- RAU CONTROL BAND ANTI-JAMMING METHOD IN RADIO COMMUNICATION SYSTEM

摘要

PURPOSE: A control band anti-jamming method for an RAU(Radio Access Unit) in a wireless communication system is provided to effectively treat jamming when generating the jamming by ill will in a uniform band by changing the control band in all RAUs per a uniform time. CONSTITUTION: A time synchronous unit obtains initial time information using a GPS receiver, reflects obtained initial time information to an RTC of an internal clock, and determines a control band(5a-5c). Ping and pong maps are initialized using the result value, and a current time is inserted into a control packet transmitted from an RAU and the control packet is transmitted(5d,5e). A CPU confirm whether the current time is a hop update time, and checks whether time change by minute unit exists when the current time is not the hop update time(5f,5i). If the current time is the hop update time, a ping/pong flag is set for activating a desired hop map, and the hop map used when performing hop update is initialized(5g,5j).
