Abstract

The invention discloses a response method of an Internet of Things data packet in an intelligent building. The method comprises the following steps: calculating the delay amount delta W1 of each destination TP address, wherein delta W1 is equal to tint * W1 / Min (W1); wherein Min (W1) refers to selecting the minimum value of all W1; calculating the correction arrival time t '= t + delta t of each data packet; wherein t is the actual time when the data packet reaches the access gateway; and sending the data packets to the Internet of Things terminal in sequence according to the sequence of the corrected arrival time. According to the load condition of gateway equipment, different processing strategies are provided for the response data packet, when the load is large, targeted flow control can be performed on different destination IPs, and the flow control considers the requirements of the frequency and the service type of the response data packet for the data packet processing timeliness, so that the data packet processing efficiency is improved. The interval delay degree calculated by the delay control algorithm is at the same number level as the average time interval, and the tolerance of the terminal to the response message delay can be reflected.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a response method for an Internet of Things data packet in an intelligent building. Background technique [0002] With the rapid development of communication technology and the further integration of communication technology and Internet technology, the penetration rate of mobile services and mobile Internet technology is getting higher and higher. At present, in most developed countries, the penetration rate of mobile communication even reaches 100%, which leads to slower and slower growth of mobile users, and the global mobile operators basically face this problem. For this reason, operators began to look for new growth points in the field of mobile communications. On the other hand, with the rise of Internet technology, especially the rise of mobile Internet technology resulting from the integration of Internet technology and mobile communication technology, a new door...
