Abstract

A method includes: a) assigning, at a MME, after initiation of a user session of an UE, a correlation ID to the user session; b) defining, at the MME, in response to an initiation of a first trace session of the UE during the user session, a first mapping correlation which maps a first trace ID reflecting the first trace session, to the correlation ID, and sending the first mapping correlation to a TCE; and c) defining, at the MME, in response to an initiation of a second trace session of the UE during the user session, a second mapping correlation which maps a second trace ID reflecting the second trace session, to the correlation ID, and sending the second mapping correlation to the TCE. The first and second mapping correlation enable the TCE to assign trace session information to the user session.
