Description

Value range: 0~65535

Physical unit: None

Content: Uniquely identifying a cell

Recommended value: None

Value range: CPICH_ECNO(CPICH Ec/N0), CPICH_RSCP(CPICH RSCP)

Physical unit: None

Content: Measurement quantity of cell selection and reselection. It can be set to CPICH Ec/N0 or CPICH RSCP.

For detailed information of this parameter, refer to 3GPP TS 25.304.

Recommended value: CPICH_ECNO

Value range: 0~20

Physical value range: 0~40; step: 2

Physical unit: dB

Content: The hysteresis value of the serving FDD cells in idle mode in case the quality measurement for cellselection and reselection is set to CPICH RSCP. It is related to the slow fading feature of the area where the cell is

located. The greater the slow fading variance is, the greater this parameter.

According to the R regulation, the current serving cell involves in cell selection after the measurement value is

added with the hysteresis value. The measurement hysteresis aims to prevent the ping-pong effect of the cell

reselection, which is caused by the slow fading when the UE is on the edge of the cell. The ping-pong effect may

trigger frequent location updates (idle mode), URA updates (URA_PCH), or cell updates (CELL_FACH, CELL_PCH),

and thus increase the load of network signaling and the consumption of UE batteries. Set a proper measurement

hysteresis to reduce as much as possible effect of the slow fading as well as ensuring timely cell updates of the

UE. According to the CPICH RSCP emulation report of inter-frequency hard handovers, the measurement

hysteresis ranges 4 dBm to 5 dBm and is set to 4 dBm by default when the slow fading variance is 8 dB and the

relative distance is 20 m. In the cells where the slow fading variance is low and the average moving speed of UEs

is high, for example the suburbs and countryside, reduce the measurement hysteresis to guarantee timely

location updates of UEs. The higher the measurement hysteresis is, the less likely it is for various types of cell

reselections to occur, and the better the slow fading resistance capability is, but the slower the system reacts to

the environment changes. For detailed information of this parameter, refer to 3GPP TS 25.304.

Value range: 0~20


Physical unit: dB.


23/201

Recommended value:the same as Qhyst1s for connect mode.

Value range: 0~31

Physical unit: s

Content: If the signal quality (CPICH Ec/No measured by the UE) of a neighboring cell is better than that of the

serving cell during the specified time of this parameter, the UE reselects the neighboring cell. It is used to avoid

ping-pong reselection between different cells. Note that the value 0 corresponds to the default value defined in

the protocol.

Set the parameter as follows:

1. Ensure that the UE can reselect a cell when crossing the non-soft-switch area of the cell and that the UE timely

performs location updates, cell updates, or URA updates when necessary.

2. Ensure that the UE does not reselect a cell when it is in the soft-switch area of the cell. In this way, the

unnecessary location updates, cell updates, and URA updates are avoided.

3. Consider the difference between cells that cover different areas, for example the cells covering highways and

cells covering densely populated areas. TIf the parameter is set to a comparatively low value, the ping-pong

reselections may be caused. The parameter can be increased in populated area and reduced in high-speedmovement. If the parameter is set to a comparatively high value, the cell reselection delay may become

excessively high, and thus cell reselections may be affected.

For detailed information, refer to 3GPP TS 25.304.


Value range: -24~0

Physical unit: dB

Content: The minimum required quality threshold corresponding to CPICH Ec/No. The UE can camp on the cell

only when the measured CPICH Ec/No is greater than the value of this parameter. The higher the parameter

value is, the more difficult it is for the UE to reside in the cell. The lower parameter value is, the easier it is for

the UE to reside in the cell, but it is possible that the UE cannot receive the system messages that are sent

through the PCCPCH. For detailed information, refer to the 3GPP TS 25.304.

Recommended value: -18

Physical value range: -115~-25; step: 2 (-58:-115; -57:-113; ...; -13:-25 )

Physical unit: dBm


25/201

Content: The minimum required RX threshold corresponding to CPICH RSCP. The UE can camp on the cell only

when the measured CPICH RSCP is greater than the value of this parameter. The setting of Qrxlevmin should be

related to Qqualmin. The higher the parameter is, the more difficult it is for the UE to reside in the cell. The

lower parameter is, the easier it is for the UE to reside in the cell, but it is possible that the UE cannot receive the

system messages that are sent through the PCCPCH. For detailed information, refer to 3GPP TS 25.304.

Content: Threshold for intra-frequency cell reselection in idle mode. When the quality (CPICH Ec/No measured

by the UE) of the serving cell is lower than this threshold plus the [Qqualmin] of the cell, the intra-frequency cell

reselection procedure will be started. This parameter is not configured when its value is 127. The intra-frequency

cell reselection has a priority higher than the inter-frequency cell reselection and inter-RAT cell reselection, theintra-frequency cell reselection start threshold should be higher than the inter-frequency cell reselection start

threshold and inter-RAT cell reselection start threshold. If the cell reselection threshold is set to a comparatively

high value, the UE may frequently start cell reselections, and the battery of the UE may be largely consumed. If

the cell reselection threshold is set to a comparatively low value, it is difficult for cell reselections to be started,

and the UE may not timely reside in the cells with good quality, affecting the quality of communication between

the UTRAN and the UE. For detailed information, refer to 3GPP TS 25.304.

Description:Only when the measured background noise's duration reaches this parameter, the output of the

auto-adaptive background noise update filter could be regarded as effect background noise, and the current

Description:Reserved DL power factor for HSUPA user. The higher the value is, the more resources reserved for

the HSUPA control channel, which leads to resource waste. If the value is too low, HSUPA user quality may beGUI value range:0~100

Description:Available guarantee power of all the MTCHs. This parameter is a protection for the MBMS PTM

bearing. When the power of all the MTCHs are little, pre-emption of MBMS PTM bearing should be avoided. This

is because the MBMS PTM bearing serves multiple users at the same time. The value should not be too high.

Description:Available guarantee codes of all the MTCHs. This parameter is a protection for the MBMS PTM

bearing. When the codes of all the MTCHs are few, pre-emption of MBMS PTM bearing should be avoided. This

is because the MBMS PTM bearing serves multiple users at the same time. The value should not be too high.

Description:Uplink Credit Reserved by Spread Factor for HandOver. SFOFF means that none of them are reserved

for handover. If the UL spare resource cant satisfy the reserved resource after the access of a new service, the

service will be rejected. If the value is too high, the credit resource reserved for handover UEs will be less,

leading to the increased possibility of rejecting handover UE admissions, and performance of handover UEsGUI value range:SF4(SF4), SF8(SF8), SF16(SF16), SF32(SF32), SF64(SF64), SF128(SF128), SF256(SF256),

Description:Some cell resources can be reserved for handover UEs to guarantee handover success rate and

improve access priority of handover services. This parameter defines the quantity of downlink code and CE

resources reserved for handover. SFOFF refers to that no resources is reserved. SF32 refers to that a code

resource with SF = 32 and its corresponding credit resource are reserved. The backer position the value is in

{SF4,SF8,SF16,SF32,SF64,SF128,SF256,SFOFF}, the less code and credit resources reserved for handover UEs. The
