Due to the rapid growth in subscribers and services, mobile network operators are under immense pressure to offer a high-quality, seamless user experience.

In such a critical market scenario, Starhome (News - Alert), a roaming partner of choice for mobile operators that want to offer end users seamless movement from network to network, is now providing a portfolio of roaming solutions based on Metaswitch’s IP Multimedia Subsystem (News - Alert) protocol software products.

To push seamless mobile communication onto any IP device and to help users to route incoming calls to their IP Soft Phone (News - Alert), GSM phone or both, according to location and their preferences, Starhome is using Metaswitch’s DC-SIP protocol software product in its Mobile2IP solution.

Users who choose to roam are provided with pricing packages and notifications regarding their tariffs and usage in real time with Starhome that uses Metaswitch’s DC-Diameter protocol software product in its Roaming Control solution.

And to allow seamless service orchestration of any existing or future IN/CAP/SIP/IMS services, Starhome is using Metaswitch’s DC-SIP protocol software product in its NG Service Broker Solution that combines Starhome’s Intelligent Network expertise and the 3GPP standards for IMS into a core network element.

For various ongoing IMS research projects, Starhome is also taking advantage of Metaswitch’s flexible IMS protocol software architecture.

“Being able to use a common IMS protocol infrastructure across a broad range of products and across multiple platforms was a huge win for us,” Shlomo Wolfman, Starhome’s COO, said. “Metaswitch’s IMS products are so widely deployed, and have such extensive interoperability exposure, that we could focus on maximizing our products’ roaming capabilities without worrying about connecting to other devices or services when we deployed.”

Based on its N-BASE portability technology for over 25 years, Metaswitch has developed portable network protocol source code. The routing solutions of the company are architected to handle the scale and reliability requirements of the most demanding applications while providing extensibility and a full feature set.

“Having the leading player in roaming solutions select our IMS products is a major vote of confidence,” said Clive Partridge, general manager of Metaswitch’s Network Protocols Division. “We are very happy to be working with Starhome on such leading edge products, and to be part of their roaming services evolution.”

Metaswitch Networks recently acquired service broker solutions provider, AppTrigger, Inc., by signing a definitive agreement, in order to enter the Service Broker market.
