Heterogeneous network access selecting method for pre-screening network based on predictive call blocking rate

Abstract

The invention discloses a heterogeneous network access selecting method for pre-screening a network based on a predictive call blocking rate, and belongs to the technical field of heterogeneous wireless network access. The method mainly comprises three steps: pre-screening of a candidate network, subjective and objective weight combined network preference selection and access execution of an optimal network. The method can effectively remove the networks which are relatively congestive and weak in signals, thereby improving the efficiency that a user selects the optimal network and the quality of service; the optimal network is selected by the traditional subjective and objective combined network preference selection algorithm based on the pre-screened candidate network, and the optimal network is finally accessed according to the judgment result of a network selecting decision. The simulation result shows that the judgment process of the algorithm gives consideration to both of the network state and the user preference, the effects of reducing the ping-pong effect and maximizing the utilization rate of network resources are achieved, and the accuracy and the practicability of network access are improved.

Description

technical field [0001] The present invention relates to the technology in the field of wireless communication, and in particular to a heterogeneous network access selection method based on predicted call blocking rate pre-screening network, which enables users to more effectively select the most suitable network in a heterogeneous wireless network environment. Access to the network for vertical switching. Background technique [0002] With the development of social production and the improvement of people's living standards, our requirements for wireless communication services are getting higher and higher, and we are eager to get better services in terms of content, method and efficiency of information exchange.

Problems solved by technology

[0003] At present, scholars at home and abroad have done a lot of research on the network access selection algorithm, but most of the network selection access algorithms use the "best connection" principle, that is, select the network access with the most suitable performance from several coexisting networks. The goal is to achieve the optimization of business service quality, but it is not conducive to the effective use of network resources.

Moreover, the choice of network access needs to consider factors including business requirements, network performance, user preferences, and mobile terminal characteristics. The complexity is high, so it only stays in the conceptual model stage, and there is still a considerable distance from the actual application
