Lawful interception (LI) of electronic communications includes receiving, by a triggering function (TF), a task request including a task identifier (ID) from a LI provisioning function (LIFP). The TF receives an indication of a protocol data unit (PDU) session establishment applicable to the received request, and then triggers (including a POI task ID) each point of interception (POI) applicable to the request. The TF receives a task response indicating a status of the task at the triggered POI. The TF reports, to the LIPF, a TF task issue request indicating the status, the TF task ID, the POI task ID, and a network entity ID of the POI.

A system that enables hanging lawful interception (LI) resources to be cleaned up includes a triggering function set comprising a plurality of triggering functions. The system also includes a data store comprising a plurality of auditing records corresponding to the plurality of triggering functions in the triggering function set. Each auditing record comprises a claimant attribute. Each triggering function sends an update request to the data store in response to being notified about a failed triggering function within the triggering function set. Each update request comprises a request to change ownership of the auditing record corresponding to the failed triggering function. A triggering function is selected 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.

A method for improving availability of a type of network element in a mobile network includes receiving a first message from a source network element at a first network element instance that belongs to a network element anycast set. The first message is addressed to an anycast address that is assigned to the network element anycast set. The first network element instance processes the first message and accesses an anycast set data store in relation to processing the first message. The method also includes receiving a second message from the source network element at a second network element instance that also belongs to the network element anycast set. The second message is also addressed to the anycast address and can be received when the first network element instance is unavailable. The second network element instance processes the second message and accesses the anycast set data store in relation thereto.

A first plurality of UDP packets corresponding to a first session and a second plurality of UDP packets corresponding to a second session can be received at a core network node. The first plurality of UDP packets and the second plurality of UDP packets have the same source five tuple. A first plurality of HTTP packets comprising first session information identifying the first session can be created based on the first plurality of UDP packets. A second plurality of HTTP packets comprising second session information identifying the second session can be created based on the second plurality of UDP packets. The first plurality of HTTP packets can be routed to a first microservice instance based at least in part on the first session information. The second plurality of HTTP packets can be routed to a second microservice instance based at least in part on the second session information.

A method for identifying an active administration function (ADMF) in a lawful interception deployment that utilizes an ADMF set comprising a plurality of ADMFs can be implemented by a network element. The method can include exchanging lawful interception signaling with a first ADMF when the first ADMF is the active ADMF. The method can also include receiving an auditing request message from one of the plurality of ADMFs in the ADMF set and sending a ping request message to each ADMF in the ADMF set. The method can also include receiving a ping response message from a second ADMF among the plurality of ADMFs in the ADMF set and identifying the second ADMF as the active ADMF in response to receiving the ping response message. The method can also include exchanging second lawful interception signaling with the second ADMF when the second ADMF is the active ADMF.
