Abstract
A communication terminal includes an antenna section and a processor, the processor carrying out: an information acquisition process of acquiring information indicating a location of a base station from the base station by controlling directivity of the antenna section to be a first directivity; and a communication control process of carrying out communication with the base station by controlling the directivity to be a second directivity which is narrower than the first directivity, in the communication control process, the processor deciding the second directivity on the basis of (i) relative locations of the base station and the communication terminal and (ii) a moving speed of the communication terminal.
Claims11
A communication terminal comprising
- an antenna section whose directivity is controllable and
- at least one processor, the at least one processor carrying out:
- an information acquisition process of acquiring information indicating a location of a base station from the base station via the antenna section by controlling the directivity of the antenna section to be a first directivity;
- and
- a communication control process of carrying out communication with the base station via the antenna section by controlling the directivity of the antenna section to be a second directivity which is narrower than the first directivity, wherein
- in the communication control process, the at least one processor deciding the second directivity on the basis of (i) relative locations of the base station and said communication terminal based on the information, (ii) a moving speed of said communication terminal, and (iii) a radio wave map indicating radio wave statuses at respective places, and further wherein
- the at least one processor further carries out an inference process of inferring a destination where said communication terminal reaches after a predetermined time period;
- and
- in the communication control process, the at least one processor decides the second directivity after the predetermined time period with reference to the radio wave map and on the basis of a radio wave status at the destination which has been inferred in the inference process.

A base station comprising at least one processor, the at least one processor carrying out:
- an information acquisition process of acquiring information from a communication terminal that includes an antenna section whose directivity is controllable, the information indicating a first directivity of the antenna section, a location of the communication terminal, and a moving speed of the communication terminal in a case where the communication terminal is communicating with said base station;
- and
- an instruction process of instructing the communication terminal to carry out communication with said base station via the antenna section by controlling the directivity of the antenna section to be a second directivity which is narrower than the first directivity,
- in the instruction process, the at least one processor deciding the second directivity on the basis of (i) relative locations of the base station and the communication terminal based on the, (ii) a moving speed of said communication terminal, and (iii) a radio wave map indicating radio wave statuses at respective places, and wherein
- the at least one processor further carries out an inference process of inferring a destination where said communication terminal reaches after a predetermined time period;
- and
- in the communication control process, the at least one processor decides the second directivity after the predetermined time period with reference to the radio wave map and on the basis of a radio wave status at the destination which has been inferred in the inference process.

A method for controlling communication, said method comprising:
- acquiring, by a communication terminal including an antenna section whose directivity is controllable, information indicating a location of a base station from the base station via the antenna section by controlling the directivity of the antenna section to be a first directivity;
- and
- carrying out, by the communication terminal, communication with the base station via the antenna section by controlling the directivity of the antenna section to be a second directivity which is narrower than the first directivity,
- in the carrying out communication, the second directivity being decided on the basis of (i) relative locations of the base station and the communication terminal based on the information, (ii) a moving speed of the communication terminal, and (iii) a radio wave map indicating radio wave statuses at respective places, and
- inferring a destination where the communication terminal reaches after a predetermined time period, and
- in the carrying out communication, the second directivity after the predetermined time period being decided with reference to the radio wave map and on the basis of a radio wave status at the destination which has been inferred in the inferring.
