Reply To: SDCCH and TCH DROP in Ericsson network


Hi Monty,

Is your drop reason SS on UL, DL or BL?

If your frequency plan is OK (as well as Frequency Hopping parameters – if used)then probably the bad quality can be due to low Signal Strength which may be a result of coverage issues.

Hardware problems may be a cause to the bad quality drops experienced.

The solution to such problems may likely involve antenna physical parameters reviews including re-orientations, height reviews as well as tilt changes (depending on site location-urban/rural).

For the case of low UL SS drops you may need to boost your UL SS with a TMA.
