load balancing with SMPP

While using camel-smpp if the message text is longer then 160 chars , it
breaks the incoming messages to 160 char sms's and send it to SMSC. if we
add load balancer , it works on incoming long messages instead of outgoing
160 length sms. for example if i set the load balancing to 5 and incoming
messages length is 800 char. it will send sms to smsc at 5*5=25 messages .
but it should not send more then 5 as per the load balancing . any help will
be appreciated.
