Mobile communication method

A mobile communication method comprising the steps of:

• notifying, by a base station connected to a radio terminal for communications or stand-by, the radio terminal of a parameter for processing for switching to a neighboring base station;
• acquiring, by the radio terminal, movement speed information indicating a movement speed of the radio terminal;
• and
• adjusting, by the radio terminal, the parameter notified by the base station on the basis of the movement speed information, wherein
• the radio terminal adjusts the parameter notified by the base station to inhibit processing for switching to a low-power base station which is included in the neighboring base stations when the movement speed information indicates high-speed movement.

A mobile communication method comprising the steps of:

• acquiring, by a base station connected to a radio terminal, movement speed information indicating a movement speed of the radio terminal;
• selecting, by the base station, a parameter corresponding to the movement speed information from a plurality of parameters including a first parameter for high-speed movement and a second parameter for non-high-speed movement as parameters for processing for handover to any of neighboring base stations;
• and
• notifying, by the base station, the radio terminal of the parameter selected in the selecting step, wherein
• the first parameter is configured to inhibit processing for handover to a low-power base station which is included in the neighboring base stations.

A mobile communication method comprising the steps of:

• reporting, from a radio terminal to a base station connected to the radio terminal, measurement information on a measurement result of a received signal from at least one of the base station and each neighboring base station;
• acquiring, by the base station, movement speed information indicating a movement speed of the radio terminal;
• and
• transmitting, from the base station to a low-power base station, a handover request for requesting an admission of the radio terminal when the measurement information reported from the radio terminal satisfies a handover condition to the low-power base station which is included in the neighboring base stations, wherein
• the base station halts transmission of the handover request to the low-power base station when the measurement information reported from the radio terminal satisfies the handover condition to the low-power base station and the movement speed information indicates high-speed movement.

A mobile communication method comprising the steps of:

• reporting, from a radio terminal to a base station connected to the radio terminal, measurement information on a measurement result of a received signal from at least one of the base station and each neighboring base station;
• acquiring, by the base station, movement speed information indicating a movement speed of the radio terminal;
• and
• transmitting, from the base station to a low-power base station which is included in the neighboring base stations, a handover request for requesting an admission of the radio terminal on the basis of the measurement information reported from the radio terminal, wherein
• the base station transmits the handover request including high-speed movement information when the movement speed information indicates high-speed movement.

A mobile communication method comprising the steps of:

• receiving, by a low-power base station, a handover request for requesting an admission of a radio terminal from a neighboring base station;
• requesting, by the low-power base station, a core network for movement speed information indicating a movement speed of the radio terminal;
• acquiring, by the low-power base station, the movement speed information from the core network;
• and
• transmitting, from the low-power base station to the neighboring base station, a response to the handover request, wherein
• the low-power base station rejects the handover request when the movement speed information from the core network indicates high-speed movement.

A mobile communication method comprising the steps of:

• measuring, by a radio terminal, a received signal from at least one of a base station connected to the radio terminal and each neighboring base station:
• acquiring, by the radio terminal, movement speed information indicating a movement speed of the radio terminal;
• and
• reporting, from the radio terminal to the base station, measurement information on a measurement result obtained in the measuring step, wherein
• when predetermined measurement information on a measurement result of a received signal from a low-power base station is obtained by the measurement and when the movement speed information indicates high-speed movement, the radio terminal reports the measurement information from which the predetermined measurement information is excluded.

A mobile communication method comprising the steps of:

• receiving, by a base station connected to a radio terminal, measurement information on a measurement result of a received signal from at least one of the base station and each neighboring base station from the radio terminal;
• acquiring, by the base station, movement speed information indicating a movement speed of the radio terminal;
• and
• determining, by the base station, a handover target of the radio terminal on the basis of the measurement information received from the radio terminal, wherein
• when predetermined measurement information on a measurement result of a received signal from a low-power base station is included in the measurement information and when the movement speed information indicates high-speed movement, the base station decides the handover target of the radio terminal after excluding the predetermined measurement information which is included in the measurement information.
