Impact on Radio Network Performance Introduced in Version

When this switch is set to 0, RLC entities must be re-

established in both uplink and downlink during F2D,

causing the UE rate to slowly increase and slightly reducingthe throughput. When this switch is set to 1, RLC entities

can be re-established in only the uplink or downlink during

F2D. In this case, the UE rate increases properly.

When this switch is turned on, SRBs cannot be switched

over from DCHs to HSPA channels during directed retry.

V900R012C01SPC200

V900R013

Turning on this switch prevents inconsistency in uplink and

downlink AMR mode configurations. This solves the

compatibility issues of some UEs.


V900R011C00SPC700

V900R012

V900R013

When this switch is turned on, the RNC determines whether

the uplink coverage of a UE is insufficient during BE serviceestablishment based on the Ec/No reported by the UE in

the RRC connection establishment phase. If the reported

Ec/No is lower than the Ec/No decision threshold, the

uplink coverage of the UE is insufficient. In this case, the

RNC establishes the BE service on R99 channels instead of

on HSUPA channels. The Ec/No decision threshold specifies

whether to services should be switched over from E-DCHs to

DCHs. This prevents call drops when HSUPA signals are

weaker than R99 signals.

V900R012C01SPC506

V900R013

This switch is added to enable the optimized downlink-load-

based directed retry algorithm. The optimized algorithm is

used to solve the following problem: When HSPA+ UEs

access cells not supporting HSPA+, these HSPA+ UEs

cannot use HSPA+ features or DC-HSDPA or uplink load

balancing does not take effect for DC-HSDPA.

If this switch is turned on and the cell HSUPA function is

enabled, BE services can be switched over from E-DCHs to

DCHs due to weak coverage. This reduces the service drop

rate.

V900R012C01SPC506

V900R013

When this switch is turned on, the D2F procedure is

triggered regardless of the existence of the CCCH over the

Iur interface. If the D2F procedure fails, directed signaling

connection re-establishment (DSCR) is triggered to prevent

congestion of UEs in the CELL_DCH state under the RNC.

For UEs that obtain the transmission block size (TbSize)

based on the 0 kbit/s transport format (TbNum * TbSize):

When this parameter is set to 0, the transmission block size

is 0 and the AMR speech service fails. When this parameter

is set to 1, the transmission block size is TbSize and the

AMR speech service is normal.

V900R011C00SPH726

V900R012C01SPC500

V900R013

When this switch is turned on, multiple cross-Iur RLs

belonging to the same DRNC can be added simultaneously.

If an RL fails to be added with the failure cause of

RadioNetwork:unspecified (14), the RNC attempts to re-

establish the RL only once.

V900R012C01SPC506

V900R013

When the switch is turned on, the uplink PS service must be

carried on DCHs if CS and PS services co-exist. Establishing

PS services on DCHs reduces the number of physical

channel reconfigurations and RB reconfigurations triggered

by various reasons. This reduces the call drop rate of CS

services in combined CS and PS services.

V900R012C01SPC506

V900R013

Due to a compatibility issue, some UEs fail to move from

the CELL_FACH to CELL_DCH state, which causes the UEs to

remain in the CELL_FACH state. The UEs in the CELL_FACH

state, however, transmit data at low rates. This affects the

user experience.

When CORRM_RESERVED_SWITCH_1_BIT6 is set to 1,

setting RESERVED_SWITCH_0_BIT2 and

RESERVED_SWITCH_0_BIT14 to 1 saves system resources.

This also prevents KPIs from deteriorating due to a

decrease in system capacity and reduces the risks of CS

service admission rejections. The call drop rate of

combined CS and PS services may increase because an RB

reconfiguration is required for transmitting heartbeat

packets or other PS services.

V900R012C01SPH518V900R013C00SPC520

When this switch is turned on, downlink PS services must

be carried on DCHs if a UE that complies with 3GPP

Release 6 or later runs combined CS and PS services.

Establishing PS services on DCHs reduces the number of

physical channel reconfigurations and RB reconfigurations

triggered by various causes. This reduces the call drop rateof CS services in combined CS and PS services.

V900R012C01SPH512

V900R013C00SPC500

When this switch is turned on, the RNC releases all

resources for a UE if the following conditions are met:

The UE performs a CELL_DCH-to-CELL_FACH state

transition.

The FACH is congested.

The UE is processing a non-real-time PS service that has a

traffic volume of 0 bytes. This increases the number of RRC

connection setups and RAB setups.

V900R012C01SPH516

V900R012C01SPH224

V900R013C00SPC510

When this switch is turned on, directed retry and channel

fallback are allowed after a P2D procedure fails. This

increases the P2D success rate.

V900R012C01SPH516

V900R013

When this switch is turned on, if the Iur CCH switch isturned off during a cross-Iur soft handover and the PTT

service meets the D2F trigger conditions, then:

A DSCR procedure may be triggered if the best cell is a

DRNC cell.

A D2F procedure may be performed if the best cell is an

SRNC cell.

When this switch is turned off, the original processing

procedure is performed.

Turning on this switch prevents UEs running PTT services

from staying in the CELL_DCH state after their PTT services

are terminated because CELL_DCH-to-CELL_FACH-to-

CELL_PCH (D2F2P for short) procedures fail to be

performed. This reduces UE power consumption and saves

network resources.

V900R012C01SPH516

V900R013C00SPC500

When this switch is turned on, the RNC performs a low-

activity rate algorithm on a UE that uses DCHs in only the

uplink or downlink. The low-activity rate algorithm saves

cell resources in the direction where it applies, but may

reduce the transmission rate in the reverse direction.

If the active set of a UE has too many cells, the

measurement reports sent by the UE are large, which may

lead to SRB reset.

When this switch is turned on, the intra-frequency

ReadSFNInd in system information SIB11/SIB12 of a cell is

set to the fixed value READ. This prevents call drops of

some UEs during soft handovers and thereby increases the

success rate of soft handovers.

V900R012C01SPH516

V900R013C00SPC510

When this switch is turned off, the GTPU is not reconfigured

if a UE in the CELL_PCH state performs a cell update with a

cause value of cell reselection, periodical cell update, or re-

entered service area. This prevents a significant increase in

the GOUa CPU usage after the CELL_PCH function is

enabled.

V900R013C00SPC510

When this switch is turned off, service setup may fail or call

drops may occur if the difference between the actual Iub

transmission delay and the configured value is large.

Turning on this switch solves the problem that SPU

subsystems in newly added RNC subracks cannot obtain

the Iub transmission delay of NodeBs configured on the

SPU subsystems in existing RNC subracks. This problem

occurs because the SPU subsystems in original subracks do

not broadcast Iub transmission delay.

Turning on this switch increases the setup success rate of

high-priority services because preemption is allowed but

also increases CPU load.

V900R012C01SPH522

V900R013C00SPH526

When this switch is turned off, UEs cannot parse messages

on the PCH or FACH due to a change in the channelization

code used by a common channel. This reduces the setup

success rate of RRC connections.

Turning on this switch resolves this problem.

V900R012C01SPH522

V900R013C00SPC550

When this switch is turned on and the algorithm of

differentiated fairness based on users takes effect, HSUPA

2 ms TTI is less likely to be switched to HSUPA 10 ms TTI.

This improves users experience but leads to more resource

consumption.

When this switch is turned off and the algorithm of

differentiated fairness based on users takes effect, HSUPA

2 ms TTI is more likely to be switched to HSUPA 10 ms TTI.

V900R013C00SPH532

When this switch is turned on, more HSUPA UEs use 10 ms

TTI and HSUPA UEs are more likely to access the network.

When this switch is turned off, more HSUPA UEs use 2 ms

TTI during initial access, consuming more resources. As a

result, UEs are more likely to fall back from HSUPA

channels to R99 channels to set up services. The total

number of HSUPA UEs may decrease.

V900R013C00SPH532

When this switch is turned on, the PS RAB establishment

success rate may decrease and the handover success rate

may increase if code, credit, or power resources areinsufficient.

If the target cell Ec/No reported by a UE is lower than or

equal to the Ec/No threshold and the uplink BE service

meets the HSUPA bearer conditions, the uplink BE service

is switched from the E-DCH to the DCH. This prevents call

drops when HSUPA coverage performance is worse than

R99 coverage performance.

V900R012C01SPC506

V900R013

When the FACH is congested in a cell, reserving FACH

resources reduces the number of D2F state transitions but

increases the load on DCHs. The reserved FACH resources

can be used for P2F procedures. Therefore, the P2F success

rate increases.

V900R012C01SPH222

V900R013C00SPC510

This threshold is a relative threshold for event 6A. If the
