4.1.3 Alert Notification Operation

The alert_notification PDU is sent by the MC to the ESME across a Receiver or Transceiver session. It is sent when the MC has detected that a particular mobile subscriber has become available and a delivery pending flag had been previously set for that subscriber by means of the set_dpf TLV (ref. 4.8.4.52).

A typical use of this operation is to trigger a data content "Push" to the subscriber from a WAP Proxy Server.

Note: There is no associated alert_notification_resp PDU.
