<p>PROBLEM TO BE SOLVED: To reduce the scale of the device by duplicating data of a common or individual channel and storing a common and an individual storage means which expect data to be transmitted, and deleting the same data as stored data, read out of one storage means to a radio transmission line, from the other storage means. SOLUTION: A radio packet communication device 100 restores received information to packet data, performs processes corresponding to changes of an individual or common channel use signal by user channels, and generates a channel switching indication signal. According to this indication signal, a link control means 104 writes the common or individual packet data to transmission wait buffers 105-0 to 105-n. When they are read out by buffer readout means 106-0 to 106-n and outputted to a radio transmission line 507, the same packet data are deleted from the other transmission wait buffer 105-0 to 105-n. Packet transfer delay at the time of individual-to-common channel switching or reverse switching is reduced and the memory capacity is reduced to make the scale small.</p> |
