The following two types of reserved parameters or bits are advanced parameters or bits: 1. Reserved parameters or bits that have significant impacts on network performance once their values are slightly changed. This type of reserved parameters or bits are not used in features. 2. Reserved parameters or bits whose functions can be maximized only when they work in certain portfolios. For this type of parameters or bits, changing the value of only one reserved parameter or bit has little effect and may cause accidents or bring a negative impact to the network. To set an advanced parameter or bit, contact Huawei Customer Service Center for technical support.GUI Value RangeValue range of the reserved parameter or bit displayed on the GUIUnitUnit of the GUI value for the reserved parameter or bitActual Value RangeActual value that corresponds to the GUI value of the reserved parameter or bitDefault ValueInitial value assigned by the system to the parameter. For a bit field parameter, ON indicates that the bit representing the sub-parameter is set to 1, OFF indicates that the bit representing the sub-parameter is set to 0. The default value is not displayed on the configuration window of a SET command.Recommended ValueRecommended value of the reserved parameter or bit in a specific application scenario. The recommended value can be the same as the default value.CautionCautions to be taken during the modification.Impact on Radio Network PerformanceImpact of the parameter on radio network performance when the reserved parameter or bit is set to different valuesIntroduced in VersionProduct version in which a reserved parameter or bit is first used. For example: Patch release for an R version: VX00R0XXCXXSPHXXX Patch releases for different R versions: VX00R0XXCXXSPHXXX and VX00R0XX'CXXSPHXXX Patch release and baseline version for different R versions: VX00R0XXCXXSPHXXX and VX00R0XX'

VX00R0XXCXXSPHXXX indicates a patch release for an R version. A reserved parameter or bit that is first used in this patch release will be used in all later patch releases.

VX00R0XX' indicates a baseline version for an R version. A reserved parameter or bit that is first used in this baseline version will be used in all later baseline versions and patch releases.Change ReasonReason why the reserved parameter or bit is used and the reserved parameter or bit in an earlier version inherited by that in the current versionDisuse StatementMechanism that the system uses to process the value of a reserved parameter or bit set by operators after the reserved parameter or bit is out of useDisuse VersionBaseline version in which a reserved parameter or bit is out of useIntroduction to Reserved ParametersThis section describes the definition of reserved parameters, the purpose of using reserved parameters, the status of reserved parameters, and disuse mechanism.DefinitionReserved parameters are parameters reserved for use in patch releases. When such parameters are being added, they can be set but have no functional behaviors. A reserved parameter has functional behavior only when it is used in a patch release. Reserved parameters are used to fix bugs, solve network compatibility issues, or implement network element interconnection.Purpose Avoiding impacts on southbound and northbound interfaces Avoiding service interruption caused by patch installationStatusThe state of a reserved parameter can be:Unused: indicates that the reserved parameter has not been used. In-use: indicates that the reserved parameter is being used.Disused: indicates that the function of the reserved parameter has been implemented by a new parameter (the ID of the new parameter reflects the function) or the function of the reserved parameter has been removed.Disuse MechanismA reserved parameter that is used in a patch release for an R version will fall into disuse in N+1 version. After the disuse, the reserved parameter is not used in the R version any more. Disuse mechanism: 1. A new parameter has been used to replace the reserved parameter. The ID of the new parameter reflects the function. 2. The function configured through the reserved parameter has been deleted or does not need to be set manually.

The algorithm does not take effect.1: This switch is turned on. The algorithm takes effect. Operations of the algorithm: Access mode : The algorithm also considers coverage and loads to determine whether the downlink SRBs can be carried on the HS-DSCH when a UE transits from the idle, CELL_FACH, CELL_PCH, or URA_PCH state to the CELL_DCH state during an RRC connection setup, RAB setup, or RAB modification or when a CELL_DCH UE experiences an incoming inter-RAT handover or an incoming combined hard handover and SRNS relocation. Connected mode After a UE accesses a cell, the algorithm determines whether to deliver periodic RSCP and Ec/N0 measurement control messages. When the RNC receives periodic measurement reports on the RSCP and Ec/N0, the algorithm determines whether to initiate the SRB reconfiguration process.

If the load of the best cell is in this state or a lighter state, the cell is in a light load state. Otherwise, the cell is in a heavy load state. Actual value: GUI value 1Mappings between the actual value and downlink non-HSPA power load status are as follows: Actual value 0 maps to DL_LIGHT_STATE(light state)Actual value 1 maps to DL_NORMAL_STATE(normal state)Actual value 2 maps to DL_LOADED_STATE(loaded state)Actual value 3 maps to DL_HEAVY_STATE(heavy state)Actual value 4 maps to DL_OVERRLOAD_STATE(overload state) If the value of this parameter is beyond the value range, set it to 3, which corresponds to the actual value 2.

The downlink non-HSPA power load can be in either of the following states: light state (DL_LIGHT_STATE), normal state (DL_NORMAL_STATE), loaded state (DL_LOADED_STATE), heavy state (DL_HEAVY_STATE), and overload state (DL_OVERRLOAD_STATE).The downlink non-HSPA power load state transition process is as follows: If the downlink non-HSPA power load in the light state is larger than 30%+10%, transition from light state to normal state is triggered. If the downlink non-HSPA power load in the normal state is smaller than 30%-10%, transition from normal state to light state is triggered; if the downlink non-HSPA power load in the normal state is larger than 50%+10%, transition from normal state to loaded state is triggered. If the downlink non-HSPA power load in the loaded state is smaller than 50%-10%, transition from loaded state to normal state is triggered; if the downlink non-HSPA power load in the loaded state is larger than 50%+10%, transition from loaded state to heavy state is triggered. If the downlink non-HSPA power load in the heavy state is smaller than 70%-10%, transition from heavy state to loaded state is triggered; if the downlink non-HSPA power load in the overload state is smaller than 95%-10%, transition from overload state to heavy state is triggered.

The downlink non-HSPA power load is as follows: Downlink load in an HSDPA cell is the proportion of non-HSPA power consumption to the maximum transmit power of this cell MaxTxPower; Downlink load in an R99 cell is the proportion of TCP to the maximum transmit power of this cell.1~5None0~403NoneIf the coverage- and load-based algorithm for dynamic reconfiguration of the channel mapped to downlink SRBs takes effect, the downlink SRBs of UEs in heavily loaded cells are preferentially carried over HS-DSCH.
