Abstract: Signaling through a plurality of network elements is traced during a trace session. The network elements generate trace records that record information associated with a communication session and that include a charging identifier that is used as a trace recording session reference for the trace session. The charging identifier is a unique network-wide identifier for a subscriber, UE or service and can be used by an operations support system to correlate which trace records are associated with a same subscriber, UE or service that is being traced and, thereby, may enable end-to-end tracing through a network.

Abstract: Methods and arrangements for subscriber tracing based on error history information, are disclosed. A method in a network node (104, 204,600) for providing trace records having error history information comprises receiving trace parameter configuration information (steps S-210, 302, from an Element Manager, EM, (202) activating a trace session, obtaining an error message (steps 304, 406), starting trace recording session (step S-216, 306, 412) if the obtained error message matches the trace parameter configuration information, and providing a trace record (steps S-222, 308, 418) to a trace collection entity (108, 208, 700), for troubleshooting of the network.
