With the rapid development of information technology, the world has entered an era of explosive growth of information, the Internet, the Internet of Things, and sensor networks have flooded with massive amounts of human society related information, providing us with a new way to solve urban governance and social management issues. The biggest challenge to further improve the ability of urban smart management is that information cannot be integrated and shared quickly and effectively. Therefore, the global location information superposition protocol and location-based service network technology have been proposed, based on the location-based fact of most social information, which become a key technology to break the barriers between systems in various fields, and to make the automatic collection, integration of computing, and intelligent services of massive heterogeneous information across networks, platforms, systems, and languages come true. This paper summarizes the current domestic and foreign research progress on the key technologies of the global location information superposition protocol and location-based service network, and then introduces the demonstration application of the global location-based service network. Finally, the technology and application of the global location-based service network on the future research directions are discussed, which can be the reference for the development of the global location-based service network in the future.
