More specifically, the invention relates to a system and a method for efficiently transmitting data during a team game in a CPNS environment, which classify data that will be transmitted to a mobile communication terminal and an end-point terminal when a team game is executed between the mobile communication terminal and the end-point terminal through a wireless local area network to improve data transmission efficiency, and a CPNS server, a mobile communication terminal, and an end-point terminal for the same.
BACKGROUND ART
With the development of information communication technologies, a variety of end-point terminals capable of playing documents, images and videos, such as MP3 (Mpeg audio layer-3) player, PMP (Personal Multimedia Player), UMPC (Ultra Mobile Personal Computer), are used.
These end-point terminals download user's desired contents from personal computers and play the downloaded contents. However, it is impossible to download desired contents when a user is moving or the end-point terminal of the user cannot be linked to a PC.
To solve this problem, a technique of adding communication means connectable to a local area network, such as Bluetooth and UWB (UltraWideBand), to the end-point terminal was proposed.
According to this technique, it is possible to download contents from an external device through a local area network. However, this technique cannot download contents that are not stored in the external device even though the user wants the contents.
Furthermore, it is impossible to directly receive contents or services that were provided to mobile communication terminals from service providers or mobile telecommunication companies using the existing cellular communication even though a wireless local area network is used.

BEST MODE
A CPNS (Converged Personal Network Service) environment disclosed in the present invention allows a mobile terminal that can perform only near field communication and cannot use cellular communication through a mobile communication network to carry out near field communication with a mobile communication terminal functioning as a PN (Personal Network service) gateway to use a data service that can be provided through the cellular communication. In the present invention, an end-point terminal capable of performing near field communication can use a mobile game service through near field communication with a mobile communication terminal in the CPNS environment.
Preferred embodiments of the present invention will now be explained in detail with reference to the attached drawings.
FIG. 1 illustrates connections of a system according to the present invention and communication networks.
A system for efficiently transmitting data during a team game in a CPNS environment includes a CPNS server 100 which stores and manages information about an end-point terminal 300 and a mobile communication terminal 200, wherein the end-point terminal 300 communicates with the mobile communication terminal 200 through a wireless local area network and the mobile communication terminal 200 executes the team game through the wireless local area network, and classifies and processes data to transmit only the required game-related data to the mobile communication terminal 200 and the end-point terminal 300 respectively, the mobile communication terminal 200 extracting the data allocated thereto from the game-related data transmitted from the CPNS server 100 while executing the team game with the end-point terminal 300 through the wireless local area network and transmitting the data (shown in FIG. 3) destined for the end-point terminal 300 to the end-point terminal 300, and the end-point terminal 300 executing the game-related data transmitted from the mobile communication terminal 200, and when transmitting the game-related data to the CPNS server 100, classifying and processing the data, and then transmitting the data to the mobile communication terminal 200.
Here, the CPNS server 100 classifies the data into data (Data A shown in FIG. 2) required for both the mobile communication terminal and the end-point terminal, data (Data B shown in FIG. 2) required to be transmitted to only the mobile communication terminal, and data (Data C shown in FIG. 2) required to be transmitted to only the end-point terminal, as shown in FIG. 2.
Furthermore, the CPNS server 100 requests a contents providing server (not shown) to provide contents matched to specifications (for example, specification information including LCD size and Codec information, capabilities, etc.) of the mobile communication terminal and the end-point terminal with reference to the specifications and receives the contents. Here, the contents providing server may change the original of the contents according to the specifications of the mobile communication terminal. If the contents providing server transmits the original contents to the CPNS server 100, the CPNS server 100 changes the original contents to suit the specifications of the mobile communication terminal and the end-point terminal.
The mobile communication terminal 200 merges data, which will be transmitted from the mobile communication terminal 200 to the CPNS server, with the game-related data transmitted from the end-point terminal, indicates the source of the data, as shown in FIG. 4, and then transmits the data to the CPNS server 100.
The end-point terminal 300 classifies the game-related data into data allocated thereto and data commonly allocated to the end-point terminal and the mobile communication terminal when transmitting the game-related data to the CPNS server 100.
The end-point terminal 300 shown in FIG. 1 is a mobile terminal having a near field communication function, such as PMP, MP3 players, automobile navigation terminals, cellular phones, video game consoles, etc.
The wireless local area network can includes any communication network available for near field communication, such as wireless LAN, Bluetooth, UWB, WPAN (wireless Personal Area Networks), etc.
In FIGS. 2, 3 and 4, Data A represents information required for both the mobile communication terminal and the end-point terminal, Data B represents information required to be transmitted to only the mobile communication terminal and Data C represents information required to be transmitted to only the end-point terminal.
The CPNS server 100, the mobile communication terminal 200 and the end-point terminal 300 shown in FIG. 1 go through an initialization process for the CPNS service, which will now be described.
FIG. 5 is a flowchart illustrating an initialization method for the CPNS service according to the present invention.
Referring to FIG. 5, the end-point terminal 300 finds a mobile communication terminal that will function as a PN gateway device to use the CPNS service in step S10.
Then, the end-point terminal 300 requests the mobile communication terminal 200, found in step S10, to provide the CPNS service in step S20. In this step, the end-point terminal transmits information representing that the end-point terminal is available for the CPNS service to the mobile communication terminal.
The mobile communication terminal 200 checks whether the end-point terminal is available for the CNPS service when receiving the request for the CPNS service from the end-point terminal in step S30.
If the mobile communication terminal determines that the end-point terminal is available for the CPNS service in step S30, the mobile communication terminal 200 transmits an acknowledgement message representing that the CPNS service can be provided to the end-point detector 300 in step S40.
The end-point terminal 300 transmits the ID to the mobile communication terminal when receiving the acknowledgement message from the mobile communication terminal in step S50.
The mobile communication terminal 200 checks whether the format of the ID transmitted from the end-point terminal 300 corresponds to an ID format issued by CPNS, and when the formats correspond to each other, transmits an acknowledgement message representing that the CPMS service can be provided to the end-point terminal 300 in steps S60 and S70.
Then, the mobile communication terminal 200 transmits authentication information and IDs of the mobile communication terminal 200 and the end-point terminal 300 to the CPNS server 100 in step S80.
The CPNS server 100 checks the authentication information and IDs transmitted from the mobile communication terminal to determine whether the mobile communication terminal and the end-point terminal are available for the CPNS service in step S90.
If both the mobile communication terminal and the end-point terminal are available for the CPNS service, the CPNS server 100 notifies the end-point terminal that both the two terminals are available for the CPNS service to allow the end-point terminal to use the CPNS service including requesting for contents in step S100.
If any one of the mobile communication terminal and the end-point terminal is not available for the CPNS service, the CPNS server 100 notifies the end-point terminal of this fact and ends the service.
If the end-point terminal is not available for the CPNS service in step S30, the mobile communication terminal 200 transmits a message representing that the CPNS service cannot be provided to the end-point terminal 300, and then finishes the service.
If the format of the ID of the end-point terminal is not matched to the ID format issued by the CPNS in step S60, the mobile communication terminal 200 transmits a message representing that the CPNS service cannot be provided to the end-point terminal 300, and then ends the service.
The CPNS server 100 stores terminal information including specifications (for example, LCD size, Codec information, etc.) of the end-point terminal 300 provided with the CPNS service through near field communication with the mobile communication terminal 200 and terminal information about the mobile communication terminal 200 and refers to the stored information when providing the CPNS service.
