2.1 Basic Knowledge of OSS Management This section describes the basic knowledge about the Operations System (OSS) management functions. You should grasp the basic knowledge before performing management operations. In the OSS management, objects represent the physical or logical entities on the network. A physical or logical entity, namely, an object, can be an OSS or an NE. l

Operations System The operations system (OSS) defines network management devices that can be connected with the DAMS. The DAMS collects the required data from a specified FTP server according to the relevant attributes set in the OSS and saves the data as files in a specified path on the DAMS server.

l

NE NEs are used to identify network devices, such as BTS and BSC.NEs can be classified into physical NEs and virtual NEs. – –

The OSS management subsystem provides the basic functions for managing objects. The subsystems such as centralized task management add objects to the GUI through the OSS management subsystem. The OSS management of the DAMS enables you to create and delete OSSs, view and modify OSS attributes, and manage the information about NEs managed by the OSS.

2.2 Creating OSSs and the Managed NEs This section describes how to create OSSs. You can create an OSS to initialize the protocol of the interface between the Nastar and the EMS device so that the Nastar accesses the EMS device through the interface to obtain the required data. In addition, you can set NEs managed by the OSS so that the Nastar collects required data from the selected NEs.

UMTS Coverage Analysis

About This Chapter The UMTS coverage analysis function enables you to obtain UMTS coverage analysis data, create UMTS coverage analysis tasks, query UMTS coverage analysis results, and export UMTS coverage analysis reports from the Nastar. The Nastar analyzes the measurement reports (MRs) sent by UEs and displays the coverage status, signal quality, and subscriber distribution of a measurement cell. This function helps to locate wireless network problems such as weak coverage, cross coverage, and poor service quality. 4.1 Basic Knowledge of UMTS Coverage Analysis This section describes the basic knowledge of UMTS coverage analysis. The Nastar performs UMTS coverage analysis based on the measurement reports (MRs) reported by UEs and then generates analysis results. These analysis results help s learn the coverage of measurement cells and identify problems such as weak coverage, cross coverage, and poor service quality. 4.2 UMTS Coverage Analysis Process This section describes the UMTS coverage analysis process. 4.3 Obtaining UMTS Coverage Analysis Data This section describes how to enable the Nastar to obtain UMTS coverage analysis data.

The Nastar performs UMTS coverage analysis based on the measurement reports (MRs) reported by UEs and then generates analysis results. These analysis results help s learn the coverage of measurement cells and identify problems such as weak coverage, cross coverage, and poor service quality. An MR reported by a UE contains downlink RS, Ec/No, and transmit propagation delay (TP). After the conditions for coverage analysis are set, the Nastar analyzes the coverage of the selected cell and then displays analysis results in a two-dimensional (2-D) chart, a three-dimensional (3D) chart, and a table. l

In the 2-D chart, information about the following services is displayed: AMR, VP, BE, AMR+BE, and OTHER services. Information about each service contains three counters, namely, RS_DL, Ec/No_DL, and TP.

l

In the 3-D chart, information about CS services and PS services is displayed. Information about both CS services and PS services contains three counters, namely, RS_DL, Ec/ No_DL, and TP.

l

In the overview table, the counter statistics of all services involved in the 2-D chart are displayed.

The results of coverage analysis can be exported as .csv files. s can optimize cells with coverage problems according to the exported analysis results.

The MRs can reflect the actual propagation of radio signals. By displaying required information, the Nastar helps s solve problems caused by missing or redundant neighboring cell configuration or improper setting of neighboring cell priorities.

Neighboring Cell Analysis Proper neighboring relations ensure that a UE at the border of a cell initiates a handover in a timely manner. In this case, handover gain is obtained, and interference inside the network is reduced. Furthermore, the quality of network services is improved, and network performance is stable. Based on configuration data and engineering parameters, the Nastar performs intra-frequency neighboring cell analysis for the selected measurement cell according to the MRs and events reported by UEs. Based on obtained measurement data, the Nastar determines missing and redundant neighboring cells, identifies neighboring cells whose priorities need to be adjusted, and provides suggestions on adjusting neighboring cell priorities. According to the suggestions provided by the Nastar, you can compare the suggested neighboring cell priorities and actual neighboring cell priorities and then adjust the priorities of some neighboring cells accordingly. Analysis results are displayed in a line chart or a bar chart. Different types of neighboring cells and final ranking of neighboring cell priorities are displayed in different colors in the chart. You can export the results of the neighboring cell analysis as a .csv, .xls, or .xlsx file, which helps to optimize the neighboring relations on the network. Issue 02 (2010-12-30)

5 UMTS Intra-Frequency Neighboring Cell Analysis

Nastar Network Optimization Guide (UMTS)

Some cells may share the same frequency and same primary scrambling code (PSC) with the dominant cell. Therefore, the Nastar first identifies possible neighboring cells from undefined neighboring cells in the measurement results by UARFCNs and PSCs and then predicts the signal strength based on cell information including site location, antenna azimuth, and antenna gain. After identifying possible neighboring cells, the Nastar generates analysis reports about possible neighboring cells. In addition, the Nastar can display UMTS neighboring cell analysis results and possible neighboring cell analysis results on maps and highlight test cells, missing neighboring cells, redundant neighboring cells, defined and undefined neighboring cells in different colors. This function helps s query neighboring relationships.

Limitation and Impact The following factors may affect the accuracy of neighboring cell analysis results: l

Accuracy of engineering parameters

l

Stability of networks in some aspects including setting of air interface parameters and network topology, during the collection of UMTS neighboring cell analysis data Table 5-1 describes the network changes and their impacts.

Table 5-1 Network changes and their impacts Network Change

Impact

Addition or deletion of BTSs

Affects the network coverage and handovers between cells. In this case, analysis results cannot accurately reflect the current network status.

Change of antenna data, such as azimuth, tilt angle, or height

Results in changes of cell coverage and network interference.

Change of handover relations and parameters

Affects the statistical results during the period of collecting the data about neighboring relations and the period of optimizing neighboring relations.

Change of RNC topology or other NE topology

The RNC is responsible for collecting statistical results. Therefore, a measurement task cannot be performed properly if the network topology is changed. You are advised to keep the network topology unchanged during data collection.

NOTE

The Nastar can measure and analyze UMTS intra-frequency neighboring cells only during soft handovers or softer handovers.

Nastar Network Optimization Guide (UMTS)

5 UMTS Intra-Frequency Neighboring Cell Analysis

Neighboring cell analysis algorithms are used to check missing and redundant neighboring cells and to provide suggested priorities of neighboring cells. l

The algorithm for providing suggested priorities of neighboring cells is as follows: 1.

Calculate the overall score of each neighboring cell. The Nastar calculates the overall score of a neighboring cell according to the algorithm by considering the factors such as the number of times the neighboring cell occurs, relative difference value between the Ec/Io of the neighboring cell and the Ec/Io of the dominant cell, and absolute difference value between the Ec/Io of the neighboring cell and the Ec/Io of the dominant cell.

2.

Neighboring cells are ranked in descending order based on their overall scores. The priorities of the neighboring cells are directly proportional to their overall scores. The highest suggested priority for a neighboring cell is 0.

l

The algorithm for checking missing neighboring cells is as follows: If the suggested priority of an undefined neighboring cell is smaller than the number of suggested neighboring cells, this undefined neighboring cell is considered as a missing neighboring cell and needs to be configured according to the suggestion.

l

The algorithm for checking redundant neighboring cells is as follows: If the suggested priority of a defined neighboring cell is equal to or greater than the number of suggested neighboring cells, this defined neighboring cell is considered as a redundant neighboring cell and needs to be deleted according to the suggestion.

5.2 UMTS Intra-Frequency Neighboring Cell Analysis Process This section describes the UMTS intra-frequency neighboring cell analysis process. Figure 5-1 shows the process of UMTS intra-frequency neighboring cell analysis.

The basic knowledge helps you perform the operations related to UMTS/GSM neighboring cell analysis. 6.1.1 UMTS/GSM Neighboring Cell Analysis Function This section describes the UMTS/GSM neighboring cell analysis function. This function is used to analyze defined and undefined GSM neighboring cells of UMTS cells. Based on the analysis results, you can check and handle problems caused by redundant or missing neighboring cell configuration. This function enables the Nastar directly displays the required information, helping you solve network quality problems that are caused by the redundant or missing neighboring cell configuration. 6.1.2 Algorithms for UMTS/GSM Neighboring Cell Analysis This section describes the algorithms for UMTS/GSM neighboring cell analysis, such as the algorithms used to check missing and redundant neighboring cells.

6.1.1 UMTS/GSM Neighboring Cell Analysis Function This section describes the UMTS/GSM neighboring cell analysis function. This function is used to analyze defined and undefined GSM neighboring cells of UMTS cells. Based on the analysis results, you can check and handle problems caused by redundant or missing neighboring cell configuration. This function enables the Nastar directly displays the required information, helping you solve network quality problems that are caused by the redundant or missing neighboring cell configuration.

Inter-RAT Neighboring Cell Analysis After you set the conditions for checking the redundant or missing neighboring cell configurations, the Nastar performs inter-RAT neighboring cell analysis for the selected cell. The analysis results are displayed in a bar chart. In the bar chart, the defined GSM neighboring cells, undefined GSM neighboring cells, redundant GSM neighboring cells, and missing GSM neighboring cells are illustrated in different colors. The Nastar can export analysis results of inter-RAT neighboring cells to a file. In the inter-RAT neighboring cell analysis result window, you can export the result file of inter-RAT neighboring cell analysis after adding the missing neighboring cells and deleting the redundant neighboring cells. The result file provides the related optimization suggestions. You can export the results of the inter-RAT neighboring cell analysis as a .csv, .xls, or .xlsx file, which helps to optimize the neighboring relations on the network.

Requirements for the Network The network must be stable during the period when neighboring cell data is collected. Otherwise, the analysis results may be inaccurate. Table 6-1 describes the network changes and their impacts. Issue 02 (2010-12-30)

Table 6-1 Network changes and their impacts Network Change

Impact

Addition or deletion of BTSs

Affects the network coverage and handovers between cells. In this case, analysis results cannot accurately reflect the current network status.

Change of antenna data, such as azimuth, tilt angle, or height

Results in changes of cell coverage and network interference.

Change of handover relations and parameters

Affects the statistical results during the period of collecting the data about neighboring relations and the period of optimizing neighboring relations.

Change of RNC topology or other NE topology

The RNC is responsible for collecting statistical results. Therefore, a measurement task cannot be performed properly if the network topology is changed. You are advised to keep the network topology unchanged during data collection.

6.1.2 Algorithms for UMTS/GSM Neighboring Cell Analysis This section describes the algorithms for UMTS/GSM neighboring cell analysis, such as the algorithms used to check missing and redundant neighboring cells. Based on the information reported by UEs such as the signal level of a cell, the Nastar calculates the overall scores and then sorts defined and undefined GSM neighboring cells. According to the sequence of GSM neighboring cells and result analysis chart, s can analyze the neighboring cells depending on the actual network situation, and then provide suggestions on the missing GSM neighboring cell configuration and redundant GSM neighboring cells to be deleted. The algorithm for the UMTS/GSM neighboring cell analysis is as follows: 1.

Calculate the overall scores of all the GSM neighboring cells of the measurement cell. The sequence of GSM neighboring cells is arranged on the basis of the strength of receive level. That is, the stronger the signal level is, the smaller the sequence number of the GSM neighboring cell and the higher the score is. The score is set during the creation of a UMTS/ GSM neighboring cell analysis task.

2.

Determine missing neighboring cells. When the sequence number of an undefined GSM neighboring cell is smaller than or equal to Neighboring Cell Count Setting that is set when a UMTS/GSM neighboring cell analysis task is created, the GSM neighboring cell is regarded as a missing neighboring cell.

3.

Determine redundant neighboring cells. When the sequence number of a defined GSM neighboring cell is larger than Neighboring Cell Count Setting that is set when creating a UMTS/GSM neighboring cell analysis task, the GSM neighboring cell is regarded as a redundant neighboring cell.

UMTS Pilot Pollution Analysis

About This Chapter The UMTS pilot pollution analysis function enables you to obtain UMTS pilot pollution analysis data, create UMTS pilot pollution analysis tasks, query UMTS pilot pollution analysis results, and export UMTS pilot pollution analysis reports from the Nastar. By analyzing subscriber calls, the Nastar identifies cells where pilot pollution exists, cells that cause interference, and severity of cell pollution. The Nastar also displays the analysis results on a map so that you can learn the detailed situation of pilot pollution. This function reduces the drive test (DT) time and improves the accuracy of problem location. 7.1 Basic Knowledge of UMTS Pilot Pollution Analysis The UMTS pilot pollution analysis function enables you to analyze routine calls. By analyzing query reports, the Nastar identifies cells where pilot pollution exists, cells that cause interference, and severity of cell pollution and displays the analysis results on a map. In this manner, you can directly learn the details about pilot pollution. 7.2 UMTS Pilot Pollution Analysis Process This section describes the UMTS pilot pollution analysis process. 7.3 Obtaining UMTS Pilot Pollution Analysis Data This section describes how to enable the Nastar to obtain UMTS pilot pollution analysis data.

7 UMTS Pilot Pollution Analysis

7.1 Basic Knowledge of UMTS Pilot Pollution Analysis The UMTS pilot pollution analysis function enables you to analyze routine calls. By analyzing query reports, the Nastar identifies cells where pilot pollution exists, cells that cause interference, and severity of cell pollution and displays the analysis results on a map. In this manner, you can directly learn the details about pilot pollution. Pilot pollution refers to the situation that there are excessive signals with close strength in an area in a network using code division multiple access (CDMA) technology. Generally, excessive radio signals form a cross coverage to the neighboring cells due to improper site layout or impacts of geographical locations. In this case, pilot pollution is produced. The pilot pollution affects network performance in the following aspects: l

Reduced call connection ratio When there is pilot pollution, the UE constantly performs cell reselection because it cannot stably camp on a cell. During a call, the UE constantly changes serving cells, leading to call failure easily.

l

Increased call drop rate When there is pilot pollution, ping-pong hangovers occur frequently during a call because the pilot is not strong enough to be the dominant pilot. As a result, the call drop rate increases.

l

Reduced system capacity Pilot pollution causes strong interference. Hence, the receive sensitivity of the system is improved, and thus signals far away from the NodeB cannot be received. As a result, the system capacity is reduced.

l

High Block Error Rate (BLER) When there is pilot pollution, there is strong interference. Hence, the BLER is increased, leading to the deterioration of the voice quality and the decrease in the data transmission rate.

Severe pilot pollution may cause problems such as call drops, deteriorated voice quality, reduced system capacity, and network interference. Based on routine calls, the Nastar analyzes the pilot pollution, thus helping in locating polluted cells and polluter cells. Used with the GIS, this function enables the Nastar to display polluted cells and polluter cells in geographic mode, thus improving the efficiency of problem analysis and location.

7.2 UMTS Pilot Pollution Analysis Process This section describes the UMTS pilot pollution analysis process. Figure 7-1 shows the process of UMTS pilot pollution analysis.

7.3.2 Creating a Data Import Task This section describes how to create a data import task. The Nastar periodically imports the analysis data such as the performance data, VIP analysis data, and cell performance analysis data on the Nastar server into the database to perform various theme analysis tasks.

Prerequisite You have logged in to the Nastar client.

Context l

A data import task is a -defined scheduled task. You can create only one -defined scheduled task of the same type.

l

The data import task can only be executed periodically. The unit of the task execution period can be Hour, Day, Week, or Month. The data import task of the same type can only be created once on the Nastar. After the task is created, the Nastar automatically imports data at the preset time.

l

A data import task can be performed only after the related data collection task is complete (if the data collection task running type is period, only after the first period). Otherwise, the integrity of the imported data may be affected.

l

You need to create data import tasks of different types based on the type of an analysis task. Table 7-3 shows the mapping between analysis task types and types of data import tasks. Table 7-3 Mapping Between Analysis Task Types and Types of Data Import Tasks

8 UMTS Uplink Interference Analysis

UMTS Uplink Interference Analysis

About This Chapter The UMTS uplink interference analysis function enables you to obtain UMTS uplink interference analysis data, create UMTS uplink interference analysis tasks, and query UMTS uplink interference analysis reports. With the uplink interference analysis function, the Nastar analyzes Received Total Wideband Power(RTWP) data reported by NodeBs and preliminarily locates NodeBs that are affected by interference by ranking NodeBs based on their interference.

8.1 Basic Knowledge of UMTS Uplink Interference Analysis This section describes the basic knowledge of UMTS uplink interference analysis. With this function, the Nastar analyzes Received Total Wideband Power (RTWP) data reported by the NodeBs and generates analysis results for identifying interference on the network. In addition, the Nastar analyzes the signal strength of the main and diversity antennas on the uplink, helping s locate antenna problems. Uplink interference has an impact on network quality. If uplink interference exists, the call quality, network coverage, and network capacity may be greatly affected, and call drops, handover problems, and congestion may occur frequently. If interference and load are not clearly identified, load control cannot be performed properly. With the uplink interference analysis function, the Nastar analyzes RTWP data reported by NodeBs and preliminarily locates NodeBs that are affected by interference by ranking NodeBs based on their interference. Then, you can view the charts showing the overall RTWP trends of the selected cells to determine whether the average interference intensity of main and diversity antennas is proper and judge the interference characteristics. You can also view the distribution chart of main and diversity difference to determine whether the main and diversity antennas are connected correctly. After the conditions for uplink interference analysis are set, the Nastar performs uplink interference analysis on the selected cells. The analysis results are displayed in a line chart. The signal strength of the main and diversity antennas at each time point and the overall change trends are displayed in different colors in the chart.

Nastar Network Optimization Guide (UMTS)

9 UMTS VIP Analysis

9.1 Basic Knowledge of UMTS VIP Analysis The UMTS VIP analysis function enables you to routinely monitor the calls of the selected VIP subscribers on the network. By analyzing monitoring reports, you can learn the service quality experienced by VIP subscribers. This helps network engineers identify and solve potential network problems in advance, hence improving VIP subscriber satisfaction.

VIP Analysis The Nastar obtains the information about IMSIs reported by UEs during calls and finally helps to solve the problems related to the subscriber-level network optimization through the aggregation and analysis of KPIs (including network-level KPIs, service-level KPIs in CS and PS domains, and KPIs of active cells) based on the VIP group level and VIP subscriber level. l

Aggregation and analysis of KPIs by VIP group enable you to monitor the subscribers in important groups in a centralized, convenient, and timely manner, hence improving operation efficiency and reducing operation expenditure. In addition, this enables you to identify problem VIP groups and problem VIP subscribers so that you can analyze and solve the problems in advance to avoid losing the VIP subscribers.

l

The aggregation and analysis of KPIs based on the VIP subscriber level provide a detailed analysis of KPI trends related to subscriber experience and behavior. For example, analysis of variation trends based on voice service setup delay, analysis of variation trends based on SQI distribution of voice service quality, analysis of variation trends based on data service average rate, analysis of variation trends based on uplink BLER distribution of data services, and analysis of variation trends based on service duration. In this manner, you can quickly identify the VIPs with the worst and best service quality during a certain period and learn about the time when network problems occur.

The Nastar also provides an in-depth analysis for the VIP subscribers whose raw data is collected in advance. If you find that the KPIs of some VIP subscribers in a group deteriorate but cannot identify the problem on site, the Nastar helps you retrieve the detailed call reports of these VIP subscribers within a specified period. By analyzing these reports, the network engineers can quickly locate the key call report that results in the deterioration of KPIs, and then analyzes the information such as the network quality and signaling procedure before the link release and exception causes, hence locating problems. Aggregation and analysis of KPIs of active cells by VIP group and VIP subscriber help network engineers learn the main active areas of VIP subscribers on the network. Based on the network problems that occur in these active cells, the network engineers can quickly identify the key cells that need to be preferentially concerned to solve these network problems. In this manner, you can solve the problem of QoS deterioration of VIP subscribers caused by network problems in time. Along with geographic information system (GIS), this function enables the Nastar to display active cells geographically, hence improving the efficiency in analyzing and locating problems.

Limitations The UMTS VIP analysis function allows the NEs to report raw call data of important VIP subscribers to the Nastar. The amount of raw data is huge. Therefore, limitations are required to prevent the system from becoming overloaded in the case of concurrent operations by a large number of s. In the case of analysis by VIP group, the Nastar allows the analysis of 30,000 VIP subscribers (that is, the number of VIP subscribers in all the VIP groups that are selected Issue 02 (2010-12-30)

for the analysis cannot exceed 30,000). In the case of analysis by VIP subscribers, the Nastar allows the analysis of 2,000 VIP subscribers (that is, the number of VIP subscribers in all the VIP groups that are allowed to report raw data cannot exceed 2,000). In the analysis of the KPIs relevant to the active cell of the VIP subscribers, the geographical distribution of active cells needs to be displayed. You must import correct engineering parameters to ensure the display effect.

10.1 Basic Knowledge of UMTS Complaint Analysis This section describes the basic knowledge of UMTS complaint analysis . The Nastar can perform UMTS complaint analysis based on the call records before and after some complaints in the UMTS network. This function helps you locate and solve complaint problems, improves the efficiency of solving problems, and improves subscriber satisfaction.

Complaint Analysis The Nastar obtains the call event records of complaint subscribers, and then filters, aggregates, and analyzes data based on a specified history period and detailed call records of subscribers in a specified area, assisting in locating and solving problems. The complaint analysis consists of the aggregation and analysis of cause types in call reports of complaint subscribers, aggregation and analysis of information about call reports of complaint subscribers, analysis of detailed information about call reports of complaint subscribers, analysis of procedure before signaling release in call reports of complaint subscribers, and analysis of active cells in call reports of complaint subscribers. l

The aggregation and analysis of cause types in call reports of complaint subscribers help network engineers filter and aggregate call reports based on exception causes. Cause types are classified into five types: non-exception, access failed, handover failed, abnormal call release, and other exceptions. For details about cause types, see Table 10-1. Table 10-1 Cause type and related description Cause Type

Description

Call Status

Non-exception

The aggregation and analysis of call information of complaint subscribers provide the overview of information about all the filtered call records. The information includes the access time, access cell, release time, release cell, IMSI, IMEI, service duration, link setup type, and call status. This function helps network engineers quickly identify abnormal call records (for example, too-short-time call record) and preliminarily learn the situation of complaint subscribers.

l

The analysis of detailed call records of complaint subscribers provides the detailed information about all the filtered call records. The information includes the subscriber information, access/release information, CS service information, PS service information, and handover information. This function helps network engineers learn the key events that occur during calls, service usage, and MRs before the signaling release, thus accurately and quickly assisting in problem location.

l

The analysis of procedure before signaling release in call reports of complaint subscribers provides the detailed procedure before signaling release of all the filtered subscribers. This function helps network engineers locate problems based on the information before signaling release.

Limitations The GSM complaint analysis function requires raw call records of complaint subscribers. The amount of raw data is huge. Therefore, if IMSI is used to identify complaint subscribers, the maximum number of complaint subscribers selected in a complaint analysis task cannot exceed 2,000; if peer MSISDN is used to identify complaint subscribers, the maximum number of complaint subscribers selected in a complaint analysis task cannot exceed 200. The selected complaint subscribers must be under the same OSS.

Nastar Network Optimization Guide (UMTS)

10 UMTS Complaint Analysis

NOTE

The maximum number of complaint subscribers selected in a complaint analysis task is different when IMSI or peer MSISDN is used to identify complaint subscribers. The causes are as follows: A subscriber call record contains the IMSI of the calling party and the peer MSISDN. The format of IMSI is fixed and unique; whereas the peer MSISDN can be a mobile phone number, fixed-line phone number, or hotline and the MSISDN combination is different in each country. To ensure that all call records of complaint subscribers can be obtained when the peer MSISDN is used to identify complaint subscribers, the Nastar allows s to perform fuzzy search. That is, after s type keywords, all call records whose peer MSISDN field contains keywords can be obtained. In this manner, the integrity of analysis data is ensured, but the obtained call records are several times of those queried by IMSI. Therefore, the maximum number of complaint subscribers selected in a complaint analysis task when the peer MSISDN is used to identify complaint subscribers is smaller than that in the case when IMSI is used to identify complaint subscribers.

10.8 How Do I Solve the Problem That Hard Handover Information, Soft Handover Information, and Signaling Procedure Before Call Release Are Empty in the Results of UMTS Complaint Analysis Tasks This section describes the cause of the problem that hard handover information, soft handover information, and signaling procedure before call release are empty in the results of UMTS complaint analysis tasks and describes how to solve this problem.

Symptom After the data obtained from an RNC in V900R012C01SPC300 or a later version is analyzed in a UMTS complaint analysis task, Signaling Procedure Before Call Release in the lower part of the UMTS complaint analysis result window, HHO and SHO in Handover Information on the right of the UMTS complaint analysis result window are empty in the results of UMTS complaint analysis tasks.

Cause The CHR data generation function provided by Huawei RNC in V900R012C01SPC300 and later versions is optimized to reduce the load on the RNC and increase RNC storage capability. After the function is optimized, hard handover information, soft handover information, and signaling procedure before call release in normal release information of the CHR data are shielded. The VIP analysis function is not affected by the optimized function. For the complaint analysis function, however, Signaling Procedure Before Call Release, HHO, and SHO cannot be displayed in the analysis results of subscribers.

Operation Procedure To perform further analysis on hard handover information, soft handover information, and signaling procedure before call release in the normal release information about subscribers in a complaint analysis task, do as follows:

10-20

1.

11 UMTS Cell Performance Analysis

11.1 Basic Knowledge of UMTS Cell Performance Analysis This section describes the basic knowledge of UMTS cell performance analysis, which helps to quickly identify problem cells and enables the Nastar to obtain the data of abnormal calls of problem cells. By analyzing and displaying the data of abnormal calls, the Nastar assists in identifying the causes of problem cells and facilitating in-depth problem analysis.

Cell Performance Analysis Generally, the whole-to-partial analysis method is used during network optimization or performance analysis. That is, the Nastar locates and analyzes network problems by monitoring performance KPIs, and then analyzes the KPIs of the entire network or a specific BSC. Then, the Nastar analyzes cells of a faulty BSC to identify the bottom problem cells. After that, the Nastar performs in-depth analysis on the bottom problem cells. At present, the Nastar can perform cell-level analysis for performance data. The Nastar can provide detailed and in-depth analysis on problem cells. The functions provided by the Nastar are as follows: l

The Nastar analyzes exceptional call records based on the RNC or NE groups and provides top causes of exceptional cells. This helps network engineers to identify the detailed causes of the exception, thus improving work efficiency.

l

After the main exceptions of problem cells are identified, the Nastar provides s with an in-depth understanding of bottom s with poor KPIs by providing the function of analyzing bottom problem s in cells. This function helps network engineers to locate bottom s of an exception type in problem cells. In this manner, network engineers can solve the problems of bottom s, hence improving cell performance.

l

If problem cells are not identified, the Nastar performs exception analysis of a large number of cells under the BSC, which helps to quickly identify the bottom problem cells.

The results of cell performance analysis can be exported as .xls or .xlsx files. In this manner, s can optimize problem cells on the network according to the exported analysis results.

Exception Types The cell performance exceptions are analyzed from two aspects, namely, objective network exception and subjective subscriber experience exception. For details, see Table 11-1. Table 11-1 Exception types and functions
