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

Merge(Backgroundstream,ExtractPersons(Inputstream1), ExtractPersons(Inputstream2)) –Compatibility between the type of objects Information-Centric Service Enabler Network
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
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
