Multimedia Messaging Service
Multimedia Messaging Service (MMS) is a 3GPP mobile messaging standard that supports picture messaging, sound, graphics and voice. Unlike EMS, MMS does not draw on established messaging technology (such as SMS). Instead, it requires network operators to deploy new infrastructure, including a multimedia messaging service center. It uses a wireless data bearer to deliver messages and requires MMS functionality in mobile devices. The MMS standard was defined jointly by the 3GPP (TS 23.140) and the Open Mobile Alliance (OMA), incorporating the WAP Forum. MMS supports many features that could not be delivered using established mobile messaging standards.
