SMPP (Short Message Peer-to-Peer) is an open, industry standard protocol designed to provide a flexible data communications interface for the transfer of short message data between External Short Message Entities (ESME), Routing Entities (RE) and Message Centres (MC). The SMPP protocol is a means by which applications can send SMS messages to mobile devices and receive SMS from mobile devices.
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. 22.214.171.124).
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.
