Portability-corrected MMS Addressing

When an end-user dials an E.164 number to send an MMS message, Carrier-ENUM provides the standardized infrastructure for the discovery of the MMS service associated with the dialed E.164 number regardless of whether or not the number has been ported. The role of a Carrier-ENUM infrastructure in the delivery of cross-operator MMS services is well defined in the relevant 3GPP, 3GPP2, GSMA and 3G-Americas technical specifications and implementation guidelines:

For more information, contact NetNumber's Business Development team and request a copy of the white paper: “Cross-Operator MMS Service Discovery”. Specific issues addressed in the document include:

• Carrier-ENUM implementation that dramatically simplifies the addressing of IP-based services like MMS and IMS across multiple technology environments (GSM, CDMA and Fixed-line) and across multiple portability regions/countries.
  
  
• Next generation address resolution infrastructure that an Operator can deploy as a stand-alone network component to be leveraged by any number of application services.
  
  
• Addressing infrastructure that is directly aligned with existing ITU and country-specific number assignment regulations and number porting policies.
  
  
• Solution that enables a single Operator to start using ENUM on a stand-alone basis without waiting for other Operators in a country to finish deploying an ENUM infrastructure.
  
  
• Architecture that enables an Operator to leverage number-block and portability data sources already available in the Operator’s network to provision its local ENUM database. No requirement exists for utilizing any centralized ENUM registry/registrar services.
