SYSTEM AND METHOD OF IMPROVED LAWFUL INTERCEPTION OF SEAMLESS DATA SESSION CONTINUITY ACROSS HETEROGENEOUS NETWORKS

摘要

A method and system for providing lawful interception continuity across heterogeneous communication networks for an ongoing data session is disclosed, The method comprises: receiving one or more first data packets associated with an ongoing data session from a source communication network; detecting a handover of the ongoing data session from the source communication network to a destination communication network; receiving one or more second data packets associated with the ongoing data session from the destination communication network in response to detecting the handover of the ongoing session; maintaining continuity and sequence of the first data packets and the second data packets associated with the ongoing data session; and delivering the first data packets and the second data packets associated with the ongoing data session as the lawful interception data to a law enforcement agency.

1. A method for providing a lawful interception continuity across one or more communication networks for an ongoing data session, the method comprising:
receiving, by a session continuity server device, one or more first data packets associated with the ongoing data session from a source communication network; detecting, by the session continuity server device, a handover of the ongoing data session from the source communication network to a destination communication network; receiving, by the session continuity server device, one or more second data packets associated with the ongoing data session from the destination communication network in response to detecting the handover of the ongoing session; maintaining by the session continuity server device, continuity and sequence of the one or more first data packets and the one or more second data packets associated with the ongoing data session; and delivering, by the session continuity server device, the one or more first data packets and the one or more second data packets associated with the ongoing data session as the lawful interception data to a law enforcement agency (LEA).
