/**
* This is an object that used to communicate with SMPP Server or SMSC. It hide
* all un-needed SMPP operation that might harm if the user code use it such as :
*
*
DELIVER_SM_RESP, should be called only as response to DELIVER_SM
*
UNBIND_RESP, should be called only as response to UNBIND_RESP
*
DATA_SM_RESP, should be called only as response to DATA_SM
*
ENQUIRE_LINK_RESP, should be called only as response to ENQUIRE_LINK
*
GENERIC_NACK, should be called only as response to GENERIC_NACK
*
*
* All SMPP operations (request-response) are blocking, for an example: SUBMIT_SM
* will be blocked until SUBMIT_SM_RESP received or timeout. This looks like
* synchronous communication, but the {@link SMPPSession} implementation give
* ability to the asynchronous way by executing the SUBMIT_SM operation parallel
* on a different thread. The very simple implementation by using Thread pool,
* {@link ExecutorService} will do.
*
* To receive the incoming message such as DELIVER_SM or DATA_SM will be managed
* by internal thread. User code only have to set listener
* {@link MessageReceiverListener}.
