SOLUTION: There are provided the communication terminal 10 capable of receiving service from a service providing server 30, a communication terminal 20 for receiving the service instead of the communication terminal 10, and the connection device 100 for connecting the service providing server 30 to the communication terminal 20. The connection device 100 generates session information related to a session when the session with the communication terminal 10 is established for transmitting to the communication terminal 10, the communication terminal 20 is authenticated based on the session information transmitted from the communication terminal 20 via the communication terminal 10, and the service providing server 30 is connected to the communication terminal 20 when the authentication succeeds and the session with the communication terminal 10 is being established.
