       [0001]     This is a continuation of International Application No. PCT/CN2005/002226, which was filed on Dec. 16, 2005, and which, in turn, claimed the benefit of Chinese Patent Application No. 200410104104.3, which was filed on Dec. 29, 2004, the entire disclosures of which are hereby incorporated herein by reference. 
     
    
     BACKGROUND OF THE DISCLOSURE  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to the field of mobile online game services, and particularly, to a system of mobile online game and a method for communicating between mobile game terminals.  
         [0004]     2. Background of the Invention  
         [0005]     At present, a mobile online game system mainly includes a game platform and mobile game terminals. The game platform is used for providing users with a series of such services as game service release, parallel operation of multiple game services, discovery of the user of a game service, process control of game operation, charging of the user account. The mobile game terminal provides a game platform for users to access and an operating platform for users to play games.  
         [0006]     In the existing mobile online game system, the data interaction between a game platform and numerous mobile game terminals is implemented through a communication network which is huge. The mobile game terminal mainly includes a game application unit, which forwards the data generated by the game operation to a Mobile Game Platform (MGP) of the game platform for corresponding processing. The game platform primarily includes the MPG, which receives the data sent from a mobile game terminal through a communication network, and performs the corresponding processing according to the type of the data received by the MGP The data sent from the mobile game terminal to the MPG primarily include two parts; one part is core data for game logic processing, system management, billing, and etc, and the core data is the main part of the game platform service, and needs corresponding analysis or processing by the MGP; the other part is communication data between the mobile game terminals such as interaction data of voice or text etc, and the communication data is sent from an originating mobile game terminal and forwarded through the MGP to a destination mobile game terminal.  
         [0007]     The inventors found in the inventing processes that in the above processes, the MGP does not perform any processing to the communication data between the mobile game terminals, but only acts as a forwarder. Although the data forwarding is not the main service of the game platform, the system resource is limited after all, so along with the user group of game platform becoming huger and huger, even the service of just forwarding data through the game platform may consume considerable system resources, which lead to a heavy load of service processing for the game platform. Since the communication between the mobile terminals is performed by the data forwarding via the game platform, the interaction periods are prolonged, the communication rate is decreased, and the efficiency and effect of operation of the whole mobile online game system are affected.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0052]     This invention is hereinafter further described in details with reference to the accompanying drawings so as to further clarify the technical schemes.  
         [0053]     According to an embodiment of the present invention, a first mobile game terminal acquires the P2P communication address of a second mobile game terminal from a game platform, and creates a P2P connection with the second mobile game terminal according to the P2P communication address; the first mobile game terminal communicates with the second mobile game terminal via the P2P connection.  
         [0054]     In the following descriptions, the originating mobile game terminal is equivalent to the first mobile game terminal, and the destination mobile game terminal is equivalent to the second mobile game terminal.  
         [0055]     As shown in  FIG. 1 , which illustrates the structure of a mobile online game system; the system mainly includes a game platform and multiple mobile game terminals.  
         [0056]     Each mobile game terminal includes a game application unit and a P2P application unit. The game application unit is used for sending a P2P connection creating request to an MPG, upon receiving a response from the MPG, sending a P2P connection creating instruction to the P2P application unit; and after the P2P connection is created, determining whether the data generated by a game operation needs to be transmitted via the P2P connection, if the data needs to be transmitted, sending the data to the P2P application unit, otherwise, sending the data to the MPG; in addition, the game application unit is still used for receiving data from the other mobile game terminals sent by the P2P application unit of the other mobile game terminal. The P2P application unit, upon receiving the P2P connection creating instruction from the game application unit, creating a P2P connection with the destination mobile game terminal, and performing the data interaction with the other mobile game terminals via the P2P connection.  
         [0057]     The P2P connection creating request sent by the game application unit to the MPG includes identifier (ID) information of the destination mobile game terminal, and the response from the MPG to the originating mobile game terminal includes the communication address of the destination mobile game terminal. And the communication network protocol corresponding to the created P2P connection may be the Transmission Control Protocol/Internet Protocol (TCP/IP) etc, the corresponding P2P communication address of the mobile game terminal is based on the TCP/IP as well.  
         [0058]     The game platform includes an MPG, a database, and a P2P management unit. The MPG is used for receiving the P2P connection creating request sent by an originating mobile game terminal, and sending the P2P connection creating request to a P2P management unit, and receiving a response returned from the P2P management unit, then forwarding the response returned from the P2P management unit to the originating mobile game terminal. The database is used for storing P2P registration information of mobile game terminals. The P2P management unit is used for reading the P2P registration information of the destination mobile game terminal stored in the database according to identifier in the P2P connection creating request from the MPG, and sending the response from the P2P management unit to the MPG. The P2P registration information mainly includes the communication address of the destination mobile game terminal. The allocation of the communication address of the mobile game terminal i.e. the IP address, is controlled by the wireless network communication system, and the communication address of the mobile game terminal loading each time on the MPG platform may be different. Thus the information of the communication address of the mobile game terminal stored in the database is updated each time when the mobile game terminal loads on the game platform.  
         [0059]     A first optional proposal is that the P2P management unit may include a database query unit, which is used for, upon receiving the P2P connection creating request forwarded by the MPG, reading the P2P registration information of the destination mobile game terminal stored in the database, and returning to the MPG a response carrying the communication address of the destination mobile game terminal.

         [0060]     A second optional proposal is that the P2P management unit may include an authentication interface unit, which is used for, upon receiving the P2P connection creating request forwarded by the MPG, reading the P2P registration information of the destination mobile game terminal stored in the database, implementing authentication of the mobile game terminal, and when the authentication succeeds, returning to the MPG an authentication success response carrying the communication address of the destination mobile game terminal. In this proposal, the P2P registration information includes the communication address of the destination mobile game terminal, and authentication information such as the record information provided upon registering representing whether the destination mobile game terminal is willing to create a P2P connection with the originating mobile game terminal etc.  
         [0061]     A third optional proposal is that the P2P management unit may include both an authentication interface unit and a database query unit. The authentication interface unit, upon receiving the P2P connection creating request forwarded by the MPG, sends a query instruction to the database query unit, and receives the P2P registration information of the mobile game terminal returned by the database query unit, implements authentication of an originating mobile game terminal, and returns a response to the MPG. The database query unit, receives the query instruction from the authentication interface unit, reads the P2P registration information of the destination mobile game terminal stored in the database according to the query instruction, and sends the P2P registration information read from the database to the authentication interface unit. In this proposal, the P2P registration information includes the communication address of the destination mobile game terminal, and authentication information such as the record information provided upon registering representing whether the destination mobile game terminal is willing to create a P2P connection with the originating mobile game terminal etc.  
         [0062]     The structure of the mobile online game system is described hereinbefore according to an embodiment; and description of the method for communicating between the mobile game terminals will be given. The premise of the method in an embodiment of this invention is that: when the game service is running, a communication network port of the P2P application unit, such as TCP/IP port etc, is opened.

         [0089]     Process  501 : a game application unit of an originating mobile game terminal sends a P2P connection creating request to an MGP, and ID information of an originating mobile game terminal and a destination mobile game terminal is carried in the P2P connection creating request. The game application unit may send the P2P connection creating request to the MGP after receiving a P2P connection creating instruction from a user.  
         [0090]     Process  502 : the MGP, after receiving the P2P connection creating request, forwards the P2P connection creating request to an authentication interface unit of a P2P management unit.  
         [0091]     Process  503 : the authentication interface unit of the P2P management unit, after receiving the P2P connection creating request, sends a query instruction to a database query unit of the P2P management unit, and the ID information of the originating mobile game terminal and the destination mobile game terminal is contained in the query instruction.  
         [0092]     Process  504 : the database query unit, after receiving the query instruction, reads the P2P registration information stored in a database, and sends the P2P registration information read from the database to the authentication interface unit, the P2P registration information mainly includes right information of the originating mobile game terminal and right information of the destination mobile game terminal, and P2P communication address of the destination mobile game terminal.  
         [0093]     Process  505 : the authentication interface unit, after receiving the P2P registration information sent by the database query unit, determines whether the originating mobile game terminal has right to create a P2P connection with the destination mobile game terminal, if the originating mobile game terminal has the right, the process continues to Process  506 ; otherwise, the process jumps to Process  510 .  
         [0094]     The determining of whether the originating mobile game terminal has right to create the P2P connection with the destination mobile game terminal may include: determining whether the P2P registration information includes record information representing that the destination mobile game terminal is willing to create a P2P connection with the originating mobile game terminal, if the record information is included, determining that the originating mobile game terminal has right to create the P2P connection with the destination mobile game terminal; otherwise, determining that the originating mobile game terminal does not have the right.  
         [0095]     Process  506 : the authentication interface unit returns to the MGP an authentication success response, which includes the P2P communication address of the destination mobile game terminal, and the MGP forwards the authentication success response to the originating mobile game terminal.  
         [0096]     Process  507 : the game application unit of the originating mobile game terminal, after receiving the authentication success response, sends a P2P connection creating instruction to a P2P application unit, which includes the P2P communication address of the destination mobile game terminal.  
         [0097]     Process  508 : the P2P application unit, after receiving the P2P connection creating instruction sent by the game application unit, creates a P2P connection with the destination mobile game terminal according to the P2P communication address of the destination mobile game terminal contained in the P2P connection creating instruction.  
         [0098]     Process  509 : the originating mobile game terminal communicates with the destination mobile game terminal via the P2P connection, and the process ends.  
         [0099]     After the P2P connection is created, the game application unit determines whether the data generated by a game operation in the running of game needs to be transmitted via the P2P connection, if the data needs to be transmitted, sends the data to the P2P application unit which forwards the data to the destination mobile game terminal via the P2P connection; otherwise, sends the data to the MPG of the mobile game platform for corresponding processing. To determine whether the data generated by a game operation in the running of game needs to be transmitted to the destination mobile game terminal via the P2P connection is to determine whether the data generated by the game operation in the running of game is communication data, if the data is communication data, determines that the data needs to be transmitted via the P2P connection, otherwise, determines that the data is common game data. Alternatively, information representing the need of the transmission via the P2P connection may be carried by the communication data sent to the destination mobile game terminal, so that whether the data needs to be transmitted via a P2P connection may be determined by determining whether the data carries the information representing the need of the transmission via the P2P connection.  
         [0100]     Process  510 : the authentication interface unit returns to the MGP an authentication failure response for creating a P2P connection, and the MGP forwards the authentication failure response to the originating mobile game terminal, and the process ends.
