3G / 2G
1

Hello everyone,

We are having zero call issue on a 3G cell. Although all jumpers connectors rectified and replaced. Yet the cell is not picking up proper traffic.

What can be the issue?
And is it RF related or operational problem

2

Is it new cell?

3

PS traffic is also zero??

4

If so, check with MSC whether Cell is created or not

5

Is there any hardware alarm on the site and also check the vswr values if it’s high on the said sector. Sometimes it get high and won’t show alarm

6

Yes it is zero

7

No alarms and no hw issues. All other hw replaced except for RRU

Vswr is also checked and its normal

8

Verify core end defination

Ok… how many sectors are affected? If only 1 or 2 then u can try to swap the mrru board with the good mrru board on site. I suspect faulty mrru board on the affected cells

Check if the Ci is defined from the core

We are having zero call issue on a 3G cell

Is this a new site? Has it been carrying voice traffic before and suddenly stopped or it has never carried traffic at all?

12

Not a new site. But not carrying for sometime like few months. Dont have the exact history

Then try this method. But Someone has to goto site to work with you on this.
