Conclusion • Connection to Pioneer OSS is extremely slow • There is massive missing NB on 2G adjacency while on 3G adjacency just having some missing NB.

• Significant KPI improvement of HO Success Rate for Pioneer OSS and

Valero OSS after massive missing NB addition in both OSS (illustration on slide: 11-12 & 30-31)
