Subject Re: [Axis2] SMS transport for axis2

Hi Charith,

This is a very good idea indeed. As many pointed out, there are
immense benefits in doing this and it is indeed great for a GSoC.

I think Sagara has a good point. Since there is a character limit per
message you need to think about how larger payloads can be transfered.
For cell phones I remember there was a format where you can send one
single message consisting of up to some max number of separate
messages. I remember this to be Nokia specific thing since they
appeared messed up in the old Ericcsson I used to have.[ Am writing
this mail offline so can't google :(  Not sure whether it was adopted
as a standard ] . You can definitely take a look at such things.
Ultimately if you can comeup with a protocol binding (such as the WSDL
bindings for HTTP or SMTP) that would be an ideal outcome. Such a
binding would at least become a de-facto standard if you are
successful :)

Guys that have more knowledge in SMS can help out here, Can SMS
transfer binary ? [I doubt whether it can. It seemed to be only
ASCII]. If so you can think of more space efficient XML serializations
such as fastinfoset.

Just some ideas
