Abstract

The present invention relates to a method of establishing a communication session passing through a relay server between a mobile terminal capable of connecting to a wireless network at a remote site and a user terminal connected to the Internet, in which if the relay server or a reception server connected to the relay server transmits information on a connection target mobile terminal to a push server providing a push service in response to a request of the user terminal, an agent installed in the mobile terminal actively connects to the relay server in response to a call of the push service, and the relay server establishes a communication session between the user terminal and the mobile terminal. A communication session can be efficiently established for a mobile terminal to which a static IP address is not assigned, and thus communication load can be drastically reduced, and power and resources of the mobile terminal can be efficiently utilized.

A method of establishing a communication session passing through a relay server 31 between a user terminal 10 and a mobile terminal 50 using active connection of the mobile terminal to the relay server, in a configuration including the user terminal 10 and the relay server 31 connected to an Internet and the mobile terminal 50 of a remote site connected to a wireless network 20 and constructing a terminal database 35 connected to the relay server 31 and a push server 40 connected to the wireless network 20, the method comprising the steps of:

transmitting terminal information and call information to the relay server 31 through the wireless network 20 by an agent installed in the mobile terminal 50;
recording the transmitted terminal information and call information in the terminal database 35 by the relay server 31;
transmitting user information to the relay server 31 by the user terminal 10 and, if the user information is valid, accepting connection of the user terminal 10 by the relay server 31 and establishing a communication session between the user terminal 10 and the relay server 31;
requesting connection to the mobile terminal 50 by transmitting the terminal information to the relay server 31 by the user terminal 10;
retrieving the call information of the mobile terminal 50 requested to be connected from the terminal database 35 and transmitting the call information to the push server 40 by the relay server 31;
transmitting the connection information to the agent of the corresponding mobile terminal 50 through a push service by the push server 40 receiving the call information;
connecting to the relay server 31 by the agent of the mobile terminal 50 receiving the connection information and establishing a communication session between the mobile terminal 50 and the relay server 31;
and
concatenating the communication session between the user terminal 10 and the relay server 31 and the communication session between the mobile terminal 50 and the relay server 31 by the relay server 31.
