SYSTEM AND METHOD FOR MANAGING UE-BASED NETWORK PERFORMANCE MEASUREMENTS
First Claim
1. A method of managing User Equipment, UE,-based network performance measurements utilizing a process of tracing a UE in a radio telecommunication network, the method comprising the steps of:
- receiving at an eNodeB, eNB, a trace activation message from a Mobility Management Entity, MME, wherein the trace activation message includes eNB-specific selection conditions for selecting a UE for a trace session;
evaluating by the eNB, the eNB-specific selection conditions; and
initiating the trace session by the eNB toward a selected UE when the eNB-specific selection conditions are satisfied.

Abstract
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 may receive a trace activation message from a Mobility Management Entity, MME, or a Network Management Entity, wherein the trace activation message includes eNB-specific, and optionally MME-specific, selection conditions for selecting a UE 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 activates the trace session with the selected UE. The Trace Activation IE 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.
