Method and apparatus for access in terminal of communication network

The invention brings forward a method and apparatus for access in a terminal of a communication network. The method comprises the following steps: receiving a message 2 from a base station, wherein the message 2 is used to distribute resources to transmit a message 3 and the distributed resources correspond to N hybrid automatic repeat request (HARQ) round trip time (RTT) and the N is greater than or equal to 1 and is less than or equal to 8; and sending the message 3 within a portion of the N HARQ RTT. According to the above-mentioned technical scheme, machine type communication (MTC) equipment selectively sends the message 3 only within some HARQ RTT and keeps silent within other HARQ RTT; therefore, the possibility that there is access collision between the MTC equipment and other user equipment (UE) can be eliminated, so that other UE, especially human-to-human UE, can send the message 3 normally. Moreover, the probability of the collision occurrence can also be reduced from the whole perspective of a user terminal in a network, thereby reducing the overall possibility of access delay and access failure.
