Satellite communication and satellite television signal IP fusion relay method based on decoding and forwarding

Abstract

The invention discloses a satellite communication and satellite television signal IP fusion relay method based on decoding and forwarding. A satellite communication and satellite television signal IP fusion relay device comprises a satellite signal access unit, a satellite communication signal access unit, a relay unit and a terminal unit. The satellite television signal access unit and the satellite television communication signal access unit are connected with the relay unit through the switch; the working mode of the method is explained in detail. The method has the following effects: 1, compared with a transparent forwarding scheme, the method can obviously improve the relay effect of the satellite signal; 2, the satellite television signals are relayed through a decoding and forwarding method based on the LTE technology, and the satellite television signals can be deeply fused with a satellite communication signal relaying scheme realized based on the LTE decoding and forwarding method; 3, the satellite television and the satellite communication signals are relayed through a decoding and forwarding method based on the LTE technology; when the tunnel relay equipment of the ground mobile network exists in the tunnel area, the putting amount of new equipment can be reduced, so that the access cost of the satellite network in the area covered by the existing ground mobile network is further reduced, and the waste of public resources is reduced.

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
