A service interruption manager function, SIMF, receives information that indicates that lawful interception, LI, service interruption associated with an LI task has occurred. Based on the received information, a determination is made of a status regarding the LI service interruption associated with the LI task, for example a determination whether the LI service interruption associated with the LI task has a current status that is any of: terminated, ongoing or initiated. A message is then transmitted, to a delivery function, DF, via an HI2 interface, the message comprising at least the determined status regarding the LI service interruption.

Managing service interrupts in lawful interception

Methods and network devices implement a lawful interception (LI) trigger control function as an LI target handler and a modified trigger control function. A generic LI triggering interface enables the modified trigger control function to query the LI target handler regarding whether entities using a network function instance are in a target list. The LI target handler has to meet the LI security requirements, but the modified trigger control function does not have to meet such requirements.
