TNS supporting US outbound roaming traffic to Caribbean

Transaction Network Services (TNS) has revealed a series of investments in the TNS-powered CCA LTE Roaming Hub (Hub) which increases its Caribbean coverage to more than 17,000 square miles and introduces an innovative new GPRS Tunneling Protocol (GTP) Proxy facility for enhanced efficiency, the company said.

Several Caribbean operators that cover the Dominican Republic and the Bahamas have joined the Hub as roaming partners. The Hub, through existing carrier members, also supports US travelers to Jamaica, the Cayman Islands, Anguilla, Antigua, Barbados, Dominica, Grenada, Saint Kitts and Nevis, Saint Lucia, Turks and Caicos, Saint Vincent, and the British Virgin Islands.

TNS´ new Hub GTP Proxy facility has been designed to manage the routing of GTP-C and GTP-U traffic and map the allocated IP addresses to a roaming partner´s packet gateway and GPRS support node. A GTP proxy allows single IP connection and less testing required for individual operators.

The CCA LTE Roaming Hub provides operators with a large, seamless footprint that supports efficient VoLTE, enables roaming to and from 4G LTE without circuit-switched fall back to 3G, and provides inbound roaming revenue opportunities. Within the US, the coverage offered is more than a regional operator could get from any individual Tier-1 operator.
