined that execution has occurred.

  If the process requiring the base station ID code, that is, none of the encounter process, the item generation process, and the scenario branch process has occurred, the process proceeds to step S214. On the other hand, when execution of any one of the encounter process, the item generation process, and the scenario branch process occurs, first, the base station ID code 80 stored in the ID code storage area 71a is acquired (step S203). . Next, the type of processing that has occurred is specified (step S204).

  When the generated process is an encounter process (step S205), first, the group to which the base station ID code 80 acquired in step S203 belongs is specified with reference to the character control table 81. Next, the type of enemy character to be battled from one or more enemy characters associated with this group is determined using, for example, a random number (step S206). And after acquiring the image data and ability data of the determined enemy character, and displaying on the display 74 (step S207), it transfers to step S214.

  FIG. 9 is a diagram showing an example of a character image displayed on the display 74 in step S207 of the game process of FIG. The display example shown in FIG. 9A is an example of an opponent when the mobile phone 6 is located in the wireless area of a base station having a base station ID code belonging to group A in the character control table 81 shown in FIG. It is the image of enemy character EC1 displayed. Further, the display example shown in FIG. 9B is displayed as an opponent when the user is in the wireless area of the base station having the base station ID code belonging to group C in the character control table 81 shown in FIG. This is an image of the enemy character EC8.

  The display example shown in FIG. 9 (a) and the display example shown in FIG. 9 (b) are cases where the current position of the user who is playing the game is different and all other conditions are the same. In this way, the enemy characters that fight against the area where the user is playing the game can be made different as the enemy character 91 shown in FIG. 9A and the enemy character 92 shown in FIG. 9B. .

  By this encounter processing, it is possible to determine an enemy character to fight against on the condition of the current position of the mobile phone 6, that is, the area where the user is playing the game. Therefore, it is possible to fight different enemy characters depending on the area where the mobile phone 6 is playing the game. As a result, it is possible to enhance the fun of the game, such as playing a game in another area and enjoying a battle with a new enemy character.

  Also, consider a game in which when an enemy character that has fought is defeated, that enemy character can be used as its own character. In this case, since the enemy characters appearing according to the region are different, it is interesting to move to various regions and play the game in order to obtain various characters. Also, in order to obtain various characters, information exchange with people in different regions is not only enhanced, but the usefulness as a communication tool is also enhanced. Further, for example, when the current position of the mobile phone 6 is in the Tohoku region, the appearance control of the character utilizing the locality can be performed by causing “Namahage” to appear as an enemy character.

  On the other hand, if the generated process is an item generation process (step S208), first, the group to which the base station ID code 80 acquired in step S203 belongs is identified with reference to the item control table 82. Next, the type of an item generated from one or more items associated with this group is determined using, for example, a random number (step S209). And after acquiring the image data and performance data of the determined item, and displaying on the display 74 (step S210), it transfers to step S214.

  By this item generation process, the item to be generated can be determined on the condition of the current position of the mobile phone 6, that is, the area where the user is playing the game. Accordingly, different items are generated depending on the area where the mobile phone 6 is playing a game. As a result, since the items that can be acquired differ depending on the region, it is possible to enhance the interest of the game, such as moving to various regions and playing the game in order to obtain various items. In addition, usefulness as a communication tool is increased, such as exchanging information with people in different regions to obtain special items. It is also possible to control the generation of items that take advantage of regional characteristics.

  On the other hand, when the generated process is a scenario branch process (step S211), the scenario branch point is first determined with reference to the scenario control table 83. Next, the group to which the base station ID code 80 acquired in step S203 belongs is specified. Then, a branch destination scenario is determined according to the scenario ID information associated with this group (step S212). Next, image data corresponding to the determined scenario is acquired and displayed on the display 74 (step S213), and then the process proceeds to step S214.

  By this scenario branching process, the branching control of the scenario can be performed using the current position of the mobile phone 6, that is, the region where the user is playing the game as a branching condition. Therefore, the scenario branch of the game can be varied depending on the area where the mobile phone 6 is playing the game. As a result, it is possible to enhance the fun of the game, such as moving to various regions and playing games in order to enjoy various scenarios. Also, if the area where the game is played is changed, the same game can be enjoyed many times. Furthermore, in order to enjoy various scenario branches, it will be useful as a communication tool, such as exchanging information with people in different regions. It is also possible to perform branch control of scenarios that make use of regional characteristics.

  In step S214, it is determined whether or not a game end condition is satisfied (step S214). The end condition is, for example, a case where a game end request is made based on an operation signal input from the key input unit 72, or a case where the mobile phone 6 receives an incoming call. If the end condition is not satisfied, the process returns to step S201. If the end condition is satisfied, the game process is terminated after performing a process such as saving the game progress data.

  According to the first embodiment, the mobile phone 6 waits for a control signal periodically transmitted from a base station having jurisdiction over the wireless area where the mobile phone 6 is currently located among a plurality of base stations. Receive. The base station ID code is extracted from the received control signal and stored in the ID code storage area 71a. Then, in the course of the game, the game is advanced according to the stored base station ID code, and an image corresponding to the progress of the game is displayed on the display 74.

  Therefore, the game contents such as the scenario branch in the game and the displayed character image and item image can be varied according to the area where the user is playing the game. The position information for making the game contents different uses a base station ID code (identification signal) periodically transmitted from the base station in order to register the position of the mobile phone in the mobile phone system. Therefore, the game content can be changed according to the current position information of the user.

  In addition, since the base station ID code periodically transmitted from the base station is used as the location information in the mobile phone system in order to register the location of the mobile phone in the mobile phone system, the following advantages are also obtained.

  That is, normally, in a mobile phone, at the time of a call or communication, it is necessary to stop the game function being executed and execute processing related to the communication function. For this reason, when using base station identification information acquired in response to an incoming call or outgoing call, the base station identification information read from the memory for controlling the progress in the course of the game is not received or called. It is only the position information acquired at the specified timing. Therefore, this position information is only position information of a place where the user has made a call or communication in the past.

  However, according to the first embodiment, the control signal including the base station ID code is periodically transmitted from the base station and sequentially received when the mobile phone 6 is on standby. Therefore, in the progress of the game, the game content can be changed according to the position information indicating the current position of the user. In addition, since the base station ID code is acquired when the mobile phone 6 is on standby, it is possible to acquire the user's location information without performing a call or communication between the called side and the calling side.

  In the first embodiment, the program and data relating to the game are stored in the ROM 70 in advance. However, any game program and data may be downloaded from the base station to the mobile phone. . In this case, an EEPROM (Electrically Erasable Programmable ROM) is provided, and downloaded game programs and data are stored in the EEPROM. With such a configuration, the mobile phone 6 can download and use programs and data relating to the game from the base station. Therefore, it becomes possible to electronically distribute and sell programs and data related to games as software products independently of the apparatus.

  Next, a second embodiment will be described. The second embodiment is different from the first embodiment in the following points. That is, in the first embodiment, the case where the present invention is applied to a mobile phone has been described. In the second embodiment, in a mobile communication system such as a mobile phone, a function for receiving a control signal wirelessly transmitted from a base station and a function for extracting a base station ID code from the received control signal are provided. A case where the present invention is applied to a portable game machine having the above will be described.

  Therefore, in the second embodiment, only the hardware configuration to which the present invention is applied is different, and the other table data configuration, ID code storage processing, and game processing procedures are the same as those in the first embodiment. It is. About the same structure and process as 1st Embodiment, the code | symbol same as 1st Embodiment is attached | subjected and the overlapping description is abbreviate | omitted. Only differences from the first embodiment will be described below.

  FIG. 10 is a block diagram illustrating a circuit configuration of the portable game machine according to the second embodiment. This portable game machine 100 extracts a base station ID code from the received control signal and a function for receiving a control signal transmitted from a base station constituting a mobile communication system of a mobile phone (CDMA system). With functions.

  The portable game machine 100 includes an antenna 61, an RF unit 62, a carrier modulation / demodulation unit 63, a diffusion modulation / demodulation unit 64, a CPU 69, a RAM 71, a display drive circuit 73 and a display 74, a ROM 101, a key input unit 102, an interface shown in FIG. A circuit 103 and a ROM card 104 are provided.

  The ROM 101 stores an operation system that controls each unit of the portable game machine 100. The key input unit 102 is an input device that includes direction keys and a plurality of operation buttons. The interface circuit 103 is configured such that the ROM card 104 can be detachably attached.

  The ROM card 104 stores a program and data for controlling a game realized by the portable game machine 100. In addition, a program and data necessary for realizing a function for receiving a control signal wirelessly transmitted from the base station are stored. Furthermore, the ROM card 104 also stores programs and data necessary for realizing the function of extracting the base station ID code from the received control signal. Programs and data recorded in the ROM card 104 are read out as necessary in accordance with instructions from the CPU 69 and transferred to the RAM 71. This ROM card 104 can be easily distributed and sold as a software product independently of the apparatus.

  In the portable game machine 100 having such a configuration, the ID code storing process (see FIG. 7) and the game process (see FIG. 8) described in the first embodiment are executed. However, unlike the mobile phone 6 described in the first embodiment, the portable game machine 100 does not have a call function. Therefore, the ID code storage process (see FIG. 7) is based on a predetermined interrupt request during a period in which the power is turned on in the portable game machine 100 or a period in which the game process is being executed in the portable game machine 100. To be executed regularly.

  With such a control configuration, game control similar to that of the mobile phone 1 described in the first embodiment can be realized in the portable game machine 100 as well. That is, the portable game machine 100 receives a control signal that is periodically wirelessly transmitted from a base station that has jurisdiction over the wireless area where the portable game machine 100 is currently located among a plurality of base stations. The base station ID code is extracted from the received control signal and stored in the ID code storage area 71a. Then, in the course of the game, the game is advanced according to the stored base station ID code, and an image corresponding to the progress of the game is displayed on the display 74.
