The Internet of things is a new generation information network which realizes machine-to-machine communication. In view of the fact that people need the mobility of the Internet of things, the integration scheme of TD-SCDMA network and the Internet of things is designed. 3G TD-SCDMA network is used as the basic network of transmitting information of the Internet of things. At the same time, TD-SCDMA mobile terminal is integrated with RFID reader. TD-SCDMA networks can provide high-bandwidth and high-speed information transmission channel for the Internet of things. TD-SCDMA mobile terminal can realize the mobility of the access part for the Internet of things. Additionally, the network element functions of the mobile Internet of things are described. In order to realize the information exchange between TD-SCDMA network and the Internet of things, the communication protocols of the mobile Internet of things are discussed and designed in detail. Finally, the network performance which is gotten by using OPNET software shows the mobile Internet of things based on TDSCDMA network can be realized by adopting the rational network design and the effective communication protocols.
