Abstract:
1. A transmission apparatus for use in a radio communication system wherein the transmission apparatus communicates with a reception apparatus through a radio channel, said transmission apparatus comprising: monitoring means for monitoring whether or not a transmission request for data, designating the transmission apparatus itself as a transmission destination, has been issued by said transmission apparatus or the reception apparatus connected thereto through a network; generation means for generating and initiating a process in the transmission apparatus to serve as a logical reception destination for the data and generating a buffer in correspondence with the process, when said monitoring means has detected the issue of the transmission request; transfer means for transferring the data from a transmission request source to said process in accordance with communications of an internal virtual circuit type, so as to store in the buffer the data transmitted by the transmission request source; and transmission means for transmitting the data stored in said buffer, to said reception apparatus through the radio channel; wherein when a plurality of such buffers are generated by said generation means, said transmission means reads out data successively from the buffers of higher priority levels in accordance with priority levels set for the respective buffers and transmits the read data.
