Comparison Research on Heterogeneous Wireless Network Access Strategy

In view of the present heterogeneous wireless network access selection algorithm have various kinds and different function,in order to solve the problem of mobile terminal of heterogeneous wireless net- work performs the optimal network access at any time and any place.This paper first briefly introduces the heterogeneous wireless network,secondly,according to the difference of optimization goal divide heterogeneous wireless network access selection algorithm into two kinds of based on decision factors access se- lection algorithm and based on the mathematical model access selection algorithm.in the final analysis of the current domestic and foreign heterogeneous wireless network access selection algorithm research;the existing heterogeneous wireless network access selection algorithm in business type,user strategy and net-work security are discussed.To choose the right heterogeneous wireless network selection algorithm provides effective basis and reference significance.
