Mobile IPv6 in CDMA Packet Data Networks
It’s important to remember that the relationship between different media tends to be complementary. When new media arrive they don’t necessarily replace or eradicate previous types. Though we should perhaps observe a half second silence for the eight-track. There that’s done. What usually happens is that older media have to shuffle about a bit to make space for the new one and its particular advantages. Radio did not kill books and television did not kill radio or movies - what television did kill was cinema newsreel. TV does it much better because it can deliver it instantly.

The CDMA cellular networking system is one of the most widely deployed mobile networking technologies in use today. This system has a specific architecture for supporting packet data services beginning with the so-called 1XRTT systems. In this model, a Mobile Station (MS) connects to a Packet Data Serving Node PDSN through the wireless base station, obtains an IP address and engages in packet data communication. In the following, we review the elements of this architecture and the procedures for establishing IP connectivity. We subsequently discuss how IP mobility is supported.
Before jumping into the functional description of the CDMA packet data architecture, we need to define some terms. Figure ...
