Example configuration methods and apparatus are described. In one example method, a first baseband unit (BBU) updates a first line rate, and sends a data frame to the second BBU at an updated first line rate after each update. The first BBU receives a data frame that is sent by the second BBU at an updated second line rate after each time the second BBU updates a second line rate. When the first line rate is equal to the second line rate, the first BBU sends networking relationship information of the first BBU to the second BBU at the first line rate, and receives networking relationship information of the second BBU that is sent by the second BBU at the second line rate. The first BBU establishes a bidirectional upper-layer communication channel with the second BBU based on a communication address of the second BBU allocated by the first BBU.

Integrated access system, configuration method, and baseband unit

Example integrated access systems, configuration methods, and baseband units are described. One example integrated access system includes a first baseband unit (BBU), a second BBU, a first data exchange unit, a first base station network management subsystem, a second base station network management subsystem, and a first pico remote radio unit (pRRU). The first BBU is connected to the first data exchange unit, the first BBU is connected to the first base station network management subsystem, the first BBU is connected to the second BBU, the second BBU is connected to the second base station network management subsystem, and the first pRRU is connected to the first data exchange unit.
