+ * of these GNSS location information deliveries.
+ *
+ * For user initiated emergency cases (and for the configured extended emergency session duration),

+ * 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.
