Two-way selection method for heterogeneous wireless network

Abstract

The invention provides a two-way selection method for a heterogeneous wireless network. The method comprises: a user side receives periodic messages sent by networks and obtains network information from the periodic messages; the network side receives user sending information and obtains user information from the user sending information; the user side evaluates network performances based on the network information and carries out sorting based on the network performances, a network side evaluates utility values of user matching networks based on the user information and carries out sorting on users based on the utility values, the user side and the network side send all information to a matching decision-making engine, and the matching decision-making engine stores all requesting users into a requesting user sorting table and stores all candidate networks into a candidate network sorting table according to a sorting result; and the user side and the network side open matching windows simultaneously, the matching decision-making engine carries out a dynamic matching game on the requesting users and candidate network and sends game results to the user side and the network side. With comprehensive consideration of benefits of the user side and the network side, the user access network efficiency is improved effectively, an access failure rate is reduced substantially, and the user satisfaction degree increases.

Description

technical field [0001] The invention relates to a network access method, in particular to a bidirectional selection method for a heterogeneous wireless network. Background technique [0002] The rapid growth of mobile communication services and the continuous improvement of service quality requirements have prompted the continuous development of wireless communication technologies; different communication systems can provide different communication services, but there are differences between them. For example, although the wide area mobile network can support roaming and mobility, the transmission rate Although the wireless local area network can provide high-speed access services, it does not support handover and roaming. HetNet can play their respective advantages and complement each other; from the perspective of users, heterogeneous multi-networks can achieve seamless coverage and provide users with better communication services. ) guarantees and other aspects are diffe...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, multi-attribute decision-making algorithms are generally used for the selective access of heterogeneous wireless networks. However, the existing methods have the following disadvantages in practical applications: In practical applications, it is inevitable that there will be situations where multiple users initiate service access requests collectively, such as users in vehicles moving from one network to another However, for group access requests or group access requests initiated simultaneously by multiple users in densely populated areas, the existing algorithms will inevitably lead to low access efficiency, high access failure rate, and low user satisfaction, etc.
