Method and Apparatus for Efficient Spectrum Management in a Communications Network
First Claim
1. A method for efficient management of hierarchically administered spectrum resources in a communications network, comprising:
- receiving a request for a policy decision from a policy enforcement point at a current policy decision point level in a hierarchy of policy decision points;
determining whether the request can be satisfied at the current policy decision point level, wherein if the request cannot be satisfied at the current policy decision point level, forwarding the request to a policy decision point at a policy decision point level that is higher in the hierarchy, otherwiseretrieving policy information from a policy database;
determining a policy decision, wherein if the request was received from the policy enforcement point at the current policy decision point hierarchy level, sending the policy decision to the policy enforcement point at the current policy decision point level in the hierarchy, otherwise,sending the policy decision to a policy decision point level lower in the hierarchy.

Abstract
A method and apparatus for efficient management of hierarchically administered spectrum resources in a communications network are disclosed. The method may include receiving a request for a policy decision from a policy enforcement point at a current policy decision point level in a hierarchy of policy decision points, determining whether the request can be satisfied at the current policy decision point level, wherein if the request cannot be satisfied at the current policy decision point level, forwarding the request to a policy decision point at a policy decision point level that is higher in the hierarchy, otherwise retrieving policy information from a policy database, determining a policy decision, wherein if the request was received from the policy enforcement point at the current policy decision point hierarchy level, sending the policy decision to the policy enforcement point at the current policy decision point level in the hierarchy, otherwise, sending the policy decision to a policy decision point level lower in the hierarchy.

8. An apparatus that provides efficient spectrum management of a communications network, comprising:
-
a policy database; and a policy decision point that receives a request for a policy decision from a policy enforcement point at a current policy decision point level in a hierarchy of policy decision points, determines whether the request can be satisfied at the current policy decision point level, wherein if the request cannot be satisfied at the current policy decision point level, the policy decision point forwards the request to a policy decision point at a policy decision point level that is higher in the hierarchy, otherwise the policy decision point retrieves policy information from the policy database, determines a policy decision, wherein if the request was received from the policy enforcement point at the current policy decision point hierarchy level, the policy decision point sends the policy decision to the policy enforcement point at the current policy decision point level in the hierarchy, otherwise, the policy decision point sends the policy decision to a policy decision point level lower in the hierarchy. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A cognitive radio device, comprising:
-
a policy database; and a policy decision point that receives a request for a policy decision from a policy enforcement point at a current policy decision point level in a hierarchy of policy decision points, determines whether the request can be satisfied at the current policy decision point level, wherein if the request cannot be satisfied at the current policy decision point level, the policy decision point forwards the request to a policy decision point at a policy decision point level that is higher in the hierarchy, otherwise the policy decision point retrieves policy information from the policy database, determines a policy decision, wherein if the request was received from the policy enforcement point at the current policy decision point hierarchy level, the policy decision point sends the policy decision to the policy enforcement point at the current policy decision point level in the hierarchy, otherwise, the policy decision point sends the policy decision to a policy decision point level lower in the hierarchy. - View Dependent Claims (16, 17, 18, 19, 20)
