Hi, Yes i m also think that the message size is a major design issue in this. I was thinking of limiting the payload size.Because IMO most of the practical scenarios the maximum payload size given in SMPP will be sufficient.
I think aggregating messages will be harder since we have no control over the other side. I hope i'll be able to get you ideas in the future while i m doing the project thank you, Charith On Sun, Mar 22, 2009 at 8:36 PM, Ajith Ranabahu <ajith.ranab...@gmail.com>wrote: > Hi Charith, > > This is a very good idea indeed.
