Hi; Where would I be able to find information on how MMS push messages are built up. I have spent some time in decoding a MMS message, but I haven't been able to find any documentation on PUSH headers, message assembly etc. | |||

Hi, You'll want to consult the WAP specifications published by the Open Mobile Alliance at http://www.openmobilealliance.org. Specifically the WDP protocol defines the low level WAP protocols, and defines how they are implemented on top of an SMS bearer. The WSP protocol defines connectionless push over WDP. The MMS Encapsulation protocol defines the MMS content formats. Of course, you've got to deal with the notification message which gets sent out in a WAP push, and the MMS message content URL that the push points to, which itself is encoded using the MMS Encapsulation protocol as a header, with the body of the MMS message encoded as "application/vnd.wap.multipart.related" or "application/vnd.wap.multipart.mixed", as defined in the multipart encoding section of the WAP WSP specification. There may be other specifications in the WAP protocol set that would be of use to you, particularly in the push area ... but most of those specs relate more to the format of specific push content types (service indicator and service load), and interfaces between an application and a push proxy gateway, which probably don't apply to what you are trying to accomplish. Of course, you can also use the Now SMS/MMS Gateway to generate many of these types of messages. Good luck! -bn | |||

Assuming that you have a WAP push proxy gateway that supports the Push Access Protocol (PAP), and is flexible about the content types that it supports ... you would generate a PAP request similar to a WAP push for an SI (service indication) ... however instead of having the 2nd part of the MIME content type being "text/vnd.wap.si", it would be "application/vnd.wap.mms-message". The content would be the binary format of an "m-notification-ind" message as defined by the OMA's MMS Encapsulation specification. In the next release of the Now SMS/MMS Gateway, we have an option to send MMS notifications through a WAP push proxy gateway using PAP instead of direct SMS. The interface is described at the following link: Routing MMS Notifications via a WAP Push Proxy Gateway -bn | |||

I wanted to find out the different formats for MMS messages. ther are different phones having diff resolutions etc.. so what are the different specs and also is there an optimum size / specs? Same for video clips. | |||

How could I get the MMS notification PDU over SMS using a Nokia 6610 phone as a modem (this modem would be the receiver of the message)? Is it possible using AT commands or any Java library? Thanks. | |||
