Abstract: This application provides a data packet processing method and apparatus, applied to a satellite communications system. An earth surface, space, and network space are divided based on a satellite constellation and an ephemeris of a satellite, and an identifier is allocated to each ground area, each space area, and each network that are sub-divisions of the earth surface, space and network space, to establish a fixed mapping relationship between the EID, the SID, and the NID. In addition, each satellite maintains mapping relationship information recording the mapping relationship. Unless a satellite joins the constellation or one satellite leave service, the mapping relationship recorded in the mapping relationship information does not need to be updated. Based on the mapping relationship information, a satellite may route a data packet, thereby reducing a large amount of signaling interaction caused by establishing and maintaining a routing table in the conventional manner.
