MM1

All you want to know about MM1

This article is not about the M/M/1 model in queuing theory.

MM1 is the interface between Mobile Station (MS) and MMSC. It has been defined by the 3GPP in TS 23.140.

MM1 is used in the following actions:

the sender subscriber sends an MMS to the MMSC
the MMSC notifies the recipient subscriber that he/she has an MMS waiting for retrieval
the recipient subscriber retrieves the MMS from the MMSC
the MMSC notifies the sender that the recipient has retrieved the message
the recipient subscriber manages his/her mailbox in the MMSC (uploads MMS, deletes MMS, ...)

The MM1 interface is based on the WAP protocol. It includes the PAP notifications that are transformed to SMS's by the WAP gateway for the notifications.
