1)

Remote Electrical Tilt (RET)

1) How to check RET values: Write “RTRV-RET-INF” in command line and then click on “Execute” option. 2) Note: b)

a) No need to fill any values

appeared after selecting the command.

In Response Window :

Connect_Bord_ID represent L9CA card; 0 means first L9CA card just above the UAMA Card . Connect_Port_ID (0,1,2) represents the port sector on the Card



b) How to Change RET Values: Write “CHG-RET-INF” in command line and values before Connect_BOA

= 0

click on “Execute” option. (for first L9CA Card)

Connect_POR=0/1/2 ALD_ID

=

0

ANT_ID=1 Remember:

Tilt = Value in degree * 10.

For Example: if value in degree=2, Then Tilt = 2*10 =20 RET Degree.


fill

following


2) Physical Cell ID (PCI)

1) How to check PCI values: Write “RTRV-CELL-IDLE” in command line and then click on “Execute” option.

Note:

No need to fill any values




2) How to Change PCI Values: Write “CHG-CELL-IDLE” in command line and values before

Remember :

fill

following

click on “Execute” option.

A) SON ANR function should be off before executing the command. B) Sector should be locked before executing the command.

Cell_Num =0

andPHY_Cell_ID = Enter Required Value

and

then Click on “Execute”.

Cell_Num =1


and


Cell_Num =2


and


Note:Cell_Num = 0,1,2

represents


sector 1,2,3


3) MIMO Configuration (Mode & Type)

1) How to check MIMO Configuration: Write “RTRV-DL-SCHED” in command line and then click on “Execute” option.

Note:


10 | P a g e NEO eNB Part (R4G Project) © SAMSUNG Electronics Co., Ltd.



2) How to Change MIMO Configuration: Write “CHG-DL-SCHED” in command line and following values before

fill


Cell_Num =0

and

DL_MIMO_MODE = TM3 or TM4

and


Cell_Num =1

and


and


Cell_Num =2

and



and



4) Tracking Area Code (TAC)

ID

1) How to check TAC ID : Write “RTRV-DL-SCHED” in command line and then click on “Execute” option.

Note:





2) How to Change TAC ID: Write “CHG-CELL-INF” in command line and before

fill

following values


Cell_NUM = 0/1/2 Cell_Size = Very Small,Large etc. Tracking_Area = Put required TAC Note:

In case if we are changing TAC the same should be changed in MME also.



5) Check Alarm List 1) How to check Alarm List : Write “RTRV-ALM-List” in command line and then click on “Execute” option.

Note:





6) RRH

Lock/UnLock

Select eNB SAP ID as mentioned below and right click on mouse a table will open in which a option called “Administrative State” will appear . Click on Locked in order to off the RRH and Unlocked in order to On the RRH as mentioned below.



7) SON ANR 1) How to check SON ANR : Write “RTRV-SONFN-CELL” in command line and then click on “Execute” option. Note:





2) How to Enable SON ANR : Write “CHG-SONFN-CELL” in command line and drfine following parametrs before


CELL_NUM = 0/1/2 ANR_ENABLE = Auto



8) EARFCN

1) How to check EARFCN for UL & DL : Write “RTRV-EUTRA-FA” in command line and then click on “Execute” option.

Note:





2.1) How to Change EARFCN for UL & DL : Write following command “CHG-EUTRA-F A” in command line define following parameters before execute the command.

a) CELL_NUM = 0/1/2 b) FA_INDEX = 0 (always) c) EARFCN_UL & EARFCN_DL : put decided value Note: after execute 2.1 go to 2.2



2.1) How to Change EARFCN for UL & DL: Write following command “CHG-CELL-IDLE ” in command line define following parameters before execute the command. a) CELL_NUM = 0/1/2 b) EARFCN_DL = Put decided value c)

EARFCN_UL = Put decided value



Part-II (Checks During SCFT)

1.

Smart Scheduler On/Off.

2.

OCNS Testing During SCFT

3.

eNB Internal Neighbour Relationship



1) Smart Scheduler On/Off. How to OFF Smart Scheduler : a)

Write “CHG-SCHRSERV-INF” in command line and Select “Administrative = schrlocked” then click on “Execute” option



b)

Write “CHG-CELLSCHR-CONF” in command line and Select “CELL_NUM=0/1/2 ART_CELL=False” then click on “Execute” option.


&SM


2) How to On Smart Scheduler :

a)

Write “CHG-SCHRSERV-INF” in command line and Select “Administrative = schrunlocked” then click on “Execute” option



b)

Write “CHG-CELLSCHR-CONF” in command line and Select “CELL_NUM=0/1/2 SMART_CELL=True” then click on “Execute” option.


&


2) OCNS Testing

1) OCNS Loading : Write “Test-OCNS” in command line and define following parameters

a) SUB_CELL_NUM = 0/2/4 b) Modulation

= select decided value

c)

= select decided value


Cell Load


2) Terminating OCNS Testing :Write “Term-Test” in command line and define INVOCATION_ID mentioned below.

INVOCATION_ID = 0/1/2 + Execute



3) eNB Internal Neighbour Relationship

Step-1:

Select “Configuration”


and then go to “Neighbour” option


Step-2: b) c)

a)

Select Target eNB

Check Target eNB SAP ID is appear below “NeighbourRelation Info”. Go to “CELL_NUM” and select cell/Sector



Step-3: Let us consider we select sector-0 then we can see that the remaining sectors are appearing as aneighbour of sector-0 in “Target_Cell_Num”
