A-2: Operation of First Embodiment Next, the operation of the mobile communication system having the above-described configuration will be described by focusing on the “railway domination game” service.
It is assumed that map data corresponding to the “railway domination game” is prepared in the map database MDB in advance.

First, when a subscriber of the mobile packet communication network MPN starts using the "railway domination game" according to a predetermined procedure, the service providing apparatus GRIMM reads the subscriber registration information file (see FIG. 3) of the subscriber database UDB. A history file (FIG. 6) is associated with the record of the subscriber.
Is created in the subscriber database UDB, and a plot area table is created in the map database MDB. At this time, for all records in the plot area table, the value of the flag is a value indicating “not transmitted”.

Then, when the subscriber operates the input section MS4 of the mobile station MS and makes a call in the target area of the "railroad domination game", the base station ID of the fixed base station BSf connected at this time becomes: The information is supplied to the mobile communication service control device M-SCP in association with the time information and the telephone number of the mobile device MS, and the location is registered. When the location registration is performed, the mobile communication service control device M-SCP sends the base station ID together with the telephone number of the corresponding mobile device MS via the mobile packet gateway relay processing device M-PGW to the service providing device G-SCP.
Supply to RIMM. The service providing apparatus GRIMM refers to a base station arrangement table (not shown) and stores the base station ID.
Is converted to latitude / longitude information, and it is checked whether or not the same information as the latitude / longitude information exists in the history file corresponding to the mobile station MS. In this case, the latitude / longitude information is added to the history file.

Further, the subscriber is an input unit M of the mobile station MS.
By performing a predetermined operation on S4, a menu shown in FIG. 7 is displayed on display portion MS3. Here, when the subscriber operates the input unit MS4 and selects the option of “3. Specifically, the mobile station MS makes a call in the packet communication mode, and the fixed base station BSf, the packet subscriber processing unit PPM, and the mobile packet gateway relay processing unit MP
A domination status display request is transmitted to the service providing device GRIMM via the GW. Upon receiving the domination information display request,
The service providing device GRIMM refers to the history file in the subscriber database UDB and the plot area table in the map data in the map database MDB corresponding to the telephone number in the domination status display request, and obtains the latitude / longitude information in the history file. And the position 1 and the position 2 in the record where the flag of the plot area table is not “transmitted”,
A plot area in which the position represented by the latitude / longitude information exists in the area defined by the pair of position 1 and position 2 is specified. Then, the service providing device GRIMM sets the value of the flag corresponding to the specified plot area to “transmitted”.
And clear the contents of the history file. Thereby, the enlargement of the history file can be suppressed.

Then, the service providing device GRIMM
Based on the coordinates 1 and 2 of the plot area in which the value of the flag indicates “transmitted”, image data representing an image in which the pixel values in the plot area are inverted on the map is generated,
The data is returned to the mobile station MS as HTML format data.
In the mobile device MS, the data in the HTML format is interpreted by the microcomputer MS5, and for example, an image shown in FIG. 8 is displayed on the display unit MS3.

When the values of the flags for all the plot areas in the plot area table become values indicating “transmitted”, the service providing apparatus GRIMM sends a message in the generated image to the effect that the along-line domination game has ended. insert. When this image is displayed on the display unit MS3 of the mobile device MS, the subscriber can easily know that the railroad domination game has been completed. In the present embodiment, the history file for the subscriber who has completed the railroad domination game is deleted by the service providing device GRIMM.

A-3: Supplement As described above, according to the present embodiment, information that has not been used until now (past position information) without significantly changing the configuration of the existing mobile communication network. Can be provided. Further, since the position of the mobile device MS is specified in the mobile communication network MN, fairness can be guaranteed for the subscriber.

In the above-described embodiment, since the purpose is to provide a game service, information based on the contents of the history file is transmitted to the mobile station MS. The present invention is not limited to this, and can be used for various applications. If time information, transmission time, and the like are also added to the history file, the history file can be used by more advanced applications.

Although the duplication of information in the history file is avoided, the duplication may be allowed. Further, when the game service to be provided has a time limit, only information obtained within a predetermined time may be added to the history file, or time information may be added to the history file, and the plotting process may be performed. Information outside the predetermined time may be ignored. Also, information indicating the continuous communication time may be stored in the history file. Furthermore, the conditions for terminating the game in which the game is completed when all plot areas are conquered are exemplified, but the present invention is not limited to this.

Since it is assumed that the display section MS3 has a black and white binary display section, a display method of inverting the pixel values in the plot area is adopted. Various displays can be performed. For example, it is also possible to display in different colors according to frequency, time, and the like. Also, needless to say,
The plot area is not limited to a rectangle.

Further, although the area where the mobile device MS moves is assumed to be a two-dimensional plane, the position of the mobile device MS may be three-dimensionally captured, such as on the ground and underground. However, in a communication system in which the GPS is used in the location registration processing of the mobile station MS, the movable area of the mobile station MS must be a two-dimensional plane. Needless to say, a plurality of plot areas are not allowed to occupy the same space.

Although the accuracy of specifying the position of the mobile station MS depends on the communication system, the accuracy should be reduced in an environment where confidentiality is not sufficiently ensured. Although the information indicating the position of the mobile device MS is automatically added to the history file, the user of the mobile device MS may manually select whether or not to add the information to the history file.

Here, a modified example of an application to a game other than the roadside domination game will be described. However, since the basic configuration and operation are the same as those in the alongside line domination game, the description thereof is omitted.

A-4: Modifications (1) National Conquest Game FIG. 9 is a diagram illustrating a basic map of the national conquest game. As is clear from this figure, in this game, the Japanese archipelago is divided into nine rectangular plot areas, and when the mobile station MS transmits in an area corresponding to each plot area, the pixels in the corresponding plot area are inverted, The game is completed when all areas are conquered.

(2) Airport Conquest Game FIG. 10 is a diagram illustrating a basic map of the airport conquest game. In this figure, a white rectangle is a plot area, and the others are background images. Each plot area is provided corresponding to the area around the airport. That is, when the mobile station MS makes a call in an area (around the airport) corresponding to each plot area, the pixels in the corresponding plot area are inverted, and when all areas are conquered, the game is completed.

(3) World Domination Game FIG. 11 is a diagram illustrating a basic map of the world domination game. In this figure, a white rectangle is a plot area, and the others are background images. Each plot area is provided corresponding to an area of a major city in the world. That is, in the area (around a major city) corresponding to each plot area, the mobile device M
When S transmits, the pixels in the corresponding plot area are inverted,
The game is completed when all areas are conquered.

B: Second Embodiment Next, a second embodiment of the present invention will be described. The second embodiment of the present invention is a mobile communication system that provides a “satellite domination game” service. Note that the satellite domination game in the present embodiment refers to a mobile communication network using a satellite having a base station function, in which a mobile station transmits a signal via the satellite to conquer the satellite, and is used. This is a game that ends when you conquer all possible satellites. In the present embodiment, it is assumed that the satellite located in the sky differs depending on the time.

B-1: Configuration of Second Embodiment FIG. 12 is a block diagram showing a configuration of a communication system according to a second embodiment of the present invention. In this figure, the parts common to FIG. 1 are denoted by the same reference numerals, and the description of the parts common to the first embodiment is omitted. The configuration shown in FIG. 12 differs from that shown in FIG. 1 in that a mobile base station BSm is provided instead of the fixed base station BSf, and that the packet subscriber processing device P
The point is that a packet subscriber processing unit PPMr and a digital mobile communication switch MLSr are provided in place of the PM and the digital mobile communication switch MLS.

The fixed base station BSf is set to 1 for one satellite.
Only one base station is provided, for example, only 66 base stations are provided in total. In the present embodiment, when focusing on a certain area, it is assumed that all the 66 satellites pass through the sky. Thus, the mobile station MS
m is not fixed, the service providing device G
The conversion from the base station ID to the latitude / longitude information in the RIMM is not performed, and the base station ID itself is used instead of the latitude / longitude information in the first embodiment. Therefore, the base station ID is used in the history file shown in FIG. 6 instead of the latitude / longitude information (see FIG. 13), and the base station ID is used instead of the position 1 and the position 2 in the plot area table shown in FIG. (See FIG. 14). It is assumed that the map data in the map database MDB includes image data representing the map shown in FIG. The packet subscriber processing unit PPMr and the digital mobile communication switching system MLSr have the same functions as the packet subscriber processing unit PPM and the digital mobile communication switching system MLS except that they are wirelessly connected to the mobile base station BSm.

B-2: Operation of the Second Embodiment Next, the operation of the mobile communication system having the above-described configuration will be described focusing on the “satellite domination game” service.

First, when a subscriber of the mobile packet communication network MPN starts using the “satellite domination game” according to a predetermined procedure, the service providing apparatus GRIMM sets the subscriber registration information file in the subscriber database UDB (see FIG. 3). A history file (see FIG. 13) is created in the subscriber database UDB in association with the record of the subscriber, and a plot area table (see FIG. 14) is created in the map database MDB. At this time, for all records in the plot area table, the value of the flag is a value indicating “not transmitted”.

When the subscriber operates the input section MS4 of the mobile station MS to make a call, the base station ID of the mobile base station BSm connected at this time indicates the time information and the mobile station MS.
Is supplied from the packet subscriber processing unit PPMr or the digital mobile communication exchange MLSr to the mobile communication service control unit M-SCP in correspondence with the telephone number of the mobile telephone, and the location is registered. When the location registration is performed, the mobile communication service control device M-SCP supplies the base station ID together with the telephone number of the corresponding mobile device MS to the service providing device GRIMM via the mobile packet gateway relay processing device M-PGW. The service providing device GRIMM is the base station I
It checks whether or not the same information as that of D exists in the history file corresponding to the mobile station MS. If so, nothing is performed. If not, the base station ID is added to the history file. I do.

Further, the subscriber is an input unit M of the mobile station MS.
By performing a predetermined operation on S4, a predetermined menu is displayed on the display unit MS3. Here, when the subscriber operates the input unit MS4 and selects an option for displaying the domination status of the satellite, a process for displaying the domination status is performed. Specifically, the mobile station MS transmits in the packet communication mode, and the mobile base station BSm, the packet subscriber processing unit PPMr, and the mobile packet gateway relay processing unit M-PG
A domination status display request is transmitted to the service providing device GRIMM via W. Upon receiving the domination information display request, the service providing device GRIMM refers to the history file in the subscriber database UDB and the plot area table in the map data in the map database MDB corresponding to the telephone number in the domination status display request, The base station ID in the history file is compared with the base station ID in the record in which the flag of the plot area table is not “transmitted”, and a plot area in which both match is specified. Then, the service providing device GRIMM changes the value of the flag corresponding to the specified plot area to a value indicating “transmitted” and clears the contents of the history file.

Then, the service providing device GRIMM
Based on the coordinates 1 and 2 of the plot area in which the value of the flag indicates “transmitted”, image data representing an image in which the pixel values in the plot area are inverted on the map is generated,
The data is returned to the mobile station MS as HTML format data.
In the mobile device MS, the data in the HTML format is interpreted by the microcomputer MS5, and an image represented by the image data generated by the service providing device GRIMM is displayed on the display unit MS3.

When the value of the flag relating to all (for example, 66) plot areas in the plot area table becomes a value indicating “transmitted”, the service providing apparatus GRIMM ends the satellite domination game in the generated image. Insert a message to the effect that This image is the display M of the mobile device MS.
When displayed by S3, the subscriber can easily know that the satellite domination game has been completed. In this embodiment, the history file for the subscriber who has completed the satellite domination game is deleted by the service providing device GRIMM.

B-3: Supplement The items described in the supplement regarding the first embodiment are basically the same as those of the second embodiment. However, the second embodiment is different in that the base station ID of the mobile base station BSm connected to the mobile station MS is used instead of the information indicating the position of the mobile station MS. In the second embodiment,
Since a general subscriber does not know the operation rules of the mobile base station BSm, the process is completed when a predetermined number of plot areas in which the pixel values are inverted on the display surface of the display unit MS3 are arranged vertically, horizontally, or diagonally. Alternatively, a condition such as a bingo game may be set as a completion condition. In addition, although an example has been described in which the satellites are merely base stations, each satellite may be configured to have a switching function. That is, if the mobile communication service control device M-SCP is configured to be able to perform the location registration processing of the mobile device MS, the configuration of the wireless system is arbitrary.

[0052]

As described above, according to the present invention,
Since the identification information (information unique to the mobile communication network) of the base station connected to the mobile device in the past is accumulated, it is possible to realize an application using the information. For example, by performing display according to the stored identification information in the mobile device, the subscriber can confirm the transition of the base station.
