+ * Represents the GNSS location reporting permissions and notification interface.

+ * non-framework (NFW), non-user initiated emergency use cases, and to notify the framework user
+ * of these GNSS location information deliveries.
+ *
+ * For user initiated emergency cases (and for the configured extended emergency session duration),
+ * the GNSS HAL implementation must serve the emergency location supporting network initiated
+ * location requests immediately irrespective of this permission settings.
+ *
+ * There is no separate need for the GNSS HAL implementation to monitor the global device location
+ * on/off setting. Permission to use GNSS for non-framework use cases is expressly controlled
+ * by the method enableNfwLocationAccess(). The framework monitors the location permission settings
+ * of the configured proxy applications(s), and device location settings, and calls the method
+ * enableNfwLocationAccess() whenever the user control proxy applications have, or do not have,
+ * location permission. The proxy applications are used to provide user visibility and control of
+ * location access by the non-framework on/off device entities they are representing.
+ *
+ * For device user visibility, the GNSS HAL implementation must call the method
+ * IGnssVisibilityControlCallback.nfwNotifyCb() whenever location request is rejected or
+ * location information is provided to non-framework entities (on or off device). This includes
+ * the network initiated location requests for user-initiated emergency use cases as well.

+ * The HAL implementations that support this interface must not report GNSS location, measurement,

+ * expressly authorized by this HAL. This includes all endpoints for location information
+ * off the device, including carriers, vendors, OEM and others directly or indirectly.
