SMPP INTRODUCTION

Short Message Peer-to-Peer (SMPP) is using for sending and receiving SMS-traffic between different sides. SMPP is especially popular among active users of SMS, including aggregates and operators.

The SMPP server

HOST

5.178.83.10

Bindings and Throughput

Whenever an SMPP account has been setup for you, you’ll receive the maximum amount of binds you’re allowed to set up as well as a maximum throughput. In most cases, these values will be something like 3 binds and 50 messages per seconds. NOTE that BSG SMPP server supports only one connection via transceiver (TRX) or multiple connections via transmitter (TX) with one connection via receiver (RX) if needed.

Username and Password

Your username (system_id) and password (SMPP-password) will be given to you by your account manager at BSG or you can generate SMPP-password in your account settings.

Security

For SMPP connection BSG require whitelisting your originating IP. In order to access, please send your username and originating IP to our Customer Care team at: support@bsg.hk.

Bind PDU

An SMPP bind_receiver, bind_transceiver or bind_transmitter PDU request has a fixed set of fields. Most fields are irrelevant to us. In fact, we only read the system_id, password, system_type and interface_version fields and the rest is ignored.

Field name
Description
system_id

The username

password

SMPP-password

system_type

IGNORED if you want use default tariff or set tariff-x, where x is the code of tariff name

interface_version

The SMPP protocol version you want to talk

addr_ton

IGNORED

addr_npi

IGNORED

address_range

IGNORED

Interface_Version

The BSG SMPP server supports SMPP protocol version 3.4 and 5.0 NOTE for SMPP 5.0! In case the command SUBMIT_SM_RESP contains a status with an error code the length of PDU is 16 octets.

Data_Coding

The values for the data_coding field are not solidly declared in the SMPP spec, so each SMPP server is more or less required to give its own definition.

Value
Encoding
0

Default Alphabet (GSM 3.38), 7-bit characters

1

IA5/ASCII, 7-bit characters

3

ISO-8859-1 (LATIN1), 8-bit characters

5

Japanese (JIS), multi-byte characters

6

Cyrillic (ISO-8859-5), 8-bit characters

7

Latin/Hebrew (ISO-8859-8), 8-bit characters

8

Unicode (USC-2), 16-bit characters

14

Korean (KS C 5601), multi-byte characters

For 7-bit character sets, a maximum of 160 characters can fit into an SMS message; for 8-bit character sets, the limit is 140 characters; for 16-bit character sets, the limit is 70 characters; for multi-byte character sets, the limit is somewhere between 70 and 140 characters, depending on which characters make up the text of the message. (For multi-byte character sets, most characters are 16 bits; some of the more common characters are eight bits.)
