Abstract

The invention requests to protect an intelligent access method for comprehensive benefit maximization in a heterogeneous wireless network, and provides an intelligent access algorithm for comprehensive benefit maximization in order to solve the problems of frequent access and lack of access strategy adjustment according to the moving speed of a user in a current access algorithm in the heterogeneous wireless network. The method comprises: firstly, calculating the maximum transmission rate of a user according to the received signal strength and the available bandwidth of the user and using themaximum transmission rate as the current benefit; secondly, obtaining the transmission rates of the user at the next several moments through a prediction method, and taking the transmission rates as long-term benefits in combination with a weight decreasing method; and finally, combining the current benefit with the long-term benefit according to the moving speed of the user. Experimental resultsshow that the access frequency can be effectively reduced, the system throughput is improved, and the method is suitable for user access at different moving speeds.

Description

technical field [0001] The invention belongs to an access method in a heterogeneous wireless network and belongs to the field of mobile communication. In particular, it relates to an intelligent access algorithm for maximizing comprehensive benefits in heterogeneous wireless networks. Background technique [0002] With the rapid development of wireless network technology, the next generation network will be a heterogeneous wireless network composed of multiple wireless access technologies. Users can choose more diverse networks for access. Since different types of networks have great differences in coverage and user experience, research on stable, efficient, and seamless access network selection methods for users has become a hot issue at present. . [0003] The literature [Yu H, Ma Y and Yu J, Network Selection Algorithm for Multiservice Multimode Terminals in Heterogeneous Wireless Networks[J], IEEE Access, 2019, 7:46240-46260] proposes a multi-service multimode terminal...
