“…This allows optimizing the efficiency with no drawback on the results. This method does not emulate variations in the RS allowing measuring the effects of aged information [10] on both capacity/load and TSA abstractions. However, if TSA performs better for the evaluated scenario, aged information cannot reverse the situation, since it only adds a random deviation to the RS affecting both approaches similarly.…”

The Ambient Networks project aims at designing a future networking environment where today's networks (cellular, wireless and fixed) are seamlessly integrated offering a richer and smarter networking experience to applications and users. Main characteristics include dynamic composition and establishment of inter-network agreements, multi-access, multioperator and multi-hop operations, mobility and security support. Efficient resource management methods need to deal with the different characteristics of the heterogeneous access technologies: the access resources of each technology need to be abstracted up to a level of operation for resource management, this level being as much as possible technology independent. The work involves the definition of suitable resource abstractions, but also the definition of related algorithms for the respective abstraction layers and access selection modules. This paper presents two opposite methods for resource management in multi-access environments, contextualizing them on GSM specific access resources. Respective performance figures are then evaluated and compared through emulation.

“…In the following, we briefly describe the building blocks of MRM. For a more detailed description of MRM, we refer to [8,9]. Please note that these building blocks are common to all network-centric multi-radio management solutions and our further analysis is thus not limited to the MRM architecture.…”

Abstract. In this article, we present a multi-radio management (MRM) architecture for intelligent access selection and load balancing over multiple radio access technologies. We discuss possible implementations of this MRM architecture and analyze to what extent the IEEE 802.21 'Media Independent Handover' framework can be applied here. Starting from the fundamental building blocks of the multi-radio management architecture, we find several issues with respect to the integration with and the interworking between today's 3GPP and non-3GPP networks. Because support of 802.21 can largely differ from one access technology to another, we propose ways to compensate for these differences and finally present an adapted MRM architecture.

“…We determine the signaling requirements of a largely centralized and a completely distributed resource management scheme of a multi-RAT system at the example of the so-called Multi-Radio Management (MRM) concept [2]. The distributed deployment alternative is preferred by 3GPP standardization, given that it does not require new network elements and it respects the functional split between radio-specific functions in the access and radio-agnostic functions in the core network.…”

Increasing bandwidth demand from mobile Internet applications and the existence of 2G, 3G and soon 4G equipment in operators' networks forces them to implement an efficient resource management over all available radio access technologies. While such a multi-radio management will certainly improve resource utilization and allows reducing local hot spots, it comes at the cost of additional signaling load. In this work, we present an analysis of the signaling requirements of a multi-radio management in the fixed part of an operator's network. The signaling load for multi-radio access selection in different system architectures and for different signaling concepts is evaluated, quantified and compared. This analysis permits to conclude on the best-suited implementation strategy for co-located GSM, UMTS and LTE networks.
