Abstract
A mobile radio terminal includes a positional information acquisition unit to measure the position of the mobile radio terminal as position information using a Global Positioning System; a reception status acquisition unit to detect a handover failure; and a controller to send information of the position information and handover failure information to a base station.
Claims16
A mobile radio terminal, comprising:
- a receiver configured to receive one or more signals from a base station;
- a memory;
- at least one processor coupled to the memory, wherein the at least one processor is configured to:
- perform first measurements of the one or more signals and second measurements of a ratio based on the one or more signals and an interference;
- detect a handover failure by the mobile radio terminal after or during the first measurements and the second measurements;
- and
- acquire a period of time from a first time,
- wherein the first time is a time at which the handover failure is detected;
- and
- a transmitter;
- wherein the mobile radio terminal is configured to collect results of the first measurements and the ratio up to the first time, and
- wherein the transmitter is configured to transmit, after the first time, the results of the first measurements, the ratio and information about the period of time.

A base station, comprising:
- a transmitter configured to transmit one or more signals to a mobile radio terminal configured to perform first measurements of the one or more signals and second measurements of a ratio based on the one or more signals and an interference;
- and
- a receiver configured to receive, after a first time, results of the first measurements, the ratio and information about a period of time from the first time,
- wherein the first time is a time at which a handover failure is detected,
- wherein the handover failure is detected by the mobile radio terminal after or during the first measurements and the second measurements, and
- wherein the results of the first measurements and the ratio are collected by the mobile radio terminal up to the first time.

A method of a mobile radio terminal, the method comprising:
- receiving one or more signals from a base station;
- performing first measurements of the one or more signals and second measurements of a ratio based on the one or more signals and an interference;
- detecting a handover failure by the mobile radio terminal after or during the first measurements and the second measurements;
- acquiring a period of time from a first time,
- wherein the first time is a time at which the handover failure is detected;
- collecting, by the mobile radio terminal, results of the first measurements and the ratio up to the first time;
- and
- transmitting, after the first time, the results of the first measurements, the ratio and information about the period of time.
