Embodiment 1

[0159] The flow chart of an embodiment of configuring spectrum as a supplementary downlink carrier according to BS requirements and adjacent frequency system information is as follows Figure 5 As shown, the specific description is as follows:

[0160] Step 1: BS sends a resource configuration request message to SC;

[0161] The resource configuration request message is used to request idle spectrum resource configuration to the SC. In addition to the basic information of the resource configuration request message (including: BS equipment parameters, location information, etc.), the message also includes the resource requirements of the BS information, specifically:

[0162] The purpose of idle spectrum resource allocation: to offload the downlink load as a supplementary downlink carrier;

[0163] Bandwidth requirement: 5MHz

[0164] Frequency point: 470-790MHz

[0165] Transmission power requirement: 30dBm

[0166] Step 2: After receiving the resource configuration reque...

Embodiment 2

[0177] According to the BS capability and the operator's strategy, the frequency spectrum is configured to independently operate the TDD carrier. The flow chart of the embodiment is as follows Figure 6 As shown, the specific description is as follows:

[0178] Step 1: BS sends a measurement report message to SC;

[0179] The measurement report message is used to indicate the current network state to the SC, so that the SC can judge whether to initiate resource reconfiguration for the BS according to the network state.

[0180] This measurement report message shows that the current subordinates of the BS are configured in a TDD cell with f1=520MHz and a bandwidth of 5MHz, which is greatly interfered, and the SINR value is too low to meet the system performance requirements.

[0181] Step 2: After receiving the measurement report message sent by the BS, the SC determines that it is necessary to initiate resource reconfiguration of the BS to improve the interference situation o...

Embodiment 3

[0196] The flow chart of an embodiment of configuring a designated frequency band as a time-division duplex secondary carrier in carrier aggregation according to the adjacent frequency system information of current idle spectrum resources is as follows Figure 7 As shown, the specific description is as follows:

[0197] Step 1: BS sends a resource configuration request message to SC;

[0198] The resource configuration request message is used to request idle spectrum resource configuration to the SC. In addition to the basic information of the resource configuration request message (including: BS equipment parameters, location information, etc.), the message also includes the resource requirements of the BS information, specifically:

[0199] Use of idle spectrum resources: the load is too heavy to meet the service needs of subordinate terminals;

[0200] Bandwidth requirement: 5MHz

[0201] Frequency point: 470-790MHz

[0202] Transmission power requirement: 30dBm

Abstract

The invention provides a dynamic spectrum configuration method, a dynamic spectrum configuration device and a dynamic spectrum configuration system, and relates to the field of mobile communication. The problem that signaling interaction cost and processing delay are increased due to invalid configuration decision is solved. The method comprises the following steps: a configuration management node acquires the resource state information of a specified frequency band, wherein the resource state information is used for determining the configuration parameters of a communication site on the specified frequency band; and the configuration management node sends a configuration response message to the communication site, wherein the configuration response message carries the configuration parameters. The technical scheme provided by the invention is applicable to an international mobile phone system. Policy configuration guaranteeing optimal network performance is realized.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a dynamic frequency spectrum 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, in the traditional fixed spectrum allocation mode, the spectrum is first allocated to services (Allocation), then allocated to regions or countries or departments, and finally assigned to specific communication sites. Spectrum resources are subject to fixed Distribution constraints, but reflect the low utilization rate. 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 spec...
