Make interference measurement parameters configurable
According to 3GPP TS 45.008, the BSS shall monitor the levels of
interference on its IDLE traffic channels. The actual measurements
are performed in the BTS and then reported to the BSC over the
A-bis/RSL link(s) in RF RESource INDication messages.
3GPP TS 45.008 defines the following measurement parameters:
* Intave: Interference Averaging period (see table A.1),
* Interference level Boundaries (see table A.1).
Both parameters are sent to the BTS over the A-bis/OML, and can
now be configured via the VTY interface. Only those BTS models
which 'speak' the OML protocol defined in 3GPP TS 52.021 will
actually get the configured parameters, others will keep using
the hard-coded parameters.
