Design and Implementation of Cloud Positioning System for Massive Intelligent Terminals

  Objectives  With the popularity of mobile devices and low-cost sensors, the universal positioning capability of mobile terminals has become a strong demand. In order to build a universally available cloud positioning system, it is necessary to use various positioning sensors in smart terminals to obtain wireless signals, and search in the positioning database to complete the calculation of the position.

  Methods  In light of smart phone devices in location based service(LBS) scenarios, we focus on location service for massive smart phone devices and put forward the cloud computing network architecture. The breakthroughs on key engineering technologies such as hierarchical cloud positioning capabilities, low-cost access for developers, fault tolerance strategy and distributed positioning services are gained.

  Results  The testing result shows that cloud positioning system has realized the access processing capability of hundreds of billions of requests per day.

  Conclusions  Consequently, the system can provide location services for hundreds of millions of users and can be widely used in various location based applications.
