Patent Policy and Procedures: The contributor is familiar with the IEEE P1900 Patent Policy and Procedures < ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within IEEE P1900.

3. Standard Scope
To address radio resource management in composite wireless network
Multiple Radio Access Technologies
IEEE 802.xx, Cellular 2nd, 3rd generation
In Dynamic Spectrum Access context
also addresses optimization of resources in fixed spectrum allocation
Sponsor Ballot completed in November 2008
Approved By RevCom on Jan 19th 2009

4. Principles Network-device distributed decision making
The network manages the overall resource optimization, but is not in charge of full management of individual radio resource allocation.
The constraints are called "Policies" and are sent to terminals via a "radio enabler"
Terminals take decisions autonomously, respecting some constraints imposed by the network.

5. 1900.4 Content Architecture Information Model
Entities on network side
Entities on terminal side
Interfaces with these entities
Information Model
Type, nature, structure of the information to be exchanged via the defined interfaces
object-oriented approach
NOT in the Scope: Protocols
section 5.2 of PAR: "The corresponding protocols definition related to the information exchange will be addressed at a later stage."
Protocols will be defined in (PAR proposal currently under SCC41 review)

6. Architecture

7. Network entities Operator Spectrum Manager (OSM)
generates spectrum assignment policies expressing the regulatory framework
enables to control dynamic spectrum assignment decisions of NRM
Network Reconfiguration Manager (NRM)
analyzes spectrum assignment policies and available context information
dynamically make spectrum assignment decisions
dynamically generate radio resource selection policies and send them to Terminal Reconfiguration Managers.
RAN Reconfiguration Controller (RRC)
controls reconfiguration of Radio Access Networks based on requests from NRM
RAN Measurement Collector (RMC) collects RAN context information and provides it to NRM

8. Terminal Entities Terminal Measurement Collector (TMC)
collects terminal context information and provides it to TRM (e.g. sensing report)
Terminal Reconfiguration Manager (TRM)
analyzes these radio resource selection policies sent by Network Reconfiguration Manager
makes spectrum access decisions within the framework of the radio resource selection policies.
requests corresponding reconfiguration of its Terminal.
Terminal Reconfiguration Controller (TRC)
controls reconfiguration of terminal based on requests from TRM

9. Policy based management
Decision making in this standard is based on policy-based management framework.
enables to describe policies of type Event- Condition-Action
Radio resource selection policies create the framework within which TRMs will make terminal reconfiguration decisions
Examples: policy framework enables to define policies such as
"if terminal location= [x,y], terminals may connect to available at frequency f1"
"all terminals shall report sensing measurement on Band [f1, f2], between StartTime and EndTime"
