Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing:

[0032] Such as figure 1 As shown, an IP data compression transmission method suitable for satellite channels works between the network layer and the data link layer of the satellite IP access gateway network protocol stack. The satellite IP access gateway is located at both ends of the satellite link, and the IP services entering and leaving the IP core network are connected to the satellite communication system through the satellite IP access gateway. The satellite IP access gateway receives the IP data packet from the IP core network, compresses it, sends it to the communication satellite through the uplink, is relayed by the communication satellite, and sends it to the satellite at the other end of the link through the downlink The IP access gateway receives and decompresses the satellite IP access gateway, restores the original IP data packet, and forwards it to the IP...

Abstract

The invention discloses an internet protocol (IP) data compression transmission method applicable to a satellite channel and relates to the technical field of a satellite communication network based on a transmission control protocol (TCP) / IP. IP data packages are compressed to be transmitted on a satellite link. The IP data compression transmission method aims at improving use ratio of satellite channel resources and service access quantity, reducing transmission delay of the IP data packages on the satellite link and enabling the IP data packages to be efficiently and robustly transmitted on the satellite link with high error code, long transmission delay and limited bandwidth resources by compressing the IP data packages to remove redundant data. The method is also applicable to ground cellular mobile communication links and wired and wireless links which are provided with high error code and long transmission delay.

Description

technical field [0001] The invention discloses an IP data compression transmission method suitable for satellite channels, relates to the technical field of satellite communication networks based on TCP / IP, and in particular relates to an IP data compression transmission method suitable for satellite channels. transmission over satellite links. The method disclosed by the invention is also applicable to ground cellular mobile communication links and other wired and wireless links with high bit error and long transmission time delay. Background technique [0002] At present, the transmission of IP services in the satellite communication network has been more and more widely used. Compared with the traditional circuit multiplexing access method, the advantages of using IP service access in the satellite communication network are that various services are conveniently accessed, flexible networking, and strong versatility; the disadvantage is that the service data is transmitte...
