D efinition
wnlink threshold for channel switching from common to dedicated substate for single RAB. ( Common -> dedicated)nk threshold for channel switching from common to dedicated substate. ( Common -> dedicated)shold for channel switching from dedicated to common substate. ( Dedicated -> Common)er threshold to achieve hysteresis for channel switching from dedicated to common substate. ( Dedicated -> Common)e during which throughput has to be low in order to trigger a downswitch (dedicated to common substate) for a UE in state DCH/DCH.e during which throughput has to be low in order to trigger a downswitch (dedicated to common substate) for a UE in state DCH/HS or in stank throughput threshold required for triggering an upswitch of the uplink, expressed as a percentage of the maximum channel capacity.e during which the uplink throughput must be higher than that specified by bandwidthMarginUl before an upswitch request is issued.e during which the downlink throughput must be lower than that specified by dlDownswitchBandwidthMargin before an downswitch request is

wnlink throughput threshold required for triggering an upswitch of the downlink, expressed as a percentage of the maximum channel capacitye during which the uplink throughput must be lower than that specified by ulDownswitchBandwidthMargin before an downswitch request is isnk throughput threshold required for triggering a downswitch of the uplink, expressed as a percentage of the maximum channel capacity of nnk throughput threshold which the throughput must have been below in order to allow an upswitch. If set to 0, this parameter is not in use.e during which the power is allowed to be high before a downswitch (DCH to DCH) is issuedgin, in relation to maximum allowed code power, which indicates a high power usage.e, without data transmission, after which a UE in state CELL_FACH is switched down to state URA_PCH. If URA_PCH state is not available thewitch (DCH to DCH) power marginer for sending of IU RELEASE REQUEST message to CN for UE in state URA_PCHe during which the downlink throughput must be higher than that specified by bandwidthMargin before an upswitch request is issued.
