I'm developing a MMS service and have some questions.
I use GPRS modem to send MMS, whether the step like below(I had connected the GPRS modem to WAP Gateway used ATD command and got a IP address):
1、build a MMS message
2、encapsulate the MMS message to WSP Post PDU
3、encapsulate the WSP PDU to WTP PDU
4、encapsulate the WTP PDU to UDP packet
5、add IP header and build a IP packet
6、build and send the PPP frame
Whether the step like this ? Thanks.
