Chapter 2 Operation of Traffic Statistics

2.1 Overview

The operation of BSC traffic statistics is implemented on WS (Work Station), and it

mainly includes the following functions:

Maintenance of traffic statistics tasks, including creating, modifying, activating,

halting, deleting and querying.

Graphic display of traffic statistics data. The report of results can be listed in the

format of tables according to the queried text report. The basic querying, resultsorting and result in table printing functions are also provided. Secondary data

analysis and processing can be implemented according to the result data. The

processed data can be displayed in bar chart or curve, etc.

The traffic statistics management system can be used to monitor the network

performance, and provide basis for the network maintenance and optimization. The

major functions of traffic statistics system is task registration, task deletion, task

modification, task status querying, task result analysis, task result printing, and

customized indices, etc.

2.1.1 Brief Introduction

Traffic statistics is mainly implemented with task operation. The rough process of traffic

statistics is shown in Figure 2-1, in which the dotted line symbolizes optional steps.

The task management system enables the user to create traffic statistics task, modify

traffic statistics task, query detailed information of traffic statistics task, query/save/print

the result of traffic statistics task and delete traffic statistics task. The most important

step among them is creating a traffic statistics task. The others are all implemented on

the basis of it.

In addition, BSC traffic statistics system also supports:

Template management

Customized index management

2.1.2 Brief Introduction to Traffic Statistics Operation

The WS of BSC, as the man-machine interface of traffic statistics system, provides the

graphic operation interface shown in Figure 2-2.

2.1.3 Logging in BSC Traffic Statistics System

There are three methods of Logging in BSC traffic statistics system:

In the first method, the WS connects with BSC BAM through OMC Server. In this case,

select [Startup/Programs/Huawei GSM-OMC/OMC SHELL] as shown in Figure 2-3, to

log in OMC SHELL, and then right-click the BSC icon in OMC SHELL. Select [Traffic

Statistics] in the popped up pull-down menu to enter the traffic statistics system as

shown in Figure 2-4.

In the second method, the WS connects with BSC BAM directly. In this case, select

[Startup/Programs/Huawei GSM-OMC/OMC LocalWS] as shown in Figure 2-5to log in

OMC Local WS, and then select [Start/Task/Traffic Statistics] in OMC Local WS as

shown in Figure 2-6to enter the traffic statistics system.

In the third method, the WS connects with BSC BAM directly, too. In this case, select

[Startup/Programs/iManager M2000/Integrated Network Management System] as

shown in the Figure 2-7to log in iManager M2000, and then right-click the BSC icon inM2000 in the popped up pull-down menu to enter the traffic statistics system as shown

in Figure 2-8.

2.1.4 Logging in Traffic Statistics Report System

BSC supports the report operation system under the unified management of Huawei

OMC. This system collects the traffic statistics data from the equipment's of the entire

network to generate the centralized reports conforming to network management

standard.

It is necessary to log in OMC SHELL before logging in report system. In OMC SHELL,

right-click the icon of OMC Server, and then select [Traffic Statistics Report] in the

shortcut menu to enter the main window of report system, as shown in Figure 2-9. Theoperations of traffic statistics reports include create report, delete report, browse report,

print report, save report, and modify configuration information and the time definition of

data collecting. For the detailed introduction to the report system and the operations,

please refer to the section of "System Operation" in M900/M1800 Operation and

Maintenance Center User Manual.

2.2 Points for Attention

Pay attention to the following when using BSC traffic statistics tools:

1) Each traffic statistics task occupies some of the system resources. If too many

tasks are implemented simultaneously or a task is implemented too frequently, too

much resource of BSC system will be used. Therefore, there are restrictions to the

number and period of traffic statistics task in BSC system:

At most 200 tasks can be created in each BM (Basic Module).

At most 3000 subtasks can be created in each BM.

A traffic statistics task is divided into subtasks according to the traffic statistics

objects in the task. The number of traffic statistics objects of a traffic statistics task

equals to the number of the subtasks contained in this task. The number of

subtasks of a BM is the total number of the subtasks of all tasks created in this BM.

For example, if a BM is fully configured to supports 128 cells, there will be 128

subtasks after creating a measurement task of cell performance for "all cells in the

module".

A task can have at most 60 different initial indices.

For example, BSC Measurement Function has more than 130 primitive indices.

Cell Measurement Function has more than 220 primitive indices. At least three

tasks are to be created to measure all indices of BSC Measurement Function. At

least four tasks are to be created to measure all indices of Cell Measurement

Function.


9/56



2-8

Note:

The number of the initial indices contained in a pre-defined index or customized index

equals to the number of initial indices that compose these pre-defined or customized

indices. If an initial index and its pre-defined or customized index are both selected as

the statistic items of a traffic statistics task, this initial index will be measured once only.

There are another three special traffic statistics types: A-interface truck measurement

function, Cell Frequency Scan and Receiving Level Measurement Function. These

three types both contain over 60 primitive indices, but it is still possible to select over 60

initial indices in a task here. Up to 62 initial indices can be resisted to A-interface trunk

measurement function.

Minimum traffic statistics cycle: 15 minutes

If the statistic cycle is too short and the task results are too many, the system burden will

increase. Therefore, the statistic cycle should not be shorter than 15 minutes. The

default setting is 30 minutes. The maximum statistic cycle is 1440 minutes.

Note:

There are two types of special traffic statistics: LAPD Link Measurement Function and

Cell Frequency Scan. Tasks with minimum statistic cycle of 3 minutes can beregistered to the former type, and those with minimum statistic cycle of 1 minute can be

registered to the latter type.

2) User authorities

The user authorities of OMC traffic statistics system are divided into three levels:

service query authority, service configuration authority and service management

authority. See Table 2-1.

3) Statistic items that cannot be registered more than once

Do not register the statistic items concerning maximum/minimum values (e.g.

Maximum num. of busy TCHs) in multiple tasks. Otherwise, the data of these indices

may be incorrect.

The BSC traffic statistics indices concerning maximum/minimum values and their traffic

statistics function types are listed in Table 2-2.

Table 2-2 BSC indices concerning maximum/minimum values

Traffic statistics function type Index concerningmaximum/minimum value

CPU Measurement Function Peak percentage of CPU occupation

Cell Measurement Function Maximum num. of busy SDCCHs

Cell Measurement Function Maximum TCH queue length

Power-Control Measurement Function Maximum downlink power durationpercentage

Power-Control Measurement Function Maximum uplink power durationpercentage

GPRS Related Measurement Function Max num. of available PDCH

GPRS Related Measurement Function Min num. of available PDCH

4) Do not modify the time of BAM and OMC Server.

2-10

Since the management and time of traffic statistics are closely related, if the time is

modified, the result of this cycle that outputted may be incorrect.

2.3 Creating Traffic Statistics Task

I. Analyze Requirements

The demand of traffic statistics usually has the following considerations: routine

maintenance, fault handling and network optimization, etc. Before creating traffic

statistics task, it is necessary to analyze the requirements of the traffic statistics to

decide the parameters of the task.

The following takes the traffic statistics tasks needed during the system normal running

as an example. Assume that this BSC contains two BMs, each of which has 120 cells.For the tasks needed under other situations, refer to the information of various statistic

items in Chapter 3.

1) Basic information

During the normal operation of BSC, the tasks of BSC Measurement Function and Cell

Measurement Functions for each cell should be registered, as which are shown in

Table 2-3.

Table 2-3 Basic tasks needed during the normal operation of BSC

Task Task name Description

1BSC Measurement -Common

2BSC Measurement -Maintenance

The BSC Measurement is realized withtwo tasks. They are usually the routinetype and maintenance type.

3Cell Measurement 1 -SDCCH

4 Cell Measurement 2 - TCH1

5 Cell Measurement 3 - TCH2

6Cell Measurement 4 -Handover

7Cell Measurement 5 -Launch Handover

The measurement of all cells is realizedwith five tasks. They are SDCCH type,

TCH type; handover type and handoverlaunch type.


12/56



2-11

Note:

BSC measurement function and cell measurement function involve a large number of

initial indices, but a measurement task can has at most 60 initial indices. Therefore,

there are usually two tasks created for BSC measurement so as to cover those

important initial indices; there are usually four tasks created for cell performance

measurement. In this example, to stress the pertinence of the measurement result, all

indices are classified into four types and totally 5 tasks created.

The principle for naming the tasks is simple and easy to distinguish.

2) Index information

The index information that should be registered is shown in Table 2-4.

Note:

Since there are a large number statistic items, it is impossible to list all indices in the

above table. For the correspondence between tasks and statistic items, refer to

default statistic item template of BSC traffic statistics system.

Since the implementation of traffic statistics task will occupy some system

resources, and the number of subtasks allowed to be created in the entire BM is

limited, the following principles should be conformed to when creating measurement

tasks:

Select statistic items concerned only;

Arrange the pre-defined indices or customized indices processed from initial

indices in the same task with the initial indices.

3) Object information

IV. Set Statistic Item

The interface for statistic item setting is shown in Figure 2-11. Each statistic item

belongs to the related Statistic Function Type and Measure Type. A task can only

contain the statistic items of the same Statistic Function Type, in other words, all indices

of a measurement task should belong to one or more Measurement types of the same

Statistic Function Type.

For the description of the dialog box illustrated in Figure 2-10, see Table 2-7.

Note:

System assigns certain amount of space for each task. When creating traffic

statistic tasks, system estimates the HDD space necessary for saving each statistic

result within its storage time segment in the BAM according to the number of indices,

statistic cycle, number of statistic objects. If the space needed is larger than the

space available, system will prompt the error information and the possible days for

storage currently, as shown in Figure 2-15. In this case, set the save time again

according to the prompt.

As far as the semi-permanent task are concerned, if the days the statistic task

carried out have exceeded the engaged one, BSC will delete the earliest statistic

result.

Figure 2-15 Error when the measurement result storage time is too long

In Figure 2-13, the setting is that the task is implemented every day from Nov. 12th, and

system measures every 60 minutes and always saves measurement results of the last

60 days.

Note:

If the traffic statistics task has been created and the start time configured is reached,

BSC system will start measurement and output the results.

Figure 2-29 Task statistic result

For the convenience of comparison, BSC traffic statistics system supports the diagram

mode to display the task results more directly and clearly, as shown in Figure 2-30. To

query the task results of an object during a certain period of time, select "by object", and


38/56



2-37

then select an object in the dialog box. To query the task results during a certain period

of time, select "by time", and then specify the time in the dialog box.

In diagram displaying mode, if the diagram contains too many indices, the appearance

of it will be chaotic, thus affecting the analysis. Therefore, a diagram is allowed to

display at most 16 indices distinguished with 16 different colors. The lower area in this

interface is for selecting the indices to be displayed in the diagram. If too many indices

are selected, system will prompt error information.

As to the forms of the diagram, the available choices are Line , Bar and Point

. The property of the diagram can be configured with , as shown in Figure 2-31.

The configuration includes Vertical Range, 3D displaying mode and Grid as well as the

number of data points displayed in each page.

System may simultaneously display many task results. The results user concerned

most may be "submerged" by the unconcerned results. Therefore, BSC supports apowerful function of task result filtering. With this function, user can only view the task

results satisfying the filtering conditions of a specified object in the specified time

segment.

Note:

Make sure to obtain "Task Results" before configuring "Data Query". Otherwise,

will still be gray.

To configure querying conditions, click in the interface in Figure 2-26.

The interface for configuring conditions of querying the task result database is shown in

Figure 2-32.


40/56



2-39

Figure 2-32 Configuring conditions of querying the task result database

In this interface, the "Select Objects" (top-left) is for configuring the object to be queried.

After configuration, system will only provide the results of the selected objects. In

Figure 2-32, the task results of Cell 02 are queried. "Display items" (bottom-left) is

used to configure the statistic items to be queried. In Figure 2-32, the task results

related to all items of this task. "Time Range Setting" (top-middle) is for configuring the

traffic statistics time range of the task. After configuration, system will display the results

satisfying this condition only. "Grouping and Sort Type" (top-right) is for setting the

grouping and sequencing of the task results. In Figure 2-32, the task results are

grouped by time in ascending order. The results in each group are in ascending order.

In other words, the task results are first grouped according to their statistic cycle.

Results output in the same period make up a group. Different groups are sequenced by

time. If the items to be queried are not configured with traffic statistics type, i.e. only theactual values of the items are queried, they will be sequenced by traffic statistics object

in ascending order in the group. To query the maximum value of an item, the

sequencing in the group is not needed, for there will be only one result displayed in

each group. If the results are not grouped, the task results queried according to the

conditions of object, item and time will be displayed in their original order. If the items to

be queried are configured with traffic statistics type, such as maximum value, there will

be only one result of the query. "Item Filtering Condition" (bottom-right) is for

configuring the conditions of task result output. If filtering conditions have been

configured, system will display the results satisfying these conditions according to the


41/56



2-40

object, item and time configured. If no setting made to this part, system will output all

results satisfying other conditions configured. In the example in Figure 2-32, the only

task results with "SDCCH blocking rate" > 10% and "Paging unsuccess rate (PCH

overloads)" > 5% will be displayed. The process of setting "Item Filtering Condition" isas follows:

STEP 1: Decide the filtering conditions. In this example: SDCCH blocking rate > 10%

and Paging unsuccess rate (PCH overloads) > 5%

STEP 2: Configure the first condition. Select Item Name, Operator, and then input their

proper values. Click one of , and . In this example: "T

SDCCH blocking rate", ">" and "10%" are selected, and then click .

STEP 3: Configure the second condition. Select item name, calculation relation, and

input the values, and then select the configured conditions which is at thesame level as this condition in the tab of "Item Filtering Condition Tree", and

finally, click one of , and . In this example: "Paging

unsuccess rate (PCH overloads)", ">" and "5%", and then select

"TermID_20201>10" in the tab of "Item Filtering Condition Tree", and finally,

click .

STEP 4: If there are still conditions to configure, follow this pattern to configure.

After configuration, click in the interface shown in Figure 2-32, and then

select "Item Filtering Condition" to query the finalized filtering conditions, as shown in

Figure 2-33.

is the displayed items. "TermID_2197" refers to the statistic item numbered as 2197;

"Task17" is the name of the database table for saving the task results, "17" is the task

No. when a task is registered at WS, it will be allocated with a task No. "(RDateTime

>= :PDateTimeBeg) and (RDateTime < :PDateTimeEnd)" is the time range of the

displayed results; "(ModNo=1 And CellNo=0) OR (ModNo=1 And CellNo=1) OR

(ModNo=1 And CellNo=2)" is the conditions of object for displaying the task results;

"(TermID_20201 > 10) AND(TermID_20400 > 5)" is the configured filtering conditions.

If "Data Query" has been configured, the task will have another tab "Data Query", as

shown in Figure 2-35. In this tab, the results satisfying the conditions set in "Data

Query" will be displayed. After getting the results, they can be listed in the sequence by

different items by clicking the column headings. In this way, it is possible to query the

results in the sequence by items on the basis of the grouping mode and inter-group

sequencing mode configured before hand.
