A Command and Dispatch Terminal for Public Network Blind Compensation

Abstract

The invention provides a command and dispatch terminal based on public network blind compensation, which belongs to the technical field of network security. The present invention obtains the CQI value for the network signal quality evaluation of the direct connection between the terminal and the base station in the public network environment; obtains the normalized value of Tb for the MESH data transmission quality evaluation; Connect the MESH ad hoc network strategy of the terminal, and count the CQI value of the terminal participating in the ad hoc network node, use the CQI value and the CQIMax value of the terminal with the strongest signal to perform the networking strategy calculation; normalize the CQI normalized value and Tb Judgment by changing the value, and select different communication strategies, encrypt and decrypt the data in and out of the specified bus interface, and perform hardware encryption and decryption on the data in the data sending and receiving link of the communication unit. The encryption and decryption process is not controlled by the OS layer, and the non-special Data interaction with general equipment in network environment.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a command and dispatch terminal for blind compensation in a public network. Background technique [0002] The dispatch and command business has extremely high requirements on security and controllability. Calls and data need to be kept secret from the outside world, and the network needs strong security guarantees. It also needs to be "manageable and controllable", allowing high-priority users to access the network first. 100% security can only be achieved by using independent network facilities and physical isolation from other networks. Therefore, from the perspective of security, the use of private network communication for dispatching and command services is the only option at present. [0003] Private network communication is a wireless network communication service such as emergency communication, command and dispatch, and daily work communication provided for th...

Problems solved by technology

[0006] 1. The design of the public network communication module is the same as that of general-purpose equipment. It is impossible to avoid data interworking between private network equipment and public network general-purpose equipment from the hardware, and physical isolation cannot be achieved, which poses security risks.
