Abstract
Lawful interception (LI) of electronic communications includes receiving, by a triggering function (TF), a task request including a task identifier (ID) from a LI provisioning function (LIFP). The TF receives an indication of a protocol data unit (PDU) session establishment applicable to the received request, and then triggers (including a POI task ID) each point of interception (POI) applicable to the request. The TF receives a task response indicating a status of the task at the triggered POI. The TF reports, to the LIPF, a TF task issue request indicating the status, the TF task ID, the POI task ID, and a network entity ID of the POI.
