Abstract:

M2M application construction is an effective road to build ubiquitous network. The key point of ubiquitous network construction is the network infrastructure construction.Telecommunication operators are main forces of it.To play a more important role of ubiquitous network construction，operators should build more robust backbone network，industry public network，gateways of private network and general service systems. By the development of M2M service，operators can accumulation of experience， explore all kinds of construction models，and finally form ubiquitous network infrastructure construction solution.

Key words: M2M, ubiquitous network, telecommunication operator, network infrastructure, private network, industry network, backbone network
