Adaptability for flexible mobile service provision

in 3G and beyond

Generic adaptation mechanisms Generic, re-usable, run-time updatable adaptation engine Generic indicates independence from:

Types of context parametersAdaptation algorithms

Re-usable for adaptation decisions across different functional

layer Updatable at run-time -> inline with 4G requirements Already available: Development of core functionality,

integration with MOBIVAS platform, implementation of certain

adapters Further steps:

Development of remote algorithm loading function (Java, network

programming)Generic interface for context retrieval/update (Java, network

programming)Development of further adapters (Java, RDF/XML)

Service adaptation

Many possible adaptation functions• (Re)allocation of service components• Composite services (multiple components)• Dynamic interactions with other components

Many possible approaches• Deployment-time vs. run-time• Application-aware vs. application transparent

Many possible service “models”• Java, Web services,…

Further steps:• Deployment-time component allocation (Java, UML)• Run-time component re-allocation (Java, UML)• Independence from service model and representation (Java, UML.

- Efficient utilization of the wireless link

- Dynamic, on-demand composition

- Support for multiple service models/representations

Support for automated deployment of OSA/Parlay services

Applications may use (in a secure manner) functionality of the underlying infrastructure through open APIs (e.g,. OSA/Parlay)

Registration/deployment of those applications introduces significant management overhead

Mediating service platform simplifies this procedure – easier deployment for VASPs

Already developed: basic functionality + OSA/Parlay emulator Further steps

• Integration with service profile manipulation/storage functions (RDF/XML, JDBC)

• Enhancement of GUI (Java)• Generic service validation functionality (Java, UML, XML)• Contract management and monitoring (Java, UML, XML)
