Heterogeneous wireless networks where several systems with different bands coexist for
multimedia service are currently in service and will be widely adopted to support various …

Embodiments of the invention relate to cellular wireless net works and are particularly Suited
to networks including dif ferent types of base stations. So-called femtocell base stations are …

Communication networks and mobile devices integrate an increasing number of access
technologies. At the same time, new business roles emerge, which lead to new cooperation …

This letter studies the problem of maximizing the spectral efficiency for multi-radio access
(MRA) with a limited transmission power constraint in cognitive heterogeneous networks …

A novel analytical framework of multiple radio access technologies (Multi-RAT)
communication system is proposed where a small cell serves K mobile users via IEEE …

Nesta dissertação é introduzida a seleção de acesso no contexto de gerenciamento de
recursos em ambientes sem fio. O objetivo é utilizar o algoritmo genético como ferramenta …

In the ambient networks project research is ongoing in order to define a new control space
for future internetworking. This internetworking will be characterized by a high degree of …

Integration of heterogeneous access technologies to provide multi-radio access allows for
dynamic access selection. The" always best connected" paradigm can increase system …

In this paper, we investigate the capacity gain of access selection in a multi‐radio access
network with heterogeneous radio access technologies (RATs). We classify the kinds of gain …

In this paper we present three context transfer mechanisms to support seamless (inter-
system) handover: L2 tunnel, SDU reconstruction and SDU context transfer. The hand-over …
