1. A method of providing a collect call service based on a voice over Internet Protocol (VoIP) system, the method comprising:
- establishing a first communication link between a called gateway and a collect call switch, on receiving a collect call request from a caller terminal via a VoIP network located between i) a calling gateway being coupled to the caller terminal and ii) the called gateway being coupled to the collect call switch, wherein the caller terminal can access the called gateway by use of already-known access information;
establishing a second communication link between the collect call switch and the called terminal;
connecting the first communication link and the second communication link to initiate a billing process for the second communication link responsive to a collect call acceptance in the form of a dual tone multi-frequency (DTMF) signal from the called terminal; and
releasing the connected link to end the billing process responsive to a normal call end request from one of the caller terminal and the called terminal.

Abstract
One embodiment of the present invention provides a collect call method and system thereof, more particularly, in order to charge the called party with a uniform toll for collect call, which is determined by only the type and location of called party terminal. In one embodiment, the collect call method, system and a counsel service providing method use a free VoIP network for part of the voice call link and a charge PSTN network for the rest of the voice call link. In one embodiment, if the first link corresponding to the collect call request is established, the collect call switch calls the called party terminal to establish the second link, and billing on the second link is initiated.

7. A method of providing a collect call service based on a voice over Internet Protocol (VoIP) network, the method comprising:
-
performing i) an authentication of a caller terminal and ii) a Registration/Admission/Status (RAS) approval of a collect call request upon receiving the collect call request from the caller terminal that already knows access information of a VoIP collect call system, and acquiring access information of a called gateway corresponding to a called terminal;
connecting a calling gateway and the called gateway by sending the collect call request to the called gateway if RAS approval and access information of the called gateway are acquired;
establishing a first communication link between the called gateway and a collect call switch responsive to the collect call request;
establishing a second communication link between the collect call switch and the called terminal;
connecting the first communication link and the second communication link to initiate a billing process for the second communication link responsive to a collect call acceptance in the form of dual tone multi-frequency (DTMF) signal from the called terminal; and
releasing the connected link to end the billing process responsive to a normal call end request from one of the caller terminal and the called terminal. - View Dependent Claims (8, 9, 10)

11. A collect call system based on voice over Internet protocol (VoIP), comprising:
-
a called gateway, being in signal communication with a calling gateway via a VoIP network, configured to establish a VoIP link to the calling gateway on receiving a collect call request from a caller terminal via the VoIP network, wherein the caller terminal can access to the called gateway by use of already-known access information; and
a collect call switch, being in signal communication with a called terminal via one of a public switched telephone network (PSTN) and a mobile network, the collect call switch being configured to establish a first communication link to the called gateway and a second communication link to the called terminal responsive to the collect call request, to connect the first communication link and the second communication link responsive to a collect call acceptance from the called terminal, and to perform a billing process for the second communication link. - View Dependent Claims (12)
