Abstract
The invention relates to a large-capacity high-speed Beidou data transmission method and a large-capacity high-speed Beidou transmission system. The large-capacity high-speed Beidou transmission system comprises a target Beidou user terminal, a forwarding Beidou terminal array, a forwarding server and a data transmission request client. The target Beidou user terminal is data receiving party Beidou equipment and comprises a Beidou handheld machine, a Beidou all-in-one machine, a Beidou command machine and other equipment with a Beidou short message transceiving function. The forwarding Beidou terminal array is composed of common Beidou terminals and is connected with the forwarding server for forwarding data which are pushed by the forwarding server. The forwarding server is used for managing a Beidou forwarding array and processing the data transmission request of the client. The data transmission request client is a data transmission request party and is connected with the server for pushing to-be-transmitted data and performs transmission by the forwarding server through the forwarding Beidou terminal array. According to the large-capacity high-speed Beidou data transmission method and the large-capacity high-speed Beidou data transmission system, data are forwarded by means of the Beidou terminal array, and limitation by Beidou message communication service frequency and data length can be well broken.
Description
Technical field
