Resource management method and system thereof
The present invention provides a resource management method and system thereof. The resource management method includes: judging whether the variation degree of work state of a communication system will result in the change of resource management information of the communication system or not, if so, then the resource management information is re-collected, wherein the resource management information includes the state, the interference state among links and service stream information relating to each node in the communication system; and determining the resource allocation strategy of the communication system according to the resource management information.
1. A spectrum sensing device which used in a communication system, the communication system comprising a primary system network and at least one secondary system network, the primary system network having a higher priority than the secondary system network for using at least one communication resource, the at least one communication resource sharable with the secondary system network, and the secondary system network sharing said communication resource when the primary system network is not interfered, the spectrum sensing device configured to:
measure resource management information including at least one of incumbent signals and interference signals,
report the measured resource management information,
before the measurement, receive measurement requests from a geo-location function device, and
after the measurement, report to the geo-location function device.
2. The device according to claim 1 , wherein resource management information in the communication system includes information of changes of a variation degree of communication system operation statues.
3. The device according to claim 1 , wherein
nodes in the communication system, which measure resource management information can be chosen as a spectrum sensing device.
4. The device according to claim 1 , wherein the geo-location function device is configured to:
use a measurements result of the resource management information obtained from the spectrum sensing device to estimate interference level, and
consider the interference level estimation to calculate an allowable maximum output power level.
5. The device according to claim 1 , the spectrum sensing device further configured to:
measure the resource management information from the primary system network and a primary user.
6. The device according to claim 1 , the spectrum sensing device further configured to:
measure the resource management information from the secondary system network and a secondary user.
7. The device according to claim 1 , the spectrum sensing device further configured to:
manage a coexistence function of the primary system network and the at least one secondary system network based on the measured resource management information.
8. The device according to claim 1 , the spectrum sensing device further configured to:
include geo-location information with the resource management information.
9. The device according to claim 1 , the spectrum sensing device configured to:
process the measured resource management information in the communication system in a neighborhood, and
access a channel quality due to a presence of another device or system in the neighborhood.
