Use of SS7 protocol for mission-critical type SMS transmission - Info requested

[Nicksil07]

Hello,

To begin, I'll just explain that I am just in the very early stages of experimental development of a couple of ideas of mine. This one in particular requires the send/receive of mass SMS messages via mobile devices where receipt and return transmission must be controllable and dependable.

So far, within my research, I know of SMS gateway aggregators and methods of the like. I'm also slightly aware of the international termination model. The latter of the two seem to be what I am looking for. However, in my research, I haven't found much in the way of concrete setup ideas or implementation. I've found countless maps and break-downs, but nothing regarding necessary equipment and proper process of gaining access to the networks or SS7 manipulation.

Ultimately, I need to send a message that I KNOW will be received by the end user at a specific time. I also need to ensure their return transmission is sent to me without any interference (i.e. without having to go through SMSC's of the various providers) I'm under the assumption that I need direct access to the SS7 protocol where I'd be able to manipulate my transmissions to my specifications.

I can understand if I'm not making too much sense here, because in all honesty, I'm in the VERY early stages of development and there are many things I've yet to set in stone, either. I'll be glad to try and specify any point I've laid out here should anyone be willing to help me out with some advice.

I'm looking for advice concerning necessary equipment (i.e. GSM/CDMA modems, switches, server, etc.) The software aspect will be developed by myself, but I would need to know how everything else will work before I can get started on that.

And yes, I completely understand that this avenue has the potential to cost a lot of money and require a ton of time spent in development, but like I said, this is the beginning.

Thank you for your time and any advice.

- Nick

From what i know from work when colleagues using gsm modems, you definitely need to think of using an layer on top of all. A layer of your own that does the necessary checking and acknowledging of transmission and reception. Because gsm or sms does not guarantee anything. Has something to do with time slots and avalable space in the limited bandwidth of the carrier if i remember properly.

A protocol of your own that does the acknowledge checking.

If you have any ppt file we could use on training for editors, we would appreciate if you can made it available for us.
Thank you.

Sms travels on the control signal for cell phones...you need to make sure you won't be taking up so much bandwidth that you interfere with the cell phone getting the communication info from the tower that it needs.
