Vertical handover policies for common radio resource management

The 3G and Beyond 3G wireless networks introduce new technologies, and in many cases, new frequency bands. Integrated hierarchical network architectural studies suggest that by using a Common Radio Resource Manager to engineer traffic across these component networks, operators can achieve increased efficiency and flexibility in supporting changing traffic demands. This study demonstrates how vertical handovers can be used to optimize network performance, by adaptively rearranging traffic across network boundaries. We survey policy implementations that consider which services/sessions shall move, where they shall move, when they shall move, and whether they shall return.
