Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] image 3 It is a block diagram of the point-to-point communication system based on the mail server of the present invention.

[0026] See image 3 , point-to-point communication system of the present invention comprises a plurality of communication terminals 2 with dial-up device, and each communication terminal has unique ID number, and the dial-up device commonly used at present has modem (by fixed telephone dial-up), GPRS Modem or CDMA Modem, wherein , the modem, GPRS Modem or CDMA Modem can be built in the communication terminal, and can also be externally connected to the serial port of the communication terminal 2. Since there are many dialing devices available now, it is easy to expand the system by selecting an external connection method, and provide users with more choices. Each communication terminal obtains a dynamic IP address afte...

Abstract

The invention discloses a dynamic IP-based peer-to-peer communication system and a communication method thereof. The communication system comprises a plurality of communication terminals with dialing devices, wherein each communication terminal has a unique ID number; and the communication system also comprises mail servers; the communication terminals are connected with the mail servers after networking by dial up; and dynamic IP switching is finished by the mail servers after the communication terminals network by dial up. The communication system and the communication method provided by the invention can realize the address switching of a dynamic IP simply without adding equipment, thereby reducing the cost.

Description

technical field [0001] The present invention relates to a communication system and its communication method, in particular to a dynamic IP-based point-to-point communication system and its communication method. Background technique [0002] Communication systems mainly include client / server networks and peer-to-peer networks. figure 1 is a block diagram of an existing server-based communication system, see figure 1 , the central server 1 respectively establishes connections with the communication terminals 2, and there is no need to directly establish point-to-point communication between each communication terminal, wherein the central server 1 generally selects a computer with relatively strong performance. At present, various remote detection systems, remote control systems and remote data acquisition systems generally use a central server to build a communication system. There are four ways to access the central server: 1) The central server uses a public network fixed I...
