The allocations can be either permanent needing a DCH release message or based on time or amount-of-data. Resource allocation can be done separately for each packet burst with fast signalling on the DCH. Transition out of the Control only state is either triggered by user capacity allocation or by timeout no data transaction requests received within a specified time period. For each radio frame the UE and the network indicate the current data rate in uplink and downlink respectively using the transport format combination indicator TFCI.
If the configured set of combinations i. This reconfiguration can be done during or in between data transmission. Further, the network can reconfigure the physical channel allowing an increase or decrease of the peak data rate. For the uplink data transmission, the UE reports the observed traffic volume to the network in order for the network to re-evaluate the current allocation of resources.
This report contains e. If during data transfer the UE is unable to transmit at the requested output power when using the peak allocated capacity, the UE shall reduce transmission rate within the current 10 ms radio frame in order to maintain the closed-loop power control.
The RRC Connection mobility is handled by measurement reporting, soft handover and hard handover procedures. 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. Examples of these procedures are given in section Error! Reference source not found..
It is enabled to transmit uplink control signals and it may be able to transmit small data packets on the RACH. The network can assign the UE stransport channel parameters e.
The UE shall use the common physical channel and transport channel configuration according to the system information when no UE dedicated common physical channel or transport channel channel configuration has been assigned. When there is either user or control data to transmit, a selection procedure determines whether the data should be transmitted on a common transport channel, or if a dedicated transport channel should be allocated.
The selection should be dynamic and depend on traffic parameters amount of data, packet burst frequency. In this substate measurement reporting and hard handover procedures can be used. Downlink data transmission on the FACH can be started without prior paging. The UE monitors the broadcast channel and system information on BCCH of its own and neighbour cells and from this the need for the updating of cell location is identified. Upon selecting a new cell belonging to another radio access system than UTRA, the UE shall enter idle mode and make an access to that system according to its specifications.
The UE shall use the measurement control information according to the system information when no UE dedicated measurement control information has been assigned. The scheduling on the broadcast channel is done in such way that the UE knows when the requested information can be found.
When the system information is modified, the scheduling information is updated to reflect the changes in system information transmitted on BCH. The DCCH logical channel cannot be used in this substate. If the network wants to initiate any activity, it needs to make a paging request on the PCCH logical channel in the known cell to initiate any downlink activity. This can be controlled with an inactivity timer, and optionally, with a counter, which counts the number of cell updates.
For this purpose, a transition to another substate has to be executed. In this state, the UE mobility is performed through URA reselection procedures, which may differ from the definitions in S2. Upon selecting a new cell belonging to another radio access system than UTRA, the UE shall enter idle mode and make an access to that system according to its specifications FFS.
In case of Inter-system handover failure the UE has the possibility to go back to UTRAN Connected Mode and re- establish the connection in the state it originated from without attempting to establish a temporary block flow. In case of Inter-system handover failure the UE has the possibility to go back to GSM Connected Mode and re-establish the connection in the state it originated from.
