In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
Referring to fig. 1, a block diagram of a baseband resource system according to an embodiment of the present invention is shown, where the baseband resource system may include an access network element a, a baseband board element B, an intermediate network element C, and a combining matrix D. Wherein the access network element a may comprise a GSC (Gateway Station Controller ), an OMC (Operation Management Center, operation maintenance center), which may be used for control of the baseband resource system, and selection of baseband boards; the baseband boards may include a CPB board (Channel Processing Board ) which is described below as an example of a CPB board.

The combining matrix D may include an IN (input) port and an OUT (output) port, where there is a corresponding mapping relationship between the IN port and the OUT port, and the mapping relationship may be preconfigured; wherein, an IN port can be mapped to an OUT port, an OUT port can correspond to a plurality of IN ports, and different OUT ports can correspond to different polarization directions; for example, a 1 OUT port may correspond to a horizontal polarization direction and a 2 OUT port may correspond to a vertical polarization direction. The CPB board may be connected to the IN port of the combiner matrix through the RRU and the combiner IN the intermediate network element C, and then mapped to the corresponding OUT port, where the polarization direction of the OUT port is the polarization direction (hereinafter referred to as the polarization attribute) of the CPB board.

IN an example of the present invention, after determining the polarization attribute of the CPB board according to the baseband resource system, resource information of the CPB board (for example, information of the polarization attribute of the CPB board, a record number associated with the CPB, an IN port and an OUT port of the combining matrix, a use state, etc.) may be reported to the GSC IN advance; and then the GSC can generate first baseband resource information, such as a baseband resource information pool A, according to the resource information of the used CPB and the resource information of the associated CPB corresponding to the used CPB. The GSC may also generate second baseband resource information, such as baseband resource information pool B, according to the resource information of the unused CPB board. After the first baseband resource information and the second baseband resource information are established in advance, a baseband board matched with the cell to be established can be searched from the first baseband resource information or the second baseband resource information.
Referring to fig. 2, a flowchart illustrating steps of an embodiment of a baseband resource selection method according to the present invention may specifically include the following steps:
In the embodiment of the invention, in the process of establishing the cell, the polarization directions of all the frequency points in the cell to be established can be configured to be consistent, for example, the polarization directions are configured to be horizontal polarization directions or the polarization directions are configured to be vertical polarization directions. After the polarization directions of all the frequency points in the cell to be established are configured, the polarization directions of the cell to be established are configured, wherein the polarization directions of the cell to be established and the polarization directions of all the frequency points in the cell to be established are the same; for example, if the polarization directions of all the frequency points in the cell to be established are horizontal polarization directions, the polarization directions of the cell to be established are also horizontal polarization directions. Correspondingly, the polarization direction of the cell to be established may be referred to as the polarization attribute of the cell to be established.
After determining the polarization attribute of the cell to be established, configuring matched baseband resources for the cell to be established so as to provide service for the cell to be established; the baseband board is used for selecting the matched baseband board for the cell to be built, so that the matched baseband resource is configured for the cell to be built. In one example of the present invention, when a matched baseband board is selected for the cell to be established, a baseband board having the same polarization attribute as that of the cell to be established may be determined as the baseband board matched with the cell to be established.
In the embodiment of the invention, the baseband board matched with the cell to be established can be searched from the first baseband resource information or the second baseband resource information which are established in advance, and if the search is unsuccessful, the unused baseband board is selected, and then the polarization attribute of the unused baseband board is modified according to the polarization attribute of the cell to be established.

In the embodiment of the present invention, one way to find a baseband board that matches a cell to be established may be to find a baseband board that matches a cell to be established from first baseband resource information. The method comprises the steps of obtaining first baseband resource information which is established in advance, searching a baseband board (which can be called as a first baseband board in the follow-up) matched with a cell to be established from the first baseband resource information according to the polarization attribute of the cell to be established, and determining that the first baseband board is successfully searched if the first baseband board matched with the cell to be established is searched from the first baseband resource information; if the first baseband board matched with the cell to be built is not found from the first baseband resource information, determining that the first baseband board is failed to find, and at the moment, searching the baseband board matched with the cell to be built from the second baseband resource information.
In one example of the present invention, the first baseband resource information may include resource information of a used baseband board and resource information of an associated baseband board of the used baseband board, for example, if the CPB0 board is a used baseband board and the CPB0 board and the CPB1 board are associated baseband boards, the first baseband resource information may include resource information of the CPB0 board and resource information of the CPB1 board. Therefore, according to the resource information of the associated baseband board, such as the polarization attribute information of the associated baseband board, the first baseband board matched with the cell to be established can be searched from the associated baseband board corresponding to the used baseband board in the first baseband resource information.
If the first baseband board is determined to fail to be searched, the second baseband resource information which is established in advance can be obtained, the baseband board (which can be called as a second baseband board in the follow-up) which is matched with the cell to be established is searched from the second baseband resource information according to the polarization attribute of the cell to be established, and if the second baseband board is searched from the second baseband resource information, the second baseband board is determined to be successfully searched; if the second baseband board is not found from the second baseband resource information, determining that the second baseband board is failed to find. The second baseband resource information may include resource information of an unused baseband board, such as polarization attribute information of the unused baseband board, and further may search, according to the resource information of the unused baseband board, a second baseband board that is matched with the cell to be established from the unused baseband board of the first baseband resource information.
If it is determined that searching the second baseband board fails, an unused baseband board may be selected from the second baseband resource information, and then the polarization attribute of the unused baseband board is modified according to the polarization attribute of the cell to be established, for example, the polarization attribute of the unused baseband board may be modified by adjusting the mapping relationship of the IN-OUT port IN the combiner; after modifying the polarization properties, the unused baseband board may be determined as a matching baseband board (which may be referred to as a third baseband board, hereinafter) with the cell to be established.
In summary, in the embodiment of the invention, after determining the polarization attribute of the cell to be established in the process of establishing the cell; first baseband resource information can be acquired, wherein the first baseband resource information comprises resource information of a used baseband board and resource information of an associated baseband board of the used baseband board; then searching a first baseband board matched with the cell to be built from the first baseband resource information according to the polarization attribute of the cell to be built; if the searching of the first baseband board fails, acquiring second baseband resource information, wherein the second baseband resource information comprises resource information of unused baseband boards; searching a second baseband board matched with the cell to be established from the second baseband resource information according to the polarization attribute of the cell to be established; if searching fails from the second baseband resource information, selecting an unused baseband board from the second baseband resource information, modifying the polarization attribute of the unused baseband board according to the polarization attribute of the cell to be established, and determining the unused baseband board after modifying the polarization attribute as a matched third baseband board with the cell to be established. According to the embodiment of the invention, the baseband board matched with the cell to be built is preferentially searched IN the pre-built baseband resource information, and when the search fails from the pre-built baseband resource information, the polarization attribute of the unused baseband board is modified, on one hand, the disorder of the mapping relation of the IN-OUT port caused by directly modifying the polarization direction of the baseband board can be avoided, so that the mapping relation of the IN-OUT port does not need to be readjusted, and the complexity of cell network planning is reduced; on the other hand, compared with the prior art that enough baseband resources are reserved when the network deployment is performed to avoid the occurrence of the abnormality of the baseband board and the baseband resource waste is caused, the baseband board selection mode of the embodiment of the invention is more flexible, and the existing baseband resources can be utilized as much as possible, so that the reserved baseband resources can be as little as possible when the network deployment is performed, and the utilization rate of the baseband resources is improved.
In one example of the present invention, the second baseband resource information may include resource information as shown in the following table 1:

In one example of the present invention, according to the polarization attribute of the cell to be established, a first baseband board having the same polarization attribute as the polarization attribute of the cell to be established may be searched from unused associated baseband boards of the first baseband resource information.
After the matched first baseband board is searched for the cell to be built, the first baseband resource information can be updated each time, for example, the use state information of the first baseband board in the first baseband resource information can be updated to be in a used state, so that the matched baseband board can be conveniently searched for the cell to be built from the first baseband resource information next time.
