Some operators have recently started to employ Anti-SoR (Steering of Roaming) practices. Anti-SoR is defined as “any technical network-based methods that can effectively frustrate, counteract or undo the effect of SoR when applied without the consent or participation of either the Roaming Subscriber or the HPMN Operator” (BARG BA.30).
The Starhome® Anti-SoR Detector™ solution allows mobile operators to detect potential anti-SoR activities used by visited network operators on outbound roamers. The solution provides the operator with anti-SoR focused alarms and comprehensive anti-steering analysis reports enabling further investigation of the potential “violator.”
