2 Overview
Special events, such as large gatherings, concerts, and sporting events, often result in suddenand dramatic increases in traffic. On multi-carrier networks with preferred camping, suchincreases in traffic usually lead to access congestion in preferentially camped cells and causekey performance indicators (KPIs) to deteriorate. To alleviate access congestion and increasethe radio resource control (RRC) connection setup success rate, the Camping Strategy Switchfor Mass Event feature changes the network camping strategy from preferred camping to randomcamping.

2.1 DefinitionPreferred Camping Preferred camping is often used together with the service steering function.When this strategy is used: A UE in idle mode preferentially camps on a cell deliveringcontiguous coverage. This cell then becomes the UE's preferentially camped cell. When the UEinitiates an R99 service, the RNC instructs the UE to process the service in its preferentiallycamped cell. When the UE initiates a High Speed Packet Access (HSPA) service, the RNCinstructs the UE to move to an inter-frequency co-coverage neighboring cell through the directedretry or redirection procedure to process the service. This strategy preferentially guaranteesspeech quality for R99 voice services.
Random Camping When random camping is used, UEs in idle mode randomly camp on cells.This strategy maximizes capacity for multi-carrier networks.
2.2 BenefitsDuring special events, this feature balances loads across cells using different frequencies. Inaddition, this feature increases the following items:
l Number of equivalent Erlangs of all the services in the CS domainl Number of High Speed Packet Access (HSPA) bytes transmitted from the Radio Link
Control (RLC) layerl RRC connection setup success rate by 3% to 15% for preferentially camped cells

3 Technical Description
When the cell-level function switch (CAMPING_STRATEGY_SWITCH) and the cell-levellicense switch (CAMPING_STRATEGY_SWITCH) of the Camping Strategy Switch forMass Event feature are turned on in a cell (for example, cell 1), the RNC performs the followingoperations:
1. Filters out cell 1's blind-handover-supporting neighboring cells under the same RNC basedon the value of the BlindHoFlag parameter.
2. Determines whether cell 1 is a preferentially camped cell, compared with its inter-frequencyblind-handover-supporting neighboring cells.
l The following description uses cell 2 as an example, which is an inter-frequency blind-handover-supporting neighboring cell of cell 1. If any of the following conditions is met,the RNC determines that cell 1 is a preferentially camped cell, compared with cell 2:– When the QualMeas parameter is set to CPICH_RSCP, the offset (indicated by
IdleQoffset1sn) of cell 2 from cell 1 is less than or equal to the value of thePrefCampRscpThd parameter.
– When the QualMeas parameter is set to CPICH_ECNO, the offset (indicated byIdleQoffset2sn) of cell 2 from cell 1 is less than or equal to the value of thePrefCampRscpThd parameter.
l The value of the IdleCellBarred parameter is NOT_BARRED for cell 1 and BARRED forcell 2.
3. Periodically checks whether cell 1 meets both of the following conditions within 15minutes:
l The number of RRC connections established is greater than or equal to theRrcConnSumThd parameter value multiplied by 3.
l The ratio of rejected RRC connection setup requests due to power and code resourcecongestion to the total RRC connection setup requests is greater than or equal to the valueof the RrcRejByCongRatioThd parameter.
If any of the preceding conditions is not met, the RNC does not trigger the Camping StrategySwitch for Mass Event feature.
If both of the preceding conditions are met, the RNC determines that there is a sudden sharpincrease in cell 1's traffic and triggers the feature in cell 1. The RNC then includes the followingparameter settings into system information blocks (SIBs) to change the camping strategy appliedto cells 1 and 2 from preferred camping to random camping.

For both cells 1 and 2:
l SIB3: The IdleSintersearch parameter in the ADD UCELLSELRESEL command usesthe value of the same parameter in the SET UCAMPSTRATFORMASS.
l SIB3: The SsearchHCS parameter in the ADD UCELLHCS command uses the value ofthe same parameter in the SET UCAMPSTRATFORMASS command.
l SIB11: The IdleQoffset1sn and IdleQoffset2sn parameters in the ADDUINTERFREQNCELL command use the value 0.
For cell 2 only:
l SIB3: The IdleCellBarred parameter in the ADD UCELLACCESSSTRICT commanduses the value NOT_BARRED. And theIsAccessClass0Barred~IsAccessClass15Barred parameters use the valueNOT_BARRED if they were set to BARRED.
After the RNC includes the preceding parameter settings into SIB3, the Cell camp policyswitching state in heavy traffic domain value is Optimizing for cell 1 and Correlatedoptimizing for cell 2. The domain values are obtained by running the DSP UCELLLCHKcommand.
If cell 1 does not support blind handovers from cell 2 (BlindHoFlag is set to False), the RNCuses the RetryOptSwitch to control whether to configure cell 1 as the target cell for directedretries or redirections from cell 2. If cell 1 supports blind handovers from cell 2(BlindHoFlag is set to True), the RetryOptSwitch does not take effect.
This feature can cause a maximum of seven inter-frequency blind-handover-supportingneighboring cells of cell 1 to enter the Correlated optimizing state. In addition, each of theseneighboring cells can enter this state due to a maximum of three preferentially camped cells.
NOTE
l The RNC only includes the preceding parameter settings into SIB3, and the configuration data of cells1 and 2 actually remains unchanged.
l The RNC will not include the preceding parameter settings into SIB3 for cell 2 if theCELLADMINSTATE parameter of cell 2 is set to HIGHBLKPREP, MEDIUMBLKPREP,LOWBLKPREP, or BLOCK, or if the DSSFlag parameter of cell 2 is set to Configured.
l When this feature is taking effect in a cell, the function of inter-frequency directed retry decision (DRD)for service steering and the function of redirection during the RRC connection release phase fail. Whenthis feature stops taking effect, these functions resume.
4. Restores settings for the preceding parameters and includes restored parameter settings intoSIBs at 4:40 every day to resume the original camping strategy for cells 1 and 2.

5 Network Impact
System CapacityDuring special events, this feature increases the following items:
l Number of equivalent Erlangs of all the services in the CS domainl Number of HSPA bytes transmitted from the RLC layer
Network PerformanceIf there is a sharp increase in a network's traffic mainly due to downlink power resourcecongestion, this feature increases the RRC connection setup success rate by 3% to 15% and theradio access bearer (RAB) setup success rate for preferentially camped cells. The reason is asfollows:
After the congestion occurs, UEs continuously attempt to access the network and as a resultpower consumption increases. After the network camping strategy changes to random camping,the number of continuous access attempts decreases and therefore power consumption isreduced.
If the sharp increase is mainly caused by SF code or (equivalent number of users) ENU resourceinsufficiency, this feature cannot greatly increase the RRC connection setup success rate. Thisis because the number of SF codes and the ENU do not increase after the network campingstrategy changes to random camping.
This feature cannot provide noticeable gains if the capability of a preferentially camped cell isdifferent from that of the corresponding non-preferentially camped cell, for example, apreferentially camped cell supports only R99 services but the corresponding non-preferentiallycamped cell supports HSPA services. The reason is as follows:
The two cells support different types of services. In this case, UE and service allocation betweenthe two cells cannot be balanced.

6 Engineering Guidelines
6.1 When to Use Camping Strategy Switch for Mass EventUse this feature on multi-carrier networks that use preferred camping.
6.2 Network PlanningDo not use this feature on networks where the following conditions are met:
l Macro and micro cells coexist.l Some micro cells use the same frequency as some macro cells.
For example, cell 1 (a macro cell) is a preferentially camped cell, compared with cell 2 (anothermacro cell). In the coverage area of cell 1, a micro cell is deployed. After the network campingstrategy is changed from preferred camping to random camping, blind-handover-based directedretries from cell 2 to cell 1 will fail, resulting in a reduced directed retry success rate.

This results in areduced directedretry success rate.Therefore, do notturn on this switch onsuch a network.
