Satellite communication and satellite TV signal ip fusion relay method based on decoding and forwarding

Abstract

The invention discloses a satellite communication and satellite TV signal IP fusion relay method based on decoding and forwarding, including a satellite TV signal access unit, a satellite communication signal access unit, a relay unit and a terminal unit; a satellite TV signal access unit and a satellite communication signal The access unit is connected to the relay unit through a switch; its working method is specified in this method. The effects of the present invention are: 1. Compared with the transparent forwarding scheme, the effect of satellite TV signal relay can be significantly improved; 2. The satellite TV signal is relayed by the decoding and forwarding method based on LTE technology, which can be compared with the LTE decoding and forwarding method. The satellite communication signal relay scheme is more deeply integrated; 3. Both satellite TV and satellite communication signals are relayed through the decoding and forwarding method based on LTE technology. When there is already a tunnel relay equipment for the ground mobile network in the tunnel area, new equipment can be reduced In order to further reduce the access cost of the satellite network in the area covered by the ground mobile network, and reduce the waste of public resources.

Description

technical field [0001] The invention relates to a satellite communication and satellite TV signal IP fusion relay method based on decoding and forwarding. Background technique [0002] High-speed rail has become our most common way of travel. By 2025, my country's high-speed rail mileage will reach 38,000 kilometers. At present, the high-speed rail mobile Internet system that can greatly improve the passenger experience is mainly implemented based on the ground mobile network, while the high-speed rail mobile Internet system based on satellite communication has no mature application cases. [0003] In the high-speed rail mobile Internet system based on the ground mobile network, there are disadvantages such as high network construction costs (a base station needs to be built every few hundred meters), frequent cell switching, and complicated network optimization. In terms of network coverage, in the vast central and western regions or mountainous areas, the urban density is...

Problems solved by technology

Through the above research content, it is found that the relay technology based on DVB-S / S2 itself is seriously affected by multipath, although the introduction of DVB-RCS / T (Digital Video Broadcasting-Return Channel via Satellite / Terrestrial) technology can partially solve this problem, but these studies only exist at the simulation level, and there is no physical display
