Embodiments of the invention include methods, apparatuses, systems and computer programs related to providing a cell traffic trace functionality in E-UTRAN. A cell trace activation message is received (200), a cell traffic trace session is then started for a cell (210), and call set up is started (220). A trace recording session is started and, simultaneously, a unique identifier is generated for the recording session (230). A trace notification may then be sent to a core network or mobility management entity (240). The trace notification may include a trace recording session reference which comprises the unique identifier for the recording session. The IMSI and/or IMEI may also be determined for the call (250), and the trace recording session reference is forwarded to a trace collection entity (260). |
