LAWFUL INTERCEPTION IN NETWORK SLICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18248901 titled 'LAWFUL INTERCEPTION IN NETWORK SLICES

Simplified Explanation

The abstract describes a method for providing lawful interception (LI) in a radio communication system with network slices. The method involves a broker LI provisioning function (bLIPF) connected to an LI centralized function (LICF) and at least one slice LI provisioning function (sLIPF) implemented on one of the network slices.

  • The LICF determines if a party of a network service has the LI target identity.
  • If the LI target identity is detected, the bLIPF conveys the LI target identity to the sLIPF.
  • The sLIPF activates a point of interception (POI) associated with or embedded in the network function (NF) to intercept data.

Potential applications of this technology:

  • Law enforcement agencies can use this method to intercept data in a radio communication system with network slices.
  • Telecommunication service providers can comply with legal requirements for lawful interception.

Problems solved by this technology:

  • Ensures compliance with lawful interception requirements in a radio communication system with network slices.
  • Provides a streamlined method for activating interception points in network functions.

Benefits of this technology:

  • Enables efficient and effective lawful interception in a complex radio communication system.
  • Reduces the complexity and cost associated with implementing lawful interception in network slices.


Original Abstract Submitted

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.
