Method and apparatus for transmitting categorised information at frequencies dependent on the category the information is placed in

摘要

Information (1) transmitted through wireless communication formed by the information transmission line from the artificial satellites and the radio towers or through wired communications established by cables is categorised into four categories. The categories indicate the urgency of the information, and thus indicate the timing intervals at which the information is transmitted. Category 4 (2) is transmitted with the highest priority immediately when the information is generated. Category 3 (3) is transmitted periodically, for example every five minutes. Category 2 (4) information is transmitted when the transmission line is relatively unoccupied and Category 1 (5) information gets transmitted only when the transmission line is least occupied.
