Abstract
An apparatus controlling channel assignments for a shared access system is disclosed. The apparatus generates a first registration in a database that indicates that a first channel is assigned to a device and sends the identity of the first channel to the device. The device may use the first channel to communicate with other devices in the system. The apparatus may receive a query from the device indicating the first channel is encumbered. In response to the query, the apparatus may send the identity of a second channel to the device, generate a second registration in the database that indicates that the second channel is assigned to the device, and generate an amendment to the database indicating that the first channel is encumbered. The apparatus may then verify whether the first channel is encumbered and remove or keep the amendment in the database based on the verification.
