Cleaning up hanging lawful interception resources from a triggered point of interception when a triggering function fails

A method for enabling hanging lawful interception (LI) resources to be cleaned up, the method being implemented by a triggering function that belongs to a triggering function set that comprises a plurality of triggering functions, the method comprising:

• receiving notification about a failed triggering function in the triggering function set;
• sending, in response to the notification, an update request to a data store that comprises a plurality of auditing records corresponding to the plurality of triggering functions, wherein the update request comprises a request to change ownership of an auditing record corresponding to the failed triggering function;
• receiving, in response to sending the update request, an indication that the triggering function has been selected as a new owner of the auditing record based at least in part on a match between a claimant attribute in the auditing record and a claimant field in the update request sent by the triggering function;
• and
• sending, in response to receiving the indication, at least one request to a triggered point of interception (POI) to remove an LI resource corresponding to the failed triggering function.

A system that enables hanging lawful interception (LI) resources to be cleaned up, comprising:

• one or more processors;
• a triggering function set comprising a plurality of triggering functions;
• a data store comprising a plurality of auditing records corresponding to the plurality of triggering functions in the triggering function set, 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 to send an update request to the data store in response to being notified about a failed triggering function within the triggering function set, wherein each update request comprises a request to change ownership of the auditing record corresponding to the failed triggering function;
• select a triggering function as a new owner of the auditing record corresponding to the failed triggering function based at least in part 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 corresponding to the failed triggering function to send at least one request to a triggered point of interception (POI) to remove an LI resource corresponding to the failed triggering function.
