{"Image DocumentName": "Evolution of UMTS Technical Specifications to Release 5 (Rel\u20195) of the 3GPP \u2013 Transition to IMS", "Image ImageDescription": "Release 1999 (R\u201999) in April the initial standards for UMTS were. completed by 3GPP. These standards are the basis for a majority of the. current commercially deployed UMTS systems. Release 4 (Rel\u20194) in April 2001 was standardized in 3GPP, which provided. some improvements of the UMTS transport, radio interface and architecture. Rel\u20195 of UMTS was completed in March next significant evolution phase. of UMTS. UMTS Rel\u20195 will provide higher speed wireless data services with. vastly improved spectral efficiencies through the High Speed Downlink Packet.
