Next, the operation of the mobile phone 6 according to the first embodiment will be specifically described. Some of the controls performed by the mobile phone 6 are performed by circuits other than the CPU 69 in cooperation with the CPU 69. For convenience of explanation, hereinafter, the control related to the CPU 69
9 will be described assuming that it is directly controlled.
Further, programs and data necessary for realizing the communication function and the game function are sequentially stored in the ROM 70 and the RAM 71 in accordance with the progress of the processing in accordance with the instruction from the CPU 69.
Is forwarded to However, in the following description, a detailed description of reading data from the ROM 70 and transferring the data to the RAM 71 will be omitted to facilitate understanding of the present invention.

FIG. 7 is a flowchart showing an example of the ID code storing process. The ID code storage processing is performed when the mobile phone 6 is not in a call, that is, when the mobile phone 6 is in a standby state.
It is executed periodically based on an interrupt request. When the process is started, first, a control signal periodically transmitted from a base station that controls a wireless area where the mobile phone 6 is located is received (step S101). Next, it is determined whether control signals have been received from a plurality of base stations (step S102). The case where the control signals are received from a plurality of base stations is the case where the mobile phone 6 is located in a place where the wireless areas overlap with each other.

If the control signal has been received from only one of the base stations, the base station ID code is detected from the received control signal (step S103). When control signals have been 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 S10).
5).

Next, the CPU 69 receives the previously received I
Base station ID code 8 stored in D code storage area 71a
0 is compared with the base station ID code detected in step S103 or S105 (step S10).
6). Then, it is determined whether or not the comparison result is inconsistent (step S107). Only if there is a mismatch,
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 the ID code storage processing, the ID code storage area 71a stores
A base station ID code, which is current position information of the mobile phone 6, is stored.

FIG. 8 is a flowchart showing an example of the game process. The game process is performed when the mobile phone 6 is in a standby mode, and when the user operates the key input unit 72.
To be executed when a game start request is made based on an operation signal input from the key input unit 72. The CPU 69 starts the game according to the game program, and controls the progress of the game (step S201). For example, the player character moves on the display 74 in response to an operation input from the user, or switches the display image.

Next, during the control of the progress of the game, it is determined whether or not a process to be executed using the base station ID code has occurred (step S202). The processing executed using the base station ID code is, for example,
Encounter processing to determine enemy characters to fight,
Item generation processing for generating a new item, scenario branch processing for controlling scenario branching, and the like.

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

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

In the case of the scenario branch processing, it is determined whether or not this processing has occurred, for example, as follows. That is, in the course of the game progress, if the game has progressed to a preset branch point where the scenario progresses, it is determined that the execution of the scenario branch processing has occurred. Further, when various parameter values indicating the fighting power of the own character associated with the own character satisfy a specific condition, such as when the specific condition set in advance during the game is satisfied, the scenario branching process is performed. It is determined that execution has occurred.

If the processing requiring the base station ID code, that is, none of the encounter processing, the item generation processing, and the scenario branch processing has occurred, the process proceeds to step S214. On the other hand, when execution of any of the encounter processing, the item generation processing, and the scenario branch processing occurs, first, the ID code storage area 7
The base station ID code 80 stored in 1a is obtained (step S203). Next, the type of the generated processing is specified (step S204).

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

FIG. 9 shows a step S2 of the game processing of FIG.
FIG. 17 is a diagram illustrating an example of a character image displayed on a display 74 at 07. The display example shown in FIG. 9A is the character control table 81 shown in FIG.
This is an image of the enemy character EC1 displayed as an opponent when the mobile phone 6 is located in the wireless area of the base station having the base station ID code belonging to the group A. The display example shown in FIG. 9B is displayed as an opponent in the character control table 81 shown in FIG. 4 when the user is located in the wireless area of the base station having the base station ID code belonging to the group C. This is an image of the enemy character EC8.

The display example shown in FIG. 9A and the display example shown in FIG. 9B are cases where only the current position of the user playing the game is different and all other conditions are the same. In this way, the enemy characters that the user battles according to the area in which the game is played are changed to the enemy characters 91 shown in FIG.
And the enemy character 92 shown in FIG. 9B.

With this encounter process, it is possible to determine an enemy character to compete with, based on 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 game is played on the mobile phone 6. As a result, it is possible to enhance the interest 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 a defeated enemy character can use the enemy character as its own character. In this case, since the enemy character that appears differs depending on the region, it is interesting to move to various regions and play a game in order to obtain various characters. In addition, in order to obtain various characters, information is exchanged with people in different areas. This not only enhances the interest of the game, but also enhances its usefulness as a communication tool. In addition, for example, when the current position of the mobile phone 6 is in the Tohoku region, appearance control of a character taking advantage of locality can be performed by causing “Namahage” to appear as an enemy character.

On the other hand, when the generated processing is the item generation processing (step S208), first, the group to which the base station ID code 80 obtained in step S203 belongs is specified with reference to the item control table 82. Then
The type of item generated from one or more items associated with this group is determined using, for example, a random number (step S209). Then, image data and performance data of the determined item are obtained and
4 (Step S210), and then Step S21
Move to 4.

By this item generation processing, 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. Therefore, different items are generated depending on the region where the game is played on the mobile phone 6. As a result, since the items that can be obtained differ depending on the region, it is possible to enhance the interest of the game, such as moving to various regions to play the game in order to obtain various items. In addition, in order to obtain special items, information is exchanged with people in different regions, and the usefulness as a communication tool is enhanced. In addition, it is possible to control the generation of items taking advantage of regional characteristics.

On the other hand, if the generated processing is the scenario branch processing (step S211), first, the scenario control table 83 is referred to to determine the branch point of the scenario. Next, the group to which the base station ID code 80 obtained in step S203 belongs is specified. Then, the branch destination scenario is determined according to the scenario ID information associated with this group (step S212). Next, after acquiring the image data according to the determined scenario and displaying it on the display 74 (step S213),
It moves to step S214.

With this scenario branching process, the branching of the scenario can be controlled using the current position of the mobile phone 6, that is, the area where the user is playing a game as a branching condition. Therefore, the game scenario branch can be made different depending on the region where the mobile phone 6 is playing the game. As a result, it is possible to enhance the interest of the game, such as moving to various regions to play the game in order to enjoy various scenarios. Also, if the region where the game is played is changed, the same game can be enjoyed many times. Furthermore, the utility as a communication tool is enhanced, such as exchanging information with people in different areas to enjoy various scenario branches. In addition, it is possible to perform branch control of a scenario taking advantage of regional characteristics.

In step S214, it is determined whether or not a game ending condition is satisfied (step S21).
4). 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, a case where an incoming call arrives at the mobile phone 6, or the like.
If the termination condition has not been satisfied, step S20
Return to 1. When the termination condition is satisfied, the game processing is terminated after performing processing such as saving the game progress data.

According to the first embodiment, the portable telephone 6
Receives a control signal that is periodically wirelessly transmitted from a plurality of base stations wirelessly transmitted from a base station that is in charge of a wireless area where the mobile phone 6 is currently located. Then, 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 progress, 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 7.
4 is displayed.

Therefore, it is possible to vary the game content such as the scenario branch during the game and the displayed character image and item image depending on the region where the user is playing the game. Further, as the position information for making the contents of the game different, a base station ID code (identification signal) periodically transmitted from the base station to register the position of the mobile phone in the mobile phone system is used.
Therefore, the game content can be changed according to the current position information of the user.

Also, the following advantage is obtained by using a base station ID code periodically transmitted from the base station to register the location of the mobile phone in the mobile phone system as the location information. Also have.

That is, normally, in a mobile phone, during a call or communication, it is necessary to stop the game function being executed and execute processing relating to the communication function. Therefore, when the base station identification information obtained in response to an incoming call or outgoing call is used, the base station identifying information read out from the memory for controlling the progress of the game during the progress of the game is used when the incoming call or outgoing call is made. It is only the location information obtained at the timing of the change. Therefore, this position information is only the position information of the place where the user 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 is sequentially received when the mobile phone 6 waits. Therefore, in the course of 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, the location information of the user can be acquired without performing a telephone call or communication between the called side and the calling side.

In the first embodiment, the programs and data relating to the game are stored in the ROM 70 in advance, but any game program or data is downloaded from the base station to the mobile phone. You may. In this case, an EEPROM (Electrically E
rasable Programmable ROM)
The OM stores the downloaded game program and data. With such a configuration, the mobile phone 6 can download and use programs and data relating to the game from the base station. Therefore,
Games and programs related to games can be electronically distributed and sold as software products independently of the device.

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)
It is assumed that the game is periodically executed based on a predetermined interrupt request while the power is turned on in the portable game machine 100 or the game processing is being executed in the portable game machine 100.

With such a control configuration, the same game control as that of the mobile phone 1 described in the first embodiment can be realized in the portable game machine 100. That is, the portable game device 100 receives a control signal that is periodically wirelessly transmitted from a base station that is in charge of a wireless area where the portable game device 100 is currently located, among a plurality of base stations. Then, 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 progress 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, in the portable game machine 100, the game content such as the scenario branch during the game and the displayed character image and item image can be made different depending on the region where the user is playing the game.
Further, as the position information for making the contents of the game different, a base station ID code (identification signal) periodically transmitted from the base station to register the position of the mobile phone in the mobile phone system is used. Therefore, the game content can be changed according to the current position information of the user.

In the second embodiment, programs and data for realizing the present invention are stored in the ROM card 104.
And the ROM card 104 was used as a recording medium. However, the recording medium is not limited to the ROM card, but may be another computer-readable magnetic or optical recording medium or a semiconductor memory.

In the second embodiment, in order to obtain location information in the portable game machine 100, network equipment of the portable telephone system is used. But P
Network equipment of a mobile communication system such as an HS or a pager may be used. In addition, the portable game machine 100
For example, a facility provided solely for the purpose of acquiring location information may be used. The equipment in this case is
A plurality of transmitters for periodically transmitting wirelessly a position identification information or a control signal including the position identification information may be prepared in an area under its own jurisdiction, and these transmission apparatuses may be appropriately arranged in consideration of each other's jurisdiction. .

As described above, the present invention has been specifically described based on the first and second embodiments. However, the present invention is not limited to the above-described embodiment, and is within the scope of the present invention. Of course, it can be changed as appropriate.

For example, in the first embodiment, a case has been described in which the present invention is applied to a mobile phone. However, the present invention is not limited to a mobile phone, but is applied to a PHS, a pager, or the like. Is also good. In the second embodiment, the case where the present invention is applied to a portable game machine has been described. However, a function for receiving a control signal wirelessly transmitted from a base station in a mobile communication system,
The present invention is applicable to any electronic device having a function of extracting a base station ID code from a received control signal.
For example, the present invention may be applied to an electronic organizer, a portable information terminal, and a car navigation.

Further, in the first and second embodiments, the game content is made different depending on only the base station ID code (identification information). However, the game content may be made different using other information in addition to the base station ID code. For example, a case is considered where the mobile phone 6 or the portable game machine 100 described in the first or second embodiment further has a time clock function for measuring the current time. In this case, a configuration may be employed in which the game content such as a scenario branch during the game or a displayed character image and item image is changed according to the base station ID code and the current time information obtained by the time counting function.
