Spectrum controller for cellular and wifi networks

A method comprising:

• obtaining metrics regarding a Wireless Local Area Network (WLAN) and a Radio Access Network (RAN) of a cellular network, the WLAN and the RAN having overlapping coverage ranges,
• based at least partly on said metrics, allocating a first adjusted spectrum allocation to a first network, of the WLAN and RAN, and a second adjusted spectrum allocation to a second network, of the WLAN and RAN, said first adjusted spectrum allocation decreased from a first current spectrum allocation for the first network, and said second adjusted spectrum allocation increased from a second current spectrum allocation for the second network;
• and
• causing enforcement of the first adjusted spectrum allocation and the second adjusted spectrum allocation,
• wherein said obtaining, allocating and causing are performed a plurality of times, and wherein in at least two of the plurality of times, said metrics are indicative that for the first network, the first current spectrum allocation is greater than or equal to a first current spectrum requirement for the first network, and that for the second network, the second current spectrum allocation is less than a second current spectrum requirement for the second network, and wherein in at least one of the at least two times the first network is the WLAN and the second network is the RAN, and in at least one other of the at least two times the first network is the RAN and the second network is the WLAN.

A computer program product, comprising a non-transitory computer readable medium having computer readable program code embodied therein, the computer program product comprising:

• computer readable program code for causing a computer to obtain metrics regarding a WLAN and a Radio Access Network (RAN) of a cellular network, the WLAN and the RAN having overlapping coverage ranges;
• computer readable program code for causing the computer to allocate, based at least partly on said metrics, a first adjusted spectrum allocation to a first network, of the WLAN and RAN, and a second adjusted spectrum allocation to a second network, of the WLAN and RAN, said first adjusted spectrum allocation decreased from a first current spectrum allocation for the first network, and said second adjusted spectrum allocation increased from a second current spectrum allocation for the second network;
• and
• computer readable program code for causing the computer to cause enforcement of the first adjusted spectrum allocation and the second adjusted spectrum allocation,
• wherein the computer readable program code for causing the computer to obtain, allocate and cause enforcement, causes the computer to obtain, allocate and cause enforcement a plurality of times, and wherein in at least two of the plurality of times, said metrics are indicative that for the first network, the first current spectrum allocation is greater than or equal to a first current spectrum requirement for the first network, and that for the second network, the second current spectrum allocation is less than a second current spectrum requirement for the second network, and wherein in at least one of the at least two times the first network is the WLAN and the second network is the RAN, and in at least one other of the at least two times the first network is the RAN and the second network is the WLAN.
