Editing My 5G lawful interception notes (section)

== CC ==

'''SMF/UPF'''

The CC-POI present in the UPF generates the xCC from the user plane packets and delivers the xCC (that includes the correlation number and the target identity) to the MDF3.

'''IMS Media Function'''

The IMS-based services are determined based on the deployment option, the network configuration, LI service scope and the IMS session including the roaming scenarios.  Network functions that handle the media are referred to as '''IMS Media Functions''' and IMS Media Functions that act as CC-POI generate the xCC.

'''MMS'''

The MMS xCC is generated when the CC-POI in the MMS Proxy-Relay detects that CC related to an MMS message is either received from the target, sent to the target, or stored on behalf of the target.

'''PTC service'''

The CC-POI present in the PTC Server shall generate xCC.
