Security and protection communication method based on VoIP

Abstract

The invention discloses a security and protection communication method based on a VoIP. The security and protection communication method based on the VoIP is characterized in that communication terminal nodes are connected through the Internet to achieve voice communication between the communication terminal nodes, the communication terminal nodes are enrolled into corresponding interaction joint defense sets, interaction joint defense set information is stored in a foundation database, and accordingly the interaction joint defense function can be achieved. According to the security and protection communication method based on the VoIP, the one-to-many mode from a server to communication terminals is established, in the type information pushing process, a fast information transmission channel can be provided, and emergency broadcasting can be notified in time; multiple functions are fused together, under the condition that the communication terminals do not need to be greatly adjusted, an existing network environment can be used for achieving emergency broadcasting, and the communication function, the interaction joint defense function and the message leaving function can be achieved by the way that the terminals make calls; moreover, the security and protection communication method based on the VoIP is good in universality and high in communication stability.

Description

technical field [0001] The invention relates to a VoIP-based security communication method. Background technique [0002] 1. VoIP telephone is a new business of voice communication through Internet technology or network. The biggest advantage of VoIP is that it can widely use the Internet and the global IP interconnection environment to provide more and better services. Traditional telephones use the public telephone network as the medium for voice transmission, while IP telephony converts voice signals between the public telephone network and the Internet, compresses and encapsulates voice signals, and converts them into IP packets. At the same time, IP technology allows multiple users to Sharing the same bandwidth resources has changed the way that a single user monopolizes a channel in traditional telephony, saving users the cost of using a separate channel. In the current communication system, the communication terminal has the function of realizing general communicatio...

Problems solved by technology

The present invention adopts the open standard protocol to expand the function conveniently, and it can be deployed by using the coverage of the network, and the network resources can be fully utilized; but the defects in the method of the joint defense alarm are: 1. Compared with the voice protocol in the patent, it is not open and standard, The expansion of system access and applications on other platforms brings complexity and infeasibility, and proprietary protocols increase the cost and difficulty of system transformation; 2. The comparison patent does not define the processing of the system when encountering large concurrent communications , and there is no data disaster recovery strategy, so when the communication reaches the peak value, it will lead to system instability, resulting in the inability to realize the emergency function
