Information for handover management in heterogeneous networks: data representation,languages and integrated platforms

Due to the convergence of radio, television, telephony and Internet areas, the mobility of users, the ubiquity of services, and the development of new technologies to unify access provision, the interaction between providers and users will be required for access on demand in heterogeneous environments. This interaction should allow, in addition to seamless handovers, the negotiation based on technical requirements and user's desires during handover decision processes. The central part of the information being exchanged between the access provider's attachment points and user's devices should be a uniform and common structure that models the handover management information, in terms of what the information represents their semantic meanings and relationships. This work presents a set of ontologies, for this purpose, employed during handover decision processes, in integrated networking platforms for access on demand. A case study is presented, which demonstrates how a service could be integrated in two different platforms for such environment.
