layer of the network and is the core of Huawei

Centralized OM

multi-mode RAN integrated configuration solution. The CME supports the typical scenarios of the

M2000 server

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.

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.

Current Disadvantages and Improvement Plan 

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.

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.

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.

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.

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. Neighboring cell configuration express

Frequency Adjustment 

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
