Abstract: This application provides a base station function deployment method and device. The base station includes at least a first radio center system RCS and a first radio remote system RRS. The method includes: obtaining a selected split manner that matches an available transmission resource between the first RRS and the first RCS, where the selected split manner is used to split functions of the base station into a first function group and a second function group; and deploying, on the first RCS, a base station function that is included in the first function group and that is determined based on the selected split manner, and deploying, on the first RRS, a base station function that is included in the second function group and that is determined based on the selected split manner.

Abstract: Embodiments of the present invention provide a protocol conversion method and apparatus. The method includes: implementing frequency synchronization and time synchronization with a baseband unit (BBU) using an Ethernet protocol; obtaining frequency synchronization information and time synchronization information in a first format from an Ethernet interface; converting the frequency synchronization information and the time synchronization information in the first format into frequency synchronization information and time synchronization information that are in a second format, where the second format is a common public radio interface CPRI protocol format; and sending the frequency synchronization information and time synchronization information in the second format to a remote radio unit (RRU) using a CPRI interface, where the RRU supports a CPRI protocol.

Abstract: Embodiments of the present disclosure relate to a method and an apparatus for probing a fronthaul topology. The method includes: sending, by a baseband device, a source route probe frame; receiving a destination route probe frame, where the destination route probe frame is formed after a first transport network device records first port information in the source route probe frame and a second transport network device records second port information in the source route probe frame; and determining, by the baseband device, probe information according to the destination route probe frame, and sending the probe information to an element management system EMS.
