1. A method for providing lawful interception, LI, in a radio communication system with network slices, NSs, the method comprising:
providing a broker lawful interception provisioning function, bLIPF connected to a lawful interception centralized function, LICF, and to at least one slice lawful interception provisioning function, sLIPF, implemented on one of the NSs;
receiving, from the LICF, by the bLIPF, an LI target identity according to a warrant, 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 that is to be delivered outside the one of the NSs.
