BSC6900 Board Naming Improvement
New more boards to be selected, specification promotion, interface and transmission sharing etc. Board is named as physical type and logical function type, which simplifies the configuration
In BSS8.0, the operator should know detail meaning of each logical board. But In BSS9.0, the operator need just to know the physical type and logical function type, it’s easier than before.

BSC6900 Parameters & Documentation Optimizing
Parameter Presentation: Change from “BSC-BTS-CELL-TRX” to “each parameter listed one by one, but with
more powerful filter function” Parameter Name: 1 Optimize parameter name,2 Change the type of board naming to simplify
configuration , 3 Delete the unit information from parameter name to make more clear, for example: "Flex Abis Prior Choose Abis Load Threshold(%)"->"Flex Abis Prior Choose Load Thred“
Parameter Unit: Unified to national Unit, such as, Change the unit of parameter "Diesel Max Output Power" from "KVA" to "W"
Parameter Meaning: Re-organize and simply the description of parameter to make more easily understood
Default Value and Range: some changes because of specification promotion, such as “Cell ID” parameter
Parameters Added, for example, parameter “link bear type” of MTP3lnk to distinguish detail link bear type (MTP2 or SAAL)
Parameters Deleted, for example, parameter “communication mask” of table “fan attribute” is deleted because the fan configuration algorithm is optimized and the parameter will be no longer used
Documentation Adding corresponding relation description between counters/ parameters and features Optimized documentation improves troubleshooting efficiency

• OAM Solution BSC6900 LMT is based on web and doesn’t provide GUI-wizard-mode configuration features, which
are provided by CME, but MML and maintenance functions are still kept in web LMT. CME provides all the configuration features.
• Logical Function Domain CM configuration rules use python Separated fault and alarm design, alarm correlation Transmission pooling design, resource management optimizing
• Implementation Domain OMU OS: Newly-support Windows, simplified Linux OMU DB: Changed to MySQL Changes in the definition of Alarm and PM counters, some MML and configuration parameters are

Changes in MML & Parameters
• MML Changes in format and style: add a prefix G to RNP & RNO related MMLs, for example, “ADD CELL” in
BSS8.0 is changed to “ADD GCELL” in BSS9.0 Changes in definition, some MMLs are re-designed, for example, RNP & RNO data and BTS physical
device data are added together with MML “ ADD BTS”, “ADD CELL”, “ADD TRX” in BSS8.0, but RNP & RNO data and BTS physical device data can be configured apart with a series of MMLs, such as: “ADD BTS”, “ADD BTSTRXCARD”, “ADD GCELL”, “ADD GTRX”, “ ADD CELLBIND2BTS”, “ADD TRXBIND2PHYBRD”. This will also result in difference in configuration steps and configuration flexibility.
MML deleted: for example, “MOV BTS” in BSS8.0 is deleted in BSS9.0 because it can be replaced by another MML “ MOD BTSCONNECT”
MML added: for example, “CHK BTS” is added to verify specified BTS data in advance if it is not activated
Changes in command groups which MML belong to: for example, command group of “STR BTSLOG2OMU” are changed from "Advanced BTS Maintenance” in BSS8.0 to “BTS Management”. This will also lead to changes in user right after upgrading BSS8.0 to BSS9.0 except administrators. The possible situation are listed below:
No change in user right, such as administrator user Enhancement in user right, such as user group from “users” to “operators” Decline in user right, such as user group from “operators” to “users” If user group is “custom”, then the user group need to be re-configured after upgrading

handover Some useless counters are deleted Naming optimization for device or transmission counters Counters are packaged according to features and scenarios
Alarms Alarms are re-organized based on scenarios, alarm items and instances are reduced to
let the users to concentrate on root causes, so some alarms are added and deleted Some alarms are changed, such as name, location information, etc.

Changes in BTS Related Cont.– BTS Software Upgrade
• The particularity of BTS software upgrade from BTS8.0 to BTS9.0 compared with previous version upgrade is that BTS data should be converted at the same time when BTS software is upgraded.
Two custom-build ways to be provided if upgrade BTS software from 8.0 to 9.0
BSC-reset way: applicable to the scenario that all or most BTSs of one BSC need to upgrade software
Online way: applicable to the scenario that few batch BTSs need to upgrade software (It is recommended that the number of BTS be not more than 10 each time)
Notes: The change only happens when upgrading software from BTS8.0 to BTS9.0 but will not happen in later software upgrade, such as from BTS9.0 to BTS12.0, BTS12.0 to later version and etc.
