RIL_NOTIFY_REGSTATUSCHANGED

Network registration status has changed. The lpData notification parameter points to the new status (line registration constant).

RIL_NOTIFY_CALLMETER

Call meter has changed. The lpDatanotification parameter points to a DWORDcontaining new current call meter value.

RIL_NOTIFY_CALLMETERMAXREACHED

Call meter maximum has been reached. The lpDatanotification parameter is NULL.

RIL_NOTIFY_GPRSREGSTATUSCHANGED

Network registration status has changed. The lpDatanotification parameter points to the new status (line registration constant).

RIL_NOTIFY_SYSTEMCHANGED

Indicates that the type of coverage which is available has changed. The lpDatanotification parameter points to the system type constants defined in System Type Constants.

Use this notification when implementing a RIL driver for CDMA devices. Send this notification with the lpDataparameter pointing to RIL_SYSTEMTYPE_NONEwhen the device is not registered on the network. This will remove any system type icon from the display.

When the device is registered on the network, send the notification with the lpDataparameter pointing to the correct system type, and the system type icon will appear on the display. For example, if the lpDataparameter points to RIL_SYSTEMTYPE_1XRTTPACKET, the 1xRTT icon appears on the display.

RIL_NOTIFY_GPRSCONNECTIONSTATUS

Indicates that the PDP context state has changed. The lpDatanotification parameter points to RILGPRSCONTEXTACTIVATED.

RIL_NOTIFY_SYSTEMCAPSCHANGED

System capability has changed. The lpDatanotification parameter points to one of the new system capability constants defined in System Capabilities Constants.

Use this notification when implementing simultaneous voice and data support in the RIL driver. Send this notification with the lpDataparameter pointing to RIL_SYSTEMCAPS_VOICEDATAwhen simultaneous voice and data is supported by the RIL driver.

RIL_NOTIFY_LOCATIONUPDATE

Location data associated with the device has changed. The lpDatanotification parameter points to a RILLOCATIONINFOstructure.

This notification is intended for use with Push to Talk functionality, and is not currently implemented in any Microsoft application. If no OEM RIL applications are set to handle this notification, then the radio does not need to notify its host of any LAC/CellID changes.
