Overview of M2000

M2000, using two kinds of working mode, including client and server terminals. The software of

M2000 is made up of client, server and network element adapter, which are independent from

each other. Client software runs on client terminal, while the server and network element adapter

software run on the server terminal.

How do M2000 configure the net? Especially for BSC6000? First, M2000 sends the order, all the

configuration data is written into an XML file. Secondary, uploaded to M2000 by FTP, then the

configured server will fetch the network element¶s configuration data according to MIT trees¶

related interfaces of BSC6000. So, without making any operation of data configurations in M2000we can see all the messages of cells and carrier frequency managed by BSC6000.




Overview of M2000

The functions offered by M2000 are not only the management of performance

counter, but also the centralized managements of topology, configuration, fault,

software and safety.

Main functions offered by performance counter management:

Management of performance counter and objects

Real time measurement functions

Real time monitoring

Management of performance data

Performance alarms

Custom counter

After the connecting between M2000 and BSC6000, BSC will upload a default taskfile of a network element to M2000 server. M2000 will analyze and verify the format

and content of this task file, and then create a new task file according to the

measured counter management, finally descend to network element.





Object measurement

To define the measurement object. Measurement object can be sub

rack or cabinet for physical concept or cells for logical concept.

Measurement object and measurement counter corresponding to each

other. Different measurement object has different measurement

counter, a measurement counter can only be applied for one kind of

measurement object. The counter is divided into several measurement

function integration, one measurement function integration is also

divided into several measurement units which are corresponding to

one kind of measurement object.

While adding network elements, such as new sites, M2000 might not

update object list immediately, we can synchronize the configurations

manually.





In the M2000 network topology interface, select the network element graph needed to

be maintained, open the right button menu and select ´Synchronize CM data´; the

synchronization progress will be displayed on the network element graph.





Most of the BSC6000 counteres are collected by network element itself according to

hours, and a result file is to be created. However, whether these counteres will be

converted into M2000 server database and queried, some settings have to be done.

(register or not, KPI counteres will be saved and available to be queried).

The operations related to traffic statistic of M2000 are included in ³Performance´

menu





Open ³performance´ menu, select ´Object Setting´, then start registering object in the

pop-up interface. Like the graph below, unfold the ³cell´ object, under of which are the

network element (BSC6000),




How to register Counter

According to the source of counter, we can divide them into two parts: system

counter and custom counter. System counter could also be divided into two parts:

Key counter and Extension Performance counter.

The counter defined in M2000 by user is custom counter.




How to register counter

Key performance counter

Important counter of network element, measurement state by default, user

can not cancel the measurement.

Extension performance counter

Non measurement report are not available until we register it, after registering,

it can start, user could cancel the measurement.

Custom counter

Custom counter is a new measurement counter, which is created by portfolio

operation of original counter.

Custom counter is made up of value, constant and integral operators. All system

counteres involved in a certain custom counter must correspond to a same object

type.

The formula defined in custom counter can be nested.

The length of formula must be less than 255 bytes.

User can create, modify or delete custom counter, but can¶t deliver measurement

directly.





Select ³Counter Setting´, register the counter on pop-up interface:

such as the graph below, only the ³Default Counter´ (KPI counter) are automatically

selected when commissioning site, other ³Extended Counter´ has to be selected

manually. Finish selecting, click ³Apply´ or ³OK´.





Architecture of performance measurement counter

The system has a large amount of performance measurement counter. In

order to use and manage conveniently, this counter must be managed

layer by layer.

Layer 1, functional set (measurement set), includes several functional sub

set related to certain aspect of system function.

Layer 2, functional sub set (measurement unit), includes severalmeasurement counter related to certain system function.

Layer 3, measurement counter.





In counter registering interface of M2000, structure of the counter distributes

according to measurement object/business process, level one catalogue distributes

by object, what RNO pays attention to are:

BSC Measurement

Call Measurement

CHAN Measurement

MR Measurement

PAGE Measurement

Call Measurement is the most important, which is separated into several business

process, including access, assignment, handover, call drop and so on.

MR Measurement is traffic statistic of measurement report, it includes traffic volume,interference band, up-down link balance, etc.




How to maintain counter

counter maintenance function includes several aspects:

Synchronize the measurement result of a certain time segment

Subscribe measurement, dynamically examine the result reporting instance

Query reliability instance of measurement result in a certain time segment

Query the loss instance of measurement result in a certain time segment

suspend and resume measurement





The interface of maintenance counter (the graph below), the function buttons referred

before are at the bottom of the interface:





How to maintain counter :synchronize

Synchronize network element data manually, so that the lost measurement data

can be recovered from the network element.





How to maintain counter: subscribe

After subscribing, newly reported performance measurement result will be

displayed in the interface automatically.

How to maintain counter: miss the queried result





How to maintain counter: query reliability

While network element reporting measurement result, the reliability information

will be included, so as to describe whether these data is reliable. It shows the

ratio of the reliable result in the whole measurement result.




How to query counter

Select ³query result´ in performance main menu

Query measurement result according to different conditions (counter/object/time

segment).

Save the set query condition as a template, this template can also be copied and

pasted.

The measurement result can be displayed in the form of table, linearity graph

and histogram.





counter query interface:





Direction of tree structure

In the counter query interface, every login user has his own directory. Unfold the

directory, there is a query template which is belongs to the login user.





Object

Setting

Counter

Setting

Direction of counter query: counter query is to query the database under conditions of object,

counter and time, so these three aspect must be selected in the counter query interface.

Get Result

Others

Setting





In order to create a query, we have to right click on the level 1 tree directory, and

select ³New Query´.





counter selection:





Time selection:





Every new query, there is a ³save template³ button, we can save the template, so that

if we have to query the same counter next time, it can be easily done by clicking the

template.





Query result (in the form of table chart) , most common form.





Query resultin the form of linearity chart





Query resultin the form of histogram





The period of real time counter measurement is less than 30 minutes, commonly 5min or 15min,

for the purpose of trouble shooting (paging or handover) in a short time. Mostly we don¶t use it. In

order to prevent M2000 from data processing overload.

Maintenance and queryoperation of real timecounter is the same asnormal counter, but thefunction entrance





Direction of custom counter operation:

Custom counter is made up of value, constant and operator.

After all the original counter come into measurement status, the user custom counter

will come into measurement status.

All system counteres involved in a certain custom counter must correspond to a same

object type. So as to say: one object type can span function sub set.

User can create, modify or delete custom counter.





Select ³Customer Counter Management´ in the performance menu, M2000 will switch

to custom counter operation interface:





See the graph below:

Select the

query unit

where new

counter is

saved Existing definedcustom counter

After user login, select thecustom counter, and the modify

or delete operation will be

available





Tips of custom counter usage

Naming of custom counter must distinguish obviously from the system self

counter.

Export the custom counter to xml file, and import in other M2000 server.

We can¶t edit the custom counteres created by other user, but we can copy them

in counter browse interface and make use of them convenient.

Custom counter support nested counter , the custom counter set by user can

be used in other counter formula.

When querying custom counter, it must be calculated by M2000. Unlike the

system counter which is calculated at the time while reporting archive. So custom

counter need more query time (V2R6 and its higher version, custom counter will

be calculate at the archive time).





In the new custom counter interface, formula can be copied and pasted directly in formula

editing area.

Threshold management

For the purpose of KPI monitor, we can set a threshold value to manage. M2000 will

use the form of alarm to inform user that the counter has been changed based on the

pre set threshold values. However, the counter reporting can only support minimum

15 minutes granularity. The subsequence version can support the counter reporting

for less than 15 minutes also.

Threshold management includes:

Set threshold according to a certain network element or measurement unit

Two threshold direction: ascent and descent

Four threshold alarm levels: warning, minor, major, critical.

Hysteresis can be set separately.

Threshold can be created, modified, deleted, or suspended.





Threshold management: performance threshold measurement interface





Threshold management: add threshold





Threshold management: modify threshold





Threshold management: suspend threshold

is 11(normal measurement) , 19.5(max measurement) B065 version of V890 can suspend

11(normal) / 6(max) BSCs.





Failing to archive is the main reason, several scenes are described below:

The size of original network element reporting file in M2000 server is 0K, which

results in failing to read the real data.

Due to bad transmission condition between M2000 and BSC, error files will be

created.We need to delete these files before archive. M2000 version

V2R3C01B065SP04 and its subsequence version can solve this problem.

High amount of data query leads to deadlock of database

Cleaning the database and restart M2000 server are needed, for BSC6000, we

must strictly control measurement object activation data related to Neighbor cell

measurement.

Register 15 minutes traffic statistic, leads to slow data archive:

Close short period traffic statistic, or it would cause large amount of data needs

to archive on the hour, it would also delay the normal period traffic statistic to

archive.





Common problems

After query result files saved as .EXCEL, number format is saved as text format,

which leads to failure to edit the data directly

R3C01B065SP03 and its earlier version, we need to transfer the data or save it

as .CSV format.

R3C01B065SP04 version, number can be saved directly.

counter query/register interface, how to do if all counteres needed to be selected?

Drag the scroll bar to the bottom, and click ³all item´, that¶s ok.

Some appraisal counteres of customer need to be calculated by custom formula,

but the query is very slow, how to do? Suggest not use custom counter in M2000, export the original counter, write

macro/formula ourselves to improve the speed.




Direction of M2000 version¶s new supported function

Evolution of M2000 version

CME imported New version is not only enhanced on performance statistic, but also imports CME module on data

setting, which can support both import and export EXCEL format of all network optimizing parameters.

The adding of CME function can make user deal with daily parameter modifying and operation related

to network optimizing efficiently. Besides, between different network elements, some matching

functions can be implemented automatically: for example, automatically cell data modifying after sites

swap to other BSC.

MML imported

Import of MML can improve the efficiency of daily data modifying and querying.

Man-machine interface optimized

Function persistence optimizing: real time monitor of counter, cooperate with network

element to complete less granularity counter monitor.

Query report: many sheets can be set in one report, and it can include differentmeasurement object/counter; at the same time, we can set TopN query or conditional display.
