Abstract
The present invention discloses a method and an apparatus for compressing and decompressing an IP data packet. The method includes: performing, by a first device, compression processing on IP data in an IP data packet according to a first compression algorithm; and encapsulating, by the first device, the IP data after the compression processing into a packet data convergence protocol (PDCP) data packet, where header information of the PDCP data packet includes identifier information, where the identifier information is used to indicate the first compression algorithm or indicate that the IP data is compressed.
