Base station, communication terminal, and call regulation control method

摘要

A base station includes a monitoring unit that monitors whether a supply of electrical power to a first other base station that forms another communication area that is overlapped with a communication area formed by the own station is stopped, and a wireless communication unit that sends, when the supply of the electrical power to the first other base station is stopped, first key data by using a first channel and that sends, after sending the first key data, second key data that is the same as the first key data and a transmission regulation notification indicating that call regulation is performed on the own station by using a second channel.

1. A first base station comprising:
a monitoring unit that monitors whether a supply of electrical power to a second base station that forms another communication area that is overlapped with a communication area formed by the first base station is stopped; and a wireless communication unit that sends, when the supply of the electrical power to the second base station is stopped, first key data by using a first channel through which a first communication terminal accommodated in the first base station is capable of receiving the first key data and a second communication terminal accommodated in the second base station is not capable of receiving the first key data and that sends, after sending the first key data, second key data that is the same as the first key data and a transmission regulation notification indicating that call regulation is performed on the first base station by using a second channel through which both the first communication terminal and the second communication terminal are capable of receiving the second key data and the transmission regulation notification, wherein the first communication terminal and the second communication terminal:
perform a first determination whether the first key data is received by using the first channel;perform a second determination whether the second key data and the transmission regulation notification are received by using the second channel;do not regulate transmission when the transmission regulation notification is received and the received second key data matches the received first key data;regulate transmission when the transmission regulation notification is received and the first key data is not received before the second key data is received; andregulate transmission when the transmission regulation notification is received and the received second key data is different from the received first key data.
