Passing through mediation platform and convert the data for further analysis through Handover Interface (HI) before reaching EDDC for further packet analysis Router/IAD

7. IMS IP packet/SIP Router/IAD USER ANALYSIS USER Router/IAD Target Edge Router SGIM IP Packet/SIP Data Packet Captured through Telco IP Switch EDDC LEA side Telco side Core Switch Edge Router (application layer) (media layer) E-Detective E-Detective Directly capture IP data packets from both application or media layers of IMS/all IP networks. So it is not necessary to pass through mediation platform. It’s predicted that this will be the future trend for all Telco operators CMS (session layer)
