step two: the combining single board automatically configures the carrier wave responding to the RRU on the current connection to complete the carrier wave configuration of all the RRUs on the current connection;
step three: the combining single board automatically configures a new access RRU (NEW RRU), and feeds back various connection information and state information of the new access RRU to the BBU.
In the existing general base station system, when a plurality of RRUs converge to a BBU to form a logical cell, data of the plurality of RRUs need to converge to a single combining board for processing and then transmit the processed data to the BBU. The carrier configuration information of the RRUs needs to be sequentially transmitted downwards by the BBU until the corresponding RRUs, and the RRUs newly accessing the network can not correctly transmit the carrier configuration information to the RRUs after configuring various information and routing information on the BBU.
The invention configures the carrier information to the combining single board, automatically configures the RRU by the combining single board, reports the actual configuration result information to the BBU after being identified by the combining single board, and simultaneously supports the automatic configuration of the new RRU, thereby reducing various information of manually configuring the RRU, reducing the operation and maintenance cost and realizing the availability of the RRU access.

In this embodiment, as shown in fig. 2, in a general base station system, when a plurality of RRUs converge to a BBU to form a logical cell, data of the plurality of RRUs need to be converged to a single combining board for processing and then transmitted to the BBU. The carrier configuration information of the RRUs needs to be sequentially transmitted from the BBU to the corresponding RRUs, and the RRUs newly accessing the network also needs to configure various information and routing information on the BBU before correctly transmitting the carrier configuration information to the RRUs.
The invention configures the carrier information to the combining single board, automatically configures the RRU by the combining single board, reports the actual configuration result information to the BBU after being identified by the combining single board, and supports the automatic configuration of the new RRU, thereby reducing various information of manually configuring the RRU, reducing the operation and maintenance cost and realizing the availability of the RRU access.

If the automatic switch is closed, the automatic configuration process is finished. The physical capabilities include frequency bands supported by the RRU, the number of antennas, the power range, and the like.
2. And after collecting the software and hardware capabilities, the RRU sends a query response to the combining single board.
3. And after receiving the capability transmitted by the RRU, the combining single board matches the general information transmitted by the BBU to see whether the general information is matched, if so, the step 4.A is carried out, and if not, the step 4.B is carried out.
