In this paper we propose a control method for access network resource sharing between SIP users involved in a multi-media session. We propose a communication model in which a SIP control entity controls the end-to-end QoS negotiation procedure between the users, and blocks the session setup if there are not enough resources in the access networks for the required QoS. Moreover the proposed method allows the SIP control entities to inform users about the amount of available resources in the access networks. This control method has been developed on the basis of the end-to-end negotiation model proposed in the “Integration of Resource Management and Session Initiation Protocol” RFC, and bearing in mind the QoS classes and parameters defined within the ETSI TIPHON project for VoIP systems.

Abstract

In this paper we propose a control method for access network resource sharing between SIP users involved in a multi-media session. We propose a communication model in which a SIP control entity controls the end-to-end QoS negotiation procedure between the users, and blocks the session setup if there are not enough resources in the access networks for the required QoS. Moreover the proposed method allows the SIP control entities to inform users about the amount of available resources in the access networks. This control method has been developed on the basis of the end-to-end negotiation model proposed in the “Integration of Resource Management and Session Initiation Protocol” RFC, and bearing in mind the QoS classes and parameters defined within the ETSI TIPHON project for VoIP systems.
