China Tower Corporation Limited, world’s largest telecommunications tower infrastructure service provider, has piloted the effort of establishing mission critical convergent LTE networks in China, and recently launched a convergent network for emergency communications and dispatching in Guang'an, Sichuan, a southwestern province. 

China Tower did comprehensive researches into customers' needs, and launched the network after two years planning, development and deployment. It established a digital trunking network with digital trunking handheld terminals, vehicle mounted terminals, radio base stations and drones, and formed a city/county-level emergency communication platform through unified scheduling management in the background. At the same time, it integrates push-to-talk-over-cellular voice, CCTV and other systems. The platform can be shared and accessed by multiple departments of government in case of emergencies.
