Abstract: A communications system, a communication method and apparatus, where the communications system includes a client, a first resource server and a centralized redirector. The client is configured to send, to the first resource server, a first request packet including a first resource identifier to request resource information corresponding to the first resource identifier. The first resource server is configured to send, to the centralized redirector, a second request packet including the first resource identifier when the resource information corresponding to the first resource identifier is not stored. The centralized redirector is configured to send to the first resource server based on mapping information, a second response packet. The first resource server is further configured to obtain, using the second resource server, the resource information and send a first response packet to the client.

Abstract: An Internet of Things data transmission method includes sending, by a terminal device, a first data request to a server, and continuously receiving, by the terminal device, N data packets from the server. The first data request instructs the server to continuously send a plurality of data packets. The first data request includes a quantity N of data packets, that the terminal device is capable of continuously receiving, and a time interval for sending two consecutive data packets, where N is an integer greater than 1. The N data packets include at least one non-confirmable Constrained Application Protocol (NON) data packet, a sending time interval between two consecutive data packets in the N data packets and the at least one NON data packet indicates that sending a receiving response from the terminal device to the server is unnecessary.
