2. A method, comprising:
receiving, at a network element in a radio resource control connected mode, a trace session activation request including a job type parameter indicating minimization of drive tests activation and a trace session reference configuration parameter;
generating a trace recording session reference configuration parameter;
causing an activation of a minimization of drive tests measurements at a user equipment;
receiving minimization of drive tests information from the user equipment;
associating the minimization of drive tests information with a user equipment context;
storing the minimization of drive tests information with the trace session reference configuration parameter and the trace recording session reference configuration parameter within a trace record according to the user equipment context;
transmitting the trace record to a collection entity;
receiving, at the network element in a radio resource control connected mode, a trace session activation request including a job type parameter indicating radio link failure information collection;
receiving radio link failure information after a radio link failure;
associating the radio link failure information with the user equipment context;
storing the radio link failure information with the trace session reference configuration parameter and the trace recording session reference configuration parameter within a trace record;
transmitting the trace record to a trace collection entity; and
correlating the radio link failure information and the minimization of drive tests information according to the trace session reference configuration parameter and the trace recording session reference configuration parameter they are stored with.
