High level services and data transport service provision are facing important advancements towards a more flexible business models and Internet services with the internetworking of several complementary access technologies using IP. This imposes new requirement in users' mobile terminal, such as intelligent discovery and selection of access networks, vertical handover support and roaming. The result of such integration of networks, also known as "4th Generation Networks", will require that transport network and user's terminal coordinates for providing of a "persistent" transport service. This paper presents the conceptual high level description of a context-based management distributed service and profiling system based in OWL, the W3C ontology language, in order to provide this persistent transport for mobile user's data in a heterogeneous environment of IP-based network.
