ABSTRACT:
A connection apparatus is employed which is connected to a repeating apparatus for providing the PoC for first communication apparatuses having a PoC function. Call connection is established between the connection apparatus and second communication apparatus not having the PoC function. In the connection apparatus, recorded is apparatus information for identifying each second communication apparatus. The connection apparatus has the function of acting as a proxy of the second communication apparatus identified by the apparatus information. This function consists of the function of performing half duplex communication with the repeating apparatus; the function of transmitting output data received from the second communication apparatus, to the repeating apparatus when the second communication apparatus has acquired transmission right; and the function of transmitting received output data to the second communication apparatus when the output data is received from the repeating apparatus.
