Aggregating bandwidth from multiple Radio Access Technologies (RATs) provides an opportunity for network providers to enhance network capacity. This is important for serving applications that require more bandwidth than a single RAT can offer. One of the important elements of bandwidth aggregation is the selection of a suitable set of RATs to achieve efficient aggregation. In this paper, the authors propose a multi-radio access selection scheme for selecting an appropriate set of RATs to achieve the desired bandwidth aggregation for a connection request initiated by a multi-homed terminal in a heterogeneous wireless network.
