IMSI pillar

Allows, observes or restricts subscriptions by IMSI, by list or by operator range (MCC-MNC). It is combined with the IMEI and the MSISDN through the IMEI–IMSI–MSISDN link.

What Sx-EIR does with the IMSI

Every query receives the response set by the operator rule, applied and recorded by Sx-EIR. Each action is applied by an available module, added according to the project scope.

Sx-EIR module: IMSI blocking and control Solution: Roaming and out-of-agreement ranges
Regional case

IMSI blocking in permanent roaming

Context

Mobile operator in the Andean region with foreign subscriptions in permanent roaming that occupied its network without a roaming agreement with the operator.

ATC's intervention

ATC put into production IMSI blocking and observation on Sx-EIR, by list and by operator range (MCC-MNC).

The ROAM-GUARD function extends the view to all foreign IMSIs, by country and by agreement.

Result

The operator decides in the network which foreign subscriptions it serves. The analysis showed that most of what was blocked were Internet of Things (IoT) modules and trackers, information that guides the local offering of machine-to-machine (M2M) services.

Technical dossier under confidentiality

Configuration, interface and deployment detail, in a document for your team

Configurations, interface requirements per module, reference architecture, sizing, the migration plan and the compliance table for tender pre-qualification are delivered in a dossier under a confidentiality agreement, after a first conversation with the ATC team.

Next step

Data is processed on the infrastructure the operator designates, under its control.

ATC reviews the platform the operator prioritizes and proposes the appropriate configuration. Sizing and review are provided at no cost.

  • Review of the platform and the network interfaces
  • Sizing according to the operator's infrastructure
  • Staged proposal: module, platform or delegated operation
