Embodiment 1

[0054] image 3 It is a flowchart of a wireless link configuration method provided by an embodiment of the present invention, and the specific steps are as follows:

[0055] Step 1: BS sends WS resource application to CCP, and CCP sends WS resource request to DB after receiving WS resource application message sent by subordinate BS;

[0056] The reason for triggering may be that the communication quality of the subordinate link of the BS cannot meet the QoS requirement, or the load is too heavy.

[0057] Step 2: According to the load status information, communication quality status information, and spectrum etiquette stored in the coverage of each central control node, the DB makes a coordinated allocation decision between the central control nodes for the main system WS spectrum resources;

[0058] The coordinated allocation includes allocating the WS spectrum resource to the CCP that issued the application, and ordering the central control node with a currently light load t...

Embodiment 2

[0075] Figure 4 It is another signaling flowchart for wireless link configuration provided by the embodiment of the present invention, and the specific steps are as follows:

[0076] Step 1: BS triggers sending WS resource application to CCP, and CCP sends WS resource request to DB after receiving WS resource application message sent by subordinate BS;

[0077] The reason for triggering may be that the communication quality of the BS subordinate link cannot meet the QoS (Quality of Service) service quality requirement, or the load is too heavy.

[0078] Step 2: According to the load status information, communication quality status information, and spectrum etiquette stored in the coverage of each central control node, the DB makes a coordinated allocation decision between the central control nodes for the main system WS spectrum resources;

[0079] In this embodiment, the DB will allocate a plurality of WS spectrum resources to the CCP sending the application for selection. ...

Embodiment 3

[0091] Figure 5 It is the database triggering CCP to perform WS spectrum resource reconfiguration signaling process provided by the embodiment of the present invention, and the specific steps are as follows:

[0092] Step 1: DB coordinates and allocates WS resources between CCPs;

[0093] The reason for the coordinated allocation may be that when a CCP sends out a WS spectrum resource application in Embodiment 1, the DB triggers the reconfiguration of the WS resources of the relevant CCP; or the DB optimizes the overall performance and orders a CCP with a lighter load or a better communication quality. Release some WS resources.

[0094] Step 2: DB sends WS reconfiguration command to relevant CCP;

[0095] Step 3: According to the reconfiguration command of DB, CCP makes WS spectrum resource coordination decision;

[0096] If the WS spectrum resource specified by the DB is occupied by a BS with a lighter load or better communication quality, you can directly execute the re...

Abstract

The invention discloses a wireless link configuration method and a system thereof. The method comprises the following steps that: base stations send idle frequency spectrum resource applications to center control nodes which the base stations belong to, the center control nodes collect the idle frequency spectrum resource applications and initiate an idle frequency spectrum resource distribution request to database which the center control nodes belong to; the database coordinates and distributes idle frequency spectrum resources between the subordinate center control nodes according to the idle frequency spectrum resource distribution request; the center control nodes response the database so as to complete the idle frequency spectrum resource coordination distribution. By using the method and the system of the invention, an interference problem between secondary systems, which may be generated when a plurality of the secondary systems or a plurality of operators compete against each other for a main system resource, can be solved; simultaneously, fairness for the each secondary system or the operator to access to the main system idle frequency spectrum can be guaranteed; the interference problem which may be generated between the base stations of the secondary systems or the operators can be solved; and the access fairness of the base stations can be guaranteed.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular, to a cognitive radio technology and a database coordination method for allocating spectrum resources. 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. Realize that the busy system (secondary system) borrows the spectrum resources of the system (primary system) with low spectrum utilization rate, and the secondary system adopts a certain protection mechanism, so as to improve the overall network spectrum without causing interference to the primary system. resource utilization. Th...
