基于RSS的GSM网络定位技术研究与实现 Abstract:GSMnetworkpositioningtechnologybasedonRSS(ReceivedSignalStrength)isanimportantandwidelyusedlocationmethodinmodernmobilecommunicationnetworks.ThistechnologyusessignalstrengthinformationofmobilestationsintheGSMnetworktodeterminetheirlocation.Inthispaper,wewilldiscusstheGSMnetworkpositioningtechnologybasedonRSS,includingtheprincipleofRSS-basedpositioningtechnology,thefactorsthatinfluencepositioningaccuracy,andtheimplementationofthistechnology. Keywords:GSMnetwork;positioningtechnology;RSS;localizationaccuracy Introduction:GSMnetworkpositioningtechnologybasedonRSSisanimportantmethodofmobilestationpositioningandiswidelyusedinmodernmobilecommunicationnetworks.ThistechnologyuseswirelesssignalstrengthinformationofmobilestationsintheGSMnetworktodeterminetheirlocation.Comparedwithotherpositioningtechnologies,RSS-basedpositioningtechnologyhastheadvantageofhighpositioningaccuracyandlowcost. PrincipleofGSMnetworkpositioningtechnologybasedonRSS: RSS-basedpositioningtechnologyusesmobilestationcommunicationsignalstodeterminethemobilestation'slocation.TheprincipleofthistechnologyistoobtaintheRSSofthemobilestationandthentocalculatethedistancebetweenthemobilestationandthebasestationbasedontheRSSvalue.Accordingtothedistancebetweenthemobilestationandthebasestation,thepositionofthemobilestationcanbedetermined. Factorsthataffectpositioningaccuracy: TheaccuracyofRSS-basedpositioningtechnologyisaffectedbymanyfactors,includingthedistancebetweenthemobilestationandthebasestation,thenumberofbasestationsusedforpositioning,theenvironmentofthemobilestation'slocation,andtheinterferenceofothersignalsinthesamefrequencyband. ImplementationofRSS-basedpositioningtechnology: TheimplementationofRSS-basedpositioningtechnologyinvolvesthreekeyaspects:signalcollection,distancecalculation,andpositioningalgorithm.Inthesignalcollectionprocess,thesignalstrengthofthemobilestationiscontinuouslycollectedbythebasestation.Inthedistancecalculationprocess,thedistancebetweenthemobilestationa
