Is there something for Power Congestion

[Tomas Delgado]

Hi there, does someboy know a effective solution for power congestion that is not one of the following:
-New site
-New carrier
-Adding a cell to the site( from 3 - 4/5/6)
-Reduce PCPICH power (because you dont want to reduce pcpich coverage)
-Increase BLER Target
-Modify Min and Max RL power per service.
-Service based handover
-DL RAB reconfiguration based on congestion or TVM.

Thanks

You had mentioned all the solutions

[Tomas Delgado]

Is there some feature or procedure?????

Piss customers off so they won't be ones again, then no congestion.

If you have overlapping coverage you may try moving traffic to other neighbor cells via qOffset2sn or if you have additional carriers check your traffic balance, but as mention by mostly you listed all solutions.

I had used PwrAdm up to 90 and works fine, and drop calls increase but not that much.

The only problem with setting pwradm to 90 is that you can effectively disable soft congestion depending on your pwroffset. Remember pwradm+pwroffset (p7) must be lower than 100, unless you are trying to maximise the site for revenue.....Just something to consider....

Ok guys, lets put them in chronological orden supposing that the operator doesnt have the budget and besides all theyre miserly, i put my idea an at the end we can have an order of implementation based on cost, assume you just want to apply a solution that only affects the cell not the entire RNC and that cpich power reducing is not possible.
1.-DL RAB reconfiguration based on congestion or TVM.
2.-Service based handover
3.-Modify qOffset2sn
4.-Modify Min and Max RL power per service.
5.-Blast power admision control
6.-Adding a cell to the site( from 3 to 4/5/6 cells)
7.-New site
8.-New carrier
Vendors can implement some feature or algorithm to help this, i mean like the 1st step to aliviate only power congestion.

Currently how many watts per cell?

You can try to use MHA.

[Tomas Delgado]

Well, lets say not a mature network but definately not a recently deployed. You got the basics, one carrier and only 20W Radio units per cell. Its intersting what you propose, but it reminds me the case of using the other 20W of the radio units that have dual band capacity but for the same band, i mean able to transmit 2 carriers in one frequency lot like 850mhz. As far as i remember its clearly noted in one book that this can only works in environments that can handle bigger mapl, like rural scenarios. Also i have tried that in a urban , sub-urban scenario and the results are almost null. So with MHA you would enhance coverage more than capacity. Explain it a little more.

If your network is young, you can try modify Cell Individual Offset parameter for carrier only primary traffic one or two radiokink and save power.
