<p>A method and apparatus for managing UE-based network performance measurements utilizing a process of tracing a UE in a radio telecommunication network. An eNB (12) may receive a trace activation message from a Mobility Management Entity, MME, (11 ) or a Network Management Entity, wherein the trace activation message includes eNB- specific, and optionally MME-specific, selection conditions for selecting a UE (13) for a trace session. The eNB selects a UE for tracing when the eNB- specific selection conditions are satisfied, and may send the MME-specific selection conditions to the MME for evaluation. When all selection conditions are satisfied, the eNB (12) activates the trace session with the selected UE (13). The Trace Activation SE utilized in the Trace Start message, the UE Context Setup Request message, and the Handover Request message is extended with additional IEs in order to implement the method.</p> |
