Embodiment Construction

[0024] Aiming at the problem that the heterogeneous network access selection method in the traditional technology cannot well satisfy users' requirements for different service QoS, the present invention proposes a wireless heterogeneous network access selection method. This method uses the decision function that includes business type distinction to make a decision, and uses the Analytic Hierarchy Process (AHP, The Analytic Hierarchy Process) to calculate the decision factors respectively in the session class and interaction class defined by the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project). The weights in the four types of business, class, flow class and background class. Select the weight value of each decision factor according to the business type, combine the normalized network parameter values ​​(bandwidth, end-to-end delay, bit error rate and service fee), and substitute it into the network selection decision function to calculate the cost ...

Abstract

The invention relates to a wireless communication technique, in particular relates to a method for selecting the wireless heterogeneous network access. The invention aims at solving the problem that the conventional method for selecting the heterogeneous network access can not favorably meet the QoS (Quality of Service) requirement of users for different services. The main points of the technical scheme are as follows: selecting a judgment factor in the network parameter; constructing a network access selection judging function; calculating the weight value of the judgment factor in various types of services; when a service reaches, substituting the normalized network parameter value into the network access selection judging function based on the weight value of the judgment factor in the service to calculate the cost of the alternative network; and selecting the alternative network with the least cost for access. According to the invention, users can be accessed to the optimum network by utilizing the performance advantage of the heterogeneous network in case that the heterogeneous network is overlapped.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a wireless heterogeneous network access selection method. Background technique [0002] With the development of mobile communication technology, the next-generation mobile communication network will be a broadband, ubiquitous and collaborative heterogeneous fusion network that integrates various types of wireless broadband access technologies and adapts to communication requirements of different distances, speeds and service levels. . It mainly includes wireless broadband access technologies represented by IEEE802 series standards, such as Wireless Personal Area Network (WPAN, Wireless Personal Area Network), Wireless Local Area Network (WLAN, Wireless Local Area Network), Wireless Metropolitan Area Network (WMAN, Wireless Metropolitan Area Network), and common wide-area cellular mobile communication networks (typical cellular systems such as 2G / 3G / B3G, etc.). These differen...
