Mobile Service Platforms

• Mobile network coexistence– Circuit switched IN, CAMEL– Packet switched IMS

• Emerge of packet based services• Emerge of packet based services– 1st phase (push-to-talk) with limited success– Cost reduction drives All IP Network

• Packet-based service control platform for all services: IMSO t diff ti ti th h i bl t • Operator differentiation through service enablers to for a service delivery platform (Application Servers)– Content handlingg– Session mobility, Roaming– Subscriber and device management

Advanced Mobile Service Platform: SPICE

• SPICE (Service Platform for Innovative Communication Environment)– IST-FP6 Integrated Project (part of Wireless World Initiative)– Coordinator: France Telecom– Duration: 01/2006 – 06/2008 (30 months)/ / ( )– Budget: 22 M€

i i d d l l d• Vision: to design, develop, evaluate and prototype an extendable overlay architecture and framework that supports– Easy and quick service creation of intelligent and ambient-aware services– Cooperation of multiple heterogeneous execution environments– Pan-European seamless delivery of services across operator domains,

networks and terminals

• Consortium composition: 23 partners– 6 operators, 7 manufacturers, 7 Research Centers / Universities, 2 SMEs– 1 consultancy company

Key achievements of SPICE

• Service Delivery Platform Architecture linking to IMS and embedding a knowledge layer

• Component-based middleware layer ensuring the inter-working of distributed service components

– Semantic publication and discovery

– Service broker

– Service roaming manager

• Advanced semantically-enhanced service creation and composition tools and composition tools

• Distributed Communication Sphere Management system (Dynamic Desktop, multimodal delivery,…)y ( y p, y, )

• Access control framework

• Development of a set of Intelligent service enablers

Service Roaming in SPICE

Service roaming would allow a user to have access to his/her subscribed services or composite services regardless of the administrative domains or countries with a foreign operator new value added services

Outlook

Outlook: Distributed Service Platform

• Distributed IMS P2PSIP • Distributed IMS, P2PSIP scalable, cost reduction

• Example: femtocell-based distributed service platform "P-Gate"


Concepts

Distributed Service Platform• Physically distribute intelligencey y g• Move part of the service logic to network edges• Offload central servers

h h h lf d d l bl• Enhance services through self-organized and scalable capabilities in the network/at the edges (e.g., storage, proxy)

• Allow peer-to-peer service provisioning for low revenue (flat rate) services, e.g., best effort voice (Skype!)(Skype!)

• Differentiated controllability, availability, reliability and performance and coupling with operator infrastructure

• Opening up enablers to third parties profit from 3rd

party overlay applications


Outlook: distributed service platform
