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
Traffic Statistic Manual - Volume IIM900/M1800 Base Station Controller Chapter 2 Operation of Traffic Statistics
Huawei Technologies Proprietary
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
Cell Measurement Function Maximum num. of busy TCHs
Power-Control Measurement Function Maximum distance between MS andBTS
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.

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.

Traffic Statistic Manual - Volume IIM900/M1800 Base Station Controller Chapter 2 Operation of Traffic Statistics
Huawei Technologies Proprietary
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.

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.

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

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.

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

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
