1. A method of performing a handover of a mobile network device from a first gateway device to a second gateway device, in an industrial facility comprising two or more production cells, wherein the mobile network device moves in between and within the two or more production cells for transporting material and work in process items between the two or more production cells, the method comprising:
determining the second gateway device from a plurality of gateway devices based on a movement information associated the mobile network device, wherein the movement information is indicative of a potential movement of the mobile network device from the first gateway device to the second gateway device;
coordinating a reservation of one or more radio resources at the second gateway device in relation to the mobile network device and coordinating a release of the one or more radio resources at the first gateway device in relation to the potential movement of the mobile network device; and
transmitting, by the first gateway device, a route control message to the mobile network device based on an unavailability of the one or more radio resources at the second gateway device prior to the mobile network device reaching radio range of the second gateway device,
wherein the movement information associated with the mobile network device is estimated based on process data associated with the mobile network device,
wherein the process data is obtained from a process controller associated with a first process, a manufacturing execution system associated with the first process, or a mobile network device controller associated with the mobile network device,
wherein the process data indicative of a first production cell,
wherein the mobile network device visits the first production cell for transfer of manufacturing material,
wherein the first production cell is within a radio coverage of the second gateway device, and
wherein the mobile network device, using the route control message, adjusts a velocity associated with the mobile network device to reach the radio range of the second gateway device at a time instance later than a predefined time instance after which resources at the second gateway device are available.
