The limited transmission capacity of traditional cellular networks can not meet the demand of the rapidly growing mobile data traffic. The scheme of intensive deployment of Femtocell can alleviate network pressure, but it also brings some problems, such as frequent handover, ping-pong effect and so on. This paper proposed an adaptive based on type of service handover algorithm to solve above problems. This algorithm not only considers the types of service, but also considers the influence of the neighboring list and the SINR value on the RSS value, which greatly reduces the handover times and the rate of handover failure. The simulation results show that it has achieved about 15% in reducing the probability of handover failure and about 13% in improving total system throughput.
