8th International Conference on Feature Interactions in Telecommunications and Software Systems


About ICFI

The International Conference on Feature Interactions in Telecommunications and Software Systems (ICFI) has evolved out of the  Feature Interaction Workshop, which has been the primary international forum for discussion and reporting on research in the feature interaction problem in telecommunications and software systems since 1992. The forum includes:
  • Invited speakers
  • Presentation of research papers
  • Short presentations
  • Posters
  • Tool demonstrations
  • Excellent networking opportunities
ICFI'05 is the eighth in a series of international events addressing the issue of feature interactions. The seven previous ones were called workshops, but ICFI has renamed itself a conference reflecting the fact that it is the primary event in the field of feature interactions. The conference aims to bring together representatives of the telecommunications industry, the software industry, and the research community working on various aspects of feature interactions in order to discuss possible solutions and their practical applications, as well as setting directions for further research. Active debates will be encouraged; participants are invited to contribute topics for discussion. Poster presentations and tool demonstrations are also warmly welcomed. Original research papers are solicited, as well as brief reports on ongoing research and research already published elsewhere. 'Best paper' prizes will be awarded. As in the case of previous workshops in the series, the proceedings will be published in a book by a major international publisher.

The Feature Interaction problem

Feature interaction occurs when one feature modifies or subverts the operation of another one. This phenomenon is not unique to the domain of telecommunications systems: it can occur in any software system that is subject to changes (not to mention areas of medicine, engineering, and law that are not directly covered in this conference, but which may be taken into consideration in order to exploit useful analogies).

Although interactions among classical telephony features are now fairly well understood, the feature interaction problem presents new challenges in emerging types of systems based on policies, dynamic (Web) services, mobility, or new architectures such as Parlay, 3G, .NET, or GRID and active networks. The proliferation of players and software/service engineering techniques coupled with the constant pressure for the rapid introduction of new services and applications lead to undesirable interactions that jeopardize the quality of the products delivered as well as the satisfaction of the users. Detecting, solving, preventing, and managing such interactions at different stages of the development process are more than ever important problems that need to be addressed with cost-effective techniques and tools. Techniques successfully applied to conventional telecommunications systems are still useful in many cases, yet they may no longer be able to cope with the complexity of emerging systems.

We propose to focus the conference on the topics listed below. Contributions extending beyond this list and addressing other issues related to the interaction problem (e.g. classification, taxonomy or benchmarking) will also be welcome.


Technical papers will be published as the 8th book in the series on Feature Interactions in Telecommunication and Software Systems. Accepted papers must be presented at the conference by one of the authors. Technical papers submitted may be full papers or short papers.

Full papers. These must be unpublished and must not be submitted for publication elsewhere. Submissions of full papers should not exceed 16 pages.

Short papers. In order to make the conference as complete as possible from the point of view of coverage of current research in the area, we also solicit short papers. These can be industrial reports (I), position papers (P), or summaries of research already published elsewhere (S). Such papers should not exceed 5 pages but should be sufficiently self-contained to be appreciated on their own. Each paper should be clearly labelled as I, P, or S.  Industrial reports should describe industrial case studies or industrial research directions. Position papers should propose novel research directions. Summaries should contain appropriate citations.
All submissions must be in English.

The Feature Interaction Best Paper Awards

Two prizes will be awarded at the conference:

Most Novel Domain Award

This prize will be awarded to a high-quality paper that investigates feature interaction in the most novel domain of application. This mostly excludes areas emphasized in the past, such as (POTS) telephone systems. Examples of new areas are enumerated in the first item of the suggested topics list, but others are warmly welcomed.

Best Paper Award

This award will be selected by the programme committee based on the excellence of the paper.

Conference Location

 picture from the University Campus

The Conference is organised by the University of Leicester and the University of Birmingham, and will be located at the University of Leicester.

The University of Leicester (founded 1957) delivers high quality undergraduate, postgraduate and professional education and creates research that is of international significance. 70,000 people in 160 countries hold degrees and diplomas from the University of Leicester.

The Department of Computer Science has an international reputation for the excellence of its research in Algorithms & Complexity, Semantics, and Software Specification & Design.

Leicester lies at the heart of England close to major motorways, and a short distance from Nottingham East Midlands Airport. Leicester railway station is a ten minute walk to the University. The campus is compact - set within attractive green spaces. ICFI'05 will take place on campus.
