2. 2 Mobile data traffic is increasing faster than revenues –Mobile telephony was easy because revenues scaled with traffic Differentiation with value added services (VAS) –Imode success story Value added services composed by different service enablers within the operator network –Similar to mashup web-services Offloading service processing from terminal to network –Reduce battery consumption –Avoid terminal incompatibility problems Locate processing close to the user –Interactive services more sensitive than static content –Users are mobile, roaming in foreign networks Background

4. Copyright © 2010 DOCOMO Communications Laboratories Europe GmbH 4 Improved quality of experience to the user –reduced latency More efficient operation of the core network and servers –reduce unnecessary traffic –minimize server energy consumption Enable new services –not possible or very hard to provide with current technology Goals

6. Copyright © 2010 DOCOMO Communications Laboratories Europe GmbH 6 Some ICN mechanisms are applicable –Name-based resolution/routing Service components as objects –Can be both data and services (programs) –Analogous to object oriented programming New issues –Both caching and processing nodes needed in the network –Requirements on execution environment Interconnection of service components and data –Service composition nodes configuring a service or autonomic composition New Issues –Service objects may take (several) input arguments E.g. Merge(Backgroundstream,ExtractPersons(Inputstream1), ExtractPersons(Inputstream2)) –Compatibility between the type of objects Information-Centric Service Enabler Network

7. Copyright © 2010 DOCOMO Communications Laboratories Europe GmbH 7 Placement of service components –Placement based on storage, bandwidth and processing –Interconnection of multiple components Mobility –Both the users and objects may move –Maintain connections during mobility Security –Protection of data and software –Protection from malicious code Information-Centric Service Enabler Network

8. Copyright © 2010 DOCOMO Communications Laboratories Europe GmbH 8 Controlled environment –Security and QoS available –Integration with billing etc. Roaming agreements –Moving services between operators essential –Deployment with partial support Centralized or decentralized implementation Deployment in a Mobile Operator Network
