The emerging 3 rd generation services are provided through various types of networks and terminals. Roaming users rely on new kinds of wireless networks and terminals to offer mobility and make services available everywhere. The users' requirement for continuous access to personalized services from any place, transparently and independently of the underlying network technology and the terminal or point of access, was satisfied by the first VHE prototypes. The challenge in service engineering is now to make these services smarter by adding context management capabilities to them. In this paper we propose an enhanced framework for efficient context management in a VHE environment.

Abstract:This paper deals with the QoS management issue utilizing the active network technology. The disadvantages of the centralized network management are presented and the current solutions for distributed network management are discussed. The proposed architecture focuses on the QoS management for DiffServ architecture. The improvements that our architecture offers are presented through a service example, which involves QoS configurations.
