The ITU Approves WNSRP Standard for Fast-Call Setup Solution Supported by RADVISION
ITU Study Group 16 has approved WNSRP, the only standardized solution that reduces call setup time for real-time 3G-324M multimedia services.
FAIR LAWN, New Jersey, September 6, 2005 -- RADVISION (Nasdaq:RVSN) today announced that the ITU has granted initial approval of WNSRP, a powerful new technical solution that dramatically improves call setup time in 3G-324M multimedia systems.
3G broadband mobile networks and advanced handsets are beginning to make wireless video a commercial reality. The success of emerging video-based services, such as video telephony and conferencing, video-on-demand, remote surveillance, and other real-time services, is impacted by lengthy setup times traditionally associated with streaming video and video conferencing.
WNSRP, supported by major operators, handset manufacturers, and their suppliers, is the only standardized call setup reduction solution for real-time 3G multimedia services in the industry today. RADVISION has been a strong supporter of the new standard and is marketing the first 3G video services gateway incorporating WNSRP available today.
"As 3G video devices proliferate in the market, standardizing a call setup solution becomes even increasingly relevant to market and technical success," said Boaz Raviv, General Manager of RADVISION’s Technology and Networking Business Units. "Other wireless markets have proven that proprietary solutions are not satisfactory. Working together as an industry, we have developed a superior approach to call setup with WNSRP."
Extensive testing of WNSRP has shown it to be backward compatible with currently marketed handsets, as required of a robust standard. The new standard was already implemented by many companies prior to its final approval and members of the consortium have independently tested their products.
RADVISION’s 3G-324M Toolkit, ProLab 3G, and SCOPIA 3G Video Gateway products support WNSRP. "RADVISION is dedicated to providing a superior user experience in multimedia systems," said Boaz Raviv, General Manager of RADVISION’s Technology and Networking Business Units. "By using RADVISION products, such as our 3G Gateway, developers can quickly implement WNSRP and gain significant competitive advantages for their real-time video services products."
Developers working on 3G-324M video telephony systems can test design interoperability through RADVISION's online 3G-324M IOT facility.
WNSRP Addresses a Technical Challenge
Call setup time was one of the last remaining challenges for real-time 3G video services. The "time outs" and retransmissions of the previous approach added to the already extensive setup time and introduced long delays that consumers were no longer willing to accept for video services. The WNSRP standard is based on a powerful new approach to call signaling that eliminates the message queuing and "time out" issues that are inherent with the 3G-324M standard. Missed messages are immediately detected and retransmissions are spontaneously generated leading to shorter call setup times and bringing video connectivity close to the same level of service as traditional telephony.
Looking beyond WNSRP to further improve call setup time, RADVISION has presented a complementary addition to WNSRP, which reduces call setup time to a single second. Known as ACN (Automatic Connect Negotiation), this proposed addition to the H.324 standard works seamlessly with WNSRP and uses the H.245 control channel to perform procedures in parallel during call setup. When combined, WNSRP and ACN result in the only standards-based fast call setup solution in the industry.
