  • Protocol conversion method and apparatus
    Patent number: 10523791
    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.
