As shown in FIG. 6, a game supply method using a personal area network according to the present embodiment (for convenience of description, hereinafter, the term game provision method using a personal area network is referred to briefly as a game supply method unless a particular description is made) includes a creation step S100, an authentication step S200, an execution step S300 and a transmission step S400.
The creation step S100 is the step at which the first mobile communication terminal creates a game room, and the first end terminal, the second mobile communication terminal and the second end terminal request access to the created game room from the first mobile communication terminal. With reference to FIG. 7, the creation step S100 will be described. At a first creation step S110, the first mobile communication terminal creates a game room.
At a second creation step S120, the first end terminal, the first mobile communication terminal and the second end terminal search for a created game room.
At a third creation step S130, the first end terminal, the first mobile communication terminal and the second end terminal transmit a game room access request signal to the first mobile communication terminal.
The authentication step S200 is the step at which the service server performs authentication for the provision of service on the first end terminal, the first mobile communication terminal, the second end terminal and the second mobile communication terminal. With reference to FIG. 8, the authentication step S200 will be described. At a first authentication step S210, the first mobile communication terminal examines whether the first end terminal, the second mobile communication terminal and the second end terminal are serviceable devices. At this time, examination items may be the specifications of respective hardware devices, information about whether the service server has registered authenticated devices, etc.
At a second authentication step S220, when the first end terminal, the second mobile communication terminal and the second end terminal are determined to be serviceable devices at the first authentication step, they transmit their unique ID information to the first mobile communication terminal.
At a third authentication step S230, the first mobile communication terminal determines whether the unique ID information of the first end terminal, the second mobile communication terminal, and the second end terminal is normal information. The determination of whether the unique ID information is normal information is made by examining whether the unique ID information conforms to the format of unique ID information designated by the service server.
At a fourth authentication step S240, if it is determined at the third authentication step that the unique ID information is normal information, the first mobile communication terminal transmits the unique ID information of the first mobile communication terminal, the first end terminal, the second mobile communication terminal and the second end terminal to the service server.
At a fifth authentication step S250, the service server determines whether the first mobile communication terminal, the first end terminal, the second mobile communication terminal and the second end terminal are in a serviceable state on the basis of the unique ID information and subscription information of each mobile communication terminal and each end terminal. The term “serviceable state” means the state in which the mobile communication terminals normally operate, and in which the hardware specifications of the devices have no problems with the performance of a service. Here, the hardware specifications of devices are preferably stored in the storage unit of the service server. Meanwhile, the above-described subscription information is required to determine whether relevant terminals are clients subscribing to a rate system available for the use of a service.
At a sixth authentication step S260, if it is determined at the fifth authentication step that the terminals are in the serviceable state, an authentication message is transmitted to the first mobile communication terminal, the first end terminal, the second mobile communication terminal and the second end terminal.
The execution step S300 is the step at which the first end terminal, the first mobile communication terminal, the second end terminal and the second mobile communication terminal execute game data received from the service server. With reference to FIG. 9, the execution step S300 is described in detail. At a first execution step S310, the first mobile communication terminal receives game data from the service server and transfers the game data to the first end terminal, and the second mobile communication terminal receives game data from the service server and transfers the game data to the first end terminal. When the game data has been transmitted, the service server notifies the billing server of the transmission of the game data. Accordingly, the billing server additionally stores billing information generated for one or more of the first end terminal, the first mobile communication terminal, the second end terminal and the second mobile communication terminal.
At a second execution step S320, the first end terminal converts game data, generated during the execution of a game, into data recognizable by the first mobile communication terminal, and transfers the converted data to the first mobile communication terminal, and the second end terminal converts game data, generated during the execution of a game into data recognizable by the first mobile communication terminal and transfers the converted data to the first mobile communication terminal. Because of this step, the compatibility of data between the mobile communication terminal and the end terminal, which are not homogenous terminals, is possible. In this regard, it should be noted that the conversion of data may be performed by the service server rather than the end terminal or the mobile communication terminal. For this operation, the service server, for example, may collect all of the data, convert the data, and subsequently retransmit the converted data to respective end terminals and mobile communication terminals.
At a third execution step S330, the first mobile communication terminal transmits both game data, generated during the execution of a game, and the game data, received from the first end terminal, to the service server, and the second communication terminal transmits game data, generated during the execution of a game, and the game data, received from the second end terminal, to the service server.
At a fourth execution step S340, the service server converts the game data received from the first mobile communication terminal into data recognizable by the second mobile communication terminal, transmits the converted data to the second mobile communication terminal, converts the game data received from the second mobile communication terminal into data recognizable by the first mobile communication terminal, and transmits the converted data to the first mobile communication terminal. Through this step, the compatibility of data between the first and second mobile communication terminals, which are not homogenous terminals, is possible.
At a fifth execution step S350, the first mobile communication terminal converts the data received from the service server into data recognizable by the first end terminal and transmits the converted data, and the second mobile communication terminal-converts the data received from the service server into data recognizable by the second end terminal and transmits the data.
At a sixth execution step S360, the first mobile communication terminal, the first end terminal, the second mobile communication terminal and the second end terminal update a game screen on the basis of the received game data.
The transmission step S400 is the step at which the first end terminal, the first mobile communication terminal, the second end terminal and the second mobile communication terminal request game items from the service server, and the service server provides the game items. With reference to FIG. 10, the transmission step S400 will be described in detail. At a first transmission step S410, the first mobile communication terminal transfers both an item purchase request made by the first end terminal to the first mobile communication terminal, and an item purchase request generated by the first mobile communication terminal, to the service server, and the second mobile communication terminal transfers both an item purchase request made by the second end terminal to the second mobile communication terminal, and an item purchase request generated by the second mobile communication terminal, to the service server at step S410.
At a second transmission step S420, the service server notifies the game server of the item requests, the game server transmits the requested items to the service server, and the service server transfers items to the first mobile communication terminal and the second mobile communication terminal. At this time, it should be noted that the billing server may perform billing attributable to the use of items.
At a third transmission step S430, the first mobile communication terminal, the first end terminal, the second mobile communication terminal and the second end terminal apply the received items to the game.
