How TNS Wireless Transport Works

1. Using the roamer’s unique identifier (MIN for ANSI-41 and IMSI for GSM), the MSC/VLR launches a message to the TNS SS7 network for routing.

2. The TNS network performs the appropriate translations and screening, then routes the message to the home carrier network.

3. The roamer’s home MSC/HLR validates the roamer and sends the appropriate profile information to the serving market to allow service to continue.
