Overview

The Inetlab SMPP library implements SMPP protocol for two-way SMS messaging over TCP/IP. It allows to communicate with the SMSC (Short Message Service Center) or SMS provider. Using the library, you can send SMS messages to customers, receive messages from mobile devices and process delivery receipts. It supports long text messages in any encoding.

This is a robust SMPP framework for building production-grade solutions. Inetlab SMPP is helpful in such tasks as:

The Inetlab SMPP library is fully compliant with SMPP specifications v3.3, v3.4, v5.0 and comes with a comprehensive set of code samples.

Features

SMPP Client

SMPP client integrates SMS functionality into your application. It serves for connecting to an SMSC over TCP/IP, sending and receiving short messages from the SMSC. The class implements events fired on receiving messages from mobile network. It also provides tools for programming interactions with any USSD center.

SMPP Client Features

Features

  • Sending long Text messages as concatenated segments
  • Sending Binary messages

SMPP Server

SmppServer class is a main building block for anyone willing to provide SMPP services for customers. It allows developers to start SMPP server and accept plenty of concurrent connections from clients. Processing concatenated messages, tracking delivery reports and interacting with third-party load-balancers is fairly straightforward with the library. SmppServer is based on async- multi-thread architecture (Task-based asynchronous pattern) and provides an extremely high stability level.

SMPP Server Features

Features

  • Multiple concurrent client connections support
  • Receiving SMS messages from connected clients
  • Sending Concatenated Text messages
  • Sending Delivery receipts
  • Message status query support
  • Message rate limit and throttling
  • Ability to forward received messages to next SMPP server
  • SSL/TLS support
  • Tests availability of client with enquiry_link command
  • Proxy Protocol for load-balancing support

Message Types & Encodings

Message Types & Encodings

The Inetlab SMPP .NET component supports all necessary character sets including GSM 03.38 and Unicode. It operates in any language including Arabic, Chinese, Hebrew, Russian and Greek.

The following message types are supported:

  • Short text SMS
  • Long text messages as concatenated SMS parts
  • Binary messages
  • USSD operations
  • Flash SMS
  • WAP Push
PDU creation and manipulation

PDU creation and manipulation

SMS messages are transferred over a network as Protocol Data Units (PDUs). The Inetlab SMPP library implements all types of SMPP commands and responses. It includes SMS builder fluent-interface for simple and intuitive PDU creation without worrying about message text length. There is also a special MessageComposer class helping to get full message text from a sequence of concatenated parts.

Logging

Logging

Logging features are very important for any developer to test and debug the software at development and production stage. The Inetlab SMPP component includes logging interfaces for peeking inside each operation performed. Well-formed log saves your time!
