Abstract
The present disclosure proposes a method and apparatuses for geographical zone based radio resource management. The geographical zone based radio resource management method adapted for a control node would receive from a user equipment a request to communicate in a Device to Device (D2D) mode of communication. The control node would validate the user equipment according to a geographical zone in which the user equipment is located in response to the request of the user equipment to communicate in the D2D mode, wherein the geographical zone is formed by at least three control nodes. The control node would then notify the user equipment whether the user equipment may communicate in the D2D mode after the user equipment is authorized.
