Embodiment 1

[0109] Figure 8 It is a schematic flow chart according to the preferred embodiment 1 of the present invention. During the initial access process of the idle spectrum of the secondary user equipment in the management mode, the SC obtains the uncoordinated secondary user equipment spectrum usage information required for decision-making. The embodiment flow is as follows Figure 8 As shown, a detailed description is given below:

[0110] Step S802: BS 1 Send a coordinated channel request (Coordinated_Channel_Request) message to the SC;

[0111] Coordinated_Channel_Request message contains BS 1 location information, device parameters, idle spectrum access request indication information, and basic requirements for spectrum;

[0112] The location information and equipment parameter information of BS1 are used by the SC to apply to GLDB for the free spectrum of the main system, and to determine the transmission power limit based on the protection of the main system;

[0113] Con...

Embodiment 2

[0141] Figure 9 It is a schematic flow diagram according to the second preferred embodiment of the present invention. In the process of reconfiguring the resources of the secondary user equipment in the information mode, the configuration management node obtains the spectrum usage information of the uncoordinated secondary user equipment. The embodiment flow is as follows Figure 9 As shown, a detailed description is given below:

[0142] Step S902: BS 1 Send a resource reconfiguration request (Resource_Reconfiguration_Request) message to the SC;

[0143] The Resource_Reconfiguration_Request message includes BS1's location information, device parameters, and idle spectrum access request indication information, as well as basic requirements for spectrum;

[0144] where BS 1 The location information and equipment parameter information are used by the SC to apply to the GLDB for the free spectrum of the main system, and to determine the transmission power limit based on the p...

Embodiment 3

[0173] Figure 10 It is a schematic flow chart according to the third preferred embodiment of the present invention, the process of sending the uncoordinated secondary user equipment spectrum usage information request and the uncoordinated secondary user equipment spectrum usage information response as independent messages is as follows: Figure 10 As shown, a detailed description is given below:

[0174] Step S1002: the SC sends a request message for spectrum utilization information of the uncoordinated secondary user equipment to the GLDB;

[0175] The above-mentioned uncoordinated secondary user equipment spectrum usage information request message is used to request the use of idle spectrum resources by the uncoordinated secondary user equipment within a specific area range and within a specific frequency band range.

[0176] The message includes: the area range to be obtained, the frequency band range to be obtained (470-790MHz), and the type of uncoordinated secondary us...

Abstract

A spectrum resource configuration method, device and system. The method comprises: sending, by a configuration management node, a first request message used for requesting to acquire usage information about the spectrum of a non-conforming secondary user equipment; and receiving, by the configuration management node, a first response message carrying the usage information about the spectrum of the non-conforming secondary user equipment, and making a decision about an idle spectrum resource configuration according to the usage information or providing the usage information to a subordinate secondary user equipment. The present invention solves the problem in the related art that interference between a non-conforming secondary user equipment and a conforming secondary user equipment is not taken into account, and avoids the malicious competition between the two types of secondary user equipment for the idle spectrum resource, thereby improving the network performance and the spectrum efficiency.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a frequency spectrum resource configuration method, device and system. 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; and On the other hand, under the traditional fixed spectrum allocation mode, 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. The cognitive radio technology breaks the fixed spectrum allocation system in the traditional sense, and dynamically allocates the spectrum between systems, improving the utilization efficienc...
