DA, BA, MA: Evaluating extendable IMS/SIP (VoIP) Client Libraries, Components and Applications with Focus on Registration, Presence and Location -- in cooperation: CDTM, Georgia Institute of Technology, Deutsche Telekom Laboratories

10.12.2009, Abschlussarbeiten, Bachelor- und Masterarbeiten

The goal of this research project is to generate an overview of available IMS/SIP client libraries, components and applications, install and deploy them and evaluate them using defined criteria focusing on IMS application features like Authentication, Presence, Location, Multimedia, etc. The clients should be tested and evaluated on devices (mobile phones, laptops, etc) provided by the CDTM using the CDTM owned and maintained Open IMS Core system running in the IMS ResearchLAB.

Problem Description:
A lot of research work was conducted in the area of server side IP Multimedia Subsystem specifications and proposals and many commercial and some Open Source IMS systems are available to build an IP based multimedia system in carrier grade quality.
Due to that many carriers like Vodafone, Deutsche Telekom, O2, A1, etc are moving forward with implementing IMS as their main and soon only core network technology. So soon, all media traffic on a fixed and mobile network will be transmitted and signaled using IMS – which means IP and SIP.
In contrast to the huge amount of effort that was made to develop server side IMS, there is a major lack of clients for end-user devices in general. IMS promises new applications for mobile phones, fixed phones, IPTVs and computers, but so far only a few client libraries, components and applications are available to deliver these applications. Most of these clients are not mature enough to provide all means to develop appealing IMS applications or are not IMS specification compliant at all.

Goal of Research
The goal of this research project is to generate an overview of available IMS/SIP client libraries, components and applications, install and deploy them and evaluate them using defined criteria focusing on IMS application features like Authentication, Presence, Location, Multimedia, etc.

The clients should be tested and evaluated on devices (mobile phones, laptops, etc) provided by the CDTM using the CDTM owned and maintained Open IMS Core system running in the IMS ResearchLAB. (https://wiki.cdtm.de/Research/ResearchLAB)

Approach:
- Get familiar with the SIP protocol specific parts of the IMS specification
- Get familiar with the CDTM ResearchLAB IMS Core system and interfaces
- Develop a client evaluation concept and criteria structure
- Create an overview about the current state of the art and availability of client libraries, components and applications
- Deploy clients on devices
- Test and evaluate clients using the CDTM ResearchLAB IMS Core
Preparation:
- 3G/4G Telecom - http://de.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System
- IP Multimedia Subsystem - http://de.wikipedia.org/wiki/IP_Multimedia_Subsystem
- Session Initiation Protocol (SIP) - http://de.wikipedia.org/wiki/Session_Initiation_Protocol
- Understand SIP/IMS network architecture and protocol.
