Abstract: A data routing method used to implement data routing in a communications system in which a plurality of networks that use different data bearer protocols are integrated is produced. The method includes: a routing apparatus receives data by using an input port, and determines a data bearer protocol attribute of the input port; the routing apparatus determines an attribute of the data based on the data bearer protocol attribute of the input port; the routing apparatus determines based on the attribute of the data, a data bearer protocol attribute of an output port used to output the data; and determines based on the data bearer protocol attribute of the output port, the output port used to output the data, and outputting the data by using the determined output port.

Abstract: An integrated access system, comprising a first baseband unit (BBU), a remote common public radio interface (CPRI) data exchange unit connected to the first BBU by a first CPRI channel, a first radio frequency card (RFC) board on a socket of the first BBU, a repeater network management object function module, and a base station network management subsystem including the repeater network management object function module and connected to the first BBU by using an operation management (OM) channel. The first RFC board includes a digital up- and down-frequency conversion module, a digital combination and division module connected to the digital up- and down-frequency conversion module, and a CPRI compression and decompression module, and the digital combination and division module is connected to the CPRI compression and decompression module. The first BBU includes a CPRI mapping and demapping module connected to the CPRI compression and decompression module.

Abstract: 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.
