Description

  The present invention relates to a server, a control method thereof, and a control program thereof.

  When there are many users who want to access a server that provides a service, the number of accesses exceeds the limit on the number of people, so not all users can receive the service. In this case, the user's terminal cannot be connected to the server, or a message requesting to reconnect later is simply displayed on the user's terminal. Therefore, the user must repeatedly access the server until the desired service is received and wait for the order of receiving the service.

  With regard to such a waiting order of services provided via a communication network, for example, in Patent Document 1, a service server that provides a service to a user includes a user's waiting room, and the waiting room receives a service from the user. A service providing system that displays a waiting status is disclosed. Also, in Patent Document 2, when the number of requests received from a client terminal exceeds the maximum number of processing of the host computer, the request is registered in a waiting state, and the reception processing according to the number of congestions registered in advance. A request processing method for notifying a client terminal of a waiting time calculated from time is disclosed.

  Limiting the maximum number of servers that can provide a service can prevent the server from freezing even when access is concentrated on the server and sudden communication traffic occurs. However, if the maximum number of processes is limited too much, the user abandons receiving service provision when the waiting queue of the user waiting for service provision becomes long. On the other hand, if there is a queue of users waiting for the provision of a service, the service tends to increase in value. For example, if the service is a shop that provides items in the game, and there is a long waiting queue for users in the shop, the items that can be acquired there are parameters such as the original strength. Is given a new feature of rare and rare value. For this reason, it is preferable to control the waiting queue so as not to become too long while creating a waiting queue of users waiting for the provision of the service by changing the maximum number of users capable of providing the service at the same time. .

  Hereinafter, a server, a control method thereof, and a control program thereof according to the present invention will be described with reference to the drawings. However, it should be noted that the technical scope of the present invention is not limited to these embodiments, but extends to the invention described in the claims and equivalents thereof.

  This server deliberately limits the maximum number of simultaneous provisions indicating the maximum number of users that can provide services simultaneously within the range of its processing capacity, and is less than the maximum number of simultaneous provisions according to the service provision request from the user's terminal Services to users' terminals. When the service provision request is further received when the number of users providing the service reaches the maximum number of simultaneous provisions, this server adds the user information of the user of the terminal to the waiting information (for example, waiting queue). Then, let the user wait for the turn. Then, the number of users included in the standby information is displayed on the terminal of the user who is waiting for the provision of the service to express that the service provided by this server has a standby queue.

  In addition, when the number of users included in the standby information exceeds the upper threshold, the server increases the maximum number of simultaneous provisions so that the number of users waiting for service provision does not exceed a certain number. For example, if the waiting queue is too long and the user is likely to give up providing the service, the maximum number of simultaneous provisions is increased and the number of users waiting for the turn is decreased. Thus, in this server, by changing the maximum number of simultaneous provisions, the length of the user's standby queue for the service to be provided is controlled within a certain range.

  Hereinafter, a case where the server is a server that provides a game to a plurality of users and the service is a service provided in the game will be described as an example. In particular, this service is a shop where the user can get items in the game, or a special stage where the user can challenge in the game, and waiting for the user to wait in order to enter there A case where a column is formed will be described as an example. This service may be a shop or stage that opens during a specific period and allows the user to enter only during that period. However, the service referred to in the present invention is not limited to the one in the game as long as it is provided to the user from the server via the communication network.

  FIGS. 3A to 3C and FIGS. 4A to 4C are diagrams showing examples of screens displayed on the display unit 24. FIG. Here, with reference to FIG. 3 (a) to FIG. 4 (c), an outline of processing of the standby queue related to the service provided by the game system 1 will be described.

  FIG. 3A shows an example of the game progress screen 300. On the game progress screen 300, a normal game screen 302 and a service selection button 304 are displayed. On the normal game screen 302, an image of a game being played by the user is displayed. As the service selection button 304, in FIG. 3A, a “shop a” button, a “stage b” button, and a “stage c” button are displayed. When the user presses any of these buttons, a screen related to the corresponding service is displayed.

  FIG. 3B shows an example of the standby selection screen 320 displayed when the “shop a” button is pressed among the service selection buttons 304 in FIG. On the standby selection screen 320, a service display window 322, an information display window 324, an “arrange” button 326, and an “unaligned” button 328 are displayed.

  In the service display window 322, a message regarding the waiting queue of the user waiting for entry to the shop a is displayed. In the information display window 324, the remaining time (1 hour 32 minutes) until the service end time of the shop a is displayed in the upper row, and the number of users waiting to enter the shop a (30 people) is displayed in the lower row. Thus, by displaying the number of users waiting for the turn, the user can recognize how popular the shop a is based on the number of users. In this game, if your turn does not come by the service end time, you cannot enter shop a even if you are in the wait queue, but if you are in the wait queue by the service end time, It may be possible to enter even after the service end time has elapsed. The shop a may be a limited shop where the quantity of items to be sold is limited. In this case, the upper part of the information display window 324 displays the remaining number of the limited number instead of the remaining time. May be.

  When the user presses the “Arrange” button 326, the user is added to the waiting queue as the 31st user waiting for entry to the shop a. On the other hand, when the user presses the “Do not line up” 328 button, the user does not join the waiting queue, and, for example, the game progress screen 300 of FIG. 3A is displayed again.

  If there is no waiting queue in shop a, it is not necessary to wait in turn, so when the “shop a” button is pressed on the game progress screen 300 in FIG. 3A, the waiting in FIG. The selection screen 320 is not displayed, but a service provision screen 420 shown in FIG.

The maximum simultaneous provision number is the maximum number of users who can simultaneously provide the service, and may be increased or decreased as appropriate. The length of the waiting queue is the number of users included in the waiting queue of users who are waiting to provide the service. The upper threshold and the lower threshold are thresholds set for the length of the waiting queue of the user who waits for the provision of the service. The provision period is a period during which the user can receive the service. Although the provision period is set for all the services of S001 to S003 shown in FIG. 6A, the service provided by the server 3 may have no period limitation, such as a quantity limitation service or a member limitation service. There may be.

  FIG. 6B shows an example of a user table. In the user table, for each user registered in the game system 1, the user ID of the user, the name, the points possessed by the user, and the like are stored. The user ID stored in the user table is an example of user information. Since the user ID only needs to be able to identify the user, the user ID may be the ID, telephone number, mail address, or the like of the user's portable terminal 2.

  FIG. 6C shows an example of the standby information table. In the standby information table, for each service included in the service table, the user ID of the user who requested the provision of the service is stored in the order in which the request was made. The standby information table is implemented with a data structure such as an array or a linked list. This standby information table is an example of standby information, and includes information on the number of users waiting for service provision and the ranking of each user. Note that the length of the above-described queue is the number of users included in the standby information table for the target service. In addition, the service in the stage c whose service ID is S003 has a standby queue length of 0 as shown in FIG. 6A, and therefore no user ID is stored in the standby information table.

  The server processing unit 33 includes one or a plurality of processors and their peripheral circuits. The server processing unit 33 is, for example, a CPU, and comprehensively controls the overall operation of the server 3. Based on a program (for example, an operating system program, a driver program, and an application program) stored in the server storage unit 32, the server processing unit 33 performs various processes of the server 3 in an appropriate procedure. Controls the operation of the server communication unit 31 and the like. Further, the server processing unit 33 can execute a plurality of programs (such as application programs) in parallel.

  The server processing unit 33 includes a server control unit 331, an entrance control unit 332, an exit control unit 333, a service providing unit 334, a standby information management unit 335, and a maximum number setting unit 336. Each of these units is a functional module realized by a program executed by a processor included in the server processing unit 33. Alternatively, each of these units may be mounted on the server 3 as firmware.

  The server control unit 331 controls the operation of the server 3 and appropriately instructs the entrance control unit 332, the exit control unit 333, and the like to execute processing. Specifically, when the server control unit 331 receives a service provision request from the mobile terminal 2 via the server communication unit 31, the server control unit 331 instructs the entrance control unit 332 to execute the process. When the server control unit 331 receives a service end request from the mobile terminal 2 via the server communication unit 31, the server control unit 331 instructs the exit control unit 333 to execute the process. When the server control unit 331 receives another request from the portable terminal 2 via the server communication unit 31, the server control unit 331 executes the process and controls the progress of the game.

  When the server control unit 331 receives a service provision request via the server communication unit 31, the admission control unit 332 receives a user (from which information is included in the service provision request, for which the target user has received the service provision ( Hereinafter, it is determined whether or not the user is “rank 0 user”. In the case of a user of rank 0, the entrance control unit 332 stores the user ID included in the received service provision request in the service table as a user who is providing the service, and instructs the service provision unit 334 to execute the process. .

  If the received service provision request is not from a rank 0 user, the admission control unit 332 refers to the service table using the service ID included in the service provision request as a key, The number of provisions, the number of users who are providing services, and the length of the waiting queue are acquired. Then, the entrance control unit 332 determines whether or not the acquired number of users who are providing services is less than the maximum number of simultaneous offers. When the number of users who are providing services is less than the maximum number of simultaneous offers, the entrance control unit 332 stores the user ID included in the received service provision request in the service table as a user who is providing services, and provides services. The unit 334 is instructed to execute processing.

  When the number of users who are providing services is equal to or greater than the maximum number of simultaneous offers, the entrance control unit 332 acquires the user's mobile terminal 2 having the user ID included in the service provision request via the server communication unit 31. The length of the waiting queue (the number of users waiting for service provision) is transmitted. In response to this, when a service stop request is received from the mobile terminal 2 of the user, the admission control unit 332 stops processing related to the provision of the service to the user. In addition, when an immediate entrance request is received from the mobile terminal 2 of the user, the entrance control unit 332 instructs the service providing unit 334 to execute the process regardless of the number of users who are providing the service. In addition, when a waiting queue addition request is received from the mobile terminal 2 of the user, the entrance control unit 332 instructs the standby information management unit 335 to execute processing.

  When the server control unit 331 receives the service end request via the server communication unit 31, the exit control unit 333 refers to the service table using the service ID included in the service provision end request as a key and stores the target service. The same user ID included in the service termination request is deleted from the “user ID during service provision”. At this time, the exit control unit 333 acquires, from the service table, the length of the queue for the target service, the number of users who are providing services, and the maximum number of simultaneous offers. When the length of the waiting queue is not 0 (that is, there is a user waiting for service provision), and the number of users who are providing the service is less than the maximum number of simultaneous provisions, the exit control unit 333 The standby information management unit 335 is instructed to execute the process.

  In response to a service provision request from the mobile terminal 2, the service providing unit 334 provides a service to the mobile terminals 2 having the maximum number of simultaneous provisions or less. However, the service providing unit 334 responds to a service provision request from the mobile terminal 2 of the user who has acquired a specific game medium, regardless of the number of users who are providing the service. For example, when the server control unit 331 receives an immediate admission request from the portable terminal 2 of the user who has acquired an immediate admission ticket by consuming the points he owns, the service providing unit 334 may be able to A service is provided to the mobile terminal 2 of the user. When providing the service, the service providing unit 334 exchanges data necessary for the service with the service processing unit 253 of the target mobile terminal 2 via the server communication unit 31, and performs processing related to the service to the service processing unit 253. Let it run.

  When the standby information management unit 335 receives a service provision request from the mobile terminal 2 that does not provide the service and the number of users who are providing the service is equal to or greater than the maximum number of simultaneous provisions, the user included in the service provision request Add the ID to the standby information table. That is, the standby information management unit 335 keeps the queue state by adding, to the standby information table, the user ID of the user who cannot receive the service due to the limitation of the maximum number of simultaneous provisions.

  In addition, the number of users who are providing services is maximized at the same time when a service termination request is received from the mobile terminal 2 via the server communication unit 31 or the maximum number setting unit 336 increases the maximum number of simultaneous provisions. When the number is less than the number provided, the standby information management unit 335 deletes the user ID of the user with the lowest rank (minimum) for the target service from the standby information table. Then, the standby information management unit 335 transmits, via the server communication unit 31, to the user's mobile terminal 2 a notification indicating that the order in which the user is to receive the service has come. In addition, the standby information management unit 335 reduces and updates the order of each user ID included in the standby information table for the target service, and the user's mobile terminal 2 corresponding to each user ID is updated via the server communication unit 31. Send the number of users in the current queue and the new ranking.

  The maximum number setting unit 336 increases the maximum simultaneous provision number when the number of users included in the standby information exceeds the upper limit threshold. For the upper limit threshold of the number of users included in the standby information and the maximum number of simultaneous provisions, an initial value having a margin within the processing capacity of the server 3 is set in advance for each service and stored in the server storage unit 32. That is, in the server 3, initially, the number of users who can be processed simultaneously is deliberately limited, and the user ID of a user who cannot receive the service due to the limitation is added to the standby information table, thereby waiting for the service provision. It expresses that the waiting queue is completed. Then, when the number of users included in the standby information table exceeds the upper limit threshold, the maximum number setting unit 336 controls the number of users waiting for service provision within a certain range by increasing the maximum simultaneous provision number, Make sure that the queue is not too long.

  In addition, if there is a waiting queue for a user waiting for the provision of a service, the service tends to have a high value. Therefore, it is preferable that a waiting queue having a certain length is provided for each service. Therefore, the maximum number setting unit 336 decreases the maximum simultaneous provision number when the number of users included in the standby information is less than the lower limit threshold. The lower threshold is also set in advance for each service as a value equal to or lower than the upper threshold and stored in the server storage unit 32. Note that an upper limit threshold and a lower limit threshold may also be provided in the fluctuation range of the maximum number of simultaneous provisions by the maximum number setting unit 336.

  The maximum number setting unit 336 may increase the maximum simultaneous provision number according to the difference between the number of users included in the standby information and the upper limit threshold. For example, when the number of users included in the standby information increases by one, the maximum number setting unit 336 may increase the maximum simultaneous provision number by one more. Alternatively, for example, the maximum number setting unit 336 may increase the maximum simultaneous provision number by 10% if the number of users included in the standby information increases by 10% from the upper limit threshold.

  Similarly, the maximum number setting unit 336 may decrease the maximum number of simultaneous provisions according to the difference between the number of users included in the standby information and the lower limit threshold. For example, the maximum number setting unit 336 may reduce the maximum simultaneous provision number by one more when the number of users included in the standby information is decreased by one. Alternatively, for example, the maximum number setting unit 336 may reduce the maximum simultaneous provision number by 10% if the number of users included in the standby information is reduced by 10% from the lower limit threshold.

  In addition, the number of simultaneous simultaneous provisions indicating the surplus provision capability of the server 3 is stored in the server storage unit 32 in advance, and the maximum number setting unit 336 increases the maximum number of simultaneous provisions within a range equal to or less than the number of simultaneous simultaneous provisions. May be. The free simultaneous provision number is the remaining number that the server 3 can allocate to the maximum simultaneous provision number of each service, and corresponds to a value indicating the limit of the processing capability of the server 3. In addition, when the maximum number setting unit 336 increases the maximum number of simultaneous provisions within a range equal to or less than the number of simultaneous simultaneous provisions, the number of simultaneous simultaneous provisions is increased according to the decrease in the maximum number of simultaneous provisions, and the value May be updated.

  Alternatively, the maximum number setting unit 336 does not increase the maximum number of simultaneous provisions when the number of users included in the standby information exceeds the upper limit threshold, but even when the number of users is between the upper limit threshold and the lower limit threshold The maximum simultaneous provision number may be increased by an increase amount corresponding to the number of users included in the standby information. For example, assume that the upper limit threshold of the number of users included in the standby information is 800, the lower limit threshold is 500, and the length of the standby queue is controlled within the range of 500 to 800. At this time, for example, when the number of users included in the standby information exceeds 500, the maximum number setting unit 336 increases the maximum simultaneous provision number by 0.5 each time the number of users increases by one, and the maximum simultaneous provision number The increase amount may be increased as the number of users approaches 800. For example, as the number of users included in the standby information approaches 800, the maximum number setting unit 336 increases the increase in the maximum number of simultaneous provisions when the number of users included in the standby information increases by one by 0.5. People, 0.6 people, 0.7 people,... In this way, the maximum number setting unit 336 slows down the speed at which the length of the waiting queue increases, so that the number of users included in the waiting information does not exceed the upper limit threshold of 800 people. Good.

  Similarly, the maximum number setting unit 336 does not decrease the maximum simultaneous provision number when the number of users included in the standby information is less than the lower limit threshold, but the number of users is between the upper limit threshold and the lower limit threshold. Even at this time, the maximum number of simultaneous provisions may be reduced by an amount corresponding to the number of users included in the standby information.

  Note that the service providing unit 334 responds to a service providing request received within a predetermined period from the mobile terminal 2 of the user whose user ID has been deleted from the standby information table (user with rank 0). A service may be provided to the mobile terminal 2. In this case, the standby information management unit 335 stores in the server storage unit 32 the time when the order in which the user receives service provision comes in association with the target user ID and service ID. When the admission control unit 332 receives a service provision request from a user with rank 0, the elapsed time from the time stored in the server storage unit 32 is within a predetermined period. The service providing unit 334 may be instructed to execute the process.

  7 to 9 are diagrams illustrating an example of an operation flow of the terminal processing unit 25. The operation flow described below is executed mainly by the terminal processing unit 25 in cooperation with each element of the mobile terminal 2 based on a program stored in the terminal storage unit 22 in advance.

  FIG. 7 is a diagram illustrating an example of an operation flow of the game progression unit 251. When the user instructs the terminal processing unit 25 to start a game via the operation unit 23, the terminal processing unit 25 starts processing based on the game program. Then, the game progress unit 251 displays the game progress screen 300 on the display unit 24 during the progress of the game (step S100). When any of the service selection buttons 304 included in the displayed game progress screen 300 is operated by the user via the operation unit 23 (Yes in step S101), the game progress unit 251 causes the entrance / exit processing unit 252 to The execution of entry / exit processing described later is instructed (step S102).

  Thereafter, the operation flow returns to step S100 again. On the other hand, when the service selection button 304 is not operated by the user (No in step S101), the game progression unit 251 performs a process of advancing the game (step S103). Then, the operation flow returns to step S100 again. In the operation flow of the game progression unit 251, the above process is repeated.

  FIG. 8 is a diagram illustrating an example of an operation flow of entrance / exit processing by the entrance / exit processing unit 252. First, the entrance / exit processing unit 252 transmits a service provision request including the user ID of the target user and the service ID of the target service to the server 3 (step S120).

  When a response indicating that the service can be provided is received from the server 3 (Yes in step S121), the entrance / exit processing unit 252 causes the service processing unit 253 to perform processing related to the service provided by the server 3. This is executed (step S122). Thereafter, when the “exit” button 428 is operated by the user on the service providing screen 420, the entrance / exit processing unit 252 transmits a service end request including the user ID of the user and the service ID of the target service to the server 3. (Step S123), and the process ends.

  On the other hand, when a response indicating that the service cannot be provided is received from the server 3 (No in step S121), the entrance / exit processing unit 252 receives the length of the standby queue for the service from the server 3. (Step S124). Then, the entrance / exit processing unit 252 displays the standby selection screen 320 on the display unit 24 (step S125). When the “not line up” button 328 is operated by the user on the standby selection screen 320 (No in step S126), the entrance / exit processing unit 252 cancels the service including the user ID of the user and the service ID of the target service. The request is transmitted to the server 3 (step S127), and the process is terminated.

  On the other hand, when the “line” button 326 is operated by the user on the standby selection screen 320 (Yes in step S126), the entrance / exit processing unit 252 displays the immediate entrance selection screen 340 on the display unit 24 (step S128). ). When the “acquire” button 346 is operated by the user on the immediate entrance selection screen 340 (Yes in step S129), the entrance / exit processing unit 252 immediately includes the user ID of the user and the service ID of the target service. An entrance request is transmitted to the server 3 (step S130). Thereafter, the operation flow proceeds to step S122.

  On the other hand, when the “do not acquire” button 348 is operated by the user on the immediate entrance selection screen 340 (No in step S129), the entrance / exit processing unit 252 displays the user ID of the user and the service ID of the target service. A waiting queue addition request including this is transmitted to the server 3 (step S131). Then, the entrance / exit processing unit 252 instructs the order waiting processing unit 254 to execute an order waiting process to be described later (step S132).

  Thereafter, when the user enters the “enter” button 416 on the order notification screen 410 displayed when the order in which the user receives the service comes (Yes in step S133), the operation flow is as follows. Proceed to step S122. On the other hand, when the “not enter” button 418 is operated by the user on the order notification screen 410 (No in step S133), the entrance / exit processing unit 252 ends the process.

  FIG. 9 is a diagram illustrating an example of an operation flow of order waiting processing by the order waiting processing unit 254. First, the order waiting processing unit 254 receives the number of users included in the waiting queue to which the target user is added (the length of the waiting queue) and the ranking of the users from the server 3 (step S140). Then, the order waiting processing unit 254 causes the display unit 24 to display the game progress screen 400 including information on the number of users and the ranking (Step S141). Thereafter, when a notification indicating that the target user has received the service provision order has been received from the server 3 (Yes in step S142), the order wait processing unit 254 displays the order notification screen 410. 24 (step S143), and the process is terminated.

  On the other hand, if the notification indicating that the target user has received the service provision order has not been received (No in step S142), the operation flow returns to step S140, and the above processing is repeated.

  10 to 12 are diagrams illustrating an example of an operation flow of the server processing unit 33. The operation flow described below is executed mainly by the server processing unit 33 in cooperation with each element of the server 3 based on a program stored in the server storage unit 32 in advance.

  FIG. 10 is a diagram illustrating an example of an operation flow of the server control unit 331. First, when receiving a service provision request from the mobile terminal 2 (Yes in Step S200), the server control unit 331 instructs the entrance control unit 332 to execute entrance control described later (Step S201). Thereafter, the operation flow returns to step S200. On the other hand, when the service provision request has not been received (No in step S200), the operation flow proceeds to step S202.

  When the server control unit 331 receives a service end request from the mobile terminal 2 (Yes in step S202), the server control unit 331 instructs the exit control unit 333 to execute exit control described later (step S203). Thereafter, the operation flow returns to step S200. On the other hand, when the service end request has not been received (No in step S202), the operation flow returns to step S200. In the operation flow of the server control unit 331, the above processing is repeated.

  FIG. 11 is a diagram illustrating an example of an operation flow of entrance control by the entrance control unit 332. First, the entrance control unit 332 determines whether or not the target user is a rank 0 user from the information included in the received service provision request (step S220). If the target user is ranked 0 (Yes in step S220), the operation flow proceeds to step S223 described later. On the other hand, when the target user is not in the rank 0 (No in step S220), the entrance control unit 332 refers to the service table, and for the target service, the maximum simultaneous provision number, the number of users who are providing the service, and the waiting queue Is acquired (step S221).

  If the number of users who are providing services is less than the maximum number of simultaneous offers (Yes in step S222), the entrance control unit 332 sets the user ID included in the received service provision request as a service providing user as a service table. (Step S223). Then, the entrance control unit 332 instructs the service providing unit 334 to provide the target service (step S224). Thereby, the entrance control part 332 complete | finishes a process.

  On the other hand, when the number of users who are providing services is equal to or greater than the maximum number of simultaneous offers (No in step S222), the admission control unit 332 acquires the user's mobile terminal 2 having the user ID included in the service provision request. The length of the waiting queue is transmitted (step S225). In response to this, when a service stop request is received from the mobile terminal 2 (step S226), the entrance control unit 332 ends the process. If an immediate entry request is received from the mobile terminal 2 (step S226), the operation flow proceeds to step S224. Further, when a waiting queue addition request is received from the portable terminal 2 (step S226), the entrance control unit 332 instructs the standby information management unit 335 to add the target user ID to the standby information table (step S226). S227).

  Subsequently, when the number of users included in the standby information is equal to or smaller than the upper limit threshold (No in step S228), the operation flow proceeds to step S232 described later. On the other hand, when the number of users included in the standby information exceeds the upper threshold (Yes in Step S228), the entrance control unit 332 causes the maximum number setting unit 336 to increase the maximum number of simultaneous provisions (Step S229). At this time, the entrance control unit 332 instructs the standby information management unit 335 to delete the user ID of the user with the lower rank for the target service from the standby information table (step S230). Then, the entrance control unit 332 causes the standby information management unit 335 to update the rank of each user ID included in the standby information table for the target service (step S231), and causes the user's portable terminal 2 corresponding to each user ID to The number of users in the current waiting queue and the new rank are transmitted (step S232). Thereby, the entrance control part 332 complete | finishes a process.

  FIG. 12 is a diagram illustrating an example of an operation flow of exit control by the exit control unit 333. First, the exit control unit 333 deletes the same user ID included in the service provision request from the “user ID during service provision” stored in the service table for the target service (step S240). At this time, the exit control unit 333 acquires, from the service table, the length of the queue for the target service, the number of users who are providing the service, and the maximum number of simultaneous offers (step S241). When the length of the waiting queue is 0 or the number of users who are providing services is equal to or greater than the maximum number of simultaneous provisions (No in step S242), the exit control unit 333 ends the process.

  On the other hand, if the length of the waiting queue is not 0 and the number of users who are providing services is less than the maximum number of simultaneous offers (Yes in step S242), the exit control unit 333 instructs the standby information management unit 335. Then, the user ID of the user with the lower rank for the target service is deleted from the standby information table (step S243). Then, the exit control unit 333 causes the standby information management unit 335 to update the order of each user ID included in the standby information table for the target service (step S244), and causes the mobile terminal 2 of the user corresponding to each user ID to The number of users in the current queue and the new rank are transmitted (step S245).

  When the number of users included in the standby information is less than the lower threshold (Yes in Step S246), the exit control unit 333 causes the maximum number setting unit 336 to decrease the maximum number of simultaneous provisions (Step S247). . Thereby, the exit control part 333 complete | finishes a process.

  As described above, the server 3 of the game system 1 has deliberately limited the maximum number of simultaneous provisions within the range of its processing capability, and has received a service provision request from the mobile terminals 2 having the number of users exceeding the maximum number of simultaneous provisions. In this case, the user information of the corresponding user is added to the standby information. In addition, when the number of users included in the standby information exceeds the upper limit threshold, the server 3 increases the maximum simultaneous provision number so that the number of users waiting for service provision does not exceed a certain number. In this way, the server 3 can control the length of the user's standby queue for the service to be provided within a certain range by changing the maximum number of simultaneous provisions.

  In addition, each function of the entrance / exit processing unit 252, the service processing unit 253, and the turn waiting processing unit 254 included in the terminal processing unit 25 may be realized by the server processing unit 33.

  The computer program for realizing each function provided in the server processing unit 33 can be provided in a form recorded on a computer-readable recording medium such as a semiconductor recording medium, a magnetic recording medium, or an optical recording medium. . The computer program can be installed in the server storage unit 32 from the recording medium using a known setup program or the like.

  It should be understood by those skilled in the art that various changes, substitutions and modifications can be made thereto without departing from the spirit and scope of the present invention.
