The roaming services with the predefined security associations among the entities in various networks are especially complex. We propose a novel architecture to support future context-aware interoperator roaming services throughout 4G networks by using Roaming Coordinators. We design a secure context management model for the practical use of Smart Cards in the secure roaming services. Our architecture solves the interoperator roaming management problems while minimizing the processing overhead on the mobile nodes.
