Diss.
Thisthesisconcentratesonaccessnetworkselectionandmobilitymanagementin
a heterogeneous network environment. 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. Themainmotivationforthisistheperformanceevaluationfrom
