SMS and MMS Toolkit - SmsProtocolSmpp object

Overview

SMPP stands for Short Message Peer to Peer Protocol SMPP is used to send and receive messages from and to GSM, UMTS, iDEN, CDMA and TDMA cell phones. The protocol is a level-7 TCP/IP protocol, which allows fast deliver of SMS messages. Using the SMPP protocol instead of sending/receiving messages using a GSM modem has the following advantages:

  • The SMPP protocol is TCP/IP based, GSM hardware is not required;
  • Users can send SMS to a simple shortcode, this is not possible when sending to a GSM phone;
  • High throughput (up to 200 messages per second);
  • Alphanumeric sender address can be assigned.

The SmsProtocolSmpp object features the following:

  • Send and receive SMS messages through an SMPP compliant SMSC provider;
  • Send and receive alphanumeric text and binary SMS messages;
  • Send and receive WAP Push messages or WAP Bookmark messages;
  • Verify delivery (so called 'status reports');
  • Support for Unicode, to support foreign languages like Chinese, Turkisch, etc.;
  • Support for multi-part messages, to allow messages longer than 160 characters.

The SmsProtocolSmpp object is part of the ActiveXperts SMS and MMS Toolkit component. Overview of all SMS and MMS Toolkit objects:

  • SmsProtocolGsm - Send and receive SMS messages using a GSM modem or a modem-capable GSM phone.
  • SmsProtocolSmpp - Send and receive SMS messages via an SMPP provider.
  • SmsProtocolHttp - Send (bulk) SMS messages through an SMS/HTTP compliant SMS provider over the internet/VPN.
  • SmsProtocolDialup - Send SMS messages using a normal Hayes compatible modem (1200 bps or higher).
  • MmsProtocolMM1 - Send and receive MMS messages via a GPRS modem through WAP (wireless application protocol).
  • MmsProtocolMM4 - Send MMS messages via an SMTP server. The protocol is based on SMTP, messages are MIME encoded.
  • MmsProtocolMM7 - Send and receive MMS messages via SOAP/XML using HTTP as the transport protocol.
  • PagerProtocolSnpp - Send pager messages via an SNPP provider through the internet/VPN.
