Claim 13:
14. A computer program product for setting up communication between a first wireless communication device and a second wireless communication device of an industrial automation system via a cellular network, the computer program product comprising;
a non-transitory computer readable medium and computer program code stored on said computer readable medium, wherein the computer program code, when run by a processor of a communication handling module of the first wireless communication device, causes the communication handling module to:
receive, while the first wireless communication device is attached to a first base station of the cellular network, a first message from the second wireless communication device via the first base station, said first message including information identifying a particular base station of the cellular network to which the second wireless communication device is attached,
investigate the information of the first message in order to identify said particular base station to which the second wireless communication device is attached,
if said particular base station to which the second wireless communication device is attached to is a second base station different from the first base station, further causes the communication handling module to:
investigate if one or more conditions for attaching to the second base station are fulfilled by the first wireless communication device, where one condition is that the second base station is allowable, and
send a response to the first message concerning the ability of the first wireless communication device to attach to the second base station,

wherein if said one or more conditions are fulfilled, the communication handling module is further caused to:
instruct a radio circuit of the first wireless communication device to detach, from the first base station and
instruct the radio circuit to attach to the second base station the second wireless communication device.
