Abstract

PROBLEM TO BE SOLVED: To implement a large-scale network game system by not requiring the existence of a server with a traffic concentration. SOLUTION: User terminals 501 -506 of users tell request of participation in a game to a terminal 20 of a service provider providing a network game in which the users are going to participate. Each user terminal uses a piece of information received from the service terminal 20 to set a condition so as to receive only a piece of information required for a process of one's game among pieces of information about the game transmitted from the user terminal of other users participating in the game in a semantic information network 10 as a filter. Each user terminal, when one's state in the game changes, transmits the changed state to the semantic information network 10 as an event. When each user terminal receives an event showing a change of a state from the user terminal of the other user, it changes a state in the game of the other user.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network game realization method and a network game system for playing a game with another user in a remote place via a network.

[0002]

2. Description of the Related Art In recent years, due to the improvement of the internet connection rate of personal computers, the broadbandization of networks, the constant connection, the provision of communication functions for home-use game machines, etc. Network games, which play games over the network, are attracting attention.

For example, "Network game system" disclosed in Japanese Patent Laid-Open No. 11-319319 discloses a network game system in which a plurality of terminals can play a computer game on a network in which a plurality of terminals are connected to a server. There is. In this network game system, each of the plurality of terminals supplies the server with the situation data of the computer game being executed,
The server is characterized in that integrated data is generated for the entire plurality of terminals based on the situation data and the integrated data is supplied to each of the plurality of terminals.

Further, "Network game system" described in JP-A-11-288393 discloses a network game system composed of a plurality of game servers. In this network game system, a plurality of types of game software are stored on each game server, and each game is played and the number of game terminals that can participate at the same time according to the communication distance between the game terminal and the game server. Each game terminal selects and executes one of different types of game software having different contents, and thereby increases the total number of game terminals that can simultaneously participate in the network game system.

Further, in the "real time network system" described in Japanese Patent Laid-Open No. 9-6700, a server and a terminal device storing game software capable of transmitting and receiving data to and from the server are connected by a communication line. ,
The data to be transmitted / received is the data of the management number attached to each of the blocks of the data array to be transmitted in a predetermined length, and the corresponding data array of the management number data is blocked. Is read and the original data array is reproduced. In this network system, at least data necessary for other users out of the data obtained by the user operating the game software is transmitted to the server, and this data is read out by the other users, and based on the data, the users Were to play games at the same time.

Further, in the "communication game device and communication game management device" described in Japanese Patent Laid-Open No. 6-327835, an area (background, etc.) having a relatively large amount of information in the game screen and a relatively small change. Data corresponding to a region (such as a distant view) is read from package media (such as a CD-ROM or memory cartridge) and processed as the first image data, and a region with a relatively small amount of information (appearing characters, etc.) on the game screen. ) Image data as a second image data from a communication line, and a synthesizing means for synthesizing the first image data and the second image data to generate display data of a game screen. An apparatus and a communication game management apparatus are disclosed. According to this communication game device, the precision of the expression can be obtained, the appearing character that the user likes can be used, and the network game with high real-time property can be realized.

However, in the various conventional techniques described above, a game server is provided to realize a network game, and in order to reduce the server load and communication traffic, the servers are distributed and only necessary data is communicated. However, these methods cannot avoid the burden on the server and the network around the server when a large number of users participate. Also, regarding the information to be transmitted, all necessary data is transmitted and collected, so even if the unit of the information is small, the burden on the server and the network around the server will be small when the number of information is huge. Inevitable. Therefore, in the network game system according to the conventional technique described above, the number of users that can be used is limited, and it is difficult to realize a large-scale and large-scale use environment.

[0008]

In the above-mentioned conventional network game system, a server is required for transmitting and receiving information between users, so that when a large number of users are used, traffic concentration occurs. However, there is a problem that the number of people who can use it is limited.

An object of the present invention is to provide a network game system in which the number of users that can be used is unlimited by eliminating the need for a server where traffic is concentrated.

[0010]

In order to achieve the above object, the network game system of the present invention comprises: a transmitting terminal for transmitting data as an event; and a selective receiving of the data transmitted as an event. , A game for playing a game with another user in a remote place via a network by using a semantic information network composed of a receiving terminal to which a filter including an event type and an acquisition condition is set. A method for realizing a network game using a semantic information network, wherein a user terminal of a user who wants to participate in the game participates in the network game at a terminal of a service provider who is providing the network game to participate. The step of notifying that the user wants to Upon receipt of the notification to participate,
Transmitting each of the information necessary for participating in the game to the user terminal, and using the information received by each of the user terminals from the service terminal from the user terminals of other users participating in the game. Setting a condition for receiving only the information necessary for the progress of the game of itself from the transmitted information on the game as a filter in the semantic information network; When the state of the above changes, the step of transmitting the changed state to the semantic information network as an event, and when each of the user terminals receives an event indicating the state change from the user terminals of other users, Changing the state of another user during the game.

According to the present invention, the game can be progressed by directly transmitting and receiving the event and the information between the user terminals participating in the game using the semantic information network. Therefore, it is not necessary to have a server in which traffic is concentrated, and it is possible to realize a large-scale network game system that can be simultaneously used by a large number of people.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Since the present invention is premised on the use of a semantic information network system which is a distributed network system in which the message nature of information to be transmitted is enhanced, this semantic information network will first be described below. Regarding this semantic information network, Japanese Patent Application No. 2000-062447 and Japanese Patent Application No. 2000-2840 are available.
76 or Takanari Hoshiai et al., "Semantic Information Network Architecture", IEICE Transactions B, Vol.J8
4-B, No. 3, pp. 411-424 (2001-3). Therefore, only the outline of this semantic information network will be described below.

First, the semantic information network (Semantic I
nformation-Oriented Network (hereinafter referred to as SION) network architecture.
FIG. 1 shows a network model of SION. here,
For convenience of explanation, the terminal 2 is referred to as the transmission terminal 2 of the event sender.
1 and the reception terminal 22 of the event receiver are separately described. The event receiver uses the receiving terminal 22 as the meta information of the semantic information (type of event to be received and acquisition condition) of the event that he / she wants to receive as SION.
Register to 1. This is called a filter. On the other hand, the event sender uses the sending terminal 21 to perform SION
By sending an event to 1, SON is given an incentive. As shown in FIG. 2, this event is composed of semantic information describing the characteristics of the event and data. The definition of the semantic information is shown in FIG. The semantic information is meta information of the event and is an instance of the semantic information type (event type).

The SION 1 is an autonomous decentralized matching network for matching (filtering) the events sent by the event sender against the filter registered by the event receiver. As a result of the matching, the filter that the event passed (reacted to the event) is fired (Ignitio
n) and the receiving terminal 22 of the corresponding event receiver is autonomously activated. With this mechanism, the target terminal 2 can be searched and discovered in a scalable and real-time manner from an unspecified number of terminals 2.

Next, the event type will be described.
FIG. 4 shows a definition example of an event type which is a template of an event. As shown in FIG. 4, the event type includes an event type name (Event type name), a condition name (in FIG. 4, “Service” and “CPU power” correspond), and a data type for each condition name ( St
ring and Long correspond) and conditional expressions (== and> = correspond) are defined. The event type name is a name for uniquely identifying the event type.

The parent type of the event type can be inherited.

As shown in FIG. 5, an event is created according to the data structure of the event type. An event is an event type name, a combination of condition name and condition value, and
It is composed of the data part. An error will occur if the condition name, condition expression, or condition value defined in the event does not match the event type. However, the condition name used in the event may be a subset of the event type.

FIG. 6 shows an example of filter definition. The filter uses the event type name (Event type nam
e), attribute name (in Fig. 6, "CPU power" and "Ag"
It consists of a pair of "e") and an attribute value (corresponding to 200 or 25 in FIG. 6). Only the events belonging to the event type defined by the accepted event type name are to be filtered. Can have multiple event type names defined, and
It is also possible to target all events by specifying a wild card (*. *). If the attribute name defined by the filter does not exist in the event type condition name defined by the accepted event type name, an error occurs. However, it may be a subset of event types.

Next, the configuration of SION1 will be described. Figure 7
FIG. 3 is a diagram showing a configuration of SION1. As shown in FIG. 7, SION1 is a semantic information switch (Semantic Informa).
tion-Switch, shown as SI-SW in the drawing), Semantic Information-Router (shown as SI-R in the drawing), Semantic information gateway (Semant)
ic Information-Gateway, which is shown as SI-GW in the drawing).

The semantic information switch (SI-SW) is a switching mechanism for collating the semantic information registered as a filter with the semantic information given to the event and, as a result, activating the terminal 2 of the event receiver who has fired. provide. The semantic information switch (SI-SW) and each terminal 2 are connected in a star type.

The semantic information router (SI-R) performs event path selection between the semantic information switches and also the terminal 2
It is responsible for transferring the event sent from the to the semantic information switch to another semantic information switch. This is achieved by dynamic event routing based on semantic information.

The semantic information gateway (SI-GW) is
Transfers events between event places. Here, the event place is a minimum unit (ontology domain) that guarantees a common semantic information space. In the event place, the uniqueness of the ontology system such as the name, concept, vocabulary, meaning, and association of the event type is guaranteed, and the semantic information is described based on the common ontology. Basically, the event sent from the terminal 2 of the event sender circulates only in the event place, but the semantic information gateway (SI-
GW) enables mutual distribution of events between event places having different ontology systems. At this time, the semantic information gateway (SI-G
W) performs the ontology conversion of the event and then transfers the event to a different event place.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

(First Embodiment) First, FIG. 8 shows a configuration of a network game system according to a first embodiment of the present invention. The network game system of the present embodiment is a game in which a large number of users behave arbitrarily in a common field, such as performing an event instead of a character in a virtual world in which virtual monsters such as dragons and goblins live. The game RP
Introduced as software that provides G (Role Playing Game) and community.

The network game system of the present embodiment, as shown in FIG.
And service terminals 20 and user terminals 50 ₁ to 50 ₆ connected to the semantic information network 10. Then, service terminal 20, the user terminals 50 ₁ -
50 ₆ is provided with a network game control unit 30.

In the present embodiment, the service terminal 20 and the network game control section 30 provided in each of the user terminals 50 ₁ to 50 ₆ use a medium such as a CD or a means such as a download and the like. It is assumed that the data is distributed to the service terminal, and at the same time, the data and the game field commonly held in the game are also distributed. The semantic information network 10 used here
Then, from a large number of unspecified people, the transmission destinations are narrowed down according to the conditions, and the notification is given to the destinations that meet the specific conditions. In order to use this, a registration mechanism for conditions etc. is required.

Hereinafter, when simply referred to as “event”, it means “event” and is distinguished from the one described as “event in the semantic information network”.

Further, the network game control unit 30 is
As shown in FIG. 9, the game participation means 31, the information deletion means 32, the event registration means 33, the event state change means 34, the information registration means 35, and the information collection means 36.
An event information transmitting unit 37, an event deletion notifying unit 38, an information receiving unit 39, and an information change transmitting unit 40.
, Conditional messaging transmission means 41, meaning information registration means 42, display means 43, user information transmission means 44, message reception means 45, message reply means 46, state storage means 47, meaning information network. And a detaching means 48.

The game participation registration means 31 performs processing for the user to participate in the game. Specifically, the game participation registration means 31 is the service terminal 20 of the service provider who is providing the network game to participate.
Notify that you want to participate in the network game.

The information registration means 35 uses the information received from the service terminal 20 to determine the progress of its own game from the information about the game transmitted from the user terminals of other users participating in the game. A condition for receiving only necessary information is set as a filter in the semantic information network 10. The information necessary for the progress of one's game is, for example, information indicating a certain range centered on the current position of the user in the world called a field which is a virtual space in the game.

The information change transmitting means 40 transmits the changed state to the semantic information network 10 as an event in the semantic information network when its own state changes during the game. The information collecting unit 36 and the display unit 43 perform a process of displaying the information notified from the user terminals of other users by reflecting the information in the field of the own terminal.

The event registration means 33 is the service terminal 2
From 0, register the event condition that occurs in the field. The event state changing means 34 receives an action for an event condition occurring in the field and changes the state of the event.

The event deletion notifying means 38 notifies that the item is deleted when the item is no longer needed due to achievement of the item such as a task in the game. Information deletion means 3
Reference numeral 2 indicates the meaning information condition corresponding to the deletion notice notified by the event deletion notifying means 38.
The process of deleting from 0 is performed.

The state storage means 47 stores the current state of the user during the game when the game is interrupted. The meaning information network leaving means 48 leaves the meaning information network 10 so that the user terminal in the non-communication state is not notified during the state. When resuming the game, the semantic information re-registration unit 42 reads the last information stored in the state storage unit 47 when the game was interrupted, and re-registers the game using the information.

The conditional messaging transmission means 41 is
Among the many users participating in the game, a condition for a user who should send a message is set, and an event in the semantic information network based on the condition is transmitted to the semantic information network 10. Message receiving means 45
Receives only the message from the conditional messaging transmitting means 41 in the other user terminal that matches the set filter condition. The message replying unit 46 replies to the message received by the message receiving unit 45.

Next, the operation of the network game system of this embodiment will be described in detail with reference to the drawings.
In the following description, the case where the user of the user terminal 50 ₆ participates in a network game provided by the service provider of the service terminal 20 and plays a game will be described. (Participation Phase) FIG. 10 shows a participation phase for performing a procedure for participating in the game. When the user of the user terminal 50 ₆ wants to participate in the network game, the game participation means 31 of the network game control unit 30 is used to perform the game participation procedure. At this time, the user terminal 50 ₆ performs a participation procedure by installing and executing an application for realizing the network game control unit 30. When actually holding the game, the network game provider may collect the participation fee in this participation phase.

Specifically, the game participation means 31 accesses the HP or the like provided by the service terminal 20 and explicitly applies the mail address or the like of its own user terminal to apply for an account. Then, the service terminal 20 sends the e-mail address with login information, and the user terminal receives the login information and uses the login information to log in to the service terminal 20 to download and obtain basic software, application programs, field information, and the like. . (Registration Phase) Next, FIG. 11 shows a registration phase in which initial settings for starting the game are performed. The user terminal 50 ₆ uses the information registration means 35 in the network control unit 30 to register the user information, which is changed according to the game situation, in the common information field existing locally in the semantic information network 10. The service terminal 20 also performs the process of registering the provided event information in the semantic information network 10 by the event registration means 33 in the network game control unit 30, as in the case of the user terminal 50 ₆ .

For example, if a current user is at the position (30, 30) in the field coordinates, the information registration means 35 in the user terminal of the user sets the received position information as (x, y), Field of view is 1 in field coordinates
When the number of cells is 0, the filter condition of 30-10 <x <= 30 + 10 30-10 <y <= 30 + 10 is registered in the semantic information network 10. (Game Execution Phase) Next, FIG. 12 shows a game execution phase performed when the game is actually executed. The game execution phase is an opponent that needs to communicate with the user when he / she moves in the field or changes information (status) (for example, an opponent who is near in the field). It is a phase for notifying to. Here, just like saying that people on the other side of the globe are not hindering their current lives without knowing what they are currently doing, they will be able to understand what distant users are doing in the field. There is no need to know, and there is no need to notify the user of the status change.

For example, when a certain user moves to (20, 25), the filter registered in the registration phase matches the condition, and the information of the moving user is added to the field of the user who installed the filter.
If another user moves to (50, 45), the user who has set the event condition in the semantic information network in the registration phase is not notified and the field information of the user is not changed.

The information changing means 40 of the user terminal 50 ₆ is
When the position information of the user in the field of the game is transmitted as an event in the semantic information network, the event in the semantic information network causes the information receiving means 3 of the service terminal 20 and the user terminal 50 _2.
9 received. Then, the service terminal 20 transmits the event information by the event information transmitting means 37, and the user terminal 50 ₂ returns the user information by the user information transmitting means 44. These pieces of information are received by the information collecting means 36 of the user terminal 50 ₆ and stored in the storage device 4.

By performing such processing, the user of the user terminal 50 ₆ can freely move within the field during the game and obtain information of other users existing within a certain range of the position within the field. can do. (Game End Phase) Next, FIG. 13 shows a game end phase for ending the game. When a user clears a game task, it is necessary to set the end of the task. Further, at this time, a part of the entry fee is backed to the cleared user in the form of a prize, so that the user's willingness to participate can be improved.

The game ending procedure is specifically performed as follows.

First, the event status changing means 34 of the service terminal 20 sends a status change notification to the meaning information network 1
When it is transmitted to 0, the information collecting means 36 of the user terminal 50 ₆
Receives this status change notification. Then, when the event deletion notifying means 38 of the service terminal 20 transmits the deletion notification to the semantic information network 10, the deletion notification is received by the information collecting means 36 of the user terminal 50 ₆ . Then, the information deleting means 3 of the service terminal 20 is further added.
When 2 deletes the meaning information condition corresponding to the deletion notification from the meaning information network 10 and notifies the meaning information network 10 that the deletion is completed, this notification is received by the information collecting means 36 of the user terminal 50 _6. It (Messaging Phase) Next, FIG. 14 shows a phase of messaging between user terminals while the game is in progress. In this messaging phase, messaging is selectively performed to the user terminals of other users participating in the same game. The condition is set arbitrarily, and for example, selective messaging is performed under conditions such as a user terminal of a user who exists in an arbitrary area and a user terminal of a user whose specific status value is a condition value or more.

For example, from the point of view of myself, 5 in field coordinates
If you think that you want to invite a thief to a user who is within 0 squares and has a technique to unlock the key (in addition, the condition that the magic can be used or the physical strength is above a certain value) By matching the position condition of and the personal status, the message can be sent to a specific partner.

In this messaging phase, specifically, the following processing is performed.

First, the conditional messaging transmission means 41 of the user terminal 50 ₆ transmits to the semantic information network 10 an event in the semantic information network in which the conditions of the user who should send the message are set. Then, the message receiving means 45 of the user terminals 50 ₂ and 50 ₄ that meet the set conditions receives the event in the semantic information network. Then, a message corresponding to the message received by the message replying means 46 of the user terminals 50 ₂ and 50 ₄ is sent to the message replying means 4
When the message is returned to the semantic information network 10 using 6, this message is received by the message receiving means 45.

In this way, messages can be exchanged with a user who meets a certain condition among other users who participate in the same game. (Game Interruption Phase) FIG. 15 shows an interruption phase in which the game is temporarily interrupted and a procedure for resuming the game later is performed.
Here, a case where the user of the user terminal 50 ₆ interrupts the game will be described. The user who wants to interrupt the game notifies the information change transmission means 40 of the state change. Then, the notification from the user terminal 50 ₆ is received by the information receiving means 39 of the service terminal 20 and the user terminal 50 ₂ , and the information regarding the user of the user terminal 50 ₆ is deleted at each terminal. Then, the user terminal 50
_{In step 6} , the state saving means 47 saves the current state of the game in the storage device 4.

Further, since it is considered that communication is disconnected at the user terminal, at the user terminal 50 ₆ , the semantic information network disconnecting means 48 simultaneously disconnects from the semantic information network 10. By performing such processing, the game can be interrupted without affecting other users or the entire network game system. (Resume Phase of Interrupted Game) FIG. 16 shows a restart phase for resuming the interrupted game. In the user terminal 50 ₆ of the user to resume the game, meaning information re-registration means 42 attract data at the time of suspension from the storage device 4, and re-register with the semantic information network 10, change information changing transmission means 40 information Send a notification. Then, this change notification is received by the information receiving means 39 of the service terminal 20 and the user terminal 50 ₂ . This user terminal 50 ₆
In the service terminal 20 that has received the change notification from, the event information is transmitted by the event information transmitting means 37. Further, in the user terminal 50 _{2 which} has received the change notification from the user terminal 50 ₆ , the user information transmitting means 44 transmits the user information. These pieces of information are received by the information collecting means 36 of the user terminal 50 ₆ .

By performing such processing, the game can be restarted without affecting other users or the game system. For example, if the restarted position is sent as an event condition, if the filter condition registered in the registration phase is met, the information of the restarted user is passed to the user who installed the filter, and the restart of the game in progress is realized. it can.

According to the network game system of the present embodiment, the series of processes described above are not performed by setting up a server and registering there to play a game. By exchanging information, you can participate in the game by installing the required software without installing a server. Further, since a server for managing the whole is unnecessary, a large-scale network game in which a large number of people participate can be realized.

Further, according to the network game system of this embodiment, the user can interrupt the network game at any timing without affecting other users and the entire game system. It is possible to return to the network game at the desired timing without affecting other users or the game system.

(Second Embodiment) Next, a second embodiment of the network game system of the present invention will be described.

The first embodiment described above is an RPG.
The present invention is applied to the network game system of the present embodiment, but the present invention is applied to a camp game. According to this embodiment, although some functions are limited, a network game can be executed without providing a server. The basic configuration of the network game system of the present embodiment is almost the same as the configuration of the network game system of the first embodiment shown in FIG. 8, and the filter conditions set in the semantic information network 10 and the semantic information to be transmitted. Only the contents of the event in the network are different. (Participation / Registration Phase) Different from the case of the first embodiment, the information held by each user terminal is data within the territory managed by the user terminal. Then, in the case of the present embodiment, the position information of one's own territory is registered in the filter as a filter condition set in the semantic information network 10. (Game execution phase) When performing an action (attack, alliance, tribute, reconnaissance, etc.) on a user terminal that operates another position, it can be performed by knowing the information of the user terminal that is the opponent. . For example, when a certain user attacks a certain area, the condition indicating the attacked area is transmitted to the semantic information network 10 as an event in the semantic information network. In this case, the user who matches the transmitted event in the semantic information network with the filter condition is the owner of the area, and thus the battle is started between them in this game.

Although not shown in the figure, the service terminal and the user terminal in the network game system of this embodiment are provided with a recording medium recording a program for executing the above-described network game realizing method. ing. This recording medium may be a magnetic disk, a semiconductor memory or another recording medium. This program is read from the recording medium to the service terminal and the user terminal and controls the operation of the service terminal and the user terminal. Specifically, the CPU in the service terminal and user terminal
The above process is realized by instructing the hardware resources of the service terminal and the user terminal to perform a specific process under the control of this program.

[0055]

As described above, according to the present invention,
Since it is possible to directly transmit and receive the event information and the information of each user between the user terminals participating in the game using the semantic information network, the game can proceed, so that the existence of a server where traffic is concentrated becomes unnecessary, It is possible to obtain an effect that it is possible to realize a large-scale network game system that can be simultaneously used by a large number of people.
