How does SMS Premium Voting works technically?

We are exploring the SMS Premium Voting similar like American Idol/Big Brother etc etc. How does SMS Premium Voting 开发者_运维技巧works technically? We are interested in how the data collected as far as I understand the third party company will collect the billing data from each Telco companies. Then it consolidate into a single data mining. Is this the right approach?

Or is it possible to get data from the destination number (the thing is we don't know how does it work so I don't know if this is possible or not).

We are actualy programmer and trying to get this data voting collected centrally or possibly raw data of the SMS but need more information on how does thing works.

I am appreciated your comment or feedback.

Thank you

One way this works is that the company that owns the number (either telco or a third party with agreements with telco companies) have a service set up so that each SMS received results in an HTTP request to a webserver of the cusomer's choice. Simplified "big brother" has a special page on their web site and the telco companies visit that page once for each SMS posting the SMS content. All filtering and calculations are then completed in the code for that page. Naturally you have to makesure that you ignore any requests from unexpected hosts to avoid voting tampering.
