What Is an MMSC?
• The Multimedia Messaging Service Center (MMSC) is the store and forward network element that delivers the MMS messages from the sender to the recipient. The MMSC concept is similar to an SMSC, that is, the server stores the message only for the time required to find the receiving device. After the receiving device is found, the MMSC immediately forwards the MMS message to the recipient and the message is deleted from the MMSC. Thus, the MMSC is not a mailbox server, because it does not store the message if the message can be delivered to the recipient device. The MMSC uses an integrated WAP interface to interconnect to the wireless data network. An MMSC may also have an e-mail interface. The Nokia MMSC also provides interfaces for the billing system, other operator’s networks, operation & maintenance, network management, and an Application Programming Interface (API) for MMS applications.
