Abstract:
1. A random access method based on the number of messages of a base station, comprising: calculating the number of terminals which have transmitted a message, respectively, in ith frame; calculating the number of messages to be transmitted in (i+1)th frame by using the number of terminals which have transmitted the message, respectively, in the ith frame; calculating 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; transmitting the number of messages to be transmitted in the (i+1)th frame and the transmission probability to a plurality of terminals; receiving a message transmitted by at least one terminal among the plurality of terminals according to the result obtained by comparing the transmission probability and a random number, when the number of messages to be transmitted in the (i+1)th frame is greater than the number of random access slots per frame; and receiving the messages transmitted from the plurality of terminal, when the number of messaged to be transmitted in the (i+1)th frame is smaller than the number of random access slots.
