Policy-Based Protection of Non-Informing Spectrum Operations

摘要

A spectrum access system (SAS) and policy engine (PE) application are provided that facilitates the detection, classification and protection of a non-informing spectrum user in a spectrum sharing environment. The SAS may contain a policy database. Wireless access points with an embedded PE software application may retrieve a spectrum policy configuration specific to their immediate location and capabilities and may use the policy configuration to efficiently detect, classify and protect a non-informing spectrum user from radio frequency interference without disclosing details about the detected spectrum operations.

1. A system for protecting the spectrum operations of a non-informing user, comprising:
a. a spectrum access system configured to access a database; the database being configured to contain a plurality of spectrum access policy configurations; where
i. each of the individual policy configurations includes a radio frequency signal fingerprint, wherein a fingerprint consists of various technical parameters and metrics that may be used to more efficiently classify a specific type of radio frequency signal; andii. each of the individual policy configurations identifies a geographic region where the policy configuration is applicable; and b. a plurality of policy-enabled wireless access point devices, each of the plurality of devices being configured to:
i. identify its geographic position; andii. execute a spectrum access policy engine application; andiii. load the policy engine application with one or more policy configurations that each are applicable to the specific device's geographic location; and c. a spectrum access policy engine application; where
i. the policy engine application is capable of loading and operating in accordance with instructions contained within at least one policy configuration; andii. the policy engine application may continuously receive radio frequency signal information, compare the received signal information against at least one policy configuration and, if the received signal information matches the radio frequency signal fingerprint of a policy configuration, the policy engine application may cause the device executing the policy engine application to take at least one or more action prescribed in the matched policy configuration.
