Protocol reference model, security and inter-operability in a cognitive communications system
First Claim
1. A cognitive radio communications system, comprising:
- a cognitive device, the device including;
a Data Plane including Physical (PHY) and Media Access Control (MAC) Layers operatively coupled to one another;
a Management Plane having one or more management entities configured to interface with the PHY and MAC Layers, and at least one of a Station Management Entity (SME) and a Network Control and Management System (NCMS) configured to control operation of the system;
a Cognitive Plane having a Spectrum Manager (SM) and one or more Security Sublayers between the SM and the Management Plane, the Cognitive Plane configured to interface with at least one of the one or more management entities and determine whether additional resources including a wireless spectrum are available to enable communication; and
at least one of a Service Access Point (SAP) and/or an informal interface separating the Cognitive Plane from the Management Plane and the Data Plane, such that the Cognitive Plane and its functions are partitioned from and implemented separately from the Management Plane and the Data Plane, thereby allowing interoperability between cognitive devices and non-cognitive devices such that a non-cognitive device may receive information on spectrum access from a cognitive device.

Abstract
Various cognitive communications system architectures and their corresponding Protocol Reference Models (PRMs) are disclosed. Such PRMs incorporate a Cognitive Plane in addition to conventional Data and Management Planes. The additional Cognitive Plane functionality may include, for example, spectrum sensing, spectrum management, geolocation, and security functions. The Cognitive Plane may further include a Policy Engine and a Learning and Reasoning Module. In some embodiments, Management Plane functions may be effectively combined to form a database of primitives (and their respective values) called a Management Information Base (MIB). In addition, techniques are provided by which various components of cognitive and non-cognitive, as well as mesh-enabled and non-mesh-enabled nodes in a network, inter-operate with each other. The architectures allow a Spectrum Manager (or Signal Space Manager) to combine information from various network layers (e.g., PHY/MAC Layers, Spectrum Sensing Function, Geolocation Function, and/or Security Sublayers), and to make informed decisions on spectrum utilization.
