Abstract:
Apparatus, systems, and methods are disclosed for determining dynamic positioning of mobile cells. Dynamic positioning provides for navigating a mobile cell, such as an unmanned aerial vehicle or the like, to a location suitable for offloading current network traffic, such that the suitable location maximizes offloading capabilities. The methodology describes takes into account both the current traffic load on the network and the location of the highest system capacity-intensive mobile terminals in determining an initial position for deploying the mobile cell. Additionally, the location of the deployed mobile cell is optimized, over time, based on tracking the direction of movement of the highest capacity-intensive mobile terminals, and, in some embodiments, service quality indicators provided by the mobile terminals and/or contextual information captured by the mobile cell apparatus.
