A personal communication service creation model for Internet-basedunified communication systems

摘要

Advances in the Internet and telecommunications technologies havespurred many research efforts in Internet-based unified communicationsystems, which integrate heterogeneous devices and networks (PSTN,cellular networks, or the pager networks). Nonetheless, these systemslack support for a systematic, easy, flexible way of customizing andcreating services at the system level as well as at the user level. Inthis paper, we present such a service creation model by exposing alimited set of primitives from a call model that is network and deviceindependent. Our model and framework not only supports the traditionaltelephony call services easily but also enables novel ways of creatingthird party services such as application-specific billing services
