Routing system for inter-operator multimedia messaging (MMS) traffic

摘要

The system has a domain name server (DNS) for transmitting several Internet protocol (IP) addresses from a multi-media messaging center (MMSC) of a destination user, if a request is provided from a multi-media messaging service (MMS) relay station or transmitting user during direct connection with the destination user. The DNS transmits the IP addresses of the MMS relay station, if the request is provided from other different users.
