Evaluation of User-centric Performances to Select an Optimal Access Network in Heterogeneous Systems

摘要

In recent years, wide varieties of wireless access networks supporting multimedia services are emerging with different characteristics. The service areas of many of these networks are overlapping so that a mobile user from an overlapped service area can access any network that supports the user application. A mobile user can take advantages of the availability of such heterogeneous multimedia networks only when the user terminal is equipped with a mechanism that can select an optimal network for the application. In this report, we present an analytical framework of such a network selection mechanism and discuss its implementation issues.
