Embodiment 1

[0129] Figure 5 It is a schematic flow chart of Embodiment 1 of the method for reconfiguring spectrum resources of the radio system in the present invention. This method is a specific embodiment of the corresponding method 1 for reconfiguring spectrum resources of the radio system. It is applied to the reconfiguration decision-making module located on the RBS. The first layer is the scenario of reconfiguration of access link spectrum resources in the radio system. In this embodiment, the reconfiguration decision-making module is CCP, such as Figure 5 As shown, the method includes the following steps:

[0130] Step 501, when spectrum resource reconfiguration is triggered, the CCP generates a reconfiguration command 1;

[0131] Specifically, when there is a primary user appearance, OAM configuration, a request from an adjacent reconfiguration decision-making module, and the RBS sends an application for idle spectrum resources, spectrum resource reconfiguration can be triggere...

Embodiment 2

[0147] Figure 6 It is a schematic flow chart of Embodiment 2 of the method for reconfiguring spectrum resources of a radio system in the present invention. This method is a specific embodiment of the corresponding method 1 for reconfiguring spectrum resources of a radio system. It is applied to the reconfiguration decision-making module located on the RBS. One layer, the scene of reconfiguration of backhaul link spectrum resources in the radio system, in this embodiment, the reconfiguration decision module is CCP, such as Figure 6 As shown, the method includes the following steps:

[0148] Step 601, trigger spectrum resource reconfiguration, CCP generates reconfiguration command 1;

[0149] Specifically, spectrum resource reconfiguration can be triggered when the primary user appears, the configuration of OAM, the request of the adjacent reconfiguration decision-making module, and the RBS sends an application for idle spectrum resources; Issue an application for idle spect...

Embodiment 3

[0168] Figure 7 It is a schematic flow chart of Embodiment 3 of the method for reconfiguring spectrum resources of a radio system in the present invention. This method is a specific embodiment of the corresponding method 2 for reconfiguring spectrum resources of a radio system. The reconfiguration decision-making module is located in the RBS. Based on the scenario of spectrum resource reconfiguration under UE working spectrum grouping, in this embodiment, the reconfiguration decision-making module is CCP, such as Figure 7 As shown, the method includes the following steps:

[0169] Step 701, when spectrum resource reconfiguration is triggered, the CCP of the RBS generates a reconfiguration command;

[0170] Specifically, spectrum resource reconfiguration can be triggered when the primary user appears, the network management side (OAM, Operation Administration and Maintenance) configures, the neighbor reconfiguration decision module requests, and the reconfigurable base stati...

Abstract

The invention discloses a radio system and a frequency spectrum resource reconfiguration method of the radio system. The method comprises the steps that when frequency spectrum resource reconfiguration is triggered, a reconfiguration order is generated by a decision-making reconfiguration module and is sent to a subsidiary RBS related with the frequency spectrum resource reconfiguration, the received reconfiguration order is sent to a subsidiary node by the RBS, and reconfiguration of frequency spectrum resources is executed by the RBS and the subsidiary node according to the reconfiguration order. According to the technical scheme, the radio system and the frequency spectrum resource reconfiguration method of the radio system can achieve the frequency spectrum resource reconfiguration of the radio system.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a radio system and a spectrum resource reconfiguration method thereof. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, and the spectrum resources on which radio services rely are limited. Facing the continuous increase in people's demand for bandwidth, spectrum resources are extremely tense; On the one hand, under the traditional fixed spectrum allocation system, the utilization rate of spectrum resources is not high. In a sense, it is this spectrum allocation system that is fixedly assigned to the authorized system that has caused the extremely tight situation of spectrum resources. [0003] Cognitive radio technology breaks the fixed spectrum allocation system in the traditional sense, dynamically allocates the spectrum between systems, and improves the efficiency of spectrum...
