Device discovery in future service platforms through SIP

Yuan Chen, Suparna De, Ralf Kernchen, Klaus Moessner
2012 2012 IEEE Vehicular Technology Conference (VTC Fall)  
The validation of the proposed extensions is shown through an Android SIP client application that acts as a device browser and recommender for different multimedia services to users.  ...  This paper proposes an extension to Session Initiation Protocol (SIP) for contextualized service delivery in a service delivery platform (SDP) that enables device specific multimedia delivery.  ...  SIP, as defined in RFC 3261, [3] is a control protocol on application layer. SIP itself does not provide any services, being only involved in the signaling portion of a communication session.  ...

The Session Initiation Protocol: Internet-centric signaling

H. Schulzrinne, J. Rosenberg
2000 IEEE Communications Magazine  
The Session Initiation Protocol provides advanced signaling and control functionality for a wide variety of multimedia services.  ...  It can find use in applications ranging from Internet telephony and conferencing to instant messaging, event notification, and the control of networked devices.  ...  The request URI in a SIP request is typically a SIP URI, but could also be a tel: URL identifying a traditional telephone number.  ...

A stepwise approach to developing languages for SIP telephony service creation

Nicolas Palix, Charles Consel, Laurent Réveillère, Julia Lawall
2007 Proceedings of the 1st international conference on Principles, systems and applications of IP telecommunications - IPTComm '07  
Developing a SIP-based telephony service requires a programmer to have expertise in telephony rules and constraints, the SIP protocol, distributed systems, and a SIP API, which is often large and complex  ...  This approach enables critical properties of services to be guaranteed and captures expertise on the operational behavior of a service.  ...  For example, the SIP request INVITE either initiates a dialog or, if used in the context of an existing dialog, modifies dialog characteristics.  ...

Supporting mobility in an IMS-based P2P IPTV service: A proactive context transfer mechanism

Ivan Vidal, Jaime Garcia-Reinoso, Antonio de la Oliva, Alex Bikfalvi, Ignacio Soto
2010 Computer Communications  
In this context, standardization bodies, such as ETSI and ITU-T, are specifying the architecture of IPTV systems based on IP multicast.  ...  One of these involves the service handover when the user moves to a different network.  ...  The latter consists of updating the IPsec related information and the URI of the P-CSCF for future SIP requests.  ...

Toward Testing Security Attacks and Defense Mechanisms for P2PSIP in MANETs with a Simulator

Alexandre Cormier, François Gagnon, Babak Esfandiari, Thomas Kunz
2017 Proceedings of the 14th International Joint Conference on e-Business and Telecommunications  
The Session Initiation Protocol (SIP) is a standard for session establishment in Voice over IP context, notably, but is not adapted to MANETs and peer-to-peer (P2P) networks.  ...  Mobile Ad hoc NETworks (MANETs) are comprised of mobile devices communicating with each other over multi-hop wireless links.  ...  (Seedorf, 2006) proposes the use of self-certifying SIP URIs to protect the integrity of registrations.  ...

2006 2006 IEEE International Conference on Communications  
SPL and SIP-SLEE have been implemented and they are now being used to develop and deploy real services, demonstrating the practical benefits of our approach. • What is the service programmer community  ...  SPL relies on a Service Logic Execution Environment for SIP (SIP-SLEE) that introduces a design framework for service development based around the notion of session.  ...  For example, the SIP request INVITE either initiates a dialog or, if used in the context of an existing dialog, modifies dialog characteristics.  ...

A VoIP Privacy Mechanism and its Application in VoIP Peering for Voice Service Provider Topology and Identity Hiding [article]

Charles Shen, Henning Schulzrinne
2008 arXiv   pre-print
A number of existing documents on VoIP privacy exist, but most of them focus on end user privacy.  ...  We also show a case study on how VSPs can use this mechanism for identity and topology hiding in VoIP peering.  ...  In fact, all these header fields may contain SIP URI, which is commonly formed by a user part and a service provider part. SIP also allows the use of other URI formats.  ...
