Title:AnalysisofCDMANetworkMobileTerminalCallFailures
Abstract:
TheCodeDivisionMultipleAccess(CDMA)networkhasbecomeincreasinglypopularinmobiletelecommunicationsasitoffersseveraladvantagessuchasincreasedcapacity,improvedcallquality,andenhancedsecurity.However,likeanyothernetworktechnology,CDMAnetworksarenotimmunetocallfailures.ThispaperaimstoanalyzethecausesofcallfailuresinCDMAnetworkmobileterminalsandprovidessuggestionsforimprovingcallsuccessrates.
1.Introduction
TheintroductionwillprovideabriefoverviewofCDMAtechnologyanditssignificanceinmobiletelecommunications.Itwillhighlighttheimportanceofunderstandingtheunderlyingissuescausingcallfailurestoimprovenetworkperformance.
