The
scope of this paper is to provide a detailed description of the
selected architecture and the functionalities considered for the AROMA
project. This project focuses on a heterogeneous radio access network
which includes several Radio Access Technologies (RAT) , namely; UMTS
Terrestrial Radio Access Network (UTRAN), GSM/EDGE Radio Access Network
(GERAN), and Wireless Local Area Network (WLAN). The corresponding
Common Core Network (CN) is considered to provide and satisfy different
kind of services, thus, different identified services have different
QoS, then, so the goal is to study and analyze some algorithms, that
best fit in the network in order to enable quality of service (QoS)
based on the service demand in the network. Radio Resource Management
(RRM) refers to a group of algorithms that are collectively responsible
for efficiently utilizing the radio resources within a RAT to provide
services with an acceptable level of QoS. Mainly, at present, Radio
Resource Management (RRM) algorithms are implemented independently in
each RAT. In the meanwhile, The Common RRM (CRRM) strategy, has been
proposed in the literature to coordinate radio resources utilization
among a number of RATs in an optimized way. This paper analyze CRRM
solutions with particular attention on implementations. Starting from an
analysis of the state of the art, the most interesting solutions have
been critically analyzed and then some in depth investigations on some
of the identified solutions have been performed.
