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.
