摘要： An improvement of an ATM transmission system between a mobileservices switching center and a base station in a mobile communication system. A delay time for generating/sending out a cell is minimized to ensure the information quality required for real time transmission. When the transmission interval of a call type a is T, call types b and c whose periods are twice and four time that of the call type a should be transmitted at intervals twice and four times that of the call type a. A transmitted frame assembler/disassembler 104 in the base station prepares transmitted frames 201 each including the cell slots 201-1, 201-2 and 201-3 for transferring the respective call types, and schedules such that the transmitted frames are sent out to a channel 112 at the interval T, thereby enabling the transmission to be carried out without delay.
