METHOD AND APPARATUS FOR DYNAMIC SPECTRUM MANAGEMENT
First Claim
1. A dynamic spectrum management (DSM) engine, comprising:
- a policy engine configured to maintain policies and opportunistic spectrum availability information; and
a channel management function (CMF) linked to the policy engine and configured to obtain opportunistic spectrum resource information from at least the policy engine to maintain a pool of opportunistic spectrum resources, perform radio resource management (RRM) and allocate aggregated spectrum resources in response to requests from devices that have been admitted by the CMF.

Abstract
Described herein are methods, apparatus and architecture for dynamic spectrum management (DSM) including protocol stacks, logical entities and functionalities that support DSM operation in opportunistic spectrum such as television white space (TVWS). The architecture supports aggregating bandwidth at the internet protocol (IP) layer over licensed and opportunistic bands as well as noncontiguous spectrum aggregation at the medium access control (MAC) layer. The control plane protocol stack includes a multi network transport protocol (MNTP), a channel management (CM) protocol, a policy protocol, a medium access control (MAC) entity, a physical entity and an air interface, all of which are configured to allocate, monitor, and update aggregated spectrum resources with respect to a DSM client.

11. A dynamic spectrum management (DSM) client, comprising:
-
a channel management function-client (CMF-C) configured to obtain allocated aggregated spectrum resources from a channel management function (CMF) and handle control communications with the CMF; a multi network connection (MNC) client configured to enable IP aggregation and determine network health from network information received from the CMF-C; and a DSM link function configured to initiate and maintain connectivity with a DSM engine, the DSM link function being managed by the CMF-C. - View Dependent Claims (12, 13, 14, 15)

16. A method of dynamic spectrum management (DSM), comprising:
-
determining, by a CMF, a pool of available channels; on a condition that a sensing mode is supported and the pool of available channels is deficient, using the sensing mode to determine usability of additional channels in opportunistic bands; selecting channels from the pool of available channels; allocating aggregated channels from the pool of available channels for a control channel; and transmitting a control message over the aggregated channels to the devices. - View Dependent Claims (17, 18, 19, 20)
