Abstract


China 's three major carriers , China Mobile and China Unicom , responsible for the construction and maintenance of the GSM network , and the main profit comes from the GSM network . In the performance evaluation of a cellular communication system such as the GSM , forced to interrupt the ongoing call more intolerable than blocking new calls , so when the user moves from one cell to another cell , to make great efforts to maintain the continuity of a call in progress , in order to ensure the mobility of the user during the call . The switch is a critical mobility management functionality , it is guaranteed that the user in a mobile communication network having a mobility essential . The pros and cons of switching technology directly affect the level of quality of service provided by the system , thus affecting the degree of trust of users on the carriers . This paper describes the GSM system to switch the meaning and context of the research , which leads to the classification as well as the different scenes of the switch to switch the signaling process . Finally , switching algorithm on the basis of comprehensive domestic manufacturers to adopt , summed up the papers now switching algorithm . The switching algorithm, the handover trigger causes the switching algorithm processes under different scenarios , and gives the recommended setting value of the switching parameters in the different handover scenarios . According to the data obtained by the lab debug , switch the effectiveness of the algorithm and the parameters set reasonable verification . Finally, this paper summarizes proposed continue to study later in this paper focus on the content .
