built on three major innovations: • • • The concept of a single, universal type of networking entity, the Ambient Network (AN) Consequently, a single universal networking reference point, the Ambient Network Interface (ANI) A set of naming and identification capabilities, independent of the underlying infrastructure Ambient Network Ambient ANI Exchange of messages 21-06-0762-00-0000 Network An

Security Connectivity Controller Multiaccess Ambient Resource Interface Ambient Network Interface Phase 2 Project Structure 21-06-0762-00-0000 Areas relevant to IEEE 802.21 • WP-B: mobility management • Has developed advanced trigger delivery and processing functionality • Supports filtering, aggregation and delivery of triggers • Users can request triggers they are interested in, and also provide clues as to how they should be processed • WP-D: Context, Policy and Network Management • Is investigating information bases to support AN functionality • Part of this includes information to support handover decisions • Concept of an Ambient Network Information Service • The triggering functionality is considered as a “context provider” 21-06-0762-00-0000 The Ambient Network Information Service Infrastructure “clunky” “simple” voice service handover SIP, IMS (between devices) data service MIP (same device) IP L3 L2 GSM handover today Timeline WiFi B’tooth 3G “enhanced” data service handover RR-Mgmt Cost QoS WiMAX supported service Sec Capab WiFi what info means to support it Perf dynamic IEs Sec 3G 21-06-0762-00-0000 3G Cost WiFi ANISI 802.21 QoS Timeline WiMAX “effective” data service handover How AN plans to achieve the objective • More dynamic IEs need appropriate infrastructure support for information management • Ambient Networks Information Service Infrastructure • distributed database with optimised data dissemination algorithms • • dynamic trigger management • • allows for fast and personalised notification of trigger changes aggregation of information • • allows for fast retrieval and fast update of dynamic information allows for service specific IEs (i.e. is this network currently good for this service?) as well as for traffic reduction and flexibility security and access control to IEs • allows phased disclosure of knowledge as authentication steps take place (i.e. L2 attach – access to limited knowledge, L3 attach – access to more detailed knowledge) 21-06-0762-00-0000 Focus on ANISI – the Ambient Networks Information Service Infrastructure sink • Distributed storage capability – two-tiered to address scalability, ability to cross administrative domains (AN feature), secured for access control • Inclusive of pre-processing components – Carry out data fusion for common purposes – Carry out data translation to address diverse nature of managed information as well as migration – Carry out filtered trigger notification 21-06-0762-00-0000 src DHT lookups P2P exchange of info What advantages does it bring • To the end-user • ability to make more intelligent and efficient (handover) decisions based on current context for surrounding networks • opportunity to use more innovative services that seamlessly “survive” over heterogeneous networks • in the event of component failure, available knowledge allows the user to infer what went wrong • To the network operator • more accurate monitoring of resource usage • opportunity for corrective actions to balance resource usage and customer satisfaction 21-06-0762-00-0000 Conclusions in a Nutshell Ambient Networks contribution AN Triggers Link Layer Triggers State Change

Services Network context More innovative services for the user Optimised usage of resources for operators Next Steps • Ambient Networks has a number of concepts and ideas that we would like to bring to IEEE 802.21 for comment or inclusion in your standard • How should this proceed? • Need to work together to identify exactly where AN concepts provide value to IEEE 802.21 • What are IEEE 802.21 plans beyond finalisation of first draft? 21-06-0762-00-0000
