Packet transmission method, system and device for general packet wireless service tunnel protocol

The embodiment of the present invention discloses a general packet radio service (GPRS) tunnel protocol (GTP) message transmission method. The method comprises steps of a first network element packaging more than one GTP message into a same IP datagram by using a multiplex method; The first network element sends the packaged IP datagram to a second network element. The embodiment of the present invention also discloses a GTP message transmission system and a device. By using the method, the system and the device of the present invention, the proportion of effective load data in the IP datagram is improved in the GTP message transmission process.
