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 multimedia SMS messages, including ringtones, pictures and logo's;
- Send and receive WAP Push messages, WAP Bookmark messages, voicemail/e-mail/fax indications;
- 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.
