Abstract


An important feature of the PHS system , is due to the low transmission power of the PHS base station decided PHS system is only suitable for micro- cellular manner networking for the PHS system must be installed on a large number of micro- cellular base station (500mW and 10mW base station ) . PHS system, the same with the other mobile network the network Diaohua problem because the PHS system uses a micro-cellular structure , the PHS network users than any other mobile network , there are more switching phenomena Therefore, how to improve the PHS network Diaohua becomes more important . This paper describes the technical characteristics of the PHS network , various system parameters , focusing on the analysis of the reasons for the phenomenon of the PHS network dropped calls , as well as how to find to solve the problem of dropped calls in different objective environmental conditions . And std-28 protocol - based process in accordance with the relevant agreement , the focus of the study is a call dropped calls , is characterized by close to reality , operability , the comprehensive all possible analysis and solve problems . This dissertation research study similar to the communication quality of the micro- cellular communication system has certain reference value and guiding role .
