PTT DISPATCHING SYSTEM AND A REMOTE-DESTROYING KEY METHOD THEREOF

摘要

A remote-destroying key method in a PTT dispatching system is provided in the present invention, in which the PTT dispatching system performs encryption call management to a PTT terminal equipped encryption module and includes the following steps: A1. the PTT dispatching system initiating a remote-dispatching key request to certain PTT terminal; B1. obtaining a call information corresponding with the PTT terminal according to the remote-destroying key request so as to establish a call channel with the PTT terminal; C1. generating a remote-destroying key instruction to destroy the encryption module of the PTT terminal; D1. sending the remote-destroying key instruction to the PTT terminal so as to destroy the encryption module. A PTT dispatching system for realizing remote-destroying key of a terminal is also provided in the present invention. In the present invention, the encryption module of the terminal could be destroyed instantly, which insures real time privacy of an encryption call.
