Interoperability system between MMS messages and SMS/EMS messages and associated exchange method

摘要

An enhanced message service (EMS)/short message service (SMS) short message received through a mobile radio network, are transmitted to a message gateway. The message gateway converts the EMS/SMS short message into multimedia message service (MMS) message, and transmits the converted message to an MMS server which in turn transmits the message to destination terminals. Independent claims are also included for the following: (1) message system; (2) short message service short message; and (3) enhanced message service enhanced message.
