The following clauses describe the high-level functional architecture for LI for 3GPP-defined services and network technologies. It describes the architectural elements necessary for LI, their roles and responsibilities, and the interfaces and interactions between them.

Clauses 6 and 7 of the present document describe how the LI for various 3GPP-defined network technologies and services are realised within the generic LI architecture, including associations of LI architectural elements with the network functions involved.

Not all LI architectural elements and interfaces are used in all network technologies and services.
