<p>A wireless direct mode communication unit (200) is capable of communication with a number of second communication unit(s). The wireless direct mode communication unit (200) comprises a transceiver for transmitting and/or receiving communications to/from the number of second communication unit(s). A signal processing function (208), operably coupled to or comprising a recording function (216, 234), records a communication event between the wireless direct mode communication unit (200) and a number of second communication unit(s). A method of recording a communication event is also provided.</p><p>In this manner, it is possible to track a performance of, messages sent to and/or received from a direct mode communication unit. In particular, it is possible to utilise the recorded information to re-enact an incident at a later time and/or identify how a communication unit/user reacted to a given scenario in a DMO communication system.</p> |
