Sweden is mecca of network sharing

• Someone else operates part of your network

• Several management systems

Hierarchical structure only possible

with IM enrichment

• Sites, sectors and repeaters are not available in CM

• Cn-Operator is not available in IM

• Think about required drill-down and roll-up scenarios

• Multivendor HetSite > Duplicated HetSite

IM attributes also available in

Calculation Palette

Use Cases

1. Sector Hierarchy: Aggregate carriers (cells) cover same direction,

better GIS presentation. A new level of drill-down, roll-up.

2. Site Hierarchy: Direct and indirect drill-down and roll-up across co-located

technology and vendor.

3. Ad-hoc Reporting: Easy to directly filter IM attributes in NE palette, less

need for Network Area.

4. Management Report: e.g. How many LTE900 cells/sites in Malmö passed

acceptance before March 2015.

5. Discrepancy Discovery: CM vs. IM reports (next step is KPI-alarm)

6. Complex KPIs: IM attributes are available in calculation palette. Complex

KPIs can be defined with IM attributes.

Challenges

• What should I export?

• Units, format should be clear

• Required drill-down and roll-up scenarios should be defined in requirements

• You will find data inconsistency in IM

• In case of conflict which attribute is master IM or CM?

• Trade-offs: Enrichment needs HW resources. Some preparation may be

needed for efficiency.
