Abstract
A first radio base station (RBS) is operated to cause trace log information to be supplied to a trace log storage node. The RBS becomes responsible for serving a user equipment session, and at some point begins a trace process. When the session report criterion has been satisfied, a trace status indication is alternatively sent to or received from a second radio base station, the trace status indication including an indicator of a session report cause and a time of satisfying the session report criterion. The indicator of the session report cause and the time of satisfying the session report criterion are used to identify a set of trace log information stored in a record buffer. If not empty, the set of trace log information is supplied to the trace log storage node.
