A large number of measurement counters exist in the M2000 system. Therefore, the
counters are divided into different levels for better and efficient management.
Level 1: function set. A function set consists of multiple function subsets related to
a specific system function. Function sets are also called measurement sets.
Level 2: function subset. A function subset consists of measurement counters
related to a certain system function. Function subsets are also called measurement
units.
Level 3: measurement counter.

According to sources, measurement counters are classified into two types:
System counters: defined by NEs, NEs periodically report the measurement resultsof all system counters to the M2000. System performance counters consist of
default counters and extended counters.
User-defined counters: defined on the M2000 client, namely, custom counters.

After seizing a specific channel, the MS periodically reports measurement reports (MRs) to
the BSC. The BSC performs power control and handover decision based on the MRs. MR
Measurement refers to the measurements related to MRs and helps with network
optimization.

Analysis process
First we shall analyze and compare the item of BSC measurement function to havea rough idea for the whole network.
During analyzing, if any important items (such as call drop rate or handover success
rate) are abnormal, we shall do further detailed analysis for the corresponding
items.

This measurement provides the average number of idle channels (TCHF, TCHH, or SDCCH)
whose interference level are in each interference band (1-5) per granularity period.
Measurement Point
The system accumulates the number of idle channels (TCHF, TCHH, or SDCCH)
whose interference level are in each interference band every five seconds. At the
end of a granularity period, the accumulated number is divided by sampling times.
The result is the average number of idle channels (TCHF, TCHH, or SDCCH) whose
interference level are in each interference band.

Besides use “interference band” to identify the interference , we can use
function ”Frequency Scan”:
Step1: After login LMT, lick “Device Maintenance”.
Step2: Right click any cell in “Device Navigation Tree”, and select “Configure Frequency
Scan”, then pop out the “Configure Frequency Scan” dialog box, check any ARFCN needed
according to the practical and set the “Hour” and “Minute” you want(for example 5
Minutes), and click “Start”, and then click ”Cancel” to close the dialog box.
Stpe3:Right click the same cell in “Device Navigation Tree”, and select “Query Frequency
Scan”, then pop out the page named “Query Frequency Scan”. After 5 minutes, there is
receive level output for all the ARFCNs checked before, shown as following. Usually, we
care both “Main Average” and “Sub Average”.

Receive Level Measurement, together with Receive Quality Measurement per TRX, reflects
the radio signal coverage and interference of a cell. For example, a high ratio of high level
and low quality suggests there may be interference; a high ratio of low level and low
quality suggests poor coverage. This helps to locate the faults in the TX/RX channel, such
as the TRX and the antenna.

[BSC6900 GU] [MR Measurement] [Uplink-and-Downlink Balance Measurement per
TRX]
In an optimum system, power should be well estimated in design to enable the balance
between the coverage of uplink signals and the coverage of downlink signlas. If the coverage of
uplink signals is wider than the coverage of downlink signals, the downlink signals at the cell
edge are weak and easy to be overwhelmed by strong signals in other cells. If the coverage of
downlink signals is wider than the coverage of uplink signals, the MS has to camp on the cell
with strong signals; however, the uplink signals are weak and the speech quality is poor. The
balance does not refer to the absolute balance. The MR on the Abis interface can be used to
check whether the coverage of uplink signals and the coverage of downlink signals are inbalance.

Mapping between the uplink/downlink balance rank and the receive level.
The MR received by the BSC contains the uplink receive level and the downlink receive level. The
uplink/downlink balance factor is calculated through the following formula. The results in dB aregraded from levels 1 to 11, and the number of MRs of each level is calculated.
The formulas are as follows:
Uplink/downlink balance = uplink path loss - downlink path loss
= (actual TX power of the UE - uplink receive level) - (TRX power on top of the cabinet -
downlink receive level)
TRX power on top of the cabinet = TRX initial power - TRX power level x 2 + Power Finetune-
Combiner Loss - downlink dynamic power control level x 2 + dynamic PBT gain
Where: TRX initial power: the power corresponding to the TRX power type, expressed in dBm;
Power Finetune: power fine tune of the TRX; it can be configured by command SET
GTRXDEV (Optional)
Combiner Loss: combination loss of the cell x (0.1); it cab be configured by SET
GCELLPWRBASIC (Optional)
Dynamic PBT gain: if the dynamic PBT function is enabled in the call, the dynamic PBT
gain is 3 dB; otherwise, the dynamic PBT gain is 0 dB.
Dynamic PBT function is enable or not: parameter “Dynamic Transmission DivSupported” is “DPBT(DPBT)”by command SET GCELLCHMGBASIC and parameter
“Send Mode” is “DPBT(DPBT)”by command SET GTRXDEV.

[MR Measurement]
[Uplink-and-Downlink BalanceMeasurement per TRX]
If the balance between the uplink and the downlink is mainly at level 1, you can infer that
the downlink loss is too great or the downlink transmit power is too small. If the balance
between the uplink and the downlink is mainly at level 11, you can infer that the uplink
loss is too great or the uplink transmit power is too small. The balance level helps to locate
the faults in the TX/RX channel, such as the TRX and the antenna.

MR Measurement ->Neighbor Cell Level Measurement per Cell
The measurement unit is used to measure the mean receive level of the neighbor cell. Youcan determine whether to configure the neighbor relation based on this measurement.
When measuring the information of defined neighbor cells, the measurement unit is used
to measure the redundant cells. When measuring the information of undefined neighbor
cells, the measurement unit is used to measure the miss-configured cells. It is
recommended to register the NCELL when deploying a new site and delete the NCELL of
the cells after network optimization. Register less than 50 cells, or the CPU usage of the
XPUM will increased by 10% to 20% at traffic peak.

ERR IND
After the MS seizes a channel, the BTS sends the BSC an ERR IND message,
indicating that call drops occur on the Um interface because of the abnormal
connection at the radio link layer.
If the cause value carried in the ERR IND message is timer T200 expired (N200+1)
times (0x01), unsolicited DM response (0x04), or sequence error (0x07), this
measurement provides the number of call drops due to ERR IND on the basis of the
channel type (SDCCH, TCHF, or TCHH), the service type (signaling or traffic), the
concentric attribute (overlaid subcell or underlaid subcell), and the cause value. CONN FAIL
After the MS seizes a channel, the BTS sends the BSC a CONN FAIL message,
indicating that call drops occur on the Um interface because of the abnormal
connection at the radio link layer.
If the cause value carried in the CONN FAIL message received by the BSC is radio
link failure (0x01), handover access failure (0x02), om intervention (0x07), or radio
resource not available (0x21), this measurement provides the number of call drops
related to CONN FAIL IND on the basis of the channel type (SDCCH, TCHF, or
TCHH), the service type (signaling or traffic), the concentric attribute (overlaid
subcell or underlaid subcell), and the cause value.

REL IND
The connection between the MS and the BTS fails. Therefore, when the BTS in the
multi-frame link set-up state receives the DISC frame from the MS, the BTS sends
the BSC an RELIND message indicating that call drops occur on the Um interface.
No MRs from MS for a Long Time
If the BSC does not receive a measurement report within a certain period (five
minutes by default), the BSC determines that a call drop occurs on the Um
interface.
Abis Terrestrial Link Failure
After the MS seizes a channel, the call may be released because the RSL of the TRX
carrying the channel is broken.
Equipment Failure
After the MS seizes a channel, the call may be released because of the internal
error of the BSC.
Forced Handover
After an MS seizes a channel, if the system initiates a forced handover and the
handover fails, the BSC may initiate a call release procedure.
Resource Check
This counter is measured when the call is released due to the inconsistency in the
check for the internal resources of the BSC.
