Spectrum sharing with switching of tier levels between networks and/or devices
In a device including a processor and a memory in communication with the processor, the memory includes executable instructions that, when executed by the processor, cause the processor to control the device to perform functions of connecting a remote device to a network via a first channel associated with a first tier level; determining that a tier level switch condition is met; sending, to a controller of the network, a request for tier level switch from the first tier level to a second tier level; receiving, from the controller of the network, an authorization for switching from the first tier level to the second tier level; and connecting the remote device to the network via a second channel associated with the second tier level.

10. A method of operating a device connected to a network and configured to connect a wireless device to the network, the method comprising:
establishing, via a first channel of a frequency spectrum available for the network, a first wireless connection with a first wireless device, wherein the first wireless device is associated with a first tier level which prohibits access to a second channel of the frequency spectrum unless authorized by a controller of the network, the second channel reserved for a second wireless device having a second tier level which permits access to the second channel of the frequency spectrum;
determining, based on a channel quality of the first channel, that a channel switch condition is met, which requires switching from the first channel to the second channel of the frequency spectrum;
in response to determining that the channel switch condition is met, sending, to the controller of the network, a request for channel switch from the first channel to the second channel of the frequency spectrum;
receiving, from the controller of the network, an authorization for switching from the first channel to the second channel of the frequency spectrum; and
in response to receiving the authorization from the controller of the network, establishing a second wireless connection with the first wireless device via the second channel of the frequency spectrum.
11. The method of claim 10 , wherein further comprises receiving, from the controller of the network, an assignment of the first channel.
12. The method of claim 10 , wherein determining that the channel switch condition is met comprises determining that a level of interference on the first channel meets a predetermined threshold value.
13. The method of claim 10 , wherein determining that the tier level channel switch condition is met comprises monitoring a parameter of the first channel.
14. The method of claim 13 , wherein the parameter comprises a bit error rate parameter, a packet error rate parameter, a channel throughput parameter or a QoS parameter of the first channel.
