openraw PDU mode for SMPP
0%
Description
it has came up several times that the conversion from SMS-PDU on the Um/L3 interface towards SMPP is not really wanted/needed in case of an external SMSC that doesn't want to look inside the messages. Rather, the conversion is possibly making life just harder.
So ideally we would be able to add a mode to SMPP in which all MO-SMS are simply passed through 1:1 without transcoding the user_data.
I guess all we need is some way (like a VTY config) that makes sure smpp_determine_scheme() returns a newly-defined "proprietary" data coding scheme in SMPP, and at the same time set *mode = MODE_8BIT, at which point the user_data will be a simple memcpy of the original user data.
The problem is that while doing that, we probably loose the original DCS as it was set on the L3 of the GSM interface...
