Patent ID: 8656028

Claim:
A communication connection system, comprising: a first system composed of (i) a connection server and (ii) a support terminal not having a global address; and a second system composed of (i) a user terminal not having a global address and (ii) a polling server, the first system and the second system being connected through a public line network, wherein the connection server includes: a terminal identification data receiver receiving terminal identification data for identifying a user terminal requesting to connect with the support terminal, and a connection request receiver receiving connection request data indicating connection request from the support terminal to a user terminal identified by the terminal identification data when the terminal identification data is received, the polling server includes: a polling transmitter periodically conducting polling to the connection server to check if the connection server has received the connection request data, and a connection request data transmitter transmitting the connection request data when the polling transmitter determines that the connection server has received the connection request data, and the user terminal includes a communication bus communicating with the support terminal through the polling server and the connection server by a predetermined communication application when the user terminal receives the connection request data; wherein the communication connection system is constructed and arranged to: send a user of the user terminal a message providing a unique telephone number to be called to obtain support; store the unique telephone number, along with other unique telephone numbers, in a table on an authentication server, the table associating each telephone number with a respective public IP address of a polling server and with a respective private IP address of a user terminal; receive a telephone call from the user to the unique telephone number previously sent to the user; and access the table to identify the public IP address of the polling server and the private IP address of the user terminal associated with the called telephone number; wherein the terminal identification data receiver receiving, by the connection server, terminal identification data includes receiving the public IP address of the polling server and the private IP address of the user terminal identified from the table.
