Modify Cell LDR Algorithm Parameters(MOD UCELLLDR)

Function

Use this command to modify cell load reshuffling (LDR) algorithm parameters.

Note

1. [DL LDR first action], [DL LDR second action], ..., and [DL LDR tenth action] meet the following conditions:

1) If [DL LDR ith action] is set to NOACT (NO ACTION), the subsequent parameters can only be set to NOACT (NO ACTION).

2) Except NOACT, the following actions cannot be selected repeatedly.

A typical procedure is as follows:

[DL LDR first action] can be selected from {NOACT, INTERFREQLDHO, BERATERED, QOSRENEGO, CSInterRatShouldBeLDHO, PSInterRatShouldBeLDHO,AMRRATERED,MBMSDECPOWER, CODEADJ,CSInterRatShouldNotLDHO,PSInterRatShouldNotLDHO}. Suppose this parameter is set to INTERFREQLDHO.

[DL LDR second action] can only be selected from {NOACT, BERATERED, QOSRENEGO, CSInterRatShouldBeLDHO, PSInterRatShouldBeLDHO,AMRRATERED,MBMSDECPOWER, CODEADJ,CSInterRatShouldNotLDHO,PSInterRatShouldNotLDHO}. Note that INTERFREQLDHO cannot be selected any more.

The rest parameters can be deduced by analog.

2. [UL LDR first action], [UL LDR second action], ..., and [UL LDR eighth action] meet the conditions similar to the above.

3. Service handover is a cell in the RANAP_RAB_ASSIGNMENT_REQ message. Its value range is:

HANDOVER_TO_GSM_SHOULD_BE_PERFORMED

HANDOVER_TO_GSM_SHOULD_NOT_BE_PERFORMED

HANDOVER_TO_GSM_SHALL_NOT_BE_PERFORMED

The inter-RAT handover is made only when this attribute agrees with the LDR action.

4. The parameter of [Dl HandOver Credit and Code Reserved SF] must be not less than the one of [Cell LDR SF reserved threshold]. The parameter of [Dl HandOver Credit and Code Reserved SF] is set in ADD UCELLCAC and MOD UCELLCAC, and they can be listed by LST UCELLCAC.

5. The parameter of [Ul HandOver Credit Reserved SF] must be not less than the one of [Ul LDR Credit SF reserved threshold]. The parameter of [Ul HandOver Credit Reserved SF] is set in ADD UCELLCAC and MOD UCELLCAC, and they can be listed by LST UCELLCAC.

6. The parameter of [Dl HandOver Credit and Code Reserved SF] must be not less than the one of [Dl LDR Credit SF reserved threshold]. The parameter of [Dl HandOver Credit and Code Reserved SF] is set in ADD UCELLCAC and MOD UCELLCAC, and they can be listed by LST UCELLCAC.

Parameter

Parameter ID	Parameter Name	Parameter Description
CellId	Cell ID	Meaning: ID of a cell. For detailed information about this parameter, refer to 3GPP TS 25.401. GUI Value Range: 0~65535 Actual Value Range: 0~65535 Unit: None Default Value: None Recommended Value: None
DlLdrFirstAction	DL LDR first action	Meaning: NOACT: No load reshuffling action is taken. INTERFREQLDHO: The inter-frequency load handover is performed. BERATERED: Channels are reconfigured for the BE service. QOSRENEGO: The renegotiation on the QoS of the uncontrollable real-time service is performed. CSINTERRATSHOULDBELDHO: The inter-RAT SHOULDBE load handover of the CS domain is performed. PSINTERRATSHOULDBELDHO: The inter-RAT SHOULDBE load handover of the PS domain is performed. AMRRATERED (AMR service rate decreasing): The setting of the TFC subset and the negotiation of the service rate can be performed for the AMR voice service. MBMSDECPOWER (MBMS power limiting): The MBMS service is configured with the minimum power. CODEADJ (code tree reshuffling): The fragments of the downlink code tree are arranged. PSINTERRATSHOULDNOTBELDHO: The inter-RAT SHOULDNOTBE load handover of the PS domain is performed. PSINTERRATSHOULDNOTLDHO: The inter-RAT SHOULDNOTBE load handover of the PS domain is performed. The LDR takes the actions in the preset sequence and judges whether each action is successful. If an action is unsuccessful, the LDR turns to the next action. If an action is successful, a parameter is set to NOACT, or all the preceding actions are taken, the downlink LDR is finished, and the system waits for the next triggering of the LDR. Because each action is performed by its algorithm module, the LDR algorithm only selects users and delivers control messages, the execution result of each action can be obtained after a delay, and the LDR algorithm cannot wait for a long time, so the LDR can only judge whether the actions succeed by whether candidate users are found. The inter-frequency load handover has no impact on the QoS of users and can balance the cell load, so the inter-frequency load handover usually serves as the first action. The BE service rate reduction is effective only when the DCCC algorithm is enabled.

If the high-rate subscribers occupy a low proportion, set the parameter to a comparatively high value. Because the basic congestion control algorithm is designed to slowly decrease cell load, you need to set this parameter to a comparatively low value. GUI Value Range: 1~10 Actual Value Range: 1~10 Unit: None Default Value: None Recommended Value: 1
DlLdrAMRRateReductionRabNum	DL LDR-AMR rate reduction RAB number	Meaning: The mechanism of the LDR is that an action is performed in each [LDR period] and some services are selected based on the action rules to perform this action. This parameter defines the maximum number of RABs selected in executing downlink LDR-AMRvoice service rate reduction. If the parameter value is too high, the LDR action may fluctuate greatly and over control may occur (the state of basic congestion turns into another extreme--under load). If the parameter value is too low, the LDR action has a slow response and the effect is not apparent, affecting the LDR performance. GUI Value Range: 1~10 Actual Value Range: 1~10 Unit: None Default Value: None Recommended Value: 1
DlCSInterRatShouldNotHOUeNum	DL CS should not be HO user number	Meaning: Number of users selected in a DL LDR CS domain inter-RAT SHOULDNOTBE load handover.

UlPSInterRatShouldNotHOUeNum	UL PS should not be HO user number	Meaning: Number of users selected in a UL LDR PS domain inter-RAT SHOULDNOTBE load handover. The target subscribers of this parameter are the PS domain subscribers. In the actual system, this parameter can be set on the basis of the actual circumstances. If the high-rate subscribers occupy a high proportion, set the parameter to a comparatively low value. If the high-rate subscribers occupy a low proportion, set the parameter to a comparatively high value. Because the basic congestion control algorithm is designed to slowly decrease cell load, you need to set this parameter to a comparatively low value. GUI Value Range: 1~10 Actual Value Range: 1~10 Unit: None Default Value: None Recommended Value: 1
UlInterFreqHoCellLoadSpaceThd	UL HO load space threshold	Meaning: The inter-frequency neighboring cell could be selected as the destination of load handover only when its load remaining space is larger than this threshold. The lower the parameter is, the easier it is to find a qualified target cell for the blind handover. Excessively small value of the parameter, however makes the target cell easily enter the congestion status. The higher the parameter is, the more difficult it is for the inter-frequency blind handover occurs. GUI Value Range: 0~100 Actual Value Range: 0~1, step:0.01 Unit: per cent Default Value: None Recommended Value: 20
DlInterFreqHoCellLoadSpaceThd	DL HO load space threshold	Meaning: The inter-frequency neighboring cell could be selected as the destination of load handover only when its load remaining space is larger than this threshold. The lower the parameter is, the easier it is to find a qualified target cell for the blind handover. Excessively small value of the parameter, however makes the target cell easily enter the congestion status. The higher the parameter is, the more difficult it is for the inter-frequency blind handover occurs. GUI Value Range: 0~100 Actual Value Range: 0~1, step:0.01 Unit: per cent Default Value: None Recommended Value: 20
UlInterFreqHoBWThd	UL HO maximum bandwidth	Meaning: The UE can be selected to process load handover only when its bandwidth is less than this threshold. GUI Value Range: 0~400000 Actual Value Range: 0~400000 Unit: bit/s Default Value: None Recommended Value: 200000
DlInterFreqHoBWThd	DL HO maximum bandwidth	Meaning: The UE can be selected to process load handover only when its bandwidth is less than this threshold. GUI Value Range: 0~400000 Actual Value Range: 0~400000 Unit: bit/s Default Value: None Recommended Value: 200000
MbmsDecPowerRabThd	MBMS descend power rab threshold	Meaning: When the priority of the RAB of MBMS services exceeds this threshold, reconfigure the MBMS power to the minimum power. The MBMS service at each rate is set on the basis of two power levels. The power set for an MBMS service is determined according to cell load during the service access. In addition, the FACH power of the MBMS service must be decreased as required in the duration of cell congestion. Some services with high priority, for example the disaster pre-alert, however, do not need the coverage shrink caused by cell load. In such a case, you can adjust the service priority threshold to protect the services with high priority against the impact of the service access failure and the load control algorithm. GUI Value Range: 1~15 Actual Value Range: 1~15 Unit: None Default Value: None Recommended Value: 1
CellLdrSfResThd	Cell LDR SF reserved threshold	Meaning: Cell SF reserved threshold. The code load reshuffling could be triggered only when the minimum available SF of a cell is higher than this threshold.

LdrCodePriUseInd	LDR code priority indicator	Meaning: FALSE means not considering the code priority during the code reshuffling. TRUE means considering the code priority during the code reshuffling. If the parameter is TRUE, the codes with high priority are reserved during the code reshuffling. It is good for the code resource dynamic sharing, which is a function used for the HSDPA service. GUI Value Range: FALSE(FALSE), TRUE(TRUE) Actual Value Range: FALSE, TRUE Unit: None Default Value: None Recommended Value: FALSE
MaxUserNumCodeAdj	Max user number of code adjust	Meaning: This parameter specifies the number of users selected in code reshuffling. Code reshuffling can be triggered only when the number of users on a code is no greater than the threshold. Code reshuffling has a big impact on the QoS. In addition, the reshuffled subscribers occupy two code resources during code reshuffling. Thus, the parameter should be set to a comparatively low value. GUI Value Range: 1~3 Actual Value Range: 1~3 Unit: None Default Value: None Recommended Value: 1
UlLdrCreditSfResThd	Ul LDR credit SF reserved threshold	Meaning: Reserved SF threshold in uplink credit LDR. The uplink credit LDR could be triggered only when the SF factor corresponding to the uplink reserved credit is higher than the uplink or downlink credit SF reserved threshold. GUI Value Range: SF4(SF4), SF8(SF8), SF16(SF16), SF32(SF32), SF64(SF64), SF128(SF128), SF256(SF256) Actual Value Range: SF4, SF8, SF16, SF32, SF64, SF128, SF256 Unit: None Default Value: None Recommended Value: SF8
DlLdrCreditSfResThd	Dl LDR credit SF reserved threshold	Meaning: Reserved SF threshold in downlink credit LDR. The downlink credit LDR could be triggered only when the SF factor corresponding to the downlink reserved credit is higher than the uplink or downlink credit SF reserved threshold. GUI Value Range: SF4(SF4), SF8(SF8), SF16(SF16), SF32(SF32), SF64(SF64), SF128(SF128), SF256(SF256) Actual Value Range: SF4, SF8, SF16, SF32, SF64, SF128, SF256 Unit: None Default Value: None Recommended Value: SF8
LdrCodeUsedSpaceThd	InterFreq HO code used ratio space threshold	Meaning: Code resource usage difference threshold. Inter-frequency handover is triggered when the difference of the resource usage of the current cell and that of the target cell is greater than this threshold. GUI Value Range: 0~100 Actual Value Range: 0~1, step:0.01 Unit: per cent Default Value: None Recommended Value: 13
CodeCongSelInterFreqHoInd	Code congestion select inter-freq indication	Meaning: This switch is valid only when the inter-frequency handover switch is enabled. TRUE means that inter-frequency handover is selected in code resource congestion. FALSE means that inter-frequency handover is not selected in code resource congestion. This parameter should be set based on network resource usage. In the case of multi-frequency coverage, if code resources present a bottleneck, such as indoor environment, the parameter is recommended to be set to TRUE. GUI Value Range: FALSE(FALSE), TRUE(TRUE) Actual Value Range: FALSE, TRUE Unit: None Default Value: None Recommended Value: FALSE
GoldUserLoadControlSwitch	Gold user load control switch	Meaning: Indicates whether gold users involve in the switch of congestion control. According to the policy set for gold users by operators, if service quality of gold users should be guaranteed even in resource congestion, the switch should be disabled. If the switch is enabled, LDR such as rate reduction and handover also occurs on gold users even in cell resource congestion, which impacts user service quality. If the switch is disabled, no action is performed on gold users. GUI Value Range: OFF(OFF), ON(ON) Actual Value Range: OFF, ON Unit: None Default Value: None Recommended Value: OFF

Traffic Parameters - HUAWEI - BSC 6900

Traffic Parameters

Traffic parameters refer to the parameters used by each PVC for flow control. The traffic parameters include traffic rate and delay variation.

Table 1 describes the ATM traffic parameters.

Table 1 ATM traffic parameters

Parameter Name	Parameter ID	Description
Traffic record index	TRFX	Identifies a traffic record.
Service Type	ST	Indicates the type of service carried over ATM. CBR and RT-VBR indicate real-time services, which are usually carried on the user planes of the Iur, Iub, and Iu-CS interfaces. NRT-VBR and UBR indicate non-real-time services, which are usually carried on the user plane of the Iu-PS interface.
Rate unit	UT	Indicates the unit of PCR, SCR, and MCR.
Peak cell rate	PCR	Indicates the maximum rate of transmitting ATM cells.
Sustainable cell rate	SCR	Indicates the average rate of transmitting ATM cells over a long time.
Minimum cell rate	MCR	Indicates the minimum rate of transmitting ATM cells.
Max burst size	MBS	Indicates the maximum number of continuous ATM cells.
Cell delay variation tolerance	CDVT	Indicates the maximum tolerable variation in the unit of 0.1 μs.
Traffic use description	REMARK	Describes the usage of the ATM traffic record.

The traffic rate is indicated in the following ways:

• PCR: applicable when Service type is set to CBR and the traffic rate is a constant value.
• Combination of PCR and SCR: applicable when Service type is set to RTVBR or NRTVBR.
• MCR: applicable when Service Type is set to UBR_PLUS.

VPI and VCI

The main characteristics of the ATM technology are multiplexing, switching, and transmitting of ATM cells. All these operations are performed over Virtual Channels (VCs). A VC and a Virtual Path (VP) are identified by Virtual Channel Identifier (VCI) and Virtual Path Identifier (VPI) respectively.

Figure 1 shows the relation between VC and VP.

• A VC is identified by a VCI. It is a logical connection between ATM nodes and is the channel for transmitting ATM cells between two or more nodes. The VC is used for the data transmission between mobile terminals, between networks, or between mobile terminal and network.
• A VP is a group of VCs at a given reference point. The VCs in the group have the same VPI.

Figure 1 Relation between VC and VP

Service Type

The ATM services are of four types: Constant Bit Rate (CBR), Real-Time Variable Bit Rate (RT-VBR), Non-Real-Time Variable Bit Rate (NRT-VBR), and Unspecified Bit Rate (UBR).

Table 1 describes the types of service.

Table 1 Types of service

Type of Service	Abbreviation	Description
Constant Bit Rate	CBR	No error check, flow control, or other processing
Real-Time Variable Bit Rate	RT-VBR	Rate of a service with variable-rate data streams and strict real-time requirements, for example, interactive compressed video (video telephony).
Non-Real-Time Variable Bit Rate	NRT-VBR	Rate of a service that is applicable to timing transmission. A service of this type, for example, e-mail, is relatively insensitive to delivery time or delay.
Unspecified Bit Rate	UBR	Rate of a service with no commitment to transmission and no feedback on congestion. This type of service is ideal for the transmission of IP datagrams. In congestion, UBR cells are discarded, and no feedback or request for slowing down the data rate is delivered to the transmission end.

Table 2 describes the characteristics of different ATM services.

Table 2 Characteristics of different ATM services

Characteristic	CBR	RT-VBR	NRT-VBR	UBR
Bandwidth guarantee	Yes	Yes	Yes	No
Applicability to real-time communication	Yes	Yes	No	No
Applicability to bursts of communication	No	No	Yes	Yes
Feedback on congestion	No	No	No	No
