Abstract

Embodiments use the principles of self-organizing networks to allocate resources to allow spectrum owners to share spectrum with wireless carriers according to defined license conditions. A spectrum licensee holds the licensing conditions of the spectrum licensed by the spectrum owners. This licensed spectrum is referred to as secondary spectrum. A self-organizing network server requests access to secondary spectrum. The spectrum licensee grants access to the secondary spectrum along with the licensing conditions for access. The self-organizing network server monitors the conditions associated with the license and/or delegates the responsibility for monitoring conditions associated with the license to others. When the license conditions are met, enhanced Node B systems may begin using the secondary spectrum according to the license conditions. When the license conditions are no longer met, enhanced Node B systems discontinue use of the secondary spectrum.

Claims

1. A method performed by a network component, comprising:

requesting access to a secondary band having a particular capacity condition, geographic region condition, and time period condition;

determining that one of the conditions for the selected secondary band option may be used is no longer met;

based on determining the condition is no longer met, discontinuing use of the secondary band.

a geographic region where the secondary band may be used;

a geographic region when;

the secondary band may not be used;

a time at which the secondary band may be used;

a time at which the secondary band may not be used;

a demand threshold above which the secondary band may be used;

a demand threshold below which the secondary band may not be used;

presence of a spectrum owner;

absence of the spectrum owner; and

combinations thereof.

3. The method of claim 2, further comprising sending a message to indicate the secondary band has been activated upon determining that the conditions have been met.
