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

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

Thereafter, when the mobile communication terminal 200 receives the service request transmitted to the end terminal, the mobile communication terminal 200 checks whether the end terminal is capable of CPNS service (S30).

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

When the terminal 300 receives the authentication message that the CPNS service is available from the mobile communication terminal, and transmits its ID (S50).

The mobile communication terminal 200 checks whether the format of the ID transmitted from the terminal 300 matches the ID format issued by CPNS, and if the format matches, the service is transmitted to the terminal 300. The authentication message is transmitted (S60, S70).

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

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

If the service is available to both the mobile terminal and the end terminal, the CPNS server 100 notifies this to the end terminal so as to perform a CPNS service including a content request afterwards (S100).

If any one of the mobile communication terminal and the terminal terminal is not available, the CPNS server 100 notifies this to the terminal terminal and terminates the service.

On the other hand, when the CPNS service of the terminal terminal is impossible as a result of checking in step S30, the mobile communication terminal 200 transmits a message that the service is not available to the terminal terminal 300, and terminates the service.

On the other hand, if the ID format of the terminal does not match, as a result of checking in step S60, the mobile communication terminal 200 transmits a message indicating that the service is unavailable to the terminal, and then terminates the service.
