Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 What is shown is a method for transmitting data packets provided by an embodiment of the present invention. Wherein, the data packet includes a general header and at least one data block, and the data block includes a data block header; the above-mentioned data packet can be an SCTP data packet based on the SCTP protocol, or it can be another SCTP data packet similar to the SCTP data packet with general Packet headers and data packets that transmit multiple steams (streams) in different data blocks.

[0026] The methods of transmitting packets include:

[0027] Step 101, the first endpoint sends an initialization message to the second endpoint, the initialization message includes: packet header c...

Abstract

The embodiment of the invention discloses a method and device for transmitting data packets, wherein the method comprises the steps: a first end point sends an initialization message to a second end point, wherein the initialization message comprises packet header compression algorithm information and identifications of data blocks in data packets, and each identification of the data block comprises an identification of a data block with a data block packet header needed to be compressed; the first end point compresses the data packets, wherein compression process comprises the steps of compressing the data block packet header needing to be compressed in the data packets by using the packet header compression algorithm indicated by packet header compression algorithm information; and the first end point sends the compressed data packet to the second end point so as to reduce the extra cost of the packet header in a wireless air interface transmission protocol and the consumption of transmission resources.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for transmitting data packets. Background technique [0002] Relay (relay) technology is to increase the distribution density of stations and antennas by adding some new relay stations (or relay nodes) on the basis of the original stations. These new relay nodes and the original base station (mother base station) are connected wirelessly, and there is no wired connection with the transmission network. The downlink data first arrives at the mother base station, and then is transmitted to the relay node, and then transmitted to the relay node. End users, and vice versa for uplink. This method shortens the distance between the antenna and the terminal user, which can improve the link quality of the terminal, thereby increasing the spectrum efficiency and user data rate of the system. [0003] In the existing Relay architecture scenario, SCTP (Stream Contro...
