DISCUSIÓN

ActiveSetWeightingCoefficient : Active Set Weighting Coefficient (W) is used to weight either the measurement result of the best active set cell (M_best) or the sum of

measurement results of all active set cells (M_sum) when the UE calculates the reporting range for the events 1A (cell addition) and 1B (dropping of cell).

The formula is: W * M_sum + ( 1 - W )* M_best.

Def : 0

AdditionReportingInterval : When a monitored cell enters the reporting range and triggers event 1A (cell addition), the UE transmits a Measurement Report to the RNC. If the RNC is not able to add the monitored cell to the active set, the UE continues reporting after the initial report by reverting to periodical measurement reporting.

The parameter Addition Reporting Interval determines the interval between periodical measurement reports when such reporting is triggered by the event 1A.

Def : 2 --> 0.5 s

AdditionTime : When a monitored cell enters the reporting range (addition window), the cell must continuously stay within the reporting range for a given period of time before the UE can send a Measurement Report to the RNC in order to add the cell into the active set (event 1A).

The length of this period is controlled by the parameter Addition Time.

Rec : (11) 320 ms ==>RT, (11) 320 ms ==> NRT, (13) 1280 ms ==>HSDPA

AdditionWindow : Addition Window determines the relative threshold (A_Win) used by the UE to calculate the reporting range of event 1A. The threshold is either relative to the CPICH Ec/No measurement result of the best active set cell (M_best), or to the sum of active set measurement results (M_sum), depending on the value of the parameter Active Set

Weighting Coefficient (W).

When the CPICH Ec/No measurement result of a monitored cell (M_new) enters the reporting range, the UE transmits a Measurement Report to the RNC in order to add the monitored cell into the active set:

M_new >= W * M_sum + ( 1 - W )* M_best - A_Win

Rec : (8) 4dB ==> RT, (5) 2.5dB ==> NRT, (0) 0dB ==> HSDPA

DropTime : When an active set cell leaves the reporting range (drop window), the cell must continuously stay outside the reporting range for a given period of time before the UE can send a Measurement Report to the RNC in order to remove the cell from the active set (event 1B).

The length of this period is controlled by the parameter Drop Time.

Def : 640 ms (12)

DropWindow : Drop Window determines the relative threshold (D_Win) which is used by the UE to calculate the reporting range of event 1B. The threshold is either relative to the CPICH Ec/No measurement result of the best active set cell (M_best) or to the sum of active set measurement results (M_sum), depending on the value of the parameter Active Set Weighting Coefficient (W).

When the CPICH Ec/No measurement result of an active set cell (M_old) leaves the reporting range, the UE transmits a Measurement Report to the RNC in order to remove the cell from the active set:

M_old <= W * M_sum + ( 1 - W )* M_best - D_Win

Def : (12) 6dB ==> RT, (8) 4dB ==> NRT, (8) 4dB ==> HSDPA

EcNoFilterCoefficient : In the CELL_DCH state the UE physical layer measurement period for intra-frequency CPICH Ec/No measurements is 200 ms. The Filter Coefficient parameter controls the higher layer filtering of physical layer CPICH Ec/No measurements before the event evaluation and measurement reporting is performed by the UE.

Def : 3 (600 ms)

HHoEcNoCancel : If the inter-frequency or inter-RAT (GSM) handover caused by low measured absolute CPICH Ec/No is enabled, the RNC starts the inter-frequency or GSM measurement in compressed mode when all active set cells have triggered the reporting event 1F for CPICH Ec/No.

The RNC cancels the event 1F of an active set cell if the CPICH Ec/No measurement result of the active set cell becomes better than or equal to the threshold HHoEcNoCancel and the UE transmits the corresponding event 1E triggered Measurement Report to the RNC.

Note that once the RNC has started the inter-frequency or inter-RAT (GSM) measurement for the purpose of hard handover due to low measured absolute CPICH Ec/No, the RNC does not break off the ongoing measurement, even if one or more active set cells trigger the

reporting event 1E for CPICH Ec/No.

Rec : -11dB ==> RT, -12dB ==> NRT, -15dB ==> HSDPA

MaxActiveSetSize : This parameter determines the maximum number of cells which can participate in a soft/softer handover.

Reporting deactivation threshold indicates the maximum number of cells allowed in the active set in order for the event 1A to trigger. The RNC calculates the deactivation threshold from the parameter MaxActiveSetSize: Reporting Deactivation Threshold = MaxActiveSetSize - 1

Reporting Deactivation Threshold parameter is part of System Information Block 11/12.

Replacement activation threshold information element indicates the minimum number of cells allowed in the active set in order for the event 1C to trigger. The threshold equals to the maximum size of the active set which is controlled with the parameter

MaxActiveSetSize.

Replacement Activation Threshold parameter is part of System Information Block 11/12.

Def : 3

HHoEcNoCancelTime : If the inter-frequency or inter-RAT (GSM) handover caused by low measured absolute CPICH Ec/No is enabled, the RNC starts the inter-frequency or GSM measurement in compressed mode when all active set cells have triggered the reporting event 1F for CPICH Ec/No.

The RNC cancels the event 1F of an active set cell if the CPICH Ec/No measurement result of the active set cell becomes better than or equal to the threshold HHoEcNoCancel and the UE transmits the corresponding event 1E triggered Measurement Report to the RNC.

The parameter HHoEcNoCancelTime determines the time period during which the CPICH Ec/No of the active set cell must stay better than the threshold HHoEcNoCancel before the UE can trigger the reporting event 1E.

Note that once the RNC has started the inter-frequency or inter-RAT (GSM) measurement for the purpose of hard handover due to low measured absolute CPICH Ec/No, the RNC does not break off the ongoing measurement, even if one or more active set cells trigger the

reporting event 1E for CPICH Ec/No.

ReplacementReportingInterval: When the number of cells in the active set has reached the maximum, and a monitored cell becomes better than an active set cell, the UE transmits a Measurement Report to the RNC in order to replace the active cell with the monitored cell (event 1C).

If the RNC is not able to replace the active cell with the monitored cell, the UE continues reporting after the initial report by reverting to periodical measurement reporting. The parameter Replacement Reporting Interval determines the interval of periodical

measurement reports when such reporting is triggered by the event 1C.

Def : 2 (0.5s)

HHoEcNoThreshold : If the inter-frequency or inter-RAT (GSM) handover caused by low measured absolute CPICH Ec/No is enabled, the UE transmits an event 1F triggered

measurement report to the RNC when the CPICH Ec/No measurement result of an active set cell becomes worse than or equal to an absolute CPICH Ec/No threshold.

The parameter HHoEcNoThreshold determines the absolute CPICH Ec/No threshold which is used by the UE to trigger the reporting event 1F. When the measured CPICH Ec/No of all active set cells has become worse than or equal to the threshold in question, the RNC starts inter-frequency or inter-RAT (GSM) measurements in compressed mode for the purpose of hard handover.

Rec : -14dB ==> RT, -15dB ==> NRT, -18dB ==> HSDPA

ReplacementTime : When the number of cells in the active set has reached the maximum, and a monitored cell enters the reporting range (replacement window), the monitored cell must continuously stay within the reporting range for a given period of time before the UE can send a Measurement Report to the RNC in order to replace an active set cell with the monitored cell (event 1C). The length of this period is controlled by the parameter

Replacement Time.

HHoEcNoTimeHysteresis : If the inter-frequency or inter-RAT (GSM) handover caused by low measured absolute CPICH Ec/No is enabled, the UE transmits an event 1F triggered

measurement report to the RNC when the CPICH Ec/No measurement result of an active set cell becomes worse than the threshold HHoEcNoThreshold.

The parameter HHoEcNoTimeHysteresis determines the time period during which the CPICH Ec/No of the active set cell must stay worse than the threshold HHoEcNoThreshold before the UE can trigger the reporting event 1F. When the measured CPICH Ec/No of all active set cells has become worse than the threshold in question, the RNC starts inter-frequency or inter-RAT (GSM) measurements in compressed mode for the purpose of hard handover.

maximum specified by the parameter MaxActiveSetSize and a monitored cell becomes better than an active set cell, the UE transmits a Measurement Report to the RNC in order to

replace the active cell with the monitored cell (event 1C). The parameter Replacement Window determines the margin by which the CPICH Ec/No measurement result of the monitored cell (MNew) must exceed the CPICH Ec/No measurement result of the an active set cell (MInAS) before the UE can send the event 1C triggered Measurement Report to the RNC:

MNew >= MInAs + ReplacementWindow / 2 Def : 4 (2dB)

HHoRscpCancel : If the inter-frequency or inter-RAT (GSM) handover caused by low measured absolute CPICH RSCP is enabled, the RNC starts the inter-frequency or GSM measurement in compressed mode when all active set cells have triggered the reporting event 1F for CPICH RSCP. The RNC cancels the event 1F of an active set cell, if the CPICH RSCP measurement result of the active set cell becomes better than or equal to the threshold HHoRscpCancel and the UE transmits the corresponding event 1E triggered measurement report to the RNC.

Note, that once the RNC has started the inter-frequency or inter-RAT (GSM) measurement for the purpose of hard handover due to low measured absolute CPICH RSCP, the RNC does not break off the ongoing measurement, even if one or more active set cells trigger the reporting event 1E for CPICH RSCP.
