<p>PURPOSE:To attain the real time processing of packet composition at each channel by generating a transmission header corresponding to a channel during communication, adding it to a data extracted from a buffer at each prescribed period to constitute a packet. CONSTITUTION:A processor 1 sets identification information (b) in an identification information memory 3 corresponding to a channel number ch=i set to a call to logical '1'. After a transmission header hi is stored in the transmission header memory 4, a control section 7 references the identification information memory 3 periodically and when a channel number ch=i in which the identification information (b) is set to logical '1' is detected, a header addition circuit 5 adds the transmission header hi extracted from the memory 4 to the data di extracted from a packet composition buffer 2 to compose a data packet pdi. Thus, the assembling load of the data packet is eliminated from the processor 1 and the data packet requesting the real time of voice is composed.</p> |
