APPARATUS AND METHOD FOR INTERFACING MMS AND IMS MESSAGING SYSTEMS

摘要

A system, method, and interworking function for interfacing the Multimedia Messaging Service (MMS) and IP Multimedia Subsystem (IMS) messaging systems. When an Multimedia Messaging Service Center (MMSC) receives an MMS message, the MMSC determines whether the message is addressed to an MMS user or an IMS user. If addressed to an MMS user, the MMSC routes the MMS message to an email server for forwarding to another MMSC. If addressed to an IMS user, the MMSC routes the MMS message to the interworking function. The interworking function converts a destination address in the MMS message to a destination address for the IMS user that is routable through a Session Initiation Protocol (SIP) core network. The message may be mapped to a SIP MESSAGE format or an MSRP format and sent through the SIP core network to the addressed IMS user.
