normally.

l You have the permission to run MML commands.

Procedure

Step 1 On the M2000 client, choose Maintenance > MML Command. The MML Command window is displayed.

Step 2 Select the BSC6900 in the left navigation tree. The navigation tree of BSC6900 MML commands is displayed.

Step 3 Run the MML command DSP UCELL to query the running status of all cells. Here, set the parameters as follows:

l Set Query type to BYCELL(Query by cell).

l Leave Cell ID empty.

The execution result is displayed. For the meaning of the result, see the Help Information in the upper right area on the interface.

normally.

l You have the permission to query the measurement results of the performance counters.

Context

The measurement counters listed in Table 3-2 should be checked to determine the current performance status of the cell.

Table 3-2 Measurement counters of cell resources

PerformanceItem

MeasurementCounter

Description Expected Result

Number of subscribers in the cell

VS.CellDCHUEs

VS.CellFACHUEs

Measurement object: UCELL

Location of the counters:Measurement related to Radio Resource Control > RRC connection setup measurement per cell

The two counters measure the number of subscribers on the dedicatedchannels and on the common channels respectively.

If the values of both counters are0, you can infer that there are no subscribers in the cell. A fault may occur in the cell.

Measurement of the cell RTWP

VS.MeanRTWP

VS.MaxRTWP

VS.MinRTWP

Measurement object: UCELL

Location of the counters: Measurements related to MeasurementReport > Cell TX and RX Power Measurement per cell

These counters measure the uplink load of a cell.

The measurement value has a positive correlation with the cell load.

Procedure

Step 1 On the M2000 client, choose Performance > Query Result. The Query Result window is displayed.


Step 2 Click New Query... in the lower area. The Query Result dialog box is displayed.

Step 3 Perform the following steps:

2. Set parameters on the Object Settings, Counter Settings, and Other Settings tab pages.

3. Click Query. The query result is displayed.

NOTE

The query result can be displayed in three forms: Table, Line chart, and Bar chart. You can specify the form in the View Type area.

Step 4 Compare the performance counter values with those required for the office. If the values are inconsistent, contact the corresponding personnel for troubleshooting.

NOTE

If the measurement result contains a Reliability field, the measurement result is reliable only when the value of this field is Reliable.

3. Checking the Communication Between NEs and theM2000

This section describes how to check the communication between NEs and the M2000 in theM2000 network topology.

Prerequisite l You have logged in to the M2000 client. The communication between the M2000 client

and the server is normal.

l You have the proper operation authority.

Context

Criterion for the operation: All the NEs communicate with the M2000 normally. If the communication between a NE and the M2000 is disrupted, there is a red cross on the upper left of the NE, as shown in Figure 4-3.

Figure 4-3 M2000 network topology

Procedure

Step 1 Log in to the M2000, and than choose Topology > Main Topology. The Main Topology tab page is displayed. Check the status of each NE in the network topology. Check whether the connections of NEs are normal.

----End

Postrequisite

In routine maintenance, most communication problems are caused by network failure. Rectify the connection problems of the network and the communication problems will disappear.
