The TNS ANSI-41 Wireless Transport service provides inter-switch signaling necessary for seamless roaming, including call validation, cross-protocol roaming capabilities, SMS roaming, and automatic call delivery.

TNS allows authentication of users on the network, identifies the appropriate destination for routing, delivers the message to the MSC/HLR for validation, and accepts the response to complete the registration.

TNS has extensive connectivity to tier one CDMA carriers providing direct access to roaming partners worldwide. For roaming partners not directly connected to the TNS network, TNS provides seamless connectivity to other roaming service providers. 

For international roaming, TNS provides seamless connectivity to the TNS Intelligent Message Processing gateway.

Our seamless roaming solution, when combined with other TNS data-mining and roaming services, such as the TNS Roamer View service, provides real-time information for troubleshooting and monitoring as well as useful reports for strategic planning.
