The heart and soul
of a cellular network is neighbor. And that’s the reason that we HOSR as one of
the major KPIs. Until now we are measuring HO with infamous intra-eNB and
inter-eNB HO KPIs. And in way its logical as well that whenever we integrate a
new site we need to measure its HO activity within the site and as well as to
its neighboring sites.
Now a days the major
issue is capacity and to meet capacity we often add carriers and take the
benefit of carrier aggregation as well to meet the capacity demands.
So the HO activity
is increasing exponentially due to multiple number of carriers (frequencies)
being transmitted from single site. And intra-eNB and inter-eNB HO doesn't
offer such granularity as they are much more equipment oriented.
And we cannot have
HO KPIs with every other neighbor in the form of a grid as well because every
single cell has hundreds of neighbor relations.
Since now we usually
add/delete frequencies in our existing sites and they stay within range that we
can view them in the form of a grid.
This Grid can be
used as a measure to evaluate traffic management settings and that alone can be
major reason to have this grid on your RF dashboards in addition to other
benefits you will be getting, like how good or bad new additional carrier
(frequency) is doing with existing carriers from mobility point of view. And
hence we can call it traffic management KPI as well.
We can have a couple of filters on top of this grid like one for HO related (like
preps/executions/execution failures) and other for geographical area related
(like cell/sector/site/cluster/market/region/nationwide level)
