Abstract
In one embodiment, the method includes encrypting, at a device, data with a first key, and forming a message that includes a device identifier and the encrypted data. The device identifier identifies the device. A signaling message is formed that includes a class identifier, the message and an action code. The class identifier identifies a group of devices to which one or more devices belong. The action code indicates the type of data, and may be part of the message. The signaling message is sent to a network, for example, a wireless network. The wireless network identifies and routes the message portion of the signaling message based on the class identifier. And, using the class identifier and perhaps a device identifier, the wireless network may signal the device to change an operating parameter.
