Hardware and Software Solution

Hardware Solution:

GSM and UMTS boards are installed in the same BBU3900, whereas the RF

modules for GSM are independent of those for UMTS, and transmission of Abis

interface is also independent of that of Iub interface.

Software Solution:

Software is classified into GSM software and UMTS software. The software of

the two modes runs independently on the corresponding hardware in BBU3900,

and the communications exist only between the main control units of the two

modes. The electromechanical components such as the power supply unit,

batteries, fans, and environment monitoring unit are controlled by the common

control unit in a centralized manner.

Software Solution Software architecture in GU co-cabinet base station consists of two

completely separate software systems: GSM software and UMTS software.

On M2000, a GU co-cabinet base station is presented as two interrelated

network elements.

Equipment Management of GU Co-Cabinet Base Station The equipment management module (also referred to as monitoring

software) manages the common components, processes the data sent

by the GBTS and NodeB, and reports alarms related to the common

components according to the preset rules.

The monitoring software provides a refresh mechanism for the configuration of the

common component data sent by the GBTS and the NodeB. For example, if the

GBTS sends the definition of a Boolean value after the NodeB, the definition sent

by the GBTS overwrites and takes effect. In the case that the GBTS and the

NodeB send different data for the configuration of common components, the GU

co-cabinet base station reports alarms.





Arial

Arial

Equipment Management of GU Co-Cabinet Base Station

The GU co-cabinet base station adopts the preference rule to control the rotation

speed of the common fans. That is, after comparing the data sent by the GBTS

with that sent by the NodeB, the monitoring software will choose the higher speed

to take effect.

The monitoring software reports the dedicated alarms only to the corresponding

side of the base station rather than to the other side. For example, the alarms

generated on the WBBP are reported to the M2000 only through the UMTS

software.

For the alarms of common components, such as fans, power supply unit, and

environment monitoring unit, the monitoring software reports these alarms to both

the GSM software and UMTS software and then to the M2000. Therefore, two

pieces of alarm information of the same common component will be displayed on

the M2000. The main control boards of the GU co-cabinet base station do not

support active/standby switchover.

Hardware Configuration of BTS3900 Configuration Principles of RF Modules:

If the total number of RF modules is not more than six, configure all the RF

modules will in one cabinet. If the total number of RF modules is more than six,

configure all the WRFUs in the extension cabinet (without BBU) and all the

DRFUs in the main cabinet (with BBU) .

In each cabinet, the DRFUs and WRFUs are alternately installed. For example,

if three DRFUs and three WRFUs need to be installed in a cabinet, the DRFUs

are installed in slots 0, 2, and 4 and the WRFUs are installed in slots 1, 3, and 5.

If there are only three RF modules in the extension cabinet, they should be

installed in slots 0, 2, and 4.

Hardware Configuration of BTS3900 Cabling Principles

RF jumpers: RF jumpers are routed inside the cable trough.

In a single cabinet or two cabinets installed side by side, the RF jumpers are routed

inside the cable troughs to the top of the cabinet by default before they are led out of

the cabinet from two sides.

When the cabinets are installed in stack mode, the RF jumpers in the lower cabinet

are routed inside the cable troughs on the two sides of the cabinet, and the RF

jumpers in the upper cabinet are routed upwards and then led out of the cabinet.





Arial


18pt Color:Black



Arial


Transmission cables: Transmission cables must be routed separately from the -48 V power cables.

Transmission cables are routed along the cable trough on the right of the cabinet

(seen from the front), whereas the -48 V power cables are routed along the cable

trough on the left of the cabinet.

Monitoring signal cables for the DCDU-01 and FAN unit: In a single cabinet, the monitoring signal cables are routed according to the principle of

the shortest path.

When the cabinets are installed in stack mode, the monitoring signal cables are routed

along the cable trough on the right of the cabinet (seen from the front).

When the cabinets are installed side by side, the monitoring signal cables are routed

along the cable trough on the right of the main cabinet (seen from the front) to the top

of the cabinet and then routed downwards along the cable trough on the right of the

extension cabinet.





Arial

Arial


CPRI cables In a single cabinet or two cabinets in stack mode, the CPRI cables for UMTS are

routed along the cable trough on the left of the cabinet (seen from the front), whereas

the CPRI cables for GSM are routed along the cable trough on the right of the cabinet.

When the cabinets are installed side by side, the CPRI cables for GSM are routed to

the top of the cabinet along the cable trough on the right of the main cabinet (seen

from the front), whereas the CPRI cables for UMTS are routed to the top of the cabinet

along the cable trough on the left of the main cabinet. In the extension cabinet, the

CPRI cables are routed along the cable trough nearest to the main cabinet. That is, if

the extension cabinet is located to the left of the main cabinet, the CPRI cables are

routed along the cable trough on the right of the extension cabinet; if the extension

cabinet is located to the right of the main cabinet, the CPRI cables are routed along

the cable trough on the left of the extension cabinet.

Hardware Configuration of BTS3900A Configuration Principles of the RF Modules:

If the total number of RF modules is not more than six, configure all the RF

modules in one RF cabinet. If the total number of RF modules is more than six,

configure all the WRFUs in the extension RF cabinet and the DRFUs in the main

RF cabinet.

In a single RF cabinet, the DRFUs and WRFUs are alternately installed. For

example, the DRFUs are installed in slots 0, 2, and 4, and the WRFUs are

installed in slots 1, 3, and 5 of the cabinet. If there are only three RF modules in

the RF cabinet, they should be installed in slots 0, 2, and 4.

Hardware Configuration of BTS3900A Cabling Principles:

The usage of cable holes: The round cable holes are used for the cables between APM30 and RF cabinets in

stack mode.

The rectangular cable holes of APM30 cabinets are used for external cables when

the APM30 is installed in stack mode.

The three rectangular cable holes on each side at the bottom of the RF cabinet are

used for feeders, and the rectangular cable hole in the bottom middle of the RF

cabinet is used for CPRI cables, power cables, and signal cables.

If an RF cabinet is installed separately as a remote unit, the round and rectangular

cable holes at the top of the RF cabinet will not be used.





Arial


18pt Color:Black



Arial


CPRI cables: When the APM30 is stacked on an RF cabinet, the CPRI cables are led through the

round cable hole on the left of the APM30.

When two RF cabinets are installed, the routing of the CPRI cables to the extension RF cabinet is as follows: The CPRI cables are led into the RF cabinet under the APM30 through the round cable hole on the APM30. After led through the rectangular cable hole in the bottom middle of the RF cabinet, the CPRI cables are led into the base and then through the rectangular cable hole in the bottom middle of the extension RF cabinet.

Monitoring signal cables of RF cabinet: For a single RF cabinet on which the APM30 is stacked, the monitoring signal cables

are routed downwards along the cable trough on the right of the APM30 (seen from the front). After leading through the round cable hole on the right of the APM30, the monitoring signal cables are connected to the FMUA in the RF cabinet.

When two RF cabinets are installed, the signal cable between the cascaded RF cabinets is led from one cabinet to the other through the rectangular cable hole in the middle of each RF cabinet.





Arial

Arial


Power cables of RF cabinet: For a single RF cabinet on which the APM30 is stacked, the power cables are routed

downwards along the cable trough on the right of the APM30 (seen from the front).

After leading through the round cable hole on the right of the APM30, the power

cables are connected to the DCDUs in the RF cabinet.

When two RF cabinets are installed, the routing of the power cables to the extension

RF cabinet is as follows: The power cables are routed along the right of the APM30,

through the rectangular cable hole on the right of the APM30, and then along the

support at the bottom. After leading through the cable hole in the bottom middle of

the RF cabinet, the power cables are connected to the DCDUs.

Equipotential cables: The equipotential cable is routed through the round cable holes on the left of the

APM30 and RF cabinets.

The equipotential cable is routed through the rectangular cable holes on the left of

the transmission and RF cabinets.

Arial

Initial Configuration Principles Configuration of the Common Components:

The common components are the fans, PMU, FMU, EMUA, etc. They are

separately configured for GBTS and NodeB. The configuration data takes effect

in compliance with the following rules: The GU co-cabinet base station adopts the preference rule to control the rotation

speed of the common fans. That is, after comparing the data sent by the GBTS with

that sent by the NodeB, the monitoring software will choose the higher speed to take

effect.

The data that takes effect is the data ultimately configured for GSM or UMTS.

Therefore, the common components should be configured for both the GBTS and the

NodeB, and all the related parameters should be set in accordance with the default

GSM data. (For the NodeB, users can manually configure a template data file

beforehand and create configuration files on the basis of this template.)

If the parameters configured for GBTS and NodeB are inconsistent, both the GBTS

and the NodeB report a configuration conflict alarm.





Arial


18pt Color:Black



Arial

Initial Configuration Principles Configuration of the Common Resources:

The external input alarms related to the sensors, such as the door status

sensor, water sensor, smoke sensor, and infrared sensor are separately

configured for the GBTS and NodeB. The configuration data takes effect in

compliance with the following rules: The data that takes effect is the data ultimately configured for GSM or UMTS.

Therefore, the external input alarms should be configured for both the GBTS and the

NodeB, and all the related parameters should be set in accordance with the GSM

data. (For the NodeB, users can manually configure a template data file beforehand

and create configuration files on the basis of this template.)

If the parameters configured for the GBTS and NodeB are inconsistent, both the

GBTS and the NodeB report a configuration conflict alarm.





Arial


18pt Color:Black



Arial

Initial Configuration Principles Configuration of the Transmission and Services:

The transmission and services are separately configured for the GBTS and

NodeB. Configuration of the transmission and services for the GBTS part of the

GU co-cabinet base station is the same as that for the GSM-only base station.

Note that No.0 E1 on the GTMU must be configured, because timeslot 31 of

No.0 E1 is used for the OM channel.

Configuration of the transmission and services for the NodeB part of the GU co-

cabinet base station is the same as that for the UMTS-only base station. The

NodeB supports inter-board IMA. Each IMA group supports a maximum of four

IMA links (E1s).

Configuration of License:

The licenses should be configured separately according to the GSM and UMTS

service capabilities.

Chapter 4Chapter 4 Precautions of Site MaintenancePrecautions of Site Maintenance





Arial


18pt Color:Black



Arial

Precautions of Site Maintenance Boards:

Both WMPT and GTMU boards do not support active/standby switchover.

The clock source of the GBTS is independent of that of the NodeB. The GBTS and the NodeB extract the clock source from their own trunk cable.

When the working reference clock of the BBU3900 is provided by the WMPT, resetting of the WMPT board will not affect the current and subsequent services of the GBTS, and vice versa.

When the working reference clock of the BBU3900 is provided by the WMPT, unplugging and plugging the WMPT board will disrupt the current services of the GBTS but will not affect the subsequent services of the GBTS , and vice versa.

The operation and maintenance of the RF modules on the GBTS and NodeB can be performed separately. The operation and maintenance on the GBTS or NodeB do not affect the running of its counterpart.





Arial


18pt Color:Black



Arial

Precautions of Site Maintenance Common Resources: The common resources are jointly controlled and managed by

the GBTS and NodeB. When performing the operation and maintenance of the common resources, pay attention to the following items:

The configuration data of the common resources must be synchronously modified on the GBTS and NodeB.

The alarms are simultaneously reported to the GBTS and NodeB.

Common Components: The common components are jointly controlled and managed by the GBTS and NodeB. When performing the operation and maintenance of the common components, pay attention to the following items:

Both the GBTS and the NodeB manage the external equipment. Therefore, when you reset the GBTS, the external equipment will also be reset and the NodeB will report an alarm indicating that the external equipment is abnormal. After the restart of the external equipment, the external equipment abnormal alarm will be cleared on the NodeB. The same problem occurs on the GBTS if the NodeB is reset.

Transmission and Services: The operation and maintenance of the transmission and services on the GBTS and NodeB

are performed separately. The operation and maintenance on the GBTS or NodeB will not affect the running of its counterpart.
