9.2.4 Continuous Packet Connectivity
As packet data services expand, users will want to experience continuous connectivity. 3GPP has coined
a term called Continuous Packet Connectivity (CPC) where users are essentially always connected with
an occasional transmission. This technique removes the delays involved in connection establishment.
For large number of High Speed Downlink Packet Access (HSDPA) users having the associated
dedicated physical data channel (DPDCH) and DPCCH, each user can quickly approach a codelimited
scenario. Hence is one of the reasons F-DPCH is included in the Release 6 version. For this case
the UE will monitor traffic on the HS-DSCH channel and uplink PC commands on the F-DPCH channel.
