MM4 is typically used for connectivity between operator MMSCs. When you are making an MM4 connection to an MMSC, the MMSC typically is also configured to make an MM4 connection to deliver messages back to you (via MM4/SMTP). | |||

SMTP most certainly is used for both sending and receiving e-mail. Think like a server, not a client. (Keep in mind that MM4 is intended for use for connections between MMSCs, where both are effectively servers.) When you are making an MM4 connection to an MMSC, the MMSC typically is also configured to make an MM4 connection to deliver messages back to you (via MM4/SMTP). You accept an SMTP connection to receive this message. | |||

MM4 is intended for connections between MMSCs. Unlike MM1, a mobile phone client would not use MM4. For the sake of trying to clarify this. Let's say that Mobile A is on operator A, and Mobile B is on operator B. Operator A and Operator B are using MM4 to interconnect their MMSCs. Mobile A opens up a GPRS connection, and performs an HTTP or WSP POST of an MMS message (m-send.req) to operator A's MMSC. Operator A's MMSC sees that the message is addressed to Mobile B, and Mobile B is a subscriber of Operator B. Operator A's MMSC sees that it uses MM4 to connect to Operator B's MMSC. So it, opens up a connection, and uses an MM4/SMTP dialog to transmit the message to Operator B's MMSC. Operator B's MMSC publishes a dynamic link for the MMS message content, and sends an MMS notification to Mobile B telling it that it has an MMS message that can be retrieved by the specified URL. | |||

Oh, i see ,i see. thank bryce for your patiently reply! for client, client need only send/receive mms by wsp-post/get. which don't need to care the MMx interface. | |||

Right, an MMS client for a mobile phone only needs to be concerned with MM1 (which is the WSP-POST/GET that you are familiar with). | |||
