OtoU & UtoO HO Received Level Thresholds

[justdream]

Dears,

What's the meaning of both parameters as I'm confused about it
OtoU HO Received Level Threshold
UtoO HO Received Level Threshold

[justdream]

Dears,
Could you help please
what to do to puch traffic from OverLaid to Underlaid using above mentioned parameter??

[gunpowder]

you can by these two parameters control levels in underlaid and overlaid layers for example GSM(underlaid) and DCS(overlaid)
to push traffic to GSM (underlaid)
* Set OtoU to Lower Level for example -90 dBm (20)
* Set OPTILAYER to sysopt
* Set OPTILEVTHRES wich control target layer at handover to higher levels 30 for example
If levels is lower than 30(-80dbm) it will go to underlaid

Parameter description
Preferentially assigns channels on the overlay when the uplink receivelevel on the SDCCH is no smaller thanAssign-optimum-level Threshold and the TA is smaller than TA Threshold of Assignment Pref; otherwise, assigns channels on the underlay to ensure successful channel assignment.

You can use also Traffic Load switch/Quality Switch between Overlaid and Underlaid
But just take care that if all switches are on the will work as the following
OR condition from OtoU
And conditon from UtoO
