ISO/IEC 29341-16-11:2011 PDF

Overview

ISO/IEC 29341-16-11:2011 - "Information technology - UPnP Device Architecture - Part 16-11: Low Power Device Control Protocol - Low Power Service" defines a UPnP service for communicating and managing device power-saving behavior. The standard is compliant with the UPnP Device Architecture v1.0 and enables UPnP devices to expose sleep and wake capabilities, notify network peers of low-power states, and be discovered or proxied while asleep.

Keywords: ISO/IEC 29341-16-11:2011, UPnP Low Power Service, UPnP Device Architecture, low power, BPMPX, wakeup, M-Search, SSDP.

Key topics and technical requirements

• Service model and State Variables: Defines state variables such as PowerState, BatteryLow, PowerSupplyStatus, SleepPeriod, WakeupMethod, and ExternalPowerSupplySource that describe device power conditions.
• Sleep state taxonomy: Specifies sleep types including Transparent Sleep, Deep Sleep Online, Deep Sleep Offline, Active, and Disconnect, and maps these to UPnP/IP bearer behaviors and wake mechanisms.
• Actions and control interface: Standardizes UPnP actions such as GetPowerManagementInfo(), Wakeup(), and GoToSleep() for control points to query or change power state.
• Discoverability and SSDP extensions: Describes how sleeping devices may or may not respond to SSDP M-Search and introduces optional SSDP extensions and headers for advertising low-power states.
• Basic Power Management Proxy (BPMPX): Specifies an optional network proxy (BPMPX) that caches low-power state information and enables locating or waking devices that don’t respond to M-Search while asleep.
• Eventing and moderation: Defines event notification behavior for low-power state changes and recommended moderation to limit network traffic.
• Compliance language: Uses RFC 2119 terms (MUST/SHOULD/MAY) to indicate mandatory and optional behaviors.

Practical applications and who uses it

• Device manufacturers and firmware engineers implement the Low Power Service to add standardized power-saving features to networked devices (e.g., printers, media servers, IoT sensors, smart home peripherals).
• UPnP control point developers and home-automation platforms use defined actions and state variables to discover, query, and wake sleeping devices.
• Network architects and system integrators use BPMPX concepts for maintaining visibility of low-power devices and coordinating wake mechanisms across Ethernet, Wi‑Fi, Bluetooth or other bearers.
• Useful in energy-efficiency initiatives, IoT deployments, smart buildings and any environment requiring coordinated power management across UPnP-enabled devices.
