Service Broker for Managing Feature Interactions in IP Multimedia Subsystem

Since the vast deployment of telecommunication services, until the broad development of innovative 3G services, dealing with Feature Interaction issue has been constantly challenging. This issue results in the occurrence of incorrect or unexpected behaviours from the features and services that are invoked during an IP multimedia session. The purpose of this article is to include a flexible SIP-based Feature Interaction Detection and Resolution algorithm in the service invocation mechanism of IMS. Through several feature interaction examples, we confirm that our proposed algorithm covers a wide range of Feature Interactions and manages the conflicts that arise between various features.
