1. A method comprising:
receiving, at a domain proxy, a request from a base station for allocation of a first portion of a frequency band to support cellular communication in a geographic area that is indicated in the request;
accessing, by the domain proxy from a database accessible to the domain proxy based on the request, a policy for the base station;
determining, by the domain proxy based on the policy for the base station, whether the base station is permitted to request allocation of resources from a spectrum access server (SAS) that is responsible for allocating portions of the frequency band; and
providing, from the domain proxy toward the SAS based on a determination by the domain proxy that the base station is permitted to request allocation of resources from the SAS, the request.
