A method, system and apparatus for transmitting data are disclosed, which are applied in the network with separation of identity identifiers and position identifiers. The method includes: a source terminal (31) transmits a first packet (301) to a source Access Service Node (ASN) (32) while taking the Access Identifier (AID) of the source terminal and the AID of a target terminal (36) as the source address and the target address of the first packet, respectively; after receiving the first packet, the source ASN encapsulates the first packet into a second packet by use of a Generic Routing Encapsulation (GRE) format if the Routing Identifier (RID) corresponding to the AID of the target terminal can not be queried locally; the source ASN transmits the second packet (303) to a mapping and forwarding plane, which queries the RID corresponding to the AID of the target terminal and transmits the first packet to a target ASN (35) based on the queried RID. |
