Method and System for Wireless Networking Using Coordinated Dynamic Spectrum Access

摘要

A method and system for coordinated dynamic access to radio spectrum for wireless networking includes defining a coordinated access band (CAB) from which radio access network (RAN) managers may request spectrum allocations in the form of time bound spectrum leases for their respective requesting base stations. In one embodiment of the present invention, a DIMSUMnet architecture is implemented to make some fundamental choices and to centralize the collection of information, such as spectral occupancy, thermal and adjacent frequency interference. Such collected information is subsequently used by a spectrum broker in making spectrum allocation decisions. The DIMSUMnet architecture of the present invention also introduces a RAN manager element to centralize the task of acquiring time bound spectrum leases and for configuring the base stations.

1. An apparatus, comprising:
a processor and a memory communicatively connected to the processor, the processor configured to:
determine spectrum requirements for a base station associated with a radio access network;propagate, toward a spectrum information management server, a request for dynamic allocation of radio spectrum for the base station based on the spectrum requirements for the base station;receive, from the spectrum information management server, a response comprising spectrum lease information of a spectrum lease of radio spectrum dynamically allocated to the base station by the spectrum information management server; andpropagate, toward the base station, configuration information adapted for use in configuring the base station based on the spectrum lease of radio spectrum dynamically allocated to the base station.
