Legitimate holder protection
The IMEI, IMSI and MSISDN are linked to protect the legitimate holder and preserve their number.
The demand on the operator
When an IMEI is repeated, a restriction requires verifying the link with the legitimate holder. Portability requires every MSISDN to be routed correctly.
ATC's response
Sx-EIR links the IMEI, IMSI and MSISDN, and authorizes or restricts their combinations with evidence and a legal basis; Sx-EIR One Control adds MSISDN Control and triplets. Sx-NpX maintains portability across every network generation.
How it operates in the network
Link
The module records IMEI–IMSI–MSISDN associations and their history.
Legal basis
Each restriction is activated with the evidence and legal basis the operator approves, with prior notice to the subscriber.
Portability
Sx-NpX queries the ported number database and links the ported MSISDN with Sx-EIR.
Results for the operator
- Legitimate holder protected when an IMEI is repeated
- MSISDN blocking orders fulfilled
- Portability in line with the regulator's framework
