MM10 (application id: 16777226)

The MM10 interface facilitates communication between the MMS Relay/Server and the Multimedia Service Control Function (MSCF). The primary function of the MM10 interface is to manage the processing and delivery of multimedia messages (MMS). 

MM10 interface workflow:

1. Initiation: 
   • When the MMS Relay/Server receives a multimedia message from a user, it may need to query the MSCF for further processing instructions. This is done by sending a Message-Process-Request command to the MSCF via the MM10 interface. 
2. Processing by MSCF: 
   • Upon receiving the Message-Process-Request, the MSCF processes the request based on the provided data. It may determine the appropriate routing address, modify the message content, or apply any other required processing steps.
3. Response to MMS Relay/Server: 
   • After processing, the MSCF sends a Message-Process-Answer response back to the MMS Relay/Server. The response includes a result code that indicates whether the processing was successful, partially successful with modifications, or unsuccessful. 
4. Action by MMS Relay/Server: 
   • Based on the response from the MSCF, the MMS Relay/Server takes the necessary actions. If the processing was successful, it continues with the delivery of the multimedia message. If modifications were required, it applies these before delivery. In case of rejection, the message is not delivered, and appropriate feedback is provided to the sender.
