How to design an ultra-dense heterogeneous wireless network selection algorithm to improve the network access security level and improve the quality of user experience in the network selection process has become a hot issue in current research. In order to improve terminal security and end user experience, this paper designs a network slice selection algorithm based on SDN and terminal security. At the same time, considering the possible negative unevenness between the two kinds of slices, an adaptive slice adjustment mechanism is proposed. Combined with data transmission rate and access blocking rate, the comprehensive benefit function is constructed, and the optimal slice resource allocation strategy is solved by ant colony optimisation algorithm, and then the optimal access slice of the terminal is designed. The experimental results show that the algorithm can reduce the access blocking rate and average load of the network, and effectively improve the service satisfaction of users. Therefore, the algorithm model proposed in this paper can provide a reliable reference for the subsequent terminal security network selection model, and also provide a more reliable network foundation for end users.
