Abstract:
A method and device for configuring cognitive radio system spectrum resources, relates to the field of wireless communication and solves the problem that the existing resource configuration mode influences system stability. The method includes: receiving, by a reconfiguration management node, idle spectrum resource request information transmitted by secondary user equipment, wherein the idle spectrum resource request information indicates a demand of the secondary user equipment for idle spectrum resources; and performing, by the reconfiguration management node, an idle spectrum resource configuration decision for the secondary user equipment according to current idle spectrum resource information and historical configuration information of the idle spectrum resources of the secondary user equipment. The technical solution provided by the embodiment of the present document is applicable to radio service, and realizes higher-efficiency idle spectrum resource configuration decision on the basis of historical data.
Abstract:
A method and apparatus for controlling a handover in a cognitive radio system are used to control a cell handover process of a user equipment, and can hand over the user equipment to an appropriate target cell as far as possible. The method includes: a source base station receiving a measurement report send by a user equipment; the source base station controlling a handover of the user equipment according to the measurement report, radio resource management information, and reconfiguration related information. The apparatus is located in the source base station and includes a receiving module and a handover controlling module.
Abstract:
The present disclosure discloses a dynamic spectrum allocation method and device based on channel management. The method comprises the following steps: a network node generates a channel set according to an available channel list and channel classification information, and maintains and updates the channel set; and the network node selects a spectrum from the channel set and allocates the spectrum. The device comprises: a channel set generation module configured to generate a channel set according to an available channel list and channel classification information and maintain and update the channel set; and a spectrum allocation module configured to select a spectrum from the channel set and allocate the spectrum. The present disclosure can reduce the delay in the spectrum resource reconfiguration of a CR system, improves the overall performance of spectrum resource reconfiguration and increases the utilization efficiency of a spectrum.
