| SMPP ProtocolConnectionThrough our SMS gateway, it is possible to send messages using the SMPP protocol versions 3.4 and 5.0.
To get access via the SMPP protocol, you must enable it in the settings in the group "API Settingsselect the
appropriate option and add the IP addresses from which you will connect on this page.
SMPP server address: smpp.smscentre.com, port: 3700.
For an encrypted SSL connection, port 3443 is used.
Address of the backup SMPP server: smpp2.smscentre.com.
Example of connection settings (kannel format):
group = smsc
smsc = smpp
smsc-id = smsc
host = smpp.smscentre.com
port = 3700
smsc-username = <login>
smsc-password = <password>
system-type = ""
interface-version = 34
source-addr-autodetect = yes
source-addr-ton = 5
source-addr-npi = 1
dest-addr-ton = 1
dest-addr-npi = 1
validityperiod = 1440
transceiver-mode = true
receive-port = 0
enquire-link-interval = 60
wait-ack-expire = 0
max-pending-submits = 300
throughput = 30
The maximum possible inactivity interval is 2 minutes. During this time, the Client needs to send a message or execute an empty ENQUIRE_LINK command, otherwise the connection will be terminated due to inactivity..
Example of additional settings for SSL connection (kannel versions 1.4.4 and higher):
...
port = 3443
ssl-client-certkey-file = "/etc/kannel.pem"
use-ssl = 1
...
The certificate can be generated by the command (Linux CentOS): /etc/ssl/certs/make-dummy-cert kannel.pem
The login is used from the personal account, the password must be created on the pagePasswords for access. The username and password must not be in Russian.
This section contains only a brief description of the SMPP protocol. For more information, see the specification.
Download the SMPP Protocol Specification v3.4 smpp34.zip (500 Kb)
smpp34rus.zip (1,1 Mb).The speed of mailing listsThe connection bandwidth or the number of SMS messages sent every second depends on the size of the transmission window (smpp window size).
In the example settings, this parameter is called max-pending-submits. For mass mailings, it is better to set large values (1000-2000).
Also in the example, the throughput parameter sets a limit on the maximum number of SMS messages per second..
Along with mass mailings, you can also send urgent single SMS notifications via a single connection. The system will set the maximum priority
for such messages and send them before any mass mailings without waiting in the queue.
When sending mass messages, do not forget about the system for monitoring the speed of sending messages per second, when exceeding which an error of exceeding the speed is generated (throttling). If this error is received, the SMPP-standard Client must repeat the sending, reducing the overall speed on its side. By default, the speed is set to 30 SMS / sec for each account. To change the maximum allowed speed, you need to send a request to the service support service.Multiple connectionsBy default, the server processes only one connection from one login at a time for a more correct return of statuses,
so when you reconnect, the previously connected connection with the same username will automatically terminate.
If you need to have multiple simultaneous connections to increase the speed of sending, you can
set the following parameter in the settings of all connections (multi connection):
system-type = "MCON2"
or
system-type = "MCON9"
The value after MCON can be from 1 to 9 and specifies the number of simultaneous connections.
Simultaneous connections with different usernames linked to the same personal account and account are also possible.
To do this, you need to create additional accounts with the required subaccount type in your personal account in the "Reseller" section.Sending a messageSending an SMS message
To send an SMS message, use the SUBMIT_SM command according to the specification.
The following encodings are supported:
- 7-bit GSM for Latin text with support for European characters − (coding = 0);
- 8-bit ISO-8859-1 (ASCII) for Latin text or binary data − (coding = 1);
- UCS2 (UCS-2BE or UTF-16BE) for national alphabets (for example, Russian) − (coding = 2).
The coding field is encoded by two bits in the composite data_coding field, so data_coding = coding * 4.
To use the ISO-8859-1 (ASCII) encoding instead of GSM when connecting, you need to specify:
system-type = "ISO"
You can add comments to the text of the SMS message , which are intended for
the sender to view the message history in the personal account.
The SUBMIT_MULTI command for multiple mailing is not yet implemented.
The server does not accept more than one identical request to send SMS messages within a minute to protect against errors and loops in the Client-side program in order to reduce the load and not waste the Client's funds, as well as to prevent multiple messages from being sent to one subscriber.
The server also blocks sending more than 50 messages to one subscriber, which were sent with a break
between messages of less than 30 seconds, to protect against flooding and unnecessary debiting of funds from the Client's account,
since many operators do not pass a large number of messages to one subscriber in a short period of time.
When sending a composite message, all SMS parts must be transmitted to the server within a minute. Otherwise
, the operator may reject the message, since to check for filters and templates, all SMS parts must first be
glued together, and most operators wait no more than a minute.
Comments in SMS messages
When sending SMS messages, you can add any comment to the end of the text that clarifies or supplements the SMS message for the sender.
This text will not be sent to subscribers and will not affect the cost of SMS and is available for viewing and filtering in the list of sent messages in your personal account.
To add a comment, you must specify a special combination "\n~~~\n " at the end of the text of the SMS message intended for sending
(line feed, 3 of the tilde character, and again line feed), and after that, any text that will be considered a comment will not be sent to the subscriber,
but will be displayed in the history.Sending an e-mail message
To send an e-mail message, use the SUBMIT_SM command with the text " _ _ MAIL__: <message><message>\nsubj:<subject>" (text "_ _ MAIL__", colon, space, message text, line feed, word "subj", colon, subject of the e-mail message).Sending a voice message (call)
To send a voice message, use the SUBMIT_SM command with the text " __CALL__: <message><message>\nvoice:<voice><voice>" (text "__CALL__", colon, space, message text, line feed, word "voice", colon, voice used to voice the text).
Possible values for the voice used:
- m – male voice.
- m2 – male voice 2.
- m3 (default) – male voice 3.
- m4 – male voice 4.
- w – a woman's voice.
- w2 – female voice 2.
- w3 – female voice 3.
- w4 – female voice 4.
When sending messages, it is also possible to specify the language of the text in the form: "m,en", "w,fr", "w,de", etc..
In the process of forming a message, at the end of the text, you can specify a special combination "\n~~~\n" (line feed, 3
tilde character and line feed again), after which you pass the param parameter, which determines some characteristics of the call
(more details can be found in the description).Sending a viber message
To send a viber message, use the SUBMIT_SM command with the text "__VIBER__: <message>" (text "__VIBER__", colon, space, message text).
When forming the message text, you can use special macros to create a button that will open the browser and click on the link specified in the macro, as well as attach files. More details
additional features for sending viber messages are described in the documentation for the http protocol.Sending a soc messageTo send a soc message sent to users of the Odnoklassniki, VKontakte, or Mail.Ru Agent social networks, use the SUBMIT_SM command with the text "__SOC__: <message>" (text " _ _ SOC__", colon, space, message text).
Sending a message to TelegramTo send the confirmation code to Telegram, use the SUBMIT_SM command with the text "__TGM__: <code>" (text "__TGM__", colon, space, confirmation code).
Only numeric codes with a length from 4 to 8 digits are accepted for sending.Sending a message to the Telegram chatbot
To send a message to the Telegram chatbot, use the SUBMIT_SM command with the text "__BOT__: <message>\nbot:@<bot_name>" (text "__BOT__", colon, space, message text, line feed, text "bot", colon, bot name).Sending an HLR request
To send an HLR request, use the SUBMIT_SM command with the text __HLR__.
The result of the request comes in the usual status (Delivery Report), which can be received
both via the SMPP connection and via HTTP to your handler.
Status format with the result of an HLR request returned by SMPP:
id:<id> stat:<status> err:<err> imsi:<imsi> msc:<msc> mcc:<mcc> mnc:<mnc> cn:<cn> net:<net> rcn:<rcn> rnet:<rnet>
Description of parameters:
| Option | The value
|
|---|
| id | Message ID.
|
|---|
| status | Message status.
|
|---|
| err | Error code if the subscriber is unavailable (list).
|
|---|
| imsi | Unique IMSI code of the subscriber's SIM card.
|
|---|
| msc | The number of the service center of the operator in whose network the subscriber is located.
|
|---|
| mcc | Numeric code of the subscriber's country.
|
|---|
| mnc | Numeric code of the subscriber's operator.
|
|---|
| cn | Name of the country of registration of the subscriber.
|
|---|
| net | Name of the subscriber registration operator.
|
|---|
| rcn | The name of the roaming country of the subscriber when he is in a foreign network.
|
|---|
| rnet | The name of the roaming operator of the subscriber when he is in someone else's network.
|
|---|
String data, such as country and operator, is encoded via the urlencode function.
Example of the result of an HLR request:
id:855469 stat:DELIVRD err:000 imsi:250023012345678 msc:79232510066 mcc:250 mnc:02 cn:Russian+Federation net:MegaFON+open+Joint+Stock+Company rcn: rnet:
Sample PHP code for parsing a string with the result of an HLR request:
$dlr = strtr($dlr, ": ", "=&"); // $dlr - ñòðîêà ñòàòóñà
parse_str($dlr, $m); // $m - ìàññèâ ïàðàìåòðîâ, $m["id"], $m["err"], $m["imsi"] è òä.
Example of parsing through regular expressions:
preg_match("/^id:(\d+) stat:(\w+) err:(\d+) imsi:(\d*) msc:(\d*) mcc:(\d*) mnc:(\d*) cn:([^ ]*) net:([^ ]*) rcn:([^ ]*) rnet:([^ ]*)/", $dlr, $m); // $dlr - ñòðîêà ñòàòóñà
for ($i = 6; $i <= 9; $i++)
$m[$i] = urldecode($m[$i]);
// $m - ìàññèâ ïàðàìåòðîâ, $m[1] = id, $m[2] = status, $m[3] = err è òä.
To send a Ping-SMS, use the SUBMIT_SM command with the text _ _ PING__.Checking the status
You can get the delivery status of a sent SMS message via the SMPP protocol either automatically
by receiving the DELIVER_SM response PDU command from the server immediately after the status change, or
by using a separate QUERY_SM command on request. To automatically get the status via the SMPP protocol, you need to connect in the following mode:
transceiver or receiver and when sending SMS, specify the status request flag (registered_delivery).
If you do not specify this flag when sending, the message statuses will be passed to the HTTP handler.
When the status is automatically returned, the DELIVER_SM command passes the standard TLV parameters recipted_message_id (<id>), message_state (numeric <status>) and network_error_code (<err>), as well as additional TLV fields described below:
| Field name (code) | Size | Type | Description
|
|---|
| 8192 (0x2000) | Var. max 6 | COctet String | The cost of the message in the format " n.nnnn".
|
|---|
| 8193 (0x2001) | 2 | Integer | A flag in the form of a 2-byte number containing various information about the message. Combinations of bit values of different characteristics are possible.
0-3 bits (message type):
0 (by default) – SMS.
1 – Flash-SMS.
2 – Binary SMS.
3 – Wap-push.
4 – HLR-query.
5 – Ping-SMS.
6 – MMS.
7 – Call.
8 – E-mail.
10 – Viber.
12 – Social network.
Bit 5 – payment of the message from the second balance.
Bit 8 - indicates a template message.
Bits 10,9 are the type of template message:
00 - service.
01 - transactional.
10 - authorization.
11 - advertising.
|
|---|
| 8194 (0x2002) | 2 | Integer | Number of parts per message.
|
|---|
| 8195 (0x2003) | Var. max 5 | COctet String | mccmnc Subscriber's country/operator code.
|
|---|
| 8196 (0x2004) | 2 | Integer | Additional message status (2 – read, 4 – link clicked).
|
|---|
The DELIVER_SM command also passes the status text in the following format:
id:<id> sub:<sub> dlvrd:<dlvrd> submit date:<submit date> done date:<done date> stat:<status> err:<err>
Description of parameters:
| Option | The value
|
|---|
| id | The message ID assigned by the server when sending the message.
|
|---|
| sub | The number of SMS parts in the sent message.
|
|---|
| dlvrd | Number of SMS delivered.
|
|---|

Example of the result of the status bar (Delivery Report):
id:854019 sub:001 dlvrd:001 submit date:1108202241 done date:1108202241 stat:DELIVRD err:000
By default, for long messages that are split into multiple SMS messages, the server returns only one status (DELIVER_SM)
for the entire glued message and the same ID in the SUBMIT_SM_RESP response for all SMS parts of this message.
To enable the processing mode and return statuses for each SMS part, set the following parameter separately in the connection settings (or in the settings of your personal account):
system-type = "SINGLE"
If you need to specify several parameters in the system-type field, then specify them separated by commas:
system-type = "ISO,SINGLE"
Receiving incoming messages
To enable the forwarding of incoming SMS messages via SMPP connection, you need to check the box "Send incoming SMS via SMPP connection" in the settings of your personal account (the drop-down tab "API Settings") or contact the support service. In this case, the transmission of incoming messages to the Client handler must be disabled.
Incoming messages are received in the DELIVER_SM PDU command. To receive it, you need to connect to the SMPP server in the transceiver or receiver mode.Error codes in the statusPossible error codes in the status of messages or HLR requests (values of <err>):
