Overview

ISO/IEC 29341-27-1:2017 (part of the ISO/IEC 29341 UPnP Device Architecture series) defines the Friendly information update service of the Friendly Device Control Protocol. Aligned with UPnP Device Architecture 1.0, this standard specifies a service that lets UPnP control points perform orderly, moderated updates to a device’s Device Description Document (DDD) - specifically the device’s human-readable identity fields (for example, the device and ). It addresses the need to indicate pending versus advertised values while a device remains online and may be performing ongoing activities.

Key topics and technical requirements

• Service model and XML description: normative service type and XML service description for the FriendlyInfoUpdate service consistent with UPnP DCP conventions.
• State variables: definitions such as FriendlyNameStatus and FriendlyIconListStatus plus argument data types (e.g., A_ARG_TYPE_NewName, A_ARG_TYPE_IconURI, A_ARG_TYPE_Token).
• Actions: standardized operations for control points, including GetFriendlyName(), GetFriendlyIconList(), SetFriendlyName(), SetFriendlyIconList(), and RestoreFriendlyInfo().
• Eventing and moderation: event notifications and moderation rules to ensure consistent update sequencing and visibility of pending changes in the DDD.
• Security/Access control: support for DeviceProtection (UPnP DP) semantics - the standard identifies restrictable vs non-restrictable actions and allows restricting updates to control points with specific Roles.
• Error handling and state transitions: defined error codes and allowed icon/status transitions to ensure predictable device behavior during updates, reboots or network loss.
• Patent disclosures: the document records patent declarations by multiple technology companies; implementers should review intellectual property statements.

Practical applications

• Ensures consistent, race-free updates of device identity information in networked environments where devices cannot leave the network while changing attributes.
• Useful for smart home hubs, media devices, IoT endpoints, printers, gateways and any UPnP-enabled consumer electronics that advertise human-readable names or icons.
• Enables UX scenarios where remote management tools or provisioning systems update device names/icons while preserving advertised state consistency.

Who should use this standard

• UPnP device manufacturers and firmware developers implementing device description management.
• UPnP stack authors and middleware vendors adding FriendlyInfoUpdate support.
• Systems integrators and OEMs building provisioning or device-management platforms.
• Test labs and certification bodies validating UPnP DDD update behavior and DeviceProtection role-based restrictions.
