How to skip sms from going to inbox

[JKDESAI]

I want to filter some sms on some precondition & don't want to move to the inbox. For handling incoming sms i have reffered following KB article:

How_To_-_Use_SMS_to_notify_an_application

In this article there is written, If we dont want to appear the sms into the inbox, then we have to make it system messege by setting the Protocol Identifier & digital Coding Scheme.

But i don't understand how to do all that. Can anyone explain in brief what to do?..My aim is that i jus dont want to move some perticular sms messeges to the inbox.

For sending & receiving sms manually i am using sms server provided by JDE.
