A method for processing a Data Record Packet includes: a General Packet Radio Service Supported Node (GSN) sends a Data Record Packet to a Charging Gateway Function (CGF), wherein the Data Record Packet is a normal packet or a possibly duplicated packet, and the message header of a message for sending Data Record Packet includes a sequence number and the message body includes packaging time; and the CGF sends a response message of receiving the Data Record Packet to the GSN, wherein the Packet Transfer Response Command information element in the response message is used to indicate whether the response message is for the normal packet or the possibly duplicated packet. Therefore, the problem that possibly duplicated packets occupy sequence number resources is solved without limiting the network transmission speed.
