Embodiment Construction

[0023] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] In the prior art, the GTP protocol may include a GTP control plane (GTP Control plane, GTP-C) protocol, a GTP user plane (GTP User plane, GTP-U) protocol, and a charging-related GTP' protocol. Among them, GTP-C is used to create, modify and delete tunnels; GTP-U is used to carry user data packets.

[0025] As shown in Table 1, the GTP header format is applicable to both GTP-C and GTP-U, with a variable length and a minimum length of 8 bytes. Among them, there are 3 marks used to indicate whether there is an optional part: E mark, S mark and PN mark. The E flag is used to indicate whether there is an extended header field, the S flag is used to indicate whether there is a sequence number, and the PN flag is used to indicate whether there is an N...

Abstract

The invention discloses a method for transmitting GTP data packets of a GPRS tunneling protocol, which comprises the following steps: multiplexing a plurality of the G-PDU packets together on a sending endpoint of a GTP tunnel, and sending the G-PDU packets to a receiving endpoint of the GTP tunnel after packing the together multiplexed G-PDU packets through the transmission path protocol. With the technical proposal of the invention, the transmission efficiency can be improved, and the transmission bandwidth can be saved, simultaneously, the number of the transferred data packets in the transmission network further can be reduced, and the load of the transmission network can be reduced, and simultaneously, the invention further discloses a GTP tunnel endpoint device.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and equipment for transmitting general packet radio service (General Packet Radio Service, GPRS) tunneling protocol data packets. Background technique [0002] The Universal Mobile Telecommunication System (Universal Mobile Telecommunication System, UMTS) / GPRS backbone network composed of the Gateway GPRS Support Node (GGSN) and the Serving GPRS Support Node (SGSN), adopts the GPRS tunneling protocol ( GPRS Tunneling Protocol, GTP) transmits user packet data; transmits tunnel management information related to tunnel establishment, maintenance, and release; transmits path management information related to response requests, response responses, and versions not supported. The GGSN and the SGSN may be collectively referred to as a GPRS Support Node (GPRS Support Node, GSN). A variety of data can be encapsulated by using the GTP tunnel, so that the GPRS...
