With the opening of the telecommunication market and the emergence of low-cost and heterogeneous wireless access technologies, it is envisaged that next-generation network and service providers will not only vary in the deployed access technology but also in their business models and structures. Such providers will differ from large providers such as the current telecom providers offering multiple services and covering large geographical areas, down to small providers offering certain services such as conferencing or messaging only or covering small geographical areas such as a coffee shop or a shopping mall. Further, while in the current networking environment, a home provider of a user is usually represented by a large telecom provider; in such a heterogeneous environment, any trustworthy entity such as an application provider, a banking entity, or a credit card provider that is capable of authenticating the user and marinating his usage profile can act as a home provider. Towards this vision this article discusses the issues that concern the establishment of multimedia applications across heterogeneous networks.
