SMS Tutorial 06 -- The Fundamentals of SMPP Protocol
ฝัง
- เผยแพร่เมื่อ 5 ส.ค. 2024
- When you develop your SMS application, it is better to know the theories behind the SMPP protocol. You will definitely need the Specification of SMPP Protocol. It could be hard and sometimes even frustrating for some beginners to grab the technical documentation and fully understand it. The problem could be you might not even know what question to ask and how to ask. This lesson sets you up so that you will be able to utilize the SMPP Protocol Specification and you will be able to raise questions when you want to know certain details.

+chocobros77 Thank you for the encouragement!
I m frm SAP DIGITAL INTERCONNECT TEAM ONE OF THE GIANT & TOP SMS COMPANY UR VIDEOS R GREAT
thanks a lot!!
Good session
Tooooooooooooop
Thank you very much, it is really helpful. Is there any chance to post a video describing how ESME can have confirmation receipt that the SMS is reached to the destination
Hi! Thank you for your support. As a quick solution, can you try the following steps?
1. Make sure SMSC is configured to be able to generate and deliver the delivery receipt. In SMPPSim, you might modify the following parameters, via "conf/smppsim.props": 1) DELAY_DELIVERY_RECEIPTS_BY 2) PERCENTAGE_THAT_TRANSITION 3) DELIVERY_RECEIPT_OPTIONAL_PARAMS 4) DELIVERY_RECEIPT_TLV 2. Make sure the client (ESME) binds to SMSC as transceiver 3. Before submitting submit_sm PDU, setRegisteredDelivery((byte) 1) 4. After submitting submit_sm PDU, try DeliverSM deliveryReceipt = (DeliverySM) smppSession.receive(); 5. If deliveryReceipt abovementioned has esm_class == 4, then that's the delivery receipt 6. You can try deliveryReceipt.getMessageState(), deliveryReceipt.getNetworkErrorCode(), deliveryReceipt.getReceiptedMessageId()
Hope it helps
Thank you so much!!! l have some issue when implementing smpp! l can get message from sender when my pdu instanceof EnquireLink. Please help
Hi! Do you mean you cannot receive the EnquireLink pdu?
Could you please tell me the difference btw data_sm and submit_sm in smpp?
Hi! Here are some excerpts from SMPP 5 documentation. Hope it answers your question.
Message submission operations provide an ESME with the ability to submit messages for onward delivery to mobile stations. This operation is used by an ESME to submit a short message to the MC for onward transmission to a specified short message entity (SME).
The data_sm operation is similar to the submit_sm in that it provides a means to submit a mobile-terminated message. However, data_sm is intended for packet-based applications such as WAP in that it features a reduced PDU body containing fields relevant to WAP or packet-based applications.
I am totally new to SMPP, why would you need to send enquire_link to keep a session open? In other words, why keep a bind session open? Is it to send multiple messages over the same bind connection, or is it purely because the ESME is awaiting a response from the SMSC?
Hi! Thanks for your question. Here is a description from the SMPP Documentation: This PDU (referring to enquire_link PDU) can be originated by either the ESME or MC and is used to provide a confidence-check of the communication path between an ESME and a MC. On receipt of this request the receiving party should respond with an enquire_link_resp, thus verifying that the application level connection between the MC and the ESME is functioning. The ESME may also respond by sending any valid SMPP primitive.
First of all let's be aware that when we send SMS via SMSC, we need to connect the ESME to the SMSC and "login" to SMSC. In the SMPP world, what you say "keeping a session open" is like keeping the login session active. If the login session is inactive, then obviously you won't be able use the service. If the login session is idle for too long (meaning that you logged in and do nothing at all for too long), then the system will automatically sign you out. The same applies to SMSC.
The main purpose of enquire_link PDU and enquire_link_resp PDU being sent back and forth between ESME and SMSC periodically, is to keep the session open / awake / active, so that your ESME can submit the messages to the SMSC without binding again. Of course you can (reinvent the wheel and) send other types of PDU to keep the session open. But make sure both SMSC and ESME can "understand" that PDU and process it appropriately. Let's say, if you send other type of PDU such as submit_sm frequently, then the SMSC will keep the session open, but it will treat submit_sm as a regular SMS and send it out frequently, which is not good. This is pretty much why enquire_link is used.
Hope it helps.
ALB Programming excellent explanation, thank you!
You're welcome. Thank you
how can i transform the code of transmitter ,receiver,transcever with spring boot?
Hi! You need to add the jar to your build path. Then copy the code where necessary
How can we send a wap push sms using the smpp protocol using java?
Hi! First of all, please know that I have never worked with WAP so far. What I am familiar with only is the interaction between ESME and Message Center. But if I were in your situation I would try the following.
1. Find out resources and documentations on WAP implementation. This is what I came across: smpp.org/SMPP_WAP_Implementation_Guide.pdf
2. Ask your colleagues if they have a working sample, from which you can start.
3. Make sure your message center allows you to send WAP push
4. Bind to your message as TRANCEIVER to the message center
5. Consider using data_sm operation. For example, in opensmpp.jar there is a class, named DataSM. In addition, I would keep an eye on esm_class parameter.
I guess you also need to take care of the interaction between the web server and WAP Proxy Server, which shouldn't have too much to do with SMPP.
Hope it helps.
