1900.4 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

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.

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 1900.4 Scope: Protocols section 5.2 of 1900.4 PAR: "The corresponding protocols definition related to the information exchange will be addressed at a later stage." Protocols will be defined in 1900.4.1 (PAR proposal currently under SCC41 review)

Architecture

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

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

Policy based management Decision making in this standard is based on policy-based management framework. 1900.4 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: 1900.4 policy framework enables to define policies such as "if terminal location= [x,y], terminals may connect to 802.11 available at frequency f1" "all terminals shall report sensing measurement on Band [f1, f2], between StartTime and EndTime"
