Title: An internet voice communication method using WebCallAgent
Inventor: CHOI JAE EUN
IPC: H04L12/66
Filed: 2001-01-03
Abstract: PURPOSE: An Internet voice communication method in a private network using a Web call agent is provided for users to listen to a voice transmitted from the other party by allocating a public Internet protocol and a port in advance from a router for an address/a port of a channel for transmitting a voice of a Web terminal user to the other party and receiving the voice of the other party when the Web terminal user who has been allocated with a private Internet protocol communicates in voice in a Web to Phone form with the other party. CONSTITUTION: WebCallClient(10) existing in a router initiates a transmission control protocol communication with a WebCallAgent(30) through a router(20)(S201). The WebCallClient(10) transmits a user datagram protocol packet to the WebCallAgent(30)(S202,S203). The WebCallAgent(30) obtains a source address and port information from a header of a packet, carries them on the user datagram protocol packet in a message form and transmits them to the WebCallClient(10)(S204,S205). Then, the WebCallClient(10) recognizes a public Internet protocol and a port allocated from the router(20) according to the user datagram protocol packet communication(S206), replaces the recognized address information with its own voice receiving channel information and transmits it to the WebCallAgent(30)(S207,S208). The WebCallAgent(30) and a gateway(40) perform call signaling(S209), and the WebCallClient(10) receives a channel address to be received by the gateway(40)(S210,S211). Then, the WebCallClient(10) transmits a voice to a receiving channel address of the other party and the voice reaches the other party(S212,S213). When the gateway(40) transmits the voice to the public Internet protocol and the port received from the WebCallAgent(30), it reaches to the WebCallClient(10) through the router(20), so that the voice of the other party can be listened to(S214,S215).
