H  Location only warrant |R13|Word‑p. 362

H.1  General |R14|

The following describes the information that is delivered for authorization in those countries that allow authorized Lawful Interception (LI) for location scenarios.

H.2  Location only warrant |R14|

The ADMF provides the network and/ or LI LCS Client to collect location IRI against a target with a specified periodicity. The target may have several interception invocations with multiple LEAs. For an Authorization for location reporting, all other IRI's not associated with Location is filtered. For example if a target places a voice call, new location information is now available to be sent to the LEA with a location authorization, that location data, and only the location value can be sent to the LEA, any record of the event (call start and other associated event information) is not be sent. Other LEAs may have a warrant for the Voice Services, and they will get the associated IRI. The invocations of elements to be captured can be sent to the DF and/ or the MF can filter events not required for the Location Authorization

The ADMF provides the network and/ or LI LCS Client to collect the immediate location of a target. The target may have several interception invocations with multiple LEAs. For an Authorization for Immediate location, all other IRI's not associated with Location is filtered.
