Abstract. This paper presents an online detection and resolution method for feature interactions among integrated services in home network systems. To achieve reasonable online detection and resolution, we introduce three new concepts in this paper. Specifically, (a) activation which explicitly defines the execution lifetime of services, (b) mandatory methods which guarantees essential and optional operations in services, and (c) suspend/resume mechanism which allows lower-priority services to sleep temporarily and to wake up later when all conflicting services are terminated. A case study demonstrates the effectiveness of the proposed method. Keywords. home network system, online resolution, activation, mandatory methods, suspend/resume mechanism
