PROTECTED RADIO NETWORK FOR BURST DATA TRANSMISSION Russian patent published in 2003 - IPC

FIELD: servicing communication networks, mainly radio ones, for burst data transmission. SUBSTANCE: radio network has at least one network operator's station and plurality of user's stations. One user's station transmits message data directly or through intermediate stations to other user's stations. When station is included in first communication session, it transmits switch request message to operator's station. Other authorized stations will not communicate with new station but they will transfer key request message to network operator's station. The latter will convey desired switches back to new station through other stations so as to enable new station to operate in network. Each user's station periodically transmits switch probing signals to other stations through home open switch. EFFECT: enhanced noise immunity in burst data transmission. 16 cl, 6 dwg
