The RIL miniport driver component is an NDIS intermediate driver that creates the interface through which IP configuration information passes between the TCP/IP stack and the RIL.
The following illustration shows the path taken by packets between the radio hardware and the TCP/IP stack.

The RIL Miniport Driver exposes the 802.3 NDIS miniport interface. The 802.3 interface is exposed to TCP/IP and other protocol drivers. The miniport driver also exposes a set of wireless Wide Area Network (WWAN) configuration and notification NDIS object identifiers (OIDs).
The miniport driver uses RIL APIs to send and receive packets, to configure the 802.3 interface and to get status about the 802.3 interface.
The illustration above also shows the path from the Connection Manager to the RIL miniport driver. This path uses the NDISUIO (NDIS User-Mode I/O) packet driver interface. The Connection Manager uses the RIL miniport driver to help accomplish the following tasks.
- Establish GPRS connections
- Disconnect GPRS connections
- Monitor the status of GPRS connections
Note
WWAN-based GPRS is not supported on the P2Sample platform.
