Hello. I have been asked to research on the posible solutions on the implementation on a SMS sistem. Basically, we need to develop an application where our field personnel would send a SMS to an *XXXX number to start a transaction, then, the SMS server would respond, asking for the username, the field guy would respond, the SMS server would again respond asking for the password, the guy would respond, and then the SMS server would ask the product code, the guy would respond, and the SMS sever would respond with the current price. In brief, being G the "field guy" with the mobile phone, and S, the SMS server:
G -> S: *XXXX hello
S -> G: enter userid
G -> S: user1
S -> G: enter password
G -> S: xxxxx
(after checking the user/pass is ok)
S -> G: enter product code
G -> S: 00032
(after checking the code 00032 price)
S -> G: $50
this is basically the idea. So de questions are:
1) how can i simulate this between a PC and a mobile phone in the easiest and fastest way, so i can show a proof of concept.
2) how would i really need to know/do to implement this type of system?
THANKS A LOT.
