The first device may comprise, e.g., an operator terminal. The message may comprise a uniform resource locator (URL), and may additionally identify a software application residing on the second device. The message may also include one or more parameters used to provide the requested service. The command is retrieved from the message, and the command is transmitted to the second device, thereby causing the second device to provide the service.
