Method and system for establishing connection to called terminal
First Claim
1. A method for connecting a calling terminal to a called terminal, comprising:
- establishing a first session to a video server and a call connection request to the called terminal;
receiving ringback tone (RBT) video data from the video server using the first session to the video server during a first waiting time, the first waiting time being a time before a response from the called terminal for establishing a second session is received in response to the call connection request;
generating a setup flag to set a connection environment with the called terminal to perform a fast setup between the calling terminal and the called terminal; and
transmitting the setup flag to the called terminal through the second session established by the called terminal.

Abstract
A method for connecting a calling terminal to a called terminal includes establishing a first session to a video server and a call connection request to the called terminal, receiving ringback tone (RBT) video data from the video server using the established first session during a waiting time before a response from the called terminal for the request is received, generating a setup flag to set a connection environment with the called terminal to perform a fast setup between the calling terminal and the called terminal, and transmitting the generated setup flag to the called terminal through a second session established by the called terminal. A system to perform the method includes an establishing unit to establish the first session, an RBT video data receiving unit to receive the RBT video data, a setup flag generating unit, and a setup flag transmitting unit.
