A lawful interception provisioning function, LIPF () and a system information retrieval function, SIRF (), communicate with each other via the X1 and X2 protocols. The LIPF () obtains, from the SIRF (), information pertaining to a network function, NF(), which is an instance of a virtual network function, VNF, in a telecommunicationnetwork (), where said information is unrelated to any LI target and any task associated with a point of interception, POI (), in the NF ().

Obtaining information pertaining to a network function in lawful interception

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

This disclosure relates to a method Sand a device for correlating in a Lawful Intercept Mediation system, LIMS, received Intercept Related Information, IRI, and, Communications Content, CC, data packets of a 5 targets lawfully intercepted session for deliverance over HI2 and HI3 interfaces, respectively, by means of a session-specific Correlation Identification Number, CIN.
