Congestion Control Algorithm of ANDSF Priority in Heterogeneous Networks

Abstract

In Heterogeneous networks applied ANDSF, UEs select the access network based on priority provided by ANDSF. The congestion network has the lower priority, need to recover the lower priority when congestion is over. In this paper, introduce the recovery method of the lower priority to the default priority based on time value. As a result, the network is able to provide a better QoS with UE, also expected to load balancing of networks.
