1. Field of the Invention
Embodiments of the invention generally relate to a communication destination determination apparatus, a communication destination determination method, a communication destination determination program, and a game system.
2. Description of the Related Art
When playing a game in a user terminal, a user terminal generally reads in a game program by installing the game program into the user terminal beforehand or by connecting a storage medium into which a game program is stored to the user terminal, hereinafter referred to as installing and the like, performs computation processing, and changes a screen displayed based on computation results. In contrast, a game system is proposed whereby a game is played via a network such as the Internet or the like, without installation or the like of a game program into the user terminal. For example, the user terminal is connected to a game manager via a network such as the Internet, and instruction information input from a user is transmitted to the game manager. The game manager performs a prescribed computation processing in accordance with the instruction information transmitted from the user terminal, and streams to the user terminal a screen that reflects the results in real time, based on the computation results. This enables the display of a screen based on the same as the conventional computation results and the playing of the game by the user, without installation or the like of a game program because the processing performed by the user terminal is only input and output.
When the above-described game system provides a multi-play game to a plurality of users playing simultaneously, the user terminals used by a plurality of users that are associated by matching processing are connected to the same game manager. Unless highly accessible communication is available, which depend upon the communication distance and communication bandwidth and the like between each of the user terminals and the game manager, it is not easy for the user to have an enjoyable game experience. It would have been desirable to have the users experience as pleasant communication condition as possible.
In one embodiment, a communication destination determination apparatus may include, but is not limited to, an acquisitor and a communication destination determiner. The acquisitor may be configured to acquire measurement results of accessibility of communication between each of a plurality of user terminals associated with each other and each of a plurality of game managers configured to communicate with each of the plurality of user terminals. The communication destination determiner may be configured to determine, based on the measurement results acquired by the acquisitor, and among the plurality of game managers, a target game manager as a communication destination to which the plurality of user terminals are to communicate.

An embodiment of the present invention will be described below, with references made to the drawings.
The first embodiment of the present invention will be described.
The communication destination determiner 10 matches and associates a plurality of user terminals 20 simultaneously playing the same game and, of the plurality of game managers 30, determines which of the game managers 30 is the communication destination with which the plurality of associated user terminals 20 should communicate, based on the communication condition between the user terminal 20 and the game manager 30.
The user terminal 20 transmits to the communication destination determiner 10 a request for matching other users playing the same game. The communication destination determiner 10 performs user matching to associate a plurality of user terminals 20 playing the same game, and determines from among the plurality of game managers 30 the game manager 30 that is the communication destination. The user terminal 20, via the network 5, connects to and communicates with the game manager 30 that has been determined by the communication destination determiner 10 to be the communication destination.
The game manager 30 communicates in accordance with the connection from the user terminal 20 and provides a multi-play game service that can be played via the network 5.
In this manner, in the present embodiment, game managers 30 providing a multi-play game via the network 5 are installed in a distributed manner at a plurality of locations. Of the plurality of game managers 30, the game manager 30 at a location enabling the most accessible communication for the matched user terminals 20 is determined and that game manager 30 is caused to provide the game service. This enables a more pleasant communication environment in a game played by a user than in the case of a game manager 30 installed in one location. The locations, number, and scale of the game managers 30 such as this can be established in accordance with the number of users to be connected to the game system 1, the type of games, and the like.
Referring again to
The communication destination determiner 10 has a communicator 11, a storage 12, and a controller 14.
The communicator 11 communicates with another computer via the network 5.
The storage 12 is configured using storage medium such as a RAM (random-access memory), a ROM (read-only memory), or a HD (hard-disk) drive or the like, or a combination thereof, and stores various information referenced by the communication destination determiner 10 when it operates. The storage 12 has a measurement results storage 13.
The measurement results storage 13 stores the results of measuring the accessibility of communication between a plurality of user terminals 20 associated by matching and the plurality of game managers 30 that can communicate with the plurality of user terminals 20. The accessibility of communication is a value that represents the speed and degree of communication performed by a user terminal 20 and a game manager 30. The greater is the accessibility of communication, the faster and more accessible is the communication, and the smaller is the accessibility of communication, the slower and less accessible is the communication.
The accessibility of communication can be, for example, a period of time from transmission by the user terminal 20 of a prescribed packet amount to the game manager 30 until it receives a response. The period of time is, for example, the amount of time (RTT: roundtrip time) from the transmitting of an echo request packet based on the ICMP to the game manager 30 by the user terminal 20 executing a ping program until the receiving of an echo reply packet from the game manager 30 in response thereto. In this case, the smaller is the value of the period of time, the greater is the accessibility of communication, and the larger is the value of the period of time, the smaller is the accessibility of communication.
Referring again to
The matching processor 15, in response to a matching request transmitted from the user terminal 20, performs matching that determines combinations of user terminals 20 playing the same game. This associates a plurality of user terminals 20.
The acquisitor 16 acquires the results of measuring the accessibility of communication between the plurality of user terminals 20 associated by the matching processor 15 and the plurality of game managers 30 that can communicate with each of the plurality of user terminals 20. For example, the acquisitor 16 transmits an accessibility of communication measurement request to a plurality of user terminals 20 associated by the matching processor 15, receives measurement results from the user terminals 20 in response to the transmitted measurement request, and stores the received measurement results in the measurement results storage 13. In this case, for example, the acquisitor 16 includes a list of IP addresses of a plurality of game managers 30 within the measurement request to be transmitted to the user terminals 20, and the user terminals 20 measure the communication accessibility with respect to each of the IP addresses indicated in the list included in the measurement request.
The communication destination determiner 17, based on the measurement results acquired by the acquisitor 16, determines from the plurality of game managers 30 the game manager 30 that is the communication destination of the associated plurality of user terminals 20. The communication destination determiner 17, based on the results of measuring, for each game manager 30, the accessibility of communication between that game manager 30 and the plurality of mutually associated user terminals 20, calculates a determination reference value corresponding to each of the plurality of game managers. The determination reference values are referenced and, from among the plurality of game managers 30, a game manager is determined to be the one with which the plurality of user terminals should communicate. For example, the communication destination determiner 17, for each of the plurality of game managers 30, calculates the sum of the measurement results between that game manager 30 and the plurality of associated user terminals 20 and, based on the results of comparing the calculated sums, determines the game manager 30 with which the plurality of associated user terminals 20 should communicate.
For example, the communication destination determiner 17 reads out the period of times acquired by the acquisitor 16 and stored in the measurement results storage 13 and, for each of the plurality of game managers 30, calculates the sum of the period of times between that game manager 30 and the plurality of user terminals 20. The communication destination determiner 17 determines as the game manager 30 that is the communication destination, with which the plurality of user terminals 20 should communicate the game manager 30 having the smallest calculated sum. In the example of
A user terminal 20 is a computer used by a user, such as a PC (personal computer), a tablet PC, a smartphone, or a game machine or the like. In the present embodiment, the description is for a PC used as the user terminal 20. The user terminal 20 has an input device such as a keyboard, a mouse, or a touch panel or the like, and accepts input of instruction information from a user. The user terminal 20 may have a display that displays information such as text and images and a speaker or the like that outputs sound. The user terminal 20 has a communicator 21a storage 22, and a controller 23.
In this case, the user terminal 20 uses a game service provided by the game manager 30 connected via the network 5 and allows a user to play a game. In the present embodiment, the user terminal 20 first transmits a matching request to the communication destination determiner 10 based on instruction information input from a user. The user terminal 20 also measures and transmits to the communication destination determiner 10 the communication accessibility between it and a plurality of game managers 30 connected via the network 5. Of the plurality of game managers 30, connection is made to the game manager 30 determined by the communication destination determiner 10 to be the communication destination. When a game is started by the connected game manager 30, the user terminal 20 transmits instruction information to the game manager 30, receives from the game manager 30 a streamed screen reflecting the result of prescribed computation processing by the game manager 30 in accordance with transmitted instruction information, which screen it presents on a display. The instruction information transmitted to the game manager 30 by the user terminal 20 is, for example, information indicating operations in a game. This enables the user to play the game without installation or the like of a game program into the user terminal 20.
The communicator 21 communicates with the game manager 30 via the network 5.
The storage 22 stores various information referenced by the user terminal 20 when it operates. The storage 22 is configured by using a storage medium such as RAM, ROM, a HD drive or the like, or using a combination thereof.
The controller 23 is configured by, for example, a CPU, and controls various parts of the communication destination determiner 10. The controller 23 has a measurer 24.
The measurer 24 measures the communication accessibility between its own user terminal 20 and each of a plurality of game managers 30 connected via the network 5. For example, the measurer 24, by the above-described ping program, measures the required times for communication with each of a plurality of game managers 30, and then transmits the measurement results to the communication destination determiner 10 via the communicator 21.
The game manager 30 is a computer providing a user terminal 20 with a game service allowing the user terminal 20 to play a game via the network and has a communication controller 31 and a game controller 32.
The communication controller 31 is configured by, for example, a CPU, and controls communication between the game manager 30 and other computers. For example, the communication controller 31 receives a packet transmitted from a user terminal 20 by a ping program and transmits a response to the received packet. The communication controller 31 also, when it is determined by the communication destination determiner 10 as communication destination of the plurality of associated user terminals 20, causes the game controller 32 to execute game processing. The communication controller 31 buffers a movie generated by game controller 32 in response to each of a plurality of user terminals 20, performing encoding at a bit rate suitable for real-time movie streaming, and transmits the movie to the user terminal 20 in streaming format. Streaming is the successive transfer and playback of time sequence movie data as the data is being received. This enables a real-time display on the user terminal 20 of a movie that changes in accordance with instruction information.
The game controller 32 executes a game program performing computation of a game for an associated user terminal 20. The game program, based on instruction information transmitted by each of a plurality of associated user terminals 20, performs prescribed computation processing and generates a movie based on the calculation results thereof. The game provided by the game controller 32 is, for example, a sports game such a race game, an action game such as a fighting game, a shooting game such as FPS (First Person Shooter), a role-playing game, a puzzle game, or a simulation game, and is a multi-play game in which a plurality of user terminals 20 are allowed to play the same game simultaneously. The game controller 32 uses a GPU (graphic processing unit) of the game manager 30 to render the game screen and output to the communication controller 31a movie, which is a continuity of screen frames that change with time.
Next, referring to the drawings, an example of the operation of the game system 1 according to the present embodiment will be described.
In this case, a matching request is made to the communication destination determiner 10 from the user terminal 20-1, the user terminal 20-2, the user terminal 20-3, and the user terminal 20-4, and the communication destination determiner 10 matches and associates the user terminals 20. The acquisitor 16 of the communication destination determiner 10 transmits a communication accessibility measurement request to the user terminal 20-1, the user terminal 20-2, the user terminal 20-3, and the user terminal 20-4 (step S1).
When the user terminal 20-1 receives the communication accessibility measurement request from the communication destination determiner 10, the measurer 24-1 thereof measures the communication accessibility with the game manager 30-1, the game manager 30-2, the game manager 30-3, the game manager 30-4, and the game manager 30-5 (step S2). The user terminal 20-1 transmits the communication accessibility measurement results to the communication destination determiner 10 (step S3). Upon receiving the measurement results transmitted from the user terminal 20-1, the acquisitor 16 of the communication destination determiner 10 stores the received measurement results into the measurement results storage 13.
In the same manner, when the user terminal 20-2 receives the communication accessibility measurement request from the communication destination determiner 10, the measurer 24-2 thereof measures the communication accessibility with the game manager 30-1, the game manager 30-2, the game manager 30-3, the game manager 30-4, and the game manager 30-5 (step S4). The user terminal 20-2 transmits the communication accessibility measurement results to the communication destination determiner 10 (step S5). Upon receiving the measurement results from the user terminal 20-2, the acquisitor 16 of the communication destination determiner 10 stores the received measurement results into the measurement results storage 13.
In the same manner, when the user terminal 20-3 receives the communication accessibility measurement request from the communication destination determiner 10, the measurer 24-3 thereof measures the communication accessibility with the game manager 30-1, the game manager 30-2, the game manager 30-3, the game manager 30-4, and the game manager 30-5 (step S6). The user terminal 20-3 transmits the communication accessibility measurement results to the communication destination determiner 10 (step S7). Upon receiving the measurement results from the user terminal 20-3, the acquisitor 16 of the communication destination determiner 10 stores the received measurement results into the measurement results storage 13.
In the same manner, when the user terminal 20-4 receives the communication accessibility measurement request from the communication destination determiner 10, the measurer 24-4 thereof measures the communication accessibility with the game manager 30-1, the game manager 30-2, the game manager 30-3, the game manager 30-4, and the game manager 30-5 (step S8). The user terminal 20-4 transmits the communication accessibility measurement results to the communication destination determiner 10 (step S9). Upon receiving the measurement results from the user terminal 20-4, the acquisitor 16 of the communication destination determiner 10 stores the received measurement results into the measurement results storage 13.
The communication destination determiner 17 of the communication destination determiner 10, based on the measurement results of each user terminal 20 stored in the measurement results storage 13, determines the game manager 30 that is the communication destination with which the user terminals 20 should communicate (step S10). In the present embodiment, this determination is made, as described above, by the communication destination determiner 17 referencing the measurement results storage 13 and calculating the sum of the communication accessibility measured at each of the user terminals 20 for each of the game managers 30, and taking the game manager 30 having the smallest sum to be the communication destination with which each user terminals 20 are to communicate. In this case, the game manager 30-1 is determined to be the communication destination. The communication destination determiner 17 transmits, via the communicator 11, identification information indicating the determined communication destination to the user terminal 20-1, the user terminal 20-2, the user terminal 20-3, and the user terminal 20-4 (step S11). The identification information indicating the communication destination is, for example, the IP address or port number or the like of the game manager 30. The user terminal 20-1, the user terminal 20-2, the user terminal 20-3, and the user terminal 20-4 connect to and communicate with the game manager 30-1 indicated by the identification information transmitted from the communication destination determiner 10 (step S12) and begin a multi-game game.
Although the above has been a description, referring
As described above, according to the present embodiment, game managers 30 are installed in a plurality of locations and, based on the communication accessibility of each of a plurality of associated user terminals 20, the plurality of user terminals 20 are made to communicate with the game manager 30 of the plurality of game managers 30 with which the communication accessibility is greatest. This enables selection of a game manager 30 with which highly accessible communication is possible, compared to the case in which a game manager 30 is installed in only one location and there is no opportunity for selection by the user terminals 20, thereby communicating with one game manager 30 to play a game. This enables associated user terminals 20 to play the game smoothly.
A second embodiment of the present invention will be described. Although, the game system 1 in the present embodiment has a similar configuration as the game system 1 in the first embodiment, the method of determination of the communication destination by the communication destination determiner 17 of the communication destination determiner 10 is different.
In the first embodiment, the communication destination determiner 17, for each of a plurality of game managers 30, calculates the sum of the measurement results between that game manager 30 and a plurality of associated user terminals 20 and, based on the results of comparing the calculated sums, determines the game manager 30 with which the plurality of associated user terminals 20 should communicate. In this case, for example as shown in
Although this enables a determination of a game manager 30 capable of communicating at higher accessibility with a relatively large number of user terminals 20, compared with other game managers 30, whereas the required time for the user terminal 20-1, the user terminal 20-2, and the user terminal 20-4 is 10, the required time for the user terminal 20-3 is 80. In this case, a variation occurs between the user terminals 20 in the time from the input of instruction information to the user terminal 20 until the computation results are displayed. Given this, particularly in a game in which the game progress is influenced by the timing of input of instruction information from a user terminal 20 or by real-time performance, there could be cases in which smooth progress through the game is not possible.
For example, in response to the action of a character corresponding to the user terminal 20-1, which has a small required time, when causing action of a character corresponding to the user terminal 20-3, which has a large required time, because of the relative delay of the action of the character corresponding to the user terminal 20-3, the user of the user terminal 20-3 might sense an unfairness. Also, in a scene in which a prescribed effect is to be obtained by a plurality of user terminals 20 inputting prescribed instruction information simultaneously, it might be difficult to adjust the timing of inputs of the prescribed instruction information from a plurality of user terminals 20 so as to be simultaneous. In such cases, of the plurality of user terminals 20, it is desirable that a determination be made of a game manager 30 for which there does not exist a user terminal 20 having a particularly small communication accessibility.
Given this, the communication destination determiner 17 of the present embodiment calculates a weighted sum of the measurement results for each of a plurality of game managers 30 with each of a plurality of user terminals 20 and, based on the results of comparing the calculated sums, determines the game manager 30 with which the plurality of user terminals 20 should communicate. Specifically, for example, the communication destination determiner 17, for each of a plurality of game managers 30, calculates the sum of the squared values of the required time for each of the plurality of user terminals 20 with respect to that game manager 30, and determines the game manager 30 having the smallest calculated sum as the game manager 30 with which the plurality of user terminals 20 should communicate.
If this is done, in the example shown in
In addition to this method of determining the communication destination, it is also possible, for example, to determine as the communication destination the game manager 30 that has the smallest maximum value of required time with respect a plurality of user terminals 20 for that game manager 30. Alternatively, the game manager 30 having the smallest variation in required time can be determined to be the communication destination. For example, by determining, in accordance with the frame rate of the game results movie, the game manager 30 that makes the difference in frame rates among the user terminals 20 as possible small as the communication destination, it is possible to have a plurality of users play a game with the greatest possible fairness. Alternatively, the communication destination can be determined based on the required time with the maximum frequency of occurrence, or the communication destination can be determined based on the standard deviation of the required time. Alternatively, the communication destination can be determined based on a combination of such calculation results.
The third embodiment of the present invention will be described. Although the first embodiment has been described with the game manager 30 of a single computer, a game manager 30 can be configured by a plurality of computers in the game system 1 in which many user terminals 20 are connected.
Because the plurality of game managers 130 has a similar configuration, they will be described as the game manager 130, omitting the suffixes -1, -2, and the like when not particularly distinguishing therebetween. The game manager 130 is a computer group providing a game service allowing a user terminal 20 to play a game via the network 5, and has a communication controller 131 and a plurality of game servers 132 (game server 132a, game server 132b, . . . ). In this case, because the game servers 132 have a similar configuration, they will be described as the game server 132, omitting the suffixes a, b, and the like, when not particularly distinguishing therebetween. Although two game servers 132 are shown in the drawing, an arbitrary number of game servers 132 may be provided in the game manager 130.
The communication controller 131 has a similar configuration as the communication controller 31 in the first embodiment.
The game server 132 has a function of virtualizing its own computer resources and launching and operating a virtual machine, on which a game program that performs computation processing for a game for a user terminal 20 is run. In this case, a game program for a plurality of associated user terminals 20 will cause progress through the multi-play game, with mutual communication within the game manager 30. The movie generated in the virtual machine on the game server 132 is distributed by streaming to the user terminals 20 by the communication controller 131.
Although, in the first to the third embodiments, the examples shown have been ones in which the required time measured base on a ping program was applied as the communication accessibility, with the communication accessibility being taken as greater, the smaller is the required time and lower, the larger is the required time, another value can be used as a measure of the speed and accessibility of communication between the user terminals 20 and the game manager 30. For example, the communication accessibility can be taken to be greater, the smaller is the packet loss rate in pinging, and smaller, the larger is the packet loss rate in pinging. Alternatively, for example, a large number of packets can be transmitted from the user terminal 20 to the game manager 30, and the transfer rate can be calculated based on the number of packets received by the game manager 30 per unit of time. In this case, the larger is the number of packets that could be transmitted in a unit of time, the greater is the communication accessibility, and the smaller is the number of packets that could be transmitted in a unit of time, the smaller is the communication accessibility. Alternatively, this type of transfer rate may be measured by a TTCP (test tcp) command, and an FTP (file transfer protocol) command can be used to transfer a file and the time required for transfer measured.
Although in the above-noted first to third embodiments the examples shown have been ones in which the acquisitor 16 transmits a communication accessibility measurement request to user terminals 20 associated by the matching processor 15, the communication accessibility can be measured beforehand by each user terminal 20 and, when a matching request is transmitted to the communication destination determiner 10, the results of the communication accessibility measurement can be transmitted simultaneously. Alternatively, the user terminals 20 can periodically measure the communication accessibility each prescribed time and transmit the measurement results to the communication destination determiner 10.
Also, in the configurations of the above-noted first to third embodiments, the various elements thereof can be distributed or concentrated in an arbitrary number of computers, in accordance with a cloud or network environment, the size in number of players, the types of games, the number of pieces of and specifications of hardware provided to configure the game system. For example, although in the above-noted first to the third embodiments the communication destination determiner 10 is configured to have a matching processor 15 performing matching processing, a matching server performing matching may be provided separately from the communication destination determiner 10.
Although in the above-noted first to third embodiments, the calculation of the determination reference value and the determination of the communication destination based on the above-described communication accessibility measurement results is performed by the communication destination determiner 10, this example of configuration is not a restriction and, for example, a configuration may be adopted wherein calculation of the determination reference value based on the communication result is done not by the communication destination determiner 10, but rather by the game manager 30 or another manager (not shown), and wherein the communication destination determiner 10 acquires the calculated determination reference value and determines the game manager 30 that is the communication destination.
A program for implementing the functionality of the processing units in the present embodiment may be stored in a computer-readable recording medium, a computer system being made to read out and execute the program stored in the recording medium, so as to perform the processing of the various units of the application system . The term “computer system” includes an operating system and hardware such as peripheral devices. The term “computer system” also includes a WWW system having a webpage-providing environment (or webpage-displaying environment). The term “computer-readable recording medium” refers to a removable medium such as a flexible disk, an optomagnetic disk, a ROM, a CD-ROM, or the like, or a storage device such as a hard disk drive or the like built into a computer system.
