The arrival of fourth generation mobile networks, based on IP core networks, lead us to the development of certain services, such as: Quality of service, mobility and AAA. This paper proposes architecture to supply quality of service support based in the differentiated services technique, known as Diffserv. In the same way we analyze the main components of this architecture: QoS Broker (central policy broker of quality of service, whose goal is the appropriate configuration of the routers in the network), Access Router (in charge of the management of the queuing system in order to provide QoS) and the AAA server (management of QoS user profiles).
