intracell_HO_allowed

El Alish,

I forgot about the applicability of this parameter. I could check on monday, but perhaps you can get your answer if you check this parameter definition ? (in NPO or in the OMCR)

Otherwise, you’ll have to wait monday 🙂 Or… you could just try it out, and see if the interzone HO still occur when it’s disabled.

AliAsgher, basically the question is : does this parameter control the interzone HO as well ? (cause 10, 11 and 13)

dear Pix,
i already check the OMCR before asking here, it said it controls the intacell HO.
so i still dont understand this parameter controls the HO from i.s GSM to DCS on the same sector, or the HO between different TRX’x on the same band on the same cell.

if its like the second case, what about hopping ??? the call is on the TS that hops between different TRX’s.

If a cell is in non-hopping mode and is on a TRX which has a frequency which is interfered, it could perfom an intracell Ho to another TTX of the same cell (It monoband cell).

In principle then when you are in nob-hopping, you should have ho-intracell enabled, to perform an HO to another TRX (and hence frequency) when a frequencey is interfered.

In hopping mode (SFH or BBH), because of the constant change of frequencies, bline intracell HO is not necessary.

I have observed that sometimes when you have a faulty TRX there is an increase in intracell HOs, and they are mainly of type “CHO_UL_Interference” even if you are in hopping mode.

Bottom line, if you are sure of your equipment, then for hopping, disable intracell HO (to decrease the probablity of making a drop, etc.) and for non-hopping, enable it.

HO_INTRACELL_ALLOWED does not affect specific concentric / multiband cell handovers (cause 10, 11 and 13).
Also, It doesn’t affect TFO HO nor PS->CS Zone HO.

Yes.
