Abstract
A dynamic spectrum allocation method and device are provided. The method includes: finding non-idle frequency bands in the coverage of a communication device according to information in a database; selecting a frequency band from the non-idle frequency bands as a negotiation frequency band, and sending a spectrum assignment request to an interfering device using the negotiation frequency band; and acquiring usage assignment of the interfering device, in which the usage assignment is a response to the spectrum assignment request. The technical solutions can effectively allocate dynamic spectrum resources to a communication device, and are simple to implement.
Claims16
A dynamic spectrum allocation method, comprising:
- finding at least a non-idle frequency band in the coverage of a communication device according to information in a database;
- selecting a frequency band from the at least a non-idle frequency band as a negotiation frequency band, and sending a spectrum assignment request to an interfering device using the negotiation frequency band;
- and
- acquiring usage assignment of the interfering device, wherein the usage assignment is a response to the spectrum assignment request.
A dynamic spectrum allocation method, comprising:
- acquiring a spectrum assignment request, wherein the spectrum assignment request comprises information of a negotiation frequency band;
- determining whether to accept the spectrum assignment request according to a use time and a bandwidth of the negotiation frequency band currently being used;
- and
- sending usage assignment when the spectrum assignment request is accepted.
A dynamic spectrum allocation device, comprising:
- a finding module, configured to find at least a non-idle frequency band in the coverage of a communication device according to information in a database;
- a selection module, configured to select a frequency band from the at least a non-idle frequency band as a negotiation frequency band, and send a spectrum assignment request to an interfering device using the negotiation frequency band;
- and
- a permit reception module, configured to acquire usage assignment of the interfering device, wherein the usage assignment is a response to the spectrum assignment request.
A communication device, comprising:
- a request reception module, configured to acquire a spectrum assignment request, wherein the spectrum assignment request comprises information of a negotiation frequency band;
- a determination module, configured to determine whether to accept the spectrum assignment request according to a use time and a bandwidth of the negotiation frequency band currently being used;
- and
- a sending module, configured to send usage assignment when the spectrum assignment request is accepted.
