    • A base station calculates the number of terminals which have transmitted messages at ith frame, and calculates the number of messages to be transmitted at (i+1)th frame by using the number of terminals which have transmitted the messages in the ith frame. The base station calculates a transmission probability by using the number of messages to be transmitted in the (i+1)th frame and the number of random access slots, and transmits the number of messages to be transmitted in the (i+1)th frame and the transmission probability to the plurality of terminals. The base station receives a message transmitted by a pertinent terminal, whose number of messages to be transmitted in the (i+1)th frame is greater than the number of random access slots, among the plurality of terminals, according to the result obtained by comparing the transmission probability and a random number.
    • 基站计算在第i帧发送消息的终端的数量,并且使用在第i帧中发送了消息的终端的数量来计算在第(i + 1)帧发送的消息的数量。 基站通过使用在第(i + 1)帧中发送的消息的数量和随机接入时隙的数量来计算发送概率,并且发送第(i + 1)个发送的消息的数量 帧和传输概率到多个终端。 根据由第(i + 1)帧中发送的结果获得的结果,基站接收由相关终端发送的消息,其中在第(i + 1)帧中要发送的消息的数量大于随机接入时隙的数目 比较传输概率和随机数。
