| The Intelligent Network (IN) allows rapid changes in the
services provisioned and their functionality. Services may be supplied
by different service providers, making it unlikely that all service specifications
will be available for examination by any single agency. Approaches
to handle feature interaction problems must be able to operate within these
constraints. Work by the authors has produced a generic run-time
feature interaction manager (FIM) concept to manage feature interactions
in a live network. It monitors features as black-boxes, learns their
"correct" behaviour and uses this to determine when feature interactions
have occurred.
This paper describes and compares experiences using three different techniques to realise the proposed approach. These are: states sequence monitoring, artificial neural networks (ANN), and rule-based monitoring which also includes integrated generic resolution approaches. The paper explores the design alternatives with the various techniques, and reports on the results obtained from experimentation.
