Dear All,
We
One of the carriers we are working with asked us to send them 4 custom
TLV's in order to implement billing services.
TAG: MAS_APP_ID, id=0x1401 Integer(2)
LENGTH: Length of value in octets // Integer(2)
VALUE: 1-255 // C-Octet String
TAG: MAS_SVC_ID, id=0x1402 Integer(2)
LENGTH: Length of value in octets // Integer(2)
VALUE: 1-255 // C-Octet String
TAG: MAS_CONT_ID, id=0x1403 Integer(2)
LENGTH: Length of value in octets // Integer(2)
VALUE: 1-255 // C-Octet String
TAG: MAS_SVC_ID, id=0x1404 // Integer(2)
LENGTH: Length of value in octets // Integer(2)
VALUE: 1-255 // C-Octet String
I've been crawling the source and reading the lists archives, and I've
found that there's not a simple way to implement it without touching
the source code.
The question is, how could I implement this on the source code? What I
need is to be able to send this 4 TLV's on the submit_sm PDU and
ideally I should be able to set the values from the sendsms interface.
I already added this to smpp_pdu_opt.def:
#define SMPP_mas_app_id 0x1401
#define SMPP_mas_svc_id 0x1402
#define SMPP_mas_cont_id 0x1403
#define SMPP_mas_cont_desc 0x1404
and this to smpp_pdu.def:
PDU(mas_app_id,
0x00001401,
HEADER
NULTERMINATED(mas_app_id, 255)
)
PDU(mas_svc_id,
0x00001402,
HEADER
NULTERMINATED(mas_svc_id, 255)
)
PDU(mas_cont_id,
0x00001403,
HEADER
NULTERMINATED(mas_cont_id, 255)
)
PDU(mas_cont_desc,
0x00001404,
HEADER
NULTERMINATED(mas_cont_desc, 255)
)
I've recompiled and everything seems to be working as before.
Am I on the right path?
What I think I'm missing (please correct me if I'm wrong is):
1. How do I include this new TLV's on the submit_sm PDU?
2. How do I add new parameters to the sendsms inteface?
3. How could I _only_ add this TLV's when the parameters are defined?
I don't want to break things with other carriers, this should only be
passed to this particular carrier.
Any hints will be thoroughly appreciated. :)
Best regards,
