Recommendation ITU-T Y.4404/Y.2062

Framework of object-to-object communication for ubiquitous
networking in next generation networks

1 Scope
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.

3 Definitions

3.1 Terms defined elsewhere
This Recommendation uses the following terms defined elsewhere:

3.1.1 context [ITU-T Y.2002]: The information that can be used to characterize the environment
of a user.
NOTE – Context information may include where the user is, what resources (devices, access points, noise
level, bandwidth, etc.) are near the user, at what time the user is moving, interaction history between person
and objects, etc. According to specific applications, context information can be updated.
