Mobile Ontology: Towards a Standardized Semantic Model for the Mobile Domain

Ontologies will be crucial for the future development of Next Generation Service Delivery Platforms. While various projects have defined ontologies for the mobile domain, there is yet little agreement on a common semantic model. One reason is the intrinsically hard problem of finding, using, mapping and evolving already existing ontologies. In this paper we present the Mobile Ontology, an effort within the IST project SPICE to converge towards a standardized ontology. Our approach is based on a minimal core ontology that defines common concepts for sub-ontologies of relevant domains and that is easily extensible towards existing and future ontologies. It is our intention to make this ontology available to other projects and collaboratively work on standardized ontology for the mobile domain.

Towards service awareness and autonomic features in a SIP-Enabled network

Next-generation communication infrastructures can become autonomic only if they can leverage some form of awareness about themselves and the services they deliver. Such awareness can be reached by disseminating across the network a proper amount of multi-faceted knowledge. We have started to identify a set of basic capabilities that provide a degree of service-awareness and enable various autonomic behaviors, oriented towards sustaining communication services within a SIP-enabled network. We have designed network features that support those capabilities, in particular focusing on awareness features relevant to service deployment, monitoring and exposition, and we have built those features natively into the control plane, relying upon the SIP Event Framework specifications. We have also defined a set of scenarios that exploit the service awareness introduced in the network for various autonomic purposes.
