Abstract

The invention provides a scheduling method for dynamic access of an Internet of things terminal, which constructs a fine scheduling view angle for an intersection area based on periodic resource use information and intersection area edge terminal equipment information, and can dig out idle fragments which can be cooperatively utilized from time and resource dimensions under the condition that two micro base stations are busy at the same time, so as to schedule a priority access opportunity and a stable transmission channel for the edge terminal, thereby effectively avoiding the problem that the intersection area terminal cannot build a link or frequently drops in a long term. Through dynamic network interconnection and complementary scheduling, the preemption and mutual interference of two micro base stations to the same time-frequency resource in a crossing area are reduced, the rate reduction, time delay and jitter deterioration phenomena caused by random access conflict and backhaul link congestion are relieved, and the Internet of things terminal obtains higher access success rate and service continuity in crowd intensive scenes such as large-scale business superelevation, amusement parks and the like, so that the overall stability of an indoor network and the service quality of an edge area are obviously improved.
