subject: Cdma2000 Will Provide Carrier-class Voip For Fusion-cdma2000, Voip, Carrier-class - Communications [print this page] Los Angeles CT IAWirelessI.TLos Angeles CT IAWirelessI.T. & Entertainment Conference, September 12, 2006?? CDMA Development Organization (CDG) (www.cdg.org) today announced Cloth By upgrading to a dialogue Service Quality (QoS) of the 1xEV-DO version of the A network, CDMA2000 operators will take the lead in wireless 3G networks to provide carrier-grade IP voice Communicate Service. This upgrade not only support the use of VoIP Evolution Package All the latest real-time service and synchronization service, also supports network convergence, and reduce operating costs accordingly. It is noteworthy that, based on the quality of service (QoS) version of the A network will also improve the downlink and uplink data transfer rates, provide symmetry, and reduce high-priority delay-sensitive services, delay and interference. These services include: VoIP, to-talk (PTT), a key Multimedia (Push-to-media), video conferencing, multicasting, and a wealth of multiplayer 3D games.
"Able to Mobile Network to provide carrier-class VoIP service is the next few years will achieve a breakthrough in the biggest, "CDG executive director Perry LaForge said," VoIP is not only more flexible than circuit-switched networks, cost more low, but also help promote Telecommunications And entertainment, Consumption Electronic And information technology integration. "
Third Generation Partnership Project II (3G PP 2) has EV-DO version of the A were standardized. The technology has been enhanced to support delay-sensitive applications and the use of real-time applications fast call setup, short transmission time intervals, the length of the transmission of data packets through the rapid management of IP packet compression (RoHC), rapid mixing automatic repeat request (HARQ), incremental redundancy feedback in the uplink, fast and efficient link layer management information, quality of service (QoS), antenna diversity and mobile devices fast base station switching control (the handover). These closely related technological breakthroughs to make versions of A can be any type of mobile applications provide the best performance and lowest cost. Other wireless technology in the maturity and flexibility can match. A supported version of VoIP, will lead to circuit switched network and packet-based IP network the balance between the micro-change.
Lucent Technologies Network Solutions mobile access solutions business president MichaelIandolo, said: "By version A, operators can rapidly deploy voice, data, video and multimedia integration with applications based on VoIP to meet the world's great Most users of mobile communication needs. Lucent that version A is the transition to all IP key factor in cooperation with the CDMA community, we will be the first to make this a reality. "
"CDMA2000 version of A for the provision of IP-based voice, multimedia and broadband data services to create an unparalleled user experience provides a fast, convenient and transparent way." Motorola Senior Director of DarrenMcQueen said, "A realization of a carrier-class version of VoIP. Motorola introduced version of the A network synchronization service will bring new user experience, also allows for the rapid introduction of other CDMA operators to differentiate their services must first account for machines, feature-rich applications provide a platform. "
CDMA Nortel Vice President and General Manager DougWolff Table Said: "The success in CDMA20001xEV-DO based on the evolution of the A version will allow operators to use the spectrum currently used to continue delivering a variety of new, innovative, feature-rich IP applications. Version of the A's industry-leading performance support-talk and video telephony and other delay-sensitive conversational services, improve the quality of service operators. "
"VoIP as version A and the combination of increased voice capacity, so carriers can broadband technology for less than the cost of the current circuit-switched telephone call," Airvana CEO RandyBattat said, "It created a kind of Mobile broadband deployment to every corner Business Example, produced a lower cost to support new multimedia applications, increase revenue, promote the deployment, which will further reduce the cost of 'healthy Cycle '. "
EV-DO version of the A through VoIP carriers to provide access to the following benefits:
L network integration and interoperability?? No longer limited to a single access network, VoIP applications enable operators to EV-DO, wireline, cable, DSL and multiple access such as Wi-Fi network General Service.
L voice capacity?? Version of A through VoIP can offer a single 1.25MHz carrier within the support of 44 to 66 simultaneous voice calls, depending upon the support of performance and network load.
L development of applications and services faster?? The development of a new services or applications no longer need to spend years of time, the new IP-based EV-DO version of the A applications and services can be born a few weeks or months.
Costs?? VoIP-based mobile network easy to manage, more efficient than circuit-based mobile voice network operating costs lower.
[Key words]: CDMA2000 VoIP Carrier Comment Large In Small
