Abstract
Example embodiments presented herein are directed towards a Policy and Charging Rules Function (PCRF) node, a network node and a wireless device, as well as corresponding methods therein, for monitoring an ability of a wireless device to receive downlink data. The example embodiments presented herein provide a means of notifying an application server of when a wireless device is reachable. Thus, by knowing when the wireless device is reachable, the application server may avoid sending communication request to the wireless device when the device is unavailable. Thus, unnecessary signaling may be avoided.
