job then the radio link failure report collection may also be tied to user consent therefore to avoid user consent requirement for radio link failure report collection a separate trace job can be created the separate trace job however conventionally prevents the possibility of correlating the mdt and radio link failure reports that are collected from the same ue and same connection in certain embodiment radio link failure rlf reports and minimization of drive test mdt reports are collected by separate trace jobs in order to allow radio link failure report collection without user consent however there are certain use cases for example centralized cell change order cco where the mdt and radio link failure reports together in a correlated manner provide valuable information input to a system that analyzes the reports more particularly certain embodiments use c rnti timestamp and cell id for correlation of mdt and radio link failure reports while maintaining a separate trace job for collection of radio link failure and mdt reports using c rnti as a key for correlation can involve various aspects an enb may know the c rnti of the user equipment ue reporting the immediate mdt measurements and it may be added to the mdt log file the enb may also know the c rnti of the ue reporting a radio link failure during re establishment using rel 9 reporting this may also be added to the log file furthermore the ue can add a radio link failure timestamp information element ie to the radio link failure report the combination of c rnti and a timestamp can uniquely or at least uniquely enough identify.
