optimize your GSM network using Ultima Forte Import Modeling Evaluation Optimization Evaluation & Analysis The seven basic steps are: Import the network environment using the IMPORT tool Activate mobile measurements using the MEASUREMENT PLAN module Run the MODELER, based on Mobile Statistics Evaluate the current Frequency Plan using EVALUATOR Run the NEIGHBOR OPTIMIZER to generate a new Neighbor List Run the FREQUENCY OPTIMIZER to generate a new Frequency plan EVALUATE the new Frequency Plan, and compare it to the Baseline March 11 Schema Proprietary and Confidential of 109 Ultima Forte – Seven Basic Steps to Optimize an Alcatel Network Create Your Environment Using Importer 2.1 Organizing Network Configuration Data on Your Computer The project folder could be created anywhere in the C: drive For easier access, place it under \My Documents Create a Project folder (e.g., New York Project) with a DB folder, an MS folder, and an HO folder 2.1.1 Project Folder The Project folder should contain:  DB folder (Section ‎2.1.2)  MS folder (Section ‎2.1.3)  HO folder (Section ‎2.1.4) 2.1.2 DB Folder Currently, Alcatel Versions BR7, BR8, and BR9 are supported by Ultima Forte (Release 4.1 and later versions) The DB folder should contain:  Network configuration dumps  A coordinates file, with the lat/long and azimuth of all cells The two optional columns, LAC and CI, are used to match sector information Additional ―Keywords‖ columns can be added to import user-defined Keywords Be sure the names of the sectors in the Coordinate file match the names in the switch dumps If the names not match, add columns LAC and CI to match sector information 2.1.3 MS Folder The MS folder should contain sub-folders that include the dates when data was collected Each folder should have:  Mobile Statistics data and RxQual data  Binary PMRES-31 files  Network configuration dumps that correspond to each date March 11 Schema Proprietary and Confidential 10 of 109 Ultima Forte – Seven Basic Steps to Optimize an Alcatel Network G.1.8 Evaluator Figure 97: Network Properties Advanced Tab – Evaluator Group The Evaluator group contains the following fields, which relate to the number of iterations that the Evaluator runs: CONVERGENCE_ACCURACY_RATIO is the accuracy ratio to consider when the Evaluator Monte-Carlo algorithm has converged, meaning that 90% of the cells have reached a 5% accuracy ratio within fewer than 500 iterations CONVERGENCE_PERCENTAGE_OF_NETWORK_ELEMENTS (%) is the percentage of network elements (Sectors, sub-cells or channel group, depending on the settings specified in Step1 of the Evaluator) needed to consider when the Evaluator Monte-Carlo algorithm has converged as defined by the CONVERGENCE_ACCURACY_RATIO NUMBER_OF_ITERATIONS is the maximum number of iterations allowed SECTORS_TO_DISPLAY_IN_REPORT is the Number of sectors to display in the Quality Delta Analysis report March 11 Schema Proprietary and Confidential 95 of 109 Ultima Forte – Seven Basic Steps to Optimize an Alcatel Network G.1.9 RF Features Figure 98: Network Properties Advanced Tab - RF Features Group The RF features group contains the following fields: The HALF_RATE_AMR_ACTIVATION_THRESHOLD (dB) is a C/I threshold used to switch a call from AMR FR to AMR HR during Evaluator iterations For any C/I value above that threshold, AMR HR will be considered to be based on traffic loading IUO_ACTIVATION_THRESHOLD is the C/I threshold used to activate the Nokia Intelligent Underlay Overlay (IUO) feature, supported by Forte This advanced feature enables the use of TCH channels from neighboring sectors when no deterioration in performance is expected The feature is automatically detected by the Forte Importer when the network environment is imported from the Nokia OSS The IUO prefix is automatically added to the channel group name with this feature, and imported into Forte An IUO channel group is recognized and accounted for by the Evaluation process The VOICE_ACTIVITY_FACTOR (%) is the default used when discontinuous transmission (DTX) is active on a cell March 11 Schema Proprietary and Confidential 96 of 109 Ultima Forte – Seven Basic Steps to Optimize an Alcatel Network G.1.10 Frequency Plan Optimizer Figure 99: Network Properties Advanced Tab – Frequency Plan Optimizer Group The Frequency Plan Optimizer group contains the following fields: The HANDOVER_ADJ_IMPACT (%) percentage is used in Step of the OFP process, when handover logical constraints are selected to weigh the impact of adjacent frequencies between two neighboring cells If the value of HANDOVER CONSTRAINTS LIST CALCULATION is set to Handover Statistics, handover constraints in the OFP are weighed on the basis of the number of handover attempts made If the value is set to fixed, handover attempts are not considered The HANDOVER_CO_IMPACT (%) is used in Step of the OFP process, when Handover Logical Constraints is selected in weighing the impact of co-channel frequency between two neighboring cells March 11 Schema Proprietary and Confidential 97 of 109 Ultima Forte – Seven Basic Steps to Optimize an Alcatel Network The HIGH_OPTIMIZATION_PRIORITY_GUARD is used to increase the C/I parameter Co– Channel_C2I_Threshold (e.g., increasing it from 12 to 9, based on a default offset value), defined in the Modeler section for High Priority cells, as defined in the Sector Channel group properties IGNORE_EGSM_DEFINITIONS is used either to ignore or to apply EGSM sub-band definitions; this parameter is only relevant for 900MHz bands, and the default is Yes (to ignore definitions) The LOW_OPTIMICATION_PRIORITY_GUARD is used to lower the C/I parameter Co– Channel_C2I_Threshold (for example by lowering it from 12 to 15, based on a default offset value) defined in the Modeler section for Low Priority cells, as defined in the Sector Channel group properties The MAX _DISTANCE_FOR_BCCH_BSIC_REUSES (Km) setting displays only the BCCHBSIC reuses below a certain distance (preset to 30 Km) in the BCCH-BSIC reuses report The MAX _DISTANCE_FOR_BCCH _REUSES (Km) setting displays only the BCCH reuses below a certain distance (preset to Km) in the BCCH-BSIC reuses report The MINIMIZE_CHANGES_HIGH (%) sets a percentage of frequency changes allowed when the Minimum Changes option in Step of the OFP is set to High 10 The MINIMIZE_CHANGES_LOW (%) sets a percentage of frequency changes allowed when the Minimum Changes option in Step of the OFP is set to Low 11 The MINIMUM_CHANGES_MEDIUM (%) sets a percentage of frequency changes allowed when the Minimum Changes option in Step of the OFP is set to Medium 12 MIN_CARRIED_TRAFFIC_PER_TRX allows users to define a minimum traffic threshold value for each TRX This value overrides any actual TRX value that falls below the threshold This makes it possible for users to compensate sectors and TRXs with low traffic levels 13 PLAN_HSN_FOR_BASE_BAND plans HSN for baseband channel groups Version 4.1 supports HSN optimization for baseband hopping schemes (by changing the value to Yes) 14 PLAN_MAL_PER_CHANNEL_GROUP plans a separate MAL, HSN, and MAIO allocation for each SFH channel group 15 The TRIANGULATION_ADJ_IMPACT (%) percentage is used in Step of the OFP process, when Triangulation Logical Constraints is selected, to weigh the impact of adjacent frequencies between second-tier neighbors 16 The TRIANGULATION_CO_IMPACT (%) percentage is used in Step of the OFP process, when the Triangulation Logical Constraints is selected, to weigh the impact of cofrequencies between second-tier neighbors March 11 Schema Proprietary and Confidential 98 of 109 Ultima Forte – Seven Basic Steps to Optimize an Alcatel Network G.1.11 Statistics Figure 100: Network Properties Advanced Tab - Statistics Group The Statistics group contains the following fields: The BAD_QUALITY_FER (%) percentage threshold is used to classify traffic as being affected by bad FER in the Evaluator The BAD_QUALITY_RXQUAL threshold is used to classify traffic as being affected by bad Rxqual in the Evaluator March 11 Schema Proprietary and Confidential 99 of 109 Ultima Forte – Seven Basic Steps to Optimize an Alcatel Network G.1.12 Maps and Google Earth Display Figure 101: Network Properties Advanced Tab – Maps and Google Earth Display The Maps and Google Earth Display
