MML client

Gains The Web LMT is based on the Web without a

client. The 2G&3G local maintenance functions are

integrated, and thus the maintenance work of the BSC is simplified.

The CME, based on the unified NMS platform, supports multi-mode access and GBSS full configuration and provides the inter-NE management function.

Changes

The Web LMT adopts the Web technology, and the interface style is changed.

The graphical configuration function is provided by the CME and is further enhanced.

Some MML commands are optimized for the Web LMT.

For the comparison of the functions of the BSC6000 LMT with those of CME V200R009, see the following attachment.

CME Positioning

The CM Express (CME) is located in the OSS

layer of the network and is the core of Huawei

multi-mode RAN integrated configuration solution.

The CME supports the typical scenarios of the

GSM access network, such as initial deployment,

network expansion, BTS swap, and routine

configuration adjustment. CME V200R009 is the integration and

enhancement of the GBSS LMT and the GBSS

CME data configuration. For the GSM network, the BSC6900 that

cooperates with CME V200R009 provides the

GUI data configuration function. In the case of centralized management across the

entire network, the CME enhances the NE OM

efficiency and degrades the performance in

single-object configuration and resource

consumption.

CME Advantages

GUI enhancement The BTS creation wizard of the BSC6000 LMT is evolved to topology BTS creation, where the

GUI views of BTS networking, cell TRX, and timeslot occupation are added, and the BTS

creation and resource allocation are easier to perform.

CME Advantages (Continued)

Operation efficiency improvement Centralized network-level configuration:

Single-BSC configuration multi-BSC configuration

Single-BTS configuration BTS template and batch BTS configuration

The inter-BSC BTS swap is supported and the neighboring cell data can be adjusted automatically, thus

saving the time for creating the network optimization script.

The offline configuration takes effect dynamically, thus expanding the application scope of the offline

configuration:

The .dat file for LMT offline configuration can take effect only after the BSC is reset. Resetting the BSC

seriously affects the services.

CME offline GUI data configuration generates the MML script, which can be dynamically delivered and

take effect without a BSC reset.

The single-user configuration mode of the BSC6000 LMT is evolved to multi-user online configuration.

The data browsing and highly-efficient retrieving capabilities over the entire network are provided.

Security Planned areas can be configured with proper rights by setting user groups.

Before data activation, the data over the entire network can be checked; for example, the integrity,

redundancy, and consistency can be checked.

Parameter comparison: The data that takes effect can be checked against the template to verify the

configuration correctness.


The security of data configuration is improved, but the efficiency of configuration fine tuning is

affected.

In this version, the efficiency of batch operations is improved, but the configuration operations of fine tuning and

fast adjustment are not as simple as the operations on the original LMT version, where fine tuning and fast

adjustment are directly performed on the LMT. The new configuration process is as follows: Creating a planned

area -> Modifying/adjusting the configuration -> Exporting the script -> Using the script executor to deliver the

script. In this process, the security of configuration operation is significantly improved, but some operation steps

are added. Therefore, fine tuning is not as convenient as in the original LMT version, where fine tuning is directly

performed on the LMT and takes effect immediately.

Huawei recommendation: The MML commands of BSS 9.0 are significantly improved, and therefore the

adjustment of few parameters can be implemented quickly through MML command execution.

Improvement plan: The E2E data delivery process will be improved. Then, fine tuning and fast adjustment can be

supported, and the data can be delivered and take effect immediately.

After the OM focus is transferred to the upper layer, the usage habits of some functions are

changed. After the configuration function of the original LMT version is transferred to the upper layer, the single-point configuration and OM operation mode of the original BSC6000 LMT are changed, that is, some operations require interface switchovers. For example, after a BTS is added on the CME, you need to check the transmission status of the BTS through the Web LMT.

Improvement: The OM function on the M2000 will be further enhanced to make the configuration interface and

OM interface unified and make the OM work centralized.

Current Disadvantages and Improvement Plan


Configuring Area Management

Concept of the current area A current area is a network data mirroring area used to store

the configuration data of the existing network.

A current area is readable only and cannot be directly

modified.

For a network system, there must be a current area and there

is only one current area.

The current area can periodically/automatically/manually

synchronize the data on the existing network.

Concept of the planned area A planned area is a planned data area, which stores a copy

of the data of some NEs in the current area.

Different users can create their respective planned areas with

parallel independent configurations.

When a user completes the data configuration of a planned

area, the data can be exported to generate the script. The

script can take effect after being delivered to NEs.


Overall Work Flow

0. NE synchronization: Obtain the data from the existing network and

synchronize it to the current area. The current area is stored on the M2000 server. All users of the M2000 use the same current area.

1. Create a planned area: Copy the NE data from the current area. The planned area is stored on the M2000 server. Each user uses his/her own planned area(s).

2. Configure data of the planned area. Add, delete, or modify BSCs, BTSs, cells, or TRXs. Adjust parameters.

3. The script is generated, is delivered, and takes effect. Conflict detection: Compare the data of the planned area with that of the current area. If

any conflict occurs, adjust the data to eliminate the conflict to avoid script activation

failures. Generate the MML script. Use the script executor to deliver the script to NEs, and then the script takes effect.

4. Attribute Value Change (AVC) After the script is generated, the NE reports an AVC message to inform the change of the

data on the existing network against the data of the current area. After the NE data is changed in another way, the AVC message is also reported. Current area synchronization is triggered in quasi real time.

Data Flow

Three major network areas are the existing network, current area, and planned area.

Data flow exchange Planned area current area: The data of the planned area is modified and does not affect the data

of the current area. Planned area existing network: The changed data of the planned area takes effect on the

existing network through script generation and activation. Before the data is delivered, it does not

affect the data on the existing network. Existing network current area/planned area: If the configuration on the existing network is

changed, the change is updated to the current area but cannot be updated to the planned area. Current area planned area: Copy partial data of the current area to the edited area through

planned area creation/synchronization. Current area existing network: The current area is readable only and does not affect the existing

network.

Current Area Synchronization

Synchronization mechanism Full synchronization: All configuration data of NEs is

uploaded, and the uploaded data completely overwrites the

data of the current area. The history data of the current area

is not saved. Incremental synchronization: Only the changed data of NEs

is uploaded, improving the synchronization efficiency.

Usually, incremental synchronization is used. Incremental synchronization is supported since the

BSC6900.

Synchronization mode Periodical synchronization, automatic synchronization, and

manual synchronization are supported. The synchronization

of the current area is quasi-real-time. The CME implements automatic synchronization in the

following cases: After receiving the AVC message reported by the NE,

the CME does not receive another message in two

minutes. The BSC is created on the M2000 and the

synchronization is complete. The script data is successfully activated.

Current Area Synchronization - Demonstration

Manual synchronization Access: From the menu bar in the main CME

interface, choose Area Management > Current

needs to be synchronized, do not select Forced

synchronization of all objects; if all the data of

the selected NEs needs to be synchronized,

select Forced synchronization of all objects. Click Synchronize, and then the system starts

loading the NE data. Click Close to return to the main CME interface.

Periodical synchronization Access: From the main menu of the M2000

client, choose Maintenance > Task

Select CME Upload, and specify Task Name

and Run Type.

Specify Start Time.

Select NEs and click Finish.


Creating Planned Areas

Plan planned areas. Multiple planned areas can be created based on the

current area. Parallel configurations can be adopted to

construct a network.

The configuration conflicts among planned areas can be

detected only when the planned areas take effect on the

existing network. The conflicts may cause the planned

area to fail to take effect and may cause the data of a

planned area to overwrite that of another planned area,

affecting the running of NEs.

If the automatically allocated data is used for parallel

planned areas, the data must be planned to avoid

overlapping. For example, the BTS index and TRX index.

Create planned areas: Copy partial NE data of the

current area.

planned area to be created. Click OK, and then the planned area

is created. The planned area is automatically opened.


Configuring Data for the Planned Area

General configuration: A user can configure the

attributes of each object through the GUI general

configuration interface. General configuration

involves the following configuration views: Left tree: object tree view and transmission tree view Configuration area: device panel view and

configuration objects Topology view Batch modification view Configuration express view

Wizard configuration: A user can complete

complicated configuration tasks through the

wizard. Topology BTS creation Swap wizard Consistency check wizard

File import and export: This implements batch

configuration. Importing the negotiated data for BTS creation Importing and exporting radio parameters Modifying the cell attributes, frequencies, and TRX

attributes in batches

Device panel


Script Generation

The script can be generated in difference MML mode or full MML mode. Difference MML mode: The MML configuration script is generated based on the modification.

The script is generated based on the configuration operation record in the planned area of the user.

The script is consistent with the configuration procedure of the user.

Difference scripts are exported for multiple times for a same planned area. Each time, the most recent

modification is exported. That is, the difference script generated in the most recent time is the basis of

the next difference script to be generated.

All configuration operations are supported. It is recommended that this mode be used for the

scenarios such as parameter modification and radio network planning and optimization.

Full MML mode: The full configuration script is generated based on the objects. The configuration script of all the parameters involved in the objects that the user selects is exported.

– The exported objects include the following:

– BSC data, including BSC global data, device data, transmission data, and radio data

– BTS data, including BTS device data, transmission data, and radio data

The script is generated directly based on the data of the planned area and is not related to the

configuration procedure of the user.

Certain scenarios are supported. It is recommended that this mode be used in initial office deployment

or BTS creation.


Script Activation

Batch processing The batch processing command window on the Web LMT

can be used to run scripts. Multiple execution modes are available with good man-

machine interaction. The efficiency for delivery and effect taking is low.

Batch configuration Commands can be delivered in batches by running the RUN

BATCHFILE command on the Web LMT. The efficiency for delivery and effect taking is high.

Script executor The script executor in integration mode can be used to

upload scripts. Concurrent operations on multiple BSCs are supported. In the frequency translation scenario, the verification mode

of the commands in the script is different from that in the

batch processing or batch configuration scenario.

Time consumption in the typical scenarios The swap of 5 BTSs including network optimization data

adjustment requires a script of 4489 lines. Based on the preceding information, the swap of 50 BTSs in

the two scenarios takes 2 hours and 6 hours respectively.

Scenario Time Consumption

Batch configuration 647 seconds

Batch processing 1767 seconds


The CME provides the configuration data activation function. After the configuration data is

generated, the CME can deliver the configuration data to the existing network to implement

remote data activation.

BTS Creation - File Import Mode for Batch BTS Creation

In batch BTS creation, the hardware configurations of the BTSs are usually the same,

and the data configurations are similar or the same. Importing and exporting the BTS

negotiated data provides the capability of setting up a large number of similar BTSs

quickly.

The file data used for batch BTS creation is usually the network planning data, which

needs to be saved in the file format that the CME requires.

The file format for importing the BTS negotiated data and that for exporting the BTS

negotiated data are the same. The existing BTS negotiated data exported from the CME

can act as the basis. After modification, the BTS copy function can be implemented.

List of BTS negotiated data objects

The BTS negotiated data file contains the transport-layer data and

radio-layer data that are mandatory for BTS creation. For details, see

Application scenario Function description: You can modify information such as cell algorithm

parameter, TRX-level (including channel) parameters, frequencies, and

neighboring cells. Application scenario: To ensure the network quality and improve the

network performance during the running of the GSM network, you need to

continually adjust the network data. The CME provides the following modes to modify parameters:

Adjustment through the interface configuration express

This is applicable to single-parameter modification for a single object. Batch modification

This is applicable to change the same parameter to the same value in batches. Importing and exporting

GSM Network Adjustment - Modifying Cell Frequencies and Frequency Hopping

This table contains all the objects related to frequencies. Therefore, the objects in this table overwrite the existing objects in the system during import. For details, see the attachment.

If shared-channel interference or side-channel interference occurs in a cell, or the operator re-plans the network frequencies, you need to adjust the frequencies of the cell. The CME provides the interface-based adjustment and importing/exporting to adjust TRX-class attributes.

2G Cell Frequency


Neighboring cell configuration express Importing and exporting

GSM Network Adjustment - Modifying Neighboring Cell Relationship

The exported data contains the neighboring cell relationship and external cells. For details, see the attachment.

After the operation of a network starts, the network load and radio environment keep changing as subscribers increase. To ensure the proper performance of the network, you must take effective measures to check and adjust the neighboring cell relationship to guarantee normal handovers and the mobility of mobile stations. The CME provides the interface-based adjustment and importing/exporting modes.

The neighboring cell configuration express can use the template to create the neighboring cell relationship, and users can create templates. This improves the

configuration efficiency.

Right-click a cell and select Neighboring Cell Configuration Express. Then, the neighboring cell configuration express interface is displayed on the right, and you can configure the neighboring cell relationship of a single cell.

2G Radio Network Planning Data


The impacts of frequency adjustment are as follows: Frequency adjustment requires the BCC and NCC of the cell to change. Therefore,

the user needs to change the BCC and NCC values when adjusting frequencies.

Adjusting the hopping TRX frequencies or BCCH TRX frequencies resets the cell

with a latency of 10 seconds. That is, the BSC resets the cell 10 seconds after the

frequency adjustment. If the services of the cell are not handed over to another cell

in 10 seconds, the services of the cell are affected.

Adjusting the frequencies not related to frequency hopping does not reset the cell.

Currently, the CME supports the following frequency adjustment modes: Interface-based adjustment

Wizard-based adjustment
