“…Thus, although multiple proposals have shown increased benefits of spectrum and network usage [9,16,18], they cannot be directly used in a multiple technology environment. Layer 3 protocols are required for this environment, and in particular IP-based protocols.…”

“…4.2 is still applied by the Mobile Node. However, now the network also can move target Mobile Nodes each time a timer expires (corresponding to an optimization run in many RRM proposals [9,16,18]). Mobile Nodes reallocation can be potentially implemented according to more complex or simple algorithms.…”

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.

“…The distribution of functionality between network domains of different network operators can be based on pre-established business agreements (e.g., roaming agreements) or establishing dynamic cooperation agreements based on network composition [10,16,44,45]. The distribution of multi-access functionality in different networking scenarios has been discussed for example in [46][47][48][49].…”

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 schemes between access providers providing different types of access connectivity. As a result, a variety of access technologies will be available for users at the same time. In this article we present an architecture and a framework capable of integrating different access systems into a multi-access system and selecting the best suited access for users. A utilitybased approach is proposed for the evaluation of different access allocation choices, which is based on user and network policies, the performance of access bearers, and the availability of access resources. We present a general multi-access management framework, which integrates the different multi-access related functions: access detection, access evaluation and access selection, which can then lead to an access handover.

“…This is the idea of inter-system optimization addressed by joint (or common, or multi-access) Radio Resource Management (RRM) schemes [9]. What is defined by joint RRM (JRRM) is a set of algorithms usually running on a centralized network entity that take decisions on the optimal access network selection or the reallocation of resources between different wireless access networks.…”

Efficient coordination and management of radio resources in heterogeneous wireless networks is a key requirement for the realization of the Beyond 3G vision. In this context, radio resource optimization algorithms as well as infrastructures that allow for their performance evaluation are of great value. Towards these directions, the goal of the paper is twofold: first to present a testbed that enables integration of geographically distributed modules simulating different radio access technologies with independent realizations of inter-system optimization functions, and second to present the integration of an algorithm for admission control in IEEE 802.11 networks into the described platform. The algorithm, which is based on the notion of Effective Capacity and provides statistical overflow probability-related QoS guarantees, is validated using both a simulator in a stand-alone fashion and a simulator attached to the presented testbed. The integration of the algorithm on the testbed validates the testbed's capability to serve as a facility for optimization studies in simulated composite radio networks.
