re: AWS & Nokia - EDGE / UMTS / IP-based Network / VoIP Using SIP / AMR / QoS
>> UMTS To Come to America
UK Cellular News
June 5 2001
Nokia and AT&T Wireless have announced that they are to extend their 3G development to include UMTS for the American market. The companies, currently working on Enhanced Data Rates for Global Evolution (EDGE), will now begin to start testing UMTS and the protocols that will enable voice, data and video services to run on a IP-based network.
In the past year, the two companies have completed several milestones in the trial project, including Voice over IP (VoIP) using Session Initiated Protocol (SIP) call control, Adaptive Multi-Rate speech codec (AMR), streaming audio and video, and simultaneous voice and data calls with Quality of Service (QoS) scheduling and handover. The current cooperation agreement builds upon these milestones to begin validation of key technologies of the Nokia All-IP solution: IPv6, UMTS, and IP-based Service Architecture.
The companies say that they will base their validation efforts on releases R4 and R5 of the 3GPP International Standards for EDGE and UMTS radio-interface technology. AT&T Wireless will begin adding EDGE & UMTS in the 2002-2003 timeframe. <<
