Provision of stable and reliable radio connections for the upper-level services
through soft/hard handoff
The PCF manages the Radio-Packet (R-P) connection. As radio resources are limited,
they should be released when subscribers are not sending or receiving any information.
But the Peer-Peer Protocol (PPP) connection must be maintained. The PCF shields the
radio mobility from the upper-level services through the handoff function.
III. MS/AT
l
MS
MS is the equipment used by the mobile subscriber. It can originate and receive
calls, and communicate with the BSS.
l
AT
AT is a device with a radio modem and a data interface that allows the user to
access a packet data network through the 1xEV-DO Access Network.
An AT is analogous to a mobile station in an CDMA2000 1x system. It may be
connected to a computing device like a laptop computer or may be a
self-contained data device like a Personal Digital Assistant (PDA).
