A method for providing lawful interception, LI, in a radio communication system () with network slices, NSs, (). The method comprises: providing a broker LI provisioning function, bLIPF () connected to an LI centralized function, LICF, (), and to at least one slice LI provisioning function, sLIPF, () implemented on one of the NSs; receiving an LI target identity, if the LICF determines that a party of a network service provided using a network function, NF, () running on the one of the NSs has the LI target identity; and conveying the LI target identity from the bLIPF to the at least one sLIPF, wherein the at least one sLIPF activates a point of interception, POI, () associated with or embedded in the NF to intercept data.

Lawful interception in network slices

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.
