Pushing XML OTA by Using Service Indication (SI)

  • Article

4/8/2010

If the provisioning XML file is in a signed .cab or .cpf file, you can push the file to a device by using a Service Indication (SI) message. Service Indication is a WAP push feature. For more information, see SI and SL XML Files.

SI messages are sent in connectionless unsecure WAP push operations from the Push Proxy Gateway, which encodes them by using WAP Binary XML (WBXML) tokens.

Note

Security roles can impact the configuration result. For information on role-based access control, see OMA Client Provisioning Security Best Practices.

The following illustration shows a graphical view of how the provisioning XML is pulled to the device by using SI.

For a description of the user experience with SI, see SI and SL Notifications Behavior.

To deliver a provisioning XML file by using SI

  1. Put the .cab or .cpf file that contains the provisioning XML file on a Web site from which the user can download the file.

  2. Create the SI XML file to send a message to the user.

    SI and SL messages are simple XML files, so you can create them in any text editor. For proper syntax, see SI Message Format.

  3. Send the SI message to the user by using a WAP push over an SMS channel.

    The user is prompted with a dialog box that contains a hyperlink to the Web site that contains the provisioning file. The user can download the provisioning file by clicking on the link.
