Super-large scale VSAT system frame structure and resource allocation method

Abstract

The invention relates to a super-large scale VSAT system frame structure and a resource allocation method. As for a large-scale broadband satellite communication network formed by integrating a VSAT system and other external networks, a signaling interactive process in integration of the VSAT system and the external networks is considered, and control signals are transmitted in different modes for adequate original frequency band resources and inadequate original frequency band resources; when the resources are adequate, signaling time slots are divided from service time slots and used for signaling interaction between small stations of the VSAT system and the external networks; when the resources are inadequate, dedicated frequency bands divided from wireless resources are increased, and unit time slots of the dedicated frequency bands are used for signaling interaction between the small stations of the VSAT system and the external networks; wasting of resources is avoided, system capacity is improved, transmission efficiency of the system is further promoted, and timeliness and stability of transmission of the control signals under the circumstance that the large-scale small stations have access to the system are guaranteed.

Description

technical field [0001] The invention relates to a super-large-scale VSAT system frame structure and a resource allocation method, belonging to the technical field of satellite communication. Background technique [0002] At present, the small-scale VSAT (Very Small Aperture Terminal) system technology is very mature, and with the broadband of the network and the diversification of business requirements, the satellite communication system can carry a variety of multimedia services, such as video conferencing, VoIP, video Talking, Web browsing, FTP downloading, etc., the VSAT satellite communication system is developing from a traditional small-scale narrowband data communication application to a large-scale broadband multi-service satellite network integrating telecommunications, broadcasting, and computers. Therefore, the combination technology of satellite and ground system will be paid more attention and will be widely used. [0003] The DVB-RCS protocol stipulates the co...

Problems solved by technology

Moreover, the current design of the VSAT system frame structure is only for the traditional VSAT system, and does not consider the time slot division of the interactive control signaling when the VSAT system is interconnected with other networks. The interactive signaling bytes are small. When the system scale When it is increased, if the traditional business time slot is used to transmit interactive control signaling, resources will be wasted, the system capacity will be reduced, and the transmission efficiency will be reduced.
