LTE roaming is a major complex issue for telecom operators. Several billing and roaming vendors are in the process of launching a number of solutions to assist mobile broadband players.

Tekelec claims that its DSR is providing the diameter signaling hub for Telstra Global’s IPX service announced last month. It enables the secure exchange of authorization, authentication, billing, charging and network policies that use the diameter protocol to maintain subscribers’ LTE services while visiting international markets.

These solutions are important as mobile operators are examining how to maximize the benefits that LTE networks provide, and international roaming is the first step.

“Tekelec is a leader in this space, with the scalability, security and vision for us to support the region’s LTE needs and capitalize on increased international mobility and exploding mobile data consumption,” said Tejaswini Tilak, global head of Carrier Services at Telstra Global.


Telstra Global IPX Service offers a platform that enables mobile operators to introduce new services and applications, to take advantage of ever more popular capabilities such as mobile gaming and video streaming with superior end user experience.

It is provided over Telstra Global’s scalable and managed IP MPLS core network which maximizes traffic on both legacy and new mobile platforms, allowing Telstra Global to partner with mobile operators that have already embarked on or are heading towards their LTE journey.

According to Parks Research, 53 percent of the world’s 4G/LTE subscribers by the end of the year will be in the Asia-Pacific region.

“LTE will revolutionize mobile data business models around the world, and one of the building blocks is a trusted IP exchange. Telstra Global’s demonstrated leadership and innovation will give service providers new capabilities to increase their service offerings and meet subscriber demand for LTE services,” said Tekelec CTO Doug Suriano.

According to a report from Exact Ventures, Tekelec leads the diameter routing market with 19 announced customers and an estimated 75 percent to 85 percent market share.
