First, the end device 300 searches for a mobile communication terminal, which will function as a PN gateway device, in order to use a CPNS service at step S10.
Next, the end device 300 requests the service from the mobile communication terminal 200 that has been found at step S10. Here, the end device also transmits CPNS-availability information to the mobile communication terminal 200 at step S20.
Thereafter, when the mobile communication terminal 200 receives a service request transmitted from the end device, the mobile communication terminal 200 checks whether the CPNS service is available to the end device at step S30.
If, as a result of the checking at step S30, the CPNS service is determined to be available to the end device, the mobile communication terminal 200 transmits an authentication message, indicating that the CPNS service is available to the end device 300, to the end device 300 at step S40.
When the authentication message, indicating that the CPNS service is possible, is received from the mobile communication terminal, the end device 300 transmits its own ID to the mobile communication terminal at step S50.
The mobile communication terminal 200 checks whether the format of the ID received from the end device 300 is consistent with an ID format issued by the CPNS server, and transmits an authentication message, indicating that the service is available to the end device 300, to the end device 300 if the formats are consistent with each other at steps S60 and 70.
Thereafter, the mobile communication terminal 200 transmits its own authentication information and ID and the authentication information and ID of the end device 300 to the CPNS server 100 at step S80.
The CPNS server 100 determines whether the CPNS service is available to both the mobile communication terminal and the end device by checking the authentication information and IDs received from the mobile communication terminal at step S90.
If, as a result of the determination, the service is available to both the mobile communication terminal and the end device, the CPNS server 100 informs the end device that the service is available to the end device so that the end device can perform a CPNS service procedure, including a subsequent content request, at step S100.
