How we do Re-Homing?
1- Halt the Cells 2- Disconnect Cells from the old TG 3- Move the Cells definition to the new BSC4- On the new BSC , create a new TG 5- Connect the TG to the Cells and the New Transmissions6- Activate the Cells 7- Delete the Old TG from the Old BSC
Steps to do that
First we will receive the data for the site after Re-HomingFor example: We wantt to move the site CAI1700 from BSC 1 to BSC 9 and the new Transmission is 64RBL2
1- Get the complete data of the site a. Current BSC, Current Transmission, (From the Report then compare to the data in the System)Assume that the report said that the site is on BSC 1, TG-12, To check:On BSC 1rxtcp:mo=rxotg-12;(Get information about the Cells name that connected to the TG 12)
b. Get Site Configuration, and TRU Positions.
On BSC 1rxcdp:mo=rxotg-12; (Get the number of TRUs)rxmop:mo=rxotx-12-0&&11; (Get the Band that the TRU is working on it)
Or we can get this information from the report.
2- Halt the cells and disconnect them from old TG , and disconnect them from the TRUsa. rlstc:cell=1700e,state=halted;b. rlstc:cell=1700f,state=halted;

c. rlstc:cell=1700g,state=halted;d. rxbli:mo=rxotg-12,subord,force;e. rxese:mo=rxotg-12,subord;f. rxtce:mo= rxotg-12, cell=1700E, CHGR=0&1; g. rxtce:mo= rxotg-12, cell=1700F, CHGR=0&1; h. rxtce:mo= rxotg-12, cell=1700G, CHGR=0&1; i. rxmoc:mo=rxotrx-12-0&&-11,cell=all;j. rxmoc:mo=rxotx-12-0&&-11,cell=all;
3- Use the CNA to move the cells to the new BSC
First Create A Planed Area For moving the Cells
Right Click on the Desktop then Configuration Confiner GSM Radio network Cellular Network Administration
Then Click File New Area Planed Area Type Planed Area Name (ex move_cells)
Then Click View Cells Internal All
Then Click Highlight the Cells we need to remove to new BSC
Double Click On the Cell , then Change The LAC value to the New Value
Then Click Edit Move Cells in the popup window Choose “Target BSC” Move
Then Activate the Planed Area
Load the planned area to the network:
Click File New Job Update Job
A new window wills pop-up asking for Update Job Name. Any name can be used
Select “YES” for Fallback AreaSelect “Continue” for Action on Fault
Then click the “NEW” button to start executing the planned area.
Update Job checking

Click File Jobs My Own
Select the Job Name you created (move_cells) it should be in “ACTIVE” status.When the job is finished you should either see “COMPLETED” or “FAILED”
4- On the New BSC Create a TG, according to the new Transmission value (RBL2), and connect the cells to it. You can use any CDD and use the right template to create the Script of the new TG 5- Delete the OLD TG Form the old BSC
On top of it:I like to do everything before actual reparenting. So when we execute procedure,we minimize possibility for error or delay. Normally, we do 300 TRUs per hour.
For every cell prepare new name, NCC and LAC.Use CNA to copy, rename cell in the process.In planned area, halt cells (so they are defined halted), change NCC and LAC.Then update only traget BSC.
By adjust/cna_export and few ****ed scripts fix neighbor relations - as there is separate LAC and NCC, there is no disambiquity.And fix those CS handover parameters CNA is getting wrong for 15 years!Do not forget VLRs!
Then slowly define TGs, connect CHGR and cells, check all definitions....No hurry, no network impact.
For real reparenting, just halt cells in old BSC, reconnect Abis and activate on new BSC.Some handovers might fail, but who cares at 02 o'clock..Thus, cell downtime is minimal, and never for whole area.
Afterwards, clean up old definitions from old BSCs and VLRs.
