Scrambling Code and Cell Transmit Diversity Indication

Note: The query result of a single cell also contains the

configuration information of the channels beside

the general information described above


§2 Cell Management Blocking/Unblocking Cell

Blocking cell: BLK LOCELLTo block a cell is to transfer the service on the cell to a neighboring cell and then close the Tx channels of the cell ， the cell resources are not available

after this operation Unblocking cell: UBL LOCELL

NodeB will open the Tx channels and restore the administration status of the cell. The cell is in service

Auditing resource: ADT RESUse this command to request RNC for audit on the logical

resources between RNC and NodeB

Operation instructions Notes

Check and handle NodeB Active alarms in real time (daily)

1. Check whether there exist Current alarms in physical topology window of M2000 Client.If Current alarms exist in one or more NodeB,then go to step2.

2. If Active alarms exist in one or more NodeB, quenry all Current alarms through query active alarm function in M2000 Client(Select follow options: NodeBs you want, active).

3. Handle all active alarms one by one(Handling process ref. help manual of alarm management system).

4. Record the symptoms, causes and handling process of relevant alarms in “3.2 NodeB Daily Maintenance Record” .

Enable the function of sending relevant alarms to the alarm box.

Use alarm query function in M2000 client Function Position: Fault->Query->Current Alm

Or

Select NodeBs with alarm indicator, then use quenry current alarm function of right button.



Maintenance item


Check and handle NodeB alarm log

1.Quenry alarm statistic data by Alarm Statistic function in M2000 Client (Select follow options: NodeBs you want, set start time as last routine day or earlier ).

2.Save statistic data in file (select CSV type) .

3.Check whether there are some alarms with high report frequence. If exist, check cause and handle it.

4.Check whether there are reset alarms. If exist, check whether power off is take place in NodeB.

§3 Daily Maintenance Operations Maintenance item Operation instructions Notes

Check Cell Status

1.Open M2000 Client and use Report Redirection in right key function to redirect the report to the file.In order to keep report file is clean(Not include other MML result), if the Redirection has been selected you should first cancel Redirection and then execute the Report Redirect again.

2.Execute DSP CELL: MODE=ALLCELL; MML command in M2000 client(You can select all NodeBs in same version)

3.Save the result in file

4.Check whther there exist cell in abnormal or block state.

5.Check whether cell setup time is changed.The time of cell setup should not be changed unless it is resetup for some faults.

6.Analyse the result using tool provide in 《 WCDMA NodeB Routine Maintenance

7.Record(templet).xls 》 .Record the symptoms, causes and handling process of relevant alarms.

MML script: DSP CELL:

MODE=ALLCELL;

Annotation:

All cells should be in

normal or enable state.



Maintenance item


Check Trunk Status

1.Execute DSP UNILNK or DSP IMALNK/

DSP IMAGRP or DSP FRAATM for different

configuration to check all logic links are ok.

2.Execute DSP CP and DSP AAL2NODE and DSP

AAL2PATH to check whether all these

resource’state are ok.

NodeB Routine Maintenance

4.Record(templet).xls 》 .Record the symptoms,

causes and handling process of relevant alarms.

In orde to save your

time, all command

should be exevute in

M2000 client, thus you

can select all NodeBs

once.


§3 Weekly Maintenance Operations

Maintenance item


Check boards status in OMC

Check whether all boards are Logical Available (select all NodeBs in same version).

Open M2000 Client and use Report Redirection in right key function to redirect the report to the file.In order to keep report file is clean(Not include other MML result), if the Redirection has been selected you should first cancel Redirection and then execute the Report Redirect again.

DSP BRD: CN=MASTER; select all NodeBs in NE tree

Record the symptoms, causes and handling process of relevant alarms.

The Logical Available

Status of all boards

that be configured

should be YES.


§3 Quarterly Maintenance Operations Maintenance

item Operation instructions Notes

Backup NodeB data files

Perform full backup after NodeB installation and upgrade and perform data file backup only during routine maintenance afterwards.

Mark the backup files

with the date and

version.

Check spare parts Check the spare parts according to the

registration list. Make sure that the spare parts are complete and in good order.

Supplement necessary

spare parts.

Send the replaced

spare parts for repair.

Analyze the running status and faults of this NodeB and make out a plan against faults

Analyze the faults occurring frequently in this NodeB to improve routine maintenance in the future.

Map out the

maintenance of the

next quarterly.







§4 Relative Concepts of Data FileWhat is the data file?

The data files of the NodeB contain its basic data information. They are

independent of the NodeB software: Data configuration file : it records NodeB configuration informationOperation log file : it records NodeB maintenance information. Equipment archives : it records manufacturing information of all

boards in the NodeB

What is the upload and download?

Upload: You can upload data files from the NodeB to the FTP Server for

viewing, modifying and saving. Upload has no impact on the NodeB

Download: You can download updated data files

from the FTP Server to the NodeB


GUI Mode

§4 Configuration File Upload and Download

Transfer Type: How to select Upload and DownloadDirectory Name : To specify the directory of the configuration file for Upload and DownloadFTP Setting : To set the FTP Server for file upload and download

Note: The FTP Server has to work normally and connect properly to the NodeB in the same Intranet.

There shall be no firewall between the FTP Server and the Node
