A Framework of Community Management with Object Deputy Mechanism for IP Multimedia Subsystem

This paper presents an approach to the problem of community data management in the IP multimedia subsystem (IMS) environment. More specifically, it describes a framework of the community management with the use of object deputy data model, which is developed as a key component of the enhanced platform for IMS to provide group-centric, media-rich interactive services. Furthermore, on the basis of data management paradigm over hybrid peer-to-peer (P2P) network combined with the IMS architecture, we consider binding a database capability for the community management with each super-peer on the network. In addition, we introduce the concept of "public community identity" to identify each community on the IMS network and route a SIP request addressed to a specific community based on a set of filter criteria included in the user/service profile.
