The new generation of wireless communication not only to achieve the link between people, but also to achieve all things together and diversified business needs, but the traditional networks can’t provide perfect service for a variety of business, the next generation of mobile network alliance to make use of virtualization technology slices the network, which is logically isolated to each other but shares the same physical infrastructure. And the slices are customized for specific on-demand, which makes the business need to select the appropriate slice to get good service. In this paper, a fuzzy matching algorithm based on service is proposed. The proposed scheme is compared with Max-RSRP (Reference Signal Receiving Power). The results show that the proposed algorithm can select the appropriate slices and reduce the number of handover times.
