<DIV><FONT face=Arial size=2>SMS is a difficult subject.</FONT></DIV>
<DIV><FONT face=Arial size=2>As was pointed out earlier, you will probably see a
decrease in so called "free" SMS services.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Carriers are moving this year to charge for those
short messages sent between carriers (as is the case for voice
traffic)</FONT></DIV>
<DIV><FONT face=Arial size=2>This basically means that the carrier must charge
the originator of the message or they will suffer a revenue loss by being
charged for the outgoing message (assuming it will go to another carrier
...)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Charging issues are usually the hardest thing to
solve with SMS</FONT></DIV>
<DIV><FONT face=Arial size=2>Different countries have different ideas behind
charging (some enforced by the local laws)</FONT></DIV>
<DIV><FONT face=Arial size=2>eg In Australia, we charge for the submission of
the message and I think in the US, the message is charged for the delivery (with
plans for the first 100 messages being included in the mobile service price
being common)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Once you introduce charging, you need to be able to
verify the charged party to substantiate the charge.</FONT></DIV>
<DIV><FONT face=Arial size=2>This is hard to do (and why Telstra does not
"directly" provide email to SMS)</FONT></DIV>
<DIV><FONT face=Arial size=2>For Jabber to easily integrate into SMS, the
carrier needs to be able to identify the charged party. That may be the sender
or it may be the receiver who turns on (or elects to receive) a chargeable
message. For the receiver based charging, effective filtering schemes are needed
together with both handset (non WAP) and web based control over the filtering
and the ability to turn the message reception on and off.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I can tell you that probably the most used protocol
for connecting to these message centres is SMPP (version 3.3 although a lot can
do 3.4)</FONT></DIV>
<DIV><FONT face=Arial size=2>Telstra uses SMPP to connect to both its CDMA and
GSM networks (and to interconnect between these networks)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
