移动通信系统科技发展迅猛，使之加速了移动通信市场的发展，通信是在195

The rapid development of mobile communication systems technology, making it accelerated the development of the mobile communications market, communications in 1954 due to a "transceiver" and valued by the people of. This is the beginning of the field of communications. Now users have become increasingly high performance and functionality of the mobile communication system requirements. <br>Communications industry has become an inevitable trend of world development, and in-depth understanding of technology is no longer a scholar in the field of communication, something experts, one of the hot but the entire society. In the network using the workers and peasants, the call drop is a hot consumer complaints. This paper describes the development of a simple main CDMA and CDMA technology, focusing on analyzing the reasons caused the workers and peasants of dropped calls, propose solutions based on reason, to achieve the call rate, improve network quality. <br><br><br>Keywords: CDMA network optimization dropped calls

The rapid development of mobile communication system technology has accelerated the development of mobile communication market, communication was paid attention to in 1954 because of the "transceiver". This is the beginning of the communications world. Today's users are becoming more and more demanding on the performance and function of mobile communication systems.<br>The communication industry has become the inevitable trend of world development, and in-depth understanding is no longer the matter of scholars and experts in the field of communication technology, but one of the hot spots of concern to the whole society. In the use of the network in the industrial and agricultural areas, the drop of words is the hot spot of user complaints. The main article briefly introduced the development of CDMA and CDMA technology, focusing on the analysis of the causes of the drop in the industrial and agricultural areas, according to the reasons for the proposed solutions to achieve a high call rate, improve the quality of the network.<br><br>Keywords: CDMA drop-off network optimization

The rapid development of mobile communication system technology has accelerated the development of mobile communication market. Communication was valued by people in 1954 because of "transceiver". This is the beginning of communication. Nowadays, users have higher and higher requirements for the performance and function of mobile communication system.<br>The communication industry has become an inevitable trend of the world development. It is no longer a matter for scholars and experts in the field of communication technology to deepen and understand, but one of the hot spots of the whole society. In the use of the network in the industrial and agricultural areas, dropping calls is the hot spot of user complaints. This paper briefly introduces the development of CDMA and CDMA technology, focuses on the analysis of the causes of dropped calls in the industrial and agricultural areas, and puts forward solutions based on the causes to achieve high call rate and improve network quality.<br>Key words: CDMA dropped call network optimization
