Embodiments of the disclosure provide systems and methods for positioning a gateway of an architecture. The method may include determining a trajectory of a mobile device based on motion data acquired by the mobile device and a movement model, acquiring a first end position of the trajectory of the mobile device, detecting that the mobile device enters or exits the architecture, and determining a second end position of the trajectory upon the detection as the position of the gateway.
