The concept of network controlled handovers is commonly used in cellular technologies. With multi-mode terminals, using layer-2 techniques, this concept can only be applied inside each technology, which impairs the full exploitation of multi-access support. We discuss a layer-3 technique able to operate across technologies, and present an analysis of the performance advantages this technique brings. In general, an increase around 25% in system usage is achievable. The paper further analyses some cell characteristics that impact on the performance improvements achievable by network controlled handovers.
