Abstract

The invention discloses a data distribution method, device and system. The method includes: receiving a first differential data message sent by a reference station; determining a data format of the first differential data message and a transmission protocol of the first differential data message; according to the data format and the transmission protocol of the first differential data message , verify the first differential data message; when the first differential data message is verified, send the message body to the multicast network device, so that the multicast network device can broadcast the message body to the virtual base station, which improves the data broadcasting flexibility.

Description

technical field [0001] The present invention belongs to the field of communication technologies, and in particular, relates to a data distribution method, device and system. Background technique [0002] At present, the data broadcast protocol in the satellite navigation differential data broadcast system is relatively simple. With the development of the industry, the transmission protocol is constantly updated. During the data broadcast process of the current satellite navigation differential data broadcast system, the differential data uploaded by the base station is aggregated through the differential broadcast platform. Then, the aggregated differential data is broadcast to the terminal device. The terminal equipment and the base station both include at least one. The above data playback methods cannot adapt to different transmission protocols, resulting in low flexibility of data playback. SUMMARY OF THE INVENTION [0003] The embodiments of the present invention p...
