1. A mobile radio terminal, comprising:
- a receiver configured to receive one or more signals from a base station;
a processor configured to;
perform measurements of a received quality of the one or more signals;
obtain location information indicating a location of the mobile radio terminal; and
detect a handover failure by the mobile radio terminal after or during the measurement of the received quality of the one or more signals; and
a transmitter configured to transmit handover failure related information after the handover failure detection,wherein the handover failure related information includes;
a value of the received quality based on the measurements collected by the mobile radio terminal up to a moment of the handover failure detection, andthe location information indicating the location of the mobile radio terminal.
