On November 25, 2017, China Mobile released CCMP version 3.0, the world”s largest independently developed IoT connection management platform. This platform is
a new generation of IoT connection management platform that China Mobile independently developed and gradually evolved over a period of 5 years.

The new CCMP3.0 mainly provides five aspects of capabilities, including business operation capabilities, application integration capabilities, international business
expansion capabilities, NB-IOT capabilities and security protection capabilities. Among them, the three capabilities of business operation, application integration and
security protection have
undergone a complete kernel update based on version 2.0 and evolved into new business capabilities; the two major capabilities of international business and NB-IoT
are the two newly launched capabilities . The large capabilities provide new possibilities for enterprise customers to expand cross-border business and provide richer IoT business scenarios.
