Summary

Recommendation ITU-T Y.4455 introduces Internet of things (IoT) network capability exposure (NCE). The IoT NCE is a functional entity in network domain, and facilitates IoT applications and services to make full use of capabilities of their underlying networks. The IoT NCE can optimize user experience, improve network efficiency and expose network capability in order to optimize IoT applications and services.

Recommendation ITU-T Y.4455 clarifies the concept of the IoT NCE, identifies its general characteristics and common requirements, and provides the reference architecture and relevant capabilities for the IoT NCE. Additionally, it provides several use cases and common procedures to illustrate the concept and the architecture of the IoT NCE.
