METHOD OF JAMMING OF COMMUNICATION CHANNELS Russian patent published in 2003 - IPC

FIELD: radio engineering, selective jamming of users of present-day radio networks with macro and microcellular structures. SUBSTANCE: invention refers to equipment forming deliberate jamming. Technical result is development of method of selective jamming of subscriber with specified number, creation of effective interference achieved thanks to utilization of information transmitted by network proper in common signaling channel and in calling channel, formation and transmission of interference radiation on transmission frequency of subscriber in the form of control signal of termination of communication session on behalf of subscriber with specified number. Method includes processes of multiple reception of messages sent over above-mentioned channels, bit-by-bit recording of service frames, isolation of information part and reading of subscriber's number and value of channel number assigned for present communication session from it, determination of transmission frequency of mobile subscriber and formation of jamming on given frequency in the form of control signal of termination of communication session on behalf of subscriber with specified number. EFFECT: development of method of selective jamming of subscriber with specified number. 7 dwg
