Location of the CME
The CME is a part of the OSS solution, and is the core of the integrated configuration solution for multi-mode
radio network provided by Huawei. In addition, the CME supports typical scenarios of UMTS and GSM networks,
such as initial site deployment, network capacity expansion, BTS swapping, and routine configuration adjustment.
The CME11.0 provides a solution for the unified management configuration of the GSM/UMTS/LTE (GUL).
For the GSM network, the BSC6900 working with the CME provides the GUI data configuration function.
For the UMTS network, the CME is an evolution of the WRAN CME V100R008.
For the LTE, the CME works with the eRAN2.0/eRAN2.1 and provides functions such as site deployment and
routine maintenance.
The CME11.0 supports the SRAN6.0 and the downward overall solution.

Advantages of the CME
GUL Multi-mode Configuration
The configuration on the GSM, UMTS, and the LTE is synchronized and the configuration consistency on the GSM, UMTS, and the LTE is checked to
ensure that the GUL resources are centrally managed.
In the BSC6900, the GSM, UMTS, LTE, and MBTS use the unified device panel to implement the centralized management of the GSM/UMTS devices.
GUI Enhancement
The TOPO site deployment, BTS networking, TRXs of each cell, and timeslot allocation can be viewed in GUI mode on the LMT of the BSC6000.
Therefore, the BTS configuration and resource allocation can be displayed clearly.

Advantages of the CME (Continued)
Improvement on Operation Efficiency
The network-level configuration is centralized. Single BSC multiple BSC
Configuration of a single BTS Configuration of BTSs in batches through the templates
The BTS swapping within a BSC and that between the BSCs can be implemented. In addition, the data
adjustment of neighboring cells can be implemented automatically, saving time for script preparation by
network optimization engineers.
The files configured in offline mode dynamically take effect, improving the file configuration in offline mode.
On the LMT, DAT files configured in offline mode can take effect only after the BSC is reset. In this
case, services are greatly affected.
On the CME, after files are configured in offline mode, corresponding MML scripts are generated so
that these files can take effect when the MML scripts are delivered dynamically. In this case, the BSC is
not reset and services are not affected.
Compared with the LMT of BSC6000, the CME supports the multi-user concurrent configuration in online
mode.
The data browsing capability and retrieval capability on the entire network are greatly improved.
Security The CME provides the function of data check on the entire network before data is activated, including the
check for completeness, redundancy, and consistency.
The CME supports the data rollback in key scenarios.
The CME supports the parameter comparison. That is, the CME compares the data that has taken effect and
the template to check whether data configuration is correct.

Triple Area
Triple area: current area, planned area, and fallback area
Current area
Current area is a network data mirroring area used to save the configuration data of the live network.
Data in the current area is read-only and cannot be modified directly to ensure the security of the
network.
Only one current area is available for a network system.
Through the CME, the data of the live network can be periodically or automatically synchronized to the
current area. Alternatively, users can manually synchronize the data of the live network to the current
area.
Planned area
Planned area is a data planning area that is created with the data of a certain NE system.
Users can perform data planning in the planned area. Different users can create their respective
planned areas. The planned areas are independent of each other.
After implementing data planning in the planned area, users can export the generated data scripts.
After executing the data scripts to the NE, users can make the data take effect.
Fallback area
The rollback command scripts are generated in the fallback area to perform rollback.
When configuration adjustment effects are not ideal, the CME can quickly roll back to the original
configuration status.
Currently, the CME supports the rollback on the GSM side in only three scenarios: RNP import,
modification of radio algorithm parameters in batches, ARFCN import. In addition, the CME supports
the rollback in all adjustment scenarios on the UMTS side in versions later than BSC6900
V900R012C01 (UMTS only). For LTE, CME supports the rollback in all adjustment scenarios..

Data Flow
Three areas: live network, current area, and
planned area.
Interaction of data flow
Planned areaCurrent area: Datamodification in the planned area does not
affect data in the current area.
Planned arealive network: Data
modification in the planned area takes
effect on the live network by generating
and activating data scripts. Before the
changed data is delivered, data on the live
network is not affected.
Live networkcurrent area/planned area:
Data modification on the live network will
be updated in the current area but cannot
be updated in the planned area.

Synchronization in the Current Area
Synchronization mechanism
Full synchronization: All configuration data is uploaded from the NE to
the current area and the data previously saved in the current area isoverwritten completely. The history data of the current area cannot be
saved.
Differentiated synchronization: The data modified in the MOC tables of
the NE is uploaded to the current area. Therefore, the synchronization
efficiency is improved. The incremental synchronization is always used
for daily operations.
The incremental synchronization is supported since BSC6900.
Synchronization method
The data synchronization can be performed periodically, automatically,or manually. The data synchronization of the current area is performed
in firm real time.
The data synchronization is performed automatically in the following
cases:
The CME receives the AVC message reported by the NE and
receives no other messages within two minutes.
A BSC is created on the M2000 and data synchronization has
been complete.
Data synchronization has been performed on the NodeB or TGW
on the M2000.
The script data has been successfully activated.

Creating a Planned Area
Planning a planned area
Based on the data in the current area, multiple planned areas can
be created and a network can be planned concurrently.
The data conflicts between the planned areas can be found only
when the data in the planned areas takes effect on the live network.
If the data conflicts between the planned areas occur, the data in the
planned areas fails to take effect and are mutually overwritten. As a
result, the operation of the NE is affected.
To prevent the data conflicts between the planned areas, data
planning engineers should rationally plan the data in the planned
areas (such as cell index or TRX index) to ensure that the data in the
planned areas is not mutually overlapped.
Creating a planned area:copy the data of NEs from the current
area to the planned area.

Generation of Scripts
The CME supports two types of MML/XML file: differentiated data MML/XML file and full data
MML/XML file.
BSC and BTS: MML commands will be generated; NodeB and eNodeB: XML file will be generated. Differentiated data MML/XML scripts: MML/XML configuration scripts are generated based on
modified contents.
This type of command is generated during the configuration of the planned area and is related to the
configuration process.
This type of command supports the exporting of modified contents separately by exporting multiple
differentiated scripts in the same planned area.
This type of command supports all configuration operations and is applicable to the scenarios such asparameter modification, radio network planning, and optimization.
Full data MML/XML scripts: MML configuration scripts are generated based on objects.
This type of command supports the exporting of all configuration scripts based on the object selected
by users
The exported objects include:
BSC data, including data on the BSC, equipment, transmission, and radio network
BTS data, including data on the BTS equipment, transmission, and radio network
NodeB and eNodeB data, including all data of site.
This type of command is generated according to the data in the planned area and is not related to the
configuration process.
This type of command is applicable to special scenarios such as initial network deployment or site
deployment.
Activation of Scripts

35/41
HUAWEI TECHNOLOGIES Co., Ltd. HUAWEI Confidential Page 35
Activation of Scripts
Activation Type
Run the Bulk_Configurationcommand in
batches. The efficiency for scripts to take effect is high.
The entire script needs to be modified after the
script activation fails.
Run the MML command one by one.
The efficiency for scripts to take effect is low.
The user interaction is large in number.
A single command is modified after the script
activation fails.
Activation Methods Timed activation: The configuration script is activated at the time specified by the user.
Stopped once an error occurs: The script activation is stopped immediately after an error occurs during a
command execution. In this case, the script activation resumes after the command is modified or skipped.
Skipping the error command: When error occurs during a command execution for activating the script, the
error command is skipped and the script activation resumes from the next command.
Pre-activation: The NE creates a simulative digital environment for the M2000 to perform the pre-activation
function. In this case, the M2000 can confirm whether data in the configuration files to be activated takes
effect.

Site DeploymentNetwork Expansion
and AdjustmentDescription
Network expansion and adjustment scenarios:Users export the currentconfiguration data (BSC: .ZIP file, by using the Web LMT (EXP CFGSYNFILE; eNodeB:
export from M2000). The exported data will be imported to the CME.
Users start the client software before using the CME to configure data.
Site deployment scenario:GU: The CME provides the basic unit of data configurationfiles (ZIP files) based on NEs. Users can import a ZIP file to create an NE. They can
also reconfigure an NE based on this file. LTE: create site using GUI or sumary.
Network expansion and adjustment:Users create an NE on the CME and import thecorresponding NE data obtained from the live network.
Users reconfigure the data of an NE by using the CME client. The procedure is the
same as that by using the integrated CME.
Users check the correctness of data through the consistency check function provided
by the CME.
After data configuration and data check are complete, users export the MML/XMLscripts for activating data on the live network.
Users activate data by using the Web LMT.
(Note: The frequency refarming scripts exported from the standalone CME must be
activated through the script executor provided by the integrated CME.)

Full Data XML Scripts Activation
Scripts generated by CME could be activated in many ways:
Remote Commissioning on the M2000;
Local Commissioning Using a USB Storage Device in Combination with Remote Commissioning
on the M2000; Local eNodeB Commissioning on the LMT .
Refer to base station Commissioning Guide
Operation Steps of Remote Commissioning on the M2000;
In CME, create site by GUI or summary importing;
In CME, Export Auto Deployment Configuration Data
After exporting from CME, user needs to create commissioning tasks, upload data, version
file etc.
On M2000: Start commissioning task. M2000 will commission NodeB/eNodeB automatically.
Full Data XML Scripts of NodeB and eNodeB could also be activated by MML:
On Web LMT, using command: DLD CFGFILE, ACT CFGFILE to download and activate full data
XML scripts
Configuration adjustmentthe incremental xml scripts generated by CME could not be activated
using Web LMT.

This is only for GU BSC and BTS . The incremental scripts for
NodeB and eNodeB are XML file which could not be downloaded
and activated by MML commands. Batch Processing
Scripts are executed through the Batchwindow on the WEB LMT.
Multiple execution methods are provided for a better man-machine
interaction.
The efficiency for delivering scripts to take effect is low.
Batch Configuration
Scripts are delivered in batches by running the RUN BATCHFILE
command on the WEB LMT. The efficiency for delivering scripts to take effect is high.
Script Executor
Scripts are uploaded to the script executor provided by the integrated
CME.
The script executor is used in the frequency replanning scenario and
the method for checking commands in the scripts is different from that
in the batch configuration and batch processing.
Consuming Time in Typical Scenarios
4489 scripts are executed during the swapping of five BTSs, including
adjustment of network optimization data.
Based on the preceding condition, it is calculated that the swapping of
50 BTSs takes about two hours and six hours respectively in batch
configuration and batch processing modes.
