FREEHOLD TOWNSHIP, New Jersey, October 26, 2011 /PRNewswire/ --

Traffix Systems, the Diameter control plane experts, contributed Diameter routing support with its DRA in the VoLTE (Voice over LTE) Interoperability Testing event that was organized by the MultiService Forum (MSF) and backed by the GSMA, the association representing the interests of mobile operators worldwide. The test event held in September 2011, backed by the GSMA as part of its VoLTE initiative, focused on validating key network interfaces to ensure multi-vendor deployment strategies for LTE/EPC/IMS technology and setting best practices for LTE deployment strategies.

The Traffix expert team demonstrated core Diameter routing, bridging of Diameter interoperability gaps between vendors, LTE roaming, security and other interconnect use cases, utilizing dynamic policy control between home and visited networks employing DRAs (Diameter Routing Agents).

"Traffix participation with its Diameter platform Signaling Delivery Controller (SDC) succeeded in showing the central role of DRAs in LTE networks," said Lenny Ridel, CTO of Traffix. "We validated roaming scenarios as specified by GSMA PRD IR.88 (LTE Roaming Guidelines for VoLTE S6a and S9 interfaces), and the MSF inclusion of DRA technology within a single PLMN. The SDC also provided protocol normalization for Diameter messages to support interoperability."

"We're pleased to welcome Traffix to the MultiService Forum," stated Kyu-Ouk Lee, MSF President. "The knowledge, experience, and enthusiasm that Traffix brings to the MSF will make a valuable contribution to our ongoing interoperability program, and we welcome its contribution."

The market leading Traffix Signaling Delivery Controller (SDC) consolidates Diameter Gateway, Diameter Load Balancer, and Diameter Router solutions on one unified platform. Traffix will continue to participate in building and validating practical LTE network use cases in industry forums for deployment scenarios with the SDC.  

About VoLTE IOT Event 2011

The MSF hosted the VoLTE IOT 2011 Event in the Vodafone Centre for Test and Innovation in Dusseldorf and the China Mobile Research Institute Lab in Beijing in September 2011. The event is backed by the GSMA following the launch of its global VoLTE initiative in 2010, which is supported by more than 40 leading organizations in the mobile market. The event builds on the major success of the previous Global MSF LTE Interoperability Event that took place during March 2010 and reflects the industry's drive to continue to deliver major carrier driven events that benefit all its members in their quest to keep pace with an ever faster moving industry. The MSF VoLTE Interoperability test event focused on validating core network interfaces to ensure multivendor deployment strategies for LTE technology and validated the MSF physical scenarios developed to incorporate 3GPP LTE/EPC technology and the GSMA's technical recommendations, focusing on Voice over LTE, with the support of China Mobile and Vodafone.
