Embodiment Construction

[0073] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0074] The application scenario of the present invention is considered as a heterogeneous network composed of PDT, B-TrunC, and WLAN. The system model is as follows figure 2 shown. In this heterogeneous network, PDT, B-TrunC, and WLAN overlap with each other. Among them, the PDT network has the widest coverage, B-TrunC is the second, and the WLAN network has the smallest coverage. User terminals have the opportunity to connect to the three networ...

Abstract

The present invention proposes a vertical switching method based on relative entropy and ideal solution in a dedicated fusion network, the method described in the method includes step 1, using the analytic hierarchy process to calculate the subjective weight of the network attribute; step 2, using the entropy value method Calculate the objective weight of network attributes; step 3, perform candidate network sorting based on relative entropy and ideal solution similarity sorting method, and determine the best switching network according to the candidate network sorting order; vertical The handover method has better handover decision performance than the traditional simple weighting method.

Description

technical field [0001] The invention belongs to the technical field of public security private network selection, in particular to a vertical switching method based on relative entropy and ideal solution in a private fusion network. Background technique [0002] In special scenarios such as natural disasters, terrorist attacks, public emergencies or large-scale event security, the existing public network may not be able to ensure timely command and dispatch communication requirements due to its poor confidentiality and high network load. , so it is necessary to build a stable and efficient private network. A dedicated mobile communication network can provide a high-reliability command and dispatch service for specific user groups to meet the communication requirements of a wireless communication network under special circumstances. At present, China's police mobile communication network mainly includes Police Digital Trunking (PDT) and Broadband Trunking Communication (B-Tr...
