Home Agent

The Home Agent (HA) is the third major component to the CDMA2000
packet data service network and should be compliant with IS-835, which is
relevant to the HA functionality within a wireless network. The HA performs
many tasks, some of which are tracking the location of the mobile IP
subscriber as it moves from one packet zone to another. In tracking the
mobile, the HA will ensure that the packets are forwarded the mobile itself.
