*Which physical channels that are allocated to the UE, and thus which transport channels that can be used
*Which type of RRC connection mobility procedures that are used.
*The level of UE activity, e.g. whether it is known on cell or URA level and whether or not it uses DRX.
We also propose to remove transient states as long as they can be hidden into the specification of the procedures.
##RRC status:
A short specification of each RRC state in connected mode is given below:
1- CELL_DCH
The CELL_DCH state is characterised by:
-A dedicated physical channel is allocated to the UE in uplink and downlink.
-The UE is known on cell level according to its current active set.
In this state, the UE shall
*Use the connected mode measurement control information received in other states until new measurement control information has been assigned to the UE
* perform measurements and transmit measurement reports according to the measurement control information
*depending on UE capabilities, monitor the FACH to receive any broadcast messages
*monitor a DSCH in downlink for user data and signalling messages when instructed by UTRAN
2- CELL_FACH
The CELL_FACH state is characterized by:
*Neither an uplink nor a downlink dedicated physical channel is allocated to the UE.
*The UE the continuously monitors a FACH in the downlink
*The UE is assigned a default common or shared transport channel in the uplink (e.g. RACH) that it can use anytime according to the access procedure for that transport channel
*The UE is known on cell level according to the cell where the UE last made a cell update.
In this state, the UE shall :
- Use C-RNTI assigned in the current cell as the UE identity on common transport channels unless when a new cell is selected
- monitor a FACH to receive signalling messages or user data addressed to the UE or any broadcast messages
- acquire system information on the BCH and use the common physical channel and transport channel configuration and measurement control information according to that system information when no UE dedicated common physical channel and transport channel configuration and measurement control information has been assigned to the UE
by default, use RACH for transfer of signalling messages or user data in the uplink according to the random access procedure
- use transport channels of type CPCH or USCH (TDD only) for transfer of signalling messages or user data in the uplink accordong to the access procedures when instructed by the UTRAN
- perform cell reselection and upon selecting a new UTRA cell, initiate a cell update procedure
- upon selecting a new cell belonging to another radio access system than UTRA, enter idle mode and make an access to that system according to its specifications
- perform measurements and transmit measurement reports according to the measurement control information

3- CELL_PCH
The CELL_PCH state is characterised by:
-Neither an uplink nor a downlink dedicated physical channel is allocated to the UE
-The UE uses DRX for monitoring a PCH via an allocated PICH.
-No uplink activity is possible [note: if the UE wants to make an uplink access it autonomously shall enter the [CELL_FACH state].
- The UE is known on cell level according to the cell where the UE last made a cell update in CELL_FACH state.
In this state, the UE shall
*monitor the paging occasions according to the DRX cycle and receive paging information on the PCH
*acquire system information on the BCH and use the measurement control information according to that system information when no dedicated measurement control information has been assigned to the UE
*perform cell reselection and upon selecting a new UTRA cell, enter the CELL_FACH state and initiate a cell update procedure
*upon selecting a new cell belonging to another radio access system than UTRA, enter idle mode and make an access to that system according to its specifications
*perform measurements according to the measurement control information
* when needed according to the measurement control information, enter CELL_FACH state and transmit measurement reports
4- URA_PCH
The URA_PCH state is characterised by:
-Neither an uplink nor a downlink dedicated physical channel is allocated to the UE
-The UE uses DRX for monitoring a PCH via an allocated PICH.
-No uplink activity is possible [note: if the UE wants to make an uplink access it autonomously enters the[CELL_FACH state].
-The UE is known on URA level according to the URA assigned to the UE during the last URA update inCELL_FACH state.
In this state, the UE shall
* monitor the paging occasions according to the DRX cycle and receive paging information on the PCH
* acquire system information on the BCH and use the measurement control information according to that system information when no dedicated measurement control information has been assigned to the UE
* perform cell reselection and upon selecting a new UTRA cell that does not match the URA assigned to the UE,
enter the CELL_FACH state and initiate a URA update procedure
*upon selecting a new cell belonging to another radioaccess system than UTRA, enter idle mode and make an access
to that system according to its specifications (FFS)
*perform measurements according to the measurement control information
*when needed according to the measurement control information, enter CELL_FACH state and transmit measurement reports
