Abstract
Due to the nature of wireless communications, a single radio access
technology (RAT) hardly satises all communication needs. RATs are roughly
divided into two types: cellular and short-range. It becomes increasing
popular to equip a mobile device with both types of air interfaces. By seam-
lessly integrating different types of air interfaces into a sin- gle network,
a new mobile communication model emerges. Benet from the mesh structure
interweaved by cellular and short-range links, the new model is able to enjoy
reliability, ¡exibility, coverage extension and enhanced service. Al- though
several architectures have been proposed based on this model, a practical
control solution for seamless integration of cellular and short-range systems
is still absent. We propose in this paper a novel cooperative architecture
with a control plane backed by cellular systems. A dedicated control unit is
developed to tightly control the user cooperation of mobile devices using
their short-range links. In addition to the architecture design, we propose
two services based on the proposed architecture. It shows the potential of the
architecture to carry new services, especially, multimedia services.
