the UL cell load factor (based on RTWP) can be used to describe UL load


Downlink Load Definition


The transmission power is used to describe DL load


The Objectives of Load Control Load control algorithm can be classified into three parts according to the different

working states of UE Before UE accesses the PUC algorithms will function RNC will monitor the cell load

periodically If the current cell load exceeds a specific threshold RNC will modify the cell selection and re-selection parameters in order that UE can select the low-load cell easily when UE will initiate some services and work at CELL-DCH state This algorithm aims at UE which working at IDLE mode CELL-FACH state CELL-PCH state or URA-PCH state in this cell

During UE accesses the CAC and IAC algorithms will function RNC will judge whether the new access is admissible

After UE accesses LDR and OLC algorithms will function There are some practical algorithms to decrease the cell load When a cell is in basic congestion the RNC shall select some UEs for inter-frequency handover When a cell is in overload congestion the RNC shall select some UEs to release if failing to release the cell from overload

congestion by BE service TF control

coverage and QoS

Parameters for PUC (1) SPUCHEAVY (Load level division threshold 1)

Value Range 0 to 100 Recommended value 70 namely 70

SPUCLIGHT (Load level division threshold 2) Value Range 0 to 100 Recommended value 45 namely 45

SPUCHYST (Load level division hysteresis) Value Range 0 to 100 Recommended value 5 namely 5


Parameters for PUC Algorithm Switch Set the following parameters through ADD CELLPUC query it through LST CELLPUC and

modify it through MOD CELLPUC SPUCHEAVY (Load level division threshold 1) It is used to decide whether the cell load level is Heavy or not If the load of a cell is equal to or

higher than this threshold the load level of this cell is heavy If the load level of a cell is heavy the PUC algorithm will configure selectionreselection parameters for this cell to lead the UE camping on this cell to reselect another inter-frequency neighboring cell with light load

SPUCLIGHT (Load level division threshold 2) It is used to decide whether the cell load level is Light or not If the load of a cell is equal to or

lower than this threshold the load level of this cell is light If the load level of a cell is light the PUC algorithm will configure selectionreselection parameters for this cell to lead the UE to reselect this cell rather than the previous inter-frequency neighboring cell with heavy load

SPUCHYST (Load level division hysteresis) The hysteresis used while judging cell load level it is used to avoid the unnecessary ping-pong of

a cell between two load levels due to tiny load change


Intra-Frequency Load Balancing


Intra-Frequency Load Balancing The NodeB periodically reports the total TCP of the cell and the LDB periodically triggers the following activities Assessing the cell load level based on the total TCP If the downlink load of a cell is higher than the value of the Cell overload threshold it is an indication that the cell is heavily loaded In this case the transmit power of the PCPICH needs

to be reduced by a step which is defined by the Pilot power adjustment step parameter However if the current transmit power is equal to the value of the Min transmit power of PCPICH parameter no adjustment is performed

If the downlink load of a cell is lower than the value of the Cell underload threshold it is an indication that the cell has sufficient remaining capacity for more load In this case the transmit power of the P-CPICH increases by a step which is defined by the Pilot power adjustment step parameter to help to lighten the load of neighboring cells However if he current transmit power is equal to the value of the Max transmit power of PCPICH parameter no adjustment is performed

Why we need CAC WCDMA is an interference limited system after a

new call is admitted the system load will be increased

We must keep the coverage planed by the Radio Network Planning


Flow chart of CAC


The admission decisionThe admission decision is based on

bull Cell available code resource managed in RNCbull Cell available power resource DLUL load measured in

Node Bbull NodeB resource state that is NodeB credits Reported by

Node Bbull Available Iub transport layer resource that is Iub

transmission bandwidth managed in RNCbull HSDPA user number (only for HSDPA service) bull HSUPA user number (only for HSUPA service)

Only when all of these resources are available can a call be admitted


CAC Code Resource Admission For handover services

The current remaining code resource should be enough for the service

For other R99 services RNC shall ensure the remaining code does not exceed

the configurable thresholds after admission of the new service


Parameters for Code Resource Admission

DLHOCECODERESVSF (DL HandOver Credit and Code Reserved SF) This parameter is the Downlink Credit and Code Reserved by Spread

access of a new service the service will be rejected

CAC Power Resource Admission Algorithm 1 based on ULDL load measurement and load prediction

(RTWP and TCP) The algorithm is easy to implement but it is affected by the result of

RTWP and TCP measurement When RTWP andor TCP measurement value areis

invalidunavailable the CAC will change from algorithm 1 to 2 automatically

Algorithm 2 based on Element Number of User (ENU) The algorithm is no need to measure RTWP and TCP but the

calculation is more complex Algorithm 3 loose call admission control algorithm

Similar to algorithm 1 but the prediction of needed power of a new call will be set to zero

Uplink and Downlink CAC Algorithm 2 - ENU For R99 and HSDPA RAB The RNC uses the

following formula to predict the uplink load factor 1048711 (ENUtotal + ENUnew) ENUmax 1048711 By comparing the forecasted ENU load with the

corresponding threshold the RNC decides whether to accept the access request or not


Uplink and Downlink CAC Algorithm 2 - ENUThe ENUmax of DL is very different from the ENUmax

of ULThe UL ENUmax is calculated by the system

Why we need IAC The disadvantage of CAC

For PS NRT (Non-Real Time) services CAC is not flexible

No consideration about the priority of different users No consideration about Directed Retry after CAC

rejection

ldquoIntelligentrdquo means the algorithm can increase admission successful rate


Why we need IAC IAC can increase admission successful rate through the following

methods1 The data rate of PS service is not fixed so maybe the cell can admit

the UE after the data rate is decreased2 Since the service is non-real time the users can wait a short time

then access to the cell3 The user with high priority can preempt the resource of users with low

priority4 If the load of neighboring cell is not ldquoHeavyrdquo UE may be admitted to

the neighboring cell directly5 The IAC procedure includes rate negotiation DRD preemption and

queuing


IAC ndash Direct Retry based on service Data service can be retry to HSDPA cells for better

Preempting resource

The user with high priority can preempt the resource of users with low priority

Triggering resource for Preemption Power (or ENU) SF (spreading factor) Iub transmission

resource NodeB CE


IAC ndash Preemption The preemption procedure is as follows1 The preemption algorithm determines which radio link sets can be preempted

according to the following preemption rules - High priority user preempt the resource of low priority users - Preempting the resource of users with low priority first - Preempting single service user first - Preempting UEs as few as possible that is choose the UEs that can release the

most resources - Preempting should follow this sequence channelization codes first then Iub

transmission resources radio resources last2 Release resources occupied by candidate UEs3 The requested service uses the released resources to access the network directly

without further admission decision


IAC ndash Directed Retry based on Load Balance Service will be set up to the cell with lightest load The advantages

Keeping the load of the network balanced Supporting higher data rate for the user

LCC (Load Congestion Control LCC (Load Congestion Control) consist of LDR (Load

Reshuffling) and OLC (OverLoad Control) In basic congestion state LDR will be used to

optimize resource distribution the main rules is not to affect the feeling of users as possible as we can

In overload state OLC will be used to release overload state quickly keep system stability and the service of high priority users


LDR (Load Reshuffling) Reasons

When the cell is in basic congestion state new coming calls could be easily rejected by system

The larger these parameters are the more obviously the current cellrsquos load is reduced Its cost is that user feelings are affected and that it gives rise to congestion of the target cell The smaller these parameters are the smaller the amplitude of the load adjusted by LDR Its benefit is that the QoS is guaranteed and the target cell load is stable



21 PUC (Potential User Control)22 CAC (Call Admission Control)23 IAC (Intelligent Admission Control)24 LDR (Load Reshuffling)25 OLC (Overload Control)


OLC (Over Load Control) Reasons

In overload state system is not stable Purpose

Ensuring the system stability and making the system back to the normal state as soon as possible

Triggering of OLC Power resources only


OLC (Over Load Control) In some situations the total power load of the cell may be

higher than the target load To ensure system stability overload congestion must be handled The OLC includes

bull Restricting the TF (Transmission Format) of the BE service bull Choosing and releasing some UEs Only power resources could result in overload congestion Hard

resources such as equivalent user number Iub bandwidth and credit resources do not cause overload congestion


OLC (Over Load Control) Cell overload is an emergent status OLC algorithm can quickly

relieve uplinkdownlink load by TF restriction or user release but may also cause oscillation of the cell load and affect the call drop rate

For the uplink overload means the cellrsquos uplink interference is close to or reaches the limit and may give rise to difficulty in BTS uplink reception and decoding resulting in call drop

For the downlink overload means the downlink transmit power is close to or reaches the limit and the userrsquos downlink inner loop power control cannot be increased as needed because of the BTS power restriction resulting in call drop


OLC Actions - TF Control Target user

Rank the candidate users by the integrate priority the low priority user will be selected

Execution Send the control message to UE (downlink TF control

indication uplink Transport format combination control) to restricts the TFC selection

After the congestion is released the BE service rate will be recovered


OLC Actions - Release of Some UEs Target user (downlink eg)


Execution Releasing the service of the selected user


OLC (Over Load Control)


OLC Actions Cell LDC algorithm switch

1048711 Parameter ID NBMLDCALGOSWITCH 1048711 UL_UU_OLC DL_UU_OLC

Set this parameter through ADD CELLALGOSWITCH MOD CELLALGOSWITCH


Parameters for Triggering of Overload (1) ULOLCTRIGTHD (UL OLC trigger threshold)


ULOLCRELTHD (UL OLC release threshold) Value range 0 to 100 Recommended value 85 namely 85


Parameters for Triggering of Overload (2) DLOLCTRIGTHD (DL OLC trigger threshold)


DLOLCRELTHD (DL OLC release threshold) Value range 0 to 100 Recommended value 85 namely 85 Set these parameters through ADD CELLLDM query it through LST

CELLLDM and modify it through MOD CELLLDM


Parameters for Triggering of Overload The uplink OLC trigger threshold judges whether the system uplink is in overload

status If the cell load is consecutively higher than the threshold for pre-determined times it means the system is in overload status Under this circumstance if the cellrsquos OLC switch is open the system will perform OLC algorithm including fast TF restriction or even user release

The smaller the OLC trigger threshold is the easier the system will be in overload status Since OLC will ultimately use extreme method like user release to lower the load too low value will be very detrimental to the system performance

The smaller the OLC release threshold is the harder for the system to release the overload Since the consequence of overload is not as severe as expected it is desirable to set the two parameters a bit higher given that the difference between OLC trigger threshold and OLC release threshold is fixed

The uplink OLC trigger thresholds must be greater than up OLC release thresholds and the recommended difference between the two thresholds is larger than 10 otherwise maybe the basic congestion state is ldquoPing-Pongrdquo
