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.

Communication apparatus and method for controlling communication system

When receiving an extension connection request from a first mobile terminal, a first route selection device selects a first extension connection route from among a plurality of extension connection routes and transmits the type of the first extension connection route and calling-side address information used on the first extension connection route to a second route selection device. The second route selection device selects a second extension connection route from among the plurality of extension connection routes and transmits the type of the second extension connection route and called-side address information used on the second extension connection route to the first route selection device. If the second extension connection route coincides with the first extension connection route, an extension connection is established between the first mobile terminal and the second mobile terminal via the first extension connection route.

Extension connection method and route selection device

It administers a plurality of wireless base stations grouped into a plurality of groups, and performs the processing about the management, control and maintenance of the wireless base stations selectively for each of the groups. This enables the efficient management, control and maintenance processing of the wireless base stations.
