The VoLTE or Voice over LTE (News - Alert) Interoperability test event included participation from Stoke Inc. Stoke’s Security eXchange is a standalone high performance gateway which was a part of the interoperability event. Secure end-to-end LTE communications are needed in VoLTE Interoperability testing. This was successfully identified by Stoke. The company also proved that the most sensitive mobile services can be handled by IPsec. Stoke (News - Alert) is a mobile broadband developer. The VoLTE Interoperability event was hosted at the Vodafone Centre for Test and Innovation in Dusseldorf.

Practical LTE network use cases were built and validated with help from Stoke. These included use cases like secure association and encryption of VoLTE traffic from the radio access network to the evolved packet core. Recommendations for deployment scenarios were also made by Stoke.

Validating the GSMA’s (News - Alert) technical recommendations for IMS-based VoLTE was the main focus of the event. Best practices for VoLTE deployment strategies were also established. These strategies were established for LTE/EPC/IMS technology. Planned heterogeneous LTE network deployments will mostly require scalable encrypted communications function. IOT test scenarios for this function were developed by Stoke.

In a release, Dave Williams, CTO, Stoke, said, “We are excited to be part of the MSF's efforts in applying the industry standards set by 3GPP to actual use cases, leveraging our ground-breaking experience from live deployments.”

According to Williams, Stoke is aware of the growing industry focus on this main requirement. Stoke is pleased that it has successfully contributed to this aspect of the MSF testing.

Scalable encryption solutions, especially small cell deployments are important for LTE communications. Awareness in this regard is being created by Stoke as traffic backhaul services cannot be always ‘trusted’ in small cell deployments.

Williams said, “Through the MSF testing, our goal was to prove to mobile operators that, with the right standalone platform, IPsec imparts no additional system latency, no throughput performance penalty, and ensures subscriber, network and services integrity.”

President of MultiService Forum (News - Alert) or MSF, Kyu-Ouk Lee welcomed Stoke to the MSF. According to Lee, a valuable contribution to MSF’s ongoing interoperability program is being made by Stoke with its knowledge, experience, and enthusiasm.
