This Recommendation describes the concept and high-level architectural model of object-to-object communication for ubiquitous networking in next generation networks (NGNs). It also presents requirements and a mechanism for identification of all objects and for providing connectivity to them. This Recommendation covers the following items: General overview of ubiquitous networking in NGNs from the end-user perspective Basic concept and high-level architectural model for object-to-object communication using NGNs Requirements and technical considerations of object-to-object communication for ubiquitous networking A mechanism for object-to-object communication.
