Communications: Internet: OTA (Network)
Functional Description

OTA Network allows the network provider to send a set of network configuration to a mobile device with no user interaction required to create a working Internet connection. Qt Extended processes the network configuration messages and writes the received settings to a file. Two distinct formats of OTA network configuration messages are supported:

  1. Nokia's Over the Air Settings Specification 7.0
  2. WAP/OMA standards (wap-183-provcont-20010724-a.pdf and OMA-WAP-ProvCont-v1_1-20050428-C.pdf).

New Configuration options are automatically matched against existing configurations and if no existing configuration is available, new Internet/WAP accounts are created. The entire process does not require any interaction with the user, however for security reasons the user can refuse to accept configuration changes. Once the changes are applied, new options are integrated into the Qt Extended network configuration and can be used by starting the appropriate accounts.

Features

Network configuration

Qt Extended can process OTA network configuration messages and writes the received settings to a configuration file.

The Internet application is responsible the processing of received OTA messages. Depending on the message content it
may change Internet, WAP and MMS accounts.

Qt Extended supports two distinct formats of OTA network configuration messages:

The following configuration options are used by Qt Extended and its applications:

New options are automatically matched against existing configurations. If there is no existing configuration available, new Internet/WAP accounts are created. The entire process does not require any interaction with the user. However for security reasons the user can refuse to accept configuration changes. Once the changes are applied new options are integrated into Qt Extended's network configuration and can be used by starting the appropriate accounts.

OTA Update

Other forms of OTA Update are typically handled by SMS push services, dispatching on either MIME type or port number. The infrastructure for this is present in the telephony library. Applications in specific functional areas handle the messages in question, dispatched via QDS service messages.

SIM Download

GSM 11.14 specifies a method to download data directly to the SIM, used by operators to modify the user's settings. From section 7.1.1 of GSM 11.14:

If the service "data download via SMS Point-to-point" is allocated and activated in the SIM Service Table (see TS 11.11 [20]), then the ME shall follow the procedure below:

Many modems already do this internally, without notifying Qt Extended, so there is nothing to be done to support this on those modems. For modems that don't support SIM download internally, Qt Extended passes the download message to the vendor-specific plugin to be handled according to the modem's specific requirements.
