Comfone MMS Hub facilitates the delivery of MMS traffic between mobile operators and includes access, relay, bulk file production, online reporting and financial settlement. IP access, DNS and routing for the transport of MMS is enabled and MMS Interconnection is allowed between different mobile operators through the Comfone MMS Hub's Relation Management and Mobile Number Portability Check.

• DNS: The DNS (Domain Name Service) enables the resolution of URLs into the IP address of the destination MMSC. The DNS is set up according to GSMA guidelines and is a mirror of the .gprs
  Root DNS of the GSMA. Synchronisation at regular intervals
  guarantees that the DNS database is up-to-date.
• Routing: The Comfone MMS Hub’s interface with other MMS service providers uses BGP, allowing dynamic routing based on Autonomous System Numbers. To allow the transfer of messages between PMNs connected to different MMS Hub providers, the Comfone backbone is interconnected to other MMS hub providers at the GSMA peering points.
• MMS delivery: The MMS Hub provides MMS delivery functionalities which offload tasks from the operator MMSC. MMSs are sent from the originating operator MMSC via MM4 interface to the MMS Hub. From there, they are processed according to subscribed business logic and forwarded to the recipient operator MMSC. White lists allow the administration of MMSC relations, halting the flow of traffic that cannot be billed and preventing spam attacks on the destination MMSC.
• Online reporting: Comprehensive reports provide information on service usage and function as a valuable marketing summary of an operator’s outbound MMS Interworking traffic. MMS Hub reporting is available via Comfone’s online reporting portal.
• Quality of Service: Quality of Service parameters provided by the Comfone MMS Hub guarantee DNS and peering availability. The system’s architecture is fully redundant and designed for high availability in accordance with industry standards.
• Class of Service: The Comfone backbone is a fully MPLS enabled (Multi-Protocol Label Switching) IP network with Class of Service (CoS). CoS allows the prioritisation of IP traffic depending on the type of service that is being employed. Additionally MPLS provides optimised routing and reduced latency.
• Security: The MMS Hub machinery is fully protected within a secure installation with standard IP security architecture and firewalls. The network on which the MMS Hub is implemented is completely separate from the public internet and the public IP addresses used are not advertised outside the GSM community. Data encapsulation is not required because the Comfone MMS Hub is built on a private network with built-in security.
