RIL Application Development (Windows Embedded CE 6.0)


Application developers can use RIL functions to enable various phone features. RIL functions expose functionality required to implement radio-based telephone calls and data connections. This section includes conceptual information of interest to developers implementing calling and data connection scenarios.

RIL Architecture

Describes the two key architectural components of RIL: the RIL proxy and the RIL driver.

Voice Mail Retrieval on Two-Line Devices

Shows how to change the behavior of devices when retrieving voicemail on two-line devices using the registry.

Radio Interface Layer Changes for Suspend and Resume

Shows the RIL changes required to support the suspend and resume feature.

Dropped Connection UI GPRS and 1xRTT

Describes the required notification from RIL when the radio loses the signal or service.

Configuring CDMA and GSM Radios Default Phone Features

Describes how to use the HKEY_CURRENT_USER\ControlPanel\Phone\Features registry key to configure GSM and CDMA specific UI and radio features.

Configuring Simultaneous Data Connections

Describes the configuration of the RIL proxy support the use of multiple simultaneous GPRS contexts over PPP. This enables the use of multiple APNs simultaneously.

Network Identity and Time Zone (NITZ) Support

Describes the radio functionality needed to support NITZ.


Describes the set of services that enable you to create wireless-connection oriented services on your device.

Radio Interface Layer

Describes the Radio Interface Layer (RIL) that handles the communication between the CellCore system software and the radio hardware
