There are three main themes which are investigated. The first theme is about Always-Best-Connected access network where the network selection process is improved by taking into account factors suchaslinkquality,applicationorserviceused,linkcost,locationdataandband- width. Thenetworkselectionalsofollows3GPPEPCANDSFinformationwhen- ever it is available, and the performance of a network selection algorithm im- plementation is evaluated. The second theme is about challenges and problems of the standards and implementations used for the presented solutions. As the solutions andideas presentedin thisthesis wereimplemented andtheir perfor- mance evaluated, a number of challenges, modifications and configurations in the Android and Maemo frameworks and Linux operating system were found. Finally, the third theme addresses one possible path toward multihomed user equipments,wherenetworkaccessmayoccursimultaneouslyovermultiplenet- workinterfaces.
