Abstract: A data transmission system and method thereof for edge computing are provided. A terminal mobile station international subscriber directory number (MSISDN) and a terminal IP of a target terminal are obtained with a domain name system (DNS) by a device providing communication services from the data transmission system. After data packets are sent to the data transmission system, if the target terminal is in an idle mode, a paging message is sent by a terminal wake-up module to enable the target terminal to return to a connected mode for communication. Before a connection is established between the data transmission system and the target terminal, downlink data packets can be temporarily stored, and the packets can be sent after the target terminal is in the connected mode. A computer readable medium for executing the data transmission method is also provided.

Abstract: A light source reflector includes a conical reflective surface, and a flat reflective surface formed on a rim of the conical reflective surface. The conical reflective surface has a plurality of unit curved surfaces with convex surfaces or concave surfaces. Also, the flat reflective surface is provided with a plurality of refraction protrusions, to improve the optical efficiency and light-mixing effect of the light source reflector.
