2 Overview

2.1 Background

Special events, such as festivals, parades, or major demonstrations, often result in unpredictable

network congestion depending on crowd levels and community participation. In this case,

network configuration optimization cannot be performed in advance. With Automatic

Congestion Handler, congestion relief can be performed automatically in these scenarios.

2.2 Introduction

Automatic Congestion Handler monitors network congestion in real time. If network congestionoccurs, this feature automatically performs corresponding congestion relief actions based on the

congestion state. This relieves network congestion.

2.3 Benefits

This feature automatically relieves congestion in scenarios where special events result in

unanticipated crowd levels, thereby reducing the operation and maintenance workload. This

improves system stability and performance.

3 Technical Description

3.1 IntroductionThis feature monitors load-related measurement quantities for a cell in real time. If a

measurement quantity or a set of measurement quantities meets certain requirements, the RNC

determines that the cell is congested and performs corresponding congestion relief actions, which

can be implemented by activating existing congestion relief algorithms or adjusting the settings

of existing network configuration parameters.

3.2 PrinciplesWhen the automatic congestion control switch (ADAP_CELL_CONGEST_SWITCH under

the AdapAlgoSwitch(BSC6900,BSC6910) parameter) is set to on, the RNC determines the

congestion state of a cell based on measurement quantities such as downlink non-HSPA power

load, actual uplink load, and number of users on the FACH.

After determining the congestion state, the RNC performs corresponding congestion relief

actions to improve the cell performance. Figure 3-1 outlines the mapping between congestion

states and congestion relief actions.

NOTE

The preceding figure shows only the working principle of the automatic congestion control algorithm. For

details about how to determine the congestion states in actual conditions, see section 3.2.1 Decision

Conditions for Different Congestion States.

3.2.1 Decision Conditions for Different Congestion States

The RNC determines the load state of a cell based on the following measurement objects:

l Downlink power load of a cell: This measurement object includes the downlink non-HSPA

power load. For details about the downlink non-HSPA power load, see Load Measurement

Feature Parameter Description.

l Uplink power load of a cell: This measurement object includes the actual uplink load, uplink

rise over thermal (RoT) or received total wideband power (RTWP) and number of users

on the DCH.

NOTE

If the actual uplink load cannot be obtained, the uplink RoT is used instead. For details about the

actual uplink load, see Load Measurement Feature Parameter Description.

l FACH of a cell: The state of each channel carried over the FACH determines whether the

FACH of a cell is congested.

l Number of users on the FACH: This is determined based on the number of users in the

CELL_FACH state.

Table 3-1 describes the decision conditions for each measurement object.

3.2.2 Automatic Congestion Relief Actions

The RNC performs corresponding congestion relief actions after determining the load state of

a cell. Table 3-2 lists all the congestion relief actions for each congestion state. Some functionsunder CS Preference and FACH Congestion Control have no negative impact on the network

when the cell is not congested. Therefore, these functions are enabled by default when the

ADAP_CELL_CONGEST_SWITCH under the AdapAlgoSwitch(BSC6900,BSC6910)

parameter is set to ON and corresponding conditions are met. Once enabled, these functions will

not be disabled.

NOTE

l CS Preference includes the following functions: CS RAB setup optimization, CS services preempting

PS BE service resources, preemption algorithm, CS RRC preemption, high SPU CPU load preemption.

l FACH Congestion Control includes the following functions: RLC transmission suspension after UL

4A, RLC transmission suspension after DL F2D, P2D in FACH congestion, TVM-based P2D, and F2P

state transition through physical channel reconfiguration.

5 Network Impact

System Capacity Network configuration optimization cannot be performed in advance for special events where

unanticipated network congestion often occurs. With Automatic Congestion Handler,

congestion relief can be performed automatically when cells are congested. This improves

system capacity. This feature involves multiple algorithms and functions.

The impact of each algorithm or function on system capacity is as follows:

l N300/T300 parameter optimization: This function reduces the number of RRC

CONNECTION REQUEST retransmissions in congestion scenarios and therefore reduces

additional resource consumption in the uplink. When there are sufficient services, this

action also increases the uplink traffic volume.

l RRC connection release wait time parameter optimization: This function prolongs the time

a user of low-priority has to wait before sending a second RRC CONNECTION REQUEST

message and reduces additional resource consumption in the uplink in congestion scenarios.

When there are sufficient services, this action also increases the uplink traffic volume.

l Cell HSUPA user number parameter optimization: This function reduces the maximum

number of online HSUPA users in a cell in congestion scenarios. The uplink throughput is

low in congestion scenarios and the power efficiency of R99 services is higher than that of

HSUPA services in low uplink throughput scenarios.Eventually, this action reduces the

resource consumption in the uplink. When there are sufficient services, this action also

increases the total uplink traffic volume.

l Uplink or downlink initial access rate: This function decreases the initial access rate of R99users that are processing PS BE services and reduces the power consumption per user in

congestion scenarios. When there are sufficient services, this action also increases the

number of users on the DCH and improves system capacity.However, this reduces the

average throughput of a single user that is processing PS BE services.

l Functions under CS Preference, such as CS RAB setup optimization and CS services

preempting PS BE service resources, ensure that CS services preferentially access the

network. This improves the CS Erlangs but reduces the PS traffic volume in congestion

scenarios.

l Functions under FACH Congestion Control, such as RLC transmission suspension after

UL 4A, improve the utilization of FACH resources and therefore improve the system

capacity in congestion scenarios.

Description 5 Network Impact

l RxLevMin parameter optimization: This function increases the value of the RxLevMin

parameter when a cell enters the congestion state so that some UEs will not camp on this

cell. This affects the cell capacity but realizes load balancing, without affecting system

capacity.

l HSDPA user number restriction cancellation: This function increases the number of admitted HSDPA users.

l DPCH pilot power adjustment: When the downlink load is heavy due to heavy traffic, this

function reduces downlink DPCH power consumption by reducing the length and power

offset of the pilot field. Ultimately, system capacity is increased.

The overall impact on system capacity is as follows:

In cell congestion scenarios, congestion relief actions help reduce cell load and improve the

efficiency of resource utilization. This feature also helps improve cell capacity when there are

sufficient services.

Network Performance

The impact of each algorithm or function on network performance is as follows:

l N300/T300 parameter optimization: This function reduces the number of RRC

CONNECTION REQUEST retransmissions in congestion scenarios. This extends the

response delay users experience.

l RRC connection release wait time parameter optimization: This function prolongs the time

a user of low-priority must wait before sending a second RRC CONNECTION REQUEST

message in congestion scenarios.This extends the response delay these users experience.

l Cell HSUPA user number parameter optimization: This function reduces the maximumnumber of online HSUPA users in a cell in congestion scenarios.As a result, some HSUPA

users can be carried only on the DCH, affecting user experience.

l Inter-RAT redirection: This function enables users to be redirected to the GSM network

after failing to access the UMTS network.This reduces the access delay for these users,

improving user experience.

l Inter-RAT DRD: This function enables CS users to access the GSM network after failing

to access the UMTS network in congestion scenarios. This reduces the access delay for

these users and slightly improves the setup success rate of CS services.

l Functions under CS Preference, such as CS RAB setup optimization and CS services

preempting PS BE service resources, ensure that CS services preferentially access thenetwork. This improves the CS RAB setup success rate in congestion scenarios. However,

the PS call drop rate slightly increases if the occurrences of CS or PS services preempting

resources occupied by PS services increase.

l Cell-level static CAPS flow control or cell-level dynamic CAPS flow control: This function

decreases the number of allowable RRC connections in heavy traffic scenarios, affecting

the RRC connection setup success rate.

l DPCH pilot power adjustment: If the length or power offset of the pilot field is reduced,

SIR estimations will become less accurate and Uu-interface synchronization probability is

reduced. This increases the call drop rate.

The overall impact on network performance is as follows:

WCDMA RAN





19



If CS admission fails before this feature is enabled, the CS access success rate significantly

increases after this feature is enabled.However, the PS call drop rate also increases when PS or

CS preemption occurs.

NOTE

l After this feature is enabled, some of the preceding functions take effect simultaneously and affect

each other.Therefore, the impact of this feature on system capacity and network performance cannot

be quantified.

l After this feature is enabled, the RNC dynamically adjusts parameters and therefore the CPU usage of

the SPU subsystem slightly increases. The increase in the CPU usage is in direct proportion to the

number of cells enabled with this feature on the SPU subsystem. When all the cells on the SPU

subsystem are enabled with this feature, the CPU usage of the SPU subsystem increases by less than

3%.

6 Engineering Guidelines

6.1 When to Use Automatic Congestion Handler

The Automatic Congestion Handler feature is recommended in the following scenarios:

l The network configuration involved in this feature is not optimized.

l Unplanned events happen. It is recommended that this feature always be enabled in this

scenario because network congestion often occurs and the congestion state is unpredictable

in this scenario.

l A cell is congested. This feature helps relieve cell congestion and improves system capacity.

For details about how to determine whether the network configuration needs to be optimized

and whether a cell is congested, see section 6.2 Required Information

6.2 Required Information

l Collect the values of the VS.CellDCHUEs(BSC6900,BSC6910),

VS.MeanULActualPowerLoad(BSC6900,BSC6910), VS.MeanRTWP

(BSC6900,BSC6910), VS.MeanTCP.NonHS(BSC6900,BSC6910) ,

VS.CellFACHUEs.MAX(BSC6900,BSC6910), and VS.CellFACHUEs

(BSC6900,BSC6910) counters during busy hours to evaluate the congestion states of

different resources in a cell. When the counters meet the following conditions, thecorresponding resource in the cell is congested.It is recommended that this feature be

enabled for a cell if any resource is congested. Then, based on the triggering conditions of

congestion relief actions (described in 3.2.1 Decision Conditions for Different

Congestion States and 3.2.2 Automatic Congestion Relief Actions), evaluate whether a

corresponding function has taken effect. The heavier the cell load is, the more significant

gains a function provides.

– The uplink power load meets the following conditions:

The value of the VS.CellDCHUEs(BSC6900,BSC6910) counter is greater than 20.

The value of the VS.MeanULActualPowerLoad(BSC6900,BSC6910) counter is

greater than 65%. That is, the actual uplink load is greater than 5 dB. If the actual uplink

load cannot be obtained, this feature uses the RTWP instead. In this case, it is required

that the RoT corresponding to the value of the VS.MeanRTWP

(BSC6900,BSC6910) counter be greater than 5 dB.

– For the downlink power load, the value of the VS.MeanTCP.NonHS

(BSC6900,BSC6910) counter meets the following formula: 10[(VS.MeanTCP.NonHS

(BSC6900,BSC6910)- MaxTxPower /10)/10] > 60%.

– For the number of users on the FACH, the value of the VS.CellFACHUEs

(BSC6900,BSC6910) counter is greater than 25 or the value of the

VS.CellFACHUEs.MAX(BSC6900,BSC6910) counter is greater than or equal to 30.

l Check the settings of related parameters and determine whether this feature is necessary

based on the congestion relief actions described in 3.2.2 Automatic Congestion Relief

Actions.

VS.MeanULActualPowerLoad(BSC6900,BSC6910), VS.MeanRTWP(BSC6900,BSC6910), and VS.CellFACHUEs(BSC6900,BSC6910) counters before and

after this feature is activated.

l When the function of Cell HSUPA user number parameter optimization is enabled in a cell

where the uplink power load is congested, if the value of the VS.HSUPA.UE.Max.Cell

(BSC6900,BSC6910) counter is greater than half the value of the MaxHsupaUserNum

counter before the feature activation, the value of the VS.HSUPA.UE.Mean.Cell

(BSC6900,BSC6910) counter decreases after the feature activation.

l When CS Preference functions such as CS RAB setup optimization and CS services

preempting PS BE service resources are enabled in a congested cell, if CS admission fails

before this feature is activated, the AMR RAB setup success rate and number of CS users

increase after this feature is activated. However, the PS call drop rate also increases whenPS or CS preemption occurs.

l When the maximum number of FACH users is greater than or equal to 30 before this feature

is activated and the function of increasing number of UEs on FACH to 60 is enabled, the

value of the VS.CellFACHUEs(BSC6900,BSC6910) counter increases after the feature

activation.

Changes in the cell load are as follows:

l After this feature is activated in a congested cell, the cell load decreases and resource usage

increases. In addition, the cell traffic increases when there are sufficient service demands.

(BSC6900,BSC6910) and VS.MeanTCP.NonHS(BSC6900,BSC6910) counters,

respectively.

NOTE

If the value of the VS.MeanRTWP(BSC6900,BSC6910) counter does not decrease, the reason may be

that the total uplink PS traffic volume (the sum of uplink PS R99 traffic volume over the Iub and the HSUPAtraffic volume) slightly increases.

If the value of the VS.MeanTCP.NonHS(BSC6900,BSC6910) counter does not decrease, the reason may

be that the total downlink PS traffic volume (the sum of downlink PS R99 traffic volume over the Iub

interface and the HSDPA traffic volume) slightly increases.

Observe capacity gains as follows:

l Uplink capacity gains

– Use VS.CellDCHUEs(BSC6900,BSC6910) and the total uplink PS traffic volume of

a cell to observe the overall throughput gain. Specifically, create a scatter chart by using

the value of VS.CellDCHUEs(BSC6900,BSC6910) as the horizontal coordinate and

the total uplink PS traffic volume of a cell as the vertical coordinate to determine thethroughput gain with the user number unchanged.

– Use VS.CellDCHUEs(BSC6900,BSC6910) and VS.MeanRTWP

(BSC6900,BSC6910) to determine the overall RTWP gain. That is, create a scatter

diagram by using the value of VS.CellDCHUEs(BSC6900,BSC6910) as the horizontal

coordinate and the value of VS.MeanRTWP(BSC6900,BSC6910) as the vertical

coordinate to determine the RTWP gain with the user number unchanged.

The total uplink PS traffic volume of a cell can be calculated as follows:

VS.SRNCIubBytesHSUPA.Rx(BSC6900,BSC6910) +

VS.SRNCIubBytesPSR99Conv.Rx(BSC6900,BSC6910) +

VS.CRNCIubBytesPSR99.CCH.Rx(BSC6900,BSC6910).

l Downlink capacity gains

– Use VS.CellDCHUEs(BSC6900,BSC6910) and the total downlink PS traffic volume

of a cell to observe the overall throughput gain. Specifically, create a scatter chart by

using the value of VS.CellDCHUEs(BSC6900,BSC6910) as the horizontal coordinate

and the total downlink PS traffic volume of a cell as the vertical coordinate to determine

the throughput gain with the user number unchanged.

– Use VS.CellDCHUEs(BSC6900,BSC6910) and VS.MeanTCP.NonHS

(BSC6900,BSC6910) to determine the downlink power gain. Specifically, create a

scatter chart by using the value of VS.CellDCHUEs(BSC6900,BSC6910) as thehorizontal coordinate and the value of VS.MeanTCP.NonHS(BSC6900,BSC6910) as

the vertical coordinate to determine the downlink power gain with the user number

unchanged.

The total downlink PS traffic volume of a cell can be calculated as follows:

VS.SRNCIubBytesHSDPA.Tx(BSC6900,BSC6910) +

VS.SRNCIubBytesPSR99Conv.Tx(BSC6900,BSC6910) +

VS.SRNCIubBytesPSR99Str.Tx(BSC6900,BSC6910) +

You are advised to use the data one week before and after feature activation to determine the

feature gain.

Use VS.CellDCHUEs(BSC6900,BSC6910) and VS.MeanRTWP(BSC6900,BSC6910) to

evaluate the load performance gain at the RNC- or cluster-level as follows: As shown in the

following figure, after this feature is enabled, the average RTWP decreases with the same number

of online users. In addition, the larger the number of online users, the more significant the

decrease in the average RTWP. That is, the uplink load performance is significantly improved

after this feature is enabled.

Use VS.CellDCHUEs(BSC6900,BSC6910) and the total uplink PS traffic volume of a cell to

evaluate the uplink throughput gain at the RNC- or cluster-level as follows: As shown in the

following figure, after this feature is enabled, the total traffic volume in the uplink increases with

the same number of online users. In addition, the larger the number of online users, the more

significant the increase in the throughput. That is, the overall network throughput is significantly

improved after this feature is enabled.

Meaning: Timer for the transmitting side of a PS TRB

AM RLC entity to wait for a response from the peer end

after sending the peer end polling RLC PDUs in the

CELL_FACH state. This parameter takes effect only

when the transmitting side of an AM RLC entity is

configured with the polling function. The transmitting

side of an AM RLC entity starts this timer after sending

polling RLC PDUs to the peer end. If the transmitting

side does not receive any status report from the peer end

after this timer expires, the transmitting side retransmits

polling RLC PDUs and restarts this timer. For details

about this parameter, see 3GPP TS 25.322.

is dynamically adjusted based on the DRD success rate.

When this switch is set to ON, the RNC dynamically

adjusts the value of "PathlossThdForCenter" based on

the success rate of UE location-based multi-DRD.

When the DRD success rate is greater than a predefined

threshold, the RNC increases the value of

"PathlossThdForCenter". When the DRD success rateis lower than a predefined threshold, the RNC decreases

the value of "PathlossThdForCenter". When this switch

is set to off, the value of "PathlossThdForCenter" is

automatically changed to that before the adjustment.

PREEMPT_ENH_NODEB_PREEMPT_CE_SWITC

H: Whether to activate CE-based user preemption on the

NodeB side. If this switch is turned on, the RNC sends

the NodeB a user list containing users that can be

preempted. The NodeB selects users for preemption

based on the consumed CEs.

2.

PREEMPT_ENH_HSSCCH_PREEMPT_SF_SWITC

H: Whether channel codes can be obtained by

preempting SF resources of R99 users when HS-SCCHchannels are being established.When this switch is

turned on, the RNC preempts SF resources occupied by

R99 users to set up HS-SCCHs.When the switch is

turned off, the RNC searches for vacant SF resources to

set up HS-SCCHs in scenarios where SF resources are

occupied by R99 users. Value of this bit field will be

removed from later versions. Although the

configuration interface in this version supports delivery

of the setting of this bit field, the system does not use

this bit field. Therefore, this bit field is not

recommended.

3.

PREEMPT_ENH_CSRRC_PREEMPT_PS_SWITCH

: Whether RRC connection requests for CS services

preempt resources for PS services when cell resources

are insufficient.When this switch is turned on, CS

services preempt resources occupied by PS services to

access the cell, if RRC connection requests for CS

services fail due to insufficient cell resources.When this

switch is turned off, RRC connection requests for CS

services cannot initiate a preemption for resources

occupied by PS services.

4.

PREEMPT_ENH_CSRAB_PREEMPT_PS_SWITCH

: Whether CS access requests preempt resources for PS

services when cell resources are insufficient.When this

switch is turned on, CS services preempt resources

resources due to insufficient cell resources and cannot

preempt other users' resources when the CPU usage is

higher than 70%. When this switch is turned off, the user

does not consider the CPU load when preempting other

users' resources.

6.

PREEMPT_ENH_RRC_RAB_COMBINE_SWITCH:

Whether to combine radio resources of UEs that have

RRC connections and UEs that are allocated RABs

when the preempting UE is allowed to preempt radio

resources of multiple UEs. If this switch is turned on,

the RNC combines radio resources of these two types

of UEs when preemption is required due to insufficient

radio resources. If this switch is turned off, the

preempting UE can preempt radio resources of only UEs

that have RRC connections or UEs that have been

allocated RABs.

7.

PREEMPT_ENH_PT_USER_PREEMPT_ENH_SWI

TCH: Whether to support the preemption enhancement

function for platinum users. When this switch is set to

on, platinum users can preempt resources of other users

if cell admission fails during the DRD, channel fallback,

or rate re-negotiation during admission control

procedure. When this switch is set to on, platinum users

perform the same actions as common users. That is,

DRD, channel fallback, rate re-negotiation during

admission control, and preemption are performed in

sequence.

8.

PREEMPT_ENH_DRNC_CS_RAB_PREEMPT_SW

ITCH: Whether to trigger the preemption function

during a CS RAB setup under the DRNC. When this

switch is set to on, preemption is triggered during a CS

RAB setup under the DRNC. When this switch is set to

off, preemption is not triggered during a CS RAB setup

under the DRNC.

PREEMPT_ENH_MULTIRAB_CS_INCR_PMT_S

WITCH: Whether to optimize the PS service bearing

policy and CS resource preemption when a UE that has

already had PS RABs attempts to set up a CS RAB but

the CS RAB setup fails and resource preemption is

triggered.When this switch is set to on, if a UE that has

already had PS RABs in the CELL_DCH state attempts

to set up a CS RAB but the CS RAB setup fails and

resource preemption is triggered, PS services can still

be carried on channels using more advanced

technologies and the UE preempts only the incremental

resources required for the CS RAB setup. When this

switch is set to off, PS services must be switched back

to R99 channels when resource preemption is triggered

and the UE preempts the resources required for

processing all the ongoing services.

11.PREEMPT_ENH_MULTIRAB_PRIO_OPT_SWI

TCH: Whether to prevent PS RABs from triggering

preemption if a UE that has already had a CS RAB

attempts to set up PS RABs when the forcible CS

preemption policy is used in combined service

scenarios.When the forcible CS preemption policy

(controlled by the


under the "PreemptEnhSwitch" parameter) is used and

this switch is set to on, if a UE that has already had a CS

RAB attempts to set up PS RABs, preemption cannot

be triggered for PS services if PS RAB admission fails.

When the forcible CS preemption policy is used and this

switch is set to off, preemption can be triggered for SPservices if PS RAB admission fails.

12. PREEMPT_ENH_PS_IU_CS_PMTED_SWITCH:

Whether resources of a PS user who has sent requests

of setting up CS connections but the CS RABs have not

been established can be preempted. When this switch is

turned on, resources of the PS user cannot be preempted

before the CS RABs are established. When this switch

is turned off, resources of the PS user can be preempted

before the CS RABs are established.

25. CFG_PTT_SWITCH: When this switch is on, the

RNC identifies the PTT user based on the QoS attributes

in the RAB assignment request message. Then, the PTT

users are subject to special processing.

26. CFG_RAB_REL_RMV_HSPAPLUS_SWITCH:

When this switch is on and if an RAB release is

performed, the RNC decides whether to fall back a

certain HSPA(HSPA+) feature based on the

requirement of remaining traffic carried by the UE. That

is, if an HSPA+ feature is required by the previously

released RAB connection but is not required in the

initial bearer policy of the remaining traffic, the RNC

falls back the feature to save the transmission resources.

The HSPA+ features that support the fallback are

MIMO, 64QAM, MIMO+64QAM, UL 16QAM, DC-

HSDPA, UL TTI 2ms, and DC-HSUPA.

RRC connections): When this switch is turned off, the

number of allowed prioritized RRC connection setup

requests is calculated based on the following:

Number of allowed RRC connection setup requests per

second

Number of RRC connection setup requests that can be

borrowed from that reserved for the next second

When this switch is turned on, high-priority RRC

connection setup requests can use 20-30% more of the

requests allowed for the next second. This increases the

number of allowed high-priority RRC connection setup

requests per second.

3. CS_RRC_CELL_DYN_CAPS_FC_OPT_SWITCH

(CS Cell Dynamic CAPS FC Optimization Switch):When this switch is turned on, the RNC does not

perform cell-level dynamic CAPS flow control on CS

services. When this switch is turned off, the RNC

performs cell-level dynamic CAPS flow control on CS

services.

Meaning:The parameter values are described as follows:

1.



Message): Whether to enable queue-based shaping for

CELL_UPDATE messages. When this switch is turned

on, queue-based shaping for CELL_UPDATE

messages is enabled. If the CPU usage is high when a

UE initiates a cell update, the RNC buffers the received

CELL_UPDATE messages of the different priorities in

different queues. When the CPU usage falls below athreshold, the RNC processes the buffered messages.
