MULTIPLE ACCESS METHOD, DEVICE AND SYSTEM

摘要

Provided are a multiple access method, device and system. The method includes: a network device receiving a packet, the packet including identification information about a terminal; according to the identification information about the terminal, querying a correlation table of terminal identification information and broadcast channels, and determining a broadcast channel corresponding to the identification information about the terminal, the determined broadcast channel being one broadcast channel in a plurality of preset broadcast channels, and the terminal being any terminal in a terminal group corresponding to the determined broadcast channel; and according to the identification information about the terminal, through the determined broadcast channel, sending the packet to the terminal, so that the terminal uses a modulation parameter of the determined broadcast channel to demodulate the packet, increasing the relatively low efficiency of resource utilization and reducing signalling overheads.
