Abstract
With the development of public security private network communication, the traditional narrowband Police Digital Trunking (PDT) network is difficult to meet the requirements of image and video transmission. As a broadband trunking network, Broadband Trunking Communication (B-TrunC) fills the gap of broadband wireless network in private network communication. How to realize vertical handover between two heterogeneous networks in terminals has become the focus of research. In this paper, a subjective weight method based on Triangular Fuzzy Number (TFN) and an objective weight method based on Rough Set Theory (RST) are proposed. Among several attribute parameters affecting network performance, the weight of each attribute is determined, which provides a theoretical basis for network vertical handover.
