1. A method of controlling spectrum use in a plurality of wireless communications systems, the method comprising:
- providing each wireless communication system with a respective gateway;
effecting an instance of a long-term spectrum assignment process following an elapse of a time period of minutes determined in dependence on network conditions;
performing the long-term spectrum assignment process among the wireless communication systems by exchange of information among the gateways, the exchange of information including a preferred spectrum configuration of each gateway, and the long-term spectrum assignment process including one of the wireless communication systems assigning a portion of spectrum to at least one of another wireless communication systems; and
only when not performing the long-term spectrum assignment process, performing a short-term spectrum assignment process within each wireless communication system on a timescale of seconds, the short-term spectrum assignment process being performed multiple times within said time period of minutes.

Abstract
A method of controlling spectrum use in a first wireless communications system which is operable to take part in a spectrum assignment process involving a plurality of wireless communications systems including the first wireless communications system, in which spectrum assignment process one of the said wireless communications systems assigns a portion of spectrum to at least one of the other said wireless communications systems. The method comprising effecting an instance of the spectrum assignment process in response to a trigger which is based on network conditions.

17. A non-transitory storage medium on which is stored a computer program which, when run on a computer forming part of a gateway acting as a network element or an external controlling element of a wireless communication system, causes the computer to perform a method of controlling spectrum use in a plurality of wireless communications systems, the method comprising:
-
providing each wireless communication system with a respective gateway; effecting an instance of a long-term spectrum assignment process following an elapse of a time period of minutes determined in dependence on network conditions; performing the long-term spectrum assignment process among the wireless communication systems by exchange of information among the gateways, the exchange of information including a preferred spectrum configuration of each gateway, and the long-term spectrum assignment process including one of the wireless communication systems assigning a portion of spectrum to at least one of another wireless communication systems; and only when not performing the long-term spectrum assignment process, performing a short-term spectrum assignment process within each wireless communication system on a timescale of seconds, the short-term spectrum assignment process being performed multiple times within said time period of minutes.
