Abstract

The present application provides a data extraction method and apparatus for extracting data to be extracted in the uplink direction of a physical layer field programmable gate array (FPGA) of a base station subsystem, wherein the data to be extracted includes ingress data or egress data. The method comprises: configuring parameter information of the data to be extracted, wherein the parameter information includes: an optical port number, a first subframe number, a first symbol, a first antenna number, and a first physical resource block number, wherein the optical port number includes the ingress number or egress number of the data to be extracted; comparing the packet header format of the basic frame data of the optical port number with the parameter information; if the comparison result is a match, extracting the ingress data or egress data that matches the parameter information and writing the extracted data to a random access memory; and reading the extracted uplink data from the random access memory by polling a high-speed serial computer expansion bus standard PCIE interface. The present application can improve the efficiency of abnormal location in base station systems.
