Saulo VasconcellosJosé Ferreira de Rezende

Nowadays, mobile communications are an important slice of the telecommunications market. Users are looking for multimedia services and Internet access, needing service quality. This paper is a study of quality of service guarantees to mobile environments. A typical scenario, for internetworking mobile and fixed networks is presented, as well as its main challenges. Service classes concerned with mobility are suggested and a mapping from these classes to the IETF's quality of service model is carried through. Mechanisms intended to support the proposed classes are presented and simulated.
