Communication method, communication system, and connection apparatus
First Claim
1. A communication method employing a repeating apparatus which can relay communication among a plurality of first communication apparatuses capable of performing half duplex communication, and which performs multi-address calling of output data received from one communication apparatus having acquired transmission right, to the other communication apparatuses having been grouped with said one communication apparatus, said communication method further employing at least one second communication apparatus capable of performing full duplex communication with an apparatus to which call connection has been established and a connection apparatus connected to said repeating apparatus, and said communication method comprising the steps of by said connection apparatus, establishing call connection in full duplex communication to a second communication apparatus;
- by said connection apparatus, performing communication with said repeating apparatus as a proxy of the second communication apparatus having been grouped by establishing the call connection;
by said connection apparatus, transmitting output data received from the second communication apparatus to said repeating apparatus, when the grouped second communication apparatus has acquired transmission right; and
by said connection apparatus, transmitting the received output data to the second communication apparatus, when said connection apparatus receives output data from said repeating apparatus.

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.
