Agilent Monitors and Manages Wireless SIP-based Push-to-talk Services

9/25/2003 - Agilent Technologies Inc. (NYSE: A) announced the industry's first operations support system (OSS) to manage wireless SIP-based push-to-talk (PTT) services. Agilent OSS NgN Analysis System enables voice-over-IP (VoIP) service providers to monitor, troubleshoot and identify call quality and failure issues for reduced customer turnover, lower operational cost and faster resolution of network problems.

Push-to-talk enables wireless users to connect in a "walkie-talkie" mode with other individuals or with groups of mobile phone users at the push of a button. The session initiation protocol (SIP) is used to establish and maintain the connection between PTT-enabled handsets. Consumers are increasingly interested in PTT. The technology research firm Zelos Group found in an August 2003 survey of 1,300 wireless consumers that 45 percent indicated an interest in having PTT capabilities on their next wireless handset.

"Wireless service providers face many challenges in the rapid deployment of the complex push-to-talk application," said Bill Mortimer, vice president and general manager of new generation networks and services, Agilent OSS business unit. "PTT services must be monitored and managed effectively to maintain reliable IP connectivity and high-quality voice service. Today, Agilent is the only OSS supplier supporting the complex network and service management needs of SIP push-to-talk."

NgN Analysis System ensures PTT service quality by collecting and analyzing all call transactions transmitted over the network. The product offers unique, network-wide troubleshooting and service-level management capabilities by correlating all SIP signaling into individual call records and call-performance metrics. This enables network operators to manage the service level of individual calls more effectively by analyzing and troubleshooting VoIP signaling and quality issues.

Leading packet protocols supported by NgN Analysis System include SIP, MGCP, H.323, NCS, TGCP, IPDC, SS7 and RADIUS, as well as leading proprietary protocols such as Q.931/RUDP.
