One or more embodiments relate generally to providing power management services or a power management server to endpoint devices in a local network (e.g., a home network) from a cloud based computing environment. One embodiment provides power management through cloud based services.
In one embodiment, the endpoint electronic devices may comprise a mobile electronic device capable of data communication over a communication link such as a wireless communication link. Examples of such mobile device include a mobile phone device, a mobile tablet device, smart mobile devices, etc.
In one embodiment, a method provides power management that comprises registering and subscribing one or more endpoint devices to a remote power management service. In one embodiment, the one or more endpoint devices are connected with a local network. In one embodiment, power state information of the one or more endpoint devices is obtained. In one embodiment, power state of one or more endpoint devices is changed using the remote power management service.
One or more embodiments provide power management for local (e.g., home) network devices with the use of a cloud-based service that provides processing in the cloud and at the same time provides a mechanism to minimize power consumption in the devices. In one or more embodiments, providing the cloud-based service for power management removes the dependence for a low power proxy device in the home network in order for the low power devices to enter low power state, or be awakened from a sleep state or mode. One embodiment provides mechanism for devices in the home network to convey power state information to a device or service external to the home network, and provides a mechanism for a device in the home network to receive information about devices that are available in the home network from the cloud but are not advertising themselves in the home network (e.g., the devices are currently in sleep state or mode). One embodiment provides a mechanism for a service or device in the cloud to change the power state of a device in the home network.

FIG. 4 shows another example scenario 400 for the power (management) service 170 provided via the cloud 160 to the local network 150, according to an embodiment. In one embodiment, remote devices, such as mobile devices, may access the local network 150 through a medium (e.g., Internet 420) while endpoint devices on the local network 150 may be in a low power state or mode. In one embodiment, a mobile device 120 uses the Internet 420 to access a gateway 410 for the local network 150. In one embodiment, mobile devices may use remote access techniques, for example, digital living network alliance (DLNA) remote access guidelines, virtual private network (VPN), etc., to become part of the local network 150.
In one embodiment, the remote access device 120 must support UPnP lower power and include the capability to access the power service 170 in the cloud 160, just as the local network 150 endpoint devices are required to support. In one embodiment, the remote device 120 may discover and wake up the local network 150 endpoint devices just as if it were physically on the local network 150.

In one embodiment, the network servers 950 may be servers operated by any of a wide variety of network providers and generally comprise servers that store information about electronic devices that are connected to one another by one or more user interdependencies (e.g., friends, business relationship, family, and the like). Although some of the electronic device information stored by a network server is private, some portion of the information may be public information (e.g., a basic profile of the user that includes a user's name, picture, and general information). Additionally, in some instances, a user's private information may be accessed by using the user's login and password information. The information available from a user's network account may be expansive and may include one or more lists of friends, current location information (e.g., whether the user has “checked in” to a particular locale), etc. Depending on the privacy setting established by the user, at least some of this information may be available publicly. In one embodiment, a user's private or public network information may be searched and accessed by communicating with the network server 950, using an application programming interface (“API”) provided by the network operator.
In one embodiment, the low power management controller 940 performs operations associated with a low power management application or method. In one example embodiment, the low power management controller 940 may receive device information from a plurality of electronic devices (or just from one local electronic device), determine relationships between two or more of the electronic devices, and transmit low power information to one or more electronic devices or low power management services based on the determined relationships.
In one embodiment, the low power management controller 940 need not be implemented by a remote server, as any one or more of the operations performed by the low power management controller 940 may be performed in another distributed computing environment (e.g., a cloud computing environment).

One or more embodiments may use features of WebRTC for acquiring and communicating streaming data. In one embodiment, the use of WebRTC implements one or more of the following APIs: MediaStream (e.g., to get access to data streams, such as from the user's camera and microphone), RTCPeerConnection (e.g., audio or video calling, with facilities for encryption and bandwidth management), RTCDataChannel (e.g., for peer-to-peer communication of generic data), etc.
In one embodiment, the MediaStream API represents synchronized streams of media. For example, a stream taken from camera and microphone input may have synchronized video and audio tracks. One or more embodiments may implement an RTCPeerConnection API to communicate streaming data between browsers (e.g., peers), but also use signaling (e.g., messaging protocol, such as SIP or XMPP, and any appropriate duplex (two-way) communication channel) to coordinate communication and to send control messages. In one embodiment, signaling is used to exchange three types of information: session control messages (e.g., to initialize or close communication and report errors), network configuration (e.g., a computer's IP address and port information), and media capabilities (e.g., what codecs and resolutions may be handled by the browser and the browser it wants to communicate with).
In one embodiment, the RTCPeerConnection API is the WebRTC component that handles stable and efficient communication of streaming data between peers. In one embodiment, an implementation establishes a channel for communication using an API, such as by the following processes: client A generates a unique ID, Client A requests a Channel token from the App Engine app, passing its ID, App Engine app requests a channel and a token for the client's ID from the Channel API, App sends the token to Client A, Client A opens a socket and listens on the channel set up on the server. In one embodiment, an implementation sends a message by the following processes: Client B makes a POST request to the App Engine app with an update, the App Engine app passes a request to the channel, the channel carries a message to Client A, and Client A's on message callback is called.
In one embodiment, WebRTC may be implemented for a one-to-one communication, or with multiple peers each communicating with each other directly, peer-to-peer, or via a centralized server. In one embodiment, Gateway servers may enable a WebRTC app running on a browser to interact with electronic devices.
In one embodiment, the RTCDataChannel API is implemented to enable peer-to-peer exchange of arbitrary data, with low latency and high throughput. In one or more embodiments, WebRTC may be used for leveraging of RTCPeerConnection API session setup, multiple simultaneous channels, with prioritization, reliable and unreliable delivery semantics, built-in security (DTLS), and congestion control, and ability to use with or without audio or video.
