The measurement values are computed by OsmoBTS. The raw values are
paseed from the BTS-specific part (osmo-bts-trx in your case) via the
L1SAP MPH_INFO indication (sub-type PRIM_INFO_MEAS) to the common part
in src/common, where measurement.c is performing the bulk of the computation.
The values are then reported on Abis every SACCH multiframe as part of the RSL
MEASUREMENT INDICATION messages to the BSC, which uses them as input for
e.g. handover decision making.
Regards,
Harald
