ABSTRACT
The challenges presented by the convergence are being addressed to facilitate the successful implementation of new mobile technologies. Each network has been enhanced to provide related services, voice or data. Web data services have been integrated into 2G cellular networks with the introduction of the General Packet Radio Service, GPRS, and voice communications are now transported over IP networks using Voice-Over-IP encapsulation. These adapted data and voice services build the initial bridge between cellular and IP networks and deploy new technology layers for each respective network. IP and cellular networks differ fundamentally in infrastructure, communication protocols, and properties and their convergence has
become a technical research challenge. Designing hybrid cellular and IP access in integrated 3G and IP networks is the focus of this chapter.
