CONNECTION METHOD, CONNECTION SYSTEM, PORTABLE TERMINAL, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2016/042764

Kind Code:

A1

Abstract:

The present invention provides a connection method with which it is possible to reconnect to a communication counterpart in a shorter time even if the IP address of one terminal is changed and communication is cut off during direct communication on mutually equal terms. This connection method is for cases in which a customer-premises terminal is connected to a customer-premises router connected to a first network. The connection method includes: an acquisition step in which a portable terminal acquires, from a support server connected to the first network, connection information used for connection in order for the portable terminal to communicate directly with the customer-premises terminal; and a storage step in which the connection information acquired at the acquisition step is stored in the portable terminal. The connection information includes a port number and an IP address set in the customer-premises router so as to correspond to the customer-premises terminal.
