Here we will talk about SMS solution providers or those applications which use SMS in their application. There are mainly 2 ways third party application can use SMS services:
A) Very Preemptive/simple:
Here application connects to the third party aggregator or SMS Gateway(s) and send/receive message. In general this flow can have flowing 2 varieties:
i) Only for Sending Messages:
Third party application sends the message as bulk to SMS Gateway or SMS Aggregator via HTTP/SMPP/CIMD. SMS Gateway/Aggregator will send the message to operator SMSC(s) via SMPP/CIMD/HTTP.SMSC then sends the message to the intended Subscriber.
ii) Both Sending and Receiving Messages:
Third party application sends the message as bulk to SMS Gateway or SMS Aggregator via HTTP/SMPP/CIMD. SMS Gateway/Aggregator will send the message to operator SMSC(s) via SMPP/CIMD/HTTP.SMSC then sends the message to the intended Subscriber.
Now, if the Subscriber wants/needs to reply back to the application with response (say, for Purchasing content/subscribing for Jokes etc.) s/he sends it and it reaches to the Operator SMSC and SMSC then finds the SMS Gateway/Aggregator to deliver the SMS and SMS Gateway then sends the Reply SMS back to the Application.
In this model SMS Gateway/Aggregator can only be able to get response back from the subscriber if it has connectivity with the SMSC of the Subscriber Operator. I mean any SMPP/CIMD/HTTP connectivity.
Note: So, this method is mainly used for sending bulk messages, instead of any Interactive Applications. And if you want to develop any application with only SMS Push, this is the simplest and cost effective method.
B) ESME way:
Here, instead of connecting to the SMS Gateway/Aggregator your SMS application can directly connect to the operator SMSC. So, you need to connect to SMSC to send message and this connection will be on a protocol called SMPP/CIMD/HTTP. You will become an EMSE (External Short Message Entity) for the SMSC. Operator will provision your application as an ESME on its SMSC with System ID/Password and Shortcode.
You need to first connect to SMSC over SMPP (TCP/IP) using an allocated System Id and Password. Then your application can send message(s) to the subscriber via SMSC. Subscriber in terns can send the reply back to your application or can request for Subscription/Content etc. by sending specific Keyword to your Shortcode. This will reach to the SMSC from Subscriber handset and SMSC will deliver the message to your application.
Note: Here, though push SMS can work if the Subscribers do not belong to the same operator to which SMSC your application is connected. But, for Subscriber to send message back to your application, s/he should belong to the same operator.
UP.Notify is the precursor push technology and is supported by Openwave
WAP Push is translated to UP.Notify for older Openwave handsets
Up Notify does not allow pushing to all WAP 1.2.1 Handsets(an equivalent Service Indication can be sent to Openwave WAP 1.2.1 handsets)
Prefetch3 and Alerts are the UP.Notify equivalent to WAP Push SL and SI.
Legends:
1 Service Indications are alerts with a click-able link (e.g., "You have a new email, read now?"). For SMS translation, the URL will not be click-able due to limitations of SMS. The other push defined content types do not have presentation text associated them and are thus not readily translated.
2 Service Loads are alerts that also automatically delivers the content to the handset without user interaction. It is similar to Service Indication but removes the need for the user to confirm that s/he wants to load the content. Use of Service Loads depends on the application and the desired user experience.
3 A "prefetch", also known as "pull notification", allows content to be automatically loaded in the handset cache so that the user has immediate access to the push message when viewed.
If you have a Mobile Number with an XYZ operator and want to switch to ABC operator without changing your number, MNP (Mobile Number Portability) is the answer. Now, say my mobile number is from Airtel and I want to take a better offer from Hutch. But when I switch to HUTCH, I need to take a new number from HUTCH and I need to change my old good number which is known to all my friends and relatives! With MNP in place you have the freedom to switch to operators without changing your number.
As Govt. has announced that they will launch MNP in major cities in
For example, I am planning to shift my Mobile Number from Airtel to HUTCH to set my caller Tune to "Maa-from Tare Zaamin Paar" as it is not available in Airtel. It sounds funny! But you can try all your options to get better services while MNP knocks your door. Till then Keep Enjoying...
Now why is this? Why are we being victimized in this way? Ask to your self concise and you will get the answer. Please don’t curse the developers or banks alone. If there were no unprecedented demands for such flats there should not be so many constructions going on and if there were no madness among us to buy the flats in this double price, then there should not have such price tag for these low quality flats! It is as simple as you can understand my friend! In reality, we like to curse others for the situation we have created by our own bloody hand!! It’s very simple! So, please justify your spending dear IT friends and those of you in the society have more money. Because, most of us lead a middle class life and can not survive such spending culture and creation of unjustified pricing. This can have serious consequences to our economy as a whole, with a bang of “Financial Meltdown”!!
When I talk about illogical spending spree of IT professional I also like to take note of another habit (bad-habit) of regular IT professionals preferring to eating outside. They prefer to eat outside not because they like that food but they are too lazy or disorganised to cook. I found lots of my friends or their friends converted their kitchen into Junk Room!
Another consequence of IT society is not ignorable. Ya, I wanted to mention about the growing number of students are making there mind to come to this industry for job. They just get relaxed and happy with a mediocre IT job in respect to their great potential in respective field of science, commerce or mathematic. Everybody just wants to start a career in IT. Few most critical factors towards this changing phenomenon are: 1) Family pressure to earn competitive salary and lifestyle 2) Social discrimination based on money status rather than knowledge and educational status 3) Illogical and very low salary structure for these fields.
The dangerous consequences of these attitudes surely lead
Let’s come back to
And did anybody ever thought about the illogical price rise in BMTC tickets! Minimum fare is increased from 2 to 5 Rs. and price tag of a daily pass is increased by just double! As an IT/ITES/BPO professional you may not be feeling the heat because of high value salary slip or your big MNC provides comfortable pick-up and drop in luxuries vehicle. What about the common man (Common middle class population and lower middle class people who are the main travelers on these buses)? I would like to ask to the BMTC authorities: “Sir, do you think these fares are in any way been increased keeping in mind about the common man?” My wife keep asking me this question! Oh! God…save us!
I am ending this article by telling you a story or you can say a realization. I was in a trip to Malpe, near Mangalore. Malpe is a island and we were figuring out whether we can get certain item out there or not. We came to know that we will get those things there but will be costing just double of the regular price. I felt very happy that we will get the things out there and it will only cost 30-35 Rs. (without thinking once also that it will cost just double!!). One of my friend, Narayana, told me, “Samir, did you ever noticed that you are going to spend just double of the actual price?”
I was ashamed and said to myself: “Oh! God! Help myself!”
My intension for writing this series of articles is not to blame anybody, but ourselves. My intension was to make us understand that as a representative part of Indian society we should be more responsible in our daily terms to realize the great Indian dream! And at last I want to leave you all with an amazing quote of Karl Marx(which I have receive as FWD mail from my friends)written way back in 1867, which will inspire my Great Indian Dreams-II and keep you all busy for few minutes:
"Owners of capital will stimulate the working class to buy more and more of expensive goods, houses and technology, pushing them to take more and more expensive credits, until their debt becomes unbearable. The unpaid debt will lead to bankruptcy of banks, which will have to be nationalized, and the State will have to take the road which will eventually lead to communism"
-- Karl Marx, Das Kapital, 1867
