What is DySPAN-SC?• IEEE Dynamic Spectrum Access Networks (DySPAN) Standards Committee

(DySPAN-SC)– Originated as IEEE P1900 -> IEEE SCC 41 -> DySPAN-SC– http://grouper.ieee.org/groups/dyspan/ – Home to the IEEE 1900 working groups– “Owns” the P1900 series of standards…

• Scope (from http://grouper.ieee.org/groups/dyspan/) – dynamic spectrum access radio systems and networks with the focus on

improved use of spectrum– new techniques and methods of dynamic spectrum access including the

management of radio transmission interference, and – coordination of wireless technologies including network management and

information sharing amongst networks deploying different wireless technologies

• Next meeting: Check http://grouper.ieee.org/groups/dyspan/

• This standard specifies policy language (PL) requirements and policy architecture (s) for policy-based dynamic spectrum access (DSA) radio systems. In this standard, a distinction is made between the policy reasoning that is accomplished within the Policy Based Radio (PBR) node and policy generation and validation that is accomplished through a policy generation system prior to provision of the policy to the PBR node. Policy reasoning may be distributed, i.e., it may take place either within a PBR node or in other elements of a policy based radio communications network.

Requirements from IEEE 1900.5 (there are many more)

• In order to evaluate policy languages options, it is important to know what the basic requirements are for the language. These were determined in developing IEEE 1900.5:

– A declarative language shall be used.– A policy language shall have clear and unambiguous syntax and semantics.– The policy language shall have the capability for annotations.– The policy language shall have a machine-understandable syntax.– The policy language may have an easily human understandable syntax. – The policy language shall support permissive policies and restrictive policies. – The policy language shall be capable of expressing inheritance and extension of policies.– The language shall be capable of specifying the dynamics (behaviors), including temporal

aspects, of policy based dynamic spectrum access radio system components. – The policy language shall include the ability to introduce definitions of new functions in terms

of other known functions and allow inferring relationships between two functions, such as whether two functions are equivalent or not.

– The expressivity of the policy language shall include the following: Classes, Individuals, Binary relations, Composition of relations, Functions, Temporal aspects of the system, Behavioral descriptions, State of the system, and Rules)

– The policy language shall be explicit about which negation [logical negation or negation as failure (NAF)] it supports.

IEEE P1900.5.1

• Title– Standard Policy Language for Dynamic Spectrum Access Systems.

• Scope– This standard defines a vendor-independent policy language for managing the functionality and

behavior of dynamic spectrum access networks based on the language requirements defined in the IEEE 1900.5 standard. The standard developed under this PAR will take into consideration both the Policy Language Requirements of IEEE 1900.5 and the results of the Modeling Language for Mobility Work Group (MLM-WG) within the Wireless Innovation Forum (SDRF v2) Committee on Advanced Wireless Networking and Infrastructure. MLM-WG is developing use cases, an ontology, corresponding signaling plan, requirements and technical analysis of the information exchanges that enable next generation communications features such as spectrum awareness and dynamic spectrum adaptation, waveform optimization, capabilities, feature exchanges, and advanced applications. The MLM-WG expects this effort to lead to specifications/standards for languages and data exchange structures to support these capabilities..

• Plus Procedural Attachments

IEEE P1900.5.2

• Title– Standard Method for Modeling Spectrum Consumption

• Scope– This standard defines a vendor-independent generalized method for modeling spectrum

consumption of any type of use of RF spectrum and the attendant computations for arbitrating the compatibility among models. The methods of modeling are chosen to support the development of tractable algorithms for determining the compatibility between models and for performing various spectrum management tasks that operate on a plurality of models. The modeling methods are exclusively focused on capturing spectrum use but are defined in a schema that can be joined with other schemata of business processes of spectrum management or behavioral aspects of spectrum policy.
