VOICE OVER LONG-TERM EVOLUTION (VOLTE) CALL NORMALIZATION AND ALERT POLICY SYSTEM

机译:长期演进语音(VOLTE)呼叫规范化和警报政策系统

摘要

The present disclosure describes techniques that facilitate detecting a Voice over Long-Term Evolution (VoLTE) call request with a recipient call number that lacks a country code. The VoLTE call request may be initiated by a subscriber device while roaming in a VPLMN. Specifically, a Normalization and Alert Policy (NAP) system is described that is configured to analyze the VoLTE call request and determine an intended country code and adjust the recipient call number to include the country code. Further, the NAP system may analyze the adjusted recipient call number to determine whether initiating a VoLTE call in response to the VoLTE call request may trigger an alert condition. An alert condition may relate to determining that the VoLTE call request may initiate a cost-prohibitive VoLTE communication or that the VoLTE call request relates a fraudulent communication.
