The CPE WAN Management Protocol: TR-069
DSLHome (from DSLForum) defined the CPE WAN management protocol (TR-069) for
 Auto-configuration and dynamic service provisioning
 Software/firmware image management
 Status and performance monitoring
 Log file, and dynamic notification
 Diagnostics
TR-069 features
 TR-069 has notion of sessions over TCP/IP (integrity, authentication, security)
 Simple TR-069 object model and profiles (all standardized!!!)
 TR-069 is an event-driven model
 TR-069 has dynamic active and passive notification
 TR-069 CPE WAN remote management protocol is access agnostic
 TR-069 allows End-users devices (RG, STB, VoIP,…) management (TR-111)
 TR-069 is designed to handle millions of devices (scalability, robustness)
Interoperability guaranteed through standardized objects models and plug fest
Huge Market traction and adoption (by SP, chipset vendors, CPEs vendors)

TR-069 topics (1/2)
Protocol
 HTTPS/SOAP
 CPE initiated connections
 Periodic
 Triggered by parameter change (‘Active Notification’)
 ACS initiated connections
 Connection request
 NAT support: TR-111
RPC methods:
 General methods:GetRPCMethods
 CPE methods: Get-/Set- ParameterValues, Get-/Set ParameterAttributes, …
 ACS methods: RequestDownload

TR-069 topics (2/2)
Data model:
 Standardized models, with possible vendor extensions
 Structured in tree
 Each parameter is a name-value pair
 E.g. Device.Device.DeviceInfo.Description
 E.g. Device.Services.OSGi.FrameworkInfo.version
 Each parameter has attributes
 E.g. Notification, Access List

TR-069: OSGi remote management
Define mechanisms to enable TR-069 remote management for:
 Platform management
 Bundle life-cycle management
 Bundle configuration management
 Eventing and logging
 Mapping of discovered devices to TR-069: e.g. UPnP devices

OSGi TR-069 management checklist (1/2)
Platform and bundle management
Discovery
 Discovery of platform
 Discovery of bundles
 Discovery of services
Bundle life cycle management
 Start/stop/uninstall
 Download
(via TR-069 extension)
 Startlevel
 Permissions

OSGi TR-069 management checklist (2/2)
Bundle configuration and control
 Configuration admin interface
(some limitations identified)
 Bundle run-time configuration/actions
 Needs TR-069 compatible interface
 Mobile approach (DMTAdmin/DMT Tree) does not map to TR-069 requirements
Events and logging
 Events
(via Event Admin service + notification)
 Logging
(via Log Service + TR-069 upload)
External device discovery
 UPnP

TR-069 management for OSGi: new requirement
Requirement:
TR-069 compatible bundle interface
Why:
- TR-069 based remote management of OSGi platform is natural extension of
current remote management of fixed devices (gateway, VoIP, STB, …)
- Current mobile spec (DMT Admin/DMT tree) does not map to TR-069 protocol
and data model
What:
standardize bundle interface, and procedures (e.g. registering interface in the
service registry) for TR-069 based remote management

Conclusion
 Most features necessary for basic TR-069 based remote management are
available
 The one missing feature is a bundle interface compatible with TR-069 based
management

High level overview of TR-069 object model
 OSGi information starts under Device.Services branch of data model
(conform to TR-106)
 Main OSGi related top level branches:
 .OSGi.FrameworkInfo
 .OSGi.FrameworkConfig
 .OSGi.Bundle.{i}
 .OSGi.Services.{i}
 Detected UPnP services also start from Device.Services
 .UPnP.Devices.{i}
