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.

Base station, communication terminal, and call regulation control method

A communication apparatus is configured to include first and second cards, and a card-to-card link connecting the cards. Each card is communicably connected to another communication apparatus through a route connected to the card. One of the cards is determined to be a primary card that controls data transmission between the communication apparatus and another communication apparatus, and the other card is determined to be a secondary card controlled by the primary card. The primary card establishes a primary data-path for transmitting primary data, using one of the first and second routes connected to the primary card. The primary card further establishes a secondary data-path for transmitting secondary data, using the card-to-card link, the secondary card, and the other one of the first and second routes connected to the secondary card.

Communication apparatus for transmitting data through a plurality of data-paths

In a method for controlling a communication system, the reception device reports a first size of a free space of a buffer in the reception device to the transmission device. The transmission device controls transmission of first data with a first priority to the reception device based on the first size. The transmission device controls transmission of second data with a second priority lower than the first priority to the reception device based on a threshold less than the first size.
