Abstract
At present, China’s police mobile communication network mainly includes Police Digital Trunking (PDT) and Broadband Trunking Communication (B-TrunC) networks. It is an urgent task to build a heterogeneous network of broadband and narrowband networks under the background of mobile Internet. Vertical handover technology is an indispensable key technology in heterogeneous networks. According to the characteristics of private network communication, this paper divides the services into four types, and then calculates the subjective weight and objective weight of each network attribute. And a Technology for Order Preference by Similarity to an Ideal Solution algorithm based on Kullback-Leibler divergence (KL-TOPSIS) is proposed to sort candidate networks. Simulation and numerical results show that this algorithm has better vertical handover performance under different services.
