First Claim
1. A user equipment (UE) operable to connect to a third generation partnership project (3GPP) long term evolution (LTE) cell in a cellular network, having computer circuitry configured to:
- record, at the UE, logged minimization of drive test (MDT) measurements at a selected rate when the UE is in a radio resource control (RRC) idle mode in a first LTE cell in a cellular network;
identify a change in a UE state of the RRC idle mode;
stop recording the Logged MDT measurements at the UE when the UE state changes from a camped normally UE state to another UE state of the RRC idle mode; and
resume recording of the Logged MDT measurements when the UE state changes to the camped normally UE state of the RRC idle mode.

Abstract
A technology for a user equipment (UE) that is operable to connect to a third generation partnership project (3GPP) long term evolution (LTE) cell in a cellular network. Logged minimization of drive test (MDT) measurements can be recorded at the UE at a selected rate when the UE is in a radio resource control (RRC) idle mode in a first LTE cell in a cellular network. A change in a UE state of the RRC idle mode can be identified. The Logged MDT measurements can stop being recorded at the UE when the UE state changes from a camped normally UE state to another UE state of the RRC idle mode. The Logged MDT measurements can resume being recorded when the UE state changes to the camped normally UE state of the RRC idle mode.

10. A method to record minimization of drive test (MDT) measurements at a user equipment (UE) in a cellular network, comprising:
-
recording, at the UE, logged minimization of drive test (MDT) measurements at a selected rate when the UE is in a radio resource control (RRC) idle mode in a first third generation partnership project (3GPP) long term evolution (LTE) cell in a cellular network; identifying a change in a UE state of the RRC idle mode; cease recording the Logged MDT measurements at the UE when the UE state changes from a camped normally UE state to another UE state of the RRC idle mode; connecting the UE to an other LTE cell in the cellular network; and resuming recording of the MDT measurements when the UE state changes to the camped normally UE state of the RRC idle mode when the UE is connected to the other LTE cell. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A user equipment (UE) for use in a communications network, the UE comprising:
-
a cell reselection module for detecting cell re-selection events; and a logging module for storing a logged minimization of drive test (MDT) record when selected cell re-selection events are detected by the cell re-selection module, the logging module further configured to; store a first Logged MDT record at the UE when the cell re-selection module detects a first cell re-selection event; and store a second Logged MDT record at the UE when the cell re-selection module detects a second cell re-selection event, wherein the first Logged MDT record and the second Logged MDT record are used to identify cell boundaries in the communications network. - View Dependent Claims (22, 23, 24, 25, 26)
