RESUMO

Fourth Generation Networks (4G) introduce the capability of ubiquitous access to services in heterogeneous networks. In these environments, the distribution of the management would require semantics for common sharing vocabulary, an ability which is not yet provided. For that reason, service providers from different management domains are facing the challenge of exchanging managerial information between them during handovers. This is mainly due to the lack of new business models with access control, peering agreements, billing, security and privacy management, QoS standardization which strongly limit the collaboration between providers in the moment of receiving a new user. This work describes a set of ontologies to be used by new access models supported by ontologies for 4G. The ontologies are mapping out the common vocabulary of entities. The approach used to validate the set of ontologies was the development of two service prototypes for 4G, the prototypes specialized a subset of Haggle, Y-Comm, SOHand and DOHand ontologies. The main contribution is to provide the information structuring necessary for easy exchanging of managerial information between service providers, users and brokers. Another contribution of this work is to demostrate how ontologies facilitate the creation of new services in integrated environments
