Abstract: 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.

Abstract: A method for providing lawful interception, LI, in a radio communication system (500) with network slices, NSs, (520, 530, 540). The method comprises: providing a broker LI provisioning function, bLIPF (508) connected to an LI centralized function, LICF, (506), and to at least one slice LI provisioning function, sLIPF, (528, 538, 548) 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, (522, 524, 526, 532, 534, 536, 542, 544, 546) 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, (522p, 524p, 526p, 532p, 534p, 536p, 542p, 544p, 546p) associated with or embedded in the NF to intercept data.

Abstract: Methods and devices provide lawful interception (LI) using slice-based mediation and delivery functions (sMDFs) and providing network slices configured for performing LI functionality as required. A network slice of a radio communication system is selected if configured to execute an sMDF. If a party to a service delivered using a network function (NF) implemented on the selected slice is indicated as being an LI target, then LI data intercepted from the NF is forwarded to the sMDF within the selected slice. The sMDF then reformats and transmits the LI data outside the network slice.

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.

Abstract: A fuel distributor for a multi-cylinder combustion engine with fuel-injection system, comprising a fuel flow divider having a tubular distributor housing and at least one fuel feed connection as well as at least one fuel return connection. The fuel flow divider has a number of first receiving holes which corresponds to the number of injection valves, and a second receiving hole arranged in the region of an end limitation of the distributor housing. In order to supply fuel to an internal combustion engine having at least two rows of cylinders, one fuel flow divider is used for each row of cylinders, the fuel flow dividers being developed in corresponding manner and being connected to each other in fuel-conducting manner by a connecting line and arranged in series. A pressure regulating valve is arranged in said second receiving hole of one of the two fuel flow dividers and a pressure test connection is arranged in said second receiving hole of the other fuel flow divider.
