Abstract: The present invention relates to commissioning in the presence of multiple networks. A network node, which is expected to join a second network, joins a first network and enters a second state from a first state once it has joined the first network. Once it has received from the first network a message to leave it, it enters a third state from the second state. The network node entered the third state becomes responsive with respect to the first network and/or the second network by receiving a dedicated message to join network or is unresponsive with respect to the first network. Then, it enters the first state from the third state once the network node has received the dedicated message from a coordinator of the first network after closing the first network and/or from a coordinator of the second network, or upon expiry of a timer.

Abstract: A Satellite Radio Access Network includes a base station for communicating with standard compliant user equipment (UE) via a satellite having a field of view. A network broadcasting signal is provided via an inactive or access beam covering a plurality of cells in the field of view. An access request is detected from a user device, such as a smartphone, within an area covered by the inactive beam. In response to the access request, a beam is transitioned from inactive to active to provide network access to the user device. Once the user device is out of range, the active beam is transitioned back to an inactive beam. An inactivity timer is used to detect an idle active cell that should be transitioned to an inactive cell.
