How Metaswitch Helps AIS Improve the VoLTE Experience in Southeast Asia

Zenica JoyMay 06, 2017

In the Southeast Asia (SEA) and Oceania regions, Ericsson’s Mobility Report for June 2016 showed that most mobile operators and service providers are transitioning their customers to the cloud and leveraging long-term evolution (LTE) to power their network communications. As the demand for a cloud native, all-IP voice, and messaging communication system continues to grow at a rapid rate, mobile operators and service providers are transforming their networks to enable Voice Over Long-Term Evolution  (VoLTE) services. Through VoLTE, business customers can significantly improve connectivity and experience call quality that is superior to 3G or 2G connections.

As a leading provider of cloud-native communications software, Metaswitch is helping service providers in the Southeast Asian region enable the development and delivery of VoLTE services by deploying Perimeta session border controllers (SBC). The deployment of Metaswitch Perimeta supports VoLTE peering between Thailand’s largest mobile phone carrier, AIS, and other network operators in the SEA region.

Enhancing the Quality of the VoLTE Experience for SEA Subscribers

The extended deployment of Metaswitch Perimeta in Thailand enables AIS to expand their VoLTE service for their subscribers in Southeast Asia.

“VoLTE peering offered by our own network and others will enable the rapid proliferation of VoLTE services in the SEA region,” said Kriengsak Wanichnatee, the Chief Technology Officer at AIS. “Perimeta’s high performance, unsurpassed stability and seamless interoperability with third-party products made our decision to deploy it on our 4G VoLTE network extremely easy. This extension of Perimeta’s role in our network confirms that the platform gives us the confidence and capabilities to rapidly deploy new services and scale quickly as our subscriber base grows.”

With 98 percent nationwide coverage and more than 40 million subscribers, AIS and its subsidiaries provide high-speed mobile network, data communications, international direct dialing, and call center services in various parts of Southeast Asia.

“Innovative carriers such as AIS are aggressively seeking to improve the quality of the VoLTE experience for their subscribers by interconnecting their VoLTE service with other operators,” said Maclean. “Our Perimeta session border controller provides the VoLTE peering and roaming features required by tier 1 mobile networks worldwide, with the virtue of delivering industry leading performance in cloud native, virtualized deployments.”

Metaswitch Perimeta enables VoLTE roaming and peering through its best-of-breed functionalities that include:

  • 3GPP/GSMA standards compliant - all roaming models supported
  • Deep analytics and diagnostics for control and troubleshooting
  • Field-tested session initiation protocol (SIP) interoperability
  • Industry-leading cloud-native SBC gets roaming faster
  • Network-wide licensing ensures optimal use of session investment
