Abstract

   This document provides use cases for the IP-based communications
   security using Interface to Network Security Functions (I2NSF). The
   use cases in this document cover the detection and prevention of the
   illegal authentication, call of VoIP/VoLTE and spam message.

1. Introduction

   As VoLTE is a crucial service for telecommunication operators, it
   becomes more important to provide secure voice and messaging
   communication services. VoLTE and VoIP are based on IP, attacks such
   as compromising the telephony application or re-routing the IP
   signal can be happened.

   This document describes IP-based communications security use cases
   for Interface to Network Security Functions (I2NSF) such as VoIP,
   VoLTE and messaging service.

2. Conventions used in this document

   VoLTE: Voice over LTE

   SND: Software defined Network
