Abstract:

In this paper，the concept of Internet of things and sensor network are briefly illustrated，as well as the key technologies which support Internet of things. Differing from existing isolated sensor network，the future sensor network interworks with the telecommunication networks to support various convergent applications.This kind of convergence brings supplementary requirements to the telecommunication network，such as network management，service management and location management. Additionally， approaches of telecom and sensor network convergence are demonstrated at the end of the paper.

Key words: Internet of things, IPv6, sensor node, convergency
