Abstract


With the 2008 acquisition of China Unicom 's CDMA network of China Telecom , China Telecom 's CDMA network scale is expanding , a sharp increase in the number of users , users of network performance and network quality requirements is also rising , the CDMA network optimization technology is becoming a mobile communication network optimization engineers are concerned new direction . The papers focus on analysis of the problems and causes of the failure of the CDMA network switch , soft handover specific key technologies of the CDMA system is a wireless system resources and optimize focus , soft - switching algorithm and parameter settings directly affect the capacity of the system and the quality of service . The comprehensive overview of the algorithms and principles of the several switching ( soft handover , idle handoffs , hard handoff , the access switch ), and comparison of various implementations , highlighting the scope of the various programs . The Hainan Branch of China Telecom 's CDMA - based network , the paper focuses on how to improve the CDMA network optimization handover success rate , play a guiding role on the handover failure cause analysis to solve the CDMA network run . By theoretical analysis of the CDMA networks DT data show that the handover success rate has a significant role and significance for improving the quality of the network by increasing the CDMA network .
