Embodiment

[0060] This embodiment follows the architecture of the IEEE1900.4 standard, such as figure 1 Shown. according to figure 2 The terminal reconfiguration based on fuzzy optimization theory in a software radio environment is shown. The specific method is detailed as follows:

[0061] Step 1. The terminal obtains various attribute parameters of the corresponding network, such as the throughput and security of the network, from the network reconstruction manager;

[0062] Step 2: According to the different QoS requirements of users, the expert scoring method is used to determine the weights of various attribute parameters. These weights reflect the importance of different QoS requirements to different performances. The expert scoring method analyzes the weight through continuous feedback and adjustment.

[0063] Assuming there are m attributes and k experts, first construct a judgment matrix:

[0064] W = w 11 w 12 . . . w 1 k w twenty ...

Abstract

The invention discloses a terminal reconfiguration method based on a fuzzy optimization theory in software radio environment. The terminal reconfiguration method is characterized by comprising the following steps of: (1) acquiring attribute parameters of a coverage network in an area where a current terminal is located from a network reconfiguration manager (NRM) by using a terminal reconfiguration manager (TRM) of the current terminal; (2) determining the weights of the attribute parameters of the coverage network by using an expert scoring method, dividing all reconfiguration schemes into high-class schemes and low-class schemes by configuring a characteristic value index membership degree matrix, and calculating the goodness and badness of each reconfiguration scheme; and (3) calculating the membership degree of each scheme according to the goodness and the badness, and determining an optimal reconfiguration scheme according to a membership degree maximization principle. By adoption of the method, scheme difference can be obviously embodied, and the uniformity of an evaluation result is avoided. The method has the advantages of simplicity in calculation, practicability and wide application prospect. The evaluation process and the evaluation result have obvious physical meanings.

Description

Technical field [0001] The present invention belongs to the technical field of telecommunications and relates to a terminal reconstruction method based on fuzzy optimization theory in a software radio environment, and more particularly to a terminal reconstruction method based on multi-objective fuzzy decision-making under the IEEE 1900.4 framework. Background technique [0002] With the continuous development of wireless network technology, the same area may be covered by multiple wireless networks (such as WiFi, WiMax, wireless LAN, etc.). These wireless networks are composed of computers, network equipment, and systems produced by different manufacturers. Most of them run on different communication protocols and support different functions, services, and applications. [0003] The current multi-mode mobile phone technology enables mobile phones to switch between networks of different technical standards in real life. This technology allows the mobile phone to support a variety ...
