Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, FIG. 1 is a diagram showing a connection relationship between a system and a communication network according to the present invention.

As shown in the figure, a system for providing a large amount of content in a CPNS environment receives a content request through a mobile communication network from any one of a plurality of mobile communication terminals connected to a group to transmit and receive information through a local area wireless communication network. After requesting and receiving the corresponding content from the content providing server 500, the CPNS checks the transmission rate of the mobile communication terminals belonging to the group, and divides the data amount of the content according to each transmission rate and transmits the content to the mobile communication terminal. Information is transmitted and received between the server 100 and mobile communication terminals set in the same group through the local area network, and the content is divided from the CPNS server 100 in proportion to respective transmission rates as the content is requested to the CPNS server 100. After each reception, the content is transmitted and received between mobile communication terminals through short-range wireless communication. It includes a plurality of mobile communication terminal (200, 300a ~ 300c) to process the merge.

If the master mobile communication terminal 200 requesting content to the CPNS server 100 among the plurality of mobile communication terminals uses the content, the master mobile communication terminal 200 except for the other mobile communication terminals 300a to 300c It provides its own billing-related information and content user information, and the CPNS server 100 performs the billing process so that all the charges for content provision is charged to the master mobile communication terminal (100).

On the other hand, when the plurality of mobile communication terminals all use the content transmitted from the CPNS server 100, the master mobile communication terminal 200 of the plurality of mobile communication terminals are all the plurality of mobile communication terminals (200a ~ 200c) The fact that the information is used is transmitted to the CPNS server 100, and the CPNS server 100 processes the charging for providing the content to be charged to all of the plurality of mobile communication terminals.

First, in order to use the CPNS service, the slave mobile communication terminal 300 searches for a mobile communication terminal to perform the role of a Personal Network (PN) Gateway Device (S10).

Subsequently, the slave mobile communication terminal 300 requests a service from the master mobile communication terminal 200 found in step S10. Here, the slave mobile communication terminal 300 also transmits CPNS capable information (S20).

Subsequently, when the master mobile communication terminal 200 receives the service request transmitted to the slave mobile communication terminal 300, the master mobile communication terminal 200 checks whether the CPNS service is available in the slave mobile communication terminal 300 (S30).

As a result of checking in step S30, when the CPNS service of the slave mobile communication terminal 300 is available, the master mobile communication terminal 200 transmits an authentication message indicating that the CPNS service is available to the slave mobile communication terminal 300 (S40).

When the slave mobile communication terminal 300 receives an authentication message indicating that CPNS service is available from the master mobile communication terminal, it transmits its ID (S50).

The master mobile communication terminal 200 checks whether the format of the ID transmitted from the slave mobile communication terminal 300 matches the ID format issued by CPNS, and if the format matches, the slave mobile communication terminal ( In step 300, an authentication message indicating that service is available is transmitted (S60 and S70).

Thereafter, the master mobile communication terminal 200 transmits authentication information and IDs of itself and the slave mobile communication terminal 300 to the CPNS server 100 (S80).

The CPNS server 100 checks the authentication information and the ID transmitted from the master mobile communication terminal, and determines whether the CPNS service is available (S90).

If the service is available to both the master mobile terminal and the slave mobile communication terminal, the CPNS server 100 notifies the slave mobile communication terminal 300 so as to perform a CPNS service including a content request thereafter (S100).

If any of the master mobile terminal and the slave mobile communication terminal is unavailable, the CPNS server 100 notifies the slave mobile communication terminal 300 and terminates the service.

On the other hand, if the CPNS service of the slave mobile communication terminal 300, as a result of the check in step S30, the master mobile communication terminal 200 transmits a message that the service is not available to the slave mobile communication terminal 300, and then service Quit.

On the other hand, if the ID format of the slave mobile communication terminal 300 does not match, as a result of checking in step S60, the master mobile communication terminal 200 transmits a message indicating that the service is not available to the end terminal, and then performs a service. Quit.

Here, the content requesting and receiving unit 130 refers to the specifications of the mobile communication terminals 200, 300a to 300c stored in the database 180, requests a content corresponding to the specification to the content providing server, and then receives it. At this time, the content providing server also converts the original of the content according to the specifications of the mobile communication terminal occurs. On the other hand, if the content providing server delivers the content source to the CPNS server 100, CPNS server 100 may convert it to meet the specifications of the mobile communication terminal.

The transmission rate checker 140 checks transmission rates of each of the plurality of mobile communication terminals 200 and 300a to 300c to which contents are to be transmitted. Here, the transmission rate of the mobile communication terminal is stored together when storing the information of the mobile communication terminal which is connected to a group by the mobile communication terminal information management unit 120 to transmit and receive information through short-range wireless communication.

The content dividing unit 150 divides the data amount of the content according to each transmission rate confirmed by the rate checking unit 140.

For example, the content dividing unit 150 divides the data amount of the content in proportion to the transmission rate of the mobile communication terminal. When the transmission rate is 100 to the mobile communication terminal having a transmission rate of 1, 200, and the transmission rate to the mobile communication terminal having a transmission rate of 2 The content is divided to transmit 300 to 3 mobile communication terminals and 400 to 4 mobile communication terminals.

The content transmitter 160 transmits the content divided by the content divider 150 to the corresponding mobile communication terminals 200 and 300a to 300c.

The charging processor 170 processes the charging of the mobile communication terminal using the content.

For example, the charging processing unit 170 may use the content alone in the master mobile communication terminal among a plurality of mobile communication terminals, or whether all mobile communication terminals (including both the master and the slave) in the same group use the content. In addition, charges may be imposed.

In addition, the charging processing unit 170 may be charged even when only a portion of the mobile communication terminal in the group uses the content.

Here, the charging processing unit 170 determines whether or not to be charged alone, all or part of the billing based on the billing-related information and the content user information transmitted from the mobile communication terminals 200, 300a to 300c.

The database 180 stores information related to the CPNS server, including the transmission rate of the mobile communication terminal.
