Network
(.gprs)
T-Mobile
Private IP Space
Example utilizes three services:
•
1.
General packet radio service roaming exchange (GRX) offering
2.
CDMA Data Roaming Exchange (CRX) network solution
3.
MMS Interworking Gateway (MMS-IG)
+1-813-451-4824

For Alltel to T-Mobile MMS message, the path would go through the MMS-IG
the NAPTR record returned from the ENUM query could be:
mailto:[email protected]
The MMS-IG would transcode the message and conduct a second ENUM dip
to forward the transcoded message to
mailto: [email protected]

For Verizon to T-Mobile MMS message, the path would go through direct link
the Verizon view of the NAPTR record might look like:

In this example, the T-Mobile MMSC would be responsible for the transcoding
and the entry point could be a different MMSC versus the MMSC
utilized for other GSM providers.

Summary
• Operators may desire a different response from ENUM
depending upon their transport and interworking
relationships with other operators:
– CRX
– GRX
– MMS Interworking hubs
– Private/Direct IP connections
• One goal of Operator-ENUM should be to provide the
operators flexibility to define how they view other operators
and the entry points to those networks.
