QoS has been a widely explored area of research in recent years. A remaining problem in this area is to create a service model which is easy to use for application programmers or service users. This is an important problem since an overly complex service model with too many QoS parameters to configure is likely not accepted by a user or deployed by a service provider. In wireless mobile networks, this problem becomes even more complex since, for example, the occurance of handofFs render the deployment of QoS more difficult. This paper proposes a service model especially suited for wireless mobile networks. The service model is derived from the currently discussed Differentiated Services approach.
