Section: 5.9.1 Description
Content: Considering beyond visual line-of-sight remote controlled UAV using cellular technologies can expose some public safety and security concerns in some countries, therefore there is a need to consider the case which needs to apply restriction on the fly range of a remote controlled UAV, such as to prevent out-of-sight flying, restriction on the distance range between the UAV and the UAV controller, or the geographic range of UAV can fly. In addition, because of the roaming consideration, preventing controlled UAV crossing different PLMNs may also be required. Therefore, to address those public security and charging issues, we should define and limit the fly range of the UAV, such as controlling range between UAV and UAV controller.
