Next, the operation of the mobile phone 6 according to the first embodiment will be specifically described. In the control performed by the mobile phone 6, a circuit other than the CPU 69 may perform the control in cooperation with the CPU 69. For convenience of explanation,
In the following description, the control related to the CPU 69 is the CPU
The description will be made assuming that 69 directly controls. Further, 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 the processing in accordance with an instruction from the CPU 69. 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. 8 is a flowchart showing an example of the ID code storing process. This ID code storage processing is for a case where the mobile phone 6 intermittently receives a control signal periodically wirelessly transmitted from the base station when the mobile phone 6 is in the standby period. For example, a base station may have several hundred [m
/ sec]. The ID code storing process is sequentially executed based on an interrupt request to receive a control signal transmitted from the base station when the mobile phone 6 is not in a call, that is, in a standby state.

When the processing is started, first, the CPU 69
Receives a control signal that is periodically wirelessly transmitted from a base station that controls the wireless area where the mobile phone 6 is located (step S101). Next, the radio wave intensity level of the received control signal is measured (step S102). Then, the processing of steps S101 and S102 is repeated m (m is a natural number) times (step S103), and the received m
An average value of the radio field intensity levels is calculated for each of the control signals (step S104). Next, it is determined whether or not the calculated average value of the radio wave intensity levels is equal to or greater than a predetermined value (step S105).

If the average of the radio field intensity levels has not reached the predetermined value, the CPU 69 determines that the mobile station has shifted to the wireless area of another base station, and executes a base station search process (step S106). Then, after performing the setting for intermittently receiving the control signal from the searched base station (step S
107), and returns to step S101.

On the other hand, if it is determined in step S105 that the average value of the radio wave intensity levels is equal to or greater than the predetermined value, m
The control signal received the third time is demodulated to detect the base station ID code (step S108). Next, the CPU 69
Compares the base station ID code 80 previously detected and stored in the ID code storage area 71a with the base station ID code detected in step S108 (step S1).
09). Then, it is determined whether or not the comparison result is inconsistent (step S110). Only when there is a mismatch, a location registration request is transmitted to the base station to cause the mobile phone dedicated network 3 to perform location registration processing. Then, the base station ID code detected in step S108 is
ID code storage area 71a as new current position information of
(Step S111).

By executing the ID code storing process, the base station ID code is stored in the ID code storage area 71a as the current position information of the mobile phone 6. Note that the ID code storage process is performed in a game process described later (FIG. 9).
) Is executed sequentially based on the interrupt request.

FIG. 9 is a flowchart showing an example of the game process. The game process is executed when the mobile phone 6 is in the standby period and the user operates the key input unit 72 to input a game start request.
The CPU 69 stores the game data storage area 71 of the RAM 71
The game is started according to the game program 85 stored in b, and control relating to the progress of the game is performed (step S201). For example, in response to an operation input from a user, a process of moving the own character displayed on the display 74 or controlling a battle with an enemy character is performed.

Next, it is determined whether or not a process executed using the base station ID code has occurred during the control period for the progress of the game (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.

The determination as to whether or not an encounter process has occurred is as follows. That is, while the own character is moving on the game map, an arithmetic process for causing a battle with an enemy character based on a predetermined probability value is performed. When it is calculated by this calculation process that a battle with the enemy character has occurred, it is determined that execution of the encounter process has occurred.

The determination as to whether or not the item generation processing has occurred is as follows. That is, it is determined that the execution of the item generation processing has occurred when the own character has won the battle with the enemy character or when an operation instruction to open a treasure box (item box) arranged on the game field has been given. .

The determination as to whether or not the scenario branching process has occurred is as follows. That is, in the course of the game progress, when the game has progressed to a preset branch point of the scenario, it is determined that the execution of the scenario branch processing has occurred. Further, when a scenario branch condition set in advance during the game is satisfied, such as when various parameter values indicating the battle ability of the own character associated with the own character satisfy a specific condition, the scenario branch processing is performed. It is determined that execution has occurred.

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

If the generated process is an encounter process (step S205), first, the ID code section to which the base station ID code 80 obtained in step S203 belongs is specified by referring to the character control table 81 (see FIG. 4). I do. Next, from one or more enemy characters associated with the specified ID code segment, the type of the enemy character to be played is determined using, for example, a random number (step S206). Then, the image data and control data of the determined enemy character are read from the work area 71c of the ROM 70 or the RAM 71 and displayed on the display 74 (step S207), and then the process proceeds to step S214.

FIGS. 10 (a) and 10 (b) correspond to FIG.
FIG. 7 is a diagram showing an example of a character image displayed on a display 74 by the game processing of FIG. FIG. 10A shows a screen display when the mobile phone 6 is located in the wireless area of the base station A having the base station ID code whose ID code classification belongs to “00” in the character control table 81 shown in FIG. This is an example. When the ID code division is “00”, there are three enemy characters that may be displayed as opponents, as shown in FIG. 4, EC1, EC2, and EC3. And these three enemy characters EC1, EC
2. The character image corresponding to EC3 is shown in FIG.
In character images 91 (EC1) and 92 (EC
2), 93 (EC3). Therefore, if the mobile station is located in the wireless area of the base station A,
One of the three screen display examples shown in FIG. 10A will be displayed on the display 74.

FIG. 10B shows the character control table 81 shown in FIG.
This is a screen display example when the mobile phone 6 is located in the wireless area of the base station B having the base station ID code belonging to “1”. When the ID code division is “01”, there are two enemy characters EC3 and EC4 that may be displayed as opponents as shown in FIG. The character images corresponding to these two enemy characters EC3 and EC4 are the character images 93 (EC) in FIG.
3), 94 (EC4). Therefore, if the mobile station is located in the wireless area of the base station B,
One of the two screen display examples shown in FIG. 10B will be displayed on the display 74.

In the screen display examples shown in FIGS. 10A and 10B, the character images 91 and 92,
Characters displayed at the lower portions of 93 and 94 are control data of the enemy character. “Name” indicates the name of the enemy character. “LV” is the level of the enemy character, and is a numerical value indicating a measure of strength (the larger the numerical value, the stronger). “HP (Hit Point)” indicates a physical strength value of the enemy character. Character image data and control data are stored in the ROM 70, and are stored in the ROM 70 as necessary.
The data is transferred to the work area 71c of the AM 71. And C
The data is transferred to the display drive circuit 73 in response to a display command from the PU 69 and displayed on the display 74.

The screen display example shown in FIG. 10A and the screen display example shown in FIG. 10B are cases where only the current position of the user playing the game is different and all other conditions are the same. . In this manner, the enemy characters that compete against each other in accordance with the region where the user is playing the game can be different as shown in FIGS. 10A and 10B.

By 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.

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, information on which characters can be obtained in which regions is exchanged with people in different regions. For example, not only does the game become more interesting, but it also becomes more useful as a communication tool. . Further, for example, when the current position of the mobile phone 6 is in the Tohoku region, if a monster “Namahage” transmitted to the Tohoku region is caused to appear as an enemy character, the appearance control of the character taking advantage of the locality may be performed. it can.

On the other hand, if the processing that has occurred is an item generation processing (step S208), the ID code classification to which the base station ID code 80 obtained in step S203 belongs first with reference to the item control table 82 (see FIG. 5). To identify. Next, from one or more items associated with the specified ID code section, the type of item to be generated is determined using, for example, a random number (Step S).
209). Then, the image data and control data of the determined item are read from the work area 71c of the ROM 70 or the RAM 71 and displayed on the display 74 (step S210), and then the process proceeds to step S214.

FIGS. 11A and 11B show FIG.
It is a figure which shows an example of the item image displayed on the display 74 by the game process of FIG. FIG.
21 is a screen display example when the mobile phone 6 is located in the wireless area of the base station A having the base station ID code whose ID code category belongs to “00” in the item control table 82 shown in FIG. When the ID code division is “00”, the only item that may occur as shown in FIG. 5 is R1. The item image corresponding to the item R1 is the item image 95 (R1) in FIG. Therefore, when the item is located in the wireless area of the base station A, the screen display example shown in FIG.

FIG. 11B shows the item control table 82 shown in FIG.
3 is a screen display example when the mobile phone 6 is located in the wireless area of the base station C having the base station ID code belonging to “3”. When the ID code classification is “03”, there are two items that may occur as shown in FIG. 5, R3 and R4. The item images corresponding to these two items R3 and R4 are the item images 96 (R3) and 97 (R4) in FIG. 11B. Therefore,
When the item is located in the wireless area of the base station C, one of the two screen display examples shown in FIG. 11B is displayed on the display 74 when an item occurs.

In the screen display examples shown in FIGS. 11A and 11B, the item images 95, 96, 9
The characters displayed at the bottom of each item 7 are item control data. “Name” indicates the name of the item. "Type" indicates the type of item. The item image data and the control data are stored in the ROM 70, and are transferred to the work area 71c of the RAM 71 as needed. The data is transferred to the display drive circuit 73 in response to a display command from the CPU 69 and is displayed on the display 74.

The screen display example shown in FIG. 11A and the screen display example shown in FIG. 11B 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 items that occur depending on the region where the user is playing the game can be different as shown in FIGS. 11A and 11B.

According to the 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 a 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, the information as to which items can be obtained in which region 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 branch point No. is referred to by referring to the scenario control table 83 (see FIG. 6). Is determined. Next, the determined branch point N
o. From the ID code section corresponding to
Specify the ID code section to which the base station ID code 80 obtained in the above belongs. Then, the branch destination scenario is determined according to the branch scenario information associated with the specified ID code section (step S212). Next, the branch scenario data corresponding to the determined branch scenario information is read out from the scenario data 86 of the ROM 70, and read from the RAM.
The data is transferred to the work area 71c. Then, the game progress is controlled based on the branch scenario data transferred to the work area 71c (step S213).

FIGS. 12A and 12B show FIG.
FIG. 8 is a schematic diagram showing a scenario transition example of a game scenario that is controlled to be branched by the game processing of FIG. FIG.
It is a figure which shows the scenario transition when the mobile telephone 6 continues to be in the wireless area of the base station A which has the base station ID code whose D code classification belongs to "00". When the mobile station continues to be located in the wireless area of the base station A, the branch destination scenarios at the branch points 1, 2, and 3 in the scenario control table 83 in FIG. That is, in branch point 1, scenario a1, branch point 2
In scenario b1, scenario c1 at branch point 3. Therefore, when the mobile station continues to be located in the wireless area of the base station A, the scenario transitions to a scenario s0, a scenario a1, a scenario b1, and a scenario c1, as shown in FIG.

FIG. 12B shows a radio area of the base station A whose ID code division is “00”, a radio area of the base station D whose ID code division is “3E”, and an ID code division of “3E”. FIG. 9 is a diagram illustrating a scenario transition when the mobile phone 6 sequentially moves to and from the wireless area of the base station E that is “FF”. The movement timing to another wireless area is as shown in FIG. In this case, each branch point 1 in the scenario control table 83 in FIG.
In scenarios 2 and 3, the branch destination scenarios are as follows, respectively. That is, since the branch point 1 is located in the wireless area of the base station A whose ID code division is “00”, the branch destination scenario is the scenario a1. Since the branch point 2 is located in the wireless area of the base station D whose ID code division is “3E”, the branch destination scenario is the scenario b1. Since the branch point 3 is located in the wireless area of the base station E whose ID code division is “FF”, the branch destination scenario is the scenario c2.

Therefore, the scenario transition is performed as shown in FIG.
As shown in (b), a transition is made to scenario s0, scenario a1, scenario b1, and scenario c2. As described above, the branch of the game scenario can be made different as shown in FIGS. 12A and 12B according to the region where the user is playing the game.

By 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 the 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.

At step S214, it is determined whether or not the 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 end condition is satisfied, the game processing is ended after performing save processing such as saving the game progress data.

In the game process, the progress of the game is controlled according to only one base station ID code 80 stored in the ID code storage area 71a for identifying the area where the mobile phone 6 is currently located. The control of the game progress is, specifically, determination of an enemy character to compete, determination of an item to be generated, and branch control of a game scenario. However, as a configuration in which a plurality of base station ID codes can be stored in the ID code storage area 71a as a history up to the present time, a configuration in which the progress of a game is controlled using a plurality of base station ID codes may be adopted. That is, the progress of the game is controlled according to the transition of the area where the mobile phone 6 is located up to the present time.

According to the first embodiment, the portable telephone 6
Receives a control signal wirelessly transmitted from a base station that controls a wireless area where the mobile phone 6 is currently located among a plurality of base stations. Then, the received control signal is demodulated to detect the base station ID code, and stored in the ID code storage area 71a. The process of updating the base station ID code is sequentially executed during standby, and the latest base station ID code is 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 value of the base station ID code 80 stored in the ID code storage area 71a, and an image corresponding to the progress of the game is displayed on the display 74.

Therefore, 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 periodically transmitted from the base station to register the position of the mobile phone 6 in the mobile communication system 1 is used. Therefore, the game content can be changed according to the current position information of the user.

Further, as the position information, the base station ID periodically transmitted from the base station in the mobile communication system 1
The configuration using the code also has the following advantages.

That is, as described in JP-A-10-322775, when base station identification information (base station ID code) obtained in response to an incoming call or outgoing call is used,
The base station identification information read from the internal memory during the progress of the game is only the position information acquired at the timing of the incoming call or the outgoing call. 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 obtained when the mobile phone 6 is on standby, the location information of the user can be obtained without performing a call or communication with the mobile phone 6.

[Modification of the First Embodiment] Next, the first

The control different from that of the first embodiment is performed when the radio wave reception state of the control signal is not good. Note that the case where the radio wave reception state of the control signal is not in a good state means, for example, immediately after shifting to a radio area of another base station, or in a space where radio waves are hard to reach such as indoors without windows, mobile communication. For example, if you are in an area outside the jurisdiction of the system.

In this modification, when the radio wave reception state of the control signal is not good, the progress of the game is controlled in accordance with the radio wave reception intensity of the control signal instead of the base station ID code. Therefore, the ID code storage area 75
Only when the radio wave reception state of the control signal is not in a good state, level information 120b of the radio wave reception intensity of the control signal is stored in a in place of the base station ID code 120a. The level information 120b is ranked in order of level 3, level 2, and level 1 in ascending order of radio wave reception intensity.

The game data storage area 75b stores the character control table 81 (FIG. 4) described in the first embodiment.

This character control table 121 is used when determining an enemy character to compete with according to the radio wave reception intensity of the control signal at the time of encounter. The character control table 121 includes, for example,
"Electric wave reception intensity" column 121a, "enemy character" column 12

The “enemy character” column 121b stores one or more types of enemy characters corresponding to each level information stored in the “radio wave reception intensity” column 121a.

When determining an enemy character to compete in the present modification, first, the data stored in the ID code storage area 75a is the base station ID code 120a or the level information 120b of the radio wave reception intensity.
Is determined. In the case of the base station ID code 120a, an enemy character to compete with is determined by the method described in the first embodiment according to the base station ID code 120a and the character control table 81 (see FIG. 4). That is, an enemy character to battle is determined according to the value of the base station ID code 120a.

On the other hand, the case where the data stored in the ID code storage area 75a is the level information 120b of the radio wave reception intensity is as follows. That is, an enemy character to be played is determined from one or more enemy characters stored in the character control table 121 in association with the level information 120b of the radio wave reception intensity stored in the ID code storage area 75a.

FIG. 15 is a diagram showing a data structure of the item control table 122 stored in the game data storage area 75b of the RAM 75. The item control table 122 is used to determine an item to be generated in accordance with a radio signal reception intensity of a control signal when the item is generated. The item control table 122 includes, for example,
"Electric wave reception intensity" column 122a, "item" column 122b

On the other hand, the case where the data stored in the ID code storage area 75a is the level information 120b of the radio wave reception intensity is as follows. That is, the item control table 1 corresponds to the level information 120b of the radio wave reception intensity stored in the ID code storage area 75a.
An item to be generated is determined from one or more items stored in 22.

FIG. 16 is a diagram showing a data structure of the scenario control table 123 stored in the game data storage area 75b of the RAM 75. The scenario control table 123 is used to determine the branch destination scenario according to the radio wave reception intensity of the control signal when branching the progress of the game scenario.

The scenario control table 123 includes, for example,
“Branch point No.” column 123a, “Radio wave reception intensity”
A column 123b and a “branch destination scenario” column 123c are provided.
The “branch point No.” column 123a stores branch point information for branching the progress of the scenario of the game.

In the “branch destination scenario” column 123c, the scenario ID of the branch destination corresponding to each level information stored in the “radio wave reception intensity” column 123b
Information is stored.

The branch control of the progress of the scenario of the game in the present modification is as follows. That is, when any of the branch points is reached in the course of the progress of the game, the reached branch point No. Is determined. Further, it is determined whether the data stored in the ID code storage area 75a is the base station ID code 120a or the level information 120b of the radio wave reception intensity. If it is the base station ID code 120a, the base station ID code 120a and the scenario control table 83
According to (see FIG. 6), the scenario branch of the game is controlled by the method described in the first embodiment. That is, a scenario branch of the game is controlled according to the value of the base station ID code 120a.

When the scenario control table 123 shown in FIG. 16 is compared with the scenario control table 83 (see FIG. 4) described in the first embodiment, the following is found. That is, in the case of the branch point 1, when the radio wave reception state of the control signal is good, it is possible to branch to the scenario a1 or the scenario a2 according to the scenario control table 83 (see FIG. 4) and the base station ID code 120a. is there. On the other hand, when the radio wave reception state of the control signal is not good, the scenario is the scenario a1 or the scenario a2 in the case of the level 1, the scenario a1 only in the case of the level 2, and the special scenario in the case of the level 3. Branching is possible only for scenario a3. As described above, when the radio wave reception state of the control signal is not good, it is possible to reduce the number of branch destination options in the case where the control signal is good and to set a limit, or to provide a new option.

Next, the operation of the mobile phone 6 in this modification will be described. FIG. 17 is a flowchart illustrating an example of an ID code storage process according to the present modification.

Since the process is the same as the ID code storage process described in the embodiment, detailed description is omitted.

The difference between this ID code storing process and the ID code storing process described in the first embodiment is that
This is a case where it is determined in step S105 that the average value of the radio field intensity levels of the m control signals is equal to or less than a predetermined value. In this case, in this modification, the following process is executed.

That is, first, based on the average value of the radio field intensity level of the control signal calculated in step S104,
The level information of the received radio wave intensity with respect to the received m control signals is obtained (step S301). The level information of the radio wave reception intensity is ranked in the order of level 3, level 2, and level 1 in ascending order of the radio wave reception intensity. In each level information, numerical data in which the upper and lower limits of the radio field intensity level are set in advance are set. In step S301, the corresponding level information is specified by comparing the calculated average value of the radio field intensity levels with the numerical data set in each level information.

Next, the obtained radio wave reception intensity level information is stored in the ID code storage area 7 instead of the base station ID code.
5a (step S302). Thereafter, a base station search process is performed (step S106), and a setting for intermittently receiving the control signal from the searched base station is performed (step S107), and the process returns to step S101.

By executing the ID code storing process, when the average value of the radio wave intensity levels of the received m control signals is equal to or more than a predetermined value, that is, when the radio wave reception state of the control signals is good, The base station ID code 120a is stored in the ID code storage area 75a. When the average value of the radio wave intensity levels of the received m control signals is equal to or less than a predetermined value, that is, when the radio wave reception state is not good, radio wave reception for the m control signals is stored in the ID code storage area 75a. The strength level information 120b is stored.

In this game process, the same process steps as those of the game process described in the first embodiment (see FIG. 9) are assigned the same step numbers as in the first embodiment, and duplicate descriptions will be given. Omitted.

First, it is determined whether or not a specific process has occurred during the game progress control period (step S).
501). The specific processing is an encounter processing, an item generation processing, and a scenario branch processing. If 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 any of the processing of the encounter processing, the item generation processing, and the scenario branch processing occurs, first, the type of the generated processing is specified (step S502). Next, the data stored in the ID code storage area 75a is obtained (Step S503). Then, it is determined whether the acquired data is the base station ID code 120a or the radio wave reception intensity level information 120b (step S504).

The obtained data is the base station ID code 120
If it is “a”, steps S205 to S21 of the game process (see FIG. 9) in the first embodiment are performed according to the base station ID code 120a and the type of the generated process.
In the method described in 3, the process of determining the enemy character to be played,
An item generation process and a scenario branch are executed (steps S505 to S513). That is, base station ID code 1
The progress of the game is controlled according to 20a.

On the other hand, if the data acquired in step S504 is the level information 120b of the radio wave reception intensity, the enemy character determining process and the item generating process are performed according to the level information 120b and the type of the generated process. Execute the scenario branch (steps S205 to S205).

Control the progress of the game in accordance with.

More specifically, in the case of the encounter process (step S505), the character control table 12 is associated with the acquired radio wave reception intensity level information 120b.
From the one or more enemy characters stored in No. 1, an enemy character to be played is determined by, for example, a random number (step S506). Then, an image and information relating to the determined enemy character are displayed on the display 74 (step S507).

In the case of item generation processing (step S508), the acquired radio wave reception intensity level information 12
From one or more items stored in the item control table 122 corresponding to 0b, an item to be generated is determined by, for example, a random number (step S509).
Then, the image and information of the determined item are displayed on the display 74 (step S510).

In the case of the scenario branching process (step S511), the processing is as follows. That is, the branch point No. Is determined, and this branch point No. is determined. And the branch scenario information stored in the scenario control table 123 is obtained in association with the obtained radio wave reception intensity level information 120b (step S512). Subsequently, the corresponding branch scenario data is read from the scenario data 86 of the ROM 70 and transferred to the work area 75c of the RAM 75. Then, the subsequent game progress is controlled based on the branch scenario data transferred to the work area 75c (step S513).

According to the present modification, portable telephone 6 receives a control signal wirelessly transmitted from a base station which is in charge of a wireless area where portable telephone 6 is currently located among a plurality of base stations. Then, the level information of the radio wave reception intensity of the received control signal is detected and stored in the ID code storage area 75a.
Then, in the course of the progress of the game, the game proceeds in accordance with the level information of the radio wave reception intensity stored in the ID code storage area 75a, and an image corresponding to the progress of the game is displayed on the display 74. Therefore, the game content such as the scenario branch during the game and the displayed character image and item image can be changed according to the radio wave reception intensity of the control signal. Note that the radio signal for detecting the radio wave reception intensity may be a radio signal transmitted from the base station for outgoing calls, incoming calls, and calls.

In the first embodiment and its modifications, programs and data relating to the game are stored in advance in the R.
The configuration stored in the OM 70 was adopted. However, the configuration may be such that a program or data relating to an arbitrary game can be downloaded to the mobile phone 6 from another device via the base station.

FIG. 19 is a diagram showing an example of the configuration of a system for downloading a program or data relating to a game from another device to a mobile phone via a base station. In this example, programs and data relating to a plurality of games that can be executed by the mobile phone 20 are managed by the center 9 in the mobile phone dedicated network 3. When downloading a program or data relating to a game from the center 9, the mobile phone 20 performs data communication with the center 9 via the corresponding base station 4 e and mobile switching center 8 a.

The portable telephone 20 further includes a flash ROM 22 for storing programs and data relating to the game downloaded from the center 9.
In addition, the ROM 21 stores programs and data for controlling each unit of the mobile phone 20 other than the game function.

Thereafter, when the user operates the key input unit 72 to make an input relating to the selection of the game to be downloaded, the game to be downloaded is determined according to the operation input (step S404). The program and data relating to the determined game are transferred from the center 9 to the base station 4.
e and the mobile switching center 8a to download to the mobile phone 20 (step S405).

Specifically, for example, taking the first embodiment as an example, a program relating to an ID code storage process (see FIG. 8) and a game process (see FIG. 9), a character control table (see FIG. 4) , An item control table (see FIG. 5), a scenario control table (see FIG. 6), scenario data (see FIG. 7), and game data such as images and information on characters and items. At the time of downloading, the programs and data relating to the game received and demodulated are sequentially stored in the flash ROM 22 (step S407).

By this download processing, the portable telephone 20 can download programs and data relating to the game from the center 9 and use them. Therefore, it becomes possible to electronically distribute and sell programs and data relating to the game as software products independently of the device. Note that a configuration may be adopted in which a program or data relating to a game is downloaded from a base station.

It is also possible to download a program or data for updating, rewriting, or adding a part or part of a game program or game data. With this configuration, the game distributor can change the content of the distributed game by preparing programs and data for changing the content of the game in the center 9. For example, by downloading such a program or data to the mobile phone 20, it is possible to change an enemy character to be played or an item to be generated, or to add a new branch scenario or a special event scenario to the game.

A display drive circuit 108, a display 109, an interface circuit 110, and a memory card 111 are provided.

In the mobile communication system 1 for mobile phones shown in FIG. 1, control signals including base station ID codes wirelessly transmitted from base stations 4a to 4f are received by antenna 101. The signal received by the antenna 101 is amplified and frequency converted by the RF unit 102. Then, the demodulation section 103 performs demodulation processing, and extracts necessary reception data. The antenna 101, the RF unit 102, and the demodulation unit 103 correspond to the antenna 61, the RF unit 62, and the demodulation unit 63 of the mobile phone 6 shown in FIG.
When compared with, it has only the following functions. That is, it has a function of receiving control signals wirelessly transmitted from the base stations 4a to 4f and a function of demodulating the received control signals and extracting a base station ID code.

The CPU 104 executes the first program in accordance with the program stored in the ROM 105 and the memory card 111.
The ID code storage process described in the embodiment (FIG. 8)
(See FIG. 9) and game processing (see FIG. 9). ROM1
05 stores an operation system for controlling each unit of the portable game machine 100. The RAM 106 is a memory for temporarily storing programs and data, and has the same memory configuration as the RAM 71 shown in FIG. 3 in the first embodiment.

The key input unit 107 includes direction keys and a plurality of operation buttons. The display driving circuit 108 includes a circuit for driving and controlling the display 109, a display buffer,

The programs and data recorded on the memory card 111 are read as necessary according to instructions from the CPU 104 and transferred to the RAM 106. That is, in the portable game machine 100, the portable game machine 10
A program and data for implementing the present invention are read into the RAM 106 of the portable game device 100 and used by the memory card 111 which is detachably provided to the portable game device 100. Therefore, a program or data for realizing the present invention can be easily distributed and sold as a software product (memory card 111) independently of the device.

The portable game machine 1 having such a configuration
Then, the ID code storing process (see FIG. 8) and the game process (see FIG. 9) 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. 8)
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. However, the ID code storage processing is performed by the base station I in step S202 of the game processing.
Processing that requires D code, ie, encounter processing,
It may be configured to be executed only when any of the item generation processing and the scenario branch processing occurs.

With such a control configuration, the same game control as that of the portable telephone 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 wirelessly transmitted from a base station that controls a wireless area where the portable game device 100 is currently located among a plurality of base stations. Then, the received control signal is demodulated to extract a base station ID code and stored in the RAM 106. The power supply is turned on in the portable game machine 100 in the update processing of the base station ID code.
Or during the period when the game processing is being executed in the portable game machine 100, the game processing is sequentially executed based on a predetermined interrupt request. Then, in the course of the progress of the game, the game is advanced according to the value of the base station ID code stored in the RAM 106, and an image corresponding to the progress of the game is displayed on the display 109.

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.
In addition, in the mobile communication system 1 (see FIG. 1), the position information for making the content of the game different differs from the base stations 4a to 4a.
A base station ID code that is periodically transmitted wirelessly from 4f 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 memory card 111.
And the memory card 111 was used as a recording medium. However, the recording medium is not limited to a memory card, but may be another computer-readable magnetic or optical recording medium or a semiconductor memory.

In the second embodiment, a mobile communication system of a mobile phone is used to obtain position information in the mobile game machine 100. However, a mobile communication system such as a PHS or a pager may be used.
Alternatively, equipment provided independently for the purpose of causing the portable game machine 100 to acquire position information may be used. In this case, the equipment may be prepared by preparing a plurality of transmitting devices for wirelessly transmitting the position identification information or the position identification information in an area under its own jurisdiction, and arranging these transmitting devices as appropriate in consideration of their respective jurisdictions. .

As described above, the present invention has been specifically described based on the first and second embodiments and modifications, but the present invention is not limited to the above embodiments and modifications.
Needless to say, it can be appropriately changed without departing from the gist of the invention.

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

In the first and second embodiments, the content of the game is changed only according to the base station ID code. 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.

In the first and second embodiments, the progress of the game is changed by using the base station ID code as the identification information. However, the identification information is not limited to the base station ID code. That is,
The information may be wireless zone ID information, general call area ID information, or the like.

Also, CDMA (Code Division Multiple)
In a mobile communication system of a mobile phone employing an Access (code division multiple access) system, a control signal wirelessly transmitted from a base station includes base station latitude information and base station longitude information. Therefore, the progress of the game executed on the mobile terminal side may be changed using the base station latitude information and the base station longitude information instead of the base station ID code. That is,
The mobile terminal receives a control signal wirelessly transmitted from a base station that controls a wireless area where the mobile terminal is currently located, among a plurality of base stations. Then, the received control signal is demodulated, and base station latitude information and base station longitude information are detected and stored in an internal memory. Then, in the course of the progress of the game, the game proceeds according to the values of the base station latitude information and the base station longitude information stored in the internal memory, and an image corresponding to the progress of the game is displayed on the display screen. As described above, depending on the base station latitude information and the base station longitude information, the scenario branch in the game and the displayed character image and item image may be different.
