Gwmo overview

GwMO Overview

  • Facilitates interaction between a management server and a management client in situations where direct and unaided interaction between the management server and the management client is not possible

    • Device does not have a publicly routable address

    • Device sitting behind a firewall

    • Device supports a management protocol other than OMA-DM

  • Enables a single OMA-DM message, issued by a DM Server, to be fanned out to multiple end devices, and an aggregated response to be sent back to the DM Server


Modes of operation

Modes of Operation

  • GW MO Enabler provides framework for OMA DM to manage devices indirectly

  • Compatible DM v1.3 and later versions

  • Three different supported modes

    • Transparent

    • Proxy

    • Adaptation


Transparent mode

Transparent Mode

  • Transparent Mode

    • The DM Gateway assists the DM Server in sending a DM Notification to the End Device(s) behind the DM Gateway

      • The DM Gateway forwards the DM Notification to the End Device(s)

    • The DM Gateway does not participate in the management session that gets established between the DM Server and the End Device(s), after the delivery of the DM Notification to the End Device(s)


Proxy mode

Proxy Mode

  • Proxy Mode

    • The DM Gateway manages End Device(s) behind the DM Gateway on behalf of the DM Server over DM protocol. Scenarios:

      • Management of End Device(s) behind Firewall

      • Management of End Device(s) which may not have capabilities to access Internet

    • Multiple DM sessions are established; One is between DM Server and DM Gateway; Other DM sessions are between DM Gateway and each End Device

    • Supports command fanout and response aggregation

    • Useful for M2M scenarios

GwMO


Adaptation mode

Adaptation Mode

  • Adaptation Mode

    • Similar to the Proxy Mode with the difference that the DM Gateway manages End Device(s) behind the DM Gateway on behalf of the DM Server over non-OMA-DM protocols (such as UPnP DM, TR069, etc.)

GwMO


Gwmo architecture transparent mode

GwMO Architecture: Transparent Mode

  • GwMO-1 interface: Allows a GwMO Server to invoke GwMO Operations on the End Device via the DM Gateway using the underlying DM-1 interface

  • GwMO-2 interface:Allows the End Device to send GwMO Alerts to the GwMO Server via the DM Gateway using the underlying DM-1 interface

  • GwMO-3 interface:Allows the GwMO component to send notifications to End Device

  • GwMO-4 interface:Allows the DM Client to register its End Device to the DM Gateway.

  • DM-1 interface:Defined in the OMA DM Enabler. It provides a formal interface over which Servers may send device management commands to Clients and Clients may return status and alerts to Servers


Gwmo architecture proxy mode

GwMO Architecture: Proxy Mode

  • GwMO-1 interface: Allows a GwMO Server to invoke GwMO Operations on the End Device via the DM Gateway using the underlying DM-1 interface

  • GwMO-2 interface:Allows the End Device to send GwMO Alerts to the GwMO Server via the DM Gateway using the underlying DM-1 interface

  • GwMO-3 interface:Allows the GwMO component to send notifications to End Device

  • GwMO-4 interface:Allows the DM Client to register its End Device to the DM Gateway.

  • DM-1 interface:Defined in the OMA DM Enabler. It provides a formal interface over which Servers may send device management commands to Clients and Clients may return status and alerts to Servers


Gwmo architecture adaptation mode

GwMO Architecture: Adaptation Mode

  • GwMO-1 interface: Allows a GwMO Server to invoke GwMO Operations on the End Device via the DM Gateway using the underlying DM-1 interface

  • GwMO-2 interface:Allows the End Device to send GwMO Alerts to the GwMO Server via the DM Gateway using the underlying DM-1 interface

  • DM-1 interface:Defined in the OMA DM Enabler. It provides a formal interface over which Servers may send device management commands to Clients and Clients may return status and alerts to Servers

  • NDM-1 interface:Provides an interface over which Servers may send device management commands to Clients and Clients may return status and alerts to Servers using non-OMA DM protocol. This interface is outside the scope of OMA DM.


Sharing dm account by group of devices

Sharing DM Account by Group of Devices

  • Possible Additional Functionality (to be finalized):

  • DM Account can be assigned to each device

  • DM Account can also be shared for management of group of devices


Gwmo management objects

GwMO: Management Objects

Additional MOs may be identified as work on the GwMO Enabler proceeds.

  • Device Inventory MO

    • Maintains a list of Devices in the network that are managed through the DM Gateway

      • Device ID

      • Dev Info

      • Address

      • Mode

    • MO is populated as and when the DM Gateway becomes aware of new Devices in the network

  • Gateway Config MO

    • Maintains information regarding the handling of different types of Devices by the Gateway

      • Bootstrapping information

      • Device grouping based on various criteria. The group can be addressed for notification or command fanouts

      • Controlling the issuance of the Inventory Alert notification


Gwmo management objects1

GwMO: Management Objects

Additional MOs may be identified as work on the GwMO Enabler proceeds.

  • Fanout MO

    • Maintains information regarding the handling of DM Commands fanout and response aggregation

    • Issue the DM Commands to a single targeted End Device (specified by the Device ID in Device Inventory MO) OR issue the DM Commands to a group ID (specified in the Gateway Config MO)

    • Supported for Proxy Mode (and not Transparent Mode)

  • Image Inventory MO

    • Allows caching of data in the DM Gateway to optimize delivery of data to End Device(s)


Gwmo management objects2

GwMO: Management Objects

Additional MOs may be identified as work on the GwMO Enabler proceeds.

  • Alerts to DM Server

    • Device Inventory Update Alert

      • Issued by DM Gateway to DM Server to notify when there are Devices attached or detached

    • Device Attach Alert

      • Issued by the DM Gateway to DM Server when the DM Gateway detects a new device

    • Device Detach Alert

      • Issued by the DM Gateway to the DM Server when the device is detached from the DM Gateway


Work status

Work Status

  • RD and AD in Candidate status

  • Very good progress achieved on the TS

  • GwMO TS to reach Candidate status during 2011
