Presence service middleware architecture for NGN

Presence services allow individuals to interact with other people and to participate in new business opportunities such as on-line gaming, address book service, public chat, etc. Hence, we currently see an increased interest from presence service developers and providers in NGN. In this paper we propose a distributed service architecture and middleware platform to cope with the problems such as service provisioning, QoS, bandwidth provisioning which comes from distributed service architecture. This allows the presence services to utilize the features and capabilities that are inherent to the NGN. At the same time existing various interactive services can be flexibly adapted to this new type of network
