=== 5.4.14	Lawful Interception Internal Query Response (LI_XQR) ===

Added in 3GPP TS 33.127 V16.6.0 (2020-12)

The LI_XQR interface is used by the IQF to send identifier association queries to the ICF and from the ICF to return identities associations to the IQF in response.

The following are examples of some of the information that may be passed over LI_XQR from the IQF to the ICF:
* Information relating to the type of query.
* Temporary or permanent identifier provided by the LEA.
* Other information associated with identifier required for localisation provided by the LEA.
**	Cell identity.
** Tracking area identifier.
* Time that identifier provided by the LEA was observed by the LEA.
* Location information request from the LEA for permanent to temporary identifier association.

The following are examples of some of the information that may be passed over LI_XQR from the ICF to the IQF:
* Information relating to the type of query being responded to.
* Temporary and permanent identifiers corresponding to identifier provided by LEA. 
* Identifier association validity start and end times.
* Location information.

NOTE:	The location information returned in the IQF response is the information associated at the time of the specific identifier association caching at the ICF.
