Communications system
First Claim
1. A method performed by a user equipment (UE), having a radio resource control (RRC) connected state and an idle mode, which communicates with a base station, the method comprising:
- receiving, from the base station, a measurement configuration for configuring measurement logging, by the UE, in the idle mode;
logging measurements over time based on the measurement configuration for reporting at a later point in time; and
providing, to the base station, a measurement report to report the logged measurements when the UE is in the RRC connected,wherein the measurement report comprises available UE measurements performed in the idle mode for at least one of intra-frequency, inter-frequency, or inter-RAT, wherein each measurement is provided, in the measurement report, together with location information representing a location of the UE when the measurement was taken and an associated time stamp.

Abstract
A user communications device having active and idle states operates in a cellular communications network in which user communications devices communicate via network communications devices of cells of the network. History data identifying the cells in which the user communications device has been present whilst in the idle state is maintained. This history data is used by the user communications device or by a network communications device to enable adjustment of cell selection/reselection parameters for the user communications device in the active state.

2. A user equipment (UE) that has a radio resource control (RRC) connected state and an idle mode, and which communicates with a base station, the UE comprising:
-
a transceiver circuit configured to receive, from the base station, a measurement configuration for configuring measurement logging, by the UE, in the idle mode; and a processor configured to log measurements over time based on the measurement configuration for reporting at a later point in time; wherein the processor is further configured to provide, to the base station, a measurement report to report the logged measurements when the UE is in the RRC connected, wherein the measurement report comprises available UE measurements performed in the idle mode for at least one of intra-frequency, inter-frequency, or inter-RAT, wherein each measurement is provided, in the measurement report, together with location information representing a location of the UE when the measurement was taken and an associated time stamp.

3. A method performed by a base station, which communicates with a user equipment (UE) having a radio resource control (RRC) connected state and an idle mode, the method comprising:
-
transmitting, to the UE, a measurement configuration for configuring measurement logging, by the UE, in an idle mode; and receiving, from the UE when the UE is in the RRC connected, a measurement report, wherein the measurement report comprises available UE measurements performed over time in the idle mode, for reporting at a later point in time, for at least one of intra-frequency, inter-frequency, or inter-RAT, wherein each measurement is provided, in the measurement report, together with location information representing a location of the UE when the measurement was taken and an associated time stamp.

4. A base station which communicates with a user equipment (UE) having a radio resource control (RRC) connected state and an idle mode, the base station comprising:
-
a transceiver circuit configured to transmit, to the UE, a measurement configuration for configuring measurement logging, by the UE, in an idle mode, wherein the transceiver circuit is further configured to receive, from the UE when the UE is in the RRC connected, a measurement report, wherein the measurement report comprises available UE measurements performed over time in the idle mode, for reporting at a later point in time, for at least one of intra-frequency, inter-frequency, or inter-RAT, wherein each measurement is provided, in the measurement report, together with location information representing a location of the UE when the measurement was taken and an associated time stamp.
