The CPB board may be connected to the IN port of the combining 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 of the CPB board (hereinafter referred to as polarization property).
One IN port IN the combining matrix can be connected with one CPB board or a plurality of CPB boards; when one IN port is connected with a plurality of CPB boards, different CPB boards connected to the same IN port may be associated baseband boards with each other, and any one of the CPB boards may be referred to as an associated baseband board corresponding to the other CPB boards; for example, if both the CPB0 board and the CPB1 board are connected to the 1IN port, the CPB0 board and the CPB1 board may be associated baseband boards with each other, and the CPB0 board is an associated baseband board corresponding to the CPB1 board.
IN an example of the present invention, after determining the polarization attribute of the CPB board according to the baseband resource system, the resource information of the CPB board (for example, the polarization attribute of the CPB board, the record number associated with the CPB, and the information of the IN port and the OUT port of the combining matrix, the use state, and the like) may be reported to the GSC IN advance; then, the GSC may generate first baseband resource information, such as the baseband resource information pool a, according to the resource information of the used CPB board and the resource information of the associated CPB board corresponding to the used CPB board. The GSC may also generate second baseband resource information, such as a baseband resource information pool B, according to the resource information of the unused CPB board.

Referring to fig. 2, a flowchart illustrating steps of an embodiment of a baseband resource selection method according to the present invention is shown, which may specifically include the following steps:
In the embodiment of the present invention, in the process of establishing a cell, the polarization directions of all frequency points in the cell to be established may be configured to be the same, for example, all the polarization directions are configured to be horizontal polarization directions or all the polarization directions are configured to be vertical polarization directions. After the polarization directions of all frequency points in the cell to be established are configured, the polarization direction of the cell to be established is configured, wherein the polarization direction of the cell to be established is the same as the polarization directions of all frequency points in the cell to be established; for example, if the polarization directions of all frequency points in the cell to be established are horizontal polarization directions, the polarization direction of the cell to be established is also the horizontal polarization direction. Correspondingly, the polarization direction of the cell to be established may be referred to as the polarization property 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 to provide service for the cell to be established; and the matched baseband resource can be configured for the cell to be established by selecting the matched baseband board for the cell to be established. In an example of the present invention, when selecting a matching baseband board for the cell to be established, a baseband board having the same polarization property as that of the cell to be established may be determined as the baseband board matching 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 pre-established first baseband resource information or second baseband resource information, if the baseband board is not successfully searched, the unused baseband board is selected, and 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 search for the baseband board matched with the cell to be established may be to first search for the baseband board matched with the cell to be established from the first baseband resource information. Further, pre-established first baseband resource information can be acquired, then a baseband board (which may be referred to as a first baseband board in the following process) matched with the cell to be established is searched from the first baseband resource information according to the polarization attribute of the cell to be established, and if the first baseband board matched with the cell to be established is searched from the first baseband resource information, it is determined that the first baseband board is successfully searched; if the first baseband board matched with the cell to be established is not found from the first baseband resource information, it is determined that finding the first baseband board fails, and at this time, the baseband board matched with the cell to be established can be found from the second baseband resource information.
In an 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 the used baseband board and the CPB0 board and the CPB1 board are associated with each other, 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 property 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 it is determined that the search for the first baseband board fails, second baseband resource information which is established in advance can be obtained, a baseband board (which may be subsequently referred to as a second baseband board) 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 search for the second baseband board is determined to be successful; and if the second baseband board is not searched from the second baseband resource information, determining that the second baseband board is searched unsuccessfully. 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, a second baseband board matched with the cell to be established may be searched from the unused baseband board of the first baseband resource information according to the resource information of the unused baseband board.
If it is determined that finding the second baseband board fails, selecting an unused baseband board from the second baseband resource information, and then modifying the polarization attribute of the unused baseband board according to the polarization attribute of the cell to be established, for example, modifying the polarization attribute of the unused baseband board by adjusting a mapping relationship of an IN-OUT port IN a combining device; after the polarization property is modified, the unused baseband board may be determined as a matched baseband board (which may be referred to as a third baseband board hereinafter) with the cell to be established.
To sum up, in the cell establishment process, the polarization attribute of the cell to be established is determined; 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, according to the polarization attribute of the cell to be established, searching a first baseband board matched with the cell to be established from the first baseband resource information; if the first baseband board is searched for unsuccessfully, second baseband resource information is obtained, wherein the second baseband resource information comprises resource information of unused baseband boards; according to the polarization attribute of the cell to be established, searching a second baseband board matched with the cell to be established from the second baseband resource information; if the search from the second baseband resource information fails, 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 the polarization attribute is modified as a third 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 is preferentially searched IN the pre-established baseband resource information, and the polarization property of the unused baseband board is modified when the search fails IN the pre-established baseband resource information, so that 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, the mapping relation of the IN-OUT port does not need to be re-adjusted, and the complexity of cell network planning is reduced; on the other hand, compared with the prior art that enough baseband resources are reserved during network deployment to avoid baseband board abnormity, the baseband board selection method of the embodiment of the invention is more flexible and can utilize the existing baseband resources as much as possible, so that the baseband resources can be reserved as little as possible during network deployment, thereby improving the utilization rate of the baseband resources.

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