Visible telephone communication method and coding communication system based on internet

Abstract

The visible telephone communication system includes several visible telephone sets connected with Internet and at least one encoding transmission terminal in hierarchical gateway structure. The communication method includes: numbering the hierarchies of the gateway structure and numbering all the visible telephone sets; initiating the visible telephone set via registering the number and the IP position in relevant lowest hierarchy gateway in the transmission terminal based on the area; dialing in the caller side for talking via looking up the registered number of the callee in the transmission center and connecting to the IP position of the callee in the Internet; talking and transmitting image information via Internet. The system is superior to available system and may be used in all places with Internet.

Description

technical field [0001] The invention belongs to the technical field of Internet telephony, in particular to an Internet-based videophone communication method and a coding communication system thereof. Background technique [0002] Video phone, IP phone and VoIP phone are all network communication solutions based on the Internet and implementing the communication protocol (TCPIP). They transmit voice signals on the Internet to reduce communication costs. [0003] But the existing videophone terminals must have fixed IP addresses that both parties have on the Internet before they can make a call. If one or both parties have non-fixed IP addresses, they cannot connect. In this case, the fixed IP greatly increases the cost, and the complexity of the IP address and people's incomprehension directly affect the popularity of video TV. [0004] However, IP phones and VoIP phones require a fixed phone number on both sides to transmit signals, which relatively increases the cost and...

Problems solved by technology

In this case, the fixed IP greatly increases the cost, coupled with the complexity of the IP address and people's incomprehension, directly affects the popularity of video TV.

[0004] However, IP phones and VoIP phones require a fixed phone number on both sides to transmit signals, which relatively increases the cost and complexity of system installation, and more importantly, wastes bandwidth on the Internet.

The numbers of IP phones and VoIP phones are long, which is inconvenient to memorize and troublesome to dial
