IV. Test Result Analysis
The analysis of the RTWP test result is as follows:
If the NodeB is not connected to the antenna and feeder system or a matched load,
the RTWP is about –108 dBm.
If the NodeB is connected to the antenna and feeder system (with TMA switched
on) or a matched load, the RTWP is about –105 dBm.
If the servicses are normal and the uplink load reaches 75%, the RTWP is 6 dB
higher than the RTWP when the NodeB does not carry any service.
Note:
When the RTWP reported is valid, the curve is normal. The vertical axis
corresponds to the reported RTWP with unit of 0.1 dBm.
When the reported RTWPs are invalid, abnormal RTWP curves are displayed. The
RTWPs for the main antenna form a horizontal line at –1120 dBm on the vertical
axis. The RTWPs for the diversity antenna form a horizontal line at –1115 dBm on
the vertical axis. The error may lie in the absent MTRU/MRRU, a broken link, or a
faulty channel. In this case, you shall clear the fault first.
9.6 Testing NodeB Clock

NodeB LMT User Guide
The reporting periods of phase discrimination value and DA value are different. The
reporting period of phase discrimination value is 1 second. The reporting period of DA
value depends on the type of the clock source.
For the GPS or BITS clock source, the reporting period of DA value is 2 minutes in
normal condition. If there is fluctuation or frequency deviation on the clock, the
period may be longer than 2 minutes. It is normal if the first reporting period is
greater than 2 minutes.
For the Iub clock source, the reporting period of DA value is 30 minutes in normal
situation. If there is fluctuation or frequency deviation on the clock, the period may
be longer than 30 minutes. It is normal if the first reporting period is greater than 30
minutes.
2)
Phase discrimination value
If the difference of the reported phase discrimination value and the actual value
(10 MHz) is greater than ±1 Hz, you need to check whether there is problem in the
clock source.
9.7 Scanning NodeB Rx Frequency
I. Introduction
The Rx frequency scanning helps you examine electromagnetic environment and
internal interference of the NodeB.
The process is as follows: The MTRU/MRRU scans the frequency, calculates the
strength of received signals, and then reports the result.
II. Prerequisites
It is recommended to do Rx frequency scanning before cell configuration.
The MTRU/MRRU must be blocked before Rx frequency scanning starts.

the shortcut menu to delete the task and curve.
IV. Test Result Analysis
The test result analysis of Rx frequency scanning is as follows:
If the NodeB is separated from the antenna and feeder system, the curve has
jumps greatly higher than –108 dBm. This indicates that there must be internal
interference of the NodeB.
If the NodeB is connected to the antenna and feeder system with NTTA powered
on, the curve has jumps greatly higher than –105 dBm. This indicates that there
must be external interference of the NodeB.
The shape of jumps tells the interference type in most cases:
A triangular or trapezium jump: There are broadband interferences. The peak of
the jump is the central frequency of the interference.
A rectangle jump or a jump added with a rectangle: There is individual tone
interference. The central point of the upper side of the rectangle is the interfering
frequency.

The test result is invalid when there is signal loss or out-of-synchronization frame. In
this case, all the indices should be 0.
The indices in the E1/T1 performance routine test results include
Line Conflicting Error Rate: measures conflicts in line code type.
Framing Error Rate: measures errors in frame synchronization signals.
CRC Error Rate: measures errors in CRC4 multi-frame receiving.
Ebit Error Rate: measures errors in CRC4 multi-frame transmitting at the peer
end.
The above indices reflect the transmission status of the E1/T1 link, which is related to
the code and frame structure of the link.
If an error occurs, check that the code types and frame structures at both ends of
the link are the same.
If they are the same but the error still exists, check the clock status. This is
because of vibrations of the clock.
9.14 Routine Testing STM-1 Performance
I. Introduction
The STM-1 performance routine test shows the STM-1 link status.
This routine test has no negative impact on the services and can be done by the MML
command only.
II. Prerequisite
The STM-1 link has no physical damage but has error bit in transmission.
III. Procedure
Follow the steps below to perform the STM-1 performance routine test:
1)
Execute
the
MML
command
2)
Note down the ID for the task under test.
of
STR
STM1RTTST.
An STM-1 performance routine test is started.
Note:
When the STM-1 performance routine test is started, the NodeB assigns an ID to
each task and sends it to you. With this ID, you can query the task under test.
If you lose the ID, execute the MML command of LST RTTST to get it.

3)
Wait for a while longer than the test time set by the MML command of STR
STM1RTTST. Execute the MML command of STP RTTST to stop the test.
Then the system displays the results of the STM-1 performance routine test.
IV. Test Result Analysis
You can tell the STM-1 link status by the STM-1 performance routine test in real time.
Any error in the test results indicates a line fault.
The test result is invalid when there is signal loss or out-of-synchronization frame. In
this case, all the indices should be 0.
The indices in the STM-1 performance routine test results include
LOCD Event Rate: measures lost cells.
Rx Corrected HEC Error Rate: measures HEC errors because of single-bit errors
during cell delimitation.
Rx Uncorrectable HEC Error Rate: measures HEC errors because of multi-bit
errors during cell delimitation.
Off Event Rate: measures errors in SDH frame synchronization.
Line BIP Error Rate: measures line bit errors.
Section BIP Error Rate: measures section bit errors.
Path BIP Error Rate: measures path bit errors.
Line FEBE Error Rate: measures bit errors in receiving on the line.
Path FEBE Error Rate: measures bit errors in receiving on the path.
Idle Cell Rate: measures wrongly inserted cells.
Tx Cell Rate: measures cells sent over the UTOPIA port.
Rx Cell Rate: measures cells received over the UTOPIA port.
The above indices reflects the receive status of the STM-1 link. STM-1 link status
depends on the cable clock and the physical status of the link. If there is any error,
query the alarm and line clock status.

11.4 UL 141 Test
11.4.1 Introduction to UL 141 Test
The UL 141 test is to test the RF performance of the NodeB Rx channels. During the
test, the NodeB sets up UL channels between the boards of MTRU, HBBI and HULP
(NULP).
According to different UL channels, the UL 141 test is divided into
UL DPCH 141 test
UL RACH 141 test
UL HS-DPCCH 141 test
The test process is as follows:
1)
Use a signal generator to transmit signals for the UL 141 test. For any type of 141
test, the NodeB only receives and displays the measured BER/BLER values on
the LMT interface.
2)
Adjust the transmitted signals until the BER/BLER values meet the RF
performance requirements.
3)
Record the data measured.
Then you get the test result. You can verify the result with the 3GPP TS25.141 protocol.
The UL 141 test items include
Reference receive sensitivity
Dynamic range of received signals
Adjacent channel selectivity
Blocking feature
Intermodulation feature
Rx spurious emissions
Internal BER/BLER verification
During the test, select different test items for different NodeB RF performance. For
details, see the 3GPP TS25.141 protocol.

Chapter 12 Managing NodeB Clock
Chapter 12 Managing NodeB Clock
12.1 About This Chapter
This chapter presents knowledge of the NodeB clock and means of maintaining the
clock.
12.2 Overview of NodeB Clock
12.2.1 Principle of Clock
The NodeB clock module is mounted on the NMPT to provide timing signals for the
NodeB. Under normal conditions, the NodeB clock works in the phase-lock mode. It
keeps precision by tracing the assigned high-precision reference clock source.
There are three reference clock sources for the NodeB:
Iub interface clock
GPS clock
External clock
Only one clock synchronization mode is available at the same time.
When the NodeB clock synchronization source is faulty, the NodeB works in free-run
mode. This enables the NodeB clock to run for another 90 days.
12.2.2 Center Frequency DA Value
The center frequency value is also called center DA value. When the NodeB is in
normal operation, the master clock frequency is about 10 MHz, which is output from the
Oven Controlled Crystal Oscillator (OCXO) in the NMPT. Fine tuning on the main clock
frequency can be realized by adjusting voltage on the OCXO. The quantized value of
the voltage corresponding to the exact 10 MHz is referred to as the center frequency
DA.
12.2.3 Current Frequency DA Value
The current frequency DA value is also referred to as current DA value.
When the NodeB clock works in the free-run mode, the current DA value is the
same as the center DA value.
Huawei Technologies Proprietary
12-1
NodeB LMT User Guide
Chapter 12 Managing NodeB Clock
When the NodeB is using a reference clock source, the current DA value of the
NodeB clock synchronizes with the frequency of the clock source. Namely, the
current DA value is adjusted according to the frequency difference of the clock
source during the software phase-locking.
If the external clock source stays locked for seven consecutive days, it shows that
the clock source is stable. In that case, the clock module shall overwrite the center
DA value with the current DA value. Upon resetting the NMPT or the NodeB, the
current DA value shall be overwritten with the center DA value.
12.2.4 Initial DA Value
The initial DA value is the center frequency DA value preset in the NMPT before its
delivery. When the NodeB is started for the first time, this value is written into the
configuration file as the center frequency DA value. Therefore, the initial DA value can
be regarded as the center frequency DA value preset before the NodeB delivery.
12.3 Querying Clock Status
12.3.1 Overview of Querying Clock Status

Setting NodeB clock work mode
Setting NodeB clock source
Testing NodeB clock source quality
12.4.2 Introduction to NodeB Clock Source
The NodeB needs to lock to an external clock to calibrate its master clock frequency.
Then the external clock is the clock source.
There are three clock sources available for the NodeB, including
Iub interface clock source: It is the default setting by the system. The NodeB
extracts clock signals from the Iub interface between NodeB and RNC as its
reference clock source.
External clock source: The NodeB locks to a 2.048 MHz external clock as its
reference clock source. The clock source can be a BITS clock or a clock at the
synchronous interface of the SDH equipment.
GPS clock source: The NodeB uses the clock signals generated from the GPS
receive card built in the NMPT as its reference clock source.
12.4.3 Setting NodeB Clock Work Mode
I. Introduction
Caution:
This operation causes faults easily.
Do Not execute this command without Huawei technical support.
The NodeB clock work modes include lock mode and free mode.
The clock work mode can be set to "lock" only when there is an external reference
clock source.
Huawei Technologies Proprietary
12-5
NodeB LMT User Guide
Chapter 12 Managing NodeB Clock
When the clock work mode is "free", the NodeB clock works in the free-run mode
and the clock source does not work.
If the clock source is faulty and needs calibrating, set the work mode into the free
mode and then calibrate the frequency value to the center frequency DA value.
This action is usually performed together with actions in subsection 12.5.4
"Setting NodeB Clock Current Frequency ".
You need to set the NodeB clock work mode before setting the current frequency
value.
II. Prerequisite
Be sure to set the clock work mode one minute after the NodeB initialization.
III. Procedure
You can modify the NodeB clock work mode by the MML of MOD CLKMODE only.
12.4.4 Setting NodeB Clock Source
I. Introduction
The NodeB needs to lock to an external clock to calibrate its master clock frequency.
Then the external clock is the clock source.
You must select a proper clock source for the NodeB before it starts running. The
system automatically locks to the clock source after setting the clock source. There is
no need for other manual settings.
II. Prerequisites
Be cautious about the following items before you set the clock source:
To use the Iub interface clock or GPS clock, make sure the clock source is
available.
To use the GPS clock, make sure there is a GPS card on the NMPT. If there is a
GPS card, execute the MML command of DSP GPS to check whether the GPS
clock source is available. You can set the clock source only when the GPS clock
source is available.
To use the Iub interface clock, set the Iub interface and the Iub interface board
from which the NodeB extracts clock signals. And then check the settings by the
MML commands of DSP IUBCLK, ADD IUBCLK and RMV IUBCLK.
III. Procedure
You can set the reference clock source by the MML command of MOD CLKSRC.

Chapter 13 Managing NodeB Cells
13.1 About This Chapter
This chapter describes knowledge of the NodeB cell and means of managing the cell.
13.2 Overview
13.2.1 Local Cell and Logical Cell
A local cell is an integration of physical resources (hardware and software resources) of
a cell in NodeB. The local cell relates to the implementation of a device. Local cells are
configured on and managed by the NodeB.
A logical cell is a standard logical model of cell radio resources controlled by an RNC. It
is independent from the implementation of the NodeB local cell. Logical cells are
configured on and managed by the RNC.
One logical cell corresponds to one local cell.
13.2.2 Cell Radius and Handover Radius
Definitions of cell radius and handover radius are as follows:
Cell Radius: refers to the access radius of a cell, that is, radius of the coverage
area. A UE in the coverage area of a cell can access the cell in theory.
Handover Radius: refers to the radius where a UE is handed over from the source
cell to the target cell. The inner handover radius is defined to avoid resources
waste by preventing frequent handover of the UE between the margins of the two
cells. The UE is handed over only when the UE oversteps the inner handover
radius.
Relations between the cell radius and the handover radius are as follows:
The cell radius refers to the cell outer handover radius. It is greater than the cell
inner handover radius. The area between the two radiuses is the handover area of
the cell.
There is overlap between the access radiuses of two cells. This prevents call
drops during the UE handover and ensures cell breathing.
There is no overlap between the inner handover radiuses of two cells. This
ensures an area for handover.
Huawei Technologies Proprietary
13-1
NodeB LMT User Guide
Chapter 13 Managing NodeB Cells
There shall be an overlapped area between the inner handover radius of the
source cell and the access radius of the target cell. Handover is not available in
this area to reduce the handover area between two cells and avoid frequency
handover.
13.2.3 Cell Status
There are the following categories of cell status.
I. Local Cell Status
The local cell status consists of
Local Cell Unavailable-All Resource fault
Local Cell Unavailable-RF and Baseband Interface Resource fault
Local Cell Unavailable-RF and Baseband Resource fault
Local Cell Unavailable-RF Resource fault
Local Cell Unavailable-Baseband and Baseband Interface Resource fault
Local Cell Unavailable-Baseband Interface Resource fault
Local Cell Unavailable-Baseband Resource fault
Local Cell Available-NCP fault
Local Cell Available
II. Cell Operation Status
Enable: The logical cell has been set up and ready for use.
Disable: The logical cell is not available.
III. Cell Administration Status
Unblocked: The cell is not blocked. It works normally. You can block a cell in this
state.
Shutting down: It is a transitional state before the RNC delivers a block response.
The RNC delivers a block response only after a period or after the cell is idle.
Blocked: The cell has been blocked. You can unblock a cell in this state.
13.2.4 Blocking Cell
There are three modes to block a cell:
High: blocking now
Normal: blocking by schedule
Low: blocking when resources are idle
High is of the highest priority at the risk of partial service loss.
Huawei Technologies Proprietary
13-2
NodeB LMT User Guide
Chapter 13 Managing NodeB Cells
If you select Normal, you may specify a period (1 to 3600 s). During this period, the cell
no longer carries new services. After this period, the system blocks the cell even if it is
carrying service.
Low is of the lowest priority. In this mode, the system blocks the cell only when the cell
does not carry service.
13.3 Querying Cell Configuration
13.3.1 Overview of Cell Configuration Query
Querying cell configuration includes:
Querying cell configuration
Querying cell status
13.3.2 Introduction to Cell Configuration and Cell Status

the cell running status and maintain the cell.
II. Prerequisite
None.
III. Procedure
Query the status of the local cell and the logical cell by the MML command of DSP
LOCELL.
13.3.5 Auditing Resources
I. Introduction to Resource Auditing
The NodeB resources may change, for example, when a board is replaced or the
NodeB configuration is modified. In this case, the logical resources between the RNC
and the NodeB are inconsistent.
Huawei Technologies Proprietary
13-4
NodeB LMT User Guide
Chapter 13 Managing NodeB Cells
To inform the RNC about changes in the NodeB resources in time,
1)
The NodeB sends a resource audit request to the RNC.
2)
Then the RNC adjusts logical resources according to audit report.
As a result,
1)
Logical resources between the RNC and the NodeB are balanced.
2)
The NodeB resources are fully used.
II. Prerequisite
None.
III. Procedure
Proceed with resources auditing by the MML command of ADT RES.

Huawei Technologies Proprietary
13-5
NodeB LMT User Guide
Chapter 13 Managing NodeB Cells
13.4.4 Blocking/Unblocking Cell
I. Introduction
To block a cell is to
1)
Transfer services on a cell to a neighboring cell.
2)
Then close the Tx channels of the previous cell.
The cell resources are not available after this operation. In this way, you can maintain
the faulty NodeB without interrupting services.
After blocking the cell, the NodeB switches off the Tx channels of that cell. The
logical resources related to the cell are regarded as blocked.
After unblocking the cell, the NodeB switches on the Tx channels and restores the
administration status of the cell. The cell is in service.
II. Prerequisite
None.
III. Procedure
Block a local cell by the MML command of BLK LOCELL.
Unblock a local cell by the MML command of UBL LOCELL.

14.4 Upgrading NodeB BOOTROM
14.4.1 Overview
To upgrade the NodeB BOOTROM is to upgrade all the BOOTROM software of each
board on the NodeB.
14.4.2 Introduction to BOOTROM Software
A BOOTROM is a writable and erasable storage medium for binary data (machine
code). The BOOTROM software refers to the software bound with hardware. It provides
basic device drive function and can be started and updated manually.
All the boards on the NodeB have the BOOTROM software. For a macro NodeB, the
NAOI and the NDTI both are equipped with BOOTROMs that are located in the master
CPU and the slave CPU.
The BOOTROM software is a compressed file with the fixed filename of NodeB.pck.
14.4.3 Procedure of Upgrading NodeB BOOTROM Software
