Hi Guys,

I work for WWF and recently I was contacted by a colleague from Portugal. For one of our upcoming events, Portugal telecom has come forward to give us a short code number on which we can do some fund raising. They have told us that when a donor texts a message to the number, they would be charged a certain amount and the money will be transferred to us; more importantly, they will communicate the SMS to us. The channel will be UCP over TCP/IP. 

I have done simple java applications that take care of reading sms messages from a GSM device and broadcasting messages by connecting to bulk sms gateways. I use an open source library called smslib.

Can someone tell me what kind of setup should I have to read messages from this telco? I am not even sure what questions to ask. 

This is my first question to the group (Although I read all of the conversations eagerly). Please excuse me if this is not the right forum for my question.

Thanks
Hariharan

You might already know that SMSC (SMS Centre) is a special server in Telco's network which can connect to application-servers, usually over TCP/IP that can send/receive SMS's, and these SMS's are called A2P or P2A (A: application, P: person). Since this interface was not standardized by GSM, SMSC vendors invented their own proprietary application-level protocol for this communication. UCP happens to be one such protocol, but SMPP is a newer, more open similar protocol. There are various types of API's implemented to pull/poll (or push for send) messages, and some event-driven API's exist as well.

Not sure if smslib supports UCP, it as well might, not sure. However the fundamental logic is similar.

http://www.kannel.org (check for UCP implementation)

Note that SMPP has a SMPP-based SMSC-simulator, with which one could test their application. Not sure something like that exists for UCP.
