Lawful Interception (LI) implementation guidance; LI for ID association caching
The present document provides architectural diagrams, conceptual scenarios, flow-diagrams, examples, and other background information which can be useful to implement the LI functions defined in TS 33.126 [2], TS 33.127 [3], TS 33.128 [4] and TR 33.928 [5].
The present document that covers illustrations of ID Association Caching focus on the capabilities used to provide the temporary identity to permanent identity (and vice-versa) associations known to the CSP network. The illustrations include the architectural concepts and few examples of use-cases encountering various timing scenarios.
