INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A server application executing on the public Internet may establish or re-establish a packet data network (PDN) connection with a client application executing on mobile device over a cellular network by initiating a telephone call to the mobile device via a cellular access network node according to a telephone number associated with the client application. The mobile device may receive a paging for the telephone call from the cellular access network node. In response to the paging, the mobile device may determine a PDN communication channel associated with the server application, the PDN including the cellular access network node, and send a set of data to the server application via the determined PDN communication channel. The server application may, in response to receiving the set of data, send a second data set of data to the client application over a PDN communication channel associated with the client application. ## Claims ### Claim 1 An apparatus of an application server, the apparatus comprising memory; and processing circuitry coupled to the memory, the processing circuitry configured to: determine a telephone number associated with a client application executing on a user equipment (UE) and store the telephone number in the memory;
