<Configuration of chat system>
FIG. 1 is a schematic diagram showing an outline of a chat system according to the present embodiment. The chat system SYM includes a plurality of client devices 1A and 1B and a server device 2. The server device 2 includes a plurality of matching servers 3A, 3B, 3C and a message server 4. Each client device 1, each matching server 3, and message server 4 are connected to the Internet 30 and perform data communication via the Internet 30. In the following description, the users of the client devices 1A and 1B are referred to as users A and B, respectively. When it is not necessary to distinguish between the client devices 1A and 1B, they are simply referred to as the client device 1, and when it is necessary to distinguish between the client devices and their constituent elements, each is followed by a symbol. A and B are appended. Similarly, when it is not necessary to separately describe the matching servers 3A, 3B, and 3C, the matching server 3 is simply described as the matching server 3 and each matching server and each component thereof must be described separately. In each case, A, B, and C are appended to the end of each symbol. The numbers of client terminals 1 and matching servers 3 are examples, and are not limited to the above. The matching server 3 and the message server 4 do not need to be included in one server device 2 and may be provided individually.

  The client device 1 generates participation request information that can identify one chat room in response to a participation request from the user to the chat system SYS. Further, exit request information capable of specifying the chat room is generated in response to the exit request from the user. The client terminal device 1 transmits participation request information in response to the generation of participation request information, and transmits the exit request information in response to generation of the exit request information.

  The participation request from the user to the chat system SYS includes a request to open a chat room and a request to enter the chat room. In this case, the client device 1 generates setting request information as participation request information corresponding to the opening request, and generates room entry request information as participation request information corresponding to the room entry request.

  The matching server 3 receives participation request information and leaving request information, respectively. In the storage unit 17 (shown in FIG. 4) of the matching server 3, the client device 1 and the chat room can be registered in association with each other.

  When one chat room specified by the received participation request information is registered in the storage unit 17, the matching server 3 registers the client device 1 in the storage unit 17 in association with the chat room. When one chat room specified by the received participation request information is not registered in the storage unit 17, the client device 1 and the chat room are associated with each other and registered in the storage unit 17.

When the matching server 3 receives the setting request information from the client device 1, the matching server 3 associates the client device 1 with the chat room and registers them in the storage unit 17. When the entry request information is received from the client device 1, it is determined whether or not the chat room specified by the received entry request information is registered in the storage unit 17, and the chat room is registered in the storage unit 17. If it is determined, the client device 1 is registered in the storage unit 17 in association with the chat room. When it is determined that the chat room is not registered in the storage unit 17, the client device 1 and the chat room are associated with each other and registered in the storage unit 17. The matching server 3 associates with one chat room. The execution of chat by transmitting and receiving message data is controlled between the plurality of registered client apparatuses 1.

  When the matching server 3 receives the exit request information, the matching server 3 deletes the registration of the client device 1 associated with one chat room specified by the exit request information. Further, when the client apparatus 1 is not registered at all for one registered chat room, the registration of the one chat room is deleted.

  That is, each matching server 3 opens a chat room in response to a setting request (participation request) from the client device 1 by executing a chat management program to be described later, and enters an entry request (entry request from each client device 1). ) Is permitted to enter (participate) the client terminal 1 in the chat room, and the transmission / reception of message data (text data) between the client devices 1 entering the chat room is relayed. Further, the matching server 3 deletes the chat room when all the client devices 1 leave the open chat room. Furthermore, when the matching server 3 receives an entry request from the client device 1 for the already deleted chat room, the matching server 3 opens the chat room again. That is, each matching server 3 has only an active chat room in which one or more client devices 1 are entering, and there is no inactive chat room in which the client device 1 is not entering at all. The message server 4 also relays transmission / reception of message data (text data) between the client devices 1, but its function is different from the matching server 3 in that it does not require entry into the chat room. In the following description, message data transmitted / received to / from the matching server 3 is referred to as chat data, and is distinguished from message data transmitted / received to / from the message server 4.

  Each client device 1 is connected to the controller 20 and the monitor device 10 via a connection cable 19. The controller 20 is an operation terminal operated by the user, and supplies an operation signal corresponding to the operation from the user to the client device 1. The controller 20 may be any input device that can supply an operation signal (input signal) according to a user's operation to the client device 1, and various types such as a keyboard type and a game controller can be applied. .

The monitor device 10 displays an image based on the video signal supplied from the client device 1. At the start of the chat (when entering the chat room), a room selection screen is displayed on the monitor device 10. On the room selection screen, images showing chat rooms that can be selected by the user are arranged and displayed. When the user enters a chat room and is performing a chat, a chat screen corresponding to the chat room is displayed. The chat screen is switched between a display state and a non-display state according to an instruction from the user. When the chat screen is hidden and other screens are displayed, when another client device 1 enters or leaves the chat room being entered, or chat data from another client device 1 Is transmitted, a chat information notification screen for notifying them is displayed over the other screen.
<Main configuration of client device>
Next, a main configuration related to the present invention among the internal configurations of the client apparatus will be described with reference to FIG.

  The client device 1 includes a communication unit 80, a chat execution unit 13, a display control unit 14, and a storage unit 15, which are connected via a bus. In accordance with the chat execution program stored in the storage unit 15, the client device 1 performs the following processes (opening request processing, entry request processing, leaving request processing, chat execution processing, invitation transmission processing, invitation reception processing, room selection screen display Process, chat screen display process, etc.). In the following description, the user specifying information is unique information that can identify the client device 1 and is stored in the storage unit 15. As the user identification information, for example, a unique user ID given in advance to the user of the client device 1, a device ID given in advance to the client device 1, a user's mail address, or the like is used.

  A friend management table for registering friends is set in the storage unit 15. In the friend management table, user identification information and user attribute information of other users (friends) who can use the chat system SYM are stored in association with each other. When the user operates the controller 20 and makes a predetermined input, the user identification information is registered in the friend management table. The user attribute information includes information such as the user's e-mail address, the user's nickname, and image data of the avatar selected by the user.

  The opening request process is executed when the controller 20 receives a predetermined operation input for instructing a new opening of a chat room from the user, and the client device 1 receives an operation signal (room opening instruction signal) from the controller 20. The establishment request process includes a server determination process and a room information determination process. In the server determination process, the chat execution unit 13 determines server selection basic information (server key) according to a predetermined method, and selects a matching server 3 that opens a chat room among the plurality of matching servers 3A, 3B, and 3C. It is determined by determining from the server selection basic information according to a predetermined predetermined correspondence. In the room identification information determination process, the chat execution unit 13 determines room identification information (room key) unique to the chat room according to a predetermined method.

  The chat execution unit 13 generates opening request information including its own user identification information, and the communication unit 80 transmits the generated opening request information to the determined matching server 3. Further, the chat execution unit 13 generates setting request information including the determined room specifying information and its own user specifying information, and the communication unit 80 transmits the generated setting request information to the determined matching server 3. Send. The establishment request process ends when the communication unit 80 receives the room identification information (room ID) of the established chat room from the matching server 3.

  The chat execution unit 13 stores the determined room specifying information and the server selection basic information in the storage unit 15 in association with each other. The chat execution unit 13 stores chat room establishment information as chat history information in association with room specifying information. The chat room establishment information includes information indicating the establishment date and time of the chat room. The opening date and time of the chat room indicates the execution time of the opening request process such as when the opening request process starts and when the opening request process ends (when the communication unit 80 receives room identification information from the matching server 3). Any date and time can be specified. The timing for storing the opening information is preferably at the end of execution of the opening request process. The client device 1 acquires various information indicating the date and time from its own internal clock.

  The predetermined method for determining the server selection basic information may be any method that can determine the specific server selection basic information. For example, from the basic data that combines the user identification information and the time at which the opening request processing is started. A method of calculating a hash value using a predetermined hash function can be used. In this case, the hash value obtained by the calculation is the server selection basic information. By combining the time with the basic data on which the hash value is calculated, it is possible to avoid the inconvenience that duplicate server selection basic information is generated in the same client device 1.

  The predetermined correspondence relationship in which one matching server 3 for establishing a chat room is selected and determined from a plurality of matching servers 3A, 3B, 3C is that chat rooms are evenly distributed to a plurality of matching servers 3. It is only necessary to be a relationship to be allocated (a relationship in which one of the unique server IDs assigned to each matching server 3 and the determined server selection information correspond equally). For example, server reference basic information (the hash value) A hash function set so that one server ID can be calculated at random can be used. In this case, the server ID of the matching server 3 that opens the chat room is calculated as a hash value of the server reference basic information.

  The predetermined method for determining room-specific information specific to a chat room may be any method that can determine specific room-specific information. For example, the predetermined method is determined from basic data obtained by combining user-specific information and a server ID. A method of calculating a hash value using a hash function of In this case, the hash value obtained by the calculation becomes room specifying information.

  The predetermined correspondence for selecting and determining the matching server 3 is updated according to the increase or decrease in the number of matching servers 3. For example, when the administrator or the like of the server device 2 increases or decreases the number of matching servers 3, the server device 2 transmits server number update information including correspondence (new) that matches the increased or decreased server number to each client device 1. To do. The client device 1 that has received the server number update information rewrites the stored correspondence (old) with the received correspondence (new).

  In the opening request process, the chat execution unit 13 receives an input of the room name of the chat room to be opened from the user via the controller 20, and stores the input room name in association with the room specifying information as room attribute information. When no room name is input from the user, a preset default room name is stored.

  The room entry request process is executed when the controller 20 receives a predetermined operation for designating a chat room and instructing entry from the user, and the client apparatus 1 receives an operation signal (room entry instruction signal) from the controller 20. In the room entry request process, the chat execution unit 13 reads the server selection basic information and the room identification information corresponding to the designated chat room from the storage unit 15, as in the case of the opening request process (the read server selection basic information). The matching server 3 in which the chat room is established is specified in accordance with the above-described predetermined method.

  The chat execution unit 13 generates room entry request information including the user identification information and the read room identification information, and the communication unit 80 transmits the generated room entry request information to the identified matching server 3. The room specifying information is used for searching for a chat room in the matching server 3. The entry request process is terminated when the communication unit 80 receives entry completion information for itself from the matching server 3.

  On the other hand, if the designated chat room has already been deleted, the matching server 3 does not extract the chat room and fails to enter the room. When entry into the room fails, the communication unit 80 receives entry failure information indicating that entry into the chat room has failed from the matching server 3. When the communication unit 80 receives the entry failure information, the process proceeds to the opening request process. That is, the chat execution unit 13 generates establishment request information including its own user identification information, and setting request information including the room identification information of the designated chat room and its own user identification information. The generated opening request information and setting request information are transmitted to the matching server 3 that transmitted the room entry request information.

  The chat execution unit 13 stores entry information (self entry information) indicating entry into the chat room in association with the room specifying information as chat history information. The self entry information includes information indicating the date and time when the user enters the chat room. The entry date and time for entering the chat room includes the time when the entry request process is started and the end of the entry request process (when the communication unit 80 has received its own entry completion information from the matching server 3). Any date and time that specifies the entry time may be used. The timing for storing the own room entry information is preferably at the end of execution of the room entry request process.

  In this embodiment, when the opening request process is completed, the room entry request process is executed without requiring an operation input from the user. In this case, since the chat room has already been specified in the opening request process, the above process for specifying the matching server 3 and the chat room can be omitted. Further, the room entry request process is a process executed independently for each of the plurality of chat rooms, and the client device 1 enters another chat room while maintaining entry to one chat room. be able to.

  The leaving request process is executed when the controller 20 receives a predetermined operation for designating a chat room and instructing to leave, from the user, and the client device 1 receives an operation signal (leaving instruction signal) from the controller 20. In the exit request process, the chat execution unit 13 generates exit request information including user identification information and a server ID, and the communication unit 80 transmits the generated exit request information to the matching server 3. The exit request process ends when the communication unit 80 receives exit completion information for itself from the matching server 3.

  The chat execution unit 13 stores exit information (own exit information) indicating that the user has exited the chat room in association with the room specifying information as chat history information. The self-exit information includes information indicating the date and time when the user leaves the chat room. The timing of storing the exit date / time and the exit information from the chat room is not only when the exit request process starts, but also when the exit request process ends, or when the communication unit 80 receives its own exit completion information from the matching server 3. Any date and time may be used as long as it specifies when to leave the chat room.

  The chat execution process is continuously executed while entering the chat room (from the end of the entry request process to the end of the exit request process). In the chat execution process, the chat execution unit 13 generates chat data based on an operation signal from the controller 20. The chat execution unit 13 generates transmission data including the generated chat data and the user identification information in response to a transmission instruction from the user via the controller 20, and the communication unit 80 The generated transmission data is transmitted to the chat room (matching server 3) designated by the user.

  The communication unit 80 is transmitted from another person's entry completion information indicating entry of another client device 1 into the chat room, another person's exit information indicating exit of the other client device 1 from the chat room, or transmitted from the matching server 3. Received data including the chat data (received chat data) and the user specifying information of the client device 1 indicating each execution subject is received from the matching server 3.

  The chat execution unit 13 uses, as chat history information, the other person's entry completion information, the other person's exit information, and the received message information indicating the received chat data received by the communication unit 80, and the user identification information corresponding thereto. Store in association with specific information. The other person's entry completion information, the other person's exit completion information, and the received message information that are stored include information indicating the reception date and time, respectively.

  In the invitation transmission process, the controller 20 receives a predetermined operation for inviting another user (another client device 1) to the chat room from the user, and the client device 1 receives an operation signal (invitation instruction signal) from the controller 20. To be executed. In the invitation transmission process, the chat execution unit 13 reads the server selection basic information, the room identification information, and the room attribute information associated with the chat room (room identification information) designated by the user from the storage unit 15, and enters the chat room. Invitation information including message data indicating invitation, own user specifying information, server selection basic information, room specifying information, and room attribute information is generated. The communication unit 80 transmits the generated invitation information to the other specified client device 1 via the message server 4. In addition, you may memorize | store the user specific information of the other client apparatus 1 which transmitted invitation information in association with room specific information as room attribute information or chat history information.

  The invitation receiving process is executed when the communication unit 80 receives invitation information from another client device 1 via the message server 4. In the invitation reception process, the chat execution unit 13 associates the server selection basic information, the room identification information, the user identification information, and the room attribute information included in the invitation information received by the communication unit 80 with each other, and stores the storage unit 15. To remember. The user specifying information is stored as room attribute information.

  The room selection screen display process is executed when the controller 20 receives a predetermined operation for instructing display of the room selection screen from the user. In the room selection screen display process, the display control unit 14 displays a room selection screen on the monitor device 10. On the room selection screen, images (room-corresponding images) indicating chat rooms that can be selected by the user are arranged and displayed. Each room-corresponding image includes at least one information of chat history information and room attribute information stored in association with each chat room (room specifying information). When the user operates the controller 20 to select and specify one chat room (one of the displayed room-corresponding images), the entry request process for the specified chat room is executed.

  The chat screen display process is executed by selecting and specifying one chat room in a state where the room selection screen is displayed. In the chat screen display process, the display control unit 14 displays a chat screen on the monitor device 10. The chat screen includes at least a part of information including the latest information (information with late date and time) among the chat history information stored in association with the designated chat room, and at least a room name among the room attribute information. Part information is displayed. Chat history information is displayed in chronological order from the latest information.

  The display control unit 14 switches the chat screen between a display state and a non-display state according to an instruction from the user via the controller 20. When the non-display state is instructed, the chat screen display process is temporarily interrupted and the chat screen is not displayed. However, since the chat screen display process is not ended, but temporarily interrupted, the chat screen is displayed immediately upon receiving an instruction to switch to the display state.

  When the chat screen is set to the non-display state and other screens are displayed, if room attribute information is added for the chat room that is entering the room (the room attribute information is newly stored in association with the room identification information) Then, the display control unit 14 displays a chat information notification screen for notifying the added room attribute information on the other screen.

Subsequently, the communication unit 240 receives the opening request information and the setting request information from the client device 1, and the chat management unit 16 executes the room opening process.

  The leaving process is executed when the communication unit 240 receives the leaving request information from the client device 1. In the leaving process, the chat management unit 16 extracts and deletes the received user specifying information from the user specifying information associated with the room ID included in the leaving request information. Due to the deletion of the user specific information, the client device 1 has left the chat room. The chat management unit 16 generates exit information, and the communication unit 240 associates the generated exit information with all the client devices 1 registered in association with the chat room (the client device 1 that has made the exit request). Including).

  When all the client devices 1 leave the chat room (when all the user specific information associated with the registered room specific information is deleted), the chat management unit 16 relates to the chat room (room specific information). All information (room identification information and all data stored in association with this) is deleted from the room information registration table. By deleting all related information, the chat room is deleted.

The chat management process is continuously executed while the room identification information is registered in the room information registration table (while the client device 1 entering the chat room exists). In the chat management process, when the communication unit 240 receives transmission data including room specifying information corresponding to the chat room from the client device 1, the chat management unit 16 registers in association with the room specifying information received by the communication unit 240. The transmission data is transmitted to all the client devices 1 associated with the user identification information. Note that the chat management unit 16 does not transfer the received transmission data as it is, and determines whether or not inappropriate expressions or sentences are included in the message data included in the transmission data. If it is determined that a sentence is included, the corresponding part may be replaced with an irrelevant character or symbol (for example, x) and transmitted to the client device 1.
<Example of matching server>
Next, an example of the matching server 3 in which the configuration of FIG. 4 is implemented will be described with reference to FIG.

  The matching server 3 includes a CPU 200, a ROM 210, a RAM 220, an HDD (Hard Disc Drive) 230, a communication unit 240, and the like, and these are connected via a bus. The CPU 200 functions as the chat management unit 16, and the RAM 220 and the HDD 230 function as the storage unit 15.

  The ROM 210 stores an operating system and various programs for controlling each part of the server device 2. The CPU 200 reads the operating system stored in the ROM 210 into the RAM 210 when the server apparatus 2 is activated, and controls the operation of each unit of the server apparatus 2 by executing the read operating system.

  The HDD 230 stores various data and various application programs such as a program (chat management program) for realizing chat. CPU 200 reads the chat management program stored in HDD 230 into RAM 220 and executes the read chat management program.

The communication unit 240 controls data communication via the Internet 30 under the control of the CPU 200.
<Message server configuration>
The message server 4 includes a CPU, a ROM, a RAM, an HDD (Hard Disc Drive), a communication unit, a bus, and the like, and the basic configuration is the same as that of the matching server 3, and thus detailed description thereof is omitted. To do.
(2) Operation Next, an example of an operation executed in the chat system SYS will be described.

  In the client device 1, an unillustrated power supply is turned on, and a program such as an operating system stored in the ROM 44 is read out and executed by the CPU 41 into the main memory 43, and an instruction is input by the user, whereby the ROM 44 and the optical disc are input. Various programs read to the main memory 43 from the optical disk mounted on the apparatus 71 are executed by the CPU 41, and various functions described in the above-described configuration column are realized.

  The matching server 3 is powered on (not shown), and various programs such as an operating system stored in the ROM 210 are read out to the RAM 220 by the CPU 200 and executed, thereby realizing the various functions described in the above-described configuration column. The The same applies to the message server.

  When a chat is started using the chat system SYS, the user (1) opens a chat room by himself and invites other users, and (2) enters a chat room invited by another person. Is possible.

In the following description, when the user A of the client device 20A opens a chat room and invites the user B of the client device 20B to the chat room, and the invited user B enters the chat room (joins the chat). The various settings are as follows. The user specifying information is a user ID. The server key (server selection basic information) is a hash value calculated from the combination of the user ID and the start time of the opening request process. The server ID of the matching server 3 that opens the chat room is calculated as a hash value of the server key. The room key (room specifying information) is a combination of the time (for example, the start time of the opening request process) and the room ID received from the matching server 3.
<Open chat room / Invite friends>
Operations of the client device 20A and the matching server 3 when the user A newly opens a chat room RA will be described with reference to FIGS.

  As shown in FIG. 6, when the user A operates the controller 20A to give a predetermined input for instructing a new establishment of the chat room RA, and the client apparatus 1A receives a room establishment instruction signal from the controller 20 (step S10), The client device 1A starts the opening request process.

  In the opening request process, the reception time Ta of the room opening instruction signal is acquired from the internal clock of the client device 1A, the user ID (A) of the user A is read from the storage unit 15A, the character string of the user ID (A) and the time Ta By generating a basic data (user ID (A) Ta) and using a preset hash function (hashA), the hash value (from the basic data (user ID (A) Ta)) ( hashA (user ID (A) Ta)) is calculated (step S11). This hash value (hashA (user ID (A) Ta)) functions as a server key SKa that can be used when selecting one matching server 3 from the plurality of matching servers 3 without any bias.

  Next, the hash value (hashB (SKa)) of the server key SKa is calculated using a preset hash function (hashB) (step S12). This hash value (hashB (SKa)) is the server ID of one matching server 3 selected without any bias from the plurality of matching servers 3. In this example, it is assumed that the calculated server ID (A) is the server ID of the matching server 3A and the matching server 3A is selected.

  Next, the establishment request information including the user ID (A) is transmitted to the matching server 3A (step S13).

  The matching server 3A executes room opening processing in response to the reception of the opening request information (Step S20) (Step S21). In the room opening process, a room ID is generated, and the generated room ID is newly registered in the room information registration table. The matching server 3A transmits the generated room ID to the client device 1A (step S22). At this time, the room ID is transmitted in a state associated with the received opening request information so that the client apparatus 1A can determine that the room ID corresponds to the opening request information.

  The client device 1A that has received the room ID sets a room key RKa unique to the chat room RA by combining the received room ID and time (step S15).

  Next, the setting request information including the room key RKa and the room ID is transmitted to the matching server 3A (step S15).

  When the matching server 3A receives the setting request information (step S16), the matching server 3A associates the room key RKa included in the received setting request information with the established chat room RA (the room ID included in the received setting request information). Register in the information registration table (step S17). Thereby, the establishment of the chat room RA in the matching server 3A (the above opening process and registration process) is completed, and the matching server 3A generates the opening completion information and associates it with the room ID and transmits it to the client apparatus 1A (step S18). ).

  The client apparatus 1A ends the opening request process upon receiving the opening completion information (step S19).

  The client device 1A executes a room entry request process following the opening request process, and enters the chat room RA. Details of the entry / exit request processing will be described later.

  The client device 1A stores the server key SKa calculated in step S11 and the room key RKa set in step S14 in the storage unit 15 in association with each other. Further, information indicating the opening date and time of the chat room RA is stored in association with the room key RKa.

  Further, in the opening request process, the client device 1A causes the monitor device 10A to display the room name input screen 100 of the chat room RA, for example, as shown in FIG. On the room name input screen 100, a sentence 101 such as “Please enter a chat room name”, a room name input field 102, and a confirmation icon 103 are displayed. When the user A operates the controller 10A to set a cursor in the room input field 102 and inputs a room name, moves the cursor to the fixed icon 103 and presses a predetermined YES button, the client apparatus 1A is input. The room name is stored in association with the room key RKa. If the user A sets the cursor on the confirmed icon 103 and presses the YES button without inputting the room name, the client device 1A stores the default room name.

  When the input of the room name is completed, the client device 1A switches the display of the monitor device 10A from the room name input screen 100 to, for example, an inviter selection screen 110 as shown in FIG. On the inviter selection screen 110, a sentence 111 such as “Please select a friend to invite”, a nickname (such as Hanako, Taro, Jiro, and Pochi) 112 of each user registered as a friend, and an avatar 113 of each user Then, a check box 114 for inputting the presence / absence of selection, a number display column 115 indicating the total number of selected persons, and a confirmation icon 116 are displayed. The nickname 112 and the avatar 113 are read from the friend management table of the storage unit 15A and arranged side by side for each user. One check box 114 is provided for each user, and the default is a non-selection display of a rectangular frame (outline). When the user A operates the controller 10A to move the cursor up and down, sets the cursor to a desired user, and presses the YES button, the display of the corresponding check box 114 is switched. In the case of non-selection display, the display is switched to selection display (for example, a filled state). In the case of selection display, the display is switched to non-selection display. In the number-of-persons display column 115, the number of users selected as invitees is displayed by increasing / decreasing according to the selection / non-selection switching of each check box 114. FIG. 8 shows a state in which only the nickname “Taro” is selected and the number “1” in the “Number of people display field” is displayed. When the user A selects one or more users who want to invite to the chat room RA (changes the corresponding check box 114 to the selection mode), sets the cursor on the confirmation icon 1116 and presses the YES button, the controller 20A sends the client An invitation instruction signal is transmitted to apparatus 1A. The client device 1A that has received the invitation instruction signal determines that there has been an invitation transmission instruction, determines the user to be invited, and starts the invitation transmission process. In this example, it is assumed that the user B is confirmed as an invitation target.

  When the invitation transmission process is started, the client apparatus 1A, as shown in FIG. 9, stores the server key, room key, and room name associated with the chat room (room identification information) designated by the user A from the storage unit 15. Read (step S30). In the invitation call processing at the time of opening the chat room, the chat room RA requesting the opening becomes the chat room designated by the user A, and the server key SKa (step S11 in FIG. 6) and the room key RKa (step S14 in FIG. 6). ) And the input room name.

  Next, the client apparatus 1A generates and generates message data indicating invitation to the chat room RA, own user ID (A), read server key SKa, room key RKa, and room name. The invitation information is transmitted to the message server 4 with the client device B as the destination (step S31).

  When the message server 4 receives the invitation information from the client device 1A, the message server 4 transmits it to the client device 1B (step S32).

The client device 1B receives the invitation information (step S33) and executes an invitation reception process. That is, the server key SKa, room key RKa, user ID (A), and room name included in the received invitation information are associated with each other and stored in the storage unit 15B (step S34).
<Entering chat room>
Operations of the client device 20B and the matching server 3 when the user B enters the chat room RA will be described with reference to FIGS.

  When entering the chat room RA invited by the user A, the user B operates the controller 20B to perform a predetermined input in order to select and specify the chat room RA from among the chat rooms that the user A can enter. A room selection screen 120 as shown in FIG. 10 is displayed on the monitor device 10B.

  On the room selection screen 120, room-corresponding images 121 indicating chat rooms that can be selected by the user B are arranged in the vertical direction and displayed. The room corresponding images 121 are classified and sorted based on room attribute information or chat history information associated with the chat room.

  In the example of FIG. 10, five chat rooms can be selected, and five room-corresponding images 121a to 121e are arranged in the vertical direction. The room-corresponding image 121 includes the room-corresponding images 121a and 121b of the chat room currently entered (participating), the room-corresponding images 121c and 121d of the new chat room that has been invited but never entered, and the past. It is classified as a chat room 121e that has entered the room but has not yet entered, and is arranged from the top to the bottom in the order of entering, new arrival, and leaving.

  Each room-corresponding image 121a to 121e includes a room name (“movie room”, “waiting room”, “for chatting”, “let's talk while playing games”, “puzzle club”) and a nickname (Jiro, Poti, Ichiro, Hanako, Jiro) are included. The room corresponding images 121a and 121b include an in-room display image 122 indicating that the user is currently in the room, and the room corresponding images 121c to 121e include an in-room display image 123 indicating that the user is currently in the room. In the case of the room-corresponding image 121c of the newly arrived room (the room that has been invited by another user and has not yet entered the room) among the rooms that have been left, the new arrival display image 124 indicating that it is new arrival is displayed as the leaving display image 123. Attached and displayed. These display images 122 to 124 can identify whether the corresponding room is currently in the room, whether it has left the room and is newly arrived (not entered), or has entered the room in the past while leaving the room. If it is what is displayed on, it will not be limited to the above.

  The room-corresponding images 121a and 121b that are currently in the room include the avatar 125 of the last speaker (the user who transmitted the chat data (latest chat data) last received by the client device 1B from the matching server 3), and the last speech. Content of each person (the chat data (latest chat data) received last from the matching server 3 by the client device 1B) is included. When the last speaker is the user B (self), the image data of the user's own avatar registered by the user B in the storage unit 15 is read out and displayed as the last speaker's avatar 125. The chat data from the user (the content of the speech of the user B) received last from the user is displayed as the content of the speech of the last speaker.

  The room corresponding images 121c to 121e include the avatars 126 and 127 of the inviter (the user who transmitted the invitation information), respectively. When the inviter is registered as a friend of the user (user B) (when the user ID of the inviter is stored in the friend management table of the storage unit 15B), the image data of the avatar corresponding to the user ID of the inviter Is read from the friend management table and displayed as the inviter's avatars 126 and 127. In the case of a new arrival room invited from a user who is not registered in his / her friend management table, a user information registration table in which the correspondence between the user ID of the user who uses the chat system SYS, the image data of the avatar, and the nickname is registered. The image information and nickname of the avatar corresponding to the inviter's user ID are acquired from the user registration table via the network and set in advance in a storage unit on the Internet (for example, the storage unit 17 of the matching server 3). It is displayed as an avatar 126 or a nickname. In the case of a room opened by self (user B), the avatar and nickname of user B are displayed as the avatar 127 and nickname of the inviter. The correspondence between the user ID once set and the image data and nickname of the avatar is stored in the storage unit 15B for the chat screen display process.

  When the cursor is moved to the room-corresponding images 121a and 121b, the last message date is displayed. When the cursor is moved to the room-corresponding images 121c and 121d, the reception date and time of the invitation information is displayed. The exit date and time are displayed.

  The user B selects a desired one from the room correspondence images 121 displayed on the room selection screen 120, moves the cursor to the selected room correspondence image 121, and presses the YES button, thereby confirming the selection of the chat room. The controller 20B transmits a room entry instruction signal to the client device 1B. In this example, it is assumed that the chat room RA is selected.

  As shown in FIG. 11, the client device 1B starts the room entry request process by receiving the room entry instruction signal (step S40), and receives the server key SKa and room key RKa corresponding to the chat room RA from the storage unit 15B. As in the case of the opening request process (step S12 in FIG. 6), the server ID is calculated using the server key SKa to identify the matching server 3 that requests entry (step S42). . In this case, since the server key SKa is used, the server ID (A) is calculated as in step S12 of FIG.

  Next, the client device 10B generates room entry request information including its own user ID (B) and room key RKa, and transmits it to the matching server 3A corresponding to the server ID (A) (step S43).

  The matching server 3A starts the room entry process by receiving the room entry request information (step S44). In the room entry process, first, it is determined whether or not the room key RKa included in the received room entry request information is registered in the room information registration table (whether or not the chat room RA exists) (step S45).

  When it is determined that it is registered (when the room key RKa is extracted), the room entry process can be executed, and the user ID (B) is registered in the room information registration table in association with the room key RKa (step S46). ). Registration of the user ID (B) causes the client device 1B to enter the chat room RA, and entry completion information for all client devices 1 (including the client device 1B) registered in association with the chat room Ra. Is transmitted (step S47).

  The client device 1B receives the room entry completion information for itself from the matching server 3 and ends the room entry request process (step S48).

  On the other hand, when it is determined in step S45 that the room key RKa has not been registered because the chat room RA has already been deleted (when the room key RKa cannot be extracted), the entry failure information is sent to the client device 1B. (Step S49).

  The client device 1B that has received the entry failure information moves to the opening request process. That is, the establishment request information including the own user ID (B) and the setting request information including the room RKa of the chat room RA and the own user ID (B) are transmitted to the matching server 3A. Thereby, the chat room RA is established in the matching server 3A, and the client device 1B enters the chat room RA.

  While entering the chat room RA (from the end of the entry request process to the end of the exit request process), the client device 1B continues to execute the chat execution process for the chat room RA. The client device 1B generates chat data based on an operation signal from the controller 20B, and transmits transmission data including the generated chat data and a user ID (B) in response to a transmission instruction from the user via the controller 20B. The generated transmission data is transmitted to the chat room RA of the matching server 3A.

  In addition, the client device 1B may be another person's entry completion information indicating entry of another client device 1 into the chat room RA, another person's exit completion information indicating exit of another client device 1 from the chat room RA, or a matching server. Received data including the chat data (received chat data) transmitted from 3 </ b> A and the user ID of the client device 1 indicating each execution subject is received from the matching server 3. The client device 1B stores the received other person's room entry completion information, the other person's leaving information, the received message information indicating the received chat data, and the corresponding user ID as chat history information in association with the room specifying information. To do. The other person's entry completion information, the other person's exit completion information, and the received message information that are stored include information indicating the reception date and time, respectively.

  Further, the client device 1B entering the chat room RA executes a chat screen display process while the user B is performing a chat, for example, and displays a chat screen 130 as shown in FIG. 12 on the monitor device 10B. .

  The chat screen 130 includes at least a part of information including the latest information (information with a late reception date) among the chat history information stored in association with the chat room RA and at least a room name among the room attribute information. Part information is displayed. Chat history information is displayed in chronological order from the latest information.

  The chat screen 130 in the example shown in FIG. 12 includes a room name display field 132 in which a room name (movie room) is displayed, an avatar and a nickname of a speaker (user who transmitted chat data), and a message content (received chat data). ) Is displayed in chronological order based on the time of speech (reception time), the speech display column 133 in which user B writes the speech (inputs chat data), the number of users entering the room Are displayed, a scroll bar 136 for scrolling the message display field 133, a friend list display icon 137, and a participant list display icon 138.

  When the user moves the cursor to the friend list display icon 137 and presses the YES button, a screen similar to the inviter selection screen 110 shown in FIG. 8 is displayed. Can be invited. When the cursor is moved to the participant list display icon 138 and the YES button is pressed, a list of all users who have entered (participated in) the chat room (for example, a list of nicknames and avatars) is displayed. The

  The chat screen 130 is switched between a display state and a non-display state according to an instruction from the user via the controller 20, and when the non-display state is instructed, the chat screen display process is temporarily interrupted, and the chat screen 130 is displayed. Is not displayed.

  When the chat screen 130 is set to the non-display state and another screen is displayed (for example, when the game is being executed and the game screen is displayed), the room attribute of the chat room that is entering the room When information is added (when the room attribute information is newly stored in association with the room specifying information), a chat information notification screen for notifying the added room attribute information is displayed over the game screen.

For example, as shown in FIG. 13, when a user enters a chat room with a room name “waiting room”, the chat screen is set to a non-display state, and the game screen 140 is displayed, When the nickname "Pochi" says "I understand" (when the message data "I understand" is received in association with the user ID corresponding to the nickname "Pochi"), the chat information containing these information A notification screen 141 is displayed. When the nickname “Hanako” enters the “waiting room”, a chat information notification screen including a sentence “Hanako has joined the waiting room” is displayed. The range and position for displaying the chat information notification screen 141 are preferably as narrow as possible and close to the periphery of the game image 140 so as not to hinder the execution of the game.
<Leaving chat room>
Operations of the client device 20B and the matching server 3 when the user B leaves the chat room RA will be described.

  When the user B designates the chat room RA by operating the controller 20B and instructs to leave, the client apparatus 1B receives the leave instruction signal from the controller 20B, and starts the leave request process. In the leaving request process, the leaving request information including the user ID (B) and the server ID is transmitted to the matching server 3A.

  The matching server 3A that has received the leaving request information starts the leaving process. In the leaving process, the matching server 3A extracts and deletes the received user ID (B) from the user IDs registered in association with the room ID included in the received leaving request information. When the user ID (B) is deleted, the client apparatus 1B leaves the chat room RA. Then, the matching server 3A transmits the exit completion information to all the client devices 1 registered in association with the chat room RA (including the client device 1B that made the exit request).

  When all the client devices 1 leave the chat room RA (when all user IDs registered in association with the chat room RA are deleted), the matching server 3A determines all the information related to the chat room RA (the room key RKa and this). All the data stored in association with is deleted from the room information registration table. By deleting all related information, the chat room RKa is deleted.

  The exit request process in the client device 1B is terminated by receiving the exit completion information for itself from the matching server 3A.

  As described above, the matching server 3 deletes the chat room when all the client devices 1 leave the open chat room. In addition, when the matching server 3 receives an entry request from the client device 1 for the already deleted chat room, the matching server 3 opens the chat room again.

  That is, each matching server 3 has only an active chat room in which one or more client devices 1 are entering, and there is no inactive chat room in which the client device 1 is not entering at all. .

  Therefore, the remaining capacity of the storage unit 15 of the matching server 3 is not compressed due to the presence of an inactive chat room, and the storage capacity required for the storage unit 15 can be minimized. 15 efficient use is possible.

  When the client device 1 requests entry into the chat room, if the chat room is deleted, the client device 1 performs the entry request processing without notifying the user that the chat room has been deleted. Subsequently, an opening request process is executed to open a chat room in the matching server 3 and enter the room. Therefore, the user who uses the chat system SYS does not feel uncomfortable.

  Each client device 1 leaving the chat room calculates the server ID of the matching server 3 in which the chat room exists as a hash value of the server key, and the server ID and hash function used for the calculation are each client device. 1 is the same. Further, the hash function is set so that a plurality of matching servers 3 are selected without bias, and is updated as appropriate according to the increase or decrease of the matching servers 3. That is, even when all the client devices 1 leave the chat room, the matching server 3 is added, the hash function is updated, and the calculated server ID is changed. The server IDs calculated in the device 1 are all changed so as to correspond to the same matching server 3. Therefore, it is possible to efficiently distribute the server load after adding the matching server 3.

  At the start of chatting (when entering a chat room), a room selection screen 120 is displayed on the monitor device 10. On the room selection screen 120, room-corresponding images 121 indicating selectable chat rooms are arranged and displayed. Each room-corresponding image 121 is at least one of chat history information and room attribute information stored in association with each chat room. Contains one piece of information. Therefore, the user can easily grasp the contents of each chat room that can be entered and enter the desired chat room.

  The user can centrally manage chat rooms in which the user can participate on the client device 20 side.

  When the user enters the chat room and is performing a chat, a chat screen 130 corresponding to the chat room is displayed on the monitor device 10. The chat screen 130 displays at least a part of information including the latest information among the chat history information associated with the chat room, and a part of information including at least the room name among the room attribute information. The Therefore, the user of the chat system SYS is the same as when the server device stores all chat history information and manages them centrally, and each client device receives the chat history information from the server device and displays it. You can chat in the same way.

  The chat screen 130 is switched between a display state and a non-display state according to an instruction from the user, and when the chat screen 130 is in a non-display state and another screen (for example, the game screen 140) is displayed, When another client device 1 enters or leaves the chat room, or when chat data is transmitted from another client device 1, the chat information notification screen 141 for notifying them is displayed on the other screen. It is displayed overlaid on the (game screen 140). Therefore, it is possible to easily chat with other users while performing other processing such as a game.

  In the above embodiment, when the client device 1 requests entry into a chat room that does not exist in the matching server 3, the matching server 3 receives the chat room opening request from the client device 1 as a start condition. However, the chat room may be opened with the determination that the matching server 3 does not exist as a start condition.

  The above description of each embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiments, and various modifications can be made even outside the above-described embodiments as long as they do not depart from the technical idea according to the present invention.
