Sorry for my poor english . I am developing a mms client at China. I can send mms thorough wavecom modem ok, but i don't known how to receive a mms.

When I use wavecom modem send mms to Nokia 7650 through wap wsp, anything is ok. But when i use nokia 7650 send mms to wavecom modem by wap wsp, i can't get mms notification msg.

I don't known the mms income notify is come from sms or other way. If i get the mms url then i known how to use wap wsp to get it, but i don't known the mms url how to send by mms notification message.

Thanks for you help.

Hi Eric,

The MMS notification is going to come in through SMS. Specifically the MMS notification arrives as the content of a WAP push message. The WAP push message arrives via SMS. (It could also conceivably arrive via IP, but don't expect that in current generation implementations.)

The MMS notification message is encapsulated in a WAP push message.

Consult the WAP Wireless Datagram Protocol (WDP) specification, and the section on "WAP over GSM SMS" for information about how WAP packets are encoded over GSM SMS.

Then consult the WAP Wireless Session Protocol (WSP) for the PDU format of a connection-less push. (Section 8.2 for "Protocol Data Unit Structure", and Section 8.2.4 for "Push and Confirmed Push Facilities".)

Then consult the MMS Encapsulation Specification for the format of the m-notification-ind message that is the MMS notification.

All of those specs are published by the Open Mobile Alliance (http://www.openmobilealliance.org).

Basically, the WDP spec is going to tell you about the encoding of the SMS User Data Headers (UDH).

The WSP spec is going to cover how the data of the SMS message is formatted. You'll have WSP headers, with the MMS encapsulated message as the content.

Between those specs, and the following message link, I think you'll be able to figure it out:
