Wireless communication terminal, communication control support terminal, communication system, communication environment state notification method, communication environment state notification program, and recording medium thereof

摘要

PPROBLEM TO BE SOLVED: To provide a wireless communication terminal that can easily inform a user of a communication environment condition such as a presence of other communication device participating in communication, a state of whether or not a communication device can perform communication, a change in a permitted communication range, and the like, to provide a communication control support terminal, to provide a communication system, to provide a method for reporting communication environment condition, to provide a program for reporting communication environment condition, and to provide a recording medium therefor. PSOLUTION: The wireless communication terminal 100 which can measure a distance from the wireless communication terminal 100 to a communication partner includes a terminal position calculation means 31 for calculating a position of the wireless communication terminal 100 based on reference positions that indicate positions of at least three communication control support terminals 200 for specifying a reference point of a permitted communication range R and a distance from the wireless communication terminal 100 to the communication control support terminal 200, a determination means 32 for determining whether the wireless communication terminal 100 is located within the permitted communication range based on the position of the wireless communication terminal 100 calculated by the terminal position calculation means 31, and a report means 33 for reporting the communication environment condition of the wireless communication terminal 100 based on the result determined by the determination means 32.
