Claim 18:
19. A system implemented in a network core of a fifth generation (5G) wireless network for cleaning up hanging lawful interception (LI) resources, the system comprising:
one or more processors;
a plurality of triggering functions in a network core of a fifth generation (5G) wireless network;
a data store including a data storage network function, the data store comprising a plurality of auditing records corresponding to the plurality of triggering functions, wherein each auditing record comprises a claimant attribute; and
instructions that are executable by the one or more processors to:
cause each triggering function among the plurality of triggering functions on the network core of the 5G wireless network to send an update request to the data store in response to being notified about a failed triggering function within the plurality of triggering functions, wherein each update request comprises a request to change ownership of an auditing record corresponding to the failed triggering function;
select a triggering function of the plurality of triggering functions as a new owner of the auditing record, the auditing record corresponding to the failed triggering function based on a match between the claimant attribute in the auditing record and a claimant field in the update request sent by the triggering function; and
cause the new owner of the auditing record to send at least one request to a triggered point of interception (POI) to remove an LI resource corresponding to the failed triggering function.
