Within Self-Organizing Networks (SON), the Cell
Outage Compensation (COC) functionality is one of the most
important use cases in Self-Healing in mobile communication
networks. The state-of-the-art has proposed different COC techniques,
each of them to be indistinctly applied to all cells
in outage. Conversely, this paper presents an important improvement
of the COC function by adapting different COC
strategies to different cell outage situations. With this objective,
a novel COC methodology is proposed. When a cell outage
occurs in a network, a detailed analysis of the faulty situation
is carried out. The result of this analysis allows to classify the
degradation produced by the cell outage in the neighboring cells.
Depending on this degradation, different COC algorithms should
be applied to each affected neighboring cell. In addition, as
another contribution, some COC algorithms based on handover
parameters modifications have been applied to a cell outage
compensation problem. Results have shown that, by adapting the
strategy to the outage impact on neighboring cells, the proposed
method outperforms classic strategies.
