A novel mechanism for media resource control in SIP mobile networks

Research output: Contribution to conferencePaperpeer-review

Abstract

In UMTS Session Initiation Protocol (SIP) multimedia architecture, the service logic is located in the Application Servers (AS). AS may need to control bearer resources, for playing tones and announcements, for conferencing or for transcoding purposes. These bearer resources are located in a media server: the Media Resource Function (MRF) or Media Server. The interface between the AS and the MRF is currently not fully specified and does not allow offering the most basic services. This paper proposes a novel mechanism for the AS to control the MRF and allow complex media interactions. This mechanism is based on the use of VoiceXML to describe media scripts, on XML to report the results, and SIP INVITE and INFO messages to transport the interaction related information between the Application Server and the Media Resource Function.
