The performance of kind system for uplink packet data.Therefore, high-speed uplink packet access technology introduce a kind of new transmission channel-
Enhanced dedicated (E-DCH, Enhanced Dedicated Transport Channel) is used to carry number of users
According to E-DCH is dedicated for the up channel of carrying upstream data.In addition, the physics letter of bearing reinforced dedicated transmission channel
Road is Physical Random Access Channel (PRACH, Physical Random Access Channel).
Terminal has two basic manipulation modes, is idle mode and connected mode respectively.Connection mode can further divide
For following different state：Universal Mobile Telecommunications System wireless access network registration area PCH (utran registration area_paging indicator channel, Universal
mobile telecommunication system Radio access network Register area Paging
Channel) state, cell paging channel (CELL_PCH, CELL Paging Channel) state, cell forward access channel
(CELL_FACH, CELL Forward Access Channel) state and cell private channel (CELL_DCH, CELL
Dedicated Channel) state etc., these states define the kind of the physical channel that terminal can use and transmission channel
Class.
In the cell -- fach state, high-speed uplink packet access technology can be used when sending upstream data in terminal,
Uplink user data is sent by enhanced dedicated.The Transmission Time Interval of enhanced dedicated has two
Kind, a kind of is 2 milliseconds of Transmission Time Interval, that is, carries out enhanced dedicated with 2 milliseconds of gap periods
