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: The present invention is directed to a metal air electrochemical cell whereby the anode is encapsulated with a protective layer. The encapsulated metal air anode provides prolonged submersion of anodes in electrolyte, improved metal anode discharge and decreased metal anode corrosion.

Abstract: Herein provided are polyelectrolyte membranes that block dendrite growth in rechargeable batteries, possess low inherent electrical resistance to be used as separators, possess high ionic conductivities, and block fuel crossover in direct fuel feeding fuel cells. Further provided are cost-effective processes for forming polyelectrolyte membranes. The herein described polyelectrolyte membranes are useful in electrochemical cells such as primary batteries, secondary batteries such as Ag—Zn, Ni—Zn, Ni-MH, Li polymer, and Li-ion; fuel cells including but not limited to metal air battery or fuel cells, proton exchange membrane hydrogen fuel cells, direct liquid feed fuel cell.
