Abstract

Provided are a communication system, a communication method, and a storage medium capable of improving communication quality between a vehicle and another device. The communication system is a communication system provided in a mobile body and including an acquirer configured to acquire a destination of the mobile body and a position of the mobile body, and a communicator configured to communicatewith a communication device outside the mobile body using an antenna, in which the communicator is configured to set a reception sensitivity of the antenna when the position of the mobile body approaches to within a predetermined distance from the destination of the mobile body to be higher than a reception sensitivity of the antenna before the position of the mobile body approaches to within thepredetermined distance.

Description

technical field [0001] The present invention relates to a communication system, a communication method and a storage medium. Background technique [0002] Conventionally, there is known a technique for transmitting and receiving radio wave information communication between a device mounted on a vehicle and a base station outside the vehicle, based on the traveling angle of the vehicle or the position of the vehicle relative to the position of the base station. Change the directivity of the antenna (for example, Japanese Patent Laid-Open No. 2005-142658). [0003] In addition, in recent years, research on information communication of devices mounted on vehicles using fifth-generation (5G) communication systems has been progressing. Devices mounted on vehicles may communicate with other devices in addition to the base station in the fifth-generation communication system. However, in the conventional technology, even if the antenna can be controlled based on the relationship ...
