A Mobile Station accesses the CDMA2000 network through the The CDMA2000 network comprises of the Radio Access Network (RAN) and the Core Network. Protocol) session is created between the Mobile Station and the Packet Data Serving Node (PDSN). For each data session, a PPP (Point-to-Point PSD offers higher data rate for multimedia services. Rate of 19.2 kbps and is delivered over traditional TDM circuits. ![]() An IS-2000 compliant Mobile Station (MS) can select either packet-switched data (PSD) or circuit-switched data (CSD) transport. IS-2000 is the signaling standard, which defines protocols for several critical 3G CDMA interfaces pertaining to packet transmission namely A1, A7, A9 and A11 The latest 3G technology, called CDMA 2000 1圎V-DV is capable of delivering integrated voice and simultaneous multimedia services at peak data rates With respect to old 2G or 2.5G networks (GSM and GPRS network). In order to deliver both voice as well as data service with very high transmission rate, CDMA network has incorporated many new nodes and protocols ![]() CDMA technology has undergone many stages of revolution to offer improved voice and data service to the end users. ![]()
