1. Status & Challenges Interoperability and global integration of communication infrastructure & service platform Fixed-mobile convergence to achieve a future Internet that is dominated by wireless devices and applications:  Heterogeneity of networks drastically increases  Every radio network is a potential access network to the Internet  Every handheld will become a mobile IP node  Mobility in all its dimensions (user, service, terminal) needs to be supported End-to-End Efficiency (E 3 ) Integrating Project of the EC 7 th Framework Programme E3 Technologies for Collaborative Cognitive RRM, Spectrum Management and Self-Organization ICT Mobile Summit 09.06 – 12.06 – Stockholm Outcomes of WP3 Enable autonomic networking by means of collaborative & autonomic interworking Implement Cognitive Radio & Self-x as key functions Boost End-to-End (inter-domain) QoS provision Rely on Cooperation of (mobile) peer and autonomous entities Approach 1) Emphasis on Self-X (RAN) Management  Semi-distributed (collaborative)‏  Distributed (autonomic)‏ 2) Boost of Cognitive System Control 1)2) Vision: to develop and provide technologies that achieve “Radio communication system efficiency through collaborating cognitive and self-organizing access network elements.” Radio Network Self-organisation  Enhanced performance and efficiency by cognitive, collaborative acting and self-organising network elements  Self-managed network complexity and heterogeneity: optimized, dynamic assignment of spectrum, radio and computational resources by reconfiguration and self-optimisation (e.g. Flexible, Cognitive multi RAT Base Station)  Resources adapted to actual environment and demands (terminal capabilities, resource usage, requested services and Quality of Service)  New management functionality: self-organisation on initiation, decision-making, control and optimisation  Highly automated process for self-optimisation of operational network parameters Spectrum Management  Motivation: bandwidth demand & heterogeneity of radio technologies  increasing flexible and efficient use of spectrum resources required   E 3 approach based on Flexible Spectrum Management (FSM) (E 2 R-II): DSA (Dynamic Spectrum Allocation), spectrum pooling and interference mitigation  Extension of concept and algorithms towards collaboration and co- operation of different access networks  Enhanced spectrum utilization efficiency by decoupling service provisioning from dedicated spectrum assignment Collaborative & Cognitive Radio Resource Management  Resource management with individual access brokers for appropriate assignment of local resources. This implements a collaborative RRM scheme where smart interpretation (cognitive) engines allow self-contained interpretation of exchanged information.  Semi-distributed RRM allocation, where resource management entities are extended to support one or more different radio access technologies. The access brokers have the cognisance to control exactly one admin domain.  Centralized approach for resource allocation where different administrative domains dispose of their own network management functionality but keep their proprietary backbone network and a unique resource management for each domain.
