TAMPA, Fla. – Nov. 12, 2012 – Syniverse today announced an agreement to provide its IPX Network and Diameter Signaling Service to leading Hong Kong mobile network operator SmarTone. The agreement supports SmarTone’s participation in Syniverse’s comprehensive LTE roaming trials, which allow the operator to test end-to-end LTE roaming functionality and launch commercial service with partners globally.

“It is critical that mobile service providers anticipate and prepare now for the technical complexities of LTE roaming so that end users enjoy a seamless experience during the transition from legacy services to LTE,” said Jeff Gordon, President and CEO, Syniverse. “The Syniverse LTE solutions enable SmarTone to test, resolve and guarantee the quality of its LTE roaming processes. In addition, SmarTone’s integration of our IPX network is a critical step as it offers LTE interoperability to its end users.”

Diameter Signaling Service is a leading-edge solution that addresses routing, interoperability and mediation services to enable seamless LTE roaming. SmarTone is among the more than 80 operators worldwide that are connected to Syniverse’s IPX.

The solutions SmarTone has chosen also enable them to join Syniverse’s LTE roaming trials among seven Tier 1 mobile service providers from around the globe. Syniverse’s end-to-end LTE roaming testing environment allows mobile service providers to test device authentication and signaling on LTE networks as well as critical LTE roaming functions, such as real-time intelligence and wholesale clearing and settlement.

“During our LTE rollout, we must continue to deliver a high level of service and ensure our networks interoperate flawlessly to provide the ubiquitous reach our end users have come to expect,” said Stephen Chau, CTO, SmarTone. “With Syniverse’s IPX and LTE roaming solutions, we are able to address the challenges of LTE interoperability and interworking now to ensure the best quality of experience for end users once LTE roaming is launched commercially.”
