CellAvailability Cause Troubleshooting

Cell databaseconfigurationerror

The data configuration ofcells in the PCU isincomplete.

(1) On the PCU Command Terminal, run thecommand pcu check cellconfig to check thedata configurations of the PCU. Modify thedata configurations according to the errorindications.(2) Check the configuration data (CellChannel Description Table) of the BSC.Check whether the corresponding cells areconfigured with the PBCCH but the PCUlicense does not permit this function.Purchase the license permitting the PBCCHfunction from Huawei or delete the PBCCHconfiguration from the BSC according toyour requirement.(3) Check whether the cell is configured withthe PDCH in the BSC data configuration. Ifno PDCH is configured, configure it.(4) Check whether the cell is configured withmultiple PBCCHs in the BSC dataconfiguration. If you have purchased thecorresponding license, you can configure thePBCCHs. Each cell can be configured withonly one PBCCH. Delete the redundantPBCCHs.

Cell is deactive The cell does not exist in theBSC configuration data.

Compare the configuration data in the ATTRtable of the PCU with that in the cell table ofthe BSC. Check whether the cell is activated.

Checking the BSC Management Status of Cells

If the BSC management status is Blocked, the cells under the BSC are faulty. You have to handlethem.

1. On the LMT, check the status of BTSs and cells and ensure that all the cells are normal. Ifsome cells are faulty, contact Huawei for technical support.

2. Unblock cells on the LMT.3. On the PCU Command Terminal (or LMT), open the PB interface information trace

window and trace the Pb interface information of the faulty cell. On the PCU commandterminal, run the command mt gcell reset to reset the cell. Save the interface informationand contact Huawei for technical support.

Checking the Gb Interface Management Status of Cells

If the Gb interface management status of cells is Blocked, do as follows:

1. Run the command mt fr bc show statinfo. If the bc state is Q933 invalid, run the commandmt nsvc show state. If the NS-VC state is Dead-blocked, you can infer that the FR dataon the PCU is inconsistent with that on the SGSN or the physical line between the PCU




Issue 03 (2009-07-20)

and the SGSN is abnormal. You have to confirm that the FR data on the PCU and that onthe SGSN are correct and consistent. Then configure a test BC in DCE mode on an idleport on the PCU and use an E1 to connect the service port and the test port to perform theloopback test. If a fault occurs, contact maintenance engineers to handle it.

2. Run the command mt fr bc show statinfo. If the FR BC state is normal, run the commandmt nsvc show state. If the NS-VC state is Alive-blocked, you can infer that the NSVC isblocked manually on the PCU or on the SGSN. You have to unblock the NSVC.

3. Run the command mt nsvc show state. If the NS-VC state is normal, run the commandmt bvc signal show state. If the SIG BVC state is abnormal, you can infer that the NSEdata on the PCU is inconsistent with that on the SGSN. You have to modify the NSE dataon the PCU or on the SGSN to ensure that they are consistent. Then run the command mtbvc signal reset on the PCU command terminal to reset the NSE.

4. Run the command mt bvc signal show state, if the SIG BVC state is normal, run thecommand mt bvc ptp show state. If the PTP BVC state is BLOCKED, you can infer thatthe PTP BVC data on the PCU is inconsistent with that on the SGSN. You have to modifythe PTP BVC data on the PCU or on the SGSN to ensure that they are consistent. Then runthe command mt bvc ptp reset on the PCU command terminal to reset the PTP BVC.

Checking the Data Configurations of PCU Cells

Run the command mt bvc signal show state. If the SIG BVC state is normal, run the commandmt bvc ptp show state. If the PTP BVC state is normal, you can infer that the data configurationsof cells in the PCU are incorrect. Run the command pcu show attr and cell show to check andmodify the data configurations of cells.

If the fault persists, contact Huawei Customer Service Center.

4.9.1 Basic Knowledge of BSS Data BackupThis describes the basic knowledge of data management that you must know before performingdata management operations.

NE Data Backup on the M2000

The M2000 provides the function of backing up the NE data. Through this function, all NEconfiguration files and the dynamic data that changes when NE is running can be backed up.

The NE data can be backed up either periodically or manually. A backup file, however, isgenerated on the M2000 server every time a backup task is performed regardless of the backupmode.

The M2000 supports a maximum of 50 NE backup tasks.

The number of backup files that can be saved on the M2000 server is determined by the M2000configuration file. Currently, the M2000 supports a maximum of seven backup files of an NE.When the number of backup files of an NE is greater than seven, the file backed up at the earliesttime is automatically deleted and the NE backup list is updated.

The backup file is saved to the M2000 server/export/home/sysm/ftproot/NE type/data type/NE FDN directory.

l The naming convention for the manually backed up file is BAKDATA+current time.

l The units of Period can be set to days, weeks, and months.

l Periodic backup can be classified into full backup and incremental backup.– Every time a full backup task is performed, the system deletes the earlier full backup

files and incremental backup files on the server. Only the latest full backup compressedfile is stored. The full backup file must be named in the format of all-current time, forexample, all-20060106103055.tar.gz.

– Every time an incremental backup task is performed, a new backup file is generated.The incremental backup task is performed on the basis of the earlier backup. The earlierbackup can be a full backup or an incremental backup. The incremental backup file mustbe named in the format of inc-current time.

BSS System Data Backup

The BSS system data backup consists of the configuration data backup and data backup beforemajor events.

l Routine data backupRoutine data backup is performed to save the data that is generated during the dailyoperation of the system. In the case of exceptions, you can use the backup data to restorethe data and to prevent huge loss.– BSC or BTS configuration data backup

– Huawei recommends that you back up the BSC or BTS configuration data once aday.

– The device that stores the backup data should be kept properly and labeled withdetailed descriptions.
