PURPOSE:To reduce the number of time slots to be used for the transfer of the same data volume and to improve line efficiency in a time-divided multiconnection channel access system. CONSTITUTION:If lines are congested, the mutual collision of data slotted ALO HA system data is frequently generated and much data are stored in a peripheral station in the case of using both slotted ALOHA system and slot reservation system in the time-divided multiconnection channel access system, only one header is added to plural data and plural data are collectively sent to one reservation slot. Thereby the number of time slots to be used for the transfer of the same data volume can be reduced in comparison with a case for using one time slot in each data. Since long data over several time slots can be sent to one reservation slot without dividing them, the increment of overhead due to packet division can be prevented. |
