In existing mobile networks, users may be traced to troubleshoot problematic user connections, monitor generic network performance, and to perform root cause analysis to identify network problems. However, the existing tracing methods provide incomplete trace information. To address this and other issues, early tracing recording is enabled in which an involved trace entity starts recording the trace data when any initial activity related to the user equipment is detected. The trace entity can continue the trace if a trace trigger is later confirmed or may discard the trace data if the trigger is not confirmed.

Method, apparatus and system for flexible user tracing in mobile networks

A method of handling performance data comprising a set of events is described. An event record for each event is stored as a set of blocks, each block containing one or more attributes of the event. The storage space occupied by each event record in is then reduced in discrete steps, each step including a reduction process that reduces the size of one of the set of blocks. This enables the provision of intermediate records between events and counters so that new event records contain complete details of their event, older event records contain less information, and even older event records may contain only high-level (counter) information.
